70 MPH VERSION OF THE OUT OF SPEC "10% CHALLENGE" WITH MY STANDARD RANGE AWD MACH-E

EV Channels Review

This video details a "10% Challenge" test on a 2022 Ford Mustang Mach-E Premium Standard Range AWD, focusing on a 70 mph highway speed. The reviewer highlights that this specific model, equipped with the NCM battery, has a lower peak charging speed (115 kW) compared to newer LFP models. The test involved charging for 15 minutes from a 10% state of charge and then driving at a constant 70 mph. The vehicle achieved 64.5 miles before hitting 10% charge, with a final range of 73.6 miles upon returning to the charger with 7% remaining. The reviewer notes that while this is 10 miles further than the previous 80 mph test (approx. 55 miles), the cooler ambient temperature (63°F vs. high 80s/low 90s) also contributed to better efficiency. The video contrasts this with the estimated performance of LFP battery models, suggesting they could achieve 65-85 miles in the same test conditions. Overall, the reviewer finds the results reasonable for the specific configuration and conditions, emphasizing the impact of battery type, speed, and temperature on EV range.
