On my first day driving the Leaf my estimated range was a meagre 134 kilometres. At first I drove it like my old diesel car. It's not so easy to explain, but as you drive the car it constantly keeps you updated with how much energy you are using or getting back through various displays on the monitor and dash. After a while you begin to notice that the throttle has quite a high resolution and this combined with the constant feedback on energy usage begins to train you to drive in a more energy efficient way. On my second day I woke up and after a full charge the car was telling me my range was 172km, it keeps a record of your driving style, so the range estimation is based on more than just how you drive on the day. It is also based on how you drove the previous days and weeks etc.
Yesterday I had to make two round trips from Celbridge to Clonee via Leixlip. There was fairly varied terrain. A few good hills, back roads and some more open roads. This is a picture of my dash after I got home, 67.9 kilometres travelled and estimated range is 101 kilometres.
The guy in that video was joking about Nissan saying you should acquire a Zen like state of mind, it's not a million miles from the truth. For me, it just made me far more acutely aware of the correlation between throttle and energy usage. I haven't had it long, but I think figuring out quickly that the throttle had such high resolution and that instead of pressing it 1cm, I could press it 5mm or less and achieve a similar result with less energy used - that was the key for me.
There are other things you start thinking about as well. Like how you don't really want to come to a stop, so instead of maintaining speed, maybe I'll just coast towards that junction (gaining some energy back in regeneration) and then having to use less energy to regain momentum as traffic has hopefully started moving again.
Of course you could do that in a petrol or diesel car, but petrol and diesel cars haven't been designed around informing you so well about your energy usage.
Coming back to how it trains you to drive more efficiently. Yesterday my wife and I drove to a restaurant to have a bite to eat. On the way over my wife drove and she started wondering out loud why the estimated range for her was going down faster than it had for me. I drove on the way home and when we got home, the estimated range was higher than when we had left the restaurant.
Anyway, I've only had the car since Thursday. These are just some of my initial thoughts on the car
