BMW announced last year that the BMW M8 Coupe and Convertible would be skipping the 2021 year model, meaning that if you want a 2021 M8-badged BMW, it will have to be the M8 Gran Coupe. Previously AC Schnitzer revealed a 720-horsepower version of the M8 Gran Coupe, but G-Power has just trumped that with an 809-hp monster. Then again, the Gran Coupe is perhaps the prettiest of all 8 Series models, so that is no hardship. It is one the quickest BMW stock that you can buy, but as expected, the aftermarket has a lot to say about it.

 

 

It is more potent than BMW M Division’s most powerful cat production ever, the recently unveiled M5 CS sedan; this extreme M5 manages 627 hp. Together with the modified M8's 809 horses is no less than 738 lb-ft of torque. These are the numbers available with the most powerful Stage 3 GP-820 performance software, although, without an unlimited tire budget, two lower-powered packages are also on offer for customers. G-Power will remove the Vmax limiter to increase the top speed to 205 mph. The GP-deep tone exhaust system with carbon tailpipes is also included in the GP-820 package.

 

 

No 0-60 mph time was indicated but considering that the stock M8 Competition can accomplish the sprint in just three seconds, G-Power's M8 should be safely into supercar territory. G Power claims that cold and hot-testing of the upgrade has been completed in various climate zones.
