Gaston Töpfer, a long-haul driver with Erb Transport, has plans to run a half marathon. On its own, that may not sound terribly impressive. It’s pretty amazing if you know that not so many months ago, Töpfer was having trouble playing with his kids for more than a few minutes due to his weight.

Did you hear about the driver who backed into the transformer for a huge regional mall, shutting it down for a Saturday during the Christmas shopping season?

When we’re talking about on-highway trucks, there are opportunities in aerodynamics, low-rolling-resistance tires, “downspeeding” and other strategies to save fuel.
But when you’re talking delivery trucks, work trucks, vans and the like, the strategies are different. Below are four approaches to improving mpg for mediums.

Trucking operations generally don’t invest in technology with the sole purpose of becoming “greener.” For most fleets, the decision is prompted by a desire to improve operational efficiencies, customer service and the bottom line.

Traditional thinking on automated manual transmissions has it that AMTs are the great equalizers – bridgers of skill gaps between the best and the worst drivers in the fleet. While that’s still true, AMTs now bring even more to the fuel-economy table, offering fuel savings in their own right beyond what even the most professionally driven manual transmission could accomplish.

Royal Jones, president and CEO of Mesilla Valley Transportation, is known for his near-obsessive attention to saving fuel. Yet eight or nine years ago, the fleet was averaging nearly 50% idle time.
There aren’t many things less aerodynamic than a box. And a dry van trailer is basically a 53-foot box on wheels. The drag caused by that box and its effect on fuel economy is a challenge that has been taken up by the SuperTruck program.
In 2007, as many truck and engine makers started announcing they would use selective catalytic reduction to meet 2010 federal emissions regulations a new term entered our trucking dictionary: diesel exhaust fluid.
As we soon learned, SCR is an aftertreatment technology that injects small amounts of DEF, a water-based solution containing urea, into an engine’s hot exhaust stream to reduce emissions of nitrogen oxides (NOx).

Pilot, the largest truckstop chain in the country with more than 650 outlets and $29 billion in annual revenues, is being investigated for allegedly defrauding customers by withholding fuel rebates and discounts.
You get 30% less tread on some fuel-efficient tires, they cost 15% less up front and they run fewer miles to take-off, but does the money saved on fuel because of the lower rolling resistance make up for the shorter overall life?
Many fleets are struggling with that question today. The answer is often anything but clear.

How does 18 mpg in city driving and 25 on the highway sound for a full-size pickup? That’s what Chrysler’s Ram brand is claiming for some of its 1500 series trucks with a gutsy V-6 gasoline engine mated to an 8-speed automatic transmission.
