Test-Driving Porsche 911 Turbo Cabriolet: 480 Horsepower

Sept. 10

By Bruce Gain

STUTTGART, Germany -- Dawn is breaking as I turn onto the autobahn south of Stuttgart behind the wheel of Porsche's new 911 Turbo Cabriolet, which has just gone on sale in the United States.

I hit the gas, and in less than four seconds, I've blasted from standstill to more than 62 mph -- something you'd normally need a sports motorcycle to do.

In about 13 seconds, I'm racing at over 125 mph -- and then I realize I'm only in fourth gear. A few seconds later, I'm briefly cruising at about 170 mph in fifth gear, with plenty of room to go before reaching the max speed of 192 mph. However, one emotion prevents me from taking the car up to the sixth and highest gear: fear.
