I was an "Officiel" at the Rallye Vert this past weekend and had a lot of fun running as car 99 on the Saturday and working electronic checkpoints on the Sunday. Results are available
HERE. Being able to read French helps.
The best (non-electric) result was 3.5L/100km in a Toyota Prius plug-in over the 500km+ course. I think Darin's Insight could have easily beat that, having scored 3.1L/100km in this year's
SMCC Economy Run which has tighter timing and more twisty hilly bits.
Hope some of the local crowd got to check it out. The cars and displays were on McGill College Street in downtown Montreal throughout the weekend.
