I got in trouble mistaking a cayanne for a toureg the other day. I'm on the ramp that transitions 285 W to 85 N (Spaghetti Junction for those familiar with Atlanta) in my CRX. As this ramp is a nice smooth radius with decent banking I usually take this opportunity to do a bit of passing. I pass a few cars in the outside lane and then come up on what I thought was a toureg. I switch to the inside lane and proceed to pass it at a healthy pace. I was about a car length in front of the "toureg" when we straightend out, and I was at the top of third and accelerating quickly. I try to get over and that damn toureg is keeping up. WTF?! With my lane quickly ending and about a car length still existing, I got over and settled down to about 70. The "toureg" hopped over a lane and kept it floored. As he passed me I saw the Cayanne S logo. "Oh - that explains it..."
I still don't like them, but they aren't slow.
