Energy consumption test

[Blue heaven]

Disclaimer: Not an official test, just a bit of fun.
After MDK and a fellow Tesla driver compared energy usage after driving the same QLD road under similar conditions Technophile took the opportunity of today's WA Tesla meetup to take a comparison one step further, all cars drove the same 72km+ route at the same time generally keeping a distance of 6-8 car lengths, terrain was fairly hilly, average speed was 61kmh and outside temp was 18c, conditions sunny and dry.
Carrying the weight of extra passengers and a second charger was factored in, sunroofs, spare tyres probably could have been too but I think tyre size and pressure is a critical factor.



Tyres Pressure Model Energy Occupants Dual charger A/C
19s. 3.1bar P85D. 13.7Kwh 2. No. Off
19s. 3.1. 70D. 13.8. 2. No. ?
19s. 3.1. 70D. 14.1. 1. No. On
19s. 2.9. S85. 14.4. 2. Yes. Off
19s. 3.1. 85D. 15.2. 1. No. On
19s. 2.9. 70D. 15.3. 2. No. On
19s. 2.7. S85. 15.3. 1. No. On
19s. 3.1. S85. 15.7. 2. No. Off
21s. 2.8. P85. 15.8. 3. Yes. On
19s. 3.1. S85. 16.3. 2. No. On
21s. 2.9. P85+. 16.3. 3. Yes. Off

Not a great reco for 21" tyres!

No at all, interesting that the P85D was the class leader, AC makes a big difference!! Great to see the tyre pressure, AC and wheel size making a demonstrated difference. I really think when I get my Tesla it is going to make me a better car owner!!

Running two identical cars comparing 19s against 21s over a 50km+ route would be interesting, best to be done on a low traffic road, using TACC with at least 6 car lengths to take aero out of the equation, same climate control setting, fair bet it's going to show a far wider disparity than the Tesla range calculator does.

Interesting to see the effect of the D

Were any using cruise or autopilot and what regen setting were they using.

I will ask the question, all bitumen roads but a lot unmarked.
