Motore 5 cilindri in linea FSI Turbo da 2.5 litri e 408Cv. Lo 0-100 viene coperto in 3.9s

In another move that benefits the vehicle's weight, the eight-cylinder engine from the production model has been replaced under the hood by a turbocharged, inline five-cylinder engine that can trace its roots back to another Audi sports car - the TT RS. In the Audi quattro Concept, the longitudinal FSI turbo produces 300 kW (408 hp) and accelerates the car from 0 to 100 km/h (62.14 mph) in only 3.9 seconds. Torque is distributed as needed via a six-speed manual transmission.

The Audi quattro Concept uses the latest evolutionary stage of the quattro permanent all-wheel drive system to deliver its power to the road. The key innovation, the crown-gear center differential, is compact, lightweight, and can vary the distribution of power between the front and rear axles over a broad range, enabling the quattro drive system to react within milliseconds to coax the maximum of fun and safety out of every last bit of torque.

Le dimensioni:

  • 4.28 m lunghezza
  • 1.86 m larghezza
  • 1.33 m altezza
  • con un passo di 2.60 m

InteriorThe interior of the coupé is reduced and clean. The dashboard is very slender and seems to float over the separate center console. Shortening the wheelbase meant losing the rear seat of the RS5 on which it is based. In its place is a shelf for helmets or luggage. Awaiting the two occupants are filigree bucket seats, during whose development the issue of lightweight design played a central role. They weigh only 18 kilograms (39.68 lb) each - a weight advantage of roughly 40 percent versus a conventional production seat. The seats are equipped with either three- or four-point belts.

Body

A true sports car is always a light car, and the Audi quattro Concept shines in this discipline as well.

The key factors are the choice of material and the design. Rather than mostly steel as in the Audi RS5, the body comprises lightweight aluminum components assembled using Audi Space Frame ASF technology. Extruded sections, die-castings and aluminum sheets form an impact-resistant structure of exceptional strength. The hood and the rear hatch with its integrated, moveable spoiler, plus the bumpers and numerous aerodynamic components are made of even lighter and high-strength carbon.

The body-in-white of the coupé weighs just 159 kilograms (350.53 lb); it would be nearly 50 percent heavier if made entirely of steel.

The low weight of the superstructure leads to significant secondary effects regarding size and weight in other components of the vehicle, such as the transmission, the chassis and the brake system. All together the Audi quattro Concept tips the scales at just 1,300 kilograms (2,866.01 lb), which is roughly 200 kilograms (440.92 lb) lighter than even the comparably sized Audi TT RS, whose body is also largely made of aluminum.

Turbocharged gasoline engines are a traditional Audi domain, and the five-cylinder turbo in the Audi quattro Concept is also a high-performance engine. Displacing 2,480 cubic centimeters, it produces 300 kW (408 hp) between 5,400 and 6,500 rpm. Peak torque of 480 Nm (354.03 lb ft) is already available at 1,600 and remains constant through 5,300 rpm. The powerful unit accelerates the Audi quattro Concept from 0 to 100 km/h (62.14 mph) in just 3.9 seconds.

Inside the new center differential are two rotating crown gears that owe their name to the crown-like design of their teeth. The front crown gear drives the output shaft to the front differential, the rear crown gear the propshaft to the rear axle. The connection here is provided by an ambitious construction. The new drivetrain design is roughly 3 kilograms (6.61 lb) lighter than the previous one.

The crown gears mesh with four rotatable pinion gears. They are arranged at right angles to each other and are driven by the differential's housing, i.e. by the transmission output shaft.

Under normal driving conditions, the two crown gears rotate at the same speed as the housing. Because of their special geometry, they have specifically unequal lever effects. Normally 60 percent of the engine torque goes to the rear differential and 40 percent to the front differential.

If the torques change because one axle loses grip, different speeds and axial forces occur inside the differential and the integrated plate packages are pressed together. The resulting self-locking effect now diverts the majority of the torque to the axle with the better traction; up to 85 percent can flow to the back. In the opposite scenario - if the rear axle has less traction - the same happens in reverse; now up to 70 percent of the torque is diverted to the front axle.

With this extremely broad torque distribution range, the crown-gear center differential surpasses its predecessors - grip becomes even better. Forces are redistributed without any time lag and absolutely consistently. The mechanical operating principle guarantees maximum efficiency and immediate response. Other strong points of the crown-gear differential are its compactness and low weight - at 4.8 kilograms (10.58 lb) it is roughly two kilograms (4.41 lb) lighter than the previous unit.

Bella bella bella. Un attimo spiazzante al primo impatto, ma, appena l'occhio fa l'abitudine al ritorno delle linee ottantesche, ci si rende conto che è un lavoro di design ineccepibile.

Mi piacerebbe vederla in strada, un giorno (magari senza il mega-spoiler)...

La teoria è quando si conosce il funzionamento di qualcosa ma quel qualcosa non funziona.

La pratica è quando tutto funziona ma non si sa come.

Spesso si finisce con il coniugare la teoria con la pratica: non funziona niente e non si sa il perché.

molto interessante, la quattro e' una delle poche audi ad averme gustato, questa, magari con una bocca un po' meno esagerata, sarebbe una degna erede. Se arrivasse su strada sarebbe un'ottima tentazione per che cercasse una berlinetta sportiva a trazione intergrale con un po' di bagagliaio e un po' di posto per ii passeggeri
