Does this advice apply to all cars?

It’s worth noting that even with hybrids and battery-powered EVs you will generally get better efficiency if you brake gradually and accelerate slowly.
When you brake in one of these cars it will use some of the energy to charge the battery back up, and some of it gets lost as heat. The harder you brake the more energy gets lost as heat.
Similarly, the faster you accelerate the more power is needed. In a hybrid this might cause the gas engine to kick in earlier and rev higher, which reduces efficiency. In a battery-powered EV more power means more current, which means more energy wasted as heat.
Battery-powered EVs don’t lose as much efficiency when accelerating quickly, but there is still *some* impact.
