Hardtop Convertible Vette Takes Shape

General Motors Co. has taken the wraps off the drop-top variant of its all-new Chevrolet Corvette Stingray, which is the first hardtop convertible in the nameplate’s history.

The retractable two-piece hardtop is powered by six electric motors, which GM says makes it more reliable than hydraulic units. The top can be lowered or raised in 16 seconds at vehicles speeds as great as 30 mph.

The composite top stows under a tonneau cover behind the seats—above the engine in the new mid-engine layout. The compartment is protected by heat shields and a cooling vent. A rear divider glass can be raised to reduce cabin wind.

GM notes the hardtop provides a quieter cabin, cleaner styling and increased security compared with typical soft-top designs. Aerodynamic differences are said to be negligible with the top up. The car’s trunk can still accommodate two sets of golf clubs with the top down.

The convertible system, motors and lowering mechanisms add about 80 lbs to the car. Spring and damper settings were adjusted to handle the extra mass.

The convertible’s interior and powertrain are the same as in the base coupe. This includes a 6.2-liter V-8 mated with an 8-speed dual-clutch transmission.

Chevy expects the convertible, which will be launched early next year, to account for about half of Corvette sales. Pricing will start at $67,500, which is a $7,500 premium over the coupe.
