Yahoo Autos 2021 Chevy Tahoe/Suburban, GMC Yukons Improve City MPG
2021 EPA-estimated fuel economy numbers for the 2021 Chevrolet Tahoe and GMC Yukon, and for the Chevy Suburban and Yukon XL, have been announced.
They show a slight increase in city-driving fuel economy but a decrease in highway fuel economy.
The three GM SUVs are powered by either a 5.3-liter or 6.2-liter V-8 engine, and a turbo-diesel inline-six is optional.
The Chevrolet Suburban and GMC Yukon are redesigned from the ground up for the 2021 model year. They now feature an independent rear suspension which, among other things, yields more cargo space, and are available with a choice of two gasoline V-8s or a turbo-diesel inline-six, all of which are paired with a 10-speed automatic transmission.
The EPA has released fuel-economy estimates for the two V-8s, which are down in highway fuel economy and but see a slight increase in city-driving mpg. The 2021 Suburban with the 5.3-liter V-8 is down 2 mpg on the highway but up 1 mpg in city driving compared to the 2020 model. Its combined EPA fuel economy is 18 mpg for rear-wheel-drive models and 17 mpg with all-wheel drive. That's a drop of 2 mpg on the highway compared to the 2020 models with the same engine.
