Update 2: The document has been removed from NHTSA's website.
We already knew that the next-generation Jeep Wrangler would offer two engines this time around, a V6 and a new turbocharged four-cylinder. Documentation from FCA to NHTSA that JL Wrangler Forums discovered suggests the V6 will become the entry-level engine with the same 285 horsepower as the current one, while the turbo 2.0-liter inline-four takes the top spot with 368 horsepower. However, we're now hearing that figure isn't accurate.
That's an all-around impressive four-cylinder – and obviously likely too good to be true. Besides making about 80 more horsepower than its bigger V6 cousin, it would also be the second most powerful four-cylinder available in the United States. It would only be 7 horsepower shy of the current four-pot power champ, the Mercedes-Benz CLA45, which makes 375 horsepower. It's also 18 horsepower ahead of the next closest engine, the turbo four in the Focus RS that makes 350 horsepower.
If you do decide to pick up a 2018 Wrangler with the four-cylinder, you'll have to settle for an automatic transmission. Only the V6 will be available with both an automatic and manual transmission. Both engines should be available at launch, which we expect to come shortly after an expected reveal at the Los Angeles auto show. The FCA documentation also suggests that the four-door model will be the first body style available, with the two-door arriving slightly later.
