2015 Chevrolet Colorado: Performance Tested
January 14, 2015
We bought our 2015 Chevrolet Colorado just over two months ago, and it is quietly racking up miles as a suitable highway companion. It's perfectly stable on the road even as it approaches its towing limit, which we experienced when we hooked up a trailer and a 2014 Mercedes-Benz B-Class Electric Drive. We even tested the Colorado's acceleration while fully loaded. But how would this midsize truck perform without a car weighing it down?
The off-road-oriented Goodyear Wrangler All-Terrain Adventure tires wouldn't be happy about it, but it was time to gather the Colorado's performance numbers at our test track.

Acceleration comments: The best way to make the Colorado accelerate is to simply take your foot off the brake and floor the throttle in "Drive." Other techniques, including power braking (brake/throttle overlap) result in wheelspin with the traction control off, which only hurts acceleration in the Colorado. The V6 sounds coarse at high rpm but it likes to rev, which is uncommon in truck engines. Work it hard and you'll hear it plenty.
Braking comments: Though its brake pedal is initially very firm and confident (as it is in everyday driving) the Colorado's brakes faded substantially in three 60-0 runs. The third run was 15-feet longer than the first and there was substantial pedal fade.
Slalom: This is a well-mannered truck, but it's still a truck. Being narrower than full-size trucks helps it weave through the cones more easily, too. Transitions are competent and there's a decent sense of what's going on, though the steering feel could be better. Even so, for a truck, this is a pretty good one.
Skid Pad: There's little to be learned on the skid pad in most trucks and that's the case with the Colorado. It doesn't like extended steady-state cornering. Once the limit of the front tires is reached the stability control system reigns in understeer by trimming throttle.
