You can find this information:
* On the Chevrolet website: Go to the Chevrolet website and select "Colorado," then choose the year and trim level. The horsepower will be listed in the specifications.
* In your owner's manual: If you own a Colorado, the horsepower is specified in your owner's manual.
* On automotive websites: Sites like Edmunds, Kelley Blue Book (KBB), and Car and Driver provide detailed specifications for various vehicle models and years.
Without knowing the specific year and trim, I cannot give you a precise horsepower figure.
