One of the most popular car comparisons these days is the one between the BMW M3 Coupe and Audi’s latest RS5. According to Autocar, the Audi RS5 is slightly quicker than the M3 and Audi’s best car after the R8.
Here are the technical specs of the two sporty coupes.
The M3 is powered by the S65B40 engine, a naturally aspirated, high revving 4-liter V8 (based on the S85B50 5-liter V10 that powers the E60/E61 M5 and the E63/E64 M6 to date) delivering 414 horsepower (309 kW; 420 PS) at 8,300 rpm and peak torque of 400 Nm (300 lb-ft) at 3,900 rpm.
Based on the A5 coupe, RS5’s 4.2-liter V-8 makes 450 hp at 8250 rpm – coincidentally, about 30 horsepower over the 4.0L V8 of the M3 – and maximum torque is 317 lb-ft, available between 4000 and 6000 rpm. The hand-built engine is direct-injected and closely related to the 420-hp V-8 which powers the R8 supercar.
Top speed is electronically governed at 155 mph or 174 mph, spec’d to your order. Zero to 62 mph is accomplished in a claimed 4.6 seconds.
