Mosler MT900

The Mosler MT900 is a sports car built by the now-defunct American automotive manufacturer Mosler Automotive from 2001 to 2011.

Three submodels were produced. The MT900R was a racing version of the MT900. The basic car was updated as the MT900S for 2005, with the MT900S Photon being an optional performance package. The original MT900 was introduced in 2001 and the MT900S finished production in May 2011. Components for 25 MTs were produced as of January 2005, though only about 35 road cars and 50 racing versions have officially been completed (c.20 of which are MT900S). The MT900 was the replacement for the Mosler Raptor.

The MT900 was designed by Rod Trenne, who previously worked on the Corvette C5. The initials were for Mosler, Trenne, and the car's 900 kg (1,984 lb) target weight.

The MT900 used a carbon-fiber chassis with a LS6 V8 engine mounted amidships, powering the rear wheels. Power output is 350 hp (261 kW), with 350 lb⋅ft (475 N⋅m) torque. A ZF transaxle, designed for Porsche, was mounted upside down to allow the engine to sit in front of the rear axle.

The original MT900 weighed 1,175 kg (2,590 lb), much more than the target weight, but could still accelerate to 60 mph (97 km/h) in 3.5 seconds according to Car and Driver. The MT900 they tested could also do a 12.0 second quarter mile at 118 mph (190 km/h), and they recorded a top speed of 150 mph (241 km/h),^{[citation needed]} limited by the redline. The MT900 pulled 1.02 g on the skidpad. The U.S. Environmental Protection Agency (EPA) estimated 19 mpg_‑US (12 L/100 km; 23 mpg_‑imp) and 28 mpg_‑US (8.4 L/100 km; 34 mpg_‑imp) in city and highway driving, respectively.^{[citation needed]}

The exterior was designed for aerodynamics, with a 0.25 coefficient of drag. List price was US$164,000. Only a single prototype was produced.^{[citation needed]}

Introduced at the same time as the basic MT900 was the race-ready MT900R. It was designed for use in various international motorsports series for an estimated price of $119,000. The MT900R made its competition debut at the 2001 24 Hours of Daytona, and would be campaigned by a factory Mosler team for the full season of the Grand American Road Racing Championship. The entry finished the year ninth in their class championship.

For 2002, the French Perspective Racing team would become the full-season entry in Grand American and saw an improvement in performance. At Daytona the MT900R finished 13th overall and fifth in their class before winning at the next round at Homestead-Miami Speedway, helping the team to third in the championship. Rollcentre Racing and Balfe Motorsport (with aid from Rollcentre) would bring the Moslers to Europe in 2003, starting the British GT Championship year strong with three straight one-two finishes, before finishing the year with four more victories. The Rollcentre squad edged out Balfe for the championship that year. In Grand American, the Moslers were moved to the faster GTS class, but Perspective Racing improved on the previous year's Daytona effort with a ninth-place finish and the class victory. Mosler Automotive would take one more victory that season.
