1992 Callaway SuperNatural (SNAT)

Chevrolet's introduction of the LT1 in 1992 as the base engine in the Corvette phased out the L98 based Callaway Twin Turbo. Previously, Callaway Corvettes made their increased power through positive manifold pressure; now they made it through increased displacement and finesse. Initially called the CL1 or CR1, they designated the chassis they were built upon. They were based on the pushrod LT1 cars (CL1) or the 32 valve DOHC LT5 ZR-1 cars (CR1) and were available with a host of options. These included the familiar Aerobody, special paint colors, a full leather interior as seen previously on the Speedsters, special wheels, brakes, and exhausts round out the list. Cars could either be ordered and shipped directly to Callaway's facility in Old Lyme or a select authorized installer for installation or, an existing Corvette could be sent to them for conversion.

Along with the SuperNatural engines, Callaway has engineered a series of performance and appearance enhancements for the Corvette which make it the premier high performance road car in the world.

Based on the famous Callaway Sledgehammer, this Aerobody was for sale for B2K and SuperNatural owners (the Aerobody on this photo is actually a B2K Twin Turbo).

Available between 1992 and 1996, the Supernatural Series output constantly evolved. Introduced as a Supernatural 400, designating 400 horsepower, it grew to become the 425, 435, 440, and finally the 450 models for LT1 based cars and the 475 or 490 being offered for the LT5 models. The Supernatural line was a great success, with Callaway expanding it to the Camaro and Impala lines with similar options. It should also be noted; three very special cars were also constructed during this time, based upon LT5 models. It seemed natural for Callaway to turbo charge the LT5 and on three occasions, he did. Two Super Speedsters were built and one coupe, each unique in their own way.

Bridging the Twin Turbo and SuperNatural programs was the Callaway Speedster, Callaway's first vehicle identifiable completely as a Callaway. First offered as a Twin Turbo, Speedsters were now based on the LT1 and on the ZR-1 using the 4-cam LT5 powerplant. The ZR-1 Speedster line includes the twin turbocharged 750 hp Super Speedster.

Based on the Aerobody were the Callaway Le Mans cars:
