Launch a hardcore coupe and following it up with a hardcore convertible, a simple formula used by almost all high-end automakers. So when Aston Martin launched the Vantage GT12 back in 2015, many thought a drop-top version would soon follow but it never did. Until June’s Goodwood Festival of Speed.

At the UK’s biggest motoring event, the British marque released the GT12 Roadster but interestingly, it was a one-off creation produced by the firm’s Q personalization division for a wealthy client and not a production model. Or was it?

Despite that car being billed as a one-off, a GT12 Roadster prototype has just been snapped testing at the Nurburgring suggesting that the car received such a positive reaction that Aston has decided to put it into limited production.

If that’s indeed the case, we could just be months away from seeing a fully-fledged GT12 drop-top hitting the market with a screaming 6.0-liter naturally-aspirated V12 engine, sending off the marque’s all-motor powertrains with a bang. That means we could also be just months away from hearing about an annoyed collector who no longer owns a unique car.

So what’s going on here? Perhaps Aston Martin made an agreement with the commissioner of the ‘one-off’ GT12 Roadster that it was going to put the car into production? Or is this prototype testing something out entirely? Maybe a turbocharged engine from AMG?
