The Downspeeding Learning Curve

Rolling two-lane roads are no place for a downsped driveline. If you’re considering a downspeeding axle spec, application and terrain must be considered. Photo: Jim Park

By Jim Park

Today's "downsped" drivetrains can improve fuel economy, but high torque and low axle ratios can create all sorts of havoc with drivetrain components.

How Tires Affect Fuel Economy Testing

Apples to oranges. Accurate fuel economy test results can only be obtained using idendical trucks, including the tires.

By Jim Park

When setting out to evaluate a fuel-saving product, you don't want your numbers skewed by differences in rolling resistance from the tires. With some fuel-saving devices promising only marginal gains, the tires' contribution to the fuel consumption can adversely affect the apparent performance of the product. Here's what to watch for when setting up an evaluation or testing program.

Inflate your Tires, Not Your Fuel Bill

The harm from overinflating tires, especially those that run a high percentage of unloaded miles, could outweigh the perceived gains in fuel efficiency.

For as hard as fleets work for a 1% gain in fuel efficiency, it's hard to imagine giving up something like 2-4% in fuel efficiency to something as simple as maintaining correct inflation pressure, especially today when almost every inflation or monitoring system on the market offers payback in less than a year.
