Spy Pics: Aston Martin Vantage GT12 Roadster Spotted Testing — No Longer A One-Off

Aston Martin unveiled a 'one-off' Vantage GT12 Roadster at the 2016 Goodwood Festival Of Speed, a drop-top version of the British carmaker's most hardcore road-legal car.

However, car spotters at the Nurburgring have spotted an Aston Martin test mule, with some rather familiar bodywork, which could suggest that the GT12 Roadster may soon loose that one-off tag.

The spied car spotted no camouflage but was painted black instead of the stealth gray paint job found on the car unveiled at Goodwood.

The limited edition GT12 roadster is expected to feature the same naturally aspirated V12 engine found on the Vantage GT12. The 6-litre V12 produces 595bhp and 625Nm of torque and is mated to a 7-speed automatic gearbox.

However, the drop-top GT12 is expected to be slower to 100km/h from standstill thanks to the extra weight added due to the electrically operated folding fabric roof. The top speed is also expected to take a hit as well.

One feature that we don't expect to make it onto the GT12 roadster from the Goodwood one-off is the titanium exhaust system, though it could be offered as an option.
