Any on-highway truck you spec today will likely employ downspeeding to some degree. Engine downspeeding is enabled through faster axle ratios that allow the engine to maintain a lower RPM—thus saving fuel—while still providing the necessary power to the axle. Axle ratio is written as a ratio, such as 2.16:1. But what does 2.16:1 mean?
Remember that most modern powertrains utilize some degree of downspeeding. Here’s a quick refresher on downspeeding details.
If the engine is the heart of your powertrain and the transmission is the shifting brains behind the operation, then the axle is the muscle, propelling your truck down the highway. While the engine and transmission get much of the spotlight, the axle plays a key role in increasing efficiency—in both proprietary powertrains and those
Axle vents are something few people ever think about, but they play an important role in keeping the axle in operating condition. Axles generate a lot of heat running down the road. As the axle increases in temperature, the air pressure inside the axle likewise increases. To accommodate the increase in air pressure resulting from
The Kenworth T270 and T370 are now available with the Dana Spicer S140 series of single-reduction, single-drive axles, ranging from 16,000-lb. to 21,000-lb. gross axle weight rating. According to Dana, the four S140 series axles are designed to handle a wide range of applications and feature broad ratio coverage from 3.31 to 6.50, allowing maximum
Electrification is the story of the year in the trucking world. From Cummins to Fuso to Chanje to Tesla, serious moves were made by various OEMs to begin the process of bringing what was previously a theoretical concept to the real world. No one can deny that electrification is coming. With new priorities for OEMs

Any on-highway truck you spec today will likely employ downspeeding to some degree. The sources within this story all agree that the majority of trucks today are putting faster ratios on the road. It’s a trend being driven by increased powertrain innovation and integration, with automated manual and automatic transmissions playing a key role in
While adoption of 6×2 axle configurations in over-the-road applications has lagged behind industry expectations—largely because of unexpected challenges and consequences in making the switch to 6×2 configurations, as well as lower-than-expected fuel prices making such a switch less of a money saver—there is still significant interest among fleets in making such a switch. And those
