Not sure where
Kelly Blue Book got this information, but...
"In the Mach-E, when you need a bit more deceleration (say, for an upcoming red light), you can press the L button in the center of rotary shifter to engage low range and slow the electric Mustang SUV a bit more without touching the brake pedal. Low range, for the record, is available in all three drive modes, but it doesn’t provide any more regen braking than what’s already tuned into the Unbridled mode."
Also from
The Detroit News:
“
One-pedal driving. All electric cars use electric motors for regenerative braking to recharge the battery. Regeneration enables one-pedal driving – that is, lifting your foot off the accelerator slows the car. Want more aggressive regeneration? You can dial in more resistance in the Mach-E by pushing the a button in the middle of the rotary console shifter."
