The Lancia Prisma (Tipo 831) is a

saloon version of the first generation Lancia Delta hatchback, and like the Delta it was designed by Giorgetto Giugiaro
. Like the Delta it was also available as a 4x4 integrale version, although with a non-turbocharged engine and an air-locking rear differential.

History

The task of transforming the Delta into a saloon car was given to its original designer Giorgetto Giugiaro, who worked on the car between 1979 and 1980.[3] The two cars share platform (including the 2475 mm wheelbase), drivetrains, doors and windscreen. The Prisma became the most popular Lancia nearly immediately; with a daily production of 250 a cumulative production of 100,000 was reached in 1984.[4]

1982–1986, first series

An early Lancia Prisma

The Prisma was launched in late December 1982

cloth upholstery and some exclusive options, such as air conditioning
.

June 1984 marked the introduction of the Lancia Prisma diesel, the marque's first modern diesel-engined passenger car.

four-cylinder had an iron block, aluminium head and indirect injection; it put out 65 PS. The engine had been developed by Fiat, and was also installed in the Fiat Regata DS—although the Fiat lacked some of Lancia's NVH-improving solutions.[7] The diesel engine was light, only weighing 11 kg (24 lb) more than the 1.6-liter petrol unit.[4] All Diesel Prismas sported a sightly domed hood, needed to clear the taller engine. Some updates were introduced with the diesel, including optional hydraulic power steering
, redesigned seats, new striped cloth upholstery and a four-spoke steering wheel.

About a year later, in May 1985, the Prisma turbo diesel was added to the range.

KKK turbocharger with wastegate valve, an intercooler and an oil cooler; its gearbox was the same ZF 5-speed unit used on the Delta HF turbo.[9]
Power was 80 PS and torque 172 N⋅m (17.5 kg⋅m). The turbo diesel Prisma adopted disk brakes, wheels and tyres from the top-of-the-range 1600 as well as similarly rich equipment, and added standard power steering.

1986–1989, second series

Second series Lancia Prisma

A major mid-cycle refresh débuted at the April 1986

hubcaps. Inside new seats, new instrumentation and air conditioning
system. The 1986 range included seven models, two of them all-new: 1.3, 1.5, 1.5 Automatica, 1.6, 1.6 i.e., 4WD, diesel and turbo ds.[10] 1.3 and 1.5 models had revised intake and exhaust system, fuel cut-off, a new carburettor and breakerless ignition. The diesel versions had also received some minor engine updates, and the turbo diesel had been renamed turbo ds. The new Prisma 1.6 i.e. used a version of the 1585 cc twin-cam engine equipped with
centre of gravity
. The new Prisma 1.6 i.e. could easily reach over 200 km/h.

The other new arrival was the Prisma 4WD, featuring a two-litre fuel injected engine and Lancia's three differential permanent

four wheel drive. Derived from the flagship Thema, the 1995 cc, twin-cam 8-valve engine featured two counter rotating balance shafts
and IAW fuel injection; it developed 115 PS (85 kW) and 163 N⋅m (120 lbf⋅ft). The 4WD package was completed by four disk brakes from the 1.6, power steering and wide, low profile 185/60 tyres on 14-inch 8-spoke alloy wheels. Minor details set the 4WD apart from other Prismas: outside a "4WD" script on the right half of the grille and on the new side skirts, inside it sported the instrument panel from the Delta HF 4WD with six round gauges, yellow scales and hands.

Rear view

In June 1987 the 4WD was updated and rechristened Prisma integrale;[11] it came with standard two-tone paintwork in a choice of three tone on tone combinations, a matching Alcantara interior, and a drop in price from the 4WD — at least in the home market[11][12] where prices were cut by 10 percent.[13]

The last update for the Prisma was the introduction of the eighth model in the range, the upmarket Prisma 1.5 LX, in March 1988.[14] The LX trim added metallic paint, checked cloth interior with beige carpeting and convenience equipment.

The successor of the Prisma, the Lancia Dedra, was unveiled in early 1989, with sales commencing in May; production of the Prisma ended in 1989.

Four-wheel-drive system

Lancia's permanent four-wheel-drive system was based on three differentials. An

open differential, and its planet carrier, through a pair of bevel gears and a three-piece drive shaft, to the rear differential. A Ferguson coupling
controlled the centre differential, preventing excessive relative slippage of the two axles. The epicyclic differential, the Ferguson coupling and the front differential were mounted coaxially in a single transverse unit just behind the engine. In place of the complex Torsen rear differential of the Delta HF 4WD, the Prisma 4WD had a simpler "open" type one, with differential lock—useful at low speeds in low grip conditions—controlled by the driver via a switch on the dashboard. This difference reflected the different goals of the two systems and the destination of the two vehicles: the Delta HF was designed for sport driving, the Prisma for all-conditions safe driving.[3]

Engines

As on the Delta, the

carburettor, a new inlet manifold, exhaust system
and ignition. On Fiat engines Lancia make their own aluminium heads and fuel injection systems, only some parts of Fiat can be used for restoration of Lancia i.e. engines.[citation needed]
