The very limited Aston Martin Vantage GT12 now has a convertible variant after the Gaydon-based automaker revealed the Vantage GT12 Roadster at this year's Goodwood Festival of Speed. It won't be going into factory production however as this particular model was custom-made for a special client that wanted to have a Vantage GT12 with the benefit of open-top motoring.

“Aston Martin has a growing reputation of building ambitious commissions for customers, perhaps the best example being the spectacular CC100 Speedster Concept. We have also become world leaders in ultra-low volume projects with cars such as the One-77, Lagonda Taraf and Aston Martin Vulcan, while the Vantage GT12 and Vantage GT8 show how far we can take our series production models,” said David King, vice president and chief special operations officer in Aston Martin.

It was developed and delivered within a nine-month period by the company's in-house customization firm, Q by Aston Martin. Compared to the standard coupe, the Vantage GT12 Roadster gets new carbon fiber body panels, along with a line of custom paint finishes and trim pieces.

All the while, the Roadster still gets the same bodykit from the coupe version except for the large rear wing which has been removed. The integrated duckbill spoiler however has been retained.

Inside the Vantage GT12 Roadster

Powering the Vantage GT12 Roadster is the carried-over 6.0-liter V12 which produces 600 PS along with 625 Nm of torque. It is then mated to a 7-speed Sportshift III semi-automatic gearbox that drives the rear wheels. Other technologies installed on the Vantage GT12 Roadster are: magnesium inlet manifolds, lightweight magnesium torque tube and a full titanium exhaust system.

Unique to the convertible is a custom-tuned suspension system. Developed in-house by Aston Martin engineers, it allows the Roadster to have the same handling prowess of its coupe counterpart.

“The Vantage GT12 Roadster is a hugely exciting project. Not just because it’s sensational to look at, but because it vividly demonstrates the expanded capabilities of Q by Aston Martin. By incorporating the exceptional engineering capabilities of Aston Martin Advanced Operations within the Q by Aston Martin bespoke commissioning service we have a truly formidable creative team,” said Dr. Andy Palmer, CEO of Aston Martin.
