2012 Callaway 25th Anniversary Limited Edition Corvette

2012 RPO B2K Callaway 25th Anniversary Limited Edition Corvette

To commemorate its quarter-century milestone, Callaway Cars collaborated with Chevrolet, arranging a production run of 25 uniquely prepared 2012 Corvette Grand Sport coupes and convertibles. General Motors supplied special parts and procedures on the Bowling Green production line to facilitate final assembly at Callaway factories. Then, the performance and identity components are installed by Callaway.

The 25th Anniversary Limited Edition Callaway Corvette produced 620 bhp and 555 lb-ft of torque, the most ever produced by any LS3-powered Callaway Corvette. Quarter-mile acceleration was validated at 10.9 seconds at 127 mph. As the ultimate tribute, Chevrolet reinstated RPO (Regular Production Option) B2K, the same designation originally assigned to the 1987-1991 Callaway Twin Turbo Corvette option and the only Corvette RPO ever issued for a non-GM manufacturer.
