View of a Yellow, 1992 Lancia Delta HF Integrale Evo 1, on display at the 2021 London Classic Car Show
At the September 1991 Frankfurt Motor Show Lancia introduced an heavily revised Delta HF, once again named "Delta HF integrale"—but which became better known as the "HF integrale Evoluzione" or simply "HF integrale Evo". Evoluzione cars were built from October 1991 through 1992. At the end of the victorious 1991 World Rally Championship season, where the HF integrale 16v had won both the drivers' and manufacturers' championships, Lancia officially retired from rallying. Despite this, racing development of the HF integrale continued, and factory-developed HF integrale Evos were fielded by independent Martini Racing-sponsored Jolly Club for the 1992 season. Thanks to the two factory-backed privateer teams, Lancia won its sixth and final consecutive Constructor's World Rally Championship. These were to be the final homologation cars; the catalytic 1993 Evoluzione 2 was not developed by the factory into a rally car. The Evoluzione's engine was the same turbocharged 16-valve two-litre used on the previous model, but power had increased to 210 PS (154 kW; 207 hp) at 5,750 rpm, chiefly thanks to a new single outlet 60 mm diameter exhaust system.[37] Maximum torque was unchanged at 31 kgf⋅m (300 N⋅m; 220 lbf⋅ft), but was now reached at a higher, 3,500 rpm. An eight-valve "kat" catalytic converter-equipped variant, with an unchanged 177 PS output, continued to be produced for countries where such equipment was mandatory. Mechanical changes included a strengthened steering rack and a power steering oil radiator. The suspension was reworked and strengthened, using box section track control arms. Front strut towers were raised, which necessitated an aluminium strut brace. The braking system featured larger diameter discs and vacuum servo, and fixed two-piston Brembo calipers at the front. No changes were made to the four-wheel-drive system. Front and rear tracks were wider than on earlier Deltas, respectively 54 and 60 mm ( and in).
