Driving Dynamics

As we just had our first dusting of snow in Northeast Pennsylvania, I am now considering the purchase of snow tires for my X. I was less than impressed with the couple months of winter driving I had with the car when I got it in early 2017 with the Michelin Latitude Sport all seasons. My...

I own a 2013 P85+ (and a new X) and the car has developed an unusual (to me) sound. As it's out of warranty, I thought to ask here... At ride height settings above LOW, it has a sound similar to a pebble or nail in your tire... I'm thinking CV joint, because that seems the only thing that...

Sometimes I have to park outdoors. What's the best windshield cover against ice or freezing rain for Model S? I hate the idea of scraping the glass.

So, I finally took my P100D to the drag strip today, and the strip was crowded. I only made four 1/4 mile runs. The first run had a reaction time of 0.0881, and a final of 11.1558, with a final speed of 120.19. I'm a rookie, and I may be mistaken, but do I take the total time and subtract the...

I searched the forum a bit but wanted to see if I could get more definitive answers, or maybe some confirmation on stuff I think I know. Tesla states that it's $75 to change my 21" Turbines out to my 19" Slipstreams. Why so much? Apparently the TPMS have to get calibrated. I asked if that isn't...

I am planning a road trip from CA to TX on my tesla X. 75 battery. I have it mapped out with the supercharger stops in the car. Can I rely on the mileage that the car is recommending. When I drive to Joshua Tree- uphill - I use way more energy than the car expects, so I am afraid that the car...

My wife and I bought an S in September. We love it so much, juzt ordered a 3! Wow. Excited

What tires come with Model S? My 75 RWD entered production yesterday. 19”

Oops! Now I need two 19" OEM wheels and a tire. I was driving on a neighborhood boulevard with autopilot engaged and hands loosely on the wheel. The curb was a foot from the car. I passed through an opening in the boulevard. When the middle part returned, the car veered left and jumped onto the...

I am a happy owner of a new M75D. Great car! I am having one concern, however. Less than two weeks after delivery, I took a inaugural road trip. The first day, I was driving up a freeway in Northern California and suddenly the tire pressure alarm came on. I pulled over and a tire was flat...

I'm just curious about the community consensus about fog light usage.

I Ordered Model X 75D two weeks ago, waiting for late December delivery. But been thinking of switching my order to 100D. I would receive 100D sooner, first week of December. Only thing that is stopping me is the higher price haha. I just dont know if i can justify it, new uncorked 75D is now...

Looking for data (Max kw) with and without LM. Tesla claims they now allow this flexibility but not sure I if this is for all cars and models. Was hoping to see some p100d test data with and without LM with Ludicrous plus enabled art different states of charge. 565kw is the highest I've seen.

Here is how Tesla's Emergency Braking performs: 80-year-old cyclist killed in prang with Tesla Model S Here is how Volvo's Emergency Braking performs: I just whish Tesla's safety features were as impressive.

Just curious if anyone experiences sudden failures in their regenerative breaks? Ever once in awhile when I let the gas go I can feel the regenerative breaks kick in for a second, and then it seems to suddenly release and I’m jolted forward and need to apply the manual break.

I've been hearing scary noises lately when doing sharp turns with my Tesla. Basically, any time I take a roundabout at a quicker than normal speed and my steering wheel is completely turned to the left I hear my front left side ''knocking''. I have recently installed my winter tires on the...

I've read some S100D owners getting a performance increase lately. Are there any chances this upgrade will also show up on X100D, or already be activated on vehicles produced in October?

The question is: Should I get winter tires for my 2016 MX 90D? Not studded, just (softer rubber) winter tires. Last winter, it drove great, but now the original factory tires are wearing down (I've heard this is not uncommon) and we have a number of mountainous snow drives and road trips to do...

This thread, and particularly this continually updated post, is set up as both a Tesla Physics Index as well as a thread for new physics concepts. Although started in the Model S Driving Dynamics Sub Forum it is a general discussion across all vehicles. Files, when added, will be attached...

I have an AP “torture” course south of Seattle that I’ve used to evaluate AP 2.0 performance since 2017.36. The course has two right-lane exits after freeway turns, and the second exit occurs just after a rise and drop of the freeway, plus a sweeping right turn. There is also a freeway rise...

Is there a resource that shares the gear ratio of each motor on the dual motor Model S? I'm wondering if the front motor has a longer ratio. I believe if it did it would help with high end speed and efficiency/range.

On Friday I had my first accident with my MS. Icy conditions in Chicagoland. Was driving around 15-20mph behind a car that came to a stop at a stop sign. When I took my foot off the accelerator to slow down, I believe the regen kicked in and may have caused the vehicle to slide (instead of...

long story but in the market for a recent CPO 911 Convertible, likely S or 4S. Proud owner of a P90D for 2 years which i could not love more in terms of driving dynamics. Been test driving a number of 2014-2015 911 hard and soft tops. Anyway, impressions. - Lack of low end torque makes the...

I received 2017.44 firmware a week ago, just in time for a 1400 mile two-day drive from Phoenix AZ to Portland OR. I've been disappointed with AP2 performance (as many of us have) and the improvements I've seen in the past 11 months have been slow. OK, we've pretty much all covered that...

So I sold my P85+ earlier this year, and bought a P85D during the winter. It came with the Pirelli Sotozero winter tires mounted on 21" turbines. Lot of meat left on the tires. For the spring/summer, I took them off and put on summer tires (Hankooks Ventus EVO2s). So option #1 is to have...

With these upgrades happening to non performance Teslas, what is going to happen to those of us who opted for the performance versions? We know Ludicrous is just a software unlock, so will it be made available? It's not even a purchase upgrade currently. It doesn't seem right that those of...

I currently have about 25K miles of AP1 AutoPilot usage. I have also closely followed the threads regarding AP2 Autopilot driving experience. Today I took my first highway drive using 2017.42 a88c8d5. It seemed like AP1 AutoPilot driving performance was smoother overall and it impressed me...

Last weekend I had an aikido seminar to go to in Germany and a 7 hour drive to get there. So, I used this opportunity to test out the new camper mode along the way. Turns out it's working great, as long as you don't forget to turn off the alarm before it wakes you up ;-) Time to break out the...

Very very impressive, 0-60 in 3.5 seconds! How fast is the updated Tesla Model S 100D from 0-60 MPH and what is Chill Mode?

Ran my September 2017 build Model X at Bradenton Motorsports Park (updated 0-60). Results: 13.2 @ 101 That's pretty respectable given it's a base 5 seater lol. The only info I could find on 1/4 mile times was a review online where they clocked a 14.1 second run in the 1/4.

Ok I'm missing the three position turning lights (Sept build 90D) and can have the service center install the correct ones. I've been following the other thread on this matter and a comment about how poor they are got me thinking "maybe I shouldn't have them changed" Searched a couple of other...

After a month of owning the MX, I'm hearing rattling noises from both sun visors. Its not too bad until the road gets bumpy. Anyone having this issue?

Quick newbie question... I noticed with Ludacris mode enabled cars, there is a dedicated launch more (step on brake with left foot + gas right foot, etc). Is there an equivalent way of doing this for a 75 or 75D? If not, whats the best way to test the car from dead stop to 60 (aside from...

Which one would you rather have? Model X off-road videos

Hello, Has anybody had any (bad) issues with valet parking and your Model S? We picked up our CPO 2013 Model S 85 about two weeks ago and are hesitant to valet park it while going out on the town. (We are in and near Austin, TX, by the way.) Thanks! Martin

According to Electrek, the next software update is going to change the acceleration modes. Tesla releases new software update with ‘Chill’ feature to soften crazy acceleration and more Why would they do this? Is it for non P cars only?

Today I had the pleasure of a rapid tire deflation on the road. :-( Tried the inflater with goo but no way, still hissing. Called roadside and they got me a loaner wheel fairly quickly. (good experience overall BTW) However, when we took the wheel off, the wear was unreal (see below) A few...

A group of graduate students I know from Harvard and MIT are looking for volunteers to participate in a machine learning / data-mining project designed to give new insights about driving, performance, routing, etc. to drivers of Tesla automobiles. They're seeking Tesla drivers who are willing...

First saw this app reviewed by Ben over at Teslanomics. Welcome | Teslab Started using it mid October. Tracking tool for your car tracking overall efficiency of use, phantom drain and charging patterns as well as per trip calcs, etc. I am user # 4065 so I don't think it's widely known in the...

Hi All, I just got a call from my local Tesla shop in Massachusetts saying that my 21' Silver Arachnid Wheels I got from the referral program have arrived. I was hoping to get some advice from people who have both these 21' Arachnid wheels (or similar), as well as the normal 19' Slipstream...

No, not that Autopark... I'll preface this post with saying that I normally wash my own car in the driveway, but since I live in Michigan and the snow is already flying (with salt on the way soon), I figured that I should do a test run through the local automatic car wash. As I approached the...

Hi Everyone, I pre-ordered the Tesla Model 3 but am too anxious to wait and have also read some not-so-great, albeit early, reviews. For that reason, I am considering the purchase of a 2015, 2016, or 2017 Model S. Living in Boston, MA pretty much requires an AWD vehicle, so that is one...

Has anyone observed worsening of autopilot accuracy as a result of a dirty windshield? I assume the forward camera and maybe some other sensors are integrated into the rear view mirror, so are you supposed to keep the windshield in front of it clean?

Many board members have purchased and are very happy with the TSportline lowering springs for Model S. Unfortunately TSportline sold out of the springs and has discontinued keeping the springs in inventory due to a lack of demand. I exchanged emails with Jon at TSportline this afternoon and...

Can someone post maximum tire sizes which don't rub - 19" wheels to start. The issue is the stock tires don't last as long as they could because they are small compared to the weight of the vehicle - for efficiency reasons . . . i.e., 'fuel' economy. I've always been the guy who usually...

Seems my car has developed some unusual vibrations that I can feel in both the steering wheel and in the seat. The vibrations occur while aggressively accelerating between 50 and 70 MPH, and while cruising at 85 MPH. I started noticing the issue with my previous tires and it has persisted to my...

I own a classic Model S (no tire specific pressure readings on IC), and I got new tires a few months ago. Am I supposed to re-calibrate when new tires/sensors are installed? What is the right procedure to do this? I just checked my tire pressures, and they were down to 35 psi and I never got a...

Hello all. I've been told by a Tesla salesperson that Tesla used to outsource its suspensions from a third-party, but has recently decided to insource the suspension manufacture. Does anyone know if any of this is true? I ask because i have heard at least one complaint that a suspension on a...
