2008 Mercedes-Benz S-class
Mercedes' flagship sedan has been well received since it went on sale about a year ago, so not much has changed for 2008. There is a new V-8 model available, the 518-hp S63 AMG, which joins the S550 and the V-12-powered S600 and S65 AMG.
The S550 4MATIC also gets a new, more efficient version of the 4MATIC all-wheel drive system to help reduce weight and fuel consumption.
