If you thought the Audi RS5 didn't deliver enough of a hair-raising experience, you'll be pleased to hear the car maker has made it more split-end inducing by lopping the roof off.

Audi says the car will be one of the stars of this month's Paris Motor Show, thanks to the RS5 Cabriolet claiming the title of maddest drop-top to ever wear an RS badge.

The Cabriolet features something called a lightweight "acoustic hood". It's said this fabric top will offer similar levels of sound absorption to the RS5 Coupe, and will take 15 seconds to open and 17 to close. Posers will be pleased to hear it can be raised or lowed at up to 31mph too.

Two backseat passengers and their luggage can enjoy the ride, as the hood is not only good at deadening sound, but once lowered takes up minimal space in the boot.

Under the bonnet it's a familiar affair – 4.2-litres of V8 goodness. It's an engine that provides 448bhp, and can cover the 0-60mph sprint in just 4.7 seconds.

Earlier this year the RS5 Coupe received a subtle makeover to make it just that bit more imposing.

The Convertible benefits from this too, and the styling additions include a revised grille, "solid band" wrap-around LED daytime running lights and LED rear lamps, new bumpers and 19-inch alloys. Cabriolet models also boast a matt black boot spoiler.

Inside, like the revised Coupe, there's a new flat-bottomed steering wheel, Bluetooth, cruise control, sat nav and an iPod connection. But unlike its Coupe sibling, the Cabriolet sits 20mm lower and it has larger and firmer anti-roll bars.

Customer order books open later this year, and at the same time Audi will announce prices. We do know, however, it'll go on sale in Germany in 2013 costing a shade over £70,000.
