The Dodge Omni and Plymouth Horizon were subcompact cars produced by Chrysler from December 1977 to 1990.[1] The Omni and Horizon were badge engineered variants of the Simca Horizon, and were the first of many front-wheel drive Chrysler products to follow, including the Dodge Aries/Plymouth Reliant and the Dodge Caravan/Plymouth Voyager/Chrysler Town and Country.

History[edit]

Main article: Simca Horizon

The Dodge Omni and the Plymouth Horizon were front-wheel drive, five-door hatchbacks, introduced by the Dodge and Plymouth divisions of Chrysler in North America in 1977 (for the 1978 model year). The Omni and Horizon were the first front-wheel drive cars produced by Chrysler, the first front-wheel drive, transverse engine, production cars in the North American market,[citation needed] and among the first American front-wheel drive cars to sell in large numbers. (Previous front-wheel drive American cars such as the Cord 810, Cadillac Eldorado, and Oldsmobile Toronado were low-volume luxury cars.)

Talbot Horizon

The Omni and Horizon were loosely based on the Horizon, a subcompact car designed by Simca, the French division of Chrysler Europe, and built on the then-new L platform. It survived, in various guises, in Europe until 1987.

Born largely out of the need to replace the aging Simca 1100, the Horizon was essentially a shortened version of the larger Alpine, giving the vehicle an unusually wide track for its length. The Horizon, or Project C2 as it was known inside Simca during development, was intended to be a "world car" (designed for consumers on both sides of the Atlantic), but, in execution, the European and North American versions of the vehicle actually turned out to have very little in common. When Chrysler exited the European car market (and sold assets to Peugeot, which subsequently sold the same car in Europe as the Talbot Horizon) in 1978, Chrysler retained the North American rights to the car, and began production at Belvidere.

Plymouth Horizon

Chrysler had previously avoided building a subcompact car, preferring to use branded imports like the Mitsubishi-made Dodge Colt instead.

Presented as a significant domestic development, the models were initially priced starting at US$2,500. The Dodge Omni was Motor Trend magazine's Car of the Year for 1978, and the related Talbot Horizon was voted European Car of the Year in 1979.

The Omni and Horizon appeared at a critical time for Chrysler, when Chrysler was in bankruptcy protection and sought government support to survive. In 1978, Chrysler had beaten both Ford and GM to the market with a domestically-produced front-wheel drive car to challenge the VW Rabbit.[2] The new small cars began to sell well, and helped persuade government legislature that Chrysler was a company worth saving.

The Omni and Horizon had few interchangeable parts with their European siblings. Aside from the heavier-looking American body panels and bumpers, the OHV Simca engines were replaced with a 1.7 L OHC engine sourced from Volkswagen, while MacPherson strut front suspension took the place of the torsion bar arrangement found in the European Horizon. The Volkswagen engine used an enlarged Chrysler-designed cylinder head and intake manifold and produced 75 hp (56 kW) and 90 lb·ft (120 N·m).

The HVAC controls were mounted to the left of the steering wheel rather than in the center stack like in most vehicles, meaning only the driver could adjust the interior temperature. Other Chrysler Corporation products (including the Dodge Charger and Chrysler Cordoba), as well as vehicles from other manufacturers came with instrument panels that placed the HVAC controls in this general location during the 1970s.

Shortly after their introduction Consumer Reports tested the models and reported that it lost control in hard maneuvering. The allegation received extensive mainstream coverage, including a piece in Time Magazine.[3] Other auto magazines reported no problems and said the test did not approximate real-world driving conditions. Chrysler made modifications that included a steering damper and a lighter weight steering wheel.

Chrysler's 2.2 L K-car engine appeared in 1981 as an upmarket option to the Volkswagen engine. It produced 84 hp (63 kW) at first, rising to 93 hp (69 kW) and finally 96 hp (72 kW) by the end of production. The Volkswagen 1.7 was replaced by a Simca 1.6 L inline-four unit in 1983. This engine produced 62 hp (46 kW) and 86 lb·ft (117 N·m), and was only available with a manual transmission. The Omni/Horizon received a facelift in September 1983.[1]

In 1985, Chrysler entered an agreement with American Motors Corporation (AMC) to produce Chrysler M platform rear-drive, as well as Omnis and Horizons, in AMC's Kenosha, Wisconsin plant. The 2.2 L Chrysler inline-four cylinder was the only available engine from 1987 onwards.

Chrysler invested in a number of significant changes that ended up being used for only one year; the cars gained larger exterior rear-view mirrors (borrowed from the departed M-body sedans), a driver's side air bag and a mildly redesigned instrument panel, complete with HVAC controls finally moved to the center.

The Omni and the Horizon ended production in 1990, and were replaced by the Dodge Shadow/Plymouth Sundance, which were both introduced in 1987. It outlived the European version by three years; Peugeot had bought Chrysler's European division in 1978 and re-badged the Horizon (along with the rest of the British Chrysler and French Simca range) as Talbots, with production lasting until 1987.[4]

As production was being wound up all tooling needed to produce the vehicle was sold to the Tata Group in India, and the car was produced there for several more years.

Variants[edit]

Several variants of the platform appeared later, including a 3-door hatchback known as the Dodge 024/Plymouth TC3, and briefly a small car-like truck under the Dodge Rampage/Plymouth Scamp name.

The 024 and TC3 were marketed as sporty cars, although the 94 hp (70 kW) four-cylinder engine was not powerful. The TC3 was renamed the Plymouth Turismo, and the 024 the Dodge Charger in 1983. The last 1,000 Dodge Chargers were modified by Carroll Shelby into Shelby GLHSs.

GLH[edit]

1984-1985 Dodge Omni GLH

The ultimate Dodge Omni was the modified Omni GLH. The original name, "Coyote", was rejected, and Carroll Shelby's choice, the initials GLH, which stood for "Goes Like Hell", were taken instead.[5] 1984 was the first year of the GLH, which carried over most of the modifications that had been made the previous year to the Shelby Charger. 1985 was the debut of the GLH-T model with the Turbo I (K) engine option. This engine, at low boost (7.2 PSi) coupled with the car's very low weight (as low as 2,200 lb (1,000 kg)), earned this car its name. The car carried over into 1986 unchanged aside from the addition of a hatch-mounted third tail light, and production was then stopped.

1986 Shelby GLHS

The final 500 GLH-T cars (all black) were sold to Shelby, who used them as the basis for the 1986 Shelby GLHS ("Goes Like Hell S'More"). These cars were modified by Carroll Shelby in California and sold as Shelbys. With 175 horsepower (130 kW) and 175 lb·ft (237 N·m) of torque, the Shelby GLHS was a modified 2.2 with a Turbo 2 setup which included a two-piece blow through intake (the GLH-T was a draw through turbo design) shelby ECU, boost raised to a conservative 12psi, T2 turbocharger compressor cover, and a front-mounted intercooler. The short block stayed the same between the GLH-T and GLHS. Further modifications included 205/50R15 Eagle GT Gatorback tires mounted on Shelby Centurian wheels, Koni adjustable struts and shocks, and stiffer springs. Different decals were also part of the package. Silver pin stripes down the ground effects along with "SHELBY" decals replaced the standard red GLH-T decals. A "SHELBY" decal was added to the windshield and a large "GLHS" decal on the driver side rear sail panel. All GLHS cars came with a numbered dash plaque, Mobile 1 valve cover plaque, MOMO shift knob and Shelby leather wrapped steering wheel and A black/yellow overlay sticker was placed at the bottom of the speedometer to read to 135 mph.
