The new Mercedes CLS offers true Coupé feeling with four doors for a maximum of 5 people. The third generation of the CLS Mercedes has donated a completely new engine program. I was allowed to drive the current top model Mercedes-AMG CLS 53 4MATIC+ in Barcelona and tested the quality of the new 435 hp six-cylinder. I also talked to an expert about the technical refinements of the new CLS engines. Source: http://quickcarreview.com
