Skoda at the Paris motor show 2008
Thu, 02 Oct 2008By Ben Whitworth Motor Shows 02 October 2008 17:33 Skoda launched its revised Octavia at the Paris motor show – and it's clear to see they've injected some mini-Superb DNA. And that was about it for the Czech marque this year; 2008 is a bit of a slow period for Skoda, before the product onslaught begins in earnest next year. With its new nose and tail bringing it into line with the new Superb, the Skoda Octavia now has much needed visual presence.
Jaguar XK 5.0 Portfolio Convertible Review – Richard Madeley
Tue, 29 Sep 2009Richard Madeley spends a week with Jaguar's XK Convertible I’ve always held a torch for Jaguars; forgave them their trespasses even back in the bad old 1970s; loved them as things of beauty even when they weren’t. Whatever the model, whatever the year, they were Jaguars, and that was that. A bit like the Beatles’ White Album – a classic, for all the obvious flaws that only a crashing bore would draw attention to.
Renault Ondelios concept (2008): first photos and video
Wed, 10 Sep 2008By Nick Eaton First Official Pictures 10 September 2008 15:30 The Ondelios has been designed to provide a serene travelling experience, says Renault. The body has been designed to look like a singular smooth shape, so the glass appears to merge seamlessly with the body panels. Renault also claims the Ondelios's shape enhances the car’s other raison-d’etre: streamlined efficiency (and hence eco-friendliness). Those huge 23-inch aluminium alloys are designed to prevent turbulence and the car has been engineered to be a slippery as possible, boasting a drag coefficient of 0.29Cd.
