My Xterra is pretty damn fast....Ive raced and kept up with:

A Chevrolet Silverado SS- i was in his blind spot the whole time but we accelerated at the same rate

A BMW X5 4.8is- (yes he was getting on it) this time he stayed in my blind spot the whole time andwe accelerated at the same rate

A brand new Dodge Ram Daytona edition with HEMI- we were dead even the whole time

A BMW 1998 328is manual 2 door- I left him in the dust

A G35 4 Door sedan- this was on the highway we were dead even until I topped out at 114 (I think the G goes to 130 or something)

My mom has a 2003 Infiniti I35 and I think mine is faster...and Ive raced an Audi A4 2.0T in her car and beat it so that leads me to think I can beat most Audis that have the 2.0t engine. All of these races were done to maximize acceleration i.e. brake torquing and manually shifting into first then second gear to shift at the redline.
