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)

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.

Beat myself by 1 Wh/km, im pretty sure it was because the woman in the Maxima behind me tailgated me all the way to work.

+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!
Still ways to go to reach your commute numbers, though...
