On the street, the X6 xDrive 50i is smooth and stealthy fast. It coasts effortlessly--fast seems, well, slow. Triple-digit speeds sneak up so easily, the X6 could be a citation machine for the lead-footed. Floor it and the V-8 rewards with a cranium-filling sonic massage.

The X6 appears most like an X5 on the inside. Our loaded 50i had a thick, heated steering wheel and leather-trimmed kneepads for cornering. In the back, BMW's product-packaging magicians managed to squeeze in plenty of legroom and just enough rake in the seats so that six-footers with normal haircuts shouldn't have problems with the low roof. The cargo area is deep, but not tall--still enough for four golf bags, claims BMW.
