With the right maintenance strategy
emphasizing fuel efficiency, a fleet can
have it all: better fuel economy, more
uptime, and lower maintenance costs.
By John Hitch
[ EMISSIONS & EFFICIENCY ]
The North American
Council for Freight Efficiency
identified several areas that can
impact fuel efficiency, releasing a vast
library of confidence reports and guidance on
crucial areas ranging from the powertrain and
low-viscosity engine oils to low rolling resistance
tires and aero kits. The 2019 Annual Fuel
Study detailed how using a wide swath of available
fuel-efficiency technologies affected the 21
participating fleets' fuel costs. The 73,844 trucks
involved " saved $895,318,953 in 2018 compared
to the average trucks on the road, " according to
the report. Collectively, these trucks averaged
7.27 mpg; the national average for the previous
year was 5.98 mpg.
It's a major reason OEMs have eschewed their
classic tough-guy exterior look for sleeker bodies.
Just look at Kenworth and Peterbilt trucks. The
Paccar-owned
truck makers
both launched updated
versions of their flagship OTR
haulers in early 2021. With additions
such as the updated Paccar integrated
powertrain over the 2017 MX-13, larger air
dams, and narrower hood, the Peterbilt Model
579 betters its predecessor's fuel efficiency by 7%.
For the T680 Next Gen, Kenworth added a new
aero bumper and hood, lower fairing extensions,
28-inch side extenders (and more), which can lead
