Record for my Mazda6.
Wife and I went to Montreal for the weekend, longest trip the 6 has done in one weekend. Usually take the van for long trips, but it was just the 2 of us.
Anyways, from Burlington to just outside Montreal (591km) average of 114km/h, 6.3L/100km going against the wind. Then getting into Montreal, driving around South shore, Laval, during the weekend (about 100km). Then from downtown Montreal to Cornwall brings the tank total to 809.7 km, at an average of 6.8L/100km. Did the numbers by hand as well, it works out to 6.79L!
From Cornwall to Hamilton (had to go get our kids) 515km, going with the wind, 5.9L/100km, average of 108km/h (Hamilton really brought down the average speed), but the cruise was set to 120km/h the whole way.
I am curious what the numbers would be if I had it set to 100km/h, 15C outside, and summer tires! Mid 5's?! Screw CVT!
