Try this small experiment: (do this on a quiet street with no traffic).

With the display showing the energy transfers...

While gliding (no energy transfer to/from the battery), press the brake pedal (with your left foot).

You will note that you will slow down faster, but no energy is recovered.

This proves (to a point) that there is no regeneration caused by the brakes in the Synergy Drive System.

Regeneration occurs when you lift your foot off the 'go' pedal. (It's not a gas pedal anymore, nor an accelerator pedal, but it does make you 'go'!).
