Audi shows S3 Sportback (2013) – but is a used S3 a better buy?

Here’s Audi’s S3 Sportback, the five-door version of the 296bhp Quattro hot hatch unveiled last year. The S3 Sportback takes 5sec flat to accelerate from 0 to 62mph, that’s one-tenth of a second quicker than Audi’s official figure for its three-door stablemate. That’s because the initial 5.1sec S3 time was only an estimate, and Audi’s subsequent tests have shown the three-door S3 actually dipping below five seconds in the 0-62mph sprint.

Mercedes S-Class AMG Sport Edition – it’s another S-Class run-out special

The Mercedes S-Class AMG Sport Edition is another ‘final’ S Class model with extra equipment as the W221 comes to the end of its shelf life. The current Mercedes S-Class (W221) has been with us since 2006, despite which it’s still a fine car (and a great secondhand buy), but it’s about to be replaced by an all new S-Class. That’s why S-Class sales are falling and why Mercedes has rolled out the S-Class Grand Edition and CL Grand Edition to persuade buyers that a new S-Class (or S-Class coupe, in the case of the CL) is still a good place to park a sizeable chunk of change.

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?
