Quattro Unveiled at Audi TechTalk

In the “Audi TechTalk” program, which Audi handles issues related to automotive technology and held in an online meeting format, the new topic was quattro due to its 40th anniversary.

Audi TechTalk continues to focus on automotive technologies. Quattro was the subject of the last part of AudiTechTalk, which was held in online format, where Audi experts convey information about the technologies used by Audi and answered questions.

In the first episode of Audi TechTalk, Plug-in Hybrid technology was explained. The approach that Plug-in hybrid models, which is an ideal solution for low emission and long-distance travels, and modern mobility are at odds with each other, was explained. In the second part, Audi engineers' journey of technology from a classic air suspension to the connected driving dynamics computer was transferred.

Audi TechTalk has included this technology in the last part of the 40th anniversary of quattro.

4 rings, 4 wheel drive, 4 times aster: quattro

Quattro, which has become a success story not only for Audi but also in the automotive world with a production of approximately 1980 million units since 11, has become synonymous with the Audi brand today. The quattro, which stands apart among all-wheel drive technologies, has continued to evolve since its debut at the Geneva Motor Show in 1980. And today it has become an electric quattro with electric torque vectoring.

Quattro 2.0 in the electric age

In 2019, with its e-tron and e-tron Sportback models, Audi entered the world of electric mobility quickly, and also entered the world of electric four-wheel drive. As is known, electric motors drive the front and rear axles in both SUV models. The suspension and drive control units likewise work closely together to regulate the ideal distribution of drive torque.

In early 2020, Audi developed the Audi e-tron S and Audi e-tron S Sportback models, this time with electric torque vectoring, each with rear wheels driven by separate engines. The extremely high torque provided in these models kicks in in just milliseconds, allowing the car to take corners as dynamically as a sports car, making Audi the first manufacturer in the premium segment to massively produce the technology using three electric motors.

40-year quattro: milestones

When the Audi quattro first appeared at the Geneva Motor Show in 1980, it introduced a completely new method of power transmission in the passenger car industry - a lightweight, compact, efficient and low-tension all-wheel drive system. This feature made the quattro suitable for fast, sporty cars and, of course, high-volume models from this date.

The 147 kW (200 PS) original quattro remained a standard model until 1991 as part of the range and underwent several technical revisions. In 1984, Audi added the special "short" Sport quattro with a power output of 225 kW (306 PS) to its model range. With the introduction of the Audi 1986 quattro in 80, the differential, which until then could only be locked manually, was replaced by a self-locking differential for the first time, achieving a fully mechanical 50:50 distribution of torque between the front and arc axles.

The brand continued to develop quattro technology in the following years. The first diesel with permanent all-wheel drive, the Audi A6 2.5 TDI, was launched in 1995. In 1999, quattro technology in the form of an electro-hydraulic clutch was introduced in the A3 and TT model series and therefore in the compact segment with transverse engine configurations. The next big step came in 2005; differential that distributes dynamic power asymmetrically between the front and rear axles in a ratio of 40:60. With the first Audi R2007 in 8, a viscous link on the front axle, followed by a rear axle sports differential, was introduced a year later. In 2016, the ultra-tech quattro optimized for efficiency was added to the range, and Audi introduced the electric all-wheel drive with the e-tron in 2019.

40-year quattro: supremacy in motorsport

quattro also played a major role in Audi's mark on the world of motorsport. World Rally Championship - Audi joined the WRC in 1981 for the first time, and thanks to quattro, it became the dominant brand of the championship a season later: the Audi team won the Manufacturers 'title in 1982, and the Finnish driver Hannu Mikkola became the Drivers' Champion a year later. Audi won the championship in both categories, with Swedish Stig Blomqvist being the world champion in 1984. That year, Audi first used the Sport quattro with a short wheelbase and then included the Sport quattro S1985, which produced 350 kW (476 PS) in 1, to the parks. Two years later in 1987, Walter Röhrl led a specially modified S1 to victory on Pikes Peak hill climb in the USA.

A technology that's forbidden

Audi then began to appear in Touring races. Having won both the drivers and manufacturers championship in the US Trans-Am in 1988 in its first attempt with the Audi 200, Audi achieved a significant success in the IMSA GTO series the following year. In 1990/91, Audi won two Drivers' Championships at the Deutsche Tourenwagenmeisterschaft (DTM) with its powerful V8 quattro. A4 quattro Supertouring entered 1996 national championships in 7 and won them all. Two years later, European motorsport organizers banned all-wheel drive in almost all touring car racing.

When the years showed 2012, a racing car with quattro technology hit the tracks: the hybrid Audi R18 e-tron quattro. In the car, a V6 TDI powers the rear wheels, while two electric motors using energy recovered by a flywheel accumulator power the front axles. Using a temporary quattro drive system during acceleration, the model won three victories in the 24 Hours of Le Mans series and twice the Drivers and Manufacturers category championship at the World Endurance Championship (WEC).

40-year quattro: Vorsprung durch Technik

The quattro, which has become an icon for Audi and even the automotive world, represents safe driving and sportiness, technical expertise and high performance. So Vorsprung durch Technik for Audi. The success of the quattro models on the road and in racing has been reinforced by a series of legendary TV commercials and advertising campaigns. Among the commercials that have been memorable to almost everyone, in 1986, professional rally driver Harald Demuth came out with an Audi 100 CS quattro to the Kaipola ski jumping hill in Finland. In 2005, Audi repeated this event, this time with an S6, on the same specially restored ski jumping track. In 2019, the track hosted the rallycross champion Mattias Ekström and his e-tron quattro.
