In its five-year strategy announcement for Dodge made in May 2014, Fiat Chrysler Automobiles’ [NYSE:FCAU] target date for redesigning the Challenger and Charger muscle cars was calendar year 2018. In 2015 we heard that the redesign might be delayed until 2019, and now we’re hearing that the delays might stretch even further.

Citing one source at FCA and another at a supplier, Automotive News (subscription required) on Monday reported that the redesigned Challenger and Charger will be delayed until calendar year 2020. The sources said the cars are to adopt FCA’s Giorgio platform, which debuted in the 2017 Alfa Romeo Giulia, and will likely arrive as 2021 models.

The sources also said one of FCA’s large sedans is likely to be discontinued, most likely the Chrysler 300.

According to Automotive News, similar information was conveyed in a document sent to members of Unifor, the Canadian auto workers union. (The Challenger, Charger and 300 are built at a plant in Brampton, Ontario, Canada.) The information also matches a previous report that claimed the redesigned Charger won't arrive until early next decade.

Both the Challenger and Charger are now expected to receive a second significant update to keep them fresh. The first such update was introduced for the 2015 model year.

Updates for the Challenger will be arriving soon. An all-wheel-drive Challenger GT is expected for the 2017 model year and has already shown up on the EPA’s website. A new range-topping model potentially labeled the Challenger ADR is also in the works. This model will get the supercharged 6.2-liter Hellcat V-8 and some much-needed wider tires.

Worryingly, Dodge isn’t the only brand within FCA making headlines for significant delays. Most of Alfa Romeo’s planned models have been delayed and so have, most likely, the sports car for Maserati and the redesigned Grand Cherokee and Wagoneer SUVs for Jeep.

Stay tuned for an update.
