Aston Martin is lifting the lid on an extreme new sports car with the global debut of the V12 Vantage Roadster.

The new sports car, available as a limited edition in selected markets worldwide becomes the most potent example of the open-top Vantage range and mixes the power of Aston Martin’s 6.0-litre V12 engine with the established thrills of Vantage Roadster.

The V12 Vantage Roadster’s 6.0-litre engine, mated as in the Coupe to a six-speed manual gearbox, generates 517 PS at 6,500 rpm and a muscular 570 Nm of torque at 5,750 rpm.

The V12 provides high levels of power and torque yet it delivers a flexible, refined driving experience illuminated with the potential for truly electrifying performance. The 0-62 mph sprint is dispatched in 4.5 seconds while this most potent Aston Martin Roadster is capable of 190 mph.

The V12 Vantage Roadster features a redesigned rear boot lid and lower front air intake to maintain a level of dynamic performance that’s fully in keeping with the V12 Coupe, while there are also a number of unique chassis revisions. These include a modified rear damper set-up, front and rear damper valve tuning and a new rear spring design.

Inside, there are other distinguishing features that make the new car stand out from its illustrious siblings in the sought-after Aston Martin V8 Vantage and V12 Vantage line-up.

Unique to the V12 Vantage and new V12 Vantage Roadster is the engine’s “Sport” mode button, which enables the driver to select between two different powertrain modes.

Aston Martin chief executive officer Dr Ulrich Bez said: “The V12 Vantage models are, first and foremost, driver’s cars – inviting and fully rewarding the driver’s full involvement.

“The addition to our range of this exceptional new Roadster allows the driver and passenger to experience full ‘sensory overload’ thanks to its outstanding performance.”

He added: “I believe no other car in this class offers the combination of the V12 Vantage Roadster’s prestige, six-speed manual gearbox and the unique enjoyment that driving a high performance convertible can deliver.”

Available to order in selected markets now, the new Aston Martin V12 Vantage Roadster is priced at £150,000 RRP in the UK.
