Three-quarters front view of a Lancia Delta HF Turbo, on display at the 2023 British Motor Show
The first true performance-oriented Delta was the Delta HF, which was introduced in July 1983 and went on sale in September after a first appearance at the Frankfurt Motor Show. The HF acronym—last used on the Stratos—stands for "high fidelity", and had been applied to sports and racing variants of Lancia cars since 1966. It is front-wheel drive and powered by a turbocharged version of the engine from the Delta GT; the system consists of a Garrett TBO-225 turbocharger with wastegate valve, an air-to-air heat exchanger, a blow-through twin-choke Weber carburetor and Marelli Microplex ignition with pre-ignition control. To withstand the additional stress deriving from turbocharging, upgrades were made to the oil system, with increased capacity and an oil cooler, and to the cylinder heads with sodium-filled valves. The gearbox is a ZF five-speed unit. Dampers, springs and steering were retuned, and the tyres are wide 175/65 Michelin TRX on R 340 alloy wheels. The exterior of the HF is relatively understated: changes were limited to silver "HF" badging on the grille, a deeper chin spoiler, black trim as on the GT, black roof drip rail mouldings, black side skirts with small silver "turbo" badges in front of the rear wheels, the 1982 roof spoiler painted in black, air intake cowls on the bonnet grilles, bronze-tinted athermic glass and eight-spoke alloy wheels. 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. About ten-thousand Delta HFs were made, in a two-year production period. 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 sides below the door handles, and carried Martini-coloured
