Audi presents the most powerful car in the premium compact segment: the new Audi RS 3 Sportback produces 270 kW (367 hp) and delivers 465 Nm (343.0 lb-ft) of torque to the crankshaft. The 2.5 TFSI accelerates the five‑door model from 0 to 100 km/h (62.1 mph) in 4.3 seconds and goes on to reach an optional top speed of 280 km/h (174.0 mph).
The five-cylinder unit produces 270 kW (367 hp) from a displacement of 2,480 cc: a remarkable specific output of 108.9 kW (148.0 hp) per liter. The peak torque of 465 Nm (343.0 lb-ft) is already available at 1,625 rpm and remains constant through 5,550 rpm. The sprint from 60 to 100 km/h (37.3 to 62.1 mph) in fourth gear takes just 4.1 seconds; it takes just 5.8 seconds to go from 80 to 120 km/h (49.7 to 74.6 mph) in fifth gear.
The 2.5 TFSI catapults the new Audi RS 3 Sportback to 100 km/h (62.1 mph) from a standing start in 4.3 seconds – the best in its class. Acceleration is electronically capped at 250 km/h (155.3 mph). Top speed can be optionally raised to 280 km/h (174.0 mph), which is also unique in the compact sports car segment. In the NEDC, the entry-level RS model consumes just 8.1 liters of fuel per 100 kilometers (29.0 mph), ten percent less than its predecessor. This corresponds to 189 grams CO2 per kilometer (304.2 g/mi). A recuperation system, a demand-controlled oil pump and a newly developed start-stop system that turns off the engine shortly before the car comes to a stop contribute to this. The emissions rating is Euro 6. The quattro permanent all-wheel drive system transfers the power of the 2.5 TFSI to the road with supreme ease.
The McPherson front suspension has been widened to a track of 1,559 millimeters (5.1 ft) and includes specially developed, high-strength aluminum pivot bearings. The standard progressive steering varies its ratio between 15.3:1 and 10.9:1 as a function of steering input. Its efficient, electromechanical servo boost works with an RS-typical characteristic. The rear axle, which as a track width of 1,514 millimeters (5.0 ft), is a four-link construction with rods of high-strength steel that handle the longitudinal and lateral forces separately. As with the front axle, these forces are directed to a subframe. The taut RS sport suspension lowers the body by 25 millimeters (1.0 in) compared with the A3 Sportback.
The power-to-weight ratio plays a very key role in a sporty car. With the new Audi RS 3 Sportback, each hp has to move just 4.14 kilograms (9.1 lb). The practical five-door compact has a curb weight (without driver) of just 1,520 kilograms (3,351.0 lb), 55 kilograms (121.3 lb) less than its predecessor.
Deliveries of the powerful five-door model are scheduled to begin in summer 2015.
