It was powered by a 1,585 cc, 105 PS DOHC engine with Marelli Digiplex ignition; lower profile tyres, retuned suspension and disk brakes on all four wheels completed the package.

The cabin features a leather-covered steering wheel and supplementary digital instrumentation with bar indicators; the upholstery material is the usual beige Zegna fabric, and Recaro sport seats covered in the same cloth were optional.

To address some criticisms[23] the car was given less subdued styling features and more generous equipment to differentiate it from the other Deltas: red "HF turbo" scripts on the grille, the side skirts and the rear hatch, a three-spoke sport steering wheel, dual wing mirrors, a two-colour pinstripe along the mid-bodyside character line and Pirelli P6 tyres on 14-inch Cromodora alloy wheels with a new eight-hole design.

A new sporty trim level for the 1.3 was added in May 1990, the Delta Personalizzata, available in red or white with contrasting twin pinstripe and electric blue cloth upholstery; standard equipment comprised body-colour wing mirrors, tachometer, clock and sport steering wheel.

The LX and GT i.e. wore white front turn indicators, a grille with chrome vertical bars, the louvered bonnet from the original HF integrale, and optional 8-spoke diamond-cut alloy wheels from the Dedra.

Its drivetrain was however not related to the more sophisticated one found on the first mass produced four-wheel-drive Lancias, which were shown at the 1986 Turin Motor Show: the Delta HF 4WD and its tamer saloon sibling, the Prisma 4WD.

Initially front biased to maximize traction according to static load distribution, the torque split became increasingly rear-biased with every successive iteration of the Delta HF.

Besides the new bumpers (the front one with integrated fog lights) that would soon be adopted by all Deltas with the 1986 facelift, there were quadruple round headlights—the inner pair smaller in diameter than the outer, red piping around the grille openings, two double pinstripes highlighting the waistline and side crease, and dual exit exhausts.

Inside seats and door panels were upholstered in a combination of grey Alcantara and multicolour "Harlem" wool cloth, supplied by Italian fashion house Missoni.

The instrumentation had yellow scales and hands, a prerogative of all HF models to come; it added two auxiliary gauges to the six already present in the Delta's instrument binnacle, and included a boost pressure gauge, a voltmeter, oil and water thermometers, as well as an oil manometer Some months after the HF 4WD's introduction, at the end of the 1986 season, Group B rallying was terminated after a string of fatal accidents, and Group A took over as the World Rally Championship class.

The match of Lancia's three differential four-wheel-drive system and turbocharged 2.0-litre engine had proven competitive, and through continuous improvements would go on to win six consecutive World Rally Championship titles.

If the Recaro optional seats were ordered, the buyer could choose either full dark grey or green embossed Alcantara upholstery, or extra-cost perforated black leather.

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.

The 1993 Integrale received a cosmetic and functional facelift that included: With ABS, fog lamps and Recaro seats now standard on all markets, the sole optional extra was air conditioning.

Lancia produced several limited and numbered editions models based on the Delta HF Integrale "Evoluzione", each offering unique exterior and interior colours, materials and equipment.

[64] Due to the harsh weather conditions of northern Europe, Saab developed their own heater and made changes to the rust protection, one of a few minor modification from the Lancia design.

[67] The Lancia Hyena was a two-door coupé made in small numbers by Italian coachbuilder Zagato on the basis of the Delta HF integrale "Evoluzione".

Koot thus decided to produce the Hyena from fully finished HF integrales, purchased through the official Dutch Lancia importer LANIM at the time.

Koot's Lusso Service Holland took care of procuring and stripping the donor cars in the Netherlands; they were then sent to Zagato in Milan to have the new body built and for final assembly.

[71] The Orca was a concept car with an aerodynamic five-door fastback body by Italdesign Giugiaro, unveiled at the April 1982 Turin Motor Show; it was based on the Delta platform, with a turbocharged engine and four-wheel-drive which could be disengaged at speed.

[73] The Lancia HIT (standing for "high Italian technology") was a concept car with 2+2 coupé body by Pininfarina unveiled at the April 1988 Turin Motor Show.

Development and tooling work for the Tipo 836 Delta lasted five years[80] and, according to a statement by Fiat CEO Paolo Cantarella, required an investment of 700 billion Lire.

[81] The second generation Delta's world première was held at the March 1993 Geneva Motor Show, alongside that of the final "Evo 2" HF integrale.

The sportier 2.0 HF was also unveiled in Geneva, and went on sale in September; it used a version of the 16-valve 2.0 L equipped with a Garrett T3 turbocharger and an intercooler to produce 186 PS (137 kW; 183 hp).

[84] Mechanical changes from the other Deltas included upsized 205/50 tyres, stiffer suspension, standard 4-way ABS, a "Viscodrive" viscous coupling limited slip differential and, in the HF LS trim, electronically adjustable dampers with two settings.

About a year after the launch, in June 1994, the 1.9 turbo ds turbodiesel variant was added to the range; it was powered by the usual 1,929 cc SOHC unit, pushing out 90 PS (66 kW; 89 hp).

[86] Presented a month later and put on sale in autumn, the Delta 2.0 GT paired the naturally aspirated two-litre engine with the looks of the HF—flared fenders, bumper and spoiler.

At the 1995 Geneva Motor Show the three-door was introduced, christened HPE—a denomination that had previously been used for a shooting brake variant of the Lancia Beta, and standing for "high performance executive".

[94] Visually it continued the monochrome theme of the restyled cars, and it was made more distinctive by bumpers, side skirts, and spoiler of a new design, and 16 inch Speedline Montecarlo alloy wheels with 215/50 tyres; inside the seats were upholstered in black leather with contrasting colour Alcantara centres.

The 2011 facelift of the Delta received trim level changes, a Chrysler-derived family grille, and a 105 PS (77 kW; 104 hp) 1.6-litre Multijet diesel engine with lower fuel consumption and CO2 emissions.
