BMW has gotten my attention

BMW recently came out with a beautiful new 5 series. I know what you are thinking; big deal they do that every year. Well this year is different they have included a 535d, the "d" standing for diesel.
Why is this different from all the other diesels on the market?
For years people have put done diesels for being sluggish engines, so engineers threw a turbo on it and called it good. Critics still put them down saying "yeah they aren't as sluggish anymore, but now you have 2,000 rpms worth of "turbo lag" where you have to wait for the turbo to spool up in order to have power." This has all changed.
The engine in the 535d is a 3 liter inline 6 cylinder diesel that is accompanied by a bi-turbo system. The bi - turbo or multistage turbo works by having a big and small turbo; the small turbo spools quickly and is at full boost by 1500 rpms (no turbo lag) this is where the big turbo joins in to help out and generates the amazing 413 Ft lbs of torque. That's enough torque to rip a tree out of the ground. Still the car is a 4 door sedan, and one of the quietest diesels for sale, but that doesn't stop it from doing 0-60 mph in 6.5 seconds and averages 39.2 mpg on the highway.
