Could I have a comparison of 3 electric cars? BMW i3, Tesla Model S, Nissan Leaf?

Hi, I’m a student conducting research for the electric vehicle my college is using for Solar Decathlon 2015. My team is struggling with choosing a car that we’d prefer from the Nissan leaf, BMW i3, and the Tesla Model S.

We could really use any experiences that any of you have had with these cars, and how to maximize range and efficiency. The largest problem we have is that it needs to not consume too much energy and all we have to go off of right now is the ideal situations and the information we get from the company. So if any of you could shed some light on this that would be great :slight_smile:
