High-MPG Model Round-Up

The trucking industry news site Trucking Info has a story about the big truck models that get the best fuel economy, noting that more miles per gallon come from truck models that are designed specifically to get more miles out of a gallon of diesel, and that all major builders offer those types of trucks for owners. Among the features that help contribute to improved fuel mileage:

  • Advanced aerodynamics, which come from thousands of hours in a computer simulation and wind-tunnel testing.
  • Down-sped engines, which have cruising speeds 150 to 200 rpm less than normal, which reduces internal friction.
  • Automated manual transmissions, which work with engines and shift themselves through calibrated settings located in electronic controls, which allow the worst driver to perform almost as well as the best.
  • Low-rolling resistance tires, which reduce drag on the rig.

Here are some of the best-performing mpg trucks on the road:

Freightliner Evolution I

International ProStar ES

Kenworth T680 Advantage

Mack Pinnacle

Peterbilt 579 Epiq

Volvo VNL 670

Western Star 5700XE

Each of these trucks combine more than one of the features listed above to provide superior fuel efficiency performance, as well as other features that help improve their fuel economy.

With the new EPA standards being discussed, these trucks may represent the next step between the old and new big rigs, which come with a slightly higher price tag but much greater fuel economy, which, industry experts note, creates a situation where the trucks pay for the higher price tag over a short period of time (as little as two years). As fuel efficiency becomes a spotlighted issue for the industry, the continued improvement of that stat can mean a great deal for truck companies.
