If you think hybrids have to be dull, you're clearly not up to speed on Porsche's 918 Spyder ($845,000), which Patrick Dempsey recently test-drove at the Pebble Beach Concours d'Elegance.

"It's a remarkable car," he says of the 762 horsepower, all wheel-drive, gas/electric hybrid. "It's so quiet, it just moves along.... But when you get on it, the thing just roars to life."

Dempsey reckons the 12.9-mile German roller coaster known as the Nürburgring Nordschleife would be the ultimate place to test the 918 Spyder's limits. Just don't expect him to plunk down the cash for the exotic anytime soon. "I would love to order one," he explains, "but I've been spending too much money on racing to buy a 918."
