The engine started, and I don't remember much of what followed, other than the feeling of being absolutely consumed. I exited with shaky hands, dribbling expletives and drool.
Here's what I do remember: At the end of our day, when no one was looking, I hopped in the P1 with our VBox data recorder. I slowly drove out of view to the far end of the runway (nothing to see here, folks), activated race mode, waited the required 40 seconds for the suspension to lower 2.0 inches and wing to rise 11.8 inches, and then activated launch control.
Then I was going 160 mph.
Here's what happened: The P1 took 2.6 seconds to reach 60 mph, 4.8 to 100, 6.4 to 120, and then passed the quarter mile in 9.8 seconds at 148.9 mph. Forget the Veyron. The P1 is the quickest production car tested in Motor Trend's 65-year history.
