Origins
Financier Warren Mosler believed racing rewarded weight and downforce, and the MT900 of 2001 was the belief made carbon: a 1,100-kilogram mid-engined coupé designed by Rod Trenne around Corvette V8 power, with aerodynamics that generated racing-car grip from road-car parts. Competition versions promptly embarrassed established GT machinery — winning so comprehensively in various series that organisers responded with weight penalties, rule rewrites and outright exclusions, a pattern Mosler wore as vindication. Road versions, including the Photon lightweight, were built in tiny numbers in Florida and Britain through the 2000s. The MT900's legacy is its argument: that lap time is physics, purchasable without heritage — an argument the sanctioning bodies conceded every time they changed the rules to contain it.
