Corvette specialist Callaway is set to unveil its latest C16 Speedster flagship at next month’s Pebble Beach Concours d'Elegance, the third model in the C16 lineup joining the coupe and cabrio. The unique roadster features a 700hp supercharged 6.2L V8 engine, and a chopped roof with only a pair of small wind deflectors and extended headrests protruding from the smooth wedge shaped body.

The hand-built all-alloy powerplant develops an earth shattering 660lb-ft of torque, which should see the C16 Speedster reach 60mph from rest in just over three seconds with a top speed in excess of 200mph. To ensure all that power gets to the group, engineers have added an Eibach Multi-Pro coil-over suspension system adjustable to ten different settings.

Other high-end features include Dymag Carbon wheels with a forged magnesium spider-pattern. Measuring 19in up front and 20in at the rear, the unique wheels house six-piston callipers in the front and bite 355mm rotors. The new Speedster officially goes on sale in autumn and is priced at $305,000. One lucky buyer will get the car with build-plate No. 1 at the Concours d'Elegance on the 19th of August.
