BMW is working on a new engine for its diesel cars, and it’ll be packing three turbos for the X6 and the 7-Series—just like the next M3. The Tri-Turbo will be a 3.0-liter six-cylinder engine with more turbochargers than BMW’s twin-turbo models, but less than Bugatti’s quad-turbo engine. Combined, power of these pinwheels will be between 350 and 400 horsepower.
The engine is currently being tested in the 750d and 750ld flagships, which will be introduced at the Frankfurt Auto Show in September, and Europeans will be able to three-ball it starting next spring.
