    I managed to get 174MPGe (1.2L/100km) one day, basically hit all the green lights, smooth cruising at 80kph (which is the speed limit)

    I'll post my numbers soon...I get great numbers going to work..all downhill.
    On the trip home, the numbers climb exponentially.

    Is that downhill or what? The lowest I've seen on the trip meter was 139Wh/km a couple weeks ago over 46.3km. And that included a lot of 55km/h driving...

    My most efficient round trip to work (13.6 miles each way) was around 245 wh/m. In warm weather, it's not hard for me to get 280 or less. In the depths of winter my energy use was frequently well over 500 wh/m and I am fairly conservative about using the heater. Toward the end of the winter, after reading a few threads on this forum, I became convinced that part of the reason my energy use was so high was because I was not using range mode. In cold weather and when not in range mode, the car spends a lot of energy keeping the battery warm. In range mode, it spends much less energy on this. I've read that the reason the car spends so much energy heating the battery is so that once the battery gets warm you can use regenerative braking but I haven't seen any analysis of the tradeoff between the energy gained from being able to use regenerative breaking vs the energy spent heating the battery. I suspect that when it's really cold, you spend much more energy heating than you can typically recover by braking. It would be interesting to see an analysis of this.

    I drove a 150km round drip with an average of 168 Wh/km. Speed ranged from slow traffic up to 130km/hr. How much of an effect do you think my new aero rims are having?

    I've seen 225 Wh/mi for 11 miles from charger at home several times without making special effort, moving with traffic, maybe even faster.

    +1 Lloyd. As I often ride my bicycle. Not only does it get terrific MPGe (more than 5000 miles and I have yet to need a charge) but it is great exercise as well.

    Beat my own record again, this time a nice lady in an white Acura RDX tail gated me to work... man i love tail gaters! im wondering if the size of the vehicle was a significant factor or if it was just 1 light.

    The only time I can come close to your numbers (or even beat them) involves a 200ft elevation drop down the Niagara escarpment. Not sure how you can do it!

    I've dropped down below 200kwH, but that was with me going local to avoid traffic. That was about an hour's worth of local driving to get to it at approximately 30mph

    Hey AC1K, I'm at 199 Wh/km lifetime average as well! :) Still ways to go to reach your commute numbers, though...

    Still, I've only had the car for a week, so without the numerous test drives I've given my averages will probably still come down.

    How in the world did this happen?
    LOL if you can answer this, you may have the answer for world energy crisis.

    Easy. Always drive downhill.
