The LS1 V8 engine is potent. It produces 345 horsepower and 350 foot-pounds of torque. Automatic or stick, the new Vette is fast traffic. It's quick at the starting gate, beautifully balanced, surprisingly comfortable, and built to a far higher standard than any Corvette in history. While we prefer the 6-speed that came on our car, we have to admit that the automatic rams its shifts home with authority, and there's enough muscle in the new V8 to cover the small performance penalties associated with auto-shifters.Unlike most ragtops, the Corvette convertible weighs the same as the coupe, which means its acceleration performance is undiluted: 0-to-60 mph in less than 5 seconds with the 6-speed manual transmission, about 0.4 seconds slower with the automatic. The only performance penalty that goes with the convertible version is top speed. The ragtop doesn't share the coupe's aerodynamic efficiency, so it tops out at a mere 162 mph versus 174 mph for the coupe. Of course, when the top is down there's more drag and a correspondingly lower top speed. Still, that's speed that'll get you to the drive-in in a pretty big hurry -- and the local slammer even faster. From a handling and acceleration standpoint, it's tough to perceive any performance distinctions between coupe and convertible. Corvette's chief engineer said the structural design for the new Vette began with the convertible, and as a consequence no shoring-up measures were required for the soft-top chassis. You hear the same song from almost every purveyor of convertibles, but in this application it seems to be true. If there's any distinction to be made between the agility and stability of the Corvette coupe and the new convertible, it would be all but impossible to discern on public roads. Even with the basic suspension package, our test car's responses were surgically precise, if you can imagine a surgical instrument with 345 horsepower and great gobs of torque. The Corvette offered sharp reflexes while driving down rural roads in Maryland. It provides a superb blend of muscle and finesse, with a much higher tolerance for mistakes of the enthusiastic variety, complemented by brakes that are nothing short of raceworthy. Just as important, there wasn't a hint of cowl shake, the time-honored malady of convertibles wherein the dashboard and exterior oscillate at differing rates. Ride quality is decidedly stiff. You don't get a sports car's ability to change directions without snubbing body roll and limiting up and down suspension motions, and when you do those things you're obliged to accept some tradeoff in comfort. Potholes in and around Washington, D.C., were easily identifiable in the Corvette. Yet they were not uncomfortably harsh. We heard them and felt them, but they weren't jarring and did not unduly upset the handling balance. |
