  • and brake wear have become such a significant proportion of emissions

    As a conscious "experiment" I monitored how much I used the foot brake vs regenerative "braking" during a 61 mile journey the other day. Mixture of dense urban, countryside and motorway road use:

    I used the foot / caliper brakes precisely once during the outing: whilst I was reverse parking on returning to my house.

    So, from a brake dust perspective, EVs do seem to be almost infinitely better.

  • Is the foot brake not regenerative braking? My hybrid seems to indicate charging when I brake.

  • It's the momentum of the car that generates the power so foot braking or not, while you're slowing, it'll be generating some back but you'll slow quicker with the brake on and generate less power

    I assume, IANAE(ngineer)

  • Depends on the car I think. I’m sure some of them activate regen via the brake pedal or use friction braking when in one pedal mode.

  • Yeah it is, to an extent.

    On my Niro, the foot pedal will operate regen braking to begin with, but will operate the disc caliper if more retardation is needed.

    My observation was that I didn't put my foot on the pedal until the very end of my journey.

    It definitely doesn't use the disc calipers (friction brake) unless I press the pedal, or if it invokes a safety stop, in response to a collision detection or fast deceleration in adaptive cruise control mode.
