Bentley's posh leather child seat

Bentley has launched a new collection of accessories to compliment its cars, all of which apparently highlight the company’s 'design and craftsmanship skills'. From child seats to torches, the range is designed to make the life of your average Bentley owner just that little bit more comfortable. Perhaps, but having spent £150,000 on 200mph of GT pleasure, you are unlikely to fit a Halfords booster seat. The hand-stitched child seat - for 'the company’s smallest enthusiasts' - is made to match mum or dad's car with the same leather and piping, and can feature the child's name embroidered on the back beneath the Bentley wings, if Sir or Madam wishes.

Audi puts a price on its 2012 V8 S Models – S6, S7 & S8

2012 Audi S8 - costs £78k Audi’s new V8 – shared with Bentley – arrives in the UK in the guise of the 2012 models of the S6, S7 & S8. Prices from £53,995 to £77,900. Audi, just as most other car makers are doing, is down-sizing its cylinder count and upping its reliance on forced induction as it seeks to cut emissions and improve fuel economy (well, official figures, anyway), which has meant the end of the 5.2 litre V10 in its ‘S’ models.

Jaguar Concept Speedboat (2012) first official pictures

Premium estates are, we're told by the marketing people, for those with outdoorsy, active lifestyles. It's small wonder so few estates are truly utilitarian load-luggers: they're Tourers or Avants, or in this case, the new Jaguar XF Sportbrake. To tie in with the car's international launch, Jaguar gave it an active outdoor accessory of its very own: an Ian Callum-designed speedboat.
