Direct Drive or Overdrive?
The long-running debate over which type of transmission — direct drive or overdrive — provides the greatest efficiency is one that’s not easily settled and not likely to go away.

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.
Combine a truck crash, a celebrity, and an election year, and what do you get? An HOS rules feeding frenzy on Capitol Hill and in the media.
Is lightweighting actually new? Well, not really, at least not in our world of big trucks and long trailers, says Rolf Lockwood in July's "Locking It In" column.
Few things will impact your overall recruiting, driver qualification, and safety results more than the quality of new drivers you bring into the organization.
Fleets should prepare for and practice what to do in the event of a serious accident just like they do for fire drills — from top management to dispatchers to drivers.
There's little doubt left that tires formulated for lower rolling resistance work as advertised, but it's still tough to give up at few thousandths of an inch of tread. After all, tire miles are important, too. How much of a difference does the reduction in rolling resistance make?
A bulk fuel tank in your own yard could be the most cost-effective fleet fueling option -- assuming your tank doesn't "leak."
After finding the "old Pete" in an Arizona desert in the mid-1990s, restorer Bob Dean decided to give this classic 1939 Peterbilt a new life just in time for the company's 75th anniversary.
A sampling of the products trailer manufacturers have newly developed and made modifications to, as well as recently announced partnerships and expanded production capabilities.
While warmer temperatures help to increase battery capacity, making it easier to turn over the engine, they also cause an increase in the rate at which the battery deteriorates. When the temperature is warmer, the current conducting grids corrode faster, reducing the life of your battery.
While drum brakes have been enlarged and strengthened to meet stricter federal stopping distance requirements and are currently used on 90% of heavy trucks, discs are gaining in popularity.
Trucks are on the road much longer than they used to be, and that translates into a greater demand and investment in parts, service, and ongoing maintenance. Which means parts purchasing decisions more important than ever.
To meet expected greenhouse gas/fuel efficiency standards, oil companies and engine makers have been busy developing a new standard for engine oils that will provide a new type of lower-viscosity oil to improve engine efficiency.
With regulations affecting how fleets fit their wheels, the retreading industry is still deciding whether or not the inclusion of verified low-rolling-resistance tires on the EPA's SmartWay list has helped the industry.
