Silverado EV highway range at 120 km/h
NRCan's tests show the WT Max Range using 23% more energy on the highway than in the city, so highway range is lower the combined rating. NRCan's highway cycle averages well under 100 km/h, so we take its highway figure and reduce it by 15% for 120 km/h. The Silverado EV ranks #1 of 30 on this estimate.

Silverado EV real-world range
Real-world range depends on speed, temperature, wheels and load. Mixed driving in mild weather usually lands near the rated 793 km. Sustained highway speeds pull it toward the 603 km estimate, and a cold highway trip can drop it further; see the Silverado EV winter range. For trip planning, most drivers use between 10% and 80% (charging stops) or 100% (leaving home) of the battery, which is about 447 to 575 km of highway driving.
