Lancia Delta I Integrale 8v
The Lancia Delta was a successful car sold by Lancia from 1979 to 1994 and was designed by Giorgetto Giugiaro. Taking the all-conquering Delta HF 4WD that decimated it’s rivals on tarmac, snow, ice and loose surfaces throughout the 1987 season, Lancia designed the HF Integrale 8v to incorporate all the advanced technical features of the rally car enhanced by the lessons learned in the world’s toughest motor sport arena. The result is a stylish, luxurious yet utterly practical five door hatchback with impeccable road manners, but capable of a blistering 0-62 mph acceleration in just 6.6 seconds and a maximum speed of 133 mph.
At the heart of the 8 valve HF Integrale is a two litre 4 cylinder fuel injected twin cam engine, fitted with contra-rotating balancing shafts. This version, of what is surely one of the world’s most competition proven power units, incorporated the following improvements over the HF 4WD: 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 air flow and bigger inter-cooler to aid volumetric efficiency, together with revised settings for the electronic injection/ignition control unit and a knock sensor, boost power output to 185 bhp (DIN) at 5,300 rpm and maximum torque of 3l mkg (224.13 lb ft) at 3500 rpm.
The Delta boasts one of the worlds most advanced transmission systems incorporating permanent 4wheel drive, a front transversely mounted engine and 5 speed gearbox. An epicyclic centre differential normally splits the torque 56 per cent to the front axle, 44 per cent to the rear. However a noiseless, fully automatic Ferguson viscous coupling balances the torque split to give the optimal division 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. By using the interaction between a worm screw and helical gear (movement is transmitted from screw to gear only ) the Torsen system ensures that the wheel with less weight or grip receives less torque and therefore maintains traction. A free floating front differential completes the system to ensure maximum traction even at speed on adverse road surfaces. A shorter final drive ratio (3.111 instead of 2.944 on the HF 4WD) is used to match the larger 6.5 X 15 wheels to give 24 mph/1000 rpm in fifth gear. Both braking and suspension were uprated to match the HF Integrale’s increased performance. The ventilated front discs were increased in diameter to 284 mm, improved friction coefficient pads were fitted to the rear brakes. A larger brake master cylinder and servo lessened pedal effort for quicker response and reduced the risk of overheating in even the most demanding situations. The all round independent suspension features new front springs, dampers and front struts.
In line with the mechanical improvements and higher performance, Lancia gave the HF Integrale a new, more purposeful look while retaining all the practical advantages of the five door body shell. Immediately noticeable are the rounded, bulged wheel arches housing 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 to assist engine cooling, and houses rectangular auxiliary driving lights, that compliment the twin circular headlights. The side skirts are faired into the wheel arches at front and rear and carry “Delta HF Integrale” badges to compliment those on grille and rear hatch. The twin rear view mirrors are finished in body colour.
