This Is a Mid-Engined BMW M4 Race Car and It's Kind of Perfect
It has a 500-horsepower E46 M3 CSL engine mounted behind the driver.
At first glance, this M4 racecar looks like nothing out of the ordinary. It has the same dimensions as the BMW M car we all know and love, with some typical aero racing bits tacked on. Except, it's not an M4 at all. It's actually a mid-engine time attack monster.
This car, dubbed the "M4 Silhouette," started out life as a standard BMW M4 coupe. RaceTech, a shop in Lithuania, thought it would be a good idea to simply take away the 3.0-liter, twin-turbo straight-six engine at the front of the car, and replace it with a mid-mounted naturally aspirated six-cylinder motor from the E46 M3 CSL. Besides the obvious engineering and fabricating obstacles, making everything work together and still keeping the original car's shape must've been no small feat.
And it doesn't end there. The video's description says the car weighs just around 2200 pounds thanks to heavy carbon fiber usage, and puts out around 500 horsepower from that naturally aspirated CSL engine. Not only does it perform, but it sounds great doing it.
Watch and listen as it rips some laps around the TT Circuit Assen in the Netherlands.
