Aston Martin Vantage models will soon be powered by way of a twin-turbo V-8 that produces over 500 horsepower, while a lucky few buyers can get a much more powerful twin-turbo V-12. Aston claims a zero-to-60 mph time of 3.4 seconds, which can be conservative. Unfortunately, the order book because of this special model is closed and only 333 units is likely to be produced.
