Over 40 years of quattro – over 40 years of Vorsprung durch Technik
In 2010, the Audi quattro concept – a re-interpretation of the original quattro – appeared at the Paris Motor Show. From 2015 on, numerous concept cars heralded the future arrival of standard e-tron models with electric all-wheel drive: the Audi e-tron quattro concept (IAA 2015), the Audi e-tron Sportback concept (Shanghai 2017), the Audi e-tron GT concept (Los Angeles 2018), and the Audi Q4 e-tron concept (Geneva 2019).

The track record
Audi has fueled the appeal of quattro again and again over 40 years with a succession of spectacular concept cars. The quattro Spyder, presented at the 1991 International Motor Show (IAA) in Frankfurt am Main, Germany, was the brand’s first thoroughbred sports car of the post-war era and its first aluminum-bodied car. Just a few weeks later, Audi presented the Avus quattro at the Tokyo Motor Show. It was designed to feature a W12 engine producing 374 kW (509 PS) mounted longitudinally ahead of the rear axle, the manual transmission in the quattro drivetrain positioned between the front wheels. The Audi TT quattro Coupé and Roadster concepts presented in fall 1995 indicated the way to series production. Three more concept cars marked the expansion of the model range in 2003. At the Detroit Motor Show in January, Audi presented its Pikes Peak quattro, the predecessor to the Q7. This was followed at the Geneva Motor Show by the Nuvolari quattro two-door coupé, which paved the way for the A5. Then, in September, the Audi Le Mans quattro was the star of the IAA in Frankfurt – and also the spitting image of what would later become the R8. The Audi R8 e-tron concept, one of the stars of the IAA in 2009, was a sports car with electric-only drives at all four wheels. In 2010, the Audi quattro concept – a re-interpretation of the original quattro – appeared at the Paris Motor Show. From 2015 on, numerous concept cars heralded the future arrival of standard e-tron models with electric all-wheel drive: the Audi e-tron quattro concept (IAA 2015), the Audi e-tron Sportback concept (Shanghai 2017), the Audi e-tron GT concept (Los Angeles 2018), and the Audi Q4 e-tron concept (Geneva 2019).

Pathway to production – e-mobility at Audi
Audi has already been developing models with all-electric or hybrid drive since the late 1980s. The first production offering of a car combining a combustion engine with an electric motor was the Audi duo from 1997, which occupied the body of an Audi A4 Avant. A landmark technological development for electric cars was the Audi R8 e‑tron, which was unveiled at the 2009 Frankfurt Motor Show and in 2012 set a record lap time for an electric car on the North Loop of the Nürburg Ring. Audi added a first plug-in hybrid to its range in 2014 in the guise of the 150 kW (204 hp) Audi A3 e‑tron – its battery units can be recharged by recuperation and cable, and give it an all-electric range of up to 50 kilometers in the NEDC. The Audi Q7 e‑tron made its debut in 2016 – it is powered by a combination of a 3.0 TDI and an electric motor which together deliver 275 kW (373 hp) and 700 Nm (516.3 lb ft) of torque. It accelerates from a standing start to 100 km/h (62.1 mph) in 6.2 seconds and is particularly efficient. In all-electric mode, it has a range of up to 56 kilometers (34.8 miles) while producing zero local emissions. It is also the world’s first plug-in hybrid with a V6 compression ignition engine and quattro drive. Another concept car unveiled by Audi in 2015, at the Frankfurt Motor Show, was the study vehicle called the e‑tron quattro concept – the forerunner of the brand’s first all-electric-drive production automobile. As a radically reconfigured SUV it offers a range of up to 500 kilometers (310.7 miles) with the spaciousness and comfort of a typical full-size automobile from Audi. It has the road performance of a high-performance sports car – the e-tron quattro sprints from 0 to 100 km/h (62.1 mph) in only 4.6 seconds. The production version of this pioneering electric SUV will appear on the market in 2018. The Audi e‑tron Sportback concept will be followed by its production version in 2019.
e-tron: Heading for the future on electric power
Progress feels electric: Audi commits to electric mobility – at the end of 2017 on the race track with a factory-backed team of its own in Formula E, and from 2018 onward with the e-tron and numerous other production models on the road. Audi has a clear vision for the future. As early as by 2025, one in three Audi cars delivered is planned to be an electric vehicle. Even before this date, the portfolio of the brand with the four rings will include more than 20 electric and plug-in hybrid vehicles – spread across all segments and all models. Motorsport, once again, is assuming a pioneering role in this context. For nearly 40 years, Audi has been active in motorsport on the highest level in order to test new technologies for production. quattro, TFSI, TDI and hybrid are now followed by e-tron. The Audi e-tron FE04 is the group’s first fully electric race car. “With our involvement in Formula E, we are also showing in motorsport what the transformation from an automobile manufacturer to a forward-thinking mobility provider looks like,” says Rupert Stadler, Chairman of the Board of Management of AUDI AG. “With our concept of sporty electric mobility we demonstrate Vorsprung durch Technik and show how much fun a driver will have in an electric automobile.” The first vehicle to be launched in 2018 will be the sporty Audi e-tron SUV, enabling a range of more than 500 kilometers. It will be followed in 2019 by a four-door grand tourer. In 2020, Audi will be extending its electric offering by a compact model. From 2021 on, all the core model ranges are planned to be electrified, including mild hybrid technology. Including the planned volume growth, a third of all Audi models will be electrified in 2025 – either fully electric or with a plug-in hybrid. Since as far back as the late 1980s, Audi has been developing models with fully electric or hybrid drive.

Innovations: From A to Z
Audi virtual cockpit curved OLED The Audi virtual cockpit curved OLED is the further development of the Audi virtual cockpit in the Audi TT, Audi Q7 and Audi R8. It is based on state-of-the-art OLED technology. For the first time ever in the automotive field, a curved, 14‑inch OLED display is being used as an instrument cluster. Audi Wireless Charging (AWC) The Audi e-tron is equipped with Audi Wireless Charging technology for contactless induction charging. A charging plate with an integrated spool is placed on the parking space and connected to the mains supply. Using its piloted parking system, the Audi e‑tron quattro concept positions iteself over the charging plate with pinpoint accuracy. The charging process then begins automatically. As soon as the battery is fully charged the process stops again. The Audi Wireless Charging technology is over 90% efficient, almost as effective as charging via a cable. The alternating field does not pose any risk to people or animals. It only builds up when a car is positioned above the induction charging plate. Battery technology The large battery of the Audi e‑tron quattro concept, just like the battery of the Audi R8 e‑tron, follows a basic modular concept. It is in principle also suitable for use in other models. Audi is using it for the first time in an SUV. The modular philosophy also means that Audi will always be able to use the best cell technology available on the market, regardless of whether prismatic, pouch or round cells. CCS The abbreviation “CCS” stands for combined charging system. Electrified cars with this plug system can be charged with both alternating current (AC) and direct current (DC). Power output is significantly higher when charging with direct current and the charging time correspondingly shorter because the electricity can flow directly into the battery without additional rectification.
