coasting

Please note there is a difference between the two. Freewheeling is simply moving without being "geared", that is, you can put the car in Neutral, and let it go down the hill, for example. Coasting, in the other hand, implies there was traction/impelling before and only then the transmission was put in neutral, therefore, runnin in inertia or "Girando por inércia" and not "em ponto-morto".

Hi Mauro. Thank you for your comments. My reference to the legality of riding with a manual-shift or automatic non-electric car in neutral was simply to point out that it does not appear to fit the asker's context, a context where shifting is properly left to the onboard computer, and where 'coasting' is part of ordinary driving. Thanks.

also happens in a drive/stop situation, when approaching traffic lights, for example,to save gas, and not just driving down hills

Disadvantage of coasting

My experiences in Dallas with an electric car.


Disadvantage of coasting:

Earlier, we discussed what regenerative braking is, so I won’t cover that any further. Coasting? Well, that should be fairly clear. It is shifting the car into neutral while the car is moving.

You have to shift the vehicle into NEUTRAL. In emergency situations, you could not accelerate out of harm’s way without shifting back into a DRIVING mode.
Doesn’t work well in stop-and-go traffic situations.

Dear Tobias, thanks for solving the mystery of this pleonasm. In German apparently the two verbs denote quite different things.Now as for your comment on coasting being illegal and dangerous: not in an electric car. In an electric, when coasting downhill, as I mentioned in my answer, the electric motor goes automatically into a electromagnetic brake mode: as the stator windings are excited, the motor becomes a generator, sending current to the battery and braking the car , as the generator demands mechanical energy to work.

I think 'coasting' here simply refers to riding without your foot on the gas (e.g., going down a hill, as helpfully pointed out by Mauro.) Why would the text be making a reference to a style of driving which is in fact illegal in many places?

Source may be a translation from German, which might explain the redundant 'coasting or freewheeling'.

Das Bremssystem eines Elektroautos ist so konstruiert, dass die Energie, die beim Bremsen, im Schubbetrieb oder beim Ausrollen frei wird, zurück gewonnen und in den Akku rückgespeist wird (Energierekuperation).

"coasting" e "freewheeling" são sinónimos...
