Truck & Off-Highway Engineering - April 2024 - 29

ORIGINAL EQUIPMENT
The Mack MD Electric is produced at the same
factory as its ICE-powered counterpart.
Mack displayed the production version of the
MD Electric at NTEA's Work Truck Week in Indianapolis.
at Mack Trucks, on the show floor at
Work Truck Week and discussed some
of the design details of the MD Electric
as well as overall customer reception to
the truck's performance.
" The first thing they tend to notice is
how quiet the truck is, " Barraclough
said. " The other aspect our customers
love is the performance off the line.
There's no waiting for the torque converter
to catch up or the turbo to spool.
You just hit the pedal and you're off.
Our customers really love that. "
Barraclough also discussed the development
process from prototype to
production and some of the unique
features of the MD Electric. " We really
didn't have many major changes from
prototype to production, " he said.
" Mostly tweaking the regen and how
that performs and other minor software
changes. "
Barraclough pointed out the E-PTO
TRUCK & OFF-HIGHWAY ENGINEERING
as one of the most important features
of the MD Electric. " The E-PTO is a necessity
for trucks like these and is very
important to our customers, " he said.
" We needed to provide that capability
so that they could run smaller hydraulic
devices. It's a little different concept
than a PTO on a combustion truck because
that will mount to the transmission,
which obviously we do not have
on a battery-electric truck. "
Barraclough also affirmed Mack's decision
to outsource the powertrain of the
MD Electric. " We have our own in-house
solution powering our LR Electric (www.
sae.org/news/2021/12/mack-begins-production-of-lr-electric-truck),
but this is a
different animal, " he stressed. " We felt
that this system was a better fit and offered
a turnkey solution that would allow
faster time to market with a proven powertrain
solution. "
