The 450 hp 2.9L twin-turbo six in the Audi RS5 is a compact powerhouse. But Audi only offers the RS5 as a coupe. And a real two-door one, not the four-door coupe kind. What if you want to enjoy power from Audi, but want to go topless? Or if you need more space for stuff and things?

ABT Sportsline has a pretty good solution for you. They've taken the S5 Cabriolet and boosted the 3.0L V6 from that car to 425 hp and 406 lb-ft. Not quite up to the RS5, but close enough. Twin 3.5-inch exhaust tips on an ABT rear muffler make sure that you'll be able to hear the exhaust, even with the wind in your ears.

To finish the look, the S5 Cabrio has ABT rear skirts with an aggressive rear diffuser. There's also a new front bumper to make sure your car stands out. ABT offers a range of 19 and 20-inch wheels to complete the look.

If you need more cargo space, the A5 Sportback gets a boost from 252 to 330 hp from the 2.0L four. That's from ABT engine control and a new exhaust.

ABT will have a height adjustable suspension kit available soon that can lower the A5 and S5 by 0.59 to 1.6-inches for cornering grip to match the power.
