The Messerschmitt KR200, or "Kabinenroller," is a three-wheeled microcar produced in Germany from 1955 to 1964. Designed by aircraft engineer Fritz Fend, its fuselage-style body and bubble canopy reflect its aviation heritage. It features tandem seating and an aircraft-inspired steering yoke instead of a traditional wheel. Powered by a 191cc two-stroke engine, it reaches 65 mph with impressive fuel efficiency. A unique mechanical quirk allows it to reverse by restarting the engine backward, providing four reverse gears. This iconic "bubble car" gained fame through celebrity fans like Elvis Presley and remains a celebrated piece of automotive history.

The 1958 Firebird III was General Motors' most advanced concept car, blending jet-fighter styling with Space Age technology. Designed by Harley Earl, it featured a fiberglass body with seven fins and a double-bubble canopy. Inside, a joystick replaced the steering wheel and pedals to control steering, acceleration, and braking. It utilized a dual-engine system: a rear gas turbine for propulsion and a front gasoline engine for accessories. This "laboratory on wheels" introduced innovations like cruise control and anti-lock brakes, while its bold aesthetics directly influenced future Cadillac production designs.

The Mercedes-Benz C111 is a tawny spaceship, a wedge-shaped dream carved from fiberglass and ambition. With its shimmering gull-wing doors and slippery silhouette, it exists in the liquidity of time—a 1970s vision of a future that never quite arrived. Originally a laboratory for the high-revving Wankel engine, this orange mirage transitioned from rotary whispers to record-breaking diesel roars at the Nardò Ring. It remains an evocative masterpiece of "what could have been," blending advanced aerodynamics with a luxurious soul, forever rocketing between nostalgia and the avant-garde.
