I am in a 535 loaner that has the twin turbo 3.0 liter motor. Even with more weight than the 335 that motor pulls like there's no tomorrow. An incredible motor! Add another 1000 pounds to the automobile to get an X5 and I'm
sure it will still pull and pull and beg for more. There's not enough road for me to satisfy this engine's lust for speed!
If you haven't test driven a BMW with this motor under the hood, you're missing out on a thrilling experience. I'm also hoping the twin turbo V8 has the same development of power through the power band. It just swells!
