The BMW M4 and Mercedes-AMG C63 S Coupe have been doing battle ever since the latter came out. These two cars have very different skill sets. One is a track-oriented, precision performance car. The other is a tire-smoking hooligan with a lovely interior. So there’s a specific customer for each car. But what about their newest competitor, the Audi RS5 Coupe? That car sort of splits the difference between the two, in terms of target and scope. But which one is fastest? Carwow finds out in this newest video.

So they lined all three cars up for a standing drag race. The Audi RS5 was being driven by Carwow’s Mat Watson and the BMW M4 was driven by Paul Wallace, of Supercars of London. The BMW M4 has a 3.0 liter turbocharged I6 engine that makes 425 hp and 406 lb-ft of torque. That power is sent through a seven-speed DCT to the rear wheels. As for the Mercedes-AMG C63 S Coupe, it has a 4.0 liter twin-turbocharged V8 making 503 hp and 516 lb-ft of torque which sends power through a seven-speed DCT to the rear wheels as well. The Audi RS5 is the most different car of the trio. It has a 2.9 liter twin-turbocharged V6 that makes 450 hp and 443 lb-ft of torque, all of which is sent through an eight-speed ZF-auto to all four wheels.

So which of the three is fastest in a quarter-mile drag race? Off the line, the Audi RS5 uses its Quattro all-wheel drive grip to fire off the line ahead of the other two. The M3 and AMG stay pretty neck-and-neck for the beginning of the race, while the RS5 simply leaves them for dead. Halfway through the race, the AMG pulls ahead of the Bimmer and starts catching the RS5. Though, it can’t catch up quick enough, as the race ends with the RS5 winning, the AMG in second and the BMW M4 in third.

Next up is a rolling drag race, to see which is quickest to accelerate while already on the move. So all three cars start rolling at 50 mph and are lined up next to each other at speed. On the count of three, they all put their foot down and the result isn’t all that shocking. The AMG, with by far the most power, simply obliterates the other two. What’s surprising is that the RS5, which dominated off the line, loses this race to the Bimmer as well.

So the RS5’s Quattro grip allows it to be fastest to launch off the line. But it’s the AMG’s monster power that makes it faster in the real world. The BMW M4 is the slowest off the line, thanks to the least amount of torque here and its overly aggressive rear diff.

    If you’d go by numbers alone, the M4 should be twaddling there in the background somewhere, wondering how to compete with the numbers deficit. In stead, it manage to not only keep up, but show the RS5 a thing or two from a rolling start. In my books, this M4 is simply shining. This video, if nothing else, shows how brilliant the M car still is.

    It’s all fun and games until a corner comes… Then the M4 just blasts out of sight.

    I just don’t understand why no comparo video (usually overseas publications such as this video) can ever get an F8X to perform cleanly during a drag race. It’s always a sub 4 second run to 0-60 or a mid 12’s quarter run 🤔. I understand that’s not what the F8X is about but it’s a shame that nobody can drive these cars properly during these instrument tests.

      The F80 is a very hard car to launch cleanly. The way the engine delivers power makes it hard to manage traction. My M2 has less power and torque on the same wheels and tires as the M3/4 and it will happily spin its wheels into 3rd gear when launched. Imagine how much harder it is with more power ant torque and a twitchy power delivery.

    I wonder why the M4 didn’t have the competition wheels, if it really has the competition package…

      Lots of CP owners choose not to option the 666m wheels. It’s a bit of a polarising design. Personally in black and 18-19 inch they’d be great, but shiny 20s? No thanks.
