Lancia Delta HF Integrale: red version
The Lancia Delta HF integrale incorporated some of the features of the Delta HF 4WD into a road car. The engine was an eight-valve 2.0 L fuel injected four-cylinder, with balancing shafts. The HF version featured new valves, valve seats and water pump, larger water and oil radiators, more powerful cooling fan and bigger air cleaner. A larger capacity Garrett T3 turbocharger with improved airflow and bigger intercooler, revised settings for the electronic injection-ignition control unit and a knock sensor, boost power output to 185 PS (136 kW; 182 hp) at 5,300 rpm and maximum torque of 31 m·kgf (304 N·m, 224 lbf·ft) at 3,500 rpm.
The HF integrale had permanent four-wheel drive, a front transversely mounted engine and five-speed gearbox. An epicyclic centre differential normally splits the torque 56 per cent to the front axle, 44 per cent to the rear. A Ferguson viscous coupling balanced the torque split between front and rear axles depending on road conditions and tyre grip. The Torsen rear differential further divides the torque delivered to each rear wheel according to grip available. A shorter final drive ratio (3.111 instead of 2.944 on the HF 4WD) matched the larger 6.5×15 wheels to give 24 mph/1,000 rpm (39 km/h per 1,000 rpm) in fifth gear.
Braking and suspension were uprated to 284 mm (11.2 in) ventilated front discs, a larger brake master cylinder and servo, as well as revised front springs, dampers, and front struts.
The HF integrale was facelifted with bulged wheel arches for the wider section 195/55 VR tyres on 15-inch 6J alloy wheels. A new bonnet incorporated air louvres while the restyled bumpers wrapped around to meet the wheel arches at front and rear. The front bumper, now wider, incorporates air intakes and for the rectangular auxiliary driving lights. The side skirts are faired into the wheel arches at front and rear and the twin rear view mirrors are finished in body colour. There were only 50 RHD factory built cars, none of which were officially imported to the UK.
