Yahoo Autos Aston Martin V12 Vantage Roadster revealed with 690 horsepower
Aston Martin kicked off the week with one V12 convertible, and it's finishing it out with yet another one. But unlike the DBR22, the V12 Vantage Roadster has a folding soft top and will be available at the end of the year. It's not quite as powerful as the DBR22, but it's no slouch, and is practically as fast as its coupe twin.
Performance upgrades to the V12 Vantage Roadster are essentially identical to the coupe. It has a twin-turbo 5.2-liter V12 making 690 horsepower and 555 pound-feet of torque. Power goes through an eight-speed automatic transmission to a mechanical rear differential. In practice, the Roadster reaches the same 200-mph top speed as the coupe, and it's only 0.1 second behind it to 60 mph at 3.5 seconds.
