I thought it was impossible but it happened, I was rushing home from a trip up in San Francisco and I was clocked going 83 MPH up hill through the grapevine... I was surprised I was going that fast (in 4th gear) the pedal had a lot more room to go even faster.... These cars aren't as slow as you think!
