Until recently, we could only post Tesla's estimated range rating of 265 miles for the 85-kWh version of the Model S, but now there's been some real-world testing, conducted by Motor Trend, which proves that Tesla wasn't off the mark by much.
Best Answer: The state of the art Tesla with it's 6800 lithium ion cells specs at 244 miles per charge, conservatively driven, racing around might half that. Home conversions using 1000 pounds of lead acid batteries commonly have something like a 25 to 50 mile range. Non the less some of these conversion owners are pleased to do their daily commute with 2 cent a mile 'fuel' costs. The later versions of the doomed GM EV-1 could do up to 150 miles on a charge.
