    I weighed my car today and unfortunately but not surprisingly it is heavier than I hoped. I used my buddy's race car scales and came up with 2790 including tool bag, floor mats, fix a flat, fan shroud and hardtop. Tesla says the car weighs 2723. Subtracting the 22 pounds for the hardtop makes for 2768, still off by 45 pounds. The heavy floor mats weigh 3 pounds total and the fan shroud might weigh 5 pounds? Giving them the benefit of the doubt, let's call those two items 10 pounds, that means we are still off by 35 pounds and the car really should be weighed with the soft top on, which would add back another 10 pounds. Have I missed anything? The scales we used were of course not certified, but I doubt they are off that much. Has anyone else out there weighed their car?

    I think a weight reduction for the Roadster could be got by decreasing the battery weight. Does anyone know if Tesla is going to update the battery for the Roadster?

    Elon has hinted that they plan to do something for Roadster owners next year. My bet is on a lighter, higher capacity battery based on Model S cells.

    Drop your floor pan. You will find a few pounds of rocks wedged under there. Do you have sound proofing?

    Could Tesla weighed with the top off? Still a legal car. Tire and rims? A gallon of wiper fluid? Was it charged? There was a thread a long time ago calculating the weight off the electrons in a full battery.

    I expect there are weight differences per model year. The front fascia and back air diffuser are different from 2008 - 2011. Also, did they weigh the car using the carbon fiber upgrades?

    Answer: 3.4 micrograms for Model S. How much more does a fully charged MS weigh? That comes out to 2.1 micrograms for Roadster.

    Don't think that's gonna do it.

    2768 vs 2723? OMG, 45lbs. is close. Not like promising Model S at 4000 lbs. ...

    Anyway, Car and Driver listed it at 2760, so only 30 lbs off there. Others listed it at 2790 lbs. The 2723 is for the 2008 v1 Roadster - if you've got a later one you've got more sound proofing.

    Do you have the forged wheels? Which tires? This doesn't seem worth worrying about to me.

    A battery based on Model S cells would be good for Roadster in my opinion.

    I didn't think about sound deadening, I guess that could weigh twenty or thirty pounds? My car does have the stage one kit. Does anyone know what those kits weigh?

    Thanks

    My guess is that it was weighed with the soft top. I don't think it would be right to weigh without it since that is the way it is sold.

    The sound deadening is like 20 lbs. About the weight i SHOULD lose.

    I'm sure you are right about the weight differences, but their literature shows the same 2723 for the 1.5 and the 2.5. It looks like they just used the old number.

    I do have the forged wheels with the stock Yoko tires. The reason I'm doing this is to get 0-60 times for my car. I have a G-tech meter and it requires that you enter the vehicle weight.

    I'm curious about that too, I'm curious what's legit and what's not. I do believe it has to be weighed as if it was being sold to a customer. By the way I believe the hardtop is lighter than the soft-top. Hardtop feels like a feather to me and the softtop feels like a soggy oversized sponge!

    The weight is only used to calculate the horsepower measurement, you don't need it for the 0-60 time itself.

    You're right, it had been five or six years since I used it and had forgotten about that. I waited probably a week until I got the car weighed before doing my 0-60 tests. I guess reading the instructions would have been helpful. :biggrin: It was fun getting the car weighed.

    Thanks
