Jeep Wrangler EcoDiesel gets 29 mpg highway rating
The diesel edition has achieved 25 mpg combined, topping the four-cylinder gasoline engine by 4 mpg.
The 2020 Jeep Wrangler Unlimited EcoDiesel variant has received official fuel efficiency ratings from the Environmental Protection Agency.
The 3.0-liter oil burner has achieved 29 mpg on the highway, 22 mpg in the city and 25 mpg combined, topping the 2.0-liter turbo four-cylinder variant's city/highway/combined rating of 21/22/21 mpg and far exceeding the previous-generation JK Wrangler's 16/20/18 mpg with a 3.6-liter V6.
Depending on an owner's driving habits, the higher fuel efficiency may not translate to any long-term savings due to the higher price of diesel fuel compared to gasoline. The EPA's annual fuel-cost estimate -- based on 15,000 miles and 55-percent city driving -- is $1,850 for the diesel Wrangler, $1,800 for the 2.0-liter gasoline variant, and $1,900 for the 3.6-liter configuration.
The EcoDiesel may still prove popular for buyers who prefer the diesel engine's low-rpm torque when taking the Wrangler off-road.
