A family of new V6 engines and a completely redesigned front end highlight the big changes for the 2006 Chevrolet Monte Carlo. The standard 3.5-liter V6 engine delivers 211 horsepower with the larger 3.9-liter producing 242 horsepower thanks to bigger displacement combined with variable timing and variable intake technology. Other changes for 2006 include a re-styling of the rear fascia, an updated interior, and an upgraded suspension.
