History

Chrysler was facing a grave financial crisis due to poor business decisions, lack of investment in new products during previous years, and external factors outside of their control as the 1970s ended.
Lynn A. Townsend, chairman from 1967 to 1975, had pursued a hands-off policy of running the company, refusing to spend more than the minimum on new drivetrains or platforms as long as the existing ones continued to sell. Sales of the company's larger cars started dropping after the
1973 OPEC Embargo and an increased amount of company volume consisted of lower profit compact models. Chrysler also had a policy of producing cars regardless of whether a customer ordered them, which was in contrast to AMC, Ford, and GM who only produced vehicles for which they received orders. Soon, they were left with a backlog of unsold inventory which cost money to store and had to resort to the money-losing tactic of rebates to get rid of these excess cars. Compounding these difficulties were new Federal emissions and safety regulations during the 1970s which added more to the production costs of each car. Townsend retired in 1975 and left the reins to
John J. Riccardo, who presided over a slowly-sinking company.
The following year, the compact
Dodge Aspen/Plymouth Volare debuted as replacements for the dated Dodge Dart/Plymouth Valiant, but were rushed into production and ended up with a major string of quality control problems that led to them being one of the most recalled cars in US history. In 1977, Riccardo petitioned newly elected US president

for a Federal bailout, but Carter would not consider the idea as long as Chrysler's present management was in charge. In January 1978, Chrysler released the Dodge Omni/Plymouth Horizon, a US adaption of the European Simca Horizon and the first domestic-built FWD subcompacts. They came out in a year when larger cars were in demand and dealers struggled to move them from lots, costing the hard-pressed company yet more money. Ford president

was fired on July 13, 1978, and three months later, Chrysler offered him the position of company president. By this point, the smallest of the Big Three American automakers was close to collapse, struggling from the unexpected poor sales of the Omni, the fallout from the Aspen recalls, and the decision to discontinue full-sized Dodges and Plymouths in 1978, leaving it without a full-sized car in a year of strong sales for them. Since 1976, quality control on Chrysler vehicles had become worse.
Although the K-platform had been designed during 1978, the failing company could not afford by this point to put them into production. Thus, Iacocca and Riccardo decided to repeat the original 1977 request for government assistance, but since the Carter Administration would not offer any help until the existing management was removed, Riccardo stepped down as chairman and gave Iacocca the job. During a series of Congressional hearings, Lee Iacocca made his case for a Federal bailout of Chrysler, citing past
bailouts of the railroad industry and aerospace company
Lockheed as precedent. He argued that thousands of American jobs would be saved and the company had been consciously attempting to build modern, economical cars such as the Omni, but fate had dealt them a bad hand. Iacocca also stated that excessive government regulations were costing needless money. Congress approved the bailout after Chrysler detailed the plans for their new FWD platform and the first handful of K-cars trickled off the assembly line at Detroit's Jefferson Avenue plant in late 1980.
The Reliant and Aries were
downsized replacements for the six-passenger Volare and Aspen, which in turn were modernized version of the original Valiant and Dart compact cars of the 1960s. Based on experience gained with subcompact Omni/Horizon of 1978, the roomier K-cars set out to build a family sized car with a front-wheel drive design powered by a four-cylinder engine. They were offered as two and four door notchback sedans and wagons and retained six-passenger seating on two bench seats. While the
Chevrolet Citation introduced front-wheel drive in the 1980 model year to replace the Nova, its unusual styling and problems with recalls hampered its success. They achieved nearly a million in sales between the two original nameplates before being rebadged and upgraded, not counting the numerous stretched, sporty, or minivan derivatives. Ford did not replace its family-sized Fairmont/Granada/LTD with a front-wheel drive design until the 1986

would be marketed as upscale compacts rather than family sedans.
Initial advertisements for the Aries were done in red, white, and blue and emphasized American industry's desire to answer the challenge of Japanese products and also promoted the low $5,880 base price. Since Chrysler was so financially strapped, early promotional shots featured the same car, but with Dodge and Plymouth badges and trim swapped. In 1981, sales of the Reliant and Aries got off to a slow, but early start and can be attributed to Chrysler's inadequate preparation. Instead of producing a sufficient amount of base models, Chrysler was producing a larger number of ''SE'' and ''Custom'' models. When consumers arrived at Plymouth (and Dodge) dealers, they were shocked to find that the Reliant they were planning on purchasing would end up costing hundreds or thousands of dollars more. As a result of this, Chrysler corrected this and began building more base models and sales of the Reliant and Aries skyrocketed.
The Reliant and Aries were available in standard "base", mid-level ''Custom'', and high-end ''SE'' (later renamed ''LE'') trim levels. Unlike the

was not available in base trim. "SE" Reliant/Aries wagons came standard with exterior woodtone siding, although it could be deleted. All models except base could be ordered with front bucket seats rather than the standard bench. By 1987, though, bucket seats became standard and bench seats were optional without charge.
Changes through the years


*1982: A new hood ornament (changed from either a Plymouth "frog legs" hood ornament or a Dodge badge mounted flat on the hood to an upright Chrysler Pentastar), a counterbalanced hood, and black painted valve cover on the 2.2L engine (vs. the former blue). 1981 and 1982 were the only two years when a factory installed sunroof on coupes and sedans could be ordered. Actual production numbers are not known.
*1983: A blacked out grille is made standard on the Aries. Also, the four-door sedan and station wagon models finally received roll-down rear door windows versus the former stationary glass with rear quarter pop-out panes.
*1984: The hood ornament was removed and the Chrysler Pentastar moved to the grille; the

-styled grille used on the Reliant was modified. Also, the tail lights received chrome trim, and the interior received a padded dash and new black instrument cluster with round gauges.
*1985: The first major changes occurred when the Ks received a new, rounder front fascia, featuring either a new egg-crate or crosshair
grille for the Plymouth and Dodge that was the same height as the headlights (rather than going all the way up to the hood as with previous model years). A new rear fascia featuring five-section taillights. A new trim line, the top-tier LE ("Luxury Edition"), was added (it also replaced the Custom trim level on the wagon). The base engine was a transverse mounted Chrysler designed 2.2 L (135 cid)

*1988: All Reliant models were renamed ''Reliant'' ''America'' in the U.S., and ''Reliant'' ''Canada,'' in Canada, and was offered in one "LE" trim level. This marketing strategy was also practiced with the
Dodge Omni America/Plymouth Horizon America in 1988, and as a separate base series for the
Dodge Shadow/Plymouth Sundance twins for 1992. It is also the last year for the station wagons.
After 1987, the Reliant and Aries underwent only minor changes throughout the rest of its production run. The last K-car rolled off the assembly line on December 9, 1988. The 1989 Reliant and Aries were carryovers from the 1988 model year and only the America and Canada trims were available on these models. No station wagon models were sold in 1989. The Reliant was replaced by the
Acclaim for 1989, while the Aries was replaced by the
Spirit.
