Rather nifty Tesla Model S range per charge simulator featured in this video.

I'm playing with the 'Range Per Charge Simulator' to show the effects of:

1. Wheels size (19" vs 21") 2. Speed 3. Outside temperature 4. Air conditioning or Heat on/off

in Miles (first minute of this video) in Kilometers (second minute of this video)

for the 4 Tesla Model S models : 70D, 85, 85D, P85D (July 2015).

"How many miles (kilometres) can you drive with this car?"

Give it a spin yourself from Tesla Motors webpage here (it's about 3/4 of the way down the page)
