Dodge Omni

The Dodge Omni (also known as the Plymouth Horizon) is a subcompact car that was manufactured and marketed by Chrysler Corporation from the 1978 to 1990 model years. The first front-wheel drive Chrysler vehicles, the Omni and Horizon were the first American cars sold with front-wheel drive and a transverse-mounted, four-cylinder engine. The Omni/Horizon were the central model lines of the Chrysler L platform, an evolution of the Chrysler Horizon designed by Chrysler Europe. Heavily inspired by the Volkswagen Rabbit, the model line was sold exclusively as a five-door hatchback. In the 1980s, the L platform chassis architecture subsequently also supported 3-door coupes and a 2-door pickup. Overshadowed by the introduction of the K-cars, the Omni/Horizon saw few running changes over eleven years of production. While the model line helped Chrysler escape its dire financial situation, its discontinuation was necessitated by advances in front collision requirements. In addition, Chrysler had introduced the Dodge Shadow and Plymouth Sundance hatchback sedans for 1987 to replace the model line, with the Neon replacing both generations for 1993. From 1977 to 1987, Chrysler manufactured the Omni and Horizon (alongside the entire L platform model range) at its Belvidere Assembly facility (Belvidere, Illinois). In 1987, production shifted to the AMC Kenosha Plant (Kenosha, Wisconsin), finally moving to the Jefferson Avenue Assembly (Detroit, Michigan) facility in 1989. The Omni/Horizon were the final model lines produced at the latter two facilities. In total, approximately 2.5 million vehicles were produced; the Plymouth Horizon is the final Plymouth model to outsell its Dodge counterpart.

Development

=== Background === In the early 1970s, Chrysler Corporation had repeatedly announced it would enter the North American small car market to compete with Chevrolet Vega, Ford Pinto and AMC Gremlin, by developing and manufacturing its own domestic small car, known as its Project R-429 — only to repeatedly delay the project. In an attempt to stave off the U.S. small car competition, the company increased its stake to 77% of Simca in 1963 and had taken control of the Rootes Group by mid-1964, marketing numerous Simca and Rootes models, e.g. the Simca 1204 and Sunbeam Arrow via a new Simca-Rootes Division, formed in 1966 — with 850 dealers selling four Simca models and 400 dealers selling four Rootes models. Results were dismal, and in late 1969, Chrysler announced it would market its Rootes and Simca products directly via its Chrysler-Plymouth Division. Chrysler introduced its newly developed Hillman Avenger to the U.S. and Canadian market for model years 1971-1973 as the rebadged Plymouth Cricket, directly via its Plymouth dealerships — as a 4-door saloon/sedan (and a 5-door station wagon for MY 1972). The Cricket, and the Mitsubishi-built Colt, marketed concurrently by Dodge dealerships, were both seen in the industry as stop-gap measures until Chrysler could design a small car to be domestically manufactured. The Cricket in particular failed to resonate in the market. At the same time Chrysler marketed these captive imports, Chrysler executives denounced the concept of subcompact cars, Chrysler's Chairman, Lynn A. Townsend saying "the subcompacts are just too small, the American people won't climb into them. They have to give up too much in creature comfort. In 1974, Townsend sent an American management team to Chrysler Europe to find a suitable small-car design for the U

Model overview

The Dodge Omni and Plymouth Horizon are five-door hatchbacks sold in North America. Introduced in January 1978, the model line was developed in tandem with Chrysler Europe, leading to the namesake Chrysler Horizon. Chrysler also sold multiple variants of the model line derived from the same chassis, including 2+2 coupes and coupe utility pickup trucks. The Omni and Horizon appeared at a critical time for Chrysler, when the company was on the brink of bankruptcy and sought government support to survive. However, the L-bodies miscarried at first, since 1978 was a year of strong sales for larger cars and demand for compacts and subcompacts noticeably shrank. These initial poor sales of the cars contributed to Chrysler's financial woes at the time, but when the company requested federal assistance, the Omni was an important piece of evidence that they were attempting to compete with imports and build small, fuel-efficient cars and might be worth saving. For the three years leading up to the introduction of Chrysler's K-cars, the Omni/Horizon was Chrysler's best selling model line. Produced nearly unchanged from the 1978 to the 1990 model years, Chrysler had beaten out Ford and General Motors to the market with a domestically produced front-wheel drive car to challenge the VW Rabbit. Chassis. The Dodge Omni and Plymouth Horizon use the front-wheel drive Chrysler L platform on a 99.2-inch wheelbase (shared with its European namesake). Initially designed by Chrysler Europe, Chrysler Corporation made substantial changes to the suspension design for the American market. In contrast to the Chrysler Horizon, which has a front torsion bar suspension, the model line uses front MacPherson struts. The rear suspension uses a semi-independent twist-beam layout in contrast to the indepen

Production

From 1977 to 1987, Chrysler Corporation assembled the Omni and Horizon hatchbacks at its Belvidere Assembly Plant (Belvidere, Illinois); the facility assembled the entire line of L-body vehicles, including the Dodge Omni 024, Plymouth Horizon TC3, Dodge Charger, Plymouth Turismo, Dodge Rampage, and Plymouth Scamp. In 1985, Chrysler entered an agreement with American Motors Corporation (AMC) to produce Chrysler M-body vehicles at its Kenosha, Wisconsin facility (supplementing AMC production of Renault-badged vehicles). In 1987, Chrysler and AMC agreed to add the Omni/Horizon to the contract; for 1988, it had discontinued the L-body Charger/Turismo and Belvidere Assembly was being retooled for the production of the AC-body/AY-body sedans (Dodge Dynasty to the Chrysler Imperial). M-body sedans were built at the Kenosha Main plant, while L-bodies were built at Kenosha Lakefront. At the end of December 1988, Chrysler ended automobile production in the AMC Kenosha facilities, relocating Omni/Horizon production to its Jefferson Avenue facility. Production Figures:

Variants

Following the introduction of the five-door Omni/Horizon, Chrysler introduced several additional versions of the L-body platform, including the Dodge 024/Plymouth TC3 three-door hatchbacks (later the Dodge Charger/Plymouth Turismo) and the Dodge Rampage/Plymouth Scamp coupé utility pickup truck. As a hot hatch, Chrysler introduced the turbocharged Omni GLH (later the Shelby GLH-S). Dodge Omni 024/Dodge Charger. For 1979, Chrysler introduced a hatchback coupe version of the Omni/Horizon, named the Dodge Omni 024 and Plymouth Horizon TC3. Using an L-body chassis (shortened to a 96.6-inch wheelbase), the 024/TC3 coupes shared no external bodywork with the five-door hatchbacks. Sharing the same powertrain as the Omni and Horizon, the coupes were largely designed for appearance over performance. For 1982, the O24/TC3 were renamed Dodge Charger and Plymouth Turismo. While again offering the same powertrain as the five-door hatchbacks, the 2.2 L high-output engine was added to create the Dodge Shelby Charger/Plymouth Turismo Duster. For 1984, the coupes received updated exterior styling (distinguished by a quad-headlamp front fascia). For 1985 and 1986, the Shelby Charger adopted the 146 hp (109 kW) engine of the Omni GLH-T. Following the 1987 model year, the Dodge Charger/Plymouth Turismo were replaced by the Dodge Shadow/Plymouth Sundance; Dodge would not again remarket a Charger until the 2005 model year. The final 1000 Dodge Shelby Chargers were built as Shelby Charger GLHS vehicles with a 175 hp (130 kW) 2.2 L Turbo II engine, upgraded transmission, brakes, and suspension, and the deletion of all Dodge badging. Dodge Rampage/Plymouth Scamp. For 1982, Chrysler introduced a coupe utility pickup derived from the L-body chassis, named the Dodge Rampage. The first front-wheel

Legacy

At the time of its 1978 launch, the Omni and Horizon would play a significant role in the survival of Chrysler Corporation. While initially struggling against rebounding sales of larger vehicles, nearly 200,000 examples of the combined model line were sold in the first model year. In contrast to most Chrysler model lines, the Plymouth Horizon would outsell the Dodge Omni (some years, by a significant margin), with the exception of the final 1989 and 1990 model years. As the Omni/Horizon became the best-selling Chrysler model line between 1978 and 1980, it would play a major role in Chrysler securing government-backed funding in 1979. The model line was evidence that Chrysler was attempting to develop more fuel-efficient vehicles competitive with automakers around the world. Along with ensuring the continued survival of the company, the $1.5 billion loans ($6.65 billion in 2025) allowed Chrysler to finish the development of its compact/mid-size K-Car program and its minivans, two of its most profitable model lines during the 1980s.

Consumer Reports review

Shortly after their introduction, Consumer Reports tested the Omni and Horizon and reported that it lost control in hard maneuvering. As front-wheel-drive cars were still considered a new idea in the American automotive industry, the allegation received extensive mainstream coverage, including a piece in Time magazine. Other automotive media reported no problems and said the Consumer Reports test did not approximate real-world driving conditions. In response to the Consumer Reports article, Chrysler modified the car to add a steering damper and a lighter-weight steering wheel.
