The Ford Mustang GTX was an American GT race car constructed to compete in the GTX category of the IMSA GT Championship series by Ford. Originally based on the second generation Ford Mustang (known as the Mustang II), and later the third generation Ford Mustang (commonly referred to as the "Fox-Body Mustang") road car, built between 1979 and 1983. [2] [3] It was initially powered a 1.7-liter twin-turbo four-cylinder engine, supplied by Zakspeed, and producing around 600 hp (450 kW). This was later changed in 1982, to an enlarged 2.1-liter turbocharged variant of the Ford-Cosworth BDA straight-four engine, capable of producing around 675 hp (503 kW; 684 PS). [4] The car was very light, weighing only around 1,760 lb (800 kg). [5]

The car competed in the then new IMSA GTP category in 1982.

The third-generation Mustang was manufactured and marketed by Ford from 1979–1993, using the company's Fox platform and colloquially called the Fox body Mustang. During its third generation, the Mustang evolved through several sub-models, trim levels, and drivetrain combinations during its production and seemed destined for replacement with a front-wheel drive Mazda platform. Company executives were swayed by consumer opinion and the rear-wheel drive Mustang stayed in production, while the front-wheel drive version was renamed the Ford Probe. Production ended with the introduction of the fourth-generation Mustang (SN-95) for model year 1994.

<span class="mw-page-title-main">Ford Thunderbird (ninth generation)</span> Ninth generation of the Ford Thunderbird

The ninth generation of the Ford Thunderbird is a personal luxury coupe that was manufactured and marketed by Ford for the 1983 to 1988 model years. In response to the sales downturn of the 1980–1982 Thunderbird, the model line underwent one of its most substantial redesigns for the 1983 model year. While the Thunderbird remained as a personal luxury coupe, Ford transitioned its role, emphasizing performance and handling over outright luxury and comfort content. As a design leader for Ford, the ninth-generation Thunderbird marked the introduction of highly aerodynamic body design for Ford vehicles in North America, followed by the 1984 Ford Mustang SVO and Ford Tempo and the 1986 Ford Aerostar and Ford Taurus.

The Ford Mustang GTP was an American race car constructed to compete in the IMSA GTP series by Ford in 1983, based on the "Fox-Body" generation of the Ford Mustang road car. In 1983 the engine was a 1.7 liter twin turbo supplied by Zakspeed. In 1984 it used a destroked 2.1-litre 16 valve turbocharged variant of the 2.3 litre Ford Lima engine, capable of producing around 600 hp. The 2.1 litre engine is often misidentified as more common 2.1 litre variant of the BDA. Contrary to convention for an IMSA GTP car, the engine was fitted in the front of the car. Zakspeed would replace the car with the Ford Mustang Probe for 1985, while Roush Performance would build the no more successful V8-powered Ford Mustang Maxum GTP in 1987.

The Ford Probe GTP, also sometimes called the Ford Mustang Probe GTP, was an IMSA GTP sports racing car, designed, developed and built by German constructor Zakspeed, and used by the Zakspeed Racing team in the 1985 IMSA GT Championship. It was based on the standard road-going Ford Probe, and was the successor to the Ford Mustang GTP race car. Unlike the road car, using a conventional front-engined designed, the prototype race car used a mid-engined design. It was powered by a 2.1 L (130 cu in) engine that was based on the Zakspeed 1500, as used in Zakspeed's Formula 1 cars. The 2.1 litre engine that was used in the Ford Probe GTP is often confused with the Ford Lima based engine that was used in the Ford Mustang GTP and the 2.1 litre variants of the Cosworth BDA engine. In Endurance racing trim it produced 600 hp (450 kW), which was plenty powerful enough for the lightweight 1,770 lb (800 kg) vehicle. This drove the rear wheels through a five-speed Hewland VG5 manual transmission. Klaus Ludwig, Doc Bundy, Lyn St. James, Scott Pruett, Pete Halsmer, Arie Luyendyk, Tom Gloy, and Chip Robinson all drove the car. Highlights for the car included two second-place podium finishes at Watkins Glen and Sears Point in 1985, and an outright win for Klaus Ludwig at Laguna Seca in 1986.
