for the 1981 model year, featuring a
transverse engine,
front-wheel drive, independent front and semi-independent rear
suspension configuration—a stark departure from the company's previous reliance on
solid axle,
rear-drive unibody configurations during the 1970s. Derived from Chrysler's L-cars, the
Plymouth Horizon and
Dodge Omni, the platform was developed just as the company faltered in the market, at first underpinning a modest range of compact/mid-size sedans and wagons—and eventually underpinning nearly fifty different models, including
all-wheel drive variants—and playing a vital role in the company's subsequent resurgence.
Common platforms
Use of a common platform is a widely used practice for reducing the number of parts and engineering time. Before creating the K platform, Chrysler was building vehicles from a small number of common platforms (e.g. F/L/J/M and R); however there were very few common parts among the different models.
Chrysler CEO
Lee Iacocca
Lido Anthony "Lee" Iacocca ( ; October 15, 1924 – July 2, 2019) was an American automobile executive best known for the development of the Ford Mustang, Continental Mark III, and Ford Pinto cars while at the Ford Motor Company in the 1960s, an ...
claimed that the huge number of parts in inventory and the complexity of building many completely different versions of vehicles was one reason Chrysler was losing money, and directed the engineers to focus on making a larger number of common parts where they would not be visible to customers; this was already common practice in Japan and Germany and would help to make the K-cars profitable even at low prices.
Arriving on the brink of Chrysler's near certain financial collapse, the new platform had a dramatic effect, helping Chrysler report a profit in October 1980 of $10 million ($ in dollars ), its first profit in two years.

division models. The platform interchangeability saved production and purchasing costs, initially costing Chrysler $1 billion over three years to develop ($ in dollars ), but only costing $50 million ($ in dollars ) to generate the second group of badge-engineered variants, the LeBaron and Dodge 400.
Within two years, the K platform vehicles accounted for roughly 50% of Chrysler's operating profits.
In 1984, ''
The New York Times'' said, "Not only did
-carsalmost single handedly save Chrysler from certain death, they also provided the company with a vehicle that could be stretched, smoothed, poked, chopped and trimmed to create almost a dozen different models."
In 1984, David Lewis, auto industry historian and professor of business history at the
University of Michigan said no platform "in the history of the automobile industry has so dramatically allowed a company to survive in such a substantial way. No company has been down so low, in such difficult straits, and then depended on practically a single product to bring it back."

's answer to the import pressure was the K platform, which featured an economical 4-cylinder engine,
front-wheel drive, and used many modern weight-reducing measures such as replacing metal styling parts with plastic interior and exterior components.
The K-cars (
Dodge Aries,
Plymouth Reliant,
Chrysler LeBaron,
Dodge 400, and, in Mexico,
Dodge Dart) sold over 2 million vehicles from 1981 to 1988, and around 100,000 in their final year, 1989.
The manual transmission provided acceleration of in 10 seconds, while the automatic was between 13 and 14 seconds, similar to or better than most competitors, while fuel economy was rated by the EPA at city and highway with the manual transmission. All had a wheelbase. The overall length of the two- and four-door models was . The wagon was longer. The vehicles had an approximate fuel tank. The coupe and sedan had approximately of luggage space; the wagons, with the rear seat upright and about when folded down.
Numerous improvements to the sound insulation and general feel were made for the model year 1983. In 1985, the Reliant, Aries, and LeBaron received a facelift, with a rounded front fascia, smoother hood, and bigger taillights. In 1986, the cars began using fuel injection on the 2.2-liter
engine and a 2.5-liter
engine replaced the arguably unreliable Mitsubishi 2.6-liter engine, which was notorious for leaking oil and generated nicknames like "Mr. Squishy" or "Bitsumishi."
They were initially very profitable, and Iacocca credited them with allowing the company to pay off its bankruptcy loans early.
Derivatives

The K-derivatives offered a large variety of engines depending on year and model. Four-cylinder engines were initially equipped with carburetors; fuel injection was phased in beginning in 1986. Engine output ranged from to . Most vehicles had the or
