Can the all-new 2023 Chevy Colorado and the 2023 GMC Canyon beat their poor EPA MPG ratings? The GMC Canyon has a high-output version of the 2.7L turbocharged I4 engine, and the Chevy Colorado does not. Mr.Truck and I take them on our new Denver 100 loop to find out.
We have been doing real-world pickup truck efficiency testing for around 10 years, but we now have a new MPG loop we call “Denver 100”. It’s a large highway loop around Denver, Colorado that also includes a bit of city driving.
TFL runs on Sinclair fuel and so should you. Download the Sinclair DINOPAY app and start saving as much as $0.10 or more per gallon on your next fill-up.
The new 2023 Chevy Colorado can be had with three versions of the 2.7L Turbo: base, Turbo Plus, and High Output. This Colorado Trail Boss has the middle “Turbo Plus” version. It is rated at 310 horsepower and 390 lb-ft of torque. It’s EPA-rated at 18 MPG combined due to aggressive 32-inch Goodyear Wrangler Territory MT “mud terrain” tires.
The new 2023 GMC Canyon can only be had with a high-output version that is rated at 310 horsepower and 430 lb-ft of torque. It’s rated at 19 MPG combined with smaller diameter 31-inch Territory AT “all-terrain” tires.
We drive both trucks on the same loop at the same and at the same time. The results really surprise the heck out of us!
Spoiler Alert: this Colorado Trail Boss registers 22 MPG, and the GMC Canyon AT4 shows 22.7 MPG at the pump. Whoa! This is a far better result than the EPA ratings suggest. It’s also better than we expected.
