Just did a 56.1 mi mpg test run on the highway to Sainte-Anne-Des-Lacs and back. My goal was to do more than 100 mpg, and of course I achieved it! Went at an average speed of ~50 mph. Did mostly DWL (lots of hills) on the highway and P&EOC in the city part of the run. Tried to stay in Lean Burn at 125 mpg (target). Did 3 Engine Off Coasting on long downhill and I was really suprised how long and well the Insight coasts even with missing undertrays.
Temp was around 30°C and I had plugged the car 3 hours before departure. c°WT showed 72°C before starting. Highest measured c°WT was 96°C (I had Francis' Fire Blanket and was 100% lower grille block, 0% upper grille block). Tires at 55 front, 50 rear, verified it before departure. I had no passenger and my 2 mirrors where not folded. No HVAC at all during the trip. Windows up all the trip. IT WAS REALLY HOT INSIDE!!! Drinked alot of water. Listened to music tho...
My 12v battery was fully charged and SG-II showed 12.9v before starting and 12.6v when I came back. My 144v battery SOC gauge showed 2/20 bars before starting, and 19/20 bars when I came back. I had a medium tailwind when going to SADL but I was climbing alot. Then when returning home I had a medium headwind but I was going down alot.
The results : I did 106.9 mpg (US) | 2.2 L/100 km!
