Infographic: How much clay do Ford’s design studios use each year?

Ford has offered an insight into its clay modeling processes with a series of videos and an infographic that charts the process involved in turning a designer's sketch into a full-size model. The infographic uses data taken from all of Ford's global design studios in 2012 to give an idea of how much clay is used in a year, plus how much paint and di-noc film is used to cover each model. Ford has also released a video that gives a behind-the-scenes look at the firm's clay modeling studio in Merkenich, Germany, including interviews with members of the modeling team.

Fiat 500L five-door spotted

Autoweek spotted this manufacturer-plated Fiat 500L earlier this week on the streets of suburban Detroit. With its round headlights and cheerful grille, the five-door hatchback's resemblance to its three-door cousin is apparent even under its coat of liberally applied camouflage.

Vauxhall launches new extended used car warranty

Vauxhall has launched a new extended warranty for use cars, available for cars up to 70,000 miles for one, two or three years. Two years ago, Vauxhall launched its Lifetime Warranty for new cars, spurred on by warranties from the likes of Kia and Hyundai, offering buyers long-term peace of mind – and which was actually a 100k mile warranty rather than a lifetime one, but a welcome assurance for motorists nonetheless. Now Vauxhall are extending their enhanced warranty offer to use car with the launch of an extended warranty aimed to give owners of used Vauxhall’s a similar level of cover to new car buyers.
