2018 Wrangler engines revealed?

by David Zatz on

Normally reliable source oh2o has weighed in on the engines for the 2018 Jeep Wrangler and 2019 Jeep pickup — and they are a surprise.

Not the gasoline V6 — it remains the 3.6 liter expected by most. Not even the diesel, which many had predicted would be the VM 3.0 V6 used in the Grand Cherokee and Ram 1500, despite capacity issues and Jeep’s long-time reliance on VM fours. As some noted in the Allpar forums, a VM four cylinder would be longer than a V6, leading to packaging problems when the eight-speed automatic is already pressing the issue of the short-wheelbase Wrangler’s length.

The hitherto unexpected third engine is a 2.0 liter Chrysler four-cylinder. Given the date (2019), it will likely be the turbocharged “Hurricane” engine — that is, incidentally, an old Jeep engine name.

Jeep CJs were sold with low-power four-cylinders for decades, with six-cylinder engines being a very late arrival. The Jeeps were lightweight, though, at roughly half the poundage of current  Wranglers. That said, the turbo four should be suitable for road use when connected with the efficient, high-range second generation eight-speed automatics.

What remains to be seen is whether the 3.6 engine will have another set of improvements before the JL starts up in 2018 and the JT (Jeep Truck?) in 2019.
