Chevy sets a record; Ram keeps the full-size crown

by David Zatz on

Chevrolet has set a record in highway fuel economy with the new Colorado, also sold under the GMC Canyon label, by using a four-cylinder diesel engine. It has the highest highway mileage of any U.S.-market pickup of any size.

The Chevy/GMC twins have a highway rating of 31 mpg, with city mileage of 22 mpg. The added cost of the diesel option is $3,730.


The Colorado is sold in rear and four wheel drive, and as a chassis cab (unlike Ram 1500).  Tow ratings are up to 7,700 lb (RWD); the 2.8 liter four-cylinder diesel generates 181 horsepower and 369 pound-feet of torque, and is coupled to a six-speed automatic. Like the Ram, it has exhaust braking.

Ram’s VM diesel is a V6, sold for $3,120 extra, producing 240 horsepower and 420 pound-feet of torque; its maximum tow rating is 9,200 lb. It’s rated at 20 city, 28 highway, with rear wheel drive and an eight-speed; in HFE trim, Ram eked out an extra mile per gallon for 21/29, with a combined rating just 1 mpg short of the Colorado.

Ford has a top highway mileage rating of 26 mpg.
