6. Mazda RX-01
Mazda’s RX-01 concept, showcased in 1995, hinted at a new era of lightweight, rotary-powered sports cars for all. Powered by a 1.3-liter Wankel rotary engine producing 220 horsepower, it featured a 2+2 seating arrangement and a distinctive front end with a floating bumper/spoiler. Despite its promise, shifting market interests and Mazda’s financial situation led to its cancellation, leaving enthusiasts to imagine a world of accessible, rotary-powered performance.
