Audi A4 and Q7 plug-in hybrid e-tron models confirmed

During his keynote speech at today's annual press conference, Audi Chairman, Rupert Stadler expanded on what to expect from the future of Audi's e-tron model line. Noting that "the electric driving experience will become a reality for a growing clientele with our plug-in hybrids," Stadler confirmed that in addition to the A3, Audi will launch plug-in hybrid models of the A4 and Q7 starting in 2014. More after the jump.

Though typically associated with fully electric vehicles, Audi's e-tron nameplate encompasses the company's plug-in hybrid models as well (as seen on the A3 e-tron concept). As Stadler stated directly following his comments on the A4 and Q7, "In 2020, we want to have an e-tron available in every segment."

Below is an excerpt from Rupert Stadler's speech today at the Audi annual press conference 2012.

"Our A1 e-tron has been out on the roads since September 2011. In a pilot project with a vehicle fleet in the greater Munich area, test customers are using it under everyday conditions. We will utilize the results in the "Showcasing Electromobility" projects funded by the German federal government. Under our e-tron master plan, Audi intends to follow the launch of our hybrid models this year with the launch of our first electric vehicle: the R8 e-tron.

While we are planning small-scale series production for this car, which is a vital element in our innovation and technology plans, the electric driving experience will become a reality for a growing clientele with our plug-in hybrids. Our pioneering vehicle in this field is the Audi A3, with the market launch of a plug-in version slated for 2014. This will be followed by the next-generation Audi A4 and Audi Q7 plug-in cars – starting in 2014 and in successive years. In 2020, we want to have an e-tron available in every segment and to achieve total sales in the six-figure range."

Audi R18 e-tron quattro and R18 ultra officially revealed

After much speculation, Audi Sport has officially debuted the all-new, R18 e-tron quattro. First off, yes, the word "quattro" has officially returned to Audi's motorsport vocabulary.As part of it's new e-tron, hybrid powertrain, the new R18 e-tron quattro makes use of Audi's dominating all-wheel drive technology in a new and unique way. In addition to the R18 e-tron quattro, Audi Sport has also revealed the R18 TDI's evolution, known simply as the R18 ultra. Full report (including 2012 driver lineup) and photo gallery after the jump.

Ingolstadt/Munich, February 29, 2012 – Motor sport is used yet again by AUDI AG to pioneer new technology: the brand with the four ring’s new Le Mans race car is the world’s first LMP1 car to combine a highly-efficient TDI with a hybrid system. quattro drive also celebrates its comeback to the race track with the prototype – in a entirely new form.

Audi R18 e-tron quattro is the name of the new Le Mans prototype that makes its race debut on May 5 in the 6-hour race at Spa-Francorchamps (Belgium) and fights for overall victory at the famous 24 Hours of Le Mans (France) on June 16/17. Audi unites two technologies in a fascinating way to create a new type of drive, which is also already being tested for future use in production cars: e-tron quattro.

Hiding behind this description is the next generation four-wheel drive with which Audi combines the advantages of the proven quattro drive with the potential of electromobility. To this end one vehicle axle is powered conventionally, the second by electric motors.

"Audi has always consciously selected championships and categories in racing that have a close relationship to production and therefore have technical relevance for the Audi customers,” explains Head of Audi Motorsport Dr. Wolfgang Ullrich, who personally drove the new Audi R18 e-tron quattro onto the stage on Wednesday evening during its world premiere in the Audi Training Center at Munich airport – electrically and almost silent. "quattro, TFSI and TDI are three excellent examples of how motorsport has stimulated production development. A similar tendency is apparent with the e-tron quattro: we test a completely new technology on the race track before it’s introduced to the Audi production line.”

On the Audi R18 e-tron quattro kinetic energy is recovered on the front axle during the braking phase. It is fed as electric into a flywheel accumulator before being retrieved under acceleration again above a speed of 120 km/h. During this procedure only the front axle is integrated. The V6 TDI power plant producing 375 kW (510 hp) continues to transmit its power to the rear wheels. Both systems complement each other to create the new drive principle e-tron quattro.

Project began in February 2010
The project e-tron quattro for motorsport started in February 2010. Only 18 months passed from the initial conceptual ideas to the first test. "This is a relatively short cycle for a technology that has never been tested in motorsport and which still doesn’t even exist in production,” stresses Dr. Martin Mühlmeier, Head of Technology at Audi Sport. "The challenge is correspondingly big.”

Audi Sport developed the Audi R18 ultra in parallel to the Audi R18 e-tron quattro – because Audi takes a two-pronged approach this year in the 24 Hours of Le Mans and in the newly created FIA World Endurance Championship (WEC) – the 2012 model year Audi R18 is built with and without hybrid drive. The trick: the base of both cars is completely identical, which is why the additional logistical effort is kept limited for Audi Sport and the race team.

"The TDI engine invented by Audi is still the most efficient drive in the world,” says Dr. Wolfgang Ullrich. "We are convinced that the TDI has even more potential. This is why Audi not only supports the hybrid in motorsport as it does in production, but in parallel also the further development of the conventional drive.”

Innovation in transmission area
The R18 e-tron quattro’s twin brother more than lives up to its model name ‘R18 ultra’: it is the lightest Le Mans prototype that Audi Sport has ever built. To compensate for the additional weight of the hybrid system the subject of lightweight design and construction was the focus throughout development of the 2011 Le Mans race winning R18 TDI. In addition to the many detail optimizations there is also a genuine innovation in the transmission area: a new gearbox with a carbon-fiber composite housing was developed for the R18 – a premiere for endurance racing.

"The new R18 ultra is a distinct evolution of last year’s Le Mans race winning car,” summarizes Head of Audi Motorsport Dr. Wolfgang Ullrich. "Our drivers’ impressions were very positive from the first moment. Without the weight optimized R18 ultra we would have not been capable of realizing the R18 e-tron quattro which is absolutely identical with the exception of the hybrid system.”

Le Mans 2012: two R18 e-tron quattro and two R18 ultra
Audi Sport Team Joest will field two R18 e-tron quattro and two R18 ultra prototypes in the Le Mans 24 Hours on June 16/17. The two hybrid cars are driven by last year’s winning trio Marcel Fässler (CH), André Lotterer (D) and Benoît Tréluyer (F) as well as Dindo Capello (I), Tom Kristensen (DK) and Allan McNish (GB) who boast a total of 13 Le Mans wins between them. New signing Loïc Duval (F) starts together with Timo Bernhard (D) and Romain Dumas (F) in an R18 ultra as do Marco Bonanomi (I), Oliver Jarvis (GB) and Mike Rockenfeller (D).

Audi Sport Team Joest also contests the World Championship round at Spa-Francorchamps (Belgium) on May 5 in the same formation. At the same time the race doubles as a dress rehearsal for the 24 Hours of Le Mans. Only Mike Rockenfeller will miss this race due to a clashing date with the DTM.

After the 24 Hours of Le Mans, Audi plans to enter an R18 e-tron quattro and an R18 ultra in the FIA World Endurance Championship (WEC). André Lotterer and Allan McNish have been nominated as the drivers so far.

At the World Championship opener at Sebring (USA) on March 17, Audi Sport Team Joest relies on the proven R18 TDI from last year, which are driven by Marcel Fässler/André Lotterer/Benoît Tréluyer, Dindo Capello/Tom Kristensen/Allan McNish as well as Timo Bernhard/Romain Dumas/Loïc Duval.

Audi Sport goes hybrid for 2012 24 Hours of Le Mans

In addition to two "regular" R18 TDIs, Audi Sport will enter—for the first time ever—a pair of "hybrid drive" R18s at this year's 24 Hours of Le Mans in June. Though full driver lineups have yet been released, Audi Sport has announced their lead drivers for Le Mans will be André Lotterer in car #1 (hybrid), Allan McNish in car #2 (hybrid), Timo Bernhard in car #3 and Oliver Jarvis leading car #4. Look for the R18 hybrid prototypes to be officially revealed later this month. Full report after the jump.

Ingolstadt/Paris, February 2, 2012 – Audi competes in the 80th running of the legendary 24 Hours of Le Mans on June 16–17, 2012 with a total of four LMP1 sports cars. Two of the four cars in action will be equipped with hybrid drive for the first time. Audi Sport Team Joest also follows a two-pronged approach in the newly created FIA World Endurance Championship (WEC) during the 2012 season.

Following the first win for a TFSI engine (2001) and the historical first triumph for a diesel powered car (2006) the brand with the four rings targets yet another technical milestone at the world’s most famous and most important endurance race. "To develop the hybrid technology for Le Mans is at least as ambitious and challenging as our diesel project was in its early stages,” explains Head of Audi Motorsport Dr. Wolfgang Ullrich. "The first test results are very encouraging and we are intrigued to see just how this technology performs in combination with our ultra lightweight technology on the race track at Le Mans. As before, we still, however, see potential with the conventional drive – just as our colleagues do in production development. This is why we are absolutely delighted that the ACO and FIA selection committee has accepted our entries and that we can join the grid with four cars at the commemorative running of the Le Mans race.”

Audi Sport Team Joest has entered two cars for the new FIA World Endurance Championship (WEC). Audi plans to field additional cars at selected races such as the 12-hour race at Sebring (USA) and in the 6-hour race at Spa-Francorchamps (Belgium) which doubles as a dress rehearsal for Le Mans for the Audi squad.

At the 80th running of the French endurance classic, Audi competes with the start numbers ‘1’ and ‘2’ (hybrid drive) as well as ‘3’ and ‘4’. As stipulated by the regulations one driver per car is now nominated. Those drivers are André Lotterer, Allan McNish, Timo Bernhard and Oliver Jarvis.

The new Audi sports prototype with hybrid drive will be presented at the end of February. The first competitive outing follows in the 6-hour race at Spa-Francorchamps on May 5. For the World Championship opener at Sebring on March 17 Audi Sport Team Joest relies once again on the Audi R18 TDI that proved victorious at Le Mans last year. Audi has won the 24 Hours of Le Mans a total of ten times since the year 2000 and is, as a result, the most successful brand by far in race’s recent history.

Video: Audi e-tron Spyder caught on the road in California

We just came across a very cool video on YouTube catching the Audi e-tron Spyder "in the wild." Look closely and you'll notice this car is slightly different than the concept revealed last year in Paris (the added vents in the hood). Surrounded by corporate Q7s and crew, it appears Audi was filming the car on California's scenic Mulholland Drive, most likely for a new PR campaign. It seems that after nearly a year, we haven't seen the last of the e-tron Spyder.

Unfortunately, we are unable to embed the video (it's been disabled by the user), so you'll have to go directly to YouTube to watch.

Needless to say, details are scarce but obviously Audi has something new planned for the e-tron Spyder. We'll be sure to keep this on our radar and update when we know more.

UPDATE: It turns out that in addition to a corporate photo shoot, Audi invited select journalists to drive this car in California (that is what you're seeing in this video). We've included links to the various stories and Audi photo galleries below.

Audi A3 e-tron concept revealed

Making its world debut at the 2011 Shanghai Auto Show, Audi has officially revealed the A3 e-tron concept. Considering the A3 Sedan concept first graced our pages nearly two months ago, the A3 e-tron's styling is - while still quite stunning to look at - nothing new. But as its "e-tron" name denotes, a highly efficient (and powerful) plug-in hybrid drivetrain is new under the hood. More info, photo gallery, video and press release after the jump.

As the styling, chassis, and interior is nearly identical to the Sedan concept, we'll focus on the drivetrain and the leave the other details for the press release below. Powering the A3 e-tron are two power units: a 211 hp (155-kW) 1.4 TFSI four-cylinder engine with turbocharging and gasoline direct injection and an electric motor with an output of 27 hp (20 kW), making for a combined output of 238 hp (175 kW). All told, this system is enough to launch the concept from 0-62 mph in 6.8 seconds on to a top speed of just over 143 mph - all the while offering a range of up to 34 miles on electric power alone.

Delving deeper into the electric/hybrid aspect of the A3 e-tron, Audi explains: "The [lithium ion] batteries are charged by the standard energy recovery system when the car is in motion or directly from a household power socket when it is parked. This means that in most cases, the car is entirely emission-free in city driving."

Finally, as seen in previous e-tron concepts, the A3 e-tron makes use of "the full breadth of the brand’s technological expertise – from the enhanced MMI operating system, to the high-end infotainment system" - full details of which can be found in the official press release following the video and photo gallery below.







Press Release:

Concentrated technical expertise – in the Audi A3 e-tron concept

Shanghai/Ingolstadt, 2011-04-19: Audi is set to unveil an attractive technical study – the A3 e-tron concept – in Shanghai. The four-seat notchback sedan integrates the full breadth of the brand’s technological expertise – from the enhanced MMI operating system, to the high-end infotainment system, to the drivetrain. And with its two powerplants and lithium-ion batteries that store enough energy to propel the car on electric power alone for up to 54 km (34 miles), the plug-in hybrid also delivers high fuel efficiency.

Design and body
The Audi A3 e-tron concept is a four-seat notchback sedan. It measures 4.44 meters (14.57 ft) long and 1.84 meters (6.04 ft) wide, but just 1.39 meters (4.56 ft) high – proportions that underscore its dynamic character.

The design represents the typical Audi language of sporty elegance. The single-frame grille is integrated into the front end, giving it a sculptured look. Its frame is made of carbon fiber-reinforced polymer (CFRP), and the transversely mounted, three-dimensional aluminum louvers create a visual effect that emphasizes the showcar’s width. The headlights merge with the beveled upper corners of the single-frame, forming a transition that marks the starting point of the prominently accentuated lines of the engine hood.

The headlights represent a new stage of evolution in LED technology, a groundbreaking innovation from Audi. They become broader as they extend outward, and a line underneath makes them seem to float on air. Above the front spoiler is a full-length air intake, also made of CFRP, framed by a metal clasp. The spoiler features a splitter that increases the downforce on the front wheels.

When viewed from the side, too, the A3 e-tron concept is recognizable at first sight as an Audi – with its harmonious proportions, taut, muscular surfaces and a low roof dome with fluid lines flowing into a flat, coupe-like C-pillar. The shoulder area transitions elegantly into the tailgate. Characteristic of Audi design, the greenhouse accounts for one-third of the height, while the sheet metal makes up the remaining two-thirds.

Powerfully flared fenders hint at the power of the engine. Two prominently elaborated lines accentuate the flank: the undercut tornado line beneath the window edge and the dynamic line above the sills. The exterior mirrors, made of aluminum and CFRP, are perched atop the window-channel strips. The door handles with their brushed-aluminum clasps are recessed flush with the door. When the driver touches them, they power-extend.

The intelligent interplay between surfaces and lines also defines the tail end of the A3 e-tron concept. The broad, flat tail lights are sculptured and culminate in a point on the inside, and the tailgate bears an elegant spoiler edge. The rear apron includes a diffuser insert of CFRP and metal, which in turn surrounds the two large tailpipes for the exhaust system.

Ultra-modern components, design methods and joining techniques keep the body weight low. One example of this are the custom tailored blanks (panels of various thicknesses) in the floor area. The doors, engine hood and tailgate are made of aluminum. With its high levels of rigidity, the body provides the basis for the sedan’s precise handling, excellent vibrational comfort and low weight – the Audi A3 e-tron concept tips the scales at just 1,720 kilograms (3,792 lb).

Interior
The interior of the showcar is generously proportioned. The long wheelbase measuring 2.63 meters (8.63 ft) – a best-in-class figure in the premium compact segment – gives rear passengers on the two individual seats a pleasing amount of knee room. The front sport seats with prominent side bolsters are slim and elegant.

The cockpit, too, gives an impression of lightness and airiness. The horizontal lines emphasize its design. The instrument panel draws the driver in – typical of Audi. Defined in three dimensions, the large trim strip is made of solid aluminum and includes control functions. The high-quality sound system in the doors and on the rear shelf has aluminum trim panels. When the audio system is turned on, they extend a few millimeters, thus orchestrating a visual accompaniment to the system’s excellent sound.

On the center console, four large, round air vents echoing a jet’s design catch the eye. The air flow is adjusted by pulling and pushing on the center axis of the vents. The control knobs for the automatic air conditioning system are located in the lower section of the center console on a boldly protruding, dedicated control panel. Visually, they are reminiscent of airplane turbines.

Behind the compact, flat-bottomed, three-spoke multifunction steering wheel is an innovative display concept that renders the individual driving states of the hybrid drive clear-cut and tangible. The tachometer on the instrument cluster has been replaced by a “power meter,” with a needle that indicates the total system output on a scale of 0 to 100 percent. A second scale is divided into colored segments. At a glance, the green and orange segments clearly indicate where the A3 e-tron concept is drawing its power – from the electric motor, the combustion engine, or a combination of both. An additional instrument displays the charge level of the battery.

In between the two large round dials is the large, eight-inch display for the driver information system. This display and the large monitor of the MMI system show the operating states and power flows in the hybrid system in elegant graphics with a three-dimensional effect.

The MMI monitor also displays differentiated consumption and recuperation statistics in easily understandable bar graphs.

The control panel for the MMI multimedia system is located on the center tunnel console. The interface on its large rotary pushbutton features another novelty – the “MMI touch” touchpad. This new solution, which makes the already exemplary operation even more intuitive, will soon be introduced in series production at Audi. The ultra-thin MMI monitor power-extends upwards out of the instrument panel, another feature taken from the full-size car class.

In terms of infotainment, the Audi A3 e-tron concept shows why the brand is leading the competition. A UMTS model provides full access to the Internet, allowing the car to retrieve convenient services from Google. Thanks to the WLAN hotspot, passengers can surf and send e-mail to their hearts’ content. Holders for iPads are installed on the back of the front seat backrests.

A classic notchback sedan, the Audi A3 e-tron concept boasts a large luggage compartment with a volume of 410 liters (14.48 cubic ft) and a low loading lip.

Drivetrain
Designed as a plug-in hybrid, the A3 e-tron concept is propelled by two power units – a 155-kW (211-hp) 1.4 TFSI four-cylinder engine with turbocharging and gasoline direct injection and an electric motor with an output of 20 kW (27 hp). The system provides a combined output of 175 kW (238 hp). Working together, the gasoline engine and electric motor accelerate the notchback to 100 km/h (62.14 mph) in 6.8 seconds, then on to 231 km/h (143.54 mph). A regulated oil pump, the intelligent Audi thermal management system, a start-stop system and an energy recovery system – technologies from the brand’s modular efficiency platform – all contribute to this high efficiency.

At the heart of the A3 e-tron concept are the lithium-ion batteries located behind the rear seats. With a charge capacity of 12 kWh, they give the notchback a range of up to 54 km (34 miles) on electric power alone.

The batteries are charged by the standard energy recovery system when the car is in motion or directly from a household power socket when it is parked. This means that in most cases, the car is entirely emission-free in city driving.

A compact seven-speed S tronic serves as the transmission for the compact plug-in hybrid. It comprises two transmission structures, which are operated by two clutches. Gears are alternately shifted by the two clutches – at lightning speed, comfortably, and without any perceptible interruption of traction.

The driver can operate the seven-speed S tronic in one automatic mode and one manual mode, using the paddles on the steering wheel to shift gears manually. Elegant touch control buttons alongside the handrest on the center tunnel console are used to select drive positions R, N and D. These are backlit in red when it gets dark. Drive position P is automatically engaged when the electric parking brake is applied. The launch control system manages the sprint from a dead stop, furnishing explosive turbo power with minimal tire slip.

Chassis
Derived from the current RS 3 Sportback, the Audi A3 e-tron concept’s chassis is fully capable of handling the power from the drive system at all times. The four-seater masters any type of curve with speed, stability and composure. Its self-steering response remains essentially neutral all the way up to the lofty handling limits.

The front suspension – a MacPherson construction with a separate axle support – has a track measuring a full 1,572 millimeters (61.89 in). The rack-and-pinion steering is extremely efficient because its electromechanical drive system requires no energy when driving straight ahead.

The four-link rear suspension with its 1,542-millimeter (60.71-in) track is likewise fixed to a subframe. Its control arms made of high-strength steel enable the suspension to absorb longitudinal and lateral forces separately. The shock absorbers and coil springs are mounted separately from each other.

The Audi drive select dynamic handling system gives the driver five modes from which to select the characteristics of the engine, power steering and seven-speed S tronic. The modes are comfort, auto, dynamic, individual and efficiency, the last of which is designed for maximum economy.

The imposing light-alloy rims measure 20 inches in diameter. The tire format is 245/30 at the front and rear. The front brake disks are gripped by four-piston calipers. The ESP stabilization system has a Sport mode and can be completely deactivated. The parking brake is actuated electromechanically.

The equipment and data specified in this document refer to the model range offered in Germany. Subject to change without notice; errors and omissions excepted.

Audi Q5 hybrid quattro: Full details and specifications

Yesterday, we posted the first details (and a couple of videos) of the Audi Q5 hybrid quattro. At the time, we mentioned that "we imagine more in-depth coverage will be available soon." We had no idea that "soon" would mean a matter of hours. Considering the vast quantity of technical jargon that's associated with the Audi Q5 hybrid, we'll allow Bernd Huber, Technical Project Manager of the Audi Q5, explain everything after the jump.



The Audi Q5 hybrid quattro – The First Full Hybrid in the Premium Mid-sized Class
- Bernd Huber, Technical Project Manager, Audi Q5

Power like a V6, fuel consumption like a four-cylinder TDI – after three generations of the Audi duo, the Q5 hybrid quattro is the first hybrid model from Audi with two drive systems. Its gasoline engine, a 2.0 TFSI, and its electric motor have a system output 180 kW (245 hp) and 480 Nm (354.03 lb-ft) for sporty dynamics – the mean consumption in the normal cycle (NEDC) is limited to less than 7.0 liters per 100 km (33.60 US mpg).

During the development process, Audi focused on a high share of electrically powered driving. The sportiest hybrid SUV on the market covers about three kilometers (1.86 miles) locally emission-free at a speed of 60 km/h (37.28 mph), and can drive up to 100 km/h (62.14 mph) under electric power alone. With the equally powerful and lightweight lithium-ion battery and many other solutions, the Audi Q5 hybrid quattro represents the state of the art.

Performance
The 2.0 TFSI and the electric motor of the Audi Q5 hybrid are mounted directly behind one another as a parallel hybrid system – a straight-line concept with impressive efficiency. Together they have a system output of 180 kW (245 hp) and a system torque of 480 Nm (354.03 lb-ft). The new top model in the successful Q5 series sprints from 0 to 100 km/h (62.14 miles) in 7.1 seconds, while the interim sprint from 80 to 120 km/h (49.71 to 74.56 mph) is accomplished in fifth gear in 5.9 seconds. The powerful propulsion ends at no less than 222 km/h (137.94 mph).

The consumption by the Audi Q5 hybrid quattro lies under 7.0 liters per 100 km (33.60 US mpg) in the normal cycle – that corresponds to a CO2 emission of less than 160 g/km (257.50 g/mile). The 75 liter (19.81 US gallon) tank yields a reliable range comparable to that of a TDI.

The Drive
The 2.0 TFSI in the Audi Q5 hybrid quattro has a displacement of 1984 cc (121.08 cu in). Its output is 155 kW (211 hp), with the maximum torque of 350 Nm (258.15 lb-ft) permanently available at 1500 to 4200 rpm. The 4-cylinder engine combines direct injection with turbocharging – typical for the Audi philosophy of downsizing, which replaces displacement by charging. The Audi valve lift system (AVS) further increases power, torque and efficiency by switching the stroke of the exhaust valves between two stages depending on the load and rpm.

The 2.0 TFSI has been overhauled in some respects for use in the Audi Q5 hybrid. The drive of the ancillary units has been dropped, and the crankshaft bearing and fine tuning of the turbocharger have been adapted to the specific demands. A secondary air system at the cylinder head makes sure that the exhaust gas treatment cuts in particularly fast. Integrated in the engine control unit, the so-called hybrid manager controls the efficient change and smooth transitions between the operating modes, and was fully developed by Audi alone.

A largely modified eight-speed tiptronic serves the power transmission without the aid of a torque converter. Its place is taken by the disk-shaped electric motor, combined with the multi-plate clutch operating in an oil bath – it couples and decouples the electric motor and the TFSI. The innovative decoupler operates with high precision, smoothly and quickly in any situation.

The highly comfortable and fast-shifting hybrid gear unit contributes significantly to the efficiency of the Audi Q5 hybrid – its eight gears are widely spaced. When the 2.0 TFSI is turned off, an electric pump maintains the oil pressure in the hydraulic system to safeguard the convenient start-stop feature.

The Power Electronics and the Electric Motor
The power electronics, connected to the battery and the electric motor by high-voltage cabling, is located in the plenum chamber of the engine compartment. In the form of a so-called pulse-controlled inverter, the power electronics serves as a controller between the battery, which outputs direct current, and the electric motor that operates on alternating current.

Innovative technologies keep the volume and weight of the power electronics low, with cooling provided by a separate low-temperature water-filled circuit. The component includes a DC/DC converter that couples the electric consumers in the 12 V electrical system with the high-voltage network.

A so-called permanently excited synchronous machine serves as an electric motor, as a starter and – during deceleration – as a generator. It outputs up to 33 kW (45 hp) of power and 211 Nm (155.63 lb-ft). The electric motor is integrated in the cooling circuit of the engine.

The Battery
A lithium-ion battery system, weighing merely 38 kg (83.78 lb), serves as the energy store for the electric motor of the Audi Q5 hybrid quattro. The compact unit with its 26 liter (6.87 US gallon) capacity is positioned in a crash-safe area under the loading floor, with hardly any detriment to the luggage compartment. The battery consists of 72 cells; at 266 volts its nominal energy is 1.3 kWh and its output 39 kW.

The lithium-ion battery is cooled by air in two ways, depending on the requirement. At low-temperature load, it draws temperate air from the vehicle interior by way of a fan. If its temperature exceeds a certain limit, a separate refrigerant circuit is activated. It is coupled to the main climate control system of the vehicle and uses a separate evaporator.

This heavy-duty active cooling system distinguishes the Audi Q5 hybrid quattro from many other hybrid vehicles, and makes a key contribution to the high electrical availability of the hybrid system.

The Operating Modes
With its parallel hybrid system the Audi Q5 hybrid quattro can travel in five different operating modes. Driving with the combustion engine alone, with the electric drive alone or in hybrid mode is possible, as are recuperation and boosting.

At a standstill, e.g. before starting or at a traffic light, both drive sources are deactivated. In this convenient start-stop mode the climate control system remains active. Once the driver releases the brake, the Audi Q5 hybrid quattro starts rolling. It can be driven up to 100 km/h (62.14 mph) under electric power – with almost no noise or local emissions. At a constant 60 km/h the possible range is three kilometers (1.86 miles) – this high electrical share of the driving suffices for most residential areas and many urban centers.

The driver can change between three programs using a button on the center console or a selector lever. The EV characteristic map gives priority to the electric drive in the city, the D mode controls both motors for optimal consumption, and the S mode as well as the touch control gate of the tiptronic are designed for a sporty driving style.

When the driver accelerates sharply, the combustion engine serves as a power source for the drive. The electric motor is then actuated by the operating strategy in order to achieve optimal efficiency and consumption. In quick acceleration, or "boosting," the electric motor operates together with the TFSI; at full throttle in the S mode the full system output is briefly available. The hybrid drive then supplies the propulsion power of a large naturally aspirated engine, but with far more efficiency.

When the driver releases the accelerator, the electric motor acts as a generator and recovers energy. In most situations the TFSI is then decoupled from the drive system so as not to cause any loss from towing. The electricity recovered by the electric motor here and in braking is buffered in the lithium-ion battery. If the driver brakes only slightly, the electric motor performs the deceleration itself; in more forceful braking the hydraulic braking system is simultaneously activated.

Operation
The Audi Q5 hybrid comes with a new display concept, rendering the individual driving states of the hybrid drive clear-cut and tangible. Instead of the tachometer, the needle of the power meter in the dash panel insert indicates the total output of the system on a scale of 0 to 100 per cent. A second scale is divided into colored segments – their green and orange-colored sections show at a glance how the Q5 hybrid quattro is currently traveling – with a greater share of electrical power or combustion engine power. An additional instrument displays the charge level of the battery.

At the same time, the display of the driver information system and the large monitor of the MMI Navigation plus show the operating states and power flows in the hybrid system in elegant graphics with a three-dimensional effect. The MMI screen also displays differentiated consumption and recuperation statistics in easily understandable bar graphs.

The MMI Navigation plus is standard on the Audi Q5 hybrid quattro, and comes in the latest stage of evolution. The storage capacity of the hard drive is 60 GB, the menus can be selected via a state-of-the-art wizard, and the album tracks are displayed using the cover artwork. An external device such as a cell phone or player can be connected via Bluetooth, and the voice input understands town and street names in a single command. The resonant Audi sound system is also standard.

The quattro Drive and the Running Gear
The permanent four-wheel drive applies the power of both power units safely to the road in any situation. In the normal condition the sporty drive is emphasized at the rear; if need be, it transmits most of the power to the axle with the better traction. The sophisticated running gear includes many aluminum components for reduced weight. The Audi Q5 hybrid quattro may pull trailer loads of up to 2000 kg (4409 lb).

An electro-mechanical unit serves as the steering system, with a small electric motor generating the power. The system operates at high efficiency, since it need not consume any energy in straight-ahead driving. The brake servo is additionally supplied by an electric vacuum pump. A complex rule-based strategy adapts the braking to the conditions of electric driving and energy recuperation.
The Exterior
The Audi Q5 hybrid quattro is distinguished by visual features on the outside. The tailgate, the fenders and the aluminum sill panel strips bear the hybrid lettering. The radiator grill is glossy black, and the tailpipes chrome-trimmed. Polar Silver, metallic is available for the exclusive paintwork.

The 19 inch cast aluminum wheels were specially designed for the hybrid – their ten spokes resemble turbine blades. The tires are size 235/55. On request Audi supplies other wheels with 19 and 20 inch diagonals, with an S-line bumper available from quattro GmbH.

The body is unusually light in weight; the tailgate and the engine hood are aluminum. The rigid body shell incorporates hot-stamped steel at numerous places, combining low weight with very high strength.

Despite the generous level of standard equipment, the Q5 hybrid quattro with its curb weight of less than 2000 kg (4409 lb) is the lightest hybrid SUV on the world market. All its hybrid components add less than 130 kg (286.60 lb) extra weight.

The Equipment
The climate control system of the Audi Q5 hybrid was adapted to the requirements of electric driving. The compressor of the air conditioning has a high-voltage based electric drive; demand-controlled for high efficiency, the compressor ensures AC operation even when the combustion engine is shut down. An electric auxiliary heater supports the interior heating.


The Audi Q5 hybrid quattro offers almost the same equipment as its successful sister models – the model series leads the European market in the mid-sized SUV segment. The options also include sophisticated driver assistance systems. A new feature is connection to the internet via the optional Bluetooth car phone online. A UMTS model sets up the connection to special services from Google and the World Wide Web, bringing the latest news and weather information into the vehicle.

The driver can plan his or her travel route at home, save the information in an area of the internet site www.audi.com and from there download the data into the navigation system via UMTS at the start of the trip. Through the fast connection the hybrid SUV also downloads three-dimensional satellite images and aerial photos from Google Earth. They appear as bird's eye views on the monitor; the computer draws in the roads.

Another high-end feature is the WLAN hotspot, allowing connection to the internet via up to eight terminal devices. Communication occurs via the roof antenna, the connection is very stable and the reception quality excellent. Thanks to a special modulation process, UMTS data transfer occurs at speeds up to 7.2 MB per second. Encryption follows the WPA 2 standard – a very secure method.

The use of the WLAN hotspots is as easy as can be – the driver need merely insert a data-capable SIM card. At the same time the driver can pair a cell phone with the system via Bluetooth, if the phone has the SIM Access Profile. The existing mobile phone contract with a data option suffices in most cases with the result that no additional charges or separate contracts are necessary.

The Audi Q5 hybrid quattro will arrive at dealerships during 2011

Audi Q5 hybrid quattro: First details and videos emerge

Audi has unexpectedly released the first details of the highly anticipated Q5 hybrid quattro today. In a rather unusual fashion, the Q5 hybrid was revealed through Audi's various regional websites (audi.de, audi.co.uk, audi.fr etc), rather than being first posted to Audi Media Services (Audi's press website). We imagine more in-depth coverage will be available soon, including full press release and hi-res photos. But until then, this is what we know so far (including two videos).



The Audi Q5 hybrid quattro makes use of both a 2.0 TFSI gasoline engine and 33 kW (44hp) electric motor mated to a 8-speed tiptronic integrated hybrid transmission. Combing the electric and gasoline motors results in 241 horsepower and 354 lb-ft of torque, which enough to accelerate the Q5 hybrid from 0-62mph in 7.1 seconds on to a top speed of 138 mph. While power and straight-line performance is very impressive for a hybrid crossover SUV, it's also noted that the Q5 hybrid quattro is capable of driving up to two miles at 62 mph on the electric motor alone.



Audi explains that the Q5 hybrid quattro can be driven in three different modes: EV, D and S. When driving in EV-mode, power is focused almost entirely on the vehicle's 33 kW electric motor. D-mode offers a more efficient blend, deriving power equally between both the electric motor and the 2.0 TFSI gasoline engine. Finally, as it's letter designation implies, S-mode is the sport option, combining maximum power from both powerplants. The video above this paragraph delves deeper into these driving characteristics, however it's currently available in German only (those who do not speak German should still watch though, you'll be surprised at what you can pick up).





We expect more details to be released shortly, as the Q5 hybrid quattro is rumored to make its official debut at the 2010 LA Auto Show next week. In the meantime, check out the Q5 hybrid features at Audi.de and Audi.co.uk
