Musk has said the SpaceX vectored thrust package adds 3 g forces to any direction and says expelled gas will be immediately replenished depending on power draw. So I will add 3 gs to estimates of all the base roadster's g loading. We have to keep in mind that the tires, and the down force and the weight of the battery limit (even if Maxwell tech lightens) the Roadster S where on the other hand the base roadster matches Top Fuel ftlbs torque by some measures. Roadster S vs Top Fuel 4.5+ gs s off the line 0-60 for roadster S vs Top Fuel's 6 gs off the line, yielding .6 seconds 0-60 for Roadster S, vs .4 0-60 for Top Fuel or 66% of 0-60 acceleration for Roadster S, after that the dragster walks away from the Roadster S hitting 8 gs at 1/8 mile and 200 mph. But not bad to have %66 of Top fuel 0-60 although I am certain an electric dragster could beat top fuel possibly by a large margin- Tesla could do a ultracap enhanced battery demonstrator to shake up Top Fuel. There is apparently also a higher power COPV they could use but I guess that's not deemed safe for land vehicles. Roadster S vs F1 Roadster at 4.5+ gs is 300%-400% of the 0-60 acceleration of F1 and Roadster S at 1.00 second 0-100mph or 400% of F1 acceleration Roadster S at 4.7 gs for breaking force is 85% of F1 breaking force Roadster S at 5.3 cornering gs is 66% of F1 cornering force So it looks like even with the huge advantage on acceleration the Roadster S wouldn't beat F1 on most tracks. But the Roadster S is 1/44th the cost of a F1 car and it is 26000x more fuel efficient than a Top Fuel dragster- top fuel dragster is literally 200lbs of fuel per mile. Guessing if the cornering could be improved by about 25% and the braking about about 10% it might be able to compete with F1 on a standard track but my wild guess is couldn't compete if breaking and cornering didn't get within 90% even with huge acceleration advantages. What do more knowledgeable people think? Maybe I did the G calculations wrong for all of it. I used the current hyper car limits for cornering and breaking gs and added the 3 gs for the SpaceX package, I simply added the calculated gs for the base roadster plus 3 for the acceleration. I'd like you to contemplate a street-able machine that is totally civilized on the road but can do everything on the track at an average of about 5 gs and that includes, cornering, breaking and accelerating. Its a 5 g machine. A Top Fuel dragster will accelerate at 8 gs but you can't corner in it unless you load it on a truck. A F1 will corner at 8 gs but you can't accelerate more that about 1.4gs. A Tesla Roadster S is like crossing Top Fuel with F1 and making it perfectly street able with a 620 mile ranges and silent off track performance. You don't have to rebuild the engine after every race or replace a bunch of parts as with F1 and top fuel. Also a Top Fuel dragster still costs about 2x what a Tesla Roadster S costs, and neither will self drive and neither is perfectly green with almost no moving parts, neither seats more than 1 or has a trunk. I suspect Musk was saying that anything over 3 gs is over the practical limit of human endurance- space shuttle was limited to 3gs going up for comfort and delicate experiments, but really 3 gs is the red out limit for negative gs, Saturn V went 9 gs for much of its flight and fighter pilots sustain 9 gs with gs suits for positive gs.
