TESTED: SPEED IMPACTS RANGE - BUT BY HOW MUCH? TESTING RIVIAN R1T AT 60MPH, 70MPH AND 80MPH

EV Channels Review

This video thoroughly tests the range impact of varying speeds on the Rivian R1T, comparing efficiency at 60, 70, and 80 mph. The reviewer, Branden Flasch, found that while slower speeds yield better efficiency, the difference might be less significant than commonly believed. At 60 mph, the R1T achieved approximately 2.62 miles/kWh, dropping to 2.25 miles/kWh at 70 mph, and further to 2.02 miles/kWh at 80 mph. Despite the lower efficiency at higher speeds, Flasch concludes that the trade-off might be worthwhile for overall trip time, especially with robust fast-charging infrastructure. He prefers faster driving and more frequent, albeit potentially longer, charging sessions to minimize total travel time. The reviewer also notes that the all-terrain tires may be a significant factor in the tested efficiency.
