With respect to those reports, I'd never expect best case mpg numbers for my use. But I note, 14 is better than my previous gas, a 351W, ever saw - except maybe downhill
. And speaking of Windsor, to me the best thing about the new 7.3 is where it's made. And I say that today as Oshawa GM closes after being in operation since 1954...
Anyhoo back to the OP... build pricing is now up on the Canuck site. For giggles, closest vehicle built to our current config is $68,989 CAD ('Net' incl delivery. No discounts or sales tax). Our 2010 was $58,279, ten plus years ago.
Using the Statistics Canada Consumer Price Index for historical inflation that old price calculates to equal $67,721 in today's dollars. So the 2020 pricing is <2% higher than the total CPI for inflation over that period.
That <2% would include: a more evolved vehicle, more power, more payload, more interior space, a 10 speed, rear locker and a few other small goodies. Not too bad I'd say. YMMV
