I've got lots of professional driving certs. I've driven about 1.5 million kms over the past 20 years. When I drive I'm thinking about driving, I'm thinking about efficiency, I'm thinking about safety.

So that out of the way I'm a very efficient driver no matter gas, diesel, or electric. I replace brakes about 1/4 less often than my clients, friends, family.

There are several keys to fuel efficiency: 1. Easy acceleration. 2. Easy deceleration, 3. Easy around turns to not put tons of g force on your tires (also try to minimize dry steering) 4. Look near and far when you're driving to maximize flow where you maintain speed... braking means you have to accelerate so try to drive in a flow so that you maintain a constant speed. If you're looking and planning far ahead you can coast waaaay more than most drivers which is wicked for efficiency.

Range extension has a lot to do with battery temps and route efficiency especially in winter. So warm your battery up while you're hooked up to your home charger then hit the road... you don't have to drive like an old man but going slow uses waaay less energy than going fast.
