When the next-generation Jeep Wrangler debuts, a new turbocharged four-cylinder cranking out around 300 horsepower is likely to be an option.



According to Automotive News, a source inside the company has confirmed the existence of the new direct-injected inline four-cylinder engine with a twin-scroll turbocharger and an aluminum block that makes 300 horsepower.

Codenamed Hurricane, the engine will be built at the Trenton Engine Complex in Michigan, which currently builds the 3.6-liter Pentastar V6 engine. FCA has already announced a $75 million investment into the complex to build the new engine.

When the new Wrangler debuts, this turbo four will likely be mated to an eight-speed automatic transmission and sold as the economic option. Eventually, a diesel and hybrid powertrain are also expected to join the Wrangler’s portfolio, once again in a play to increase fuel economy.

This is the trend to expect for all vehicles, since there will be no relief in Gov Safety/Crash standards that will keep the weight of the vehicles high, the consumer demands that want bigger vehicles keeping the size and poor aerodynamics up high as well, increasing emission standards that will cut down the efficiency potential of the engines but higher and higher fuel efficiency CAFE standards are still looming.


So, high dollar gold plated motors that can improve efficiency on the margins, like using Turbo's are on the horizon.


Nothing wrong with turbo's and the quality has probably improved that the concern that one day, you'd need to replace the turbo when the car still had a lot of life left in it, which is pretty hefty bill. That might be gone and they last much longer now. Off road and Turbo's isn't always the best combo, but like they said it may be a base engine option for those that get Wranglers but won't be off-roading much.

Emissions is what kills Diesels in the U.S. its a leap frog game with the technology and the ever increasing standards. Chrysler Diesels can pass emissions in country X, Y and Z for the next 3 years, but can't pass emissions in the U.S. So we moan while export Jeeps to several countries get Diesels but we can't get them here. Don't worry, in five years, they'll have a new diesel engine that can pass emissions in the U.S. and those other countries increased their standards that it can't pass, so we get a diesel for a couple of years, while they can't. Just wait a couple more years and we'll swap again.


I "think" turbos are harder to get past emissions. But the mileage benefits are enough that its worth the extra work to get those gains for CAFE standards. I'm guessing and could be wrong, but the combination of Turbo and Diesel might be too hard for Chrysler/Fiat at this point.
