AutoExpress UK compares the new 2013 BMW M6 Convertible against a similar offering from Mercedes-Benz, the SL63 AMG. The M6 is powered by the S53Tu 4.4 liter V8 TwinPower turbocharged engine employing the M division’s patented manifold that evenly spaces out exhaust pulses. With a peak turbo boost of 21.7 psi, the M-built engine produces 560 hp and 500 lb-ft of torque that now is delivered in a flat band between 1500 and 5750 rpm.

The performance is also possible thanks to twice as large intercoolers compared to the ones found in the X5M/X6M models and of course, the unique Valvetronic. Compared to the highly-acclaimed, now retired, 5.0 liter V10, the new unit found in the M5 and M6 not only has 10 percent more ponies, but it also improves its efficiency by nearly 30 percent, in part thanks to the engine stop-start feature.

See our test drive of the 2012 BMW M6 Convertible

Based on the SL-Class that debuted at the 2012 Detroit Auto Show, the SL63 AMG packs a twin-turbo 5.5 liter V8 producing 529 horsepower (557 with AMG Performance Package) and 664 lb-ft of torque. The new SL63 AMG can rocket from 0-62 mph in 4.3 seconds (4.2 with the optional AMG Performance Package) while returning 30 percent better fuel economy. Top speed rises to 186 mph.

The SL63 AMG is being picked by AutoExpress as the winner of this comparison, but there are a few things worth pointing. The M6 is a Gran Turismo car with space for four, therefore weighing more, while the SL63 is a high-end roadster seating two people. One other important factor is the lack of ceramic brakes on the M6, an important detail that on track has the highest impact on the performance of a car.

    That is pretty bad when even AMG beats a M-car on the track. Just goes to show how heavy BMWs are today. Sure the whole car industry has made their cars heavier, but BMW is sort of the leader in that department now…Not that I’d buy a Merc now, but BMW doesn’t seem to care for us who want a lightweight sportcar that is not just about massive amounts of power. All we want is something that they have done so well for so long yet now abandoned it. Sub 1400 kg coupe or sedan with 6 speed manual, LSD and around 200hp. Sounds awfully lot like Toyota GT86, I’m still patiently waiting for BMW’s answer to that car though…

      They are not even, the M6 is a 4 seater comfortable GT, while the SL63 is a hardcore roadster. If Benz had an E63 AMG Convertible, maybe that would be even.

      Do your homework 2 different cars . sorry youre comparing Apples and Lemons ! again these Journalists. Im tired of them and their comparisons just to make a report for their Magazine.

      • Auto Fan says:

        Of course, MB shouldn’t be compared to worse-than-VW Golf BMW. At last you said something reasonable, idiot.

  2. AMGshit says:

    This test is bullshit , a BMW M6 convertible 0-60 in 5.3? 3.9 seconds is the best result , and no PP package could outrun a beemer in peformance figures.FAKE!

    The track side shots they showed of the M6, every corner was wide. It could be due to the M6s weight, I’m just saying, the racing lines in the Merc was better. Could have been on purpose, could have been unrelated footage, it’s my observation.
    I am surprised that the AMG is lighter than the BMW. Even with its metal folding roof!? What on earth accounts for all the weight in the M6?

    • Auto Fan says:

      BMW is beaten by Mercedes-Benz and Audi with any respect. You have to accept it and switch to either MB or Audi.

    Mercedes-Benz hopelessly kicks BMW’s pathetic ass. Another of too many testimonies that MB is the best in its segment, and BMW is just for fools and hopeless losers who like buying a car that isn’t the best at anything.
    And a very funny notion in the above-mentioned text: ” the lack of ceramic brakes on the M6″. Well, if BMW’s engineers notion of sports car is “a car without brakes”, then t’s not surprising why the whole world laughs at stupid BMW.
    So burn in envy, pathetic BMW loser fans!!!!!
    Mercedes-Benz is the best, and Audi is the 2nd. And BMW is the only useless car company in the world.So eat shit, BMW fans!!!!!

    The only close competitor to that M6 is the Maserati GranTurismo.
    Now, what would make a decent person to choose a M6 over a GranTurismo? Only answer is brain damage I guess.

    Have to smile at this comp. I own a 2014 M6, 2007 M5, and the 2012 CL63 AMG. First of all the benz has been in the shop 4 times in the past year and my BMW’s once-for an alignment. MB is a great car no doubt BUT not when it come to pure driving experience. BMW and MB are both winners on the track but the MB is a headache to maintain
