Videos: Volkswagen's exterior and interior designers highlight the Up's design elements

We've enjoyed the design of Volkswagen's new Up since we first saw the vehicle in concept form at the 2007 Frankfurt motor show. Devoid of any extraneous detailing, the simple, product design aesthetic is pared back to represent the crux of VW's design philosophy: pure, simple and solid.  The result is a harmonious design that stands out from the pack, with simple surfacing and subtle detailing; the Up's design is pure and minimalistic, which serves to exude quality in the product. Inside, the vehicle is brimming with space-saving design details.  From an IP devoid of central air vents to a thin headrest that visually extends the height of the interior, the Up is a success story in space efficiency, but it is also finished to a high level using quality materials.

Lexus IS 300h promises unrivalled ownership costs

The new Lexus IS - launched at Detroit in January and costing from £26,495 for the IS 250 in the UK – actually offers ownership costs that eclipse diesel offerings from the likes of Jaguar, BMW, Audi and Mercedes, say Lexus. Despite the logical assumption that the complex hybrid powerplant in the IS 300h would cost more to maintain, Lexus say the opposite is true. Because it has no clutch and the starter motor and alternator are integrated they require no servicing or replacement and Lexus has fitted a timing chain instead of a timing belt, so it won’t need regular replacement either.

Mercedes SLS AMG Roadster revealed ahead of Frankfurt

But you’d be wrong. Those photos were in fact of a disguised SLS Roadster (although you’d have to look hard to see what was hidden).
