If gas was pushing $7.00 a gallon I would be more sensitive to MPG's too. I didn't realize it had gotten that expensive in Canada...
I still say there is no replacement for the smoothness and power of a big V8.. Sure the smaller V6's can get the job done but, I am not looking for get the job done, I'm looking for an excess of power... When I had the 2014 with a 4.3 it struggled to merge on uphill on ramps empty, sure it got the job done but, It was not confidence inspiring.. That's just my personal preference I like big V8's and I always try to get the upgrade motor, I've always been let down when I haven't... When I had my Sierra I was disappointed but, satisfied with the 5.3 when I got the Silverado, with the 2016 Malibu I leased for my wife I wasn't really happy with the 1.5T, I'm much happier with the 2.0T in the Equinox I just bought... With gas around $2.50 - $3.00 a gal here if I get 22 vs 24 on the highway it's not going to make a difference to me at the end of the year but, it irritates me when I punch it and I feel like the truck isn't moving quick enough everyday... That's just me though, I've toyed around with a 6.2 on my next truck so you can see where my priorities are at.... To each their own and good on GM for offering options to suit a variety of preferences...
