I purchased Road and Tracks Best Sports and GT cars issue yesterday. I was comparing weight and dimensions between the S7 and the Enzo (~3200 lbs) and I was surprised to see, the S7 (~2800 lbs) weighs 400 lbs less than the Enzo. Why? Other than the Enzo is a V12 and the S7 is a V8 I dont see much difference in size. By the way, the Enzo recorded the fastest ¼ mile at 11.1@133mph, it posted a 1.01g and did the (700 ft) slalom at 73mph. That quarter mile time is very impressive for a production car. The 133 mph shows how much this car will pull past the ¼ mile and/or from a roll. Oh and it record 3.24 secs from 0 to 60mph.
