Here we have an epic duel between a Bugatti Chiron and a BRABUS-sourced Mercedes-Benz CLS63 S AMG.
You don’t see a Bugatti every day, and certainly not their latest model, the Chiron. With over 1,400 horsepower on tap, nobody in their right mind would think they have a chance against this monster in a race. But the kind of people that purchase a tuned Mercedes-AMG sedan are the kind of people that want to know how their creation stacks up against the best.
Even though this CLS 63 S is tuned by one of the premiere tuning houses in Germany, it still has an enormous mountain to climb in order to reach Bugatti Chiron heights.
What we know about the car mostly comes from the video description. This is a BRABUS model CLS63, so instead of the usual 5.5-L twin-turbo V8 this one has an even larger 6.0-L twin-turbo V8. Power is rated at 912 horses, which is a far cry from the Chiron’s 1,479, but maybe the CLS63 will gain on the weight advantage.
Probably not though. The CSL63 weighs around 4,200 lbs without the larger engine, so unless LA Performance managed to knock off quite a few lbs it’s practically the same weight as the Chiron.
Meanwhile, the Chiron is a beast of a car. An 8.0-L twin-turbo W16 powers this thing to an electronically limited top speed of 261 mph. It could go faster, but Bugatti has never taken the limiters off to find out.
As we mentioned 1,479 horsepower is the number to beat, along with 1,180 lb-ft of torque. Zero to sixty is done in 2.3 seconds and it also has AWD for more consistent acceleration off the line.
However, since this race is in Germany, this won’t be a standard drag race. Instead, we have a rolling race that begins at 50 kph (or 31 mph) where AWD won’t have as much of an advantage.
But having an extra 500 horsepower is more than enough advantage for the Chiron. The Mercedes gives a good account for itself, but it’s not going to catch a Chiron in almost any scenario.
