Ready? Good. It's the brand new Aston Martin V12 Vantage S Roadster; an Aston that uses the excellent recipe of small car, huge engine and rear-wheel drive. And as you can see, it's a pretty, squat little thing. It's also really fast.

Well, fast for an Aston, anyway. It's basically the V12 Vantage S without a roof, and in doing so becomes the fastest-accelerating Aston roadster ever built. In fact, why not have a listen to it accelerate?

This oomph is thanks to the same ‘AM28' 6-litre V12 that features in the V12 Vantage S coupe. And because the roof comes down, you can revel in the noise of that simply marvellous engine even more.

You're looking at a nice, hefty 565 horsepower and 457 pound-feet of torque, all marshalled through the same Sportshift III seven-speed automated manual gearbox as the coupe (and replacing the six-speed manual from the last V12 Vantage Roadster), driving the rear wheels.

It'll go from zero to 60mph in 3.9 seconds and top out at 201mph. Not too shabby. The V12 Vantage S coupe, for reference, does the 0-60mph sprint in 3.7 seconds.

It's still the aluminium VH chassis underneath, there is still an adaptive damping system that cycles through three, self-explanatory modes (normal, sport and track), carbon ceramic brake discs all round, a new lightweight exhaust system and good, old fashioned hydraulic steering.

No mention is made of how long it takes to open and close the roof and at what speeds, but really, do you actually care about this? It's a drop-top Aston Martin with a massive, noisy V12.

Pricing hasn’t been announced, but expect a substantial upgrade from the coupe’s starting figure, which in the US is a not-inconsiderable $185,000.
