When we heard the new JL model of the Jeep Wrangler would be offered with a 2.0-liter turbocharged four-cylinder engine the first thought was this version would be more efficient than the previous model. While the new version of the Wrangler with the four-cylinder engine attached to the eight-speed automatic transmission is a bit more efficient than the Pentastar V6, the cost difference is negligible over the course of a year because the turbocharged engine requires premium gasoline to operate properly, making it more expensive to fill up at the pump.
Looking at the numbers we find that the new turbo four shows up with 23 city/25 hwy mpg to offer a 24 combined rating. Using the estimated cost of premium gasoline and average driving miles, the cost per year for this model at the pump will be $2,100. This number decreases for the Unlimited model which offers you 22 city/24 hwy mpg which is a 23 combined rating equating to an estimated annual fuel cost of $2,300. This may sound affordable if you know what the V6 has to offer, but let’s take a look at the numbers.
The 3.6-liter Pentastar V6 engine, which has been the stalwart performer for the Jeep Wrangler for years, shows up at 18 city/23 hwy mpg or a combined result of 20 mpg when paired to the eight-speed automatic transmission. This engine uses regular gasoline, which offers you an average annual cost of $2,150 to fuel the ride. The Unlimited model offers you the same results as the base version to give you cost savings over the smaller engine. As you can see, the cost to fill the Jeep Wrangler is negligible between the two engines because of the need for premium fuel in the turbocharged version.
Making the Difference in the Wrangler
If the cost of fuel is negligible per year in either model, why would you choose the smaller turbocharged engine for the ride? The difference you’re going to find for the two powertrains starts with the power output. When you get out on the trails, the more torque you can have in the vehicle you drive, the better off you’re going to be when you crawl around on the loose dirt. The smaller engine offers you 295 lb.-ft. of torque while the V6 shows up with a number of 260 lb.-ft. making a difference in the choice you want to make.
Of course, if you want to row your own gears, you’ll only be able to choose the V6 model which is offered with the six-speed manual transmission that you want to enjoy. The four-cylinder engine is only offered with the eight-speed automatic. There’s plenty to choose in the Jeep Wrangler and now that we have at least a pair of engines to choose from the Wrangler is more diverse than it ever has been. Don’t be fooled into thinking you’re saving money on gas, but make the right choice for the power you need when you’re looking for more torque for the ride.
