GMMG's 2002 ZL1 Camaro: A Rare 4th-Gen Muscle Car Inspired by the 1969 COPO Legend

What is a 2002 ZL1 Supercar Camaro?

A Modern Supercar With Legendary Roots

The GMMG ZL1 Supercar Camaro is a rare, high-performance fourth-generation Chevrolet Camaro that underwent extensive upgrades by GMMG, Inc., a performance tuning shop based in Marietta, Georgia. Created in 2002, this limited-edition Camaro was designed to commemorate the legendary 1969 COPO ZL1 Camaro, with just 69 cars produced—matching the original COPO ZL1 production total.

The ZL1 Supercar featured a powerful all-aluminum 427ci V8 engine and performance upgrades designed to deliver supercar-like performance. These cars also featured unique badging, striping, and specialized suspension components to enhance handling and speed. Many original owners also opted for custom paint, selecting heritage colors from 1969.

While Berger Chevrolet sold the largest quantity of ZL1 Supercars, with 28 of the 69 units, the remaining cars were sold through 12 other Chevrolet dealerships across the country. Each of these dealerships contributed to the exclusive distribution of this high-performance model, making the ZL1 Supercar even rarer.

Unlike the original COPO cars, the 4th-gen ZL1 Supercars were not built directly by General Motors but were instead standard Camaros that were modified by GMMG. These modifications were carried out to exacting standards, ensuring that each vehicle maintained GM's high-quality fit and finish while enhancing performance to supercar levels. They are not to be considered COPO Camaros.

Today, the GMMG ZL1 Supercar Camaro is considered one of the ultimate fourth-generation modified Camaros, revered for its performance, rarity, and historic connection to the Camaro legacy.

How many 2002 ZL1 Supercars were made by GMMG?

A total of 72 2002 ZL1 Supercar Camaros were produced by GMMG. The program began with three prototype vehicles, followed by a limited production run of 69 customer cars. This number was a deliberate homage to the original 1969 ZL1 Camaros, of which only 69 were built by Chevrolet, making the modern interpretation even more collectible.

Each car was built at GMMG’s Marietta, Georgia facility and received extensive performance and appearance upgrades. The 69-car run was distributed through 12 Chevrolet dealerships nationwide, with Berger Chevrolet selling the most—28 units in total.

What are the ZL1 Supercar specs?

The GMMG ZL1 Supercar Camaro is recognized for its extensive suite of modifications that set it apart as one of the most exclusive and high-performance fourth-generation Camaros ever produced. These cars were transformed from stock F-bodies into finely tuned muscle machines, blending performance, heritage styling, and collector-grade details.

Under the hood and throughout the chassis, GMMG made a series of high-impact upgrades aimed at maximizing performance. A cat-back chambered exhaust system with stainless steel tips gave the car a deep, aggressive tone and improved airflow. Handling was refined with Penske racing shocks and specially selected front and rear lowering springs, which dropped the ride height and enhanced road feel. To match the added performance, stopping power was dramatically improved with Corvette Z06 brake calipers and slotted Z06 rotors—components lifted directly from GM’s own performance icon.

Visually, the ZL1 Supercar featured numerous styling cues that paid tribute to the Camaro's muscle car roots. The exterior was fitted with a GM ‘SS’ hood and ‘SS’ rear spoiler, a hood, roof, and deck lid stripe package, and a 35th Anniversary satin black center hood decal. The front grille was finished in charcoal metallic and fitted with a 1969-style Bowtie emblem, while the rear panel was painted black and adorned with high-polished “Camaro” lettering for a classic, throwback look.

The interior didn’t go untouched either. Every car received a cloisonné HPT/TQ dash plaque, signifying its unique build and performance specs. A numbered GMMG door jamb plate was installed for authenticity, and silver face gauge inserts gave the instrument cluster a sportier, more refined appearance.

All together, these enhancements made the GMMG ZL1 Supercar Camaro a standout not only among fourth-gen Camaros but within the broader collector car world. It remains one of the most revered and sought-after modified Camaros of its era.

How much horsepower did the ZL1 Supercar make?

The GMMG ZL1 Supercar Camaro, a modern muscle car icon, offered a range of performance packages designed to meet the needs of enthusiasts looking for anything from street-friendly upgrades to full-track dominance. The packages were structured in distinct Phase levels, each offering escalating horsepower and performance improvements. Here’s a look at the packages and their corresponding horsepower ratings:

Phase 1: 400 Horsepower

The entry-level upgrade for the ZL1 Supercar, Phase 1, started with a 427ci engine (based on the LS6 block) that produced approximately 400 horsepower. This base performance package included a modified camshaft, upgraded exhaust, and an improved intake system, making the ZL1 a noticeable step up from the stock Camaro in both sound and power.

Phase 2: 475 Horsepower/440 lb-ft of torque

Phase 2 was where the ZL1 started to show its aggressive side. With a more aggressive camshaft, optimized tuning, and enhancements to the intake and exhaust systems, Phase 2 ZL1 Supercars produced around 475 horsepower, offering a sharper throttle response and quicker acceleration. This phase was ideal for buyers looking for a stronger, more exciting driving experience without going to the extreme.

Phase 3: 600 Horsepower/575 lb-ft of torque

Phase 3 ZL1 Supercars were the ultimate expression of performance. Equipped with a C5-R–based 427ci engine, these cars delivered a massive 600 horsepower—a major leap over the previous phases. Derived from GM’s Le Mans-winning Corvette C5-R race engine, this phase was built for serious enthusiasts seeking track-ready performance, offering incredible torque and high-revving capabilities that made Phase 3 ZL1s some of the most powerful and rare Camaros ever built.

Are 2002 GMMG ZL1 Supercar Camaros collectible?

Yes, 2002 GMMG ZL1 Supercar Camaros are highly collectible. With only 72 cars produced—including 3 prototypes and 69 production units—these limited-edition Camaros represent a rare chapter in fourth-generation F-body history. Each car received hand-finished performance and styling upgrades that significantly elevated its value, and many were delivered with low mileage and carefully preserved by enthusiasts from day one.

Their exclusivity, connection to the muscle car heritage, and unique blend of modern engineering with retro flair make them especially appealing to collectors. As awareness continues to grow, so does their desirability, cementing their place as one of the ultimate collector Camaros of the modern era.

How Much Is a 2002 GMMG ZL1 Supercar Camaro Worth Today?

The 2002 GMMG ZL1 Supercar Camaro has become one of the most collectible modern muscle cars, thanks to its extreme rarity, high-performance upgrades, and direct connection to fourth-generation Camaro history. With only 72 examples produced—three prototypes followed by 69 production cars—these cars are seldom seen for sale and are highly sought after by enthusiasts and collectors alike.

At past Mecum Auctions, select examples have crossed the block, further validating the car’s collectible status. Notably, ZL1 Supercars have brought between $80,000 and $150,000, depending on the specific phase, mileage, provenance, and original documentation. Rare versions—such as Phase III cars with 427ci engines or Dick Harrell tribute builds—can command even higher prices when they appear, which is increasingly rare.

Their consistent upward trend in value and limited production numbers have secured the GMMG ZL1’s place as one of the ultimate fourth-gen Camaro collectibles—and a must-have centerpiece for any serious American muscle collection.

Is the ZL1 Supercar street legal?

Yes, the GMMG ZL1 Camaros are street legal. These modern tribute cars were built using late-4th-gen Camaro SS models and upgraded by GMMG with performance, appearance, and handling enhancements — all while maintaining street-legal status. They passed emissions testing (at the time) and retained factory VINs, titles, and registration, making them legal for everyday road use. However, some high-horsepower variants might not comply with current emissions standards in stricter states.

More Than a Camaro

The ZL1 Supercar was more than just another Camaro—it was the boldest expression of GMMG’s capabilities. It merged modern LS power with COPO-inspired exclusivity, offering customers a bespoke performance machine that felt equally at home on the track or in a private collection.

As production of the fourth-gen Camaro wound down, the ZL1 Supercar became a fitting sendoff—closing the chapter on an era of dealer-backed tuner cars and cementing GMMG’s place in performance history.
