What's the sense of having a hood with that kind of engine cover. Actually, I think it would look cooler to just take off the hood for that matter.

BMW Aztec?

No, that looks way better than an Aztec.

I was wondering the same thing

[d3ity]

What is it with BMW and ruining everything with the number 6 in it?

Seriously. They haven't done anything GOOD with the number 6 in it since the 1980s.

Aloha everyone,

That almost looks like they're trying to offer a "BMW solution" to the R-class from Mercedes.

^^ That's exactly what it is. I guess "alternative" is a more fitting word

To each their own. I am looking forward to seeing it on the road. Not a race car, but as a daily driver it looks a lot better than the X5 or the X3.

What is really ftw is the new positioning of the intake and exhaust manifolds and how they are going about the turbo-charging.

Do tell.

This is for the X6 xDrive50i. The two turbos are used one for each bank of 4 cylinders, ala -35i powered cars. BMW positioned the turbos and the catalytic converters in the valley of the V8. Instead of running the intake manifold to the inside of the V and having the exhaust manifold com out from the side of teh V ans is usually done, the intake comes from the sides, and the exhaust manifold goes to the turbos in the middle. This results in very short intake and exhaust manifold and, thus, reduced turbo lag (basic fluid dynamics -- yes, hot air is a fluid -- shorter manifolds means less pressure drop).

If you think about it, a lot of materials science and characterization research went into coming up with a design with turbos that maintain the intended functionality despite being in the hottest place in the car (not counting the inside of the engine).

Very innovative. Scientific American picked this car among one of the top-ten cars in terms of technological advances.

Oh, and the way the engine is configured... well, it fits in smaller places than one would expect for a 400 hp, 450 lb-ft powerplant

very interesting with the turbos.... i wanna get one of those things to toy with....

Why put the cats there? What purpose does it serve to have them there rather than further downstream where the excess heat they generate will not interfere with the engine's operation?
