Lancia Delta HF Integrale belongs to a long-produced Lancia Delta family of cars, and it belongs to a first generation of Lancia Delta automobiles, being produces from 1983 to 1994. Produced in over 44.000 units, and since the Integrale was motivated by motor sport, it was engineered more as a race car.
It dominated Rally Championships during the late 1980s and early 1990s. Introduced at the Frankfurt Motor Show, Lancia Delta HF (High Fidelity) was a front-wheel drive, powered by a turbocharged version of the 1.6 litre engine. The system used a Garrett T3 turbocharger with wastegate valve, Marelli Micropex ignition with pre-ignition control, an air-to-air heat exchanger and a blow-trough twin-choke Weber carburetor. With upgrades made to the oil system to withstand the additional stress deriving from turbocharging, ZF 5-speed unit and wide 175/65 Michelin TRX on R 340 alloy wheels, Delta HF Integrale scored 46 Word Rally Championships, while winning the Constructors Championship record six times in a row, from 1987 to 1992.
A special limited edition of the HF, named HF Martini, was launched at the March 1984 Geneva Motor Show. To celebrate the rally victories of the Lancia-Martini Rally 037 it was painted white with a Martini stripe on the side.
Still belonging to the first generations of Lancia Deltas, Integrale Evoluzione was introduced at the end of 1991. The Evoluzione had a wider track front and rear than earlier models of Deltas, while the wings were made in a single pressing, and body side arches were extended and became more rounded. This model retained the four wheel drive layout, while the engine was modified to produce 210 bhp (157 kW) at 5750 rpm. Further external changes included new grilles in the front bumper for improving the air intake for engine compartment cooling, a redesigned bonnet with new lateral air slats for further assistance to under bonnet ventilation, new five-bolt wheels with the same design of the rally cars, and adjustable roof spoiler above the tailgate and a new single exhaust pipe.
Integrale Evoluzione II was presented in June 1993, and it featured updated version of the 2-litre 16-valve turbo engine, as well as Lambda probe and a three-way catalyst. The engine developed 215 PS (158 kW) DIN (against 210 PS on the earlier uncatalysed version) and maximum torque of 32 kgf·m (314 N·m) (formerly 31 kgf·m or 300 N·m). Evoluzione II also received a new body color roof moulding to underline the connection between the roof and the Solar control windows, a 16″ light alloy rims with 205/45 ZR 16 tyres and aluminium fuel cap and air-intake grilles on the front mudguards among other things.
