In July 1970, Car and Driver embarked on a defiant project: transforming a modest Opel GT into a statement against tightening regulations and bureaucratic overreach. The goal wasn’t just speed, but a middle finger to those dictating what drivers could enjoy. The original article, steeped in cynicism and fueled by the era’s counterculture, detailed how the staff systematically tweaked an unremarkable car into something genuinely electrifying.
The Problem: Fun Under Fire
By 1970, automotive enthusiasm was under siege. Emissions standards, insurance costs, and government interference made performance cars less accessible and more expensive. The writers at Car and Driver saw this as a deliberate stifling of freedom. Their solution wasn’t protest, but subversion: take a cheap, unassuming car and make it better without drawing unwanted attention. The Opel GT was chosen for its potential—a small, two-seater coupe with enough room for improvement.
The Execution: Under the Radar
The project wasn’t about outright power, but about efficiency. The engine was blueprinted, headers added, and compression tweaked to extract every possible horsepower without triggering regulatory alarms. The result? A modest but effective 100 hp—enough to surprise without attracting scrutiny. The real transformation came in handling. The stock Opel was criticized for its weak suspension and undersized tires. The team addressed this by installing aftermarket anti-roll bars and fitting oversized Goodyear Polyglas tires on Minilite wheels. This dramatically improved grip and balance, turning the GT into a nimble machine capable of unsettling Porsches.
The Philosophy: Engineering as Defiance
The project wasn’t just about modifying a car; it was about proving a point. The team deliberately flaunted regulations while staying within the bounds of legality. This was a calculated move. By working within the system, they could subvert it. The car became a symbol of automotive autonomy: fast, agile, and unrepentantly fun.
The Legacy: A Blueprint for Rebellion
The Car and Driver Opel GT project wasn’t just a one-off modification. It was a template for enthusiasts looking to reclaim control over their vehicles. The article’s emphasis on subtle upgrades, careful tuning, and a defiant spirit resonated with a generation of drivers frustrated by overregulation. Today, this approach remains relevant. The pursuit of performance doesn’t always require excess; sometimes, it just requires ingenuity.
The Opel GT project stands as a reminder that automotive freedom isn’t given—it’s earned through careful engineering and a refusal to compromise.
