Audi RS 4
The Audi RS4 quattro is the top tier and highest performing version of some specific generations of the Audi A4 range of automobiles.
The original version was only produced as a five-door five-seat "Avant", Audi's name for an estate car/station wagon.
The original B5 Audi RS4 Avant quattro was introduced in late 1999, for main production and sale from 2000.
For the powertrain detail of the RS4, its motive power came from a modified version of the S4's 2.7 liter V6 'biturbo'—a 2,671 cubic centimeters (163.0 cu in), 30 valve (five valves per cylinder) 90° V6 engine. The modifications were enough to increase the engine's power output from the 261 bhp and 400 newton meters (295 ft·lbf) of torque on the S4; to 375 bhp at 7,000 revolutions per minute (rpm) and 440 newton meters (325 ft·lbf) at 6,000 rpm.
Even with a curb weight of 3,571 lb, the RS4's powerful engine gave it the performance of a sports car. The 0 to 100 kilometers per hour (0 to 62.1 mph) dash could be reached in just 4.9 seconds, and a top speed was electronically governed to 250 kilometers per hour (155.3 mph).
