The Environmental Protection Agency (EPA) has released its official numbers for the 2018 Jeep Wrangler JL models equipped with the turbocharged 2.0-liter four-cylinder. Although the 2.0-liter is only mated with the 8-speed automatic, fuel economy ratings are modest against the standard 3.6-liter Pentastar V-6.
The all-new 2.0-liter turbocharged inline four-cylinder engine with eTorque technology is rated a best-in-class 270 horsepower and 295 lb.-ft. of torque and mated to a new eight-speed automatic transmission. The 2.0-liter turbocharged inline four-cylinder (I-4) engine’s torque output surpasses that of the Pentastar V-6 engine.
The eTorque system’s hybrid functions include auto stop/start, electric power assist, extended fuel shut-off, transmission shift management, intelligent battery charging and regenerative braking. Both the engine and fuel flow may be turned off during stops, coasting or when the engine is decelerating.
For the city, the two-door 2.0-liter Wrangler JL gets 23 mpg, while the four-door Unlimited models get a rating 22 mpg. On the highway, the two-door manages to get 25 mpg and the Unlimited model gets 24 mpg, respectively. Combined economy for the two-door is 24 mpg, while the bigger Unlimited is 22 mpg. All 2.0-liter models are required to run premium gasoline, so the EPA estimates its annual fuel cost at $2,100. Wrangler Unlimited models are estimated to have an annual fuel cost at $2,300.
For comparison, the 2018 Jeep Wrangler JL models with the 3.6-liter Pentastar V-6 can run regular gasoline. Two transmissions are offered. A 6-speed manual which is standard, or the optional 8-speed automatic can be equipped for an additional $2,000.
While the 8-speed automatic Pentastar V-6 models are the most efficient of the V-6 offerings. The fuel economy for both the two-door and Unlimited JL are the same, a city rating of 18 mpg, 23 mpg on the highway and 20 mpg combined. Although you can use regular gasoline with the Pentastar V-6, the EPA estimates annual fuel cost for the V-6 to be $2,150. That is $50 more a year for two-door buyers, and $150 less for Unlimited purchasers. Something to keep in mind when you realize that the turbocharged 2.0-liter four-cylinder is a $1,000 option over the V-6 automatic models.
