The Wrangler goes hybrid – but it’s not what you think

Those new to the Jeep brand might gawk at a four-cylinder Wrangler, but the Jeep has a strong history with this cylinder count. In fact, the first Jeep, the 1941 Willys MB, came with a four-cylinder. Four-cylinders were offered through the years, with the most recent being in the 1997-2006 Wrangler TJ. In fact, the outgoing Wrangler JK is the only Wrangler/CJ not available with one. That makes the return of a four-cylinder sort of a retro move. Even the engine’s name (Hurricane) is a throwback to older days

The new engine shares nothing with the old Hurricane, of course. It’s a member of FCA’s Global Medium Engine family and is loosely related to Alfa Romeo’s 2.0-liter found in Giulia sedan and Stelvio crossover. In the Wrangler, the Hurricane makes an impressive 270 horsepower at 5,200 rpm and 295 pound-feet of torque at only 3,000 rpm. That torque number actually beats the output of the 3.6-liter V-6 by 35 pound-feet! Better still, the Hurricane makes its power lower in the rev range, likely making it a better choice for serious off-roading. Horsepower-wise, the Hurricane only gives up 15 ponies to the V-6.

The natural trade-off is fuel economy. Neither Jeep nor the EPA have announced official numbers, but expect to see upper 20s on the highway, lower 20s around town, and a combined mpg of around 25.

The Hurricane’s secret is its mild hybrid system. The engine uses a belt-starter-generator to help twist the engine’s crankshaft at lower revs. The system is also designed to provide better auto stop/start performance while also improving low-end throttle response before the turbo spools up.

Impressively, the turbo-four loses no ground in the towing department to the V-6. Jeep says the two-door Wrangler will tow 2,000 pounds and the four-door Wrangler Unlimited will lug 3,500 pounds – regardless of engine choice. Sadly for manual transmission fans, the Hurricane is only offered with the new eight-speed automatic.

The Hurricane will be available in all trim levels from the base Sport, to the luxury-minded Sahara, and even the rugged Rubicon. Pricing has not been announced, but the Hurricane will be an option over the standard 3.6-liter V-6.
