In wasn’t long ago that if you mentioned any other car in the same sentence as the BMW M3, it was the inferior machine. The M3 has been the king of its segment since its inception, with almost no competition. Up until recently, that is. Competition of the M3’s throne has grown stronger than ever. The Cadillac ATS-V and Mercedes-AMG C63 S are the two rivals with a shot of dethroning the mighty M3, and the matchup is closer than one might think.

Well, Motor Trend had the good fortune to pit these three super sedans against each other and see which is best.

The C63 isn’t a newcomer to the battle, as it tried to take down the king in its last generation, with little success. The previous C63 was good and very fun, but it didn’t’ have the precision and driveability that the M3 had. This new model, however, is a proper driving machine. According to Motor Trend, while the ATS-V couldn’t pass the M3 on twisty mountain roads, neither the ATS-V nor the M3 could keep up with the big Benz. With 505 hp, it’s also the most powerful by far, though it is also the heaviest of the bunch by far, weighing in at 3,936 lbs. Its 4.0 second 0-60 mph time is also tied with the M3 for second place. But the extra power on the real roads gives the Benz the advantage. As well as a more confidence-inspiring chassis.

The BMW M3 is still the most trackable car of the bunch. It’s the most like a race car. You have to work at it to get the most out of it. So while the M3 is equally as fast as the C63, it’s a little more nervous feeling on tight roads, which causes it to fall behind the rock solid Benz. However, the M3 is still the driver’s car of the bunch. It’s fluid and fast, with an absolute rockstar of an engine. The twin-turbo I6 just pulls and pulls, also revving out further than the other two, with a 7,500 rpm redline compared to the Benz’s 7,000 and the Caddy’s quite low 6,500. The only real issue with the M3, according to Motor Trend, was the overactive traction control system, which kept intervening. Obviously, it can be turned off, but they felt that wasn’t too safe an idea on twisty mountain roads.

The Cadillac ATS-V is the real surprise of the bunch. It’s far faster than both, pulling a 0-60 mph time of 3.7 seconds, is faster around the track and stops from 60-0 is less distance than the other two. It’s the performer of the bunch, which is surprising from a brand whose main clientele put their teeth in jars at night. But make no mistake, this ain’t your Grand Dad’s Cadillac. Where the ATS-V falls down is in its powertrain. While it’s sensationally fast, it doesn’t rev high enough to allow for any fun nor does it sound good doing it. So all of that fury seems rather tame in comparison with the Bimmer’s snarl and the Benz’s roar.

In the end, Motor Trend declared the Mercedes-AMG C63 S the victor. It was equally as fast as the Bimmer and almost as fast as the Caddy, handled better than both apparently and has the more exciting V8 engine.The Cadillac ATS-V came in second place, being the best performer on paper than the other and actually being fun to drive, but falling down because of its powertrain. The might BMW M3 came in dead last for, well, unexplained reasons. The Bimmer seemed to tick a lot of boxes and sounded more fun to drive than the ATS-V, but came in last. We can’t really tell which is best without testing them for ourselves, but according to Motor Trend, the king has been defeated.

    M3 a full second slower than the C63S On a “small” track (Well this is a 1min 30 car, looks kinda small)… Also braking distance not so good, and not as quick as the C in the straight…
    Ok guys which one of you were hiding in the trunk ?!

  2. Giom says:

    Motor trend have always been dead set against BMW, no surprise here. But they MUST feel a little stupid being the ONLY mag not putting the M3 first.

    Never driven a C63 AMG, but I can’t imagine a car that’s almost 4,000 lb is as fun to drive as my M3. I’m not even sure they are in the same category.

      Previous M3 coupe driver. Had to decide between these 2 cars three months ago. Currently own a C63S. No regrets.

      • dsa127 says:

        I’m sure it’s a beast. But I’d be more likely to compare it to a Corvette, M5, or some other big V8 bruiser than an M3 (Though the M3 HAS gotten a little bloated in recent years).

    I’ve said this before – It’s a great time to be around if you like sports sedans.
    All three of these cars are great and would be enjoyable to drive on a daily basis. You can pull music without commercials from space, you can talk on the phone with both hands on the wheel, you can heat and cool your seat and the damn things are faster than muscle cars and Ferrari’s from not too long ago – but with a ride that won’t rattle the fillings out of your head.
    Not bad.

  5. Mike says:

    everyone knows that MotorTrend have been biased and always against BMW, i understand if the pick the c63s but when they said the Cadillac is better than M3.. Lol thats definitely a joke. Watch evo track battle video in YouTube where M3 wins, to me that looked fair. This is just rubbish.
