Five Days with a Tesla Model S P85+ compared with an Active E

Our Roadster is ready for pick up… So, we’ll be getting it back later today.

So, I don’t know if it’s normal or not, but I was hoping that Tesla would send an update to the P85+ loaner from firmware 4.5 to the latest, but it did not get it during its five days with us.

Aside from the lack of a hook for a jacket or dry cleaning…

So, a few more nits and revisit a nit and positive… Let’s start with combining these two from the three day post:

“4) This might be because it’s a loaner, but I can’t sync my contacts nor recent calls on the car. It is ALWAYS refreshing. I just disabled it. As a result, I have to dial by number or launch the call from my phone. Once again, the car IS a loaner.”

So, these two might be related… But inconsistent. The lack of sync might be a “privacy issue” and ensures that folks with loaners don’t leave their contacts on the car…

However:

“3) Automatically remembers places that one has charged (and what level charger to set up for.)”

This is not consistent because my home (and presumably other homes) are cached in the car.

Lastly, I am unimpressed with how well the guesstimator for the Model S functions. I like to drive in rated range rather than ideal range. This is just too much car to drive at 55 mph.

As a result I compare my rated range with my actual consumption. I find that the Tesla is still too optimistic with my expected range. Now, the effect is minimal considering how big the battery is, however, the Active E is more precise. For example after a few days back from service and consistent duty, the Active E will predict a certain range and when I consume the mileage, the range left over is consistent. Whereas the Model S would be lower than the consumed miles.

I would expect Tesla to have better prediction algorithms than BMW, but it does not seem that way.
