One pedal driving

The break pedal already prioritizes regenerative braking when possible, so in terms of economy there shouldn’t be a difference compared to one pedal driving.

When you brake you regenerate up to a point where the brakes themselves kick in. BYD wants their cars to feel like ICE cars, which I think is quite a shame. My Polestar 2 now does full one pedal drive and regeneration on high is quite hard braking. I'm going to miss that when I get my Seal. Though I hope they may change their mind someday and enable full one pedal driving in the future, as the MG4 got it 1 or 2 years after release as well. It's just software.

If you're concerned that not having one-pedal drive makes the car less efficient, you shouldn’t be. I’ve never run efficiency tests myself, but I’ve also never seen evidence that regeneration is weaker without one-pedal driving. The car will still recuperate energy when you press the brake pedal.

That’s the point. Bevor I’ve bought my seal, I’ve got a Tm3 with one pedal driving and I’m gonna miss this. Maybe I should get my seal in February, cause i ordered it in October.

BYD uses the Bosch blended braking system. The Tesla system of OPD is a hangover from the early days of trying to get something to market and instead of building the entire blended braking system from day one they did OPD in software. End of the day the regen braking system as implemented by BYD is setup to emulate the ICE driving experience as closely as possible as a way to remove a difference between a traditional car and a EV. Makes it easier for people like my wife who drives an ICE 99% of the time and my EV occasionally and not having to remember "the accelerator is different/funny" You can visually see any time regen is working on the dash of most BYD cars any time the power meter goes negative is when regen is operating. Assuming you have to normal/high regen switch/option in the car you have think of it more about how the car reacts to liftoff deceleration. Normal is like lifting off the pedal in a ICE car when you're cruising in top gear, the car will slowly start to slow but feel like it's effectively free rolling. High regen is more akin to dropping down a gear and then lifting off to get the engine braking effect.

I don't think it will ever show up, because of 3 main reasons. 1. Safety In a medium brake application scenario, for a traditional car, one's foot is already on the pedal and is ready to apply full braking power almost immediately, whereas in a one pedal system, where the foot might not even be completely off the accelerator, there is some time wasted to transition from one pedal to another. In fact, this is probably why China has passed a standard to essentially ban one pedal driving as the default mode by 2027(kind of like how AEB will enable itself every time the car starts, the '2 pedal mode' will also enable itself each time the car starts). 2. Efficiency BYD, since 2021, has been using a blended braking setup where both the regeneration and friction brakes are combined together, either using a Bosch module shared or more recently their own self developed module. Basically what the module does is: a) simulates a 'brake pressure' feedback when initially employing regenerative braking b) once regeneration becomes ineffective at lower speeds, automatically blends in friction braking to maintain the deceleration curve The advantage of this is that it allows a much better off pedal coasting experience since the throttle pedal is not as sensitive(since you don't have to section off one part of the accelerator for braking), while maintaining the effect of regen under braking when required. Teslas as well as some other makes of cars do not have such a controller, instead relying purely on friction braking when the brake pedal is depressed. This actually provides a more consistent braking feel, and is probably cheaper to manufacture. 3. Demographics If you look at BYD's interior design for their cars, generally the cars feel more at home with their 'traditional' ICE counterparts. For example, turn signal stalks and wiper stalks instead of on screen controls, traditional gearshift lever (either a VW style small gearshift toggle of Mercedes style column shifter), separate and centered instrument cluster instead of in screen integration, auto creep forward(very useful when parking I feel) etc. BYDs are designed to feel like a 'normal' car where the software and hardware isn't exactly designed to feel extremely futuristic, making it easier to transition from older cars. TL:DR, One pedal doesn't condition you to put your foot where it should be for instant deceleration, BYD has paid for a module and decided people should use it, BYD wants the transition from older cars to newer cars to be as smooth as possible

Having driven ev since 2012 (with 1pd) since 2015, I do find it lacking to not have it. My wife has a dolphin. (I test drive a seal excellence which I opted to not go with and stick with Tesla mostly due to 1pd) It’s very good.. but I miss the ease of use (imo) of 1pd. I do recognise that not everyone feels this way so wish cars offered both configurations

Curious why you moved from the PS2. The one pedal drive experience is fantastic

Well I have a single motor long range and feel like it's lacking a bit of power but don't want to give up range, so was looking at the dual motor facelift. They go for about 45-50k and with better packs even more. I started looking at the market what was on offer and found the BYD Seal and Tesla Model 3. Hated the Tesla but the Seal was very nice. I'd say everything is an upgrade compared to the Polestar, apart from the one pedal drive.

BYD won't implement one pedal driving. There is already an official statement why they decided to not do it. Mostly due to efficiency. One pedal mode is way less efficient than one thinks. And looking at other Chinese brands like Leapmotors I'm pretty happy BYD didn't do one pedal mode as the Leapmotors one is unusable.

I have both Tesla(y) which I leaae.and a byd(seal) company car. I prefer the 1pd of the Tesla. I also miss all the other general tech of the Tesla (and the charging infrastructure/costs!). Byd seems to want to cater for the trad car market which is fine. But it's like stepping back in time for me.

Congrats!

Lack of CarPlay makes Tesla a hard no in my case.

Short answer in my opinion, BYD probably won’t ever introduce OPD. And IMO that’s a good choice. For me it comes down to how humans actually drive, not just what’s technically possible. Pedals work best when they’re binary in your brain: right foot = go (play), left foot = stop (pause). One-pedal driving blurs that line. Now “lift a bit” means mild decel, “lift more” means strong braking, “fully off” can mean more aggressive braking. That’s fine when you’re focused and expecting it especially if it’s marketed as part of EV transition (why?), but humans get tired, distracted, stressed. Muscle memory is built around simple mappings, and the more behaviour you pack into one control, the more room there is for the brain to misfire in edge cases. This is the root reason for the proposed regulation change in China to ban full OPD (still undecided). This is analysing OPD in isolation, without even comparing to non-EVs. If BYD builds cars with both full EV and DM-i drivetrains, they have even more consistency issues to think about, but my point is: even before we go there, we should aim for clean, robust control design on pure EVs. The whole point of one-pedal is really efficiency first and then some potential convenience, not safety. It basically trains you to drive in a way that maximises regen: anticipate, lift early, avoid the friction brakes. Nothing wrong with that goal, but there are more ergonomic and safer ways to achieve so. The car can manage regen intelligently in the background (speed, gradient, following distance, nav data, etc.) and still keep the clear play/pause separation on the pedals. This is the path BYD chose. You can also coach drivers with good energy displays, scorecards, and sensible default regen levels instead of turning the accelerator into a quasi-brake. Some brands even gamify that to educate drivers. It’s primarily because of Tesla that such behavior is considered a feature whereas in my opinion i won’t want that for the reasons i explained above. Similarly i prefer not to be driven by most ppl who OPD, they sure can do better job but i get dizzy faster perhaps unless if they are experienced OPDers. In tens of efficiency, assuming regen hardware being similar in two different cars, both can achieve identical regen efficiency with and without OPD. So lack of so shouldn’t automatically translate to less efficiency. Put it together, IMO, OPD isn’t a good feature. But Tesla drivers keep asking for it, i hold we don’t make it widespread. It’s not impacting efficiency, reducing safety (in theory), to for some increase convenience. Just to be clear: I’m not saying we have crash statistics proving OPD is unsafe. What I’m saying is that from a human-factors / design point of view, it’s a less intuitive and less robust control scheme than the classic “right foot = go, left foot = stop” layout, so theoretically it carries more safety risk.

OPD is popularised by Tesla which happen to be EV. I hope it doesn’t become an EV thing as if EVs without OPD are missing a feature. I argue it should be banned.

I got SL7 and feels like having extra 30% tech. I don’t know Seal well enough to comment. But compare Model Y with SL7, they’re close in market segment.

Calling BYD “stepping back in time.” compared to Tesla Model Y?! Meanwhile, Tesla has clip-on phone mounts, no proper 360 camera, no V2L, no instrument panel, no HUD, no massagers, and the list goes on… The only thing futuristic is the cult & marketing.
