The midsize Colorado is available in several cab and bed configurations. Its smaller size makes it more maneuverable than full-size trucks in tight parking lots and streets. Unfortunately, larger trucks don't cost much more and get about the same fuel economy. The Colorado launched eight years ago with a choice of inline four or inline five-cylinder engines. The manual-equipped four-cylinder engine offers decent power and fuel mileage. The five-cylinder automatic transmission combo feels slower and suffers from an inherent vibration from the odd cylinder count. A few years ago Chevy added the 5.3-liter V-8 from the larger Silverado 1500. Unfortunately, mating the V-8 to a four-speed automatic nets it less fuel economy than the larger truck with the same engine and a six-speed automatic. The Colorado can tow up to 6000 pounds with the V-8 making it a good value for city dwellers who need its towing capacity and park in tight lots. An optional ZQ8 sport-tuned suspension lowers the truck one inch and increases handling. The Z71 off-road package for four-wheel drive versions is ideal for those who spend time off-road. An-all new Colorado is expected sometime after the summer of 2012.
