The EPA has officially released its assessment of the 2020 Jeep Wrangler EcoDiesel. The EcoDiesel is only available as a 4-door with an 8-speed automatic and in that configuration, the EcoDiesel manages to get 29 mpg highway, 22 mpg city, and 25 combined. That is slightly better than a 4x4 Ram 1500 with the same powertrain. The next closest model in terms of fuel efficiency is the 2-door, 4-cylinder, manual transmission, rear-wheel drive Wrangler at 24 highway mpg, 22 city mpg, and 23 combined.
The diesel engine is a $4,000 option though so you may not ultimately save money. Instead, Jeep believes the EcoDiesel option is best suited for those who need the gobs of torque generated by the V6 diesel when going off-road. With 260 horsepower and 442 lb.-ft of torque, the Wrangler EcoDiesel has torque in spades. To the dismay of many, the Ecodiesel does come standard with electronic stop/start.
If diesel isn't your thing, there is the 2.0T 4-cylinder which produces 270 horsepower and 295 lb.-ft of torque or the 3.6-liter Pentastar V6 which produces 285 horsepower and 260 lb.-ft of torque. Both engines also come with stop/start or can be upgraded to the eTorque system that smooths out the torque band and either engine is available with a manual transmission or 8-speed automatic.
