I’m getting inconsistencies between what the Tesla app reports and what my utility’s meter reports for both power and energy use. Tesla’s numbers are consistently about 20-25% higher. The correlation is perfect at all power levels. I even went so far as to measure the current going in to the...

As I was driving home this afternoon in a quiet residential neighborhood, all of a sudden my Tesla emitted a loud sound and the screen behind the wheel lit up with what looked like an incoming call. But the sound was not at all like the normal incoming call sound and my iPhone itself did not...

What evidence do we have that the P85D's top speed limitation will be changed in firmware 6.2?

I'm confused about torque sleep on the dual motor cars. My understanding is that it saves energy by using just one of the motors when cruising at a constant speed. Why is that good? I get it that the front motor on the P85D is more efficient than the big one in the rear. So that part makes...

As I was finishing my charge at the Fremont Supercharger today I noticed that it kept going for a while after reaching 100%, though of course at a very slow rate. But the charging rate display was weird: I didn't believe that it was really charging at 131 mi/hr so I switched the units to...

If I'm reading it right the main conductors in the cable from the HPWC to the car are 6 AWG. If that's right and code-compliant then why is it necessary to use #3 from the breaker box to the HPWC? Charging my car at 80A this evening I note that the HPWC cable is getting quite warm, about...

The way driver profiles works is a little weird. Some things are saved when you make a change and then click the Save button in the menu that helpfully pops down. Somethings are saved automatically with no confirmation. And of course, a lot of things are not saved at all. Here’s what I found...

Is it okay to put paint protection film over the parking sensors? Will it have any effect on the future auto pilot features?

Given that the Model S uses much more energy in cold weather I have to assume that it's continuously heating the battery to keep it up to an acceptable temperature. But it would take less (a lot less?) energy to do so if there was some insulation between the battery and the cold air blowing...

I have an unneeded brand new still-in-the-box MC240 that I'll sell to the first respondent for $1200 ($300 less than list). -- Bill Arnett [email protected]

I took my Roadster to Yosemite last Thursday and Friday. What a wonderful trip! But I'm wondering: Was I the first Roadster in Yosemite? Has anyone done that before? (I'm sure I wont' be the last!)

I've created a little web site with a couple dozen photos of my Roadster: Tesla Roadster #55 (for those not into astronomy, that's Venus and Jupiter in some of the backgrounds)
