ISUZU - 117 Coupe (PA90) 1968-1981

Isuzu 117 Coupe

Mass Production 86,192 units 10/1968-5/1981

Giugiaro joined Corrozeria Ghia in December of 1965 and got right to work on two designs that were presented to the public at the Geneva Motor Show three months later. The first one, the G230S-delivered Ghia 450 SS is not included in this publication as Giugiaro's contribution only involved the modification of a few details (grille, light clusters), and not the basic shape.
The Isuzu 117 coupe was to be the Turin designer's first real research project in his new capacity as Styling and Design Center director at Ghia.
The car went into mass production in 1968 and stayed for thirteen years, with almost 100,000 units to its credit. Substituted in 1981 by the Isuzu Piazza, designed by Giugiaro at Italdesign. In Japan the 117 coupe was to become a classic among four seater coupes. So much so that, along the lines of the noblest clubs of European car lovers, when it left production, an Isuzu 117 Fan Club was founded that keeps the historical record and organizes meetings and shows.
Giugiaro had a four-seater coupe theme which led him naturally to the shape layout of the Fiat Dino.
In a more compact form, this design repeats the Dino's belt-line movement and the cut of the trunk lid.
The design of the back side window is original: the window base runs parallel with the belt line rising slightly towards the tail, while the top line is broken just at the start of the C-pillar.
The very classic front end, sports double circular headlights with a horizontal mesh grille.
The trunk lid catches the eye for its very low cut, done to divide the tail section into two symmetrical parts. The rear light clusters are unusual in their upside-down isosceles trapezoidal shape with rounded corners.
The 117 Giugiaro, a super-refined version boasting newly designed interiors, went on the market in 1979. Upholstery and seating expressed shapes, materials and colors that the designer had chosen one year earlier for the Italdesign Megagamma concept car.

The Isuzu 117 Coupe was a mid-sized Gran Turismo type 2-door fastback coupe manufactured by Isuzu Motors Ltd. in Japan from 1968 to 1981. The 117 was a codename for a common development program of Isuzu mid-size cars, involving a coupe, sedan and station wagon. The latter two eventually became the Isuzu Florian, but the coupe kept the original name, and both models shared mechanicals, including the complete FR layout chassis with recirculating ball steering.

The car was styled by the famous Giorgetto Giugiaro, being one of the first Japanese cars designed by an Italian stylist. It was also the first Japanese car with a DOHC engine, and the first with electronic fuel injection. It can also be regarded as the world's first sports car with a diesel engine.

The 117 Coupe was quite an exclusive vehicle during its lifetime, and is a rare collectible now, but thanks to its unusually long lifecycle, Isuzu manufactured as many as 86,192 units. The 117 Coupe was replaced by the Isuzu Piazza in the Isuzu lineup.

[edit]
Early years
The 117 Coupe was debuted as a prototype at the 1966 Geneva Motor Show, and was later shown at the Tokyo Motor Show the same year. In 1968, Isuzu started preliminary small-scale production of 117 Coupes, which were effectively handmade in amounts not exceeding 50 a month. The first engine available was a 1.6 L DOHC I4, and in 1970, an electronic fuel injection unit from Bosch debuted. The model fitted with fuel injection was named the EC (for "electronic control").

The car came with a long list of standard equipment (including leather seats, dashboard trim made of Taiwanese camphor laurel wood, and headrests) and was very expensive for Japanese standards. This concerned also the less luxurious 1800N version added in 1971, powered by a simpler 1.8 L SOHC carbureted engine.

[edit]
Mass production
With the 117 Coupe becoming a very popular and desired model, and the advent of the cooperation with General Motors, Isuzu decided to shift the model to mass production. The 1.8 L engine became standard, with several versions available, with or without fuel injection, DOHC or SOHC.

[edit]
Facelift
In 1977, Isuzu decided to afford the 117 Coupe a facelift, which resulted in replacing the previous front fascia with four round headlights with more modern one with rectangular lights (keeping their number). In an effort to further decrease manufacturing costs, plastic moldings were used in the interior. In 1978, the 2.0 L engine debuted, and in 1979 the XD diesel-powered version was added.

Starting in 1979, a special version called the Giugiaro Edition was available. Production of the 117 Coupe lasted until 1981, when it was replaced by the Piazza, also styled by Giugiaro.

(1) Bosch's electronic fuel injection system, called D-Jetronic, was a speed density system. It adjusted fuel in accordance with the pressure in the intake tube. On the other hand, L-Jetronic was a mass flow system, which directly calculated the air volume taken for fuel adjustment.

(2) The Isuzu 117 Coupe was the first application of D-Jetronic in Japan. This electronically controlled gasoline injection system (ECCG) was installed in the G161WE gasoline engine for commercialization. L-Jetronic was then installed in the G180WE engine to allow it to conform to the emission gas regulations of 1976. Subsequently, the G200WE engine conformed to the emission gas regulations of 1978.

(3) The 117 Coupe engine specifications installed with D- and L-Jetronic ECGI are as follows 

Storage location : ISUZU MOTORS LIMITED (3-25-1 Tono-machi, Kawasaki-ku, Kawasaki-shi 210-8524)

Year manufactured : 1971

Manufacturer : Isuzu Motors Limited

Classification : Literature

Current status : In storage: not open to the public

Company name : Isuzu Motors Limited

Familiar name : ECGI

Installation model : Isuzu 117 Coupe (G161WE engine)

Year of manufacture : 1971

Points of interest, topicality : ・ Predicting progress in car electronics, Isuzu applied such technologies to automobiles, which was a challenging approach at the time. Then ECGI was commercialized for the first time in Japan in the G161EW engine mounted in the Isuzu 117 Coupe.
・It conformed to regulations concerning emission gases, which were becoming an issue in Japan as well as the U.S.

Features : ・ This was a fuel system capable of accurately controlling the air-fuel ratio, which was not possible with a conventional carburetor.
・It enabled emissions to be lowered while improving output and drivability.
