3. Mazda RX-8
The Mazda RX-8 was a bold experiment, boasting a high-revving rotary engine and an unconventional four-door coupe layout.
Its balanced chassis and responsive handling rivaled the likes of the Nissan 350Z, yet mainstream car buyers never fully embraced its quirks.
Despite strong performance and positive press—see the Motor Trend review—rotary engine reliability concerns and niche appeal limited its success.
Today, the RX-8 remains a fascinating, underappreciated chapter in Mazda’s performance legacy.
