Apparently, Porche agrees with me: Porsche's Approach To Regenerative Braking - CleanTechnica Producers of electric cars are mostly focusing on one-pedal driving. By simply taking your foot off the pedal, you can immediately start regenerating energy and in some cases experience such extreme braking that the brake lights will come on automatically. This means that most scenarios allow drivers to operate their car with only one pedal. By contrast, Porsche utilizes coasting: a smoother method of allowing the vehicle to travel forward with no external power. The recuperation process only begins when you apply pressure on the brake pedal. “This is a more efficient way of driving, because it keeps the kinetic energy in the vehicle,” says Reichenecker. One-pedal driving, on the other hand, recuperates first, and only then converts the recovered energy back into propulsion. “That results in twice the losses.”
Then buy a Porsche. “This is a more efficient way of driving, because it keeps the kinetic energy in the vehicle,” says Reichenecker. One-pedal driving, on the other hand, recuperates first, and only then converts the recovered energy back into propulsion. “That results in twice the losses.” This ignores that one pedal has a free coast segment between acceleration and deceleration on the pedal. My gen2 Prius had that. There is a safety concern with free coasting when foot of pedal. It means a moment of no deceleration when in an emergency situation before brakes are applied.
Braking, accelerator, and steering feel varies between models too. Don't like it, don't buy it. How do we inform the deer?
Is the 'no free wheeling' bit still in the vehicle code? I know it's in there because early brakes were primitive, and needed engine braking for help, but free wheeling is literally what foot off pedal no deceleration coasting is. It is partly the reason why the Prius has mild braking when off pedal.
No, Porsche focuses on performance, not efficiency. Their Taycan, for example, is rated at 89mpge. https://www.fueleconomy.gov/feg/Find.do?action=sbs&id=46025&id=45756&id=46206 That puts any gas car to shame, but lags way behind with EVs.
And for at least the last 25 years their ICE sports cars have required premium gas with its attendant upcharge. Like those who buy Porsches care.
From the range tests done with the Taycan, the EPA tests may not be showing the car's potential though. For the more performance models, the engines are designed for octanes higher than available at a US pump.
Here are my options: My practice is to drive in this mode but IF leaving a divided highway for a long access road, I lift the gear selector to the first stop which puts the car in "N" for coasting. This is the same method I used with our Prius. Bob Wilson
I understand it is the same as "N" but I have no interest in using it. Defeating regenerative braking leads to higher brake pad wear and loss of energy by heating the brake pads. I'm too cheap frugal to use it except in special cases. Even then my hand remains on the shifter stalk to turn it on as needed approaching a stop light or sign. Bob Wilson
So it disables one pedal driving, and goes into coast with foot off pedal. Or is it just the behavior of of the car at low speeds, or after a stop, with foot off pedals?
