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.

New 2015 Mercedes S 65 AMG Coupe revealed – price from £183,065

The new 2015 Mercedes S65 AMG Coupe arrives The range-topping Mercedes S65 AMG Coupe has been revealed, and offers up its credentials as the perfect alternative to the Bentley Continental GT W12 with its 621bhp V12 delivering performance of 0-62mph in a 4.1 second whoosh. Even with its AMG badge, the S65 AMG Coupe is probably best thought of as the luxury take on the more aggressive and sporty S63 AMG Coupe – just as the V8 Continental GT is the sporty side of the Bentley Continental range – with its more effortless take on performance and power. There’s no doubt you get plenty of power and torque from the big V12, with 621 bhp and 737lb/ft of torque – driven to the back wheels through Mercedes’ seven-speed Speedshift automatic ‘box – on tap, enough to get to 62mph in 4.1 seconds and on to a 155mph limited top speed – but in a more creamy and effortless way than the S63.
