In April 1985 the hot hatch version of the first series Uno – the Uno Turbo i.e. – was launched as a three-door only derivative. It competed with the likes of the Ford Fiesta XR2, MG Metro Turbo and Peugeot 205 GTI.

Despite marketing claims that the Uno Turbo i.e. was fitted with an engine "specifically developed for turbocharging" the Turbo i.e. model actually used a Ritmo/Strada-derived 1.3 128-series engine with Bosch multi-point fuel injection, Magneti Marelli electronic ignition and a water-cooled IHI turbocharger with an intercooler to reduce intake air temperatures.

The resultant power plant was highly regarded and considered as more technologically advanced than many of its contemporaries. Engine capacity was initially stated as 1299 cc but this was revised early on in production to 1301 cc. This change was a result of Italy's highway system allowing a higher speed limit to cars of more than 1300 cc.

In both forms the engine offered 106 PS (78 kW; 105 hp) but owners report that the 1301 cc version was notably more responsive and had greater torque than the earlier 1299 cc unit. Cars built from 1985 to late 1987 were fitted with a Ritmo/Strada-derived five-speed gearbox.

This was then replaced by a newly developed 'C510' five-speed gearbox, often referred to by owners as the 'Tipo style' gearbox, featuring a more durable differential and improved gearchange linkage. Ratios were unchanged between the two units.

The Turbo i.e. offered significant performance improvement over standard Uno models and was capable of reaching 200 km/h (124 mph), thanks in part to the car's low 845 kg (1,863 lb) weight. Reliability was improved due to the reduction in maximum turbo boost pressure for mass-production from 1.0 to 0.6 bar but conversely, it allowed tuners to modify the engine relatively easily to run 1.0 bar boost pressure for even greater performance without significantly compromising reliability.
