Aston Martin and Red Bull are joining forces to build the world's fastest road car, which boasts the unwieldy working title of “AM-RB001”. Aston claims the new car will be faster than a Formula One race car, while Red Bull Team Principal Christian Horner said it will be “the ultimate of all road cars."

Red Bull Racing's chief designer Adrian Newey and Aston design head Marek Reichman will collaborate on the ambitious project, which will be designed with complete access to Red Bull's technological prowess, before being engineered by Aston's Special Operations unit.

In terms of how it might look, we only have a sweeping concept image to go on. We’ll have to wait until 2018 to see the final vehicle, of which only 100 will be built. And if the limited run doesn't make it a tricky motor to get hold of, the £1.8m-plus price tag will.

But while the boffins at Red Bull and Aston are busy making their new super car, we thought we'd look at the current top 10 fastest road cars on the planet...

  1. Bugatti Veyron Super Sport (268mph)
