these BMW twin turbos are marvels of engineering, 567 horsepowers. The best engine BMW has ever made.

This engine allows you to have a huge family hauler (BMW X7) and drive like a BMW M3 like you stole it. Imagine hauling 3 kids and ski gear for 5 people up the twisty mountain road in the Sierras.

and by the way on the highway, X7 M60i gets you 21 mpg on the road. Amazing feat by the German engineers.

and I never had do top off the oil, just change oil every 7500 miles. Zero oil leaks. All of the notorious BMW V8 twin turbo issues were related to the early design and were solved in N63TU in 2014. The engines are rock solid, but the car has other weak parts (transfer case and front diff)
