2017 Chevrolet Colorado, The new Transmission with eight-speed auto, replacing a six-speed, weighs about the same as its predecessor but features a wider 7.0 overall gear ratio spread. Chevrolet says this results in a numerically higher first gear ratio, helping drivers start off the line more easily while carrying heavy loads. Lower rear axle ratios on the transmission should reduce engine rpm on the highway and improve fuel economy, the automaker said.
With its new transmission, the 2017 Chevrolet Colorado further differentiates itself from its competitors. The Toyota Tacoma, Honda Ridgeline, and Nissan Frontier offer no more than six gears. But Chevrolet has also made another change to the Colorado: a new and improved V-6. It now puts out 308 hp and 275 lb-ft of torque, up 3 hp and 6 lb-ft from the previous model. Revised direct injection, updated variable valve timing, and new cylinder deactivation technology make up the engine improvements.
No changes are in store for the Colorado’s base 2.5-liter four-cylinder engine or for its 2.8-liter turbo-diesel four that’s optional on certain models. But there are a few other minor tweaks for the 2017 Colorado. A four-wheel-drive selector knob with 2WD, Auto 4WD, 4Hi, and 4Lo modes is now standard on all 4WD-equipped models (it was previously only offered on the off-road-oriented Z71 trim level). Chevrolet’s Teen Driver mode, which is being propagated across the lineup, is now optional, and heated seats are no longer restricted to leather-equipped trucks.
The fully redesigned Chevrolet Colorado debuted for the 2015 model year. For 2016, it received a new engine option: a 2.8-liter turbodiesel inline-four. It also offers a standard gasoline 2.5-liter inline-four engine with 200 hp and 191 lb-ft of torque. For 2016, the four-cylinder topped out at 20/27 mpg city/highway, while the 3.6-liter V-6 gas engine was rated at 18/26 mpg. The turbodiesel model hit 22/31 mpg. General Motors hasn’t made any announcement yet about the GMC Canyon, but we imagine it will offer a similar set of updates.
We’ll have to wait a bit longer for official pricing on the updated Colorado, along with those official EPA fuel-economy numbers. As before, the V-6 should be optional on most extended-cab models (it cost $950 to $1235 extra on the 2016 model) and standard on 4WD crew cab models and all crew cab long-box models. As for the Colorado’s slightly more upscale twin, the GMC Canyon, we expect that truck to add this new engine soon as well.
