All ranges: Hurricane adds power, economy to Wagoneer lineup

The battery-electric Wagoneer S might be coming, but the Wagoneer and Grand Wagoneer are already on sale. They started out with 5.7 and 6.4 Hemi engines, but these have largely been replaced already by two varieties of the “Hurricane” twin-turbo straight six. The standard output variety produces more power and torque than the 5.7 Hemi V8, using the same midgrade fuel; the high output version outpowers the 6.4 Hemi V8, using the same premium fuel.

Hurricane Twin Turbo Engine

Here is what it looks like in table form:

ModelV8 CityI-6 CityV8 HWI-6 HW
Wagoneer RWD16171820
Wagoneer 4×415161719
Grand 4×413141517
Grand L 4×413141516

(HW is highway mileage)

The Hurricane turbo-six provides an extra 1 mpg in the city cycle—which might not seem like much, but one mile per gallon is hard to get in such a heavy vehicle, especially while adding power. It’s a roughly 6% gain in economy, based on the rounded numbers we see here. The Hurricane also provides an extra 2 mpg on the highway, except in the big-and-heavy Grand Wagoneer L.

Wagoneer owners aren’t exactly going to be slipping gas station attendants a twenty and filling their tank, especially given the engines’ need for midgrade and premium fuel, but over the course of a year the savings should add up quickly.
