Corvette ZR1's Performance Figures Announced

THAT'S A CORVETTE ZR1. SEEN IT...True, but the official performance figures have been released. Curious?GO ON THEN...First off, the price. At €103,300 in the U.S. it's something of a performance bargain. A 480hp Porsche 911 Turbo costs $126,000 over there.THAT'S NOT THAT CHEAP.Perhaps not, but how much would a hand-built, supercharged, 6.2-litre V8 producing 647hp and 819Nm with a Porsche badge on it cost?AH, TOUCHÉ! SO HOW FAST IS IT?0-100km/h is dispatched in 3.5 seconds and top speed is 330 km/h. 0-160km/h takes seven seconds dead. That's quick.AUTOMATIC I SUPPOSE...Surprisingly, no. It's got six-speed manual transmission with race-hardened gears and a dual-disc clutch. It has a see-through bonnet, though, which is naff.NOT TERRIBLY GREEN, NOW IS IT?GM's engineers expect the ZR1 to be the most fuel-efficient 600hp+ car on the market, which is a bit like saying someone's the nicest axe murder you could possibly meet.
