If there’s one thing the BMW M3 CS doesn’t need, it’s more power. BMW says the twin-turbocharged inline-six under the hood makes 543 horsepower, but from behind the wheel it feels more like 600 horsepower. The one in this video makes 750 horsepower, enough to get the car up to its electronically limited top speed in no time.
The AutoTopNL The YouTube channel managed to get behind the wheel of this M3 CS for a while, customized by H&H Performance, a shop in Northern Germany. There’s no word on specific upgrades, but given the capabilities of BMW’s S58 engine, we wouldn’t be surprised if all that extra power comes from a few simple tweaks and a tune.
The host wastes no time getting up to speed and heads out onto the German Autobahn (where there is no speed limit) to test the upper limits of this CS. What follows are several minutes of repeated acceleration runs, each ending either due to traffic or the car reaching the electronic speed limiter of 304 km/h (189 mph).
We suspect this M3 could go a lot faster if it didn’t have the limiter. From the video it is clear that the car still pulls every time it reaches 300 km/h. It is very likely that this car would reach a speed of 200 miles per hour if it were given the freedom to do so (and it had enough space).
Hopefully next time AutoTopNL If anyone tests this car, the speed limiter will be removed.
