Exomotive

Exomotive is an American automotive manufacturer based in Atlanta, Georgia, best known for creating the Exocet—an exoskeletal, lightweight component sports car built around Mazda Miata running gear.

Key Aspects of Exomotive and the Exocet

• The Concept: Following Colin Chapman’s minimalist mantra of "adding lightness," the Exocet strips away the heavy factory body of a donor vehicle and places a rigid, tubular steel space frame over the mechanical components. The result is an ultra-lightweight track and street toy (typically weighing between 1,400 and 1,600 lbs) with an exceptional power-to-weight ratio.
• The Donor Platform: The car is engineered to utilize 1990–2005 Mazda Miatas (NA and NB generations) as donors, harvesting essential components like the suspension, steering, brakes, wiring, and drivetrain.
• Powertrain Versatility: While it easily accepts standard Mazda 1.6L and 1.8L inline-fours (naturally aspirated or turbocharged), the open architecture of the chassis accommodates major engine swaps. Enthusiasts and builders frequently drop in Honda K-series engines, GM Ecotec powerplants, GM LFX V6s, or even monster GM LS V8s pushing upwards of 500+ horsepower into the lightweight frame.
• Lineup: Exomotive offers multiple variations of the platform, including Sport and Race versions tailored for high-performance street use or dedicated road-course duty, alongside Off-Road configurations designed for rugged utility.
• Build Accessibility: The kit is designed with home garage builders in mind, utilizing a comprehensive bolt-together tube chassis approach that typically requires standard hand tools, basic mechanical knowledge, and roughly 100 hours of assembly time.
