ELECTRIFICATION FEATURE
" We believe lastmile
delivery will be
the first segment to
successfully
transition [to EVs]. "

bars on this vehicle. What enables that
is this wide frame rail. So, we get that
high primary roll stiffness with the wider
spring spacing, but don't have to
sacrifice ride comfort as a result. "
There also is no shackle on the rear
leaf spring. Shiffler explained that this is
a patented design by Hendrickson that
also helps maintain ride-and-handling
balance based on load. " That's the
magic of how the variable-rate curve
works, " he said. " It actually over-constrains
the spring. So as the spring deflects,
it builds rate because it's pulling
in on the frame brackets by design. "
Shyft senior VP and general manager
Eric Fisher outlined the thermal-management
system of the Blue Arc van.
" There's multiple valves that divert the
antifreeze to the heaters, the compressor
or into the loop to the front radiator, "
Fisher said. " They're isolated but
they're not isolated. The drivetrain can
generate a lot of heat, so we take that
energy and use it to heat the cabin.
We're always sharing some of that energy
from the truck to increase its performance.
It's all about optimization
and trying to make sure that you maintain
and reduce the energy use. "
Fisher also detailed aspects of the
Blue Arc van's automotive-grade composite
body, which reportedly was designed
to be as modular and flexible as
possible for the various body lengths
Shyft intends to offer. Fisher pointed
out that the body alone represented an
estimated 20% weight reduction compared
to a non-composite-bodied van.
The model that was used as a demonstrator
tips the scales at roughly 9,000
lb. (4,082 kg). This body has been in
production for three years on other
Shyft products.

We were too.
That's why we invented
the wave spring.
* Optimize Application Space & Weight
* Industry-Specialized Design Support
* Large Selection from Stock
* Easy to Customize
On the track
TOHE piloted the Blue Arc van for a lap
around the test track at M1 Concourse.
While the demo unit still was not production-ready,
it was apparent from
behind the wheel and looking under the
skin that this was far from an engineering
mule with a hastily fastened body.
TOHE also has toured Shyft's engineering
facility in Plymouth, Michigan, where
Adams and Fisher provided a detailed
