I find that autosteer (AP) works very very well as long as all these conditions are satisfied: 1. You are on a freeway.(because there are no surprises like cross-traffic) 2. The weather is clear (no rain or snow to obscure sensors or lane markings). 3. The lane markings are in good shape...

I had the Pilot Sport A/S on my BMW 328i (since replaced by my Model 3) and really liked them. But most folks on this forum report a 10% range hit.

I never recommend a Tesla to people who don't have home charging. Many people think that they can charge their car once/week at a supercharger and that will take care of all their commuting and errands for the week - but the reality is that the car looses a lot of charge between many short...

I agree that you should use TeslaFI, which will tell you exactly where all your 'range' is going. If you have the correct settings, TeslaFI will NOT eat battery (I recently left my LR AWD parked for 28 days, with TeslaFI running, and I only lost 20 miles total range!) When you do lots of...

I recently left my M3 LR AWD in our unheated garage (in Seattle) for 28 days. I lost only 20 miles of range! This surprised me because I expected to loose about 3 miles/day. I use Tesla FI, and have it set to ensure that the car goes to sleep. That may help ensure that the daily loss is...

I keep my battery meter in miles. In summer I multiply it by 0.8 to get usable range. In winter I multiply it by 0.7. Of course you can also use the energy display, but it fluctuates a lot. A good way to compute a conservative multiplier is to look at the wH/m displayed at the bottom on...

I have to say I am a big TeslaFi fan. It helps me understand my car's energy use, and make better decisions concerning travel, charging, and energy costs. If you are an engineer, you will appreciate it. If you are an art history major, probably not. Still, if you read the posts on this...

You should lose less than 10 miles overnight, probably closer to 5. However, starting with a cold battery will give you a pretty high wH/m when you start out, probably in the high 300s or low 400s. For a conservative estimate figure 70% efficiency, so your 130 miles from supercharger to hotel...

For anyone obsessing about electricity and energy use (as I do), I highly recommend that you sign up for TeslaFi. It will give you detailed usage and consumption figures, and you will be able to see exactly where all that electricity is going: how much you use driving, how much you use just...

The SR+ may be a better value than the LR AWD, but in Seattle you will never regret spending that extra $ for the bigger battery. Why? 1. In Seattle at this time of year we average only 70% of rated range (driving normally with heat at 70 deg). So if you charge your car to 90%, you...

I usually figure 70% efficiency at this time of year. 70% of 150 = 105, so you are right on the mark. (You will learn over time that the energy consumption is very sensitive to temperature, heat/AC use, speed, and elevation gain).

70% is pretty typical at this time of year. Also your car will probably greet you every morning with 5 or 10 miles less range than the night before (unless you have charged it that night).

Welcome to autopilot! It works great all the time - except when it doesn't. It works poorly at all on-ramps (predictable), when the sun is shining onto one of the cameras (kind of predictable), and at other random times (unpredictable). There's a reason that it still is in 'beta'.

Mud flaps WILL make a big difference! I recommend that you do that first. Don't overthink them, for heaven sakes. I recommend the $40 BASENOR ones on Amazon. They are quick to install, fit well, and will absolutely keep your car cleaner. (Just look at how wide your front wheels are - every...

Over the 6 months that I've had my M3 the display has gotten much better (if you can believe that) but you are correct - there is still a lag between reality and the display. Not very confidence inspiring.
