Third generation 1976-1979
The third generation Dodge Colt was effectively made up of two lines: coupes and sedans were of a smaller, Lancer-based series, while the Wagons were based on the new Mitsubishi Galant Sigma.
In late 1976, for the 1977 model year, the smaller A70-series Mitsubishi Lancer became the Dodge Colt, with two-door coupe and four-door sedan bodies. While the wheelbase was only slightly shorter than that of the second generation Colt, overall length was down from 171.1 to 162.6 inches (4346 to 4130 mm).
The new Colt was also referred to as the Dodge Colt "Mileage Maker" to mark it as different from its larger predecessor. Second generation Coupe and Wagon versions remained on sale for the 1977 model year.
The engine was the familiar 4G32 iteration of Mitsubishi's Saturn engine family, of 1597 cc and still with 83 hp at 5,500 rpm. A "Silent Shaft" (balance shaft) version of this engine along with a five-speed manual transmission (instead of the standard four speeds) were part of a "Freeway Cruise" package, which also included a maroon/white paintjob. For 1978 power dropped to 77 hp with the introduction of the "MCA-Jet" high-swirl system.
For 1978 a new, larger, Dodge Colt wagon also arrived, a rebadged Mitsubishi Galant Sigma. It came with the same 1.6-litre MCA-Jet four as the smaller sedans and coupes, but a 2.6-litre, 105 hp (78 kW) Astron engine was an option, as was a five-speed manual. While the last year for the Lancer-based Colts was 1979, the wagon lingered on alongside the front-wheel drive Mirage-based fourth generation until 1981 when it was effectively replaced by the domestic Dodge Aries K wagon.
The larger Mitsubishi Galant Lambda coupé was also marketed as the Dodge Colt Challenger from 1978, although the "Colt" part was later dropped. It shared the chassis as well as the engine options of the Colt wagon.
