Like I said in another thread, "When I worked at the airport I saw a steady stream of Suburbans, Escalades, Expeditions, and Navigators, dressed in black with limo plates, all plying their trade. The REEV drive-train will upend the livery trade." Let's face it, the big black SUVs have replaced the Limo in our time.
Now about the 4Xe label, Jeep quickly used up any equity for that designation by pretending the Wrangler and Grand Cherokee PHEV models were fully electric. Consumers were not properly educated on the pros and cons of this type of hybrid or how to get the most out of it. Then the battery issues and recalls came up. I must point out that the Jeep people are already starting out on the wrong foot saying that the Grand Wagoneer REEV doesn't ever have to be plugged in. Underplaying the battery electric aspect of the REEV is just as bad as overplaying the battery electric aspect of the PHEV.
The legacy Chrysler Corporate brands seem to have extracted themselves from the Euro dictates of the previous Stellantis regime. I think Auburn Hills leadership will find that the Ram REV and Jeep G Wagoneer REEV will enjoy success, despite the absence of government handouts. People who have driven an EV like the performance, but the joy quickly fades away once the limitations of the charging infrastructure become evident. Long time suppliers to the CDJR brands have demonstrated the products and engineering to place IC engine range extenders in smaller vehicles, and now Nissan is offering their 5-in-1 unit to Auburns Hills for their consideration. The choice is now before the Stellantis leadership, write off the recently introduced battery electric vehicles for North America, or offer a range extended option for them, thus recouping the development and tooling costs from the EV debacle.
Finally, is the inverter/generator portion of the range extender drive in the Ram REV and Jeep G Wagoneer REEV an in-house design or from an outside supplier? I ask this because a few of the suppliers have demonstrated products which work in smaller vehicles.
