Is it possible with one pedal driving on e-tron #56

Question: Is it possible with one-pedal driving on e-tron?

Background: Many less advanced EVs support one pedal driving meaning that when you lift the foot from the accelorator (gas pedal) it will actively reduce the speed using regeneration. In this way, you never need to use the brake pedal (you can if it is an emergency). That is the reason they call it "one-pedal-driving"

Answer: Audi has not made it possible to enable one pedal driving permanent. They rather want their drivers to maximize the effiency with coasting instead of automatic reducing speed when you lift the foot of the gas pedal. One pedal driving is less efficient since you loose energy compared to coasting. This is because you only get approx 80% of the kinetic energy the moving car has, back to the battery, when doing recuperation. (Assuming the traffic and road allow to coast) You is also forced to have the foot on the pedal at a specific position to freeroll/coast to find the position when no energy is going out of the battery and nothing is going in.

On Audi e-tron can set recuperation to manual (MMI -> Vehicle -> Effiency Assistant -> Recupration) and then you can every time you start a drive, set recuperation to the max with the steering wheel recuperation paddels, and then it will regenerate every time you lift your foot of the "gas pedal" and works as "one-pedal-driving".

With the whel paddles you can set the recuperation to 3 different levels. (for more or less braking). High, medium and off. This is the left paddle to increase regen. bilde

Right paddle to reduce regen.. bilde

This shows how the regen is on 50% on max. bilde

This is not recommended for experienced drivers. If you learn to coast you will get the best comfort and the best range. Next time it will be reset back. For drivers coming from other EV's, this might be the way to unlearn the bad habit.

If you set it recuperation to automatic it will only recuperate when you are getting close to others cars or you are close to a intersection or other reasons you need to slow down. Otherwise it will coast and save the maximum amount of energy as long you don't press the accelerator.

This write-up is nice, but I wholeheartedly disagree with the notion that it shouldn't be a feature. I disagree also with the statement that for best results one should coast. That assumes that electric efficiency is the utmost and primary goal. If indeed that is the goal, then Audi should also remove sport mode, and normal drive mode, and leave us just with eco mode, because after all that is the most efficient. Further, we can get rid of all the air suspension options, too. Simply have it set to automatic.

Obviously I'm being facetious. One pedal driving is clearly a user preference, and one that should be supported and respected. All of the modern EVs do in fact provide one pedal drive modes nowadays, and even Tesla retrofitted the feature for those cars which had the appropriate drive motors to handle it.

I hope Audi adds true one pedal driving.

This is the 2nd time I passed on buying an Audi since they don't offer automatic 1 pedal driving. They current approach of setting it up manually each time is too annoying. I owned 4 Tesla since 2011 and every car that doesn't offer 1 pedal driving looses me as a customer. (Lexus, Audi, etc...). But Polestar, Tesla, etc... are now my only choices.
