It’s a naturally aspirated V-8 vs a forced induction straight-sixby Sidd Dhimaan, on LISTEN 03:21
The Mercedes-AMG SLS is an iconic machine and it will go down in the history books as one of the most legendary monikers to have ever graced us. It isn’t just about that long hood or the gullwing doors; the car is a beast on the track. The folks at Carwow pit it against a BMW M3 Competition to set up a naturally aspirated V-8 vs a twin-turbo straight-six. Do you think the SLS has in it to take down the turbocharged M3?
The M3 Isn’t As Powerful And Is Heavier
The Mercedes-AMG SLS Black Series is powered by a 6.2-liter, naturally aspirated V-8 engine that puts out 631 horses and 468 pound-feet of torque.
A seven-speed dual-clutch automatic gearbox drives the rear wheels. The timeless beauty weighs 3,417 pounds.
The BMW M3 Competition comes with a 3.0-liter, twin-turbocharged six-cylinder mill that makes 510 ponies and 479 pound-feet of twist.
An eight-speed automatic gearbox powers the rear wheels exclusively. It stands in at, 3,814 pounds; close to 400 pounds more than the SLS.
This Is An Interesting Match-Up
They kicked off the races with a drag race. The BMW suffered a wheel spin which allowed the AMG SLS to take advantage and get a decent lead. The M3 couldn’t catch up and its German counterpart went on to win the race.
The second race witnessed the M3 get a near-perfect launch and that proved to be the difference. The SLS doesn’t have the best launch control system and it led to the car’s downfall in the second race to level 1-1 in this best-of-three race.
For the final race, Mat deactivated the launch control. This worked wonders as it was able to neutralize the BMW’s yet another great launch. The Bimmer was a tad bit ahead in the first half of the race, but the free-revving AMG beast soon caught and went on to win this race by the nose. Well, you can’t fault the BMW here, considering what a long nose the SLS has. Can we call it Pinocchio?
Then we had the rolling race from 50 mph with the car locked in the comfort setting. The BMW had a great kickdown and it flew past its rival. But, the SLS started to catch it and beat the BMW at the half-mile mark. They gave it a shot again, but this time with the cars in sports mode and manual mode. The forced induction of the M3 was no match for the naturally aspirated V-8 of the SLS as the latter stayed ahead right from the kickdown to the finish line.
The cars then proceeded for a brake test from 100 mph. The BMW stopped in a much shorter distance, taking Watson by surprise. It could be that the car was riding on the old brakes, but the distance sure seemed a little too much even though the SLS is nearly 400 pounds lighter.
