Although its reign may not be permanent.
There are a lot of important factors to consider when buying a pickup truck - how big the bed is, how much it can tow, how much power it has, how much it costs, how many features it has, and of course, how big its cup holders are. We aren't even sure fuel economy cracks the top ten most important considerations for some buyers. Nevertheless, automakers are still working hard to improve the efficiency of their trucks.
To that end, FCA introduced a new eTorque 48-volt mild hybrid system on its V6 and V8 Ram 1500 trucks. We, but EPA figures for the eTorque system weren't available at the time. The EPA has finally published the mpg figures for the Ram 1500 with the eTorque system and the numbers are good, really good.
The most efficient Ram 1500 (aside from the EcoDiesel) is the 3.6-liter V6 with eTorque. In 4X2 configuration, the V6 eTorque achieves 20/25/22 mpg city/highway/combined. The Ford F-150 with the 2.7-liter EcoBoost does achieve 26-mpg on the highway but matches the Ram with 22-mpg combined. With four-wheel-drive, these numbers drop by one in each category. This makes the Ram 1500 eTorque the most fuel-efficient non-diesel full-size truck in America. Only the Ram 1500 EcoDiesel and a few mid-size trucks are able to best it in terms of fuel economy.
The 5.7-liter V8 eTorque isn't quite as efficient, but the numbers are still good. It achieves 17/23/19 mpg city/highway/combined and only the highway figure drops by one-mpg on four-wheel-drive models. This is a nice improvement over non-eTorque V8 models, which achieve around two-mpg less in each category.
Of course, the Ram's reign as the most efficient full-size truck may not last long with the . Chevy's 2.7-liter four-cylinder produces 310 horsepower and 348 lb-ft of torque, which bests the Ram's 3.6-liter V6 with eTorque at 305 hp and 269 lb-ft of torque. We'll have to wait and see because the EPA has yet to publish figures for the Silverado four-cylinder.
