It's fair to say the engineers responsible for the new $78,000, 418-hp Audi RS4 have put their reputations on the line. This is The One, the car that will rocket Audi to the summit of Performance Sedan Mountain, an icon in the making, the long-awaited slayer of legendary BMW M3s and, on top of it all, just about the best car Audi has ever built.
The RS4 sits an inch lower than a standard A4 and the suspension, hood and front fenders are aluminum. The substitution of ultra-light RS buckets keeps weight down to 3850 pounds. The engine develops an M3-withering 418 hp at 7800 rpm and cracks 100 hp per liter. It delivers 90 percent of its 317 lb-ft (at 5500 rpm) of torque peak between 2250 and 7600 rpm. The rev limiter is set at a barely believable 8250 rpm. And if you think the 4.5 seconds Audi claims for the 0-to-60-mph sprint is impressive, 0 to 124 mph in 16.6 seconds turns the M3 into a distant spectator.
