At the 2006 Greater Los Angeles Auto Show, Aston Martin officially unveiled the V8 Vantage Roadster.
The car gained 100 kg (220 lb) over the coupé, but Aston Martin claimed the car would have the same performance as the coupé.
To compensate for the loss of the roof a new, super-stiff cross-member was added to the frame.
The soft top could be raised or lowered electronically in 18 seconds and could be operated at speeds up to 30 mph (48 km/h).

It had the same 4.3-litre V8 from the coupé version producing 380 bhp (283 kW; 385 PS) at 7,000 rpm and 302 lb⋅ft (409 N⋅m) of torque at 5,000 rpm along with having a maximum speed of 175 mph (282 km/h).
It would accelerate from 0 to 60 mph (97 km/h) in 4.8 seconds.
The 2009 Vantage Roadster features swan wing doors, a leather and alcantara interior and a zinc alloy centre console and a crystal-capped key fob.
It also featured the updated 4.7-litre V8 which produces 420 bhp (313 kW; 426 PS) and 470 N⋅m (347 lb⋅ft) of torque, and can accelerate from 0 to 60 mph (97 km/h) in 4.5 seconds before reaching a top speed of 180 mph (290 km/h).
