The Chevrolet Camaro Z/28: Trans-Am Dominance

The Chevrolet Camaro Z/28 is a legendary American muscle car that has left an indelible mark on the world of motorsports. With its powerful engine, aerodynamic design, and exceptional performance, the Z/28 has dominated the Trans-Am racing series for decades. In this article, we will delve into the history of the Camaro Z/28 and explore its unrivaled success in the Trans-Am championship. From its inception to its latest iteration, we will examine the key features and innovations that have made the Z/28 a force to be reckoned with on the racetrack.

The Birth of a Legend

The Chevrolet Camaro Z/28 was first introduced in 1967 as a high-performance variant of the Camaro. It was specifically designed to compete in the Sports Car Club of America’s (SCCA) Trans-American Sedan Championship, commonly known as the Trans-Am. The Trans-Am series was a highly competitive racing championship that pitted American muscle cars against each other on various road courses across the United States.

Under the hood, the original Z/28 featured a 4.9-liter V8 engine, known as the “DZ 302.” This engine was a masterpiece of engineering, combining a small displacement with high-revving capabilities. It produced an impressive 290 horsepower and 290 lb-ft of torque, making it a formidable competitor on the racetrack.

One of the key factors that set the Z/28 apart from its competitors was its lightweight construction. Chevrolet engineers stripped the car of unnecessary weight, removing features such as sound deadening material, power windows, and even the back seat. This weight reduction, combined with the powerful engine, gave the Z/28 a significant advantage in terms of acceleration and handling.

Trans-Am Dominance

From its debut in the Trans-Am series, the Chevrolet Camaro Z/28 quickly established itself as a dominant force on the racetrack. In its first year of competition, the Z/28 won 10 out of 13 races, securing the manufacturer’s championship for Chevrolet. This early success set the stage for the Z/28’s future dominance in the Trans-Am championship.

One of the key reasons for the Z/28’s success was its exceptional handling. The lightweight construction, combined with a finely-tuned suspension system, allowed the Z/28 to navigate tight corners and challenging road courses with ease. This gave the drivers a significant advantage over their competitors, allowing them to maintain higher speeds through corners and gain valuable time on the track.

Another factor that contributed to the Z/28’s dominance was its powerful engine. The DZ 302 V8 was a high-revving engine that produced its peak power at higher RPMs. This allowed the Z/28 to excel on tracks with long straightaways, where the engine could reach its full potential. The combination of power and handling made the Z/28 a formidable opponent in any race.

Innovations and Evolution

Over the years, the Chevrolet Camaro Z/28 has undergone several iterations and updates to stay competitive in the ever-evolving world of motorsports. Each new generation brought with it new innovations and improvements, further solidifying the Z/28’s dominance in the Trans-Am championship.

One of the notable innovations in the Z/28’s evolution was the introduction of fuel injection technology. In 1982, Chevrolet introduced fuel injection to the Z/28, replacing the carbureted engines of previous generations. This technology provided more precise fuel delivery and improved engine performance, giving the Z/28 an edge over its competitors.

Another significant development in the Z/28’s evolution was the introduction of aerodynamic enhancements. As the importance of aerodynamics in racing became more apparent, Chevrolet engineers worked to improve the Z/28’s aerodynamic efficiency. This included the addition of spoilers, air dams, and other aerodynamic features that reduced drag and improved stability at high speeds.

Furthermore, advancements in suspension technology and tire design have also played a crucial role in the Z/28’s success. Each new generation of the Z/28 has seen improvements in suspension geometry, shock absorbers, and tire compounds, allowing for better handling and increased grip on the racetrack.

Legacy and Impact

The Chevrolet Camaro Z/28’s dominance in the Trans-Am championship has left a lasting legacy in the world of motorsports. Its numerous victories and championship titles have solidified its place as one of the most successful American muscle cars in racing history.

Moreover, the innovations and advancements made in the Z/28 have had a significant impact on the automotive industry as a whole. Technologies such as fuel injection and aerodynamic enhancements, which were first introduced in the Z/28, have become standard features in modern performance cars.

The Z/28’s success on the racetrack has also helped to elevate the reputation of the Chevrolet Camaro as a whole. The Trans-Am victories have showcased the Camaro’s performance capabilities and have attracted a loyal fan base that continues to support the brand.


The Chevrolet Camaro Z/28’s dominance in the Trans-Am championship is a testament to its exceptional performance and engineering prowess. From its humble beginnings in 1967 to its latest iteration, the Z/28 has consistently outperformed its competitors on the racetrack.
