The Challenge of Standardizing Aerodynamic Testing

One of the new testing methods allowed for EPA SmartWay verification is wind tunnel testing. Here a scale model is prepped carefully before the test; small irregularities can make a big difference in the outcome.

By Jim Park

Aero device manufacturers now have a choice of test methods to prove the effectiveness of their devices. Are consumers any better off?

Test Drive: Kenworth T680 Advantage

The package includes SmartWay-certified tires. We had Bridgestone Greatec M835s. Buyers can choose between wide-base single wheels and tires or fuel-efficient duals. Photo: Jim Park

A new powertrain, enhanced aerodynamics and light-weighting make the T680 Advantage the most fuel-efficient Kenworth ever.

Test Drive: Oshkosh S-Series Mixer

The front-facing barrel and chute on this Oshkosh S-Series allow the driver to place the concrete right where the crew wants it, and front-driving axle helps get it through sand and mud. Here the chute is stowed for travel, with its extensions flipped up.

By Tom Berg

Precise concrete placement is a traditional feature for this front-discharge mixer, but relatively new is natural gas power.

Test Drive: Cummins-Eaton Powertrain Smooth as Silk

The brand-new Peterbilt Model 579 loaned to us by TransX Ltd. had less than 40 miles on the clock. The SmartAdvantage powertrain makes it a very nice place to work.  Photo: Jim Park

By Jim Park

Cummins and Eaton may have finally nailed it with their SmartAdvantage Powertrain combo, reports Equipment Editor Jim Park in July's Test Drive. The SmartAdvantage powertrain offers fuel and weight saving, as well as a very, very good driving experience.

Test Drive: Detroit’s Smooth Self-Shifter

This Freightliner Cascadia Evolution is equipped with a Detroit DD13 diesel and smooth DT12 automated mechanical transmission. The van shown here was empty, so we swapped it out  for a heavily loaded flatbed trailer for our evaluation.

By Tom Berg

“Proprietary” is a magic word among truck builders. It describes components of the company’s own manufacture or design that are installed on the company’s own trucks. For truck users, this can be a good thing, because they’re designed to work specifically with a company’s other components.

Test Drive: Natural Gas Freightliner Cascadia 113

By Jim Park

Freightliner’s Cascadia 113 and the ISX12 G from Cummins Westport aren’t exactly strangers. About 100 of the trucks have been in customer hands for some months now. Equipment Editor Jim Park takes one for a spin.
