1990 General Motors Micro CDS-2 by Gérard Gauvr

The General Motors Micro CDS-2, introduced in 1990, was an experimental concept that explored the future of compact and efficient urban transportation. Designed by Gérard Gauvry, the CDS-2 embodied GM’s forward-thinking approach to lightweight vehicle engineering during a period when automakers were increasingly focused on fuel efficiency, reduced emissions, and urban mobility solutions. Its small size, aerodynamic shape, and advanced engine technology made it a standout in GM’s research portfolio of the late 20th century.

At the heart of the CDS-2 was a 1.5-liter, three-cylinder, two-stroke engine producing 110 horsepower—an impressive figure for such a small displacement. This engine showcased GM’s experimentation with two-stroke technology as a potential path to balancing power and efficiency. Unlike conventional four-stroke engines, the CDS-2’s design allowed for a higher power-to-weight ratio and smoother operation at lower engine speeds. Combined with the car’s lightweight construction, this powertrain aimed to deliver responsive performance while keeping fuel consumption to a minimum.

The “Micro” designation wasn’t just a marketing term; the CDS-2 was genuinely compact, designed for city driving and easy maneuverability. Its low-slung, futuristic body featured rounded contours and a minimalist cabin layout—common traits in early 1990s concept vehicles that prioritized aerodynamics and simplicity. GM engineers envisioned it as a test bed for new materials and construction methods that could reduce vehicle mass without compromising safety or durability.

While the Micro CDS-2 never reached production, its influence lived on through GM’s continued pursuit of smaller, more efficient vehicles throughout the following decades. The concept highlighted the company’s willingness to experiment with unconventional technologies and rethink what a commuter car could be. Today, the CDS-2 stands as a fascinating glimpse into GM’s early attempts to blend innovation, efficiency, and performance in a compact form long before lightweight urban cars became mainstream.
