The Genesis of the Opel GT: A Bold Move by GM in the 1960s
To fully appreciate the significance of the 1973 model year, one must understand the context of the Opel GT’s introduction. General Motors, through its German subsidiary Opel, had established a reputation for producing sensible, reliable, and economical vehicles throughout the 1950s and 1960s. While these cars, such as the Kadett and Rekord, were commercially successful, they lacked the excitement and aspirational appeal of their American counterparts. Recognizing the need for a halo car that could inject some sporting character into its lineup and compete with emerging European rivals like the Ford Capri, GM tasked its Opel design team with creating something special.
The inspiration for the Opel GT came from an unexpected source: a concept car that was never intended for production. At the 1965 Frankfurt Motor Show, Opel unveiled the Experimental GT, a stunning two-seater coupe that bore a striking resemblance to the Chevrolet Corvette, albeit in a much smaller, more refined package. The concept car’s design, spearheaded by Opel’s chief stylist Clare MacKichan (who also played a role in the iconic C2 Corvette’s design), captivated audiences with its flowing lines, long hood, short deck, and signature hidden headlights. The overwhelmingly positive reception to the Experimental GT convinced GM executives to greenlight a production version, marking a bold departure from Opel’s traditionally conservative image.
The production Opel GT finally debuted in 1968, five years after the concept’s unveiling. While the production model retained the core design elements of the concept—including the distinctive fastback silhouette and the innovative hidden headlights—it was built on the humble underpinnings of the Opel Kadett B. This decision to utilize existing, mass-produced components allowed Opel to keep development costs down and ensure that the GT could be produced efficiently and affordably. Despite its modest foundation, the GT possessed a visual presence that belied its underpinnings, offering a level of style and excitement that was previously unattainable in Opel’s product lineup.
Design Excellence: A Mini-Corvette with European Flair
One of the most enduring aspects of the Opel GT’s appeal is its exceptional design. In an era when many European sports coupes prioritized functional efficiency over aesthetic flair, the Opel GT stood out with its curvaceous bodywork and sophisticated proportions. The car’s most distinctive feature, and the one that earned it the “mini-Corvette” moniker, was its pair of rotating headlamps. Instead of the conventional pop-up headlights that were becoming increasingly popular on sports cars of the period, Opel’s engineers devised a unique crank-operated system that required the driver to manually rotate the entire headlamp housing to expose the lights. This intricate mechanism, while adding a touch of mechanical theater, contributed to the car’s sleek, uninterrupted profile when the lights were retracted.
Beyond the headlamps, the GT’s bodywork exuded a European sensibility that differentiated it from its American counterparts. The long, sloping hood, reminiscent of classic GT cars from marques like Jaguar and Ferrari, flowed seamlessly into a compact passenger cabin. The roofline tapered elegantly to a Kammback tail, a design feature that optimized aerodynamic efficiency while maintaining a sporty aesthetic. The car’s stance was low and wide, conveying a sense of agility and performance, even when standing still. The original color palette offered by Opel further enhanced the GT’s visual appeal, with vibrant hues like Rallye Gold, Mellow Yellow, and Rallye Green adorning many examples, making them unmistakable on the road.
While the interior space was understandably limited due to the car’s compact dimensions, Opel’s designers managed to create a driver-focused cockpit that prioritized functionality and driver engagement. The dashboard was dominated by two large, deeply recessed dials for the speedometer and tachometer, providing the driver with essential information at a glance. Additional gauges for oil pressure, water temperature, and fuel level were centrally located, ensuring that the driver remained fully informed about the car’s mechanical status. The seats, while perhaps lacking the bolstering of more modern sports cars, offered adequate support for spirited driving, and the three-spoke steering wheel provided a tactile connection to the road.
Engineering Ingenuity: The Kadett Foundation and the 1.9-liter Engine
Underneath its stunning exterior, the 1973 Opel GT was built upon the proven platform of the Opel Kadett B. This decision, while perhaps disappointing to some who might have hoped for a dedicated sports car chassis, was a pragmatic one that allowed GM to offer the GT at a competitive price point. The Kadett B chassis provided a solid foundation of rigidity and handling characteristics that were well-suited to the GT’s mission as a nimble European-style sports coupe. The suspension consisted of coil springs and hydraulic shock absorbers at all four corners, with independent suspension at the front and a live axle at the rear. This setup, refined through extensive testing, delivered a balance of ride comfort and handling prowess that made the GT an enjoyable companion on both winding back roads and everyday commutes.
The heart of the Opel GT was its 1.9-liter inline four-cylinder engine. Developed specifically for the GT, this engine was based on the robust powerplant found in the Kadett Rallye but received several enhancements to improve performance and responsiveness. In its 1973 configuration, the engine produced approximately 89 horsepower and 109 lb-ft of torque. While these figures may seem modest by contemporary standards, they were respectable for a car weighing just under 2,000 pounds. The engine’s relatively low weight and the GT’s aerodynamic bodywork allowed for brisk acceleration and a top speed of around 110 mph, which was more than sufficient for the European road network and provided plenty of excitement for American drivers.
The 1.9-liter engine was paired with a choice of two transmissions: a three-speed manual or a four-speed manual. For 1973, the four-speed manual was the standard offering, reflecting the growing preference among enthusiasts for greater driver control and engagement. The gearbox was known for its precise action and relatively short throws, allowing the driver to make quick and decisive gear changes. In contrast, the three-speed automatic was relegated to the option list, a clear indication that the Opel GT was primarily targeted at drivers who appreciated the interactive experience of a manual transmission. The combination of the rev-happy four-cylinder engine and the slick-shifting four-speed manual made the GT an engaging and rewarding car to drive, even by today’s standards.
Market Evolution: The 1973 Model Year and Beyond
The 1973 model year represented the final production run for the Opel GT. By this time, the car had established itself as a niche but respected player in the automotive landscape. While it never achieved the sales volumes of the Ford Capri or the widespread recognition of the Chevrolet Corvette, it carved out a dedicated following of enthusiasts who appreciated its unique blend of style, performance, and value. A total of approximately 103,000 Opel GTs were produced between 1968 and 1973, with a significant portion of those destined for the North American market through Buick dealerships.
The 1973 models benefited from the cumulative refinements made throughout the production run. Minor updates to the engine, suspension, and interior ensured that the final examples represented the best the GT had to offer. However, as the 1970s progressed and automotive regulations in the United States became increasingly stringent, the future of the Opel GT became uncertain. The car’s small engine displacement and lightweight construction made it particularly vulnerable to new emissions standards, which often favored larger, more powerful engines. Furthermore, the economic challenges of the 1973 oil crisis led to a general downturn in the market for sports cars, further complicating the GT’s prospects.
Despite its discontinuation in 1973, the Opel GT’s legacy endured. Owners cherished the car for its distinctive character and reliable performance, and a dedicated community of enthusiasts emerged to celebrate and preserve these unique vehicles. The GT’s rarity, combined with its undeniable charm, began to attract the attention of collectors in the decades that followed. While the car never reached the strat
