The 1991 model year marked a significant evolution for the Chevrolet Corvette, particularly for enthusiasts of the high-performance ZR1 variant. While the 1990 Corvette introduced the world to the formidable ZR1, 1991 was the year many of its striking exterior enhancements trickled down to the standard C4 Corvette lineup, creating a more unified and modern aesthetic across the range.
One of the most noticeable changes for the 1991 Corvette was the redesigned front fascia. The parking lights were no longer separate units but were integrated into a wraparound design that flowed seamlessly around the front corners of the car. This subtle yet effective update provided a smoother, more contemporary look. Additionally, the vent design located just behind the front wheels was refined, further contributing to the updated styling.
Around the sides of the vehicle, the “belt” line, a trim piece that encircled the car, now adopted the body color, creating a more cohesive and streamlined profile. Moving to the rear, the 1991 Corvette saw a departure from the concave rear end and circular taillights of the 1990 model. Borrowing cues directly from the ZR1, the standard Corvette now featured a convex rear end and rectangular taillights. This change not only modernized the rear appearance but also visually linked the base model more closely to its high-performance sibling, the Corvette ZR1. Even the wheels for the base model Corvette received a fresh design, the introduction of the distinctive “saw blade” wheels adding another layer of visual appeal.
Beyond aesthetics, the 1991 Corvette also saw enhancements in performance and handling options. Chevrolet combined the Z51 performance package and the FX3 adjustable ride control to create a new Regular Production Option (RPO) code: Z07. This package was designed for drivers seeking maximum handling prowess, offering suspension settings that ranged from “stiff” to “very stiff,” catering to those with a penchant for spirited driving and track days. Understanding the demands of high-performance driving, an oil pan float was incorporated to provide a warning to the driver in low oil situations, a practical addition for those pushing their Corvettes to the limit.
Inside the cabin, the 1991 Corvette also incorporated some welcome convenience features. Reflecting the burgeoning mobile technology of the era, an accessory power wire was included, intended for items like early cell phones – a forward-thinking touch for 1991! Another user-friendly addition was a power delay feature, allowing occupants to operate the radio and power windows for a short period after the engine was turned off, enhancing everyday usability.
Notably, 1991 represented the final year for the B2K Callaway Twin Turbo Corvette option directly through authorized dealers. For Corvette enthusiasts seeking truly exceptional power, cars could be sent to Callaway Engineering for extensive modifications, resulting in twin-turbocharged monsters boasting up to 450 horsepower in later iterations of this special conversion. These Callaway Corvettes are highly sought after by collectors today.
Despite these updates and performance options, 1991 was one of the slower sales years for the C4 generation Corvette, with just over 20,000 units sold. Within this production run, the Callaway Corvettes and Z07 Corvettes were produced in even smaller numbers, with only 63 Callaway Corvettes and 733 Z07 Corvettes manufactured in 1991. These low production figures contribute to the rarity of these specific versions today, making both the 1991 Callaway and Z07 Corvettes particularly desirable and valuable within the classic Corvette market.
