I think Stellantis should develop a smaller high performance small-block V8 (perhaps 4.0L or something like that) for the American market only (since they can't go about 3.0L in the European market). It would then be able to meet fuel economy and emissions requirements for a long time to come, but could still put out really high HP numbers and would have the sound the American market demands. They could sell this on the highest performance trims of the Dodge, Ram, and Jeep products and demand a price premium for it. I hope the I-6 isn't the only option they are planning to have for the next decade, even though it is an impressive engine. It's more like what the 6.4L hemi use to be, the 2nd tier high performance engine. They still need that flagship engine.
