First off, this isn't a racing story. I was in the far left lane on the freeway behind someone else. I see a Range Rover in the rear view. Not exactly riding my bumper, but a little close than I'd prefer. I was coming up on my exit, so I punch it and get over (nice day so I figured I'd let her breathe a little). Apparently he punched it too, because he was hanging in there. I got off and we parted ways, and that was it, but this led to some Googling when I got home. Guess these things are pretty fast
I'm thinking it was probably one of the sport models, supercharged and with 510 HP. Damn! Not bad for an SUV.
