BMW Prepping Quad-Turbo Diesel with Over 400 HP

BMW is planning a new M750d model powered by a quad-turbocharged diesel engine.

It is being reported that the new powerplant will replace the German automaker’s existing tri-turbo diesel engine, with the new oil burner being a 3.0-liter inline six with over 400 hp and 590 lb-ft of torque.

Although details are light, it is believed that the quad-turbo engine builds on the current tri-turbo engine found in the M550d and X5 xDrive50d by gaining a small, electric turbo to help increase low-end boost. It is also possible that BMW has simply just added a fourth conventional, gas-driven turbocharger.

Along with debuting in a new M750d model, the German automaker will also use the new diesel engine in M Performance variants of the X5 xDrive50d, X6 xDrive50d and X7 xDrive50d. Unfortunately based on BMW’s current offerings, it’s unlikely the quad-turbo engine will make its way to the U.S., although if diesel sales continue to improve, BMW might reconsider.
