Stellantis (Chrysler, Dodge, RAM, Jeep, etc) also has a new engine -- a straight-six turbo, in this case. From https://www.caranddriver.com/reviews/a41531745/2023-jeep-wagoneer-l-grand-wagoneer-l-by-the-numbers/ --

There's a genuine car-enthusiast angle to all of this. . . . It's Chrysler's all-new "Hurricane" twin-turbo inline-six—not bent but straight, you've read that correctly—belting out 420 or 510 horsepower, your choice. This costly jewel-like revelation is a rev-happy 3.0-liter dervish that would stand us on our ears if it ever powered something as minuscule as, say, an automobile.

This engine offers bits to make engineers weep: a water-to-air intercooler, twin oil pickups in the sump, and a compression ratio as high as 10.4:1. The turbos aren't sequential, instead serving three holes per, and the low-end torque is plentiful. In fact, how does this sound: 500 pound-feet from the high-output version, which ought to suffice for your 9000-pound horse trailer. Moreover, the glistening alloy block is less than 29 inches long and has been dyno-tortured almost flat on its side. Meaning it will fit in almost any vehicle. Except, at Chrysler, which? A grumpy old Charger? Nevertheless, for the second time in its storied career, the iron-block Hemi should be dropped at the curb.
