[Video] BMW M550i Reaches Threshold Speed in 6th Gear

While the rest of the world is still waiting for deliveries of the new BMW M5, some lucky journalists were already able to drive the BMW M550i. In this footage from AutoTopNL, they are having lots of fun with the F90 M5 and what it is capable of. As you’re about to see, the M550i also reaches its limiter with plenty of power left in the tank, the 250 km/h (155 mph) threshold being reached in 6th gear. Since the car comes with an 8-speed ZF automatic gearbox, we can only assume that going up to maybe 300 km/h (186 mph) might just be doable there was no electronic limiter.

The BMW M550i comes with xDrive and that helps when it comes to putting down the power at launch. The 4.4-liter twin-turbo V8 under the hood was tuned to make slightly more power than the outgoing unit that used to be fitted on the F10 550i. In this application the N63 mill makes 462 PS and 650 Nm (479 lb-ft) of toque which definitely seem enough to turn it into an Autobahn beast.
