Drive the Colorado for a bit, and three things keep popping into the ‘what’s different about this particular pick-up truck?’ listing. First off, the upsized engine – a 3.5-liter five-cylinder producing 220 horsepower at 5600 rpm and 225 pounds-feet of peak torque at 2800 rpm – is not a V6 or V8. A pick-up without a V6 or V8 option is uncommon if not outright rare. In this vehicle application, though, a five-cylinder is adequate. But that’s not to say the engine is performance perfect; more acceleration power at lower speeds would be appreciated. (Base Colorado engine is a 2.8-liter 4-cylinder the produces 175 horsepower at 5600 rpm and 185 pounds-feet peak torque at 2800 rpm.) As for the two other often noticed points about the Colorado? The answer is seats and space. Undesirable seat foam effectively makes riding for any distance an uncomfortable pastime. So even though sitting for a long amount of time in this vehicle burns the bottom, the spacious cabin – lots of headroom and legroom – scores big bonus points. The regular cab 4WD Colorado LS sports such standard equipment as power rack and pinion steering, independent front suspension, two-stage rear leaf springs, 4 wheel anti-lock brakes, fog lamps, 2-position locking tailgate, air conditioning, AM/FM stereo with CD/MP3 player, and tachometer. Colorado LS with 5-cylinder engine and optional four-speed automatic transmission has mile per gallon estimates of 18 city/22 highway. MSRP is $21,255.
