Peterbilt Unveils Model 220EV at CES

The 220EV joins the previously announced Model 520EV and the Model 579EV in the Peterbilt
electric vehicle lineup. In all, Peterbilt will have more than 30 electric vehicles in operation by
the end of 2019 with customers representing the refuse, regional haul, and city delivery applications.

“Peterbilt has been at the forefront of truck electrification, and adding the medium duty platform to our electric truck line-up was a natural evolution of our development plan. We will now have trucks in the three applications where electric powertrains may have a return on investment for
our customers.” said Peterbilt General Manager Jason Skoog. “Today, we have Model 520EV’s
and Model 579EV’s on the road with customers, experiencing real-world environments and
performing well. In addition to the customer field trials, Peterbilt is engaged in validation testing
at the PACCAR Technical Center (PTC) in Mount Vernon, Washington. Data collected during
customer trials and testing at PTC will be used to ensure that Peterbilt EV’s meet the same
rigorous standards as our current trucks.”

The zero emission 220EV is powered by two TransPower battery packs with a total of 148 kWh
and a Meritor Blue Horizon two speed drive eAxle. It features a range of 100 miles and a
recharge time of one hour when using a DC fast charging system, making it an ideal option for
local pick-up and delivery operations, while still providing the premium performance and driver
experience customers expect from Peterbilt.

Added Skoog, “Just like any Peterbilt, an electric version will be the Class of the industry,
delivering a durable and reliable truck with low total cost of ownership to truck owners,
combined with the premium experience truck drivers expect from a Peterbilt.”

Peterbilt will begin delivering the 220EV in the summer of 2019 and will put a total of six in to
service this year with a major customer.
