Introduced in 1990 and made until 1992 was the performance version the 3rd generation Ford Fiesta called the RS Turbo. Sitting lightly on the road at just 920 kg, the Fiesta RS Turbo was lively little hot hatch. The 1597cc 4-cylinder engine featured an 8:1 compression ratio and was supplied with 8 psi of boost from a single Garrett T2 turbocharger. The T2 turbo was chosen over the T3 used in the Escort RS Turbo due to space constraints of the mounting position between the engine and radiator.
The RS Turbo was based off the Fiesta XR2i which was released just a year prior and was visually very similar. key differences included larger 14" alloy wheels on the RS Turbo with colour-coded rear spoiler and door pillars, opening rear quarter windows, green tinted glass and RS bonnet louvres.
