Model history and curiosity

The Ford Sierra RS Cosworth is a sports car, produced by the American car manufacturer Ford from 1986 to 1992, as a high-performance version of the Ford Sierra, in order to be homologated and compete in the Group A category in the rally and touring championships.

In April 1983 the team led by Turner decided to use the Sierra as the basis for the future car to be homologated in Group A.

Many of the differences and suspension improvements between the standard Sierra and the Cosworth were developed using experience learned from racing Jack Roush's turbocharged Merkur of the Sierra Cosworth was developed from the experience gained with the XR4Ti. The suspension and aerodynamic engineering was done based on the cars Roush used in IMSA. Some components of the XR4Ti were reused on the Cosworth, such as the dashboard and instrument panel or the chassis stiffening plates.

Lothar Pinske, responsible for the car's bodywork, mounted a wing on the tailgate to make the car more stable at high speeds, as the body of the standard Sierra generated some aerodynamic lift even at relatively moderate speeds.

After numerous tests and trials in the wind tunnel and on the Nardò circuit in Italy, a prototype was presented to the project management. This was based on an XR4i body with temporary fiberglass and aluminum modifications. Aesthetically the biggest differences compared to the other Sierras were the rear wing which had been mounted to increase stability at high speeds and the air intake between the headlights, which was necessary to cool the intercooler and the wheel arches which were used to house the larger wheels with 10-inch channel of the competition version.

Cosworth YBD engine from a Sierra RS500; note the second set of 4 additional injectors
Furthermore, Ford took some measures to reduce the price of the car. For example, the car was offered with only three colors (black, white and grey) and a single interior colour, grey. There were only three options: central locking, sunroof and electric windows.

The Ford Sierra RS Cosworth was first presented to the public at the Geneva Motor Show in March 1985. It was launched in July 1986 and 5545 were produced in total, of which 500 were sent to Tickford to be converted into the RS500 version.

Under the front bonnet, the car was powered by the Cosworth YBD, a 1993 cm³ twin cam 4-cylinder engine with 16 valves which was powered by indirect multipoint electronic injection with 4 Weber injectors and also electronic ignition by Marelli, with Garrett T3 turbine, which delivered 204 horsepower. The car reached a top speed of around 149 mph and sprinted from 0-60 mph in 6.5 seconds. Aerodynamically, it had a drag coefficient of 0.345 and the rear spoiler generated a maximum downforce of 20 kgf at 150 mph. Mechanically it was equipped with a braking system with four self-ventilating discs equipped with ABS, with the front brakes having a disc with a diameter of 28.3 cm which was bitten by 4-piston calipers, while at the rear there were 27.3 discs cm with double pumping caliper. The Cosworth wore 205/50 VRx15 tyres, on 15"x7" BBS alloy wheels. The gearbox was a 5-speed gearbox, with a limited-slip viscous coupling rear differential.

The second generation Sierra Cosworth was based on the contemporary four-door Sapphire and was assembled in Genk, Belgium, with the Cosworth YBD engine being built in the UK. The suspension was essentially the same, but with some small changes to the geometry to adapt to a less aggressive driving style and to favor rideability more than handling. Approximately 13,140 examples were produced during 1988-1989 and were the most numerous of all Sierra Cosworth models.

Rear Sapphire RS Cosworth
In the UK 1988-1989 Sierra Sapphire RS Cosworths are marked with small 'Sapphire' badges on the rear door window mouldings.

The Sapphire Cosworth, having a smaller rear wing, recorded a drag coefficient of 0.33, thus allowing it to record slightly better speed performance (maximum speed above 150 mph and 0-60 mph in 6.1 seconds) compared to to the original Cosworth.

 

In January 1990 the third generation of the Sierra RS Cosworth was launched, this time featuring four-wheel drive as standard. Already in 1987 Mike Moreton and Ford Motorsport had begun developing a four-wheel drive Sierra RS Cosworth which the company planned to make Ford more competitive in the World Rally Championship.

The 4x4 version was launched to coincide with the restyling of the regular Sierra in 1990.

THE 4X4 COSWORTH:
The 4x4 was distinguished aesthetically by the presence of slits on the bonnet, as on the original three-door coupé and which had been removed on the Sapphire 2WD. The engine was further improved and was signed YBG with the catalytic converter and YBJ for those without; the power reached 220 HP delivered at 6250 rpm and the torque developed was 29.5 kg at 3500 rpm. The first difference between the old YBD engine was in the valve cover which was now green, compared to the red of the 2WD. The traction was all-wheel drive equipped with a new Ferguson MT75 differential and gearbox, with torque distribution 34% to the front axle and 66% to the rear axle.[9] 0 to 100 was covered in 5.9 seconds, while the maximum speed was 242 km/h. All these changes increased the mass by 100 kg compared to the 2WD.

Production continued until the end of 1992, when the Sierra was replaced by the Mondeo ST200. However, the direct heir to the Sierra RS Cosworth was the Escort RS Cosworth, which was homologated for use in Group A in December 1992, just when the Sierra RS Cosworth was withdrawn from production.
