One-pedal driving

[daveo4EV]

OPD is only here because Tesla could never get the blended braking seamless and so it made a generation of people who think it’s the best thing since sliced bread but in reality 95% of the world coasts and brakes, we have 4 cars and they all brake and coast in the same manner (yes you can drive the iX OPD in B mode but nobody in the family uses it)

I understand and agree with your point - but I find Tesla's system a bit more "honest" - let me explain...

in terms of driver control I know for a fact that there is no friction braking involved on a Tesla unless I as the driver touch the brake pedal - it's a very 1 to 1 mechanical relationship - and I can adjust the amount of regen from lifting off the accelerator - so I as a driver control the amount of regen and then can blend in the friction brakes 100% under my control…

with "blended" braking I only control deceleration, but not the "mix" of regen and friction braking - in fact when you start out with Taycan in the morning it's all friction braking, and then later in the day after things warm up you get a 'mix' - so it's constantly changing since it's under control of the computer as to how much friction braking you're getting and how much regen you're getting

I'm not saying one system is better/worse - but one system is certainly more under the driver's control - and it's not the Porsche system - because it's entirely a software illusion as to the mix of regen and friction and the driver has no control over the exact blend of how the deceleration is accomplished…

Oh, and yes, OPD does active the braking lights, for all cars I think.

Hey, if the EU can regulate your bloody bottle cap to stay tethered to your bottle I am sure they regulated the hell out of this one too.

PS. Hoping not to start another thread on EU regulations

But this is not "OPD" so I still don't know about brake lights. Haven't had a friend tail me to see yet.

It does, if the car brakes on the engine with OPD beyond a certain level it turns on the brake lights.

correct - brakes lights on EV's w/regen are activated by accelerometers that turn on the brake lights at some specific g-level of deceleration…brake lights are no longer purely controlled by a on/off switch of the brake pedal.

Porsche's implementation of mild one pedal (emulating engine breaking) appears to be perfect to me and for spirited driving. You can choose to coast instead to extend range.

I've been one pedal driving a EV for 5 years now, kinda like it around town or low speed. But it takes co much attention to drive back roads or highways smoothly. Its hard to precisely control braking/acceleration when driving with some enthusiasm. I wouldn't expect anyone that drives with enthusiasm (e.g.Porsche fans) to be happy with one pedal.

We also have learned much since marketing thrust one pedal onto an unaware public years ago. It was touted as, and felt like, you were saving electons and extending range, where, in fact, it hurts range or efficiency. Its become just a novelty that marketeers can have fun with. I've stopped using it unless I'm playing the game of timing stops at stop lights.

IMHO, with all the software bugs Porsche has with these cars, they should be fixing the bugs and not spend any effort developing a Porsche worthy implementation of aggressive one pedal.
