Two great things to report. One, Aston Martin is manufacturing a V12 version of the extremely fetching Vantage sports car. It will be the most powerful road car the company has ever made, thanks to a 6.0-liter engine pushing 517 hp and 420 lb-ft of torque. Zero to 60 mph zips by in a mere 4.2 seconds and the top speed is set at 190 mph. The second piece of glad tidings: It's coming to North America later this year. A special Carbon Black edition will be available from launch. Just one worrying thing: Aston Martin hasn't announced any prices yet.
