Tuned Audi RS3 vs Porsche 911 Turbo S vs tuned BMW M5 drag race

The Porsche 911 Turbo S is the fastest stock car we’ve ever raced here at carwow, but now it faces its toughest challenge yet as Mat pits it against a tuned Audi RS3 and a heavily upgraded BMW M5

The Porsche packs a familiar 3.8-litre twin-turbo flat-six engine with 650hp and 800Nm of torque – usually enough to edge it ahead of whatever exotic machinery you’d care to line up next to it.

Its grippy four-wheel-drive system and quick-fire eight-speed dual-clutch automatic gearbox make it one of the fastest-accelerating cars on sale, too. It does cost a whopping £156,000, however.

But while the RS3 we have here today doesn’t look all that rapid, it’s actually one of the most powerful cars we’ve ever tested. Its 2.5-litre turbocharged five-cylinder engine produces 800hp and 950Nm of torque.

Like the Porsche, this Audi gets four-wheel drive and a dual-clutch automatic gearbox, just with seven speeds to the 911’s eight. All-in, this car and its modifications will set you back around £75,000.

Finally, we come to the M5. This particular example has had 1,000hp and 1,100Nm of torque extracted from its 4.4-litre twin-turbo V8 engine. It too has four-wheel drive, although in this state of tune, its eight-speed automatic gearbox can’t use the standard car’s launch control. In terms of price, this particular M5 will set you back around £130,000.

When it comes to drag racing, weight is just as important as power. And, the lightest car here is the 1,500kg Audi RS3. The Porsche is next with its 1,650kg kerb weight, while the heavyweight BMW tips the scales at 1,970kg. Think you know which car is going to win? Watch the video to find out.
