Mercedes E63 AMG (2011) gets twin-turbo V8

Mercedes has updated the E63 AMG super saloon with a range of minor tweaks, and one major one. Say goodbye to the 6.2-litre naturally-aspirated V8 engine which heralded the '63' badging, and hello to another downsized, forced-induction response to tightening emissions and economy requirements. The 2011 E63 receives the twin-turbo 5.5-litre V8 engine first seen in the S63 AMG, and now powering the CL63 and CLS63 as well. So the Mercedes E63 AMG is actually an E55 AMG?

2012 Mercedes S Class to spawn a convertible

The n2012 Mercedes S Class will lose its top It’s probably a sign of increasing decrepitude as it seems only five minutes since Mercedes launched the current S Class, but already we’re talking about the 2012 Mercedes S Class – and it’s only a year away. As has always been the case with a new S-Class we can look forward to a raft of new innovations when the new S Class launches late next year; clever stuff that will eventually filter down to the cars of lesser mortals as the technology matures and the cost falls. And that clever stuff will be packaged up in a big saloon car – the normal S-Class – an even bigger car – the LWB S-Class – and a huge two door coupe – the Mercedes CL, which is expected to be renamed the S-Class Coupe when the new S-Class launches.

Mercedes-Benz prototypes spotted

Modern technology makes it harder for automakers to hide their upcoming products from prying eyes. Take, for example, these images sent to us from Autoweek subscriber Jonathan Peters while he was in Utah. Peters speculates that what he saw was a gathering of a varied Mercedes-Benz cars being tested, along with cars from other carmakers for comparisons.
