[Moderator Note: Moved from here: Tesla will introduce few next year. - Page 8] Model S already has a cca 400 kW battery, why would you wish for a weaker one? If you mean higher capacity / more range than use kWh

Sorry - thought you knew what I meant as I also included the driving range. Anyway - now it is fixed.

Obviously you knew. Even Tesla themselves sometime use kW instead of kWh. I know it's wrong but hey, what's the big deal.

I never saw Tesla being so unprofessional and lame as to use kW instead of kWh. And deal here - it is really confusing to see, and cast doubts whether to believe what was written or not. Again, it is not simply wrong, but in fact confusing. - - - Updated - - - PS. Just like someone using kilograms instead of kilometers to describe radius of the Earth...

Exactly, it is wrong and confusing. There are already too many people that can't tell the difference between kW and kWh. Those who understand should use right terms and not add to confusion. Especially because max battery power (measured in kW) is the primary factor affecting battery life.

OK people....enough discussion about the typos of someone who has english as a second language. I hope all the engineers are smart enough enough to know when a simple mistake is made and to understand it and move on?

Well... Fuel economy (with gasoline) is properly measured in Gallons per Mile, which has units of volume (gallons) per distance (mile), which in metric is m^3 / m, or m^2. So gas mileage is technically measured in square meters. Figure that one out

Imagine the fuel stretched out along the road in the shape of a very long cylinder, and a car that picks the fuel up and burns it as it goes. The fuel economy is the cross-sectional area of the fuel cylinder! Let's see - 10 liters per 100 km. That's 10/1000 cubic meter of fuel, and 100 000 meters. (10/1000)m[sup]3[/sup]/100000m = 0.1mm[sup]2[/sup]. :biggrin: *edit* Dang - xkcd/woof already did that *edit 2* There's an error in the final equation in that XKCD post, a "per bird" is missing - email sent
