    Does the Off Road option decrease range?

    We don’t know yet, weight and what all will be offered. We heard the AWD could be a 10% hit

      The more drag the less efficient. The more weight the less efficient. The more speed the less efficient. 10% hit for AWD 20% increase in fun!!

      Where did they say that AWD will be 10% less efficient? It could be more efficient, with the three motor system 98% of the time it will be using the single rear motor only. You only need all three motors when getting out of the snow or when flooring it, when you are cruising along a single motor is sufficient.

        Chris mention the hit in a video.

          Sure did, but my recollection of the remark was that the 10 percent decline for adding the rear motor was a first-blush decline in efficiency before, say, power shifting or other approaches to boost efficiency were tried. I.e. with some optimization, the hit for the third motor could be like 3-5 percent.

          It is kind of like adding a fourth wheel; the shorthand estimate of the increase in drag and rolling resistance would be 25 % but by placement of the wheel and other strategies, the hit might be as much as 10% lower because of other design efficiencies.

        The addition of the weight alone (for the third motor) will make it less efficient – I think it was noted somewhere that consumption/efficiency drops by 1% for every 30lbs of weight.

        Joshua Rosen, I think it would be less stable with just rear wheel propulsion.

    It must, at least a little, or they would have designed them all that way. Think about it.

    Likely, though we don’t know by how much, nor if it is an option we can change to and from at will depending on the driving circumstance and need.

    I’m thinking about adding the off road option. Does anyone know what the ground clearance will be from the bottom of the wheel cover to the ground after the option?

      This has been answered already…

      Since the std GC is 5” at bottom of the wheel covers and the belly is 9”. They hope to realize 2” additional to this GC, BUT until they do it there is no spec.

    Still haven’t seen whether the off road option decreases driving range.

      It depends what is included and “what all that” weighs

      We have read about a a 1% range hit for ever 30#…

      Time will tell.. Hopefully in one of the remaining development vehicles… they will outfit one?

      You don’t have to commit to that kit until your order come due…

      Well, yes, the off-road option is sure to reduce the range.

      More of the tires will be exposed for one thing. Those wheel skirts are there to reduce drag, so less wheel skirt means more drag, leading to less range.

      What we don’t know: By how much?

      Until they decide on, test and reveal their simulated wind tunnel tested off-road design, we won’t know.

        Yeah!

        And the true off roader type may change out the low roll tires for heavier tires. I have some primitive roads. People may justify some things for their needs/lifestyle, but yet keeping it simple

        Who knows some may like “the look”too ( only an old rendering but the attached photo was once posted ) It might be neat to lock up for light off road and return for paved road

        I need it more for height, but without impact to ride…as paved roads are most of “my trek” TBD
