From 2005 through 2009 Chevy produced a mid-sized SUV known as the Trailblazer. The Chevy Trailblazer comes with several engine options, the base model being a 4.2-liter, in-line six-cylinder Vortec engine.
The 4.2-liter had double overhead cams and utilized variable cam phasing. It had four valves per cylinder, making the total valve count 24. The Vortec had a cylinder bore of 3.66 inches and a stroke of 4.01 inches; this produced an overall displacement of 256 cubic inches. It also had a compression ratio of 10.1 to 1. The block of this Vortec engine was made from cast iron.
This 4.2-liter in the Chevy Trailblazer produced 275 ft-lbs. of torque at 3,800 rpm. This is a significant advantage over the Jeep Grand Cherokee and the Dodge Durango’s 235 ft-lbs. at 4,000 rpm. It also has a slight advantage over the Ford Explorer V-6, which produced 254 ft-lbs of torque at 3,700 rpm. These torque numbers pushed the Trailblazer’s maximum towing capacity to 6,300 lbs.
