Jeep Grand Wagoneer EREV, Ram 1500 REV Slip Again

The Grand Wagoneer EREV was supposed to begin production in May, making the new November target roughly six months later than the timeline Stellantis had set earlier this year. Supplier memos cited by Automotive News point to the revised Warren Truck date. The Ram 1500 REV, however, takes the larger hit, moving to mid-April 2027 from a mid-2026 window originally, a delay of about nine months. As recently as this month, Ram's consumer-facing site had listed a late-2026 window for the truck.

Neither change came through a formal public announcement. Instead, recent reporting ties both slips to updated supplier schedules rather than any official statement from the company. In its own messaging, Stellantis is not describing the Grand Wagoneer situation as a delay. Rather, company spokespeople maintain the SUV remains on track for a 2026 launch, just later in the year than buyers were first told.

Supplier sources identify the shared powertrain as the sticking point, not the vehicles themselves. Two executives told Automotive News the additional months are intended to smooth the rollout of a 400-volt battery and electric motor combination used across both extended-range programs. As a result, that common hardware links the two vehicles' schedules, so a snag or a fix on one program tends to move the other's calendar as well, particularly given that both rely on the same series-hybrid layout.

The REV badge has already changed meaning once. Ram originally applied the 1500 REV name to a planned all-electric pickup, then dropped that battery-electric truck and reassigned the badge to the range-extended model that now shares hardware with the Grand Wagoneer EREV. Consequently, the revised timing pushes Ram's extended-range pickup behind rival electric and range-extended trucks already on sale or arriving sooner, even as Stellantis leans harder on the EREV strategy following the cancellation of the original all-electric Ram 1500 REV.

Both vehicles are positioned as proof that Stellantis retains an electrification plan after walking back several pure EV launches, which therefore raises the stakes on any further calendar movement tied to their shared electric hardware.
