It was 1980. At the Geneva Motor Show made its debut at the Audi Quattro, a fundamental model in history for all-wheel drive applications that have followed on the production and subsequent to the successes scored in rally racing in the Sport version Four more prestigious in the world (the Monte Carlo Rally, Pikes Peak …). The ‘Audi Quattro Concept pays tribute to the first successful car and its even sportier version with shortened step and power output of 306 hp. It’s called Quattro Concept and is a bold exercise in style and mechanics , high-performance designed by extensive use of technology.
Painted white color in the exciting Col de Turini, starts from Audi RS5 but has a more bold, more aggressive, which immediately declared its full potential. Compared to this is also lower (40 mm), thus enhancing the impression of the center of gravity shifted downward. The wheelbase is also shorter than 150 mm to increase agility and save important kilos. Dimensionally, therefore, the dimensions are not that far away from his predecessor. The Quattro Concept is 428 cm long, 186 wide, 133 high and has a wheelbase of 260 cm. Reminiscences of the “old” Four can also be found in the widened wheel arches and air vents on the bonnet. In front stands the grid without chrome frame, a touch of simplicity and rationality at a car that should be only super-fast. The body is lightweight aluminum alloy assembled according to the principles of Audi Space Frame ASF technology. However, hoods, spoiler and bumpers are made of carbon fiber. Overall, the outdoor clothing weighs 159 pounds, 50% less than using steel as on audio RS5 from which it derives. The entire car declaring a total weight of 1,300 pounds, 200 less than the Audi TT-RS which also makes extensive use of aluminum.
The interior of the Quattro Concept is a rare example of rationality and simplicity of design. The rear seats have been eliminated as a result of the reduction step. In their place, a little hole for luggage. The front seats, and nuts, are equipped with competition harnesses and weigh 18 pounds each. The bridge, in carbon fiber, is a harmony of structural material exposed naked and covered in leather. Before the pilot, three-spoke steering wheel with an antique flavor and full digital instrumentation inspired by the Audi Quattro of the ’80s (in particular the “strip” of the revolution in lighting and the large digital display Progressive speed). High on the central tunnel, well covered with skin side is the six-speed gear lever in a raised position, the button for the ignition and controls the multimedia system Audi MMI that integrates audio and navigation system.
From the same TT-RS Quattro Concept takes the engine to 2,480 cc 5-cylinder with variable geometry turbo technology (IST) in place of the generous air dell’RS5 V8. However, on this fascinating prototype, the engine is positioned longitudinally (transversely in the engine compartment of the TT). The maximum power is also of 408 hp between 5,400 and 6,500 rpm (vs. 340, engine starting). Maximum torque is an impressive 480 Nm at 1,600 rpm already available and served up to 5,300 rpm. The drive is led by an innovative system of four-wheel drive system with three differentials. In the central one, in particular, houses two new gears rotating crown, the first agent that transmits the drive shaft to the front differential, the second towards the rear axle. Of course, the system is totally variable. Under normal conditions, the traction is guaranteed to 50% on both axes, but in need you can send up to 85% of torque to the front wheels or 70% to the rear. In addition, the Quattro Sport is equipped with limited slip differential sport acting on the rear wheels to help traction in corners and avoiding any signs of drift. The transmission is connected to a six-speed transmission through a multi-disc clutch provided with electro-hydraulic actuator. The behavior typically sporty chassis Quattro Concept is enhanced by suspensions designed for this purpose. Before there is a five-aluminum arms, trapezoidal rear suspension are attached to a subframe. The fund consists of brake discs in carbon ceramic large calipers with six pistons. The footprint on the ground, finally, is ensured by wheels 20 ” (with one clamping nut) with tires 275/30. Performance? Audi says that the Quattro Concept accelerates from 0 to 100 in just 3 “9 / 2, but, in spite of so much power, thanks to low weight, can be quite “normal” consumption: 8.5 litres/100 km under the manufacturer.
