The company produced the MT900R racer and the street-legal MT900S, as well as several unique project vehicles, until its demise in June 2013 when all assets were acquired by Rossion Automotive.

In 1996, an Intruder modified by Lingenfelter Performance Engineering to yield 450 hp won Car and Driver's One Lap of America.

A Photon variant was available which added a Hewland transmission, thinwall subframes, BBS magnesium wheels, titanium springs, and carbon fiber seats and bodywork, reducing the car's mass to 1,980 lb (900 kg).

In 2008, The Mosler Dutch Supercar Challenge, an MT900R only race series ran its inaugural event at the famed Nürburgring F1 track.

Mosler also produced several one-off project vehicles, including a six-wheel custom Jeep that uses many GM components (dubbed the J-10 Sport) and the TwinStar, a Cadillac Eldorado boasting twin Northstar V-8s.
