The Chevrolet Malibu gets a few updates for 2006. Most interesting is a new performance-oriented SS trim level that features a 240-horsepower V6 engine. Chevy has also juggled the existing trim levels: the base model is now called the LS, the former LS is now the LT, and last year's LT is now the LTZ. Other minor changes include freshened front-end styling, new wheel designs, flashier trim pieces for the instrument panel, a new four-spoke steering wheel and standard child security rear door locks on every trim level.
