Introduction Audi future

Audi future engines

The combustion engine will to assume primary importance in the for a long time. TDI and TFSI are the classic pillars of the brand the four rings, and it is further its leadership position with In recent years, Audi in making great progress in of these technical areas; over 100 model versions less than 140 g/km of CO2 g/mile), and 33 versions even less than 120 g/km g/mile).

Further considerable potential will be tapped in the as well without detracting the emotion-packed driving experience.

A example of Audi’s innovative is the electrically boosted turbocharger for TDI the electric biturbo. Among engines, rightsizing will crucial importance in the future. concept refers to a bundle of technologies for optimizing gasoline that target a 15 percent in fuel consumption over the several years. The predictive assistant offers further

The intelligent use of navigation data it possible to coast the car longer, to shut off the engine in an anticipatory way.

A third cornerstone of mobility is electrification of the powertrain. The new models the A6 hybrid, A8 hybrid and Q5 quattro are already on the streets They impress with high efficiency and their driving range of up to three (1.86 miles).

The next step will be cars can cover longer distances in electric mode and can be charged an electrical outlet the e-tron Audi is simultaneously branching out in directions: from the city with range extender to the plug-in hybrid (Dual-Mode and finally the purely electric-powered R8 e-tron high-performance sports which will make its on the streets at the end of this year.

For electrification is a crucial technology the with the four rings is and reinterpreting its motto Vorsprung Technik here. Engineers are intensively on all aspects of the technology They include new types of storage technologies, intelligent strategies and an electrified all-wheel vehicle the e-tron quattro, the concept vehicle implemented in the e research project.

The goal is to uncompromising vehicle concepts offer maximum utility and all of the brand’s strengths. Fascination and will define the character of Audi vehicles as well. The with the four rings already be offering its first hybrid models starting in Over the mid-term, e-tron will grow to become one of the pillars of the company.

By the year Audi wants to be the leading manufacturer of electric vehicles.

today, the brand has already demonstrating the dynamic potential of the drive with the world of the R8 e-tron on the North Loop of the race course and with the victory of the R18 e-tron quattro at the 24 of Le Mans. Future drive at Audi will be sustainable and efficient as well as very and dynamic.

Rightsizing strategy at Audi

has made great progress in the of its TFSI gasoline engines in years. However, considerable potential continues to exist. engineers plan to tap this with a series of new technologies will be implemented under the concept.

For many years Audi has been a pioneer of in gasoline engines. At the end of the 1970s, the gasoline engine with already made its debut a five-cylinder unit. The next milestone was the 1.8-liter four-cylinder in 1995.

In 2004, the brand the four rings rose to the top of the field with the world of TFSI technology that charging and gasoline direct

The strategy of downsizing replacing displacement by charging led to large in torque. This let developers downspeeding, i.e. the use of transmissions fuel-saving long gear Audi is still pursuing successful course today, and now are its key competitors following suit.

The engine series with code EA888, which its debut in 2006, marked advance in TFSI technology. In its development stage, now its third, the and 2.0-liter TFSI engines are now with a large bundle of solutions. They include the valvelift system (AVS), of the exhaust manifold in the cylinder turbocharger with electric control, an innovative thermal system with an electric regulator and a dual fuel-injection that combines direct with injection into the manifold.

Altogether, these lead to some very results. In the A4 with a manual the 1.8 TFSI with 125 kW (170 hp) has a fuel consumption of just 5.7 per 100 km (41.27 US mpg) which to CO2 emissions of 134 grams per km (215.65 The A4 of model year 2000 a 1.8 T engine that produced 110 kW hp) of power was still emitting 197 CO2 per km (317.04 g/mile).

Improvements contributing to this fuel economy come many areas. However, primarily involve engine

The latest innovation from increases efficiency noticeably the on demand system. In the new 4.0 TFSI and 1.4 engines, four or two cylinders are down at part-load. This is aspect of rightsizing.

It aims for the ratio of engine displacement to at all times.

A central work of rightsizing is advanced development of charging. Audi developers want to further optimize and its dynamic buildup in the lower speed range. Very approaches already exist

Two-stage charging concepts, for offer distinct performance Materials used in the turbochargers now high temperature-resistant steel and turbine wheels made of

The use of new combustion methods is another key in advanced development of engine technology, especially in efforts to charge pressure. Especially in this context are low-pressure gas recirculation and the Miller and Atkinson which enable a longer phase. Both of these significantly boost efficiency mid- to high-load conditions.

At the end of the load spectrum, homogeneous compression ignition (HCCI), combustion methods and variable drives offer potential new to further boost efficiency.

In future fuels such as e-gas and e-ethanol play a role. Their use promises potential on the path towards mobility. The classic areas of friction, engine materials and management round out the work of engine developers.

Audi’s use of new technologies will once significantly improve the fuel of TFSI engines its magnitude be a full 15 percent by 2020. The of the brand with the four is to offer a mid-class sedan a TFSI engine that less than 100 grams of CO2 per km g/mile) by the end of the decade.

Electric from Audi


Audi is another big step forward the electric biturbo. In this technology, a secondary compressor the main turbocharger at lower speeds.

Nearly a quarter ago, Audi provided a impetus to international diesel in 1989, the first diesel direct fuel injection, and electronic control made its in the Audi 100. Since the TDI has enjoyed remarkable success.

makes a lot of sense especially in with diesel engines. It performance and substantially reduces consumption and emissions this downsizing par excellence compared naturally aspirated engines. to their displacement, TDI engines realized power gains of 100 percent and torque gains of 70 since 1989.

Over the time period, emissions been reduced by 95 percent.

The development stage from is a biturbo version of the 3.0 TDI it has a power of 230 kW (313 hp) and a maximum torque of 650 Nm lb-ft) between 1,450 and rpm. Its specific power is 77.5 kW (105.5 hp) per liter However, its combined fuel in the A6 is only 6.4 liters of fuel per 100 km US mpg), equivalent to CO2 emissions of 169 per km (271.98 g/mile).

What all engines have in common is the turbocharger is driven by energy the exhaust. This means starting from very low the rise in boost pressure and torque becomes gradually only as the exhaust energy

A new development stage is the electric This makes it possible of the exhaust energy available to up charge pressure quickly and high levels of torque at very low revs.

In advanced development at Audi’s site in a 3.0 V6 TDI was built and calibrated with an biturbo. It is a combination of a conventional turbocharger with a secondary driven compressor whose appearance is almost identical to of a conventional turbocharger.

Instead of a wheel driven by the exhaust gas this is an auxiliary charging arranged in line with the turbocharger. It integrates a small motor that can accelerate its to very high speeds in an short time. The electrically compressor is placed after the turbocharger and intercooler in the charge air In most operating states, the air is routed around it via a bypass.

when the flap integrated in the closes i.e. when the turbocharger’s energy output is low the air is into the electric compressor and is there a second time.

The of the new concept are impressive. Torque occurs significantly earlier in drive-off, which the driver as a distinct boost in performance.

The required to drive the electric is largely offset by battery during coasting phases, so the end effect is essentially neutral regard to energy consumption.

The and compact charge air path two-stage turbocharging with one turbine that is driven by gas. The reduced heat enables earlier activation of the converter.

The predictive efficiency from Audi

Audi is new, intelligent solutions in to further reduce fuel One of these is the predictive efficiency (PEA) it uses route from the navigation system and the surround sensors to promote a style of driving and so lower the of fuel used by the customer.

limit or place-name signs a curve or over a hill force the driver to brake However, braking in conventional involves the conversion of kinetic into heat. It would be more efficient if the driver step off the gas early on and steadily towards the speed limit.

To this possible, we need to be to identify what is lying as accurately as possible, i.e. such as bends, traffic and road conditions.

This is the focus of the predictive efficiency (PEA), a pre-development project Audi: the objective is to use route provided by the navigation system route data for drivetrain In addition to fixed speed the new major development stage of the MMI plus system also gradient data.

The drivetrain management system can use information to decide whether it is to drive the route with the connected or disconnected. The PEA also into account changes in mass or additionally attached such as roof boxes, racks or trailers. The system is by the adaptive cruise control which monitors traffic in of the vehicle using a radar

The efficiency assistant informs the at the pre-calculated moment that now is a time to start coasting. takes him or her comfortably and without following traffic to the next a speed limit, for example. The can be given in the form of a message in the information display or as a haptic such as a vibration in the gas pedal.

the driver can use the functions in conjunction the adaptive cruise control. In case, coasting periods are independently, allowing the vehicle to the required speed for speed zones or bends. Comfort and are ideally intertwined.

The information the driver to adopt a more driving style and therefore to reduce actual consumption. on the model and the equipment fitted, the may coast with an engaged fuel cut-off) or disengaged drivetrain. In both cases, the engine is still running.

In a development stage, it will be to switch off the combustion engine if the is disengaged (freewheel engine

When the gas pedal is released, vehicles respond by activating fuel cut-off. However, the models in the A6, A8 and Q5 model series coast without engine torque even if the driver off the gas at higher speeds the drivetrain is and the engine is switched off. the electric motor brakes to recharge the lithium-ion battery and to typical deceleration behavior.

The function on the S tronic, available in with some engine for the Q3 and A3, has a similar effect. Depending on and transmission configuration, the freewheel saves more fuel conventional overrun fuel especially when the freewheel takes place over as a distance as possible while the road ahead.

In order to efficiency even further in vehicles, the predictive efficiency can be combined with the iHEV When the freewheel function is the internal combustion engine is off (freewheel engine off). The is performed by a powerful 48V electric which is located in the belt

While the engine is switched energy is supplied via a high-cycle-strength 48V battery.

Together with the efficiency assistant, iHEV can unleash their full potential, as comparative test in a vehicle with the new technology shown. The A7 Sportback 3.0 TFSI several times completed a 61 km mile) stretch of winding roads north of Ingolstadt, a normal, everyday style of

During the tests without the efficiency assistant, the driver 28 percent of the route with the switched off. With assistance, this figure to 43 percent; at the same time, consumption dropped by around ten yet the driving time increased by two minutes (three percent) a neutral impact.

In future, the functions of Audi connect ensure that the data is always up to date. If an Audi identifies a traffic sign a speed restriction using its camera at recently started for instance it will send the and speed limit via the cell network to a server in the Audi IT From there, following a check, the information will be to all suitably equipped vehicles subsequently drive along the route a concrete example of the car-to-X-technology, which the brand is on intensively.

Audi electrification

Audi e-tron

At Audi, the e-tron refers to all cars can cover longer distances on electric power. By 2020, the with the four rings to offer an e-tron model in segment. Together, they achieve an annual sales in the six-figure range. Today are already various test featuring the new technology.

At the end of the year, a production R8 e-tron model hit the road.

Audi is working on all of electric mobility with the aim of the varying demands of customers The resulting concepts offer benefits without compromise innovative ideas and with progressive and sophisticated automobiles convey all the qualities of the brand. and emotion will also the character of an electrically powered

Audi’s wide-ranging electrification incorporates all the relevant concepts. One of is the electrically powered high-performance car, the R8 e‑tron, a limited model that will hit the towards the end of the year.

At the same the brand’s engineers have test cars that various approaches to the new technology, as the Audi A3 e-tron concept. as a parallel plug-in hybrid, it go into series production in The Q7 and A4 with plug-in hybrid will follow a short later.

An alternative to the parallel concept involves splitting the of the combustion engine and the electric between the axles. The e-tron study based on the Audi A5 this approach. Two electric complement the 2.0 TFSI one is mounted at the axle, the other at the rear.

The prototype R18 e-tron quattro, the of the 24 Hours of Le Mans, follows a concept. A centrally mounted V6 TDI a capacity of 3.7 liters delivers a 275 kW (510 hp) to the rear wheels. The wheels can be driven for a short on electric power, with 75 kW hp) per wheel.

The energy, which is recovered braking maneuvers, is provided by a accumulator.

The compact A1 e-tron, on the hand, is a specialist for the urban and comes with an additional extender. Its electric motor drives the front wheels 75 kW of peak power; the range in mode is around 50 km (31.07 A rotary engine at the rear, displaces 254 cc and produces 15 kW of electric makes trips of up to 250 km (155.34 in total possible by recharging the 12 kWh via an alternator.

Audi has conducted an fleet test with the A1 e-tron models in Munich, which more than km (31,069 miles) have covered to date.

The test of two phases. The first involved a of drivers who were able to the car at public charging stations and at place of work. In the second it focused on users who could the A1 e-tron via a wall box at home.

to both, a pilot phase place in which Audi every participant with an A1 1.4 as a reference vehicle to enable comparisons to be made between a gasoline and electric-powered car.

The test will be completed at the end of Important results on customers’ behavior, the charging infrastructure and the performance are already available.

At the of the test, according to the findings, the of the A1 e‑tron users first and had to learn how to maximize the driving of the electric car. However, managed to do so quickly; many took trips out onto the and far beyond Munich’s city they did not use the A1 e-tron any differently the A1 1.4 TFSI they had driven After a short time, the were very happy the electrically powered compact car and the feel it provided; they saw as trendsetters for a new form of mobility.

the course of the test, the distances on electric power rose 76 to 91 percent, shifting the energy mix to a cost-effective level.

The sustainably green electricity, which the Audi A1 e-tron models in the area, and the low amount of fuel was required to run the range extender, out at between four and seven per 100 km (62.14 miles), depending on the driving profile.

Audi continue its tests with the A1 the company is taking part in a called Schaufenster Elektromobilität, a for electric mobility, which at the beginning of 2013 and is funded by the Ministry of Education and Research. The with the four rings be involved in the model regions of Berlin-Brandenburg and Baden-Württemberg, and will on various themes in each

The holistic approach that is adopting in the field of electric includes another promising the Dual-Mode Hybrid technology. At the project is at the pre-development stage: have begun with the prototypes based on the A1. The layout of the system essentially comprises a engine, two electric motors and a transmission.

The combustion engine is a developed three-cylinder TFSI a capacity of 1.5 liters, based on the four-cylinder version. It generates 95 kW hp) of power and 200 Nm (147.51 lb-ft) of The three-cylinder unit is combined an electric motor (EM 1), which functions as a starter and alternator.

It a peak output of 50 kW (68 hp) and a maximum of 210 Nm.

The electric traction is provided by the electric motor (EM 2) in the drivetrain; it a peak output of 85 kW (116 hp) and a torque of 250 Nm (184.39 lb-ft). The streamlined single-speed transmission the combustion engine, including the to be engaged or disengaged as required the rest of the drivetrain by means of a clutch.

The Dual-Mode Hybrid allows various operating In the urban speed range standstill and 55 km/h (34.18 the vehicle is driven exclusively by motor 2 (electric mode), the energy coming primarily the traction battery. In addition, a mode is available.

In this the combustion engine and the alternator (EM 1) electrical energy to support, or substitute the battery should it be

The electric mode is possible up to 130 (80.78 mph). From a of around 55 km/h (34.18 the drive system permits the engine and the alternator (EM1) to be coupled with the drivetrain operation offers the flexibility of the drive units to maximize or performance. Above 130 km/h mph), the vehicle is driven by the combustion engine.

If required for to reduce fuel consumption or to raise system performance motor EM 1 can support the three-cylinder

In addition to the operating modes which are selected by the drive system according to each the driver can choose an economical or setting; when driving at speeds, he/she can also the electric mode via an EV button. of operating mode, the driving is similar to that of a battery vehicle the driver does not any gear changes or notice the or motors cutting in.

Hybrid technology Audi

Audi is one of the leading producers of hybrid technology. The with the four rings full hybrid cars advanced lithium-ion technology in the B, C and D the Q5 hybrid quattro, A6 hybrid and A8 All three models are configured as hybrids that combine the of a six-cylinder engine with the economy of a four-cylinder.

The parallel hybrid powertrain Audi is a straight-line concept high efficiency and a modular The only difference between the hybrid models is that the Q5 quattro drives all four while the power in the sedans is directed to the front wheels. power is a uniform 180 kW (245 while system torque is 480 Nm

lb-ft).

Propulsion is provided by a 2.0 developing 155 kW (211 hp) and an electric developing up to 40 kW of power and 210 Nm (154.89 of torque. Power transmission is by a highly modified eight-speed which operates without a converter. Taking its place is a electric motor that is with a multiplate clutch.

It and disengages the electric motor and the they operate precisely, and fast in all situations.

A lithium-ion system serves as the electrical device. Weighing just kg (80.91 lb), it supplies 1.3 kWh of energy and has a power output of 39 kW. It is in two different ways as needed by a from the car’s interior and by a circulation loop that is to the deluxe automatic climate system. This technology the battery within a suitable window over a broad of conditions.

This assures a long electric driving of up to three kilometers (1.86 at a constant speed of 60 km/h mph). The peak speed of 100 (62.14 mph) in electric also sets standards.

and lightweight power electronics, are water-cooled like the electric convert the direct current the battery into alternating The power electronics integrate a converter that couples consumers in the 12-Volt electrical to the high-voltage network.

The brake is also supplied via an electric pump. A complex control adapts braking processes to the of electric driving and energy (battery regeneration). The air conditioning has an electric drive; an electric heater completes the climate system.

In total, the hybrid-specific represent less than 130 kg lb) of additional weight.

The performance of the hybrid models is as impressive as efficiency. They handle the from zero to 100 km/h mph) in between 7.1 and 7.7 seconds, and top speeds are between 225 and 240 km/h and 149.13 mph). Combined consumption is only 6.2 to 6.9 liters per 100 km to 34.09 US mpg) with CO2 of 145 to 159 grams per km (233.35 to 255.89

The hybrid models from can be driven with just the combustion engine, just the drive or in hybrid mode; can also regenerate the battery and boost. The driver selects one of programs: the EV mode prioritizes driving, the D mode controls power sources efficiently, and the S is configured for a sporty style of

The most important gauge is the in the instrument cluster. Its needle the total system power in over a scale from to 100. Another instrument the battery’s charge state.

In the color display of the driver system and the monitor of the MMI navigation system show power paths and operating states in graphics.

Audi can look on over 20 years of experience in technology. The first generation of the duo made its debut early on, in this was a technology concept car on the Audi 100 Avant. A five-cylinder engine powered the front while a connectable electric developing 9 kW drove the rear

Nickel-cadmium batteries served as the source. This was followed two later by another duo variant on an Audi 100 Avant quattro.

In Audi became the first carmaker to build a hybrid in a limited production run the Audi duo on the A4 Avant. Its drive power was by a 1.9-liter TDI developing 66 kW (90 hp) and an electric developing 21 kW, which was supplied by a gel battery at the rear. Both sources drove the front

Like the two concept cars it, the limited production car was also a hybrid its battery could be from an electrical outlet, and the motor recovered energy braking. The Audi duo reached a top of 80 km/h (49.71 mph) in mode and 170 km/h (105.63 with the TDI engine.

e performance

The F12 from the e performance research

Audi is systematically working out all of electric mobility from the up. The e performance research project a tank within the company has a modular component system for powered vehicles. This has in a sporty research vehicle, the in the framework of a research project by the German Federal Ministry of and Research (BMBF).

In its exterior the F12 research vehicle resembles the R8 e-tron, which will on streets at the end of this year. The R8 sports car with its lightweight Audi Space Frame served as the starting point for projects. The research vehicle, weighs around 1,650 kg lb), also attains performance values. It accelerates zero to 100 km/h (62.14 in less than seven

Its top speed is electronically limited to 180 (111.85 mph), and its driving is around 200 km (124.27 miles).

working on the e performance research took entirely new approaches to the drive technology. They not concerned with the production of the car, but rather with a broad-based and comprehensive approach to its Key components of the F12, all custom parts, can be interchanged with effort to enable many new

The system matrix is scalable engineers make suitable to the parts they can also be to configure a sedan or a city car an electric or plug-in hybrid

Two large, separately housed blocks with a total capacity of 38.9 kWh serve as the energy storage devices. The battery block is longitudinally in the center tunnel that was adapted for this purpose, and the block is mounted transversely in of the rear axle. The liquid-cooled weigh around 400 kg (881.85 they consist of a total of cylindrical lithium-ion cells of the commonly used in consumer

Each set of 26 cells forms a module; they are embedded in a high-strength structural foam and are by aluminum profiles integrated in the as well. The modules can be shifted to one another with their slanted walls. This the basis for the safety design according to calculations, can withstand a side impact.

The rear is installed in an ultra-lightweight pan made of fiber reinforced polymer

Three electric motors of types work together to the research vehicle. Each wheel is coupled to an asynchronous via a single-stage gearbox; each outputs 50 kW of power and 200 Nm (147.51 of torque. An intelligent control distributes drive forces on demand this torque makes handling even stable and sporty.

A synchronous is installed in the front section of the it delivers its 50 kW and 150 Nm (110.63 lb-ft) to a developed mechanically locking via a two-stage gearbox so the F12 is a fully quattro.

The three motors can be separately to utilize energy as as possible. During slow only the synchronous motor is it achieves a very high of efficiency. At higher speeds, the asynchronous motors come play at the rear axle.

innovation in the F12 is the switchable high-voltage system. Following the basic of scalability, the two batteries can produce output voltages at either 148 or 222 A high-performance direct current (DC/DC) regulates the desired system voltage.

Under the voltage is around 200 volts to efficiency; with increasing demand, it can be boosted up to 440 volts.

The development team of the e performance project targeted a maximum of integration in designing the control With this goal in they utilized valves to those used in building for the heat pump that thermal management of the drive and the interior. In many situations, the pump is used to heat up the this heat is stored and is to heat the interior on the next

The driver of the F12 controls basic functions P, R, N and D by operating buttons on the tunnel. An iPad in a mounting on the center console is used to all other operating steps, the degree of energy recovery and for the synthetic e-Sound. When the arrives at his or her destination, the iPad can be and used to configure the car remotely.

A instrument cluster displays all information in virtual digital with very high and quality.

The F12 research vehicle was as part of a three-year research sponsored by the German Federal of Education and Research. The project was 36 million euros. Engineers Audi, its subsidiary Audi Venture GmbH (AEV) and from the ika, ISEA and IEM of the RWTH Aachen university the core team of the e performance project.

Other external from the technical universities in Dresden and Ilmenau, Hanover’s University and the Fraunhofer IISB and institutes provided scientific Key industrial partners involved in the were Robert Bosch and Bosch Engineering GmbH.

The e research project has the freedom to entirely new approaches. Advanced tools and a new type of knowledge helped to create an atmosphere by engineering ingenuity, creativity, discussions and flexible networking. document every step in and all findings flowed via a ticket onto a server that was to all participants across Germany.

high level of transparency and based on the principle of open allowed the research project to a very positive influence on entire higher education and industry. Partnerships are continuing after completion of the F12 the first projects that focus on technical issues have begun. Individual solutions, as the CFRP housing for the rear show good prospects for production use.

The Audi R8

To Audi, electric mobility emotion, sportiness and driving a principle that has been demonstrated by the Audi R8 e-tron. On the Nordschleife in June, it achieved a time for a production vehicle an electric drive system. driver Markus Winkelhock the car around the 20.832-kilometer track miles) in 8:09.099 minutes.

The drives were a fantastic for me, said a beaming Markus after the event. The 32-year old Swabia has a high standard for the Audi R8 LMS ultra, in which he, with Marc Basseng, Haase and Frank Stippler, won the race at the Nürburgring in May 2012.

The system of the record-setting vehicle in every detail to the production that will hit the road at the end of the Its ultra-light body primarily of aluminum based on the ASF construction (Audi Space Frame) as as CFRP components; it is the main why the high-performance sports car has a curb of just 1,780 kilograms lbs), despite the hefty

Together, the two electric motors in the R8 transmit 280 kW (381 hp) of power and 820 Nm of to the rear wheels. They can be individually, which enables torque vectoring torque depending on the driving situation. The R8 sprints from zero to 100 (62.14 mph) in 4.6 seconds; its top is normally limited to 200 km/h mph).

For the record-setting lap, completed by the sports car on cup tires, a speed of 250 (155.34 mph) was approved.

The lithium-ion battery is mounted in the center tunnel, in front of the axle. The 48.6 KWh of energy it is enough for a distance of around 215 (133.59 miles) of everyday On the extremely tough Nürburgring where a conventional high-performance car can use up to 65 of gasoline per 100 km (3.62 US mpg), the power was sufficient for two fast in succession.

The energy recovery proved to be useful here the vehicle decelerates, the electric act as powerful alternators that most of the load off the electromechanical at the rear wheels.

In addition to the single lap on the Nordschleife, the R8 e-tron with Markus Winkelhock at the — also set an impressive for two back-to-back laps. Limited to 200 (124.27 mph) and equipped standard tires, it completed the in 16:56.966 minutes.

The R8 e-tron is a car, of course, with no aids, said Winkelhock. But its low center of gravity and rear-biased distribution it has a lot of sporty qualities. The with which the electric propel the car out of tight bends is even if they hardly any noise in the process, which was a completely new experience for me.

The Audi R18 quattro

The e-tron technology Audi offers fascinating In June, the sports prototype the R18 e-tron quattro — won the race at Le Mans with an specially developed hybrid

The Audi R18 e-tron quattro is a concept packed with technology. With it, Audi has a drive technology never seen in motor sport. At the axle, a 3.7-liter V6 TDI engine more than 375 kW (510 hp) and than 850 Nm (626.93 ib-ft) of provides powerful and efficient

A six-speed transmission made of carbon fiber reinforced (CFRP) transmits the power to the

At the front axle sits the motor generator unit developed by Audi in conjunction its system partners. A generator and a transform energy recovered braking phases into current; this powers a accumulator, which is located in the next to the driver. The electricity an ultra-light CFRP flywheel, runs in a vacuum, to up to 45,000

When exiting the bend, the can retrieve the energy from the It then supplies the MGU’s two motors that drive the wheels with up to 150 kW (204 hp) of for a short time the Audi R18 TDI is a with four driven So that this did not become too of an advantage, the organizers of the 24-hour Le race restricted the use of the MGU to the speed above 120 km/h (74.56 to a maximum of 500 kilojoules of energy and to zones on the circuit.
