    S 75 (RWD) uncorked regen

    I've been researching pre-owned model S, specifically 2017 75 RWD coming off lease that have the 4.xx 0-60 via a larger (performance?) rear motor. Can anyone comment on the regenerative braking for this specific setup? Other handing/driving experiences would also be great. Been searching for...

    Regenerative braking reduced warning

    This was brought up in another thread but got way off track. I'm coming from a Model 3 to Model Y and since the temps here started dropping (in San Jose area, daily temps under 65) I've been seeing a constant "Regenerative braking reduced" warning. Rarely if ever saw that in the M3 unless...

    Fall is here! Regen is already restricted...

    I was somewhat surprised but not startled to see that my regenerative braking was restricted this morning. Although the air temperature was in the 60s when I left for a short drive about 10:30 AM, the overnight low in my parking lot had been 46F according to my recording thermometer. Hard to...

    Maybe a dump question, but it's physics

    I'm interested in the efficiency of the Tesla M3 regeneration system. So, I wonder if anyone has done a test, say, like Pike's Peak or Mt Washington. I envision recording the battery charge at the bottom, then driving to the top and noting how much was consumed in the climb. Then, going down...

    Model Y Owner for 24 Minutes

    After months of anticipation, I picked up my Model Y today in Northern Virginia. The car was absolutely beautiful and the walkthrough (from a distance) was very helpful. At the conclusion of the process, they help you set up your phone as your key and send you on your way. As I drove off the...

    Uneven Re-gen Braking Feel on P3D+

    Hi all, I saw a recent post on "braking feel of the Model 3" and this is a bit on the other side of braking on the Model 3, the re-gen braking. I had two very different cars before my P3D+, a 335i and an eGolf. The regen braking on the eGolf was predictable, you could predict where it would...

    Some general confusion / frustration with reduced regenerative braking

    2020 Model 3 Performance, recently switched back to 20" stock wheels from winter setup. Anyway, the weather has been getting warmer where I live, and I've been looking forward to being able to finally have some full regenerative braking capability. However, as shown in this photo, even during...

    "Regenerative braking has been improved" on "Legacy" 2015 S70D thoughts

    I thought improved regen was only going to be for Raven/M3 when I saw it somewhere in update notes on Electrek. But It seems I did get "something" on my 2015 Model S70D(Instrument cluster prompted of improved Regen). Didn't think any of us "Legacy" car owners were ever going to get anything of...

    Thought I'd give 100% charge a go on CCS

    A wee bit of work is needed on their algorithm (I get it's dynamic environment but still...) the last 5mins took 25 minutes as it slowed the rate down from 40kW to 2kW. At 100% it recalculated 5 mins due twice for 15mins. With retrospect it's obvious but at 100% you have no regeneration braking...

    Cold weather inflatable bed auxillary battery heater

    I have seen several threads on the effects of cold weather on battery dynamics and had an idea: If I were faced with severe cold weather and wanted to maximize both the longevity of the battery and availability of regenerative braking the goal would be to maintain the optimum battery temperature...

    Regenerative Braking

    Does regen braking occur when the foot comes completely off the accelerator throttle or when the foot depresses the brake pedal?

    Battery range questions...

    I placed a deposit on the Cyber... I am currently driving a Volvo hybrid. I am considering buying an S or 3 until the cyber truck is available. I admit to having range anxiety, and owning an older 60 is out of the question, but a 75 or 85 might be possible… Here’s the question… I live in a...

    Test Drive/Regen Braking Impression

    Greetings! I finally took a test drive in a Model 3 recently. I look forward to ordering one soon. I was initially surprised by the aggressiveness of the regen braking. Even at the lower setting, I thought it was too much. However, I understand the purpose (I believe) and that is to slow...

    Raven regen poor in cooler weather

    I have a 2019 Raven MX performance and now the weather is getting cooler I’ve noticed regen is incredibly weak. Almost non existent with temps around 50oF. My previous MX regen was way stronger and I wouldn’t get the dashed yellow lines until temps into the 30s. Anyone seen the same issue?

    Regen braking dramatically reduced.

    Normally when I was able to drive almost completely with one pedal and only at stop lights would I have to add the brake when under 10 mph to come to a full stop, but lately after V10 my car's regen braking has gone to almost nothing until I get down to about 20 mph then it kicks in and I have...

    Regenerative Braking: Standard Mode Quit Working

    I have my car set to Standard for regen braking. This morning, I unplugged the cable, planted my foot on the brake, flipped into drive and took off. A surprise happened as I approached a stop sign: The car barely slowed. Hit the brake. I checked the driving screen and standard regen braking was...

    Regen Braking klunk from front left wheel

    I have a new to me 2016 S75D. It's a lease return purchased directly from Tesla and I love it. One issue I've noticed is that if I take my foot off the gas and let the regenerative braking kick in, there is a brief but obvious klunk from the front left wheel area. Car has a 4 year, 50K full...

    New Feature Request: full regenerative breaking when pressing the break slightly

    I was surprised today when I played with my drive settings to find that switching regenerative breaking from low to standard actually affected more than just the pedals. I would have expected low to mean that if coasts better and standard to be more of a one pedal driving experience. I...

    Strange icon on dashboard / warning sign regenerative braking

    Sometimes I get a weird warning icon when regenerative braking; see attached image. I have called support and they said there was nothing wrong with my car, so I dont have to be concerned about that warning. However, a warning is still a warning and if not inportant why give warning ? So can...

    Where are the brake regerators

    waiting on my model s to be delivered via home delivery in 14 days! I stopped by the service center to just be close to new Tesla’s today. Tons more 3’s and a few more s’s than usual and a huge amount of trade ins on the lot now. Looking closely at the recently delivered s’s I don’t see any...

    New Ownership Impressions and Advice

    I love the car, it's faster than expected. Solidly built. Intuitive, if you play with the menu screen while it's parked first. Definitely needs a home charging station installed (at least a 240V plug). Here's a detailed review after picking up the 2018 Model 3, and the first 300 miles driven...

    Regenerative Breaking Limited at Moderate Temperature ( 68 F)

    2016, X 75 with 20" tires, starting charge usually around 70 - 80 %. I have a route which I have been travelling for the last 6 months. I have an 8 mile drive from my house to the golf course which is level except for one hill at the very beginning/end of the trip (at my house). I am a...

    Change in regen braking in v8.1 17.34?

    I just got the 17.34 update installed. Has anyone noticed less of a slow down (almost none!) when lifting your foot off the accelerator pedal (normal regenerative braking on)? I almost got too close to the car ahead of me at the stop sign today and noticed this change immediately since the...

    Regen Braking Not Working

    I charged my battery to 100% for a road trip, and randomly my regen braking stopped working for an hour or two. When I'd let off the gas, it would coast like an ICE car, and no brake lights would come on. Has anyone else experienced this?

    Did the Bolt ruin it for me? At least a little?

    Recently I drove a Chevy Bolt at an EV event. Just a short drive, a couple of miles on local roads, nothing dramatic. But the regenerative brakes were surprisingly powerful. They could and did bring the car to a complete stop. At the time, I questioned the salesman how they did it -- whether...

    Regenerative braking not working in cold?

    Anyone else experiencing regen brake not working in the cold? I'm here in Texas and it gets no where near as cold as up north and I find it surprising that regen brake isn't kicking in till i hit about 20-30 mph. Thoughts?

    Regenerative Braking with 100% Charged Software-Limited 60 kWh Battery

    In this video I am demonstrating regenerative braking with a 100% charged battery in our new Tesla Model S 60 (applies to a Tesla Model X 60D as well), which is one of the advantages of having a 75 kWh battery software-limited to 60 kWh. This clearly confirms that regular charging and...

    Regenerative braking and charging limit

    I have tried to find the answer to this question all over, and I can't quite figure it out, so I apologize if this has been answered before... I live at the top of a fairly steep hill that is about 1000 feet above sea level. I pretty much lose the entire 1000 feet over the first mile of my...

    Regenerative brake settings and lead feet

    I test drove (and ordered) a 90D and commented on how little the car would coast with my foot off the gas. The salesperson directed me to the regenerative brake settings and I changed it to low. She said with this setting, the brakes wear out much faster (believable) and total mileage is...

    Regenerative Braking Safety Issue

    I have been trying to get a response from Tesla about this issue since January 2015. I have called my service adviser many times and have written multiple times to ElonMuskOffice. The issue concerns a safety issue regarding the Model S regenerative braking system performance on ice. The...

    Why don't regen brakes stop the car completely?

    I haven't been able to find the answer to this. Would be nice to roll to a complete stop for true one-pedal driving. Does anyone know why we still need to use the brakes for complete stops?

    Regen FAQ?

    This seems to be the subforum where regeneration is discussed most frequently. I see anecdotes and references to people having done regen experiments, etc. Does anyone know if there is a central repository for regen information? I was initially just curious as to what % of braking energy is...

    Regenarative breaking on ice/snow,sliding ?

    Regenarative braking on ice/snow,sliding ? I read from Swedish car magazine "Teknikens Världen", that on winter regenerative braking can make cars back slide, if braking is set to "normal". I would like to hear Tesla owners experiences about regenerative braking on ice/snow.
