The vehicle was available in both RHD (Right Hand Drive) for the UK market, and LHD (Left Hand Drive) for Europe.

The Cosworth engine was based on the Sierra 3 door Cosworth unit.

The Cosworth engine was coloured red to indicate it could be run on Four Star leaded petrol. Fuel injection used Weber/Marelli equipment.

All Cosworth engines are fitted with hardened valve seat inserts and can therefore run continuously on unleaded fuel. With ordinary unleaded petrol it is necessary to retard the ignition by 4 Degrees. A power loss of approximately 10 bhp will be experienced after the ignition is retarded. Retarding the ignition may not be necessary if the engine is always run on Super unleaded fuel.

Front brakes where four pot items on vented disks. Rear braking was also via disks.

Some complaints were heard on the release of this new shape Sapphire Cosworth that the dashboard was particularly bland. For such a high performance engine only minimal instrumentation was fitted.

Front Recaro bucket seats, with adjustable head restraints were used.

Tilt and Slide FFSR (Factory Fitted Sun Roof), Electric windows and mirrors, Central Locking, and Tinted Glass, were all standard equipment.

Available colours where:

• White
• Graphite Grey

The Sierra Sapphire Cosworth had colour coded front spoiler, side skirts and rear boot mounted spoiler.

The Sierra Sapphire 2WD was produced until 1990, when the new 4 wheel drive Sierra Sapphire 4WD Cosworth replaced it.

These types of oil give the necessary engine protection for the high temperatures attained in turbocharged vehicles. The following viscosity synthetic oils are recommended: 5w50, 10w40, 15w50, 10w60.

The Sierra Sapphire Cosworth was based on the Sierra Sapphire of the time. Further details of which can be found in the Ford Sierra 1982 Workshop manual.
