Rumors have claimed the new M8 CSL will have 700 horsepower.
Over the last few months, BMW has been testing updated versions of the 8 Series Coupe, Convertible, and Gran Coupe, as the Bavarian automaker prepares to give the entire 8 Series range a facelift to try and boost sales. Don't expect any dramatic changes: the styling will get some minor tweaks and the interior will be upgraded with a larger infotainment system. However, it looks like BMW has bigger plans for the M8.
Last year, a mysterious 8 Series prototype was spotted in the wild with side air intakes replacing the rear windows and different side sills. This led to speculation that BMW was testing a mule for a new mid-engine sports car. BMW denied these rumors, claiming that the test mule was being used to test new performance parts.
Now, our spies have spotted a mysterious M8 prototype lapping the Nurburgring, and this time it's practically undisguised. Potentially, we could be looking at a prototype for a new hot M8 CSL. The prototype has some noticeable styling changes compared to the M8 Competition, including a new grille with red accents and a 3D design. Red accents are also applied to the air outlets on the front fenders. There's also a redesigned bumper and a more aggressive, front splitter.
BMW has camouflaged the rear, but it can't hide the massive carbon fiber rear wing generating more downforce to help keep the car glued to the track.
The rear diffuser has also been modified to fit a central rear light and the rear taillights look darker. To reduce the weight, the M8 CSL is expected to feature lighter glass. Anything unnecessary like the rear seat will also be removed to make the M8 CSL as light as possible.
Under the hood, the M8 CSL will reportedly use the same electrified setup as the upcoming X8 M combining a 3.0-liter six-cylinder and electric motors. Combined, this setup could generate around 700 horsepower. This would be a significant improvement over the current M8 Competition, which produces 617 hp and 553 lb-ft of torque from a 4.4-liter twin-turbo V8. Rumors suggest the M8 CSL will go on sale in 2022.
