The Wrangler JK is only available with one engine (3.6L Pentastar V6 engine), whether it is the Wrangler or Wrangler Unlimited. That same engine returns to the Wrangler JL model, but it’s been tweaked a little bit. The new tweaked engine is able to generate up to 285 horsepower and 260 lb-ft of torque, and it can be paired to the standard six-speed manual transmission or the new available eight-speed automatic transmission. The engine also comes standard with electric start-stop (ESS), a technology to conserve fuel while the engine idles. With this tech, consumers can expect their Jeep Wrangler JL to have an average fuel economy of 17 mpg in the city and 23 mpg on the highway if paired to the manual transmission; otherwise it’s 18 mpg in the city with the automatic transmission.
Another change between the Wrangler JK and Wrangler JL is that the Wrangler JL is also available with two new engine options. One of the new options is a turbocharged 2.0-liter four-cylinder engine, able to generate its best-in-class 270 horsepower and 295 lb.-ft. of torque. Paired to the eight-speed automatic transmission, this turbocharged engine is the first step for Jeep to dip into hybrid technology. Designed with a hybrid system, eTorque, the Wrangler JL with the turbocharged engine also has auto stop/start, electric power assist, extended fuel shut-off, transmission shift management, intelligent battery charging, and regenerative braking.
