B2K Returns
Earlier this year, Reeves Callaway unveiled a 25th Anniversary Callaway Corvette at the National Corvette Museum. Only 26 of these special-edition C6s have since been constructed (one for each year, plus a pilot car), all of which will be sold through the Callaway dealer network. With the exception of the #00 pilot vehicle, the run—consisting exclusively of Cyber Gray Grand Sport coupes and convertibles—was built in sequence at the Bowling Green Assembly Plant, then delivered to a Callaway facility for completion. Many had been pre-sold at press time.

In recognition of Callaway's contribution to Corvette development, Chevrolet reinstated RPO B2K for these cars. Originally assigned to the '87-'91 Callaway twin-turbo Corvettes, it's the only RPO GM has ever issued to an outside manufacturer.

The engine in the 25th Anniversary cars develops 620 hp—a 14hp increase over the standard supercharged Callaway Corvette. An Eaton TVS2300 blower and upgraded fuel system provide the bulk of the increase, while aluminum 1.80:1 rocker arms, specific valvesprings, and pushrods increase the redline to 6,700 rpm. To support the increased manifold pressure, high-tensile-strength head studs and fasteners replace the OEM bolts. Quarter-mile acceleration is rated at a ZR1-slaying 10.9 seconds at 127 mph.

The chassis includes Nürburgring- developed dampers built to Callaway specs by Bilstein. The carbon splitter, rocker panels, and rear spoiler, meanwhile, are manufactured by Callaway. Each car's interior includes a plaque identifying it as a 25th Anniversary edition.

The result is a wolf in sheep's clothing that's equally at home cruising to the store or tearing up the racetrack. The new B2K carries a three-year/36,000-limited warranty (a five-year/100,000-mile powertrain service contract is optional) and an MSRP of $52,980 on top of the price of the car.
