The new Mercedes-Benz CLS 63 AMG is increasingly spotted out on test ahead of launch in 2011. We've been scooping the regular C218-generation CLS for some time – and the AMG once back last autumn – but now we've seen the clearest spy photos yet of the four-door 'coupaloon'.
As we reported in 2009, the new CLS 63 will feature AMG's new 5.5-litre twin-turbocharged V8 in place of the outgoing car's naturally aspirated 6.2-litre lump. The 63 badge will remain, however, to reassure buyers that they're still buying top of the pile. How quick is the new Merc CLS 63 AMG (2011)?
It won't be short on grunt, this new engine. The 5461cc lump packs 544bhp/590lb ft in standard form, and an AMG performance pack upgrade will nick that upwards to nearer 563bhp and 663lb ft. A smaller turbo ensures instant response at low speeds while the larger blower kicks in higher up the rev range for Boeing-spec thrust on the autobahn.
The CLS family is based on E-class mechanicals, which bring a seven-speed transmission and the potential for floaty comfort and sharp handling when on back roads. Let's hope there's also a dash more style inside; the new E models are unremittingly sober inside, although the quality has climbed from the previous E-class.Talk about downsizing! From 6.2 to 5.5... what are the benefits?
Direct-injection and a dunk in cc's should cut consumption and emissions, which are claimed to fall by around a quarter in its S-class AMG application.
We'll see the new CLS 63 AMG four-door coupé/saloon mash-up at the 2010 Paris motor show. However, a new 'wagon' concept CLS is tipped for next week's Beijing motor show.
