Brand Overview

Reeves Callaway founded Callaway Cars in 1977 with a focus on turbocharging Alfa Romeos before pivoting to Corvettes in the 1980s. The pivotal moment came when Callaway became an official GM RPO (Regular Production Option) — meaning buyers could order a Callaway Corvette directly from a Chevrolet dealer and have it included on the window sticker. This factory-direct distribution model set Callaway apart from all other Corvette modifiers.

Current lineup: The SuperNatural C8 (600 hp) and SC757 (757 hp) packages are available through authorized Chevrolet dealers as RPO B2K. The SC757 Z06 package pushes beyond 800 hp from the C8 Z06's flat-plane V8. Warranty: Callaway packages include Callaway's own limited warranty, and GM's base vehicle warranty typically remains in effect on non-modified components. Verify specifics at callawaycars.com. AeroWagen: Callaway's signature shooting-brake body conversion remains one of the most distinctive designs in American automotive history.

Reliability

Callaway Cars reliability varies by model and powertrain. Low-volume specialty manufacturers have less third-party reliability data than major OEMs — verified owner feedback and long-term durability data is limited. Verify with current Consumer Reports and J.D. Power ratings before purchasing.

Buying Tips 2026

Callaway's RPO distribution through Chevrolet dealers is a significant advantage — you can finance, insure, and title a Callaway Corvette as a factory product with dealer support. The SC757 adds considerable power to an already strong platform; buyers who plan to track the car should budget for appropriate tire, brake, and cooling maintenance. For used C7 AeroWagen examples, the shooting-brake body conversion adds value but also limits body shop expertise — plan for Callaway-certified shops for any bodywork.

Before You Buy — Checklist

1. Order through a Callaway-authorized Chevrolet dealer using RPO B2K for factory-certified purchase. 2. Verify warranty terms — Callaway warranty plus remaining GM base warranty. 3. Check nhtsa.gov/recalls with VIN for any GM base recalls. 4. For SC757 and Z06 packages: plan premium service intervals — 757+ hp demands meticulous upkeep. 5. For used AeroWagen: verify body integrity and find a Callaway-certified body shop before committing.

FAQ

What is RPO B2K?
RPO B2K is Chevrolet's Regular Production Option code for Callaway Cars upgrades. It allows buyers to order a Callaway-modified Corvette directly through a Chevrolet dealership, with the Callaway package included on the window sticker — just like any other factory option.
How much horsepower does the Callaway SC757 produce?
The Callaway SC757 package, applied to the C8 Corvette Stingray, produces 757 horsepower through a Callaway-developed supercharger system. The SC757 Z06 package applied to the C8 Z06 pushes beyond 800 hp.
Does Callaway void the Corvette warranty?
Not entirely. GM's base vehicle warranty typically remains in effect on components not affected by Callaway's modifications. Callaway provides its own warranty on modification components. The specifics depend on the package — verify at callawaycars.com before purchasing.
What is the Callaway AeroWagen?
The AeroWagen is Callaway's signature body conversion that transforms the Corvette into a shooting-brake (fastback hatchback) style. Originally offered on the C6 and C7, the AeroWagen has become one of Callaway's most recognizable and collectible modifications. A C8 version has been confirmed.
Is Callaway still making Corvette packages?
Yes, as of 2026. Callaway Cars remains active and continues to offer supercharger upgrade packages for the C8 Corvette Stingray, C8 Z06, and increasingly the C8 E-Ray hybrid.
