Caparo T1 Breaks The 1,000 HP Per Ton Barrier, to Debut at Goodwood

If you've been dreaming about an F1 car you can drive to Starbucks, dream no further. Caparo will begin delivering their close to $400,000 track-day special in July. And the stats are just stoo-pid: 575 horsepower at 10,500 rpm from a 3.5-liter V8; zero to 60 mph in 2.5 seconds; 0-100 mph in less than five seconds. Top speed is rumored to be infinity and the brakes are so powerful the T1 goes slower than not moving (fine, 100-0 mph in 3.5 seconds). The biggest news of course is that Caparo, for the first time ever, is going beyond 1,000 hp per ton in a production vehicle. In fact, they have achieved the insane figure of 1,045 hp for every 2,000 lbs. Not a word about five-mile-per-hour bumpers, though. Completely bonkers specifics after the jump.
