The Nissan-powered DeltaWing race car was on-hand for a few laps at Sebring this weekend, and the funky-looking speedster made it around the 3.7-mile track without incident.

The DeltaWing sports a direct-injection, 1.6-liter turbocharged Nissan engine making about 300 hp.

The soft-top flagship is the first convertible Aston with a carbon body, making the stiffest and most powerful drop-top it has ever built. Its 565bhp drivetrain has been taken straight from the Aston Martin Vanquish coupe – the most powerful Aston to date – but the Volante adds 105kg and an extra £6000 for a starting price of £199,995.
