Getting in to the CLS range isn’t cheap, with the entry-level car approaching £50,000 in price, especially with options. All mainstream models wear Mercedes’ eco BlueEfficiency badges, the CLS250CDi kicking off the range, with the alternative diesel being the 350CDi. Petrol power comes from the 350 and 500 models, while the storming 517bhp 63AMG (which unsurprisingly doesn’t get a BlueEfficiency badge) tops the range (and is reviewed separately on this site).
