AMC’s 4.0-liter inline-6 gas engine is heralded by most Jeep fans as the best engine the brand has ever offered. The engine was discontinued over 15 years ago, but reports are pointing to an entirely new inline-6 that should be arriving in Jeeps soon.
According to Mopar Insiders, who cited “well balanced sources,” Jeep is planning to unveil a brand new turbocharged inline-6 gas engine at the New York Auto Show in April. So far, this report has not been confirmed by Jeep.
The engine, internally designated GME-T6, is believed to be part of parent company Stellantis’ new Global Medium Engine family, and it will mark the return of the inline-6 to Jeep. According to Mopar Insiders’ report, the Wagoneer will receive a high-output variant of this engine first, with less-powerful versions to arrive later in different models. Mopar Insiders also claims that a plug-in hybrid version of the GME-T6 will arrive in 2023.
