The build

Lightweight roadster, rotary heart.

A compact 13B trades the original inline-four for a high-revving, twin-rotor powerplant. The imagined build keeps the NA's playful proportions, adds a strengthened driveline, and stays visually close to the car Mazda drew.

Engine: 13B twin-rotor
Target: 280 hp
Curb mass: ≈ 2,250 lb
