We’ve been devoting so significantly aim and electrical power (pun supposed) on truck manufacturers’ race to provide electrical pickups to current market, we thoroughly failed to note that EV Course 8 large rigs are really on the street now, in confined, serious-entire world exam environments in California and the Pacific Northwest.
Freightliner of Portland, Oregon, (a division of Daimler Trucks North The usa) is just one of the providers at the forefront of electrifying professional rigs, with its eM2–a Class 6 and 7 box/”straight-career”-sort truck for choose-up and shipping and delivery apps (up to 230-mile vary), and Cascadia–the flagship of Freightliner’s eMobility program–a Course 8, tandem-axle beast at present made for community and regional distribution of dry items (250-mile vary).
The vehicles are established up to operate as day-trip deliverers that return to base for an “eFill” right away recharge.

Equally rigs are slated to start out creation in 2022. When introduced, they could perhaps transform the trucking recreation, as 100 p.c electric electrical power dramatically lowers prices to have and run, and actually eliminates their exhaust emissions. Both the eM2 and eCascadia are also considerably quieter (conserve for 12-volt cooling lovers that occasionally cycle when vans “idle”) than diesel-driven vans.
On Wednesday, May possibly 20, 2021, Freightliner officers afforded us an prospect to pilot each rigs and get a firsthand appear at and really feel for electrified trucking. We also had a prospect to jockey the Saf-T-Liner C2 “Jouley,” a Thomas Created Bus Firm university bus that’s also moved by batteries (134-mile cost array).

The vehicles have been making rounds amoung point of view purchasers, who give engineers feedback and solutions for modifications and/or advancements in the production vehicles. The generate possibilities also permit testers to produce best methods for applying EV rigs into fleets, and so forth.
Driving the eCascadia
As a common tractor, the 2022 Freightliner eCascadia is not a great deal distinctive from its diesel-powered sibling (which just occurs to be North America’s very best-providing Course 8 platform), save for its 315- to 475-kWh batteries (usable potential) which experience underneath and across the width of the taxi, digital instrument panel highlighting battery usage and reserve, and pairs of electric motors that are affixed to each and every rear axle.
Lights, electrical power steering and other accessories operate with 12-volt ability, and slowing and halting is managed by air brakes that are assisted by a slick, tri-degree regenerative program, which capabilities in the same way to a diesel’s exhaust brake, but also regenerates the truck’s electric power offer.
eCascadia’s 82,000-pound GCWR requires operators to have a industrial driver’s license (CDL) in get to generate it as a tractor/trailer combination. Although our check was relegated to a closed parking-large amount course at Dignity Well being Sports Intricate in Carson, California, we had been able to practical experience electric power’s smoothness and quick acceleration in a huge rig, which in fact is very equivalent to the takeoff and powerband of Teslas and other eSedans. Our whole load was close to 60,000 kilos, which 2022 Freightliner eCascadia dealt with with overall relieve.
Of training course, in addition to the truck’s effectiveness, it can be unattainable to disregard the simple fact that the 2022 Freightliner eCascadia makes just about no seem, other than for a slight “whirrrrrrrrr” of the motors as the accelerator is frustrated, and “pshhhhh” from air brakes when halting.
As these points go, we’re now at a place the place calling electric vans “the potential” is not accurate. They are happening now, on tiny and massive scales. For rigs like Freightliner’s new eM2 and eCascadia, accomplishment seriously is contingent on the availability of eFill recharging devices (absent from a truck’s stage of origin in the occasion it cannot get back again), and increasing the trucks’ vary to facilitate hauling higher distances.
