Aston Martin knows how to crank out the variants like few others automakers. With essentially two model lines in production, the British sportscar marque always seems to have another new model to debut. And the next looks to be the V12 Vantage Roadster.

Joining the limited-edition V12 Vantage coupe and its endurance racing counterpart, the muscle-bound drop-top should carry over the 510-hp 6.0-liter twelve, but trade a couple of ticks off the coupe's 4.2-second 0-60 time in exchange for the open-air experience. With barely-disguised test mules already spied, sources suggest the V12 Vantage Roadster is being prepared for its debut at the upcoming Frankfurt Motor Show in September.
