Lancia Delta models

Base Models (Delta 1100, 1300, 1500, 1600)

Stuff will go here...

Delta HF Turbo

In 1982 the sporting side of Lancia began to work on the Delta. The Delta Turbo 4x4 was presented at the Turin motorshow, intended for use in autosports as direct competition to the Audio Quattro. The new Delta had permanent 4-wheel drive and a 130bhp 1600cc turbo-charged engine. In 1983 the car was renamed Lancia Delta HF and was taken in production, but without the 4-wheel drive.

In 1986 the HF Turbo was upgraded to 140bhp, or 133bhp in catalysed form, giving a 0-60mph acceleration time of around eight seconds. Overtaking performance in low gears was excellent, but the car suffered from strong torque-steer when accelerating hard and lacked the low-end torque of its Beta Volumex stablemates. As a consequence of the smaller engine, if the turbo was allowed to slow the Delta would struggle to climb hills that the nominally less powerful HPE Volumex could climb with ease.

Delta S4

In 1985 the 4x4 version was re-introduced. Lancia called it the Delta S4: a Group B rally car. Lancia gave the car both a turbo and a mechanical compressor, for more power at lower revs. The engine now was 1800 cc, had 4 valves per cylinder and performed at a stunning 400 hp, or "only" 250 hp for the detuned engines used in the road cars. With such a powerful engine in a light car the rally S4 could accelerate from standstill to sixty mph in under three seconds, and the road cars in six.

This engine was probably the most complicated ever used in a rally car. The boost provided by a supercharger is roughly proportional

to the engine rotation speed, while the boost provided by the turbo is roughly proportional to the square of the speed. Consequently the supercharger produces far more low-speed boost than the turbo, but the turbo beats it at high speeds. Hence the crankshaft drive wheel for the supercharger was fitted with a centrifugal clutch that disengaged drive at 4000rpm, where the turbo took over. This gave the engine plenty of low-end torque, plus the greatly increased boost of the turbo at high engine speeds. The original single turbo design was later changed for two smaller turbochargers which provided 25psi of boost at higher engine speeds, designed to spool-up at 3500rpm just as the supercharger boost was being bled-off. The inlet ports were in the centre of the head between the camshafts, and the exhaust ports were at the side of the head in the conventional position

The Delta S4 became 1986 world rally champion! Unfortunately, the Group B classed was banned by the FIA after fatal accidents that claimed the lives of both spectators and drivers, including Henri Toivenen who died in Corsica.

Delta HF 4WD

Lancia had a new model: in 1986 the Delta HF 4WD with a 2-litre turbocharged engine was built. The power had increased from 140bhp from the 1.6 2WD HF turbo to 165bhp with power driving all 4 wheels.   The car was upgraded in 1987 and renamed "integrale" - power was up another 20bhp to 185bhp and the wheelarches grew distinctive bulges.

In 1988 the HF Integrale 16V with 200 hp was to be sold to dozens of customers. With a top speed of 220 km/h and accelerating from 0-100 km/h in just under 6 seconds, it was a real GTI-killer! Unfortunately, the way things look right now, this would be the last Delta HF Integrale. In 1995 a two-door sports model of the new Delta, the Delta HPE, was introduced at the Geneva car exhibit, but.... it's only a 2 wheel drive car.

 

Integrale Evoluzione

Integrale fans still have a slight chance of buying a new Delta HF Integrale Edition Finale (you have to go to Japan to get one of the 250 build) or, if you own a Lancia dealership, you might want to get your hands on one of the 250 Dealers Edition models. But that's really the last chance you'll get! (Oh, by the way, both models sell at US $ 80000-100000 in Europe and Japan).

The 1992 Lancia Delta HF Integrale Evoluzione was based on standard 16v Integrale, but with different turbine configuration and base power of 320hp (320hp is for normal customers - factory supported racing teams like Martini Racing have up to 450-480hp)....the dream for every delta owner... (Vlado Mandic)

The Delta Evolution was instantly noticable by its even more flared archers and wider track. It also gained suspension mods, bigger wheels, bigger bonnet bulge and various measures to increase cooling. Inside was much the same but with new Alcantara trimmed Recaros and different clock faces. This car was produced up until about late 93 and I think was the last Delta to win the World Rally Championship.

Evolution II KAT

The next Delta to be launched known as the Evolution II KAT which had a catalyst fitted but the Lancia engineers also gave it another 5 horsepower. It also sported bigger wheels at 17" body coloured rain guttering and I think this is when a power steering fluid cooler was added (serious stuff). The production run of around 600 included several limited editions, of which the 250 mentioned in the article is one. 

Integrale '5' - 5 world championships in a row

White exterior, white wheels, side skirts, martini striping. rear roof spoiler (black), rear hatch has martini striping running along back between badges (one says integrale, the other 'world rally champions'

Recaro competition high-back seats, alcantara with red piping. Similar treatment to rear seats and door panels. Red seatbelts!

Integrale 'Club Italia'

Club Italia is an exclusive Italian club, so Lancia produced a limited edition of 15 for the Club. Probably the rarest integrale.

Black, only 15 made. Cam cover yellow with blue stripe - just like the Fulvia HF. Red leather high back seats, drilled alloy pedals, alloy exposed fuel filler, different gear lever with small black ball on alloy stalk, and the little cubby beside the radio has a carbon fibre insert in with push button starter.

Integrale 'verde york'

Special york green bodywork, numbered plaque on dash, champagne highback recaros, air conditioning.

integrale '6' - 6 world championships in a row

White bodywork, 'world rally champion' decals on bottom of front doors, HF decals on the rear pillar, turquoise Alcanta recaro highbacks with red piping, red seatbelts, competition style gearlever knob, red cylinder head cover.

integrale 'gialla'

Yellow bodywork, black alcantara highbacks with yellow piping, larger inner headlamps like early integrales but other way round.

Zagato have built their own Delta derivative by fitting the Integrale's mechanical components to their own two-door coupe bodywork. The body and interior make extensive use of lightweight materials such as kevlar, significantly reducing the car's weight over that of the Integrale. Consequently acceleration is increased, but the top speed is limited by the Integrale's gear ratios. Only 25 cars were produced, each at a price of around £75,000.
