2021 Jeep Gladiator EcoDiesel Gets Up To 28 MPG Highway

After introducing the EcoDiesel V6 on the Wrangler last year, Gladiator buyers have access to the mill for the 2021 model year. Newly available EPA fuel consumption ratings indicate that the diesel truck returns 22 miles per gallon in city, 28 mpg highway and 24 mpg combined. For the more rugged Rubicon, the numbers drop slightly to 21 mpg in the city, 27 mpg on the highway, and remain at 24 mpg combined.

For comparison, the same mill in the 2021 Wrangler Unlimited has an EPA fuel mileage rating of 22 mpg city, 29 mpg highway, and 25 mpg combined. Again, the Rubicon is slightly less efficient at 21 mpg in the city, 26 mpg on the highway, and 23 mpg combined.

The 3.0-liter EcoDiesel V6 produces 260 horsepower (194 kilowatts) and 442 pound-feet (600 Newton-meters) and comes exclusively with an eight-speed automatic transmission in the Gladiator and Wrangler. Models equipped with this powertrain have stronger Dana 44 axles at the front and rear, typically for the Rubicon quality of the gas-powered examples.

The Gladiator EcoDiesel in the Sport and Overland categories uses the part-time Command-Trac four-wheel drive system with a low-end 2.72: 1 gear ratio. Going for the Rubicon allows buyers to benefit from a Rock-Track part-time 4WD with 4.0: 1 low range ratio.

The 2021 Gladiator with EcoDiesel will go on sale in the third quarter. Jeep is not yet discussing diesel truck pricing. Rumor has it that the starting number is above $ 40,000, and the Rubicon could start at $ 51,370. It is not yet known whether the new Mojave will be available with diesel. As a rough guide, the powertrain adds $ 6,000 to a Wrangler, which includes $ 4,000 for the engine and $ 2,000 for the mandatory eight-speed automatic.
