Brand New Jeep Engine Coming Next Month

Rumor / 4 Comments

No, it's not a V8.

The 2022 Jeep Grand Wagoneer debuted with only one engine, a potent (but gas guzzling) 6.4-liter HEMI V8 producing 471 horsepower. Sure, the standard Jeep Wagoneer has a slightly more efficient mild-hybrid eTorque setup, but it's still a 5.7-liter HEMI V8 that averages only 18 miles per gallon. We've seen Jeep move further towards electrification with 4xe plug-in hybrid versions of the Wrangler and Grand Cherokee. The 2.0-liter four-cylinder in the 4xe is great, but likely too small for something like the Wagoneer. Hence why Jeep needs a new engine.

Recent rumors suggest Jeep is working on a new turbocharged 3.0-liter inline-six engine, which will also appear under the hood of the next-generation Dodge Challenger. A new report from Mopar Insiders claims this engine could arrive as soon as next month.

The rumor suggest Jeep will reveal its new inline-six (internal code GME-T6) at the 2022 New York International Auto Show in April. This new engine, rumored to be nicknamed "Tornado," will be the first inline-six from Jeep since the company's legendary 4.0-liter unit was replaced in 2007. As a reminder, that engine was an AMC design that lasted from 1964 through 2006, so this new unit has a lot to live up so.

Not much is currently known about this inline-six in terms of power, but we assume it will be comparable to Jeep's smaller 5.7-liter V8, which produces anywhere from 357 to 392 hp. The Wagoneer lineup will be the first vehicles to receive this new engine in a high output form requiring premium fuel. We expect a lower output version later on that can run on regular 87 octane gas. Later in this engine's life cycle, it will find use in a plug-in hybrid model under the 4xe nomenclature.

Jeep is also expected to reveal the long-wheelbase Wagoneer variants. The standard Wagoneer and Grand Wagoneer are already longer than the standard Tahoe, Yukon, Escalade, Expedition, and Navigator, but slightly smaller than the Suburban, Yukon XL, Escalade ESV, Expedition Max, and Navigator L.

Extended versions of these models will put Jeep on top in terms of passenger and cargo space. We can expect to hear official news from Jeep during the first NY Auto Show press day on Wednesday, April 13 2022.
