    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.

    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.

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