Adding 100 miles of range in 17-18 minutes and 150 miles in 30 minutes isn’t class-leading, but it’s fast enough for most potential Mach-E owners, considering the majority of owners won’t even need to DC fast charge more than once or twice a month.
Living in a winter climate for 3 or so months out of the year a 30 minute fast charge in winter conditions isn't going to provide a 150 mile range.
