AMG FINALLY ups the ante by ditching the supercharger and developing its very own V8 that rates up there with the BMW M-power engines for performance and efficiency. Furthermore, the wholly Mercedes-Benz owned tuner no longer just ‘enhances’ – it is now right there from the design outset, to ensure that the AMG DNA is infused in all relevant future Mercedes models. After sampling the CLS63 AMG, among others, we believe that even the 2009 Porsche Panamera four-door ‘sedan’ will have some very stiff competition.
