A recent report says that the new 3.8-liter gas V6 in the 2020 Nissan Frontier will get a fuel economy rating of 19 city / 24 highway / 20 combined MPG for the 2WD model. The 2020 Frontier 4×4 is said to get 17 city / 23 highway / 19 combined MPG.
This report is not yet published by Nissan or the EPA, but it is available at Motor1.com based on insider information from Nissan.
The new 3.8-liter V6 uses direct injection and lots of latest technology to produce 310 horsepower and 281 lb-ft of torque. The new engine is mated to a 9-speed automatic transmission. This is the only engine / transmission combination for the new Frontier. The old 2.5-liter I4, 4.0-liter V6, and manual transmission options are all discontinued.
We already put the new Frontier through a battery of on-road and off-road tests. You can see it all in the videos below. I ran the truck at 70 mph on the highway on our 66 mile loop. The truck returned a pump-verified 22.5 MPG during our test. 23 MPG highway rating for the 4×4 truck is very realistic.
This rating is also better than the 2020 Toyota Tacoma gas V6 and the 2020 Jeep Gladiator gas V6.
We also put the new Frontier on our difficult Iron Clads off-road trail in the Rocky Mountains. Here is what happened.
