The BMW M8 Competition Gran Coupe is one seriously impressive sedan and as this video shows, is more than happy to cruise along the Autobahn at high speeds.

As standard, the 4.4-liter twin-turbocharged V8 of the M8 Competition Gran Coupe churns out 617 hp and 553 lb-ft (750 Nm) of torque. The car featured is far from stock, though. In fact, it has been modified by the tuning specialists over at G-Power and according to AutoTopNL, pumps out 790 hp.

We presume this M8 Competition Gran Coupe has gone through the Stage 3 modifications that G-Power announced earlier this year. If that’s the case then it would feature new performance software, upgraded turbochargers, sport downpipes, a GP-Deeptone exhaust system, and four carbon fiber tailpipes.

G-Power says its boosted BMW delivers 808 hp and 738 lb-ft (1,000 Nm) of torque, an extraordinary amount of power for a luxury sedan that offers levels of comfort, ride quality, and refinement to make it perfect for cross-continent journeys. While the video quotes a slightly lower number, 790 hp is still more than enough for any occasion.

This video doesn’t provide us with any performance times recorded by the car but does show it exceeding 180 mph (290 km/h) without breaking a sweat. We suspect that with enough open road in front of it, the car could probably hit 200 mph (320 km/h), if not slightly exceed it.
