The fuel economy estimates for Colorado and Canyon are critical in the battle with the 2015 Toyota Tacoma, and the Detroit trucks beat the Tacoma.

A two-wheel-drive 2014 Ram 1500 with a 3.6-liter V6 engine and eight-speed automatic transmission returns 17 mpg in city driving and 25 mpg on the highway for a combined rating of 20, according to the EPA.
What is unclear at this point is just how much gas prices will figure into the equation for truck shoppers.
August gas prices were at their lowest level in four years, according to Jessica Caldwell, an Edmunds senior analyst.
"Stable gas prices go a long way toward making trucks and SUVs more attractive to shoppers," Caldwell said. "And if history is any indication, shoppers can expect gas prices to fall even more through the end of the year."
The AAA Daily Fuel Gauge Report on Thursday pegged the average price for a gallon of unleaded gasoline at $3.43 versus $3.58 a year ago.
Edmunds says: Truck shoppers who are concerned about gas prices should like what they see with the latest stats on the 2015 Chevrolet Colorado and GMC Canyon.
