That's as many as a Bugatti Veyron!
A few months ago, we were impressed when Audi unveiled the all-new SQ7. The SQ7 will be powered by a 4.0-liter V8 diesel engine with three turbochargers making 435 hp and 664 ft-lb of torque. We were impressed by the thought of a tri-turbo diesel, but now BMW had upped the ante. Bimmerpost reports that BMW has released a quad-turbo diesel engine. This engine is a 3.0-liter inline-six that will make 394 horsepower and 561 lb-ft of torque. It will first be offered on the 7 Series and get the car to 60 mph in around 4.5 seconds.
This new engine will replace the tri-turbo six-cylinder diesel engine that is in many current BMW products. After the 7 Series, the quad-turbo engine will find its way into M Performance vehicles like the X5 and X6 M50d. BMW says that this new engine has more power, better response, and a high revving capability that will make it a V8 fighter. BMW replaced the massive low pressure turbo from its tri-turbo engine with two smaller exhaust driven ones. This engine should be ready to go into battle with Audi's V8 and like that car, we probably won't ever get it in the US.
