Enthusiastic followers of the Australian GT Championship series may have noticed a new name and striking new shape of Mosler heading grids that were previously the domain of Porsche and Lamborghini

From Unique Cars #300, 2009


The name is Mosler and during the company’s 15 years of existence its cars have surged to the top of high-performance race categories in the US and across the world.

Marque founder Warren Mosler was a successful investment manager who entered the automotive world in 1985. As head of Consulier Engineering, Mosler was more attuned to the company’s core businesses in the medical technology and cleaning products, but drew together a team with the ability to produce a viable and heavily-promoted sports racing car.

Around 100 Consulier GTPs – with a turbocharged 2.2-litre Chrysler engine – were sold before the design was revised to accommodate a 5.7-litre Chev V8. Produced by the newly-formed Mosler Engineering, the renamed Intruder won consecutive 24-hour endurance races at the Nelson Ridges circuit in Ohio. It was replaced in 1997 by the more powerful but less successful Raptor version.

Since 2001, Mosler has produced its MT900 series, with versions for circuit and street use. The model designation incorporated the car’s 900kg target weight (which it failed by 350kg to achieve!) plus the initials of Mosler and the car’s ex-Chevrolet designer Rod Trenne.


Three road-going versions were proposed, with top speeds of 290km/h and 0-161km/h acceleration in 6.5 seconds. The race-prepared MT900R was lightened to slip below 1200kg and powered by a dry-sumped 477kW engine with over 800Nm of torque, driving through a six-speed sequential transmission.

Expanding its motor-sporting activities into Europe brought immediate success for Mosler. On debut in 2003, Moslers scored seven wins to take the British GT Championship and also won the Spa 1000km enduro. Victories in the Spanish GT series and the Silverstone 24 Hour event followed, before the 900R was replaced for 2006 by a version designed to run under European GT3 regulations. However, it was deemed ineligible and most of the cars’ appearances were in British and Belgian events.

Australians first sighted a Mosler during the Bathurst 24 Hour races, where it finished second in 2002 and fifth in the 2003 event. 

Two Mosler GT3s were entered for the 2009 Australian GT Championship; former Porsche driver Craig Baird winning in Adelaide before the cars were forced to carry significant amounts of penalty ballast. In mid-May they were controversially withdrawn from the series.
