What’s behind the 2017 diesel delays?

by David Zatz on

2017 Ram and Jeep diesels are reportedly being delayed — but the same is true of diesel engines from nearly all automakers, as the EPA rushes to crack down on diesel emissions cheats.

So far, according to Automotive News’ groundbreaking report, only Jaguar and BMW have been given permission to sell diesels in the US. Others have to wait, pending testing clearance, thanks to Audi-Volkswagen cheats.


New tests take longer and are not as predictable as the old ones, so manufacturers can’t use detection software effectively.

Ram 1500s and Jeep Grand Cherokees use VM diesel engines, while the Ram ProMaster has a Fiat diesel option. VM is now owned by FCA.

According to an FCA spokesman, “certification is pending.”


So far, the agency has not found any evidence of cheats from anyone but Volkswagen, Audi, and Porsche. The more sophisticated testing, though, has delayed approval of many vehicles. For that reason, GM is still building 2016 Colorado and Canyon diesels while they wait for 2017 certification.

There are still many Ram 1500 diesels and Grand Cherokee diesels available for sale at dealerships, and it seems likely both will see 2017. However, Mercedes, according to Automotive News, has dropped its forthcoming diesel C-series completely.
