This is a Maxton Rollerskate and if you’ve never seen one before that may be because just 51 were built back in the early 1990s. All were powered by rotary engines sourced from the first-generation Mazda RX-7, and they had a curb weight of just 1,680 lbs.The Maxton Rollerskate was developed around the idea of taking the compact and lightweight Wankel rotary engine out of the first-generation Mazda RX-7, and installing into a Caterham 7-style roadster. It was a stroke of genius that would create one of the best-handling American sports cars of its era.A new spaceframe chassis made from square tube steel was developed, a lightweight fiberglass body was designed to fit neatly over the top, and the entire drivetrain was sourced from the Mazda RX-7 – including the engine, transmission and live axle rear end.The completed car had unusual styling, including Bug Eye Sprite-style headlights, a side exit exhaust, seating for two, and an exceedingly compact engine bay just big enough to house the tiny RX-7 rotary engine.With a curb weight of only 1,680 lbs (762 kilograms), the Maxton Rollserskate was a lightning quick sports car with a 0-62 mph time of just 5.5 seconds.
