40 years, 40 figures, 40 images: fascinating contribution and tales about Audi’s quattro technology

0 clutches and differentials are during work in a Audi e-tron** and in a e-tron Sportback**. The entirely electric SUV models exercise electric all-wheel drive, whereby a electric motors exercise all quattro functions.

0.5 seconds is how distant forward a control section always calculates in a quattro with ultra technology. The intelligent open- and closed-loop control works predictively interjection to high-performance sensors and information evaluation. The quattro with ultra record uses dual clutches that concede it to switch from front-wheel expostulate to all-wheel expostulate in a blink of an eye. During assuage driving, a quattro with ultra record enjoys all a advantages of a fit front-wheel drive. All-wheel expostulate stays invariably accessible however, and is there immediately and even in allege when needed.

3 times in a row, a Audi R18 e-tron quattro won a Le Mans 24-hour competition between 2012 and 2014. A V6 TDI gathering a back wheels, while a flywheel accumulator granted recuperated appetite to dual electric motors on a front axle. As a result, a competition automobile was means to exercise this proxy quattro expostulate complement during acceleration.

3 electric motors supply propulsive energy in a new Audi e-tron S and Audi e-tron S Sportback – a universe initial in volume production. The dual electric motors on a back spindle capacitate electric torque vectoring, a need-based placement of propulsive energy to sold wheels on a left and right.

3.1 seconds is how prolonged it takes a Sport quattro S1 with a middle primer delivery ratio to accelerate from 0 to 100 km/h (62.1 mph). The convene automobile that Audi used for a initial time in 1985 constructed 350 kW (476 PS) with a five-cylinder turbo engine and weighed usually 1,090 kilograms (2403.0 lb).

4 conflicting all-wheel expostulate clutches and 4 conflicting core differentials are in use conflicting a whole Audi indication range. The self-locking core differential was designed for a models with longitudinally mounted front engines and eight-speed tiptronic. In some engine versions, it works with a sport differential on a back axle, that distributes a expostulate torques between a wheels depending on a pushing situation. In a models with longitudinally mounted engines, the seven-speed S tronic partners with a quattro with ultra technology, that uses dual clutches. In a compress Audi models with cross engines, a hydraulically tranquil multi-plate purchase takes charge, that sits on a back spindle for improved weight distribution. The R8 high-performance sports car also facilities a tranquil multi-plate clutch, though in this box it is positioned on a front axle.

5 kilograms (11.0 lb) was a estimate weight of initial self-locking Torsen core differential used in a strange Audi quattro in 1986. The simple placement was 50:50 between a front and back axles. Today, a self-locking Torsen core differential in a models with longitudinally mounted engines weighs usually around 3 kilograms (6.6 lbs) and has a simple placement of 40 percent to a front spindle and 60 percent ot he back axle.

6 mins and 29 seconds was a lead that Walter Röhrl hold over a runner-up during a Rallye Sanremo in 1985 with a Sport quattro S1. In a final competition of a season, a British RAC Rally, Röhrl used a dual-clutch delivery that was actuated pneumatically. A predecessor of today’s S tronic, it was a genuine initial during a time. Today’s electronic possibilities are what make a potency and functionality of a complicated dual-clutch delivery and a active formation in a altogether tuning of a automobile possible.

10 mins and 47.85 seconds was a time with that Röhrl triumphed with a Audi Sport quattro S1 during a Pikes Peak Hill Climb (USA) in 1987. In a fastest partial of a 20-kilometer march (12.4 mi) with an altitude of 1435 meters (4,708 ft), an normal slip of seven percent and 156 bends, he was totalled roving during a speed of 196 km/h (121.8 mph).

11 degrees was a steering angle a engineers chose for a back wheels in an initial all-wheel steering pattern in a quattro antecedent in 1984. Today, tip Audi models such as a RS 6 Avant are versed with dynamic all-wheel steering on request. At low speeds, it turns a back wheels a limit of 5 degrees in a conflicting instruction to make maneuvering and parking easier, for example. At aloft speeds, it turns them adult to 2 degrees in a same instruction in sequence to boost fortitude when changing lanes quickly, for example.

12 engineers assisted plan manager Walter Treser in a growth of a initial Audi with permanent quattro expostulate from Feb 1977.

16 array constructed by a code with a 4 rings are accessible with a quattro expostulate and 10 of them are constructed in Germany.

23 races were won by quattro drivers Michèle Mouton, Hannu Mikkola, Stig Blomqvist and Walter Röhrl in a Rally World Championship with Audi in a 5 years from 1981 to 1985. As a result, Audi was means to applaud a supremacy of a quattro element in rallying.

30milliseconds is how prolonged it takes for a Audi e-tron and e-tron Sportback to change torque from a back spindle to a front axle. It takes 3 times as prolonged for a tellurian to blink. No automatic purchase is intent with the electric all-wheel drive; instead, electricity is simply distributed – and with lightning speed, too.

33 S, RS and R models now offering by Audi on a market. All of them have quattro expostulate as standard.

40 millimeters (1.6 in) is how many wider any of a circle arches are on a Audi RS 6 Avant with a conspicuous quattro blisters compared with a A6 Avant. The designers are thereby emphasizing a clever quattro character.

40:60 (front axle:rear axle) is a simple placement of a self-locking core differential in Audi models with longitudinally mounted engines. When necessary, a core differential can obstruct adult to 70 percent of a torque to a front, or adult to 85 percent to a rear.

45.31 percent of all Audi models constructed in 2020 had a quattro all-wheel expostulate system.

The 75th Geneva Motor Show was where Audi presented a strange quattro for a initial time on Mar 3, 1980. Internally, it had a nomination indication 85.

80 percent was a slip of a ski burst in Kaipola, Finland, where Audi filmed a mythological blurb in 1986. Professional convene motorist Harald Demuth mastered a snow-covered 47-meter (154.2-ft) climb in a Audi 100 CS quattro.

92.2 percent of all cars that Audi delivered to business in Canada in 2019 had a quattro drive. As a result, Canada has a top suit of all-wheel expostulate cars in a world.

From 140 kW (190 PS) in a Q2 40 TFSI quattro S tronic right by to 456 kW (620 PS) in a R8 V10 opening quattro supercar, Audi provides a business with a advantages of permanent all-wheel expostulate via a whole indication range.

200 PS (147 kW) is what a strange quattro had during a ordering – 40 years ago, that was a value truly estimable of a sports car. At this point, a Porsche 911 SC constructed usually 4 PS more.

Around 720 PS (530 kW) is what a five-cylinder-turbo in a Audi 90 quattro produced, that competed in a IMSA GTO array in 1989 – a 2.2-liter four-valve powerplant summoned no reduction than 329 PS from each liter (0.04 cu ft) of displacement. The drivers, Hurley Haywood and Hans-Joachim Stuck, won roughly each second competition in a North American series. Audi exploited a technical manners of a IMSA array to a full: A tubular gazebo support upheld a severely widened cosmetic body, while a tires were adult to 360 millimeters (14.2 in) wide.

Up to 973 Nm (717.6 lb-ft) of torque is constructed by a 3 electric motors in a Audi e-tron S and Audi e-tron S Sportback. The dual entirely electric SUV models grasp a energy outlay of 370 kW (507 PS) in boost mode.

The torque splitter, that is carrying a universe premiere in a new Audi RS 3, transfers a limit of adult to 1,750 Nm of torque to one of a back wheels. The new record uses an electronically tranquil multiple-disc purchase on a sold expostulate shaft. This enables active, entirely non-static torque placement between a back wheels. The accurate torque placement depends on a mode that is comparison in Audi expostulate name and on a sold pushing situation.

The winter of 1976/77 is when a thought of building a quattro record came about during Audi. A array of exam drives in Scandinavia, in that a VW Iltis also took part, brought it about. On a snow-covered roads, a troops all-terrain automobile grown during Audi impressively demonstrated a intensity of a all-wheel drive.

1981 was a year Audi strictly entered a rallying stage for a initial time with a quattro. Finishing around 21 mins forward of a competing cars, Franz Wittmann won a Jänner Rallye in Austria, that was partial of a European Rally Championship. The internal favourite triumphed in all 31 special trials. Prior to that, in Nov 1980, a quattro had been used during a Algarve Rallye in Portugal as an unclassified though timed march automobile with extensive success.

1984 was a many successful year for Audi’s quattro drivers in a Rally World Championship. They won a double – both a manufacturer’s and a driver’s titles – with Stig Blomqvist claiming a latter.

In 1988, a Audi 200 competed in a TransAm Series in America. Here too, a Four Rings surfaced a manufacturer’s and driver’s rankings during a initial attempt. The quattro element valid a supremacy on a competition circuit as well.

1994 saw Audi launch a RS 2 Avant on a market, a initial ever RS model. Its quattro expostulate incorporated an electromechanically activated locking differential during a back axle.

In 1999, Audi introduced a quattro expostulate to a reward compress shred for a initial time in a A3 1.8 T with 110 kW (150 PS).

In 2005, Audi presented an RS 4 featuring a initial core differential with asymmetric, energetic simple distribution. It is still being used currently in a some-more polished form. Its asymmetric, energetic torque placement formula in sporty, rear-biased handling.

In 2007 a Audi R8 high-performance sports car launched on a marketplace in a initial generation. Its quattro expostulate was tailor-made: A cardan missile ran from a delivery in a back to an unregulated gelatinous coupling on a front axle. In a stream generation, a R8 uses a tranquil multi-plate purchase here.

2019 saw circuit and rallycross champion Mattias Ekström expostulate adult partial of a snow-covered “Streif” ski racing march during Kitzbühel. In an Audi e-tron quattro with 3 electric motors, he overcame an slip of adult to 85 percent.

2,100 Nm (1548.9 lb-ft) is a estimate torque differential during circle turn that a back wheels can rise in a entirely electric Audi e-tron S and e-tron S Sportback when cornering during speed. Each of a dual back electric motors drives an sold wheel. Usually, a circle on a outward of a bend receives significantly some-more torque than a unloaded inside circle due to a larger traction. This increases pushing dynamics and cornering speed considerably.

11,452 units of a strange quattro were done between 1980 and 1991. Originally, usually 400 were planned.

49,900 German outlines was a bottom cost of a strange Audi quattro during a marketplace launch in 1980. Porsche offering a 911 SC for a same price.

486,000 euros was a cost a fan paid for a an Audi Sport quattro during an auction in London in 2016. Only 214 units of this super-quattro with 306 PS (225 kW) were built. At a launch in 1984, it cost 195,000 German marks.

750,733 is a series of quattro models Audi constructed worldwide in 2020.

The code with a 4 rings has built 11,199,144 cars with quattro drive given 1980 (as of: Dec 31, 2020).
