The BMW 550i[1] has very similar size, peak power, and peak torque ratings compared to the Tesla[2][3], so let's use that as a comparison. Obviously, torque availability at 0 rpm with a flat curve is the notable difference, but remember that launch control in the BMW will also occur at peak power RPMs with a clutch or torque converter taking up the difference in road "RPMs", so it's not that dissimilar a comparison at least in regard to the strength of gearboxes, half-shafts, differentials, axles, CV joints, et cetera. (Consider too that the BMW has changeable gears, not a fixed ratio; the complexity should give Tesla a nod for transmission strength) BMW 550i (base) vs Tesla Model S P85 Cost: $63,900 vs $87,070 Curb Weight: 4277 vs 4647 lbs Peak Power: 445 vs 416 Peak Torque: 480 vs 443 lb-ft 0-60 mph: 4.5 vs 4.2 seconds Top Speed: 130 mph for both So I think my point stands; I suspect a software update in the Tesla could likely alleviate strain to the gearbox, without much tangible sacrifice in specs. I'm curious what "to the wheel" power looks like after the final differential ratio, but have to leave :) 1 http://www.bmwusa.com/Standard/Content/Vehicles/2014/5/550iSedan/Features_and_Specs/550iSedanSpecifications.aspx http://www.bmwusa.com/Standard/Content/Vehicles/2014/5/550iS... 2 http://www.teslamotors.com/models/specs http://www.teslamotors.com/models/specs 3 http://www.teslamotors.com/models/features#/battery http://www.teslamotors.com/models/features#/battery
