General Motors has revealed EPA fuel economy ratings for its new 2015 full-size SUVs from Chevrolet and GMC, with the new models being nearly 10 percent more fuel-efficient on the highway over their predecessors.
The 2015 Chevrolet Tahoe and Suburban and GMC Yukon and Yukon XL with the standard 5.3-liter V8 engine get an EPA-estimated 16 mpg (14.7 l/100 km) in the city and 23 mpg (10.2 l/100 km) on the highway with two-wheel drive.
The highway mileage represents an improvement of nearly 10 percent over the previous models, while city mileage is 7 percent better.
The GMC Yukon Denali and Yukon XL Denali are also offered with a 6.2-liter V8 engine rated at 420 horsepower and 460 lb-ft (623 Nm) of torque. EPA-estimated fuel ratings for two-wheel drive models are 15 mpg (15.7 l/100 km) city and 21 mpg (11.2 l/100 km) highway.
These figures are expected to be similar for the 2015 Cadillac Escalade as well, which shares the 6.2-liter powertrain with the GMC SUVs and the platform with all four GM full-size SUVs.
Both V8 engines are mated to a six-speed automatic gearbox. All five SUVs will go on sale this spring in the U.S.
