In a recent video, Cars.co.za put the Audi RS3 up against the BMW M2 Coupe. The RS3 was faster in a straight line while the BMW M2 was faster around the circuit. Those cars, while similar on paper, are so different in practice. The RS3 is an all-wheel drive beast of a car that’s designed to be fast and capable every day in any kind of weather. The BMW M2 is designed to be an agile, delicate sports car. So the Mercedes-AMG A45 is actually more similar to the Audi RS3, as both are practical, all-wheel drive performance machines. So which is faster in a straight-line drag race?
Racing on a shorter drag strip, Cars.co.za finds out which car is faster in a sort of stop-light-to-stop-light drag race. Which is actually sort of useful, as that’s really where people are going to test the straight-line performance of their cars in the real world.
On paper, the Audi RS3 Sedan has the edge. Its 2.5 liter turbocharged I5 engine makes 400 hp and 354 lb-ft of torque. When paired with a seven-speed dual-clutch auto and Quattro all-wheel drive, the RS3 Sedan is capable of 0-60 mph in under four seconds. While the Mercedes-AMG A45 makes 376 hp and 350 lb-ft of torque from its 2.0 liter turbo-four. That, too, is mated to a seven-speed dual-clutch ‘box and has all-wheel drive, which gets it to 60 mph in 4.2 seconds. So while the AMG is quick, it’s not as quick as the RS3.
Once the race starts, the Audi RS3 flies off the line, quickly gaining a lead over the Mercedes-AMG. While the AMG is the lighter car of the two, it never even sniffs the RS3’s taillights. The Audi’s lead just continues to build as they near the finish line. So the Audi RS3 dominates the AMG A45, even though it doesn’t have that much more power and torque. Chalk that up to its all-wheel drive system’s better grip and punchier engine that delivers power lower in the rev range.
