A new test by CAA in Canada has determined that electric vehicles (EVs) lose 14 to 39 per cent of their range depending on the model of car.
In a test, the roadside assistance company took a fleet of EVs from Ottawa, Ont., to Tremblant, Que. This route didn’t fully deplete the cars, but once they got to Tremblant, each car looped through the mountains until it reached zero per cent battery.
The Chevrolet Silverado came out on top with a maximum cold-weather range of 456km, which is 32 per cent below its quoted average range of 724km. That said, the Polestar 2 hit 384km of range, which was only 14 per cent lower than its estimated range of 444km. This was the smallest gap of the entire competition.
The worst offenders were the Toyota bZ4X, which lost 37 per cent of its range, dropping down to 255km, and the Volvo XC40 Recharge, which dropped down 39 per cent to 248km.
The company also did a quick 15-minute DC fast charge on each vehicle to see how much range a short charge would supply. The Tesla Model 3 gained 200km, the most of the group. The Silverado and Equinox EVS from Chevy came in second and third, adding 199km and 131km, respectively. The worst was the Toyota again, which only added 19km.
Overall, this is a great resource, and it’s fantastic to see more research being put into cold-weather EV performance. While we’ve known for a while that cold weather will limit EV range, it is nice to see that some manufacturers seem to have found more ways around it. As ranges increase, this also becomes a less significant problem.
