Coasting or Regenerative Braking on the Motorway: Time to settle the matter!

Once again we search for pseudo scientific evidence of the value of coasting which should turn all of the energy into motion, rather than being partly lost in the transfers through regenerative braking.

Let's see if we can conclude based on this experiment.

Also coasting is a 'state of mind' as it pushes your senses to more defensive driving. Knowledge of the route also helps as you can coast more on a downhill exit etc.
I found the difference on my Ioniq Classic during a couples of weeks 'normal' driving (regen 2-3) and coasting to be an increase from 250km to 260km as reported maximum range.
So for me the 10km additional range was little and would not contribute that much for the small battery (28kWh). Maybe a car with a bigger battery would have more difference as understandably you have a longer timeframe to eek more miles/km during use.

A blend of both seems the wisest approach and the one to likely give the most efficient results to be honest.

A lot of motorway driving in the UK is stop-start, or at least involves constant speeding-up and slowing-down. The advantage for the driver of regen mode is that it's easier to respond to speed changes without needing to use the friction brakes too much. However, the disadvantage for fossil drivers behind is that they don't understand why your brakes lights are coming on so frequently. As we are still living in the dark ages of cars powered by decomposed sea creatures, it could be a slight safety issue if brake lights are distracting to the car behind? Or maybe it's worse when the brake lights don't come on as frequently? Discuss...

This video has a big mistake. You need to do both tests starting from the same state of charge, the % of energy in the ioniq is not linear and 10% going from 90% to 80% is a lot more energy than from 30% to 20% for example. Try and do a similar test to the one in the video but this time start both at 90% or 95% charge and you will see different results 👍🏼😊

Coast as much as possible
Regen on big downhill sections
