HUMMER EV COLD WEATHER EFFICIENCY AT 60, 70, & 80 MPH

EV Channels Review

This video details an efficiency test of the GMC Hummer EV in cold weather conditions, specifically at 60, 70, and 80 mph. The reviewer, Kyle, conducted the tests at temperatures ranging from 16°F down to 10°F, with the vehicle's battery starting warm. The results showed a significant decrease in efficiency compared to warmer weather tests. At 60 mph, the Hummer EV achieved 1.4 miles per kilowatt-hour (kWh), dropping to 1.2 miles/kWh at 70 mph, and a concerning 1.0 miles/kWh at 80 mph. Despite the "thirsty beast" nature, the reviewer notes that even at 1.0 miles/kWh, the vehicle could still achieve an estimated 213 miles of range in single-digit temperatures, which he considers "not so bad." The video highlights the Hummer EV's substantial power consumption, particularly its heater, but also praises its fast charging capabilities and the overall impressive, albeit inefficient, performance in extreme cold.
