MG5

The MG5 is a C-segment, two-box hatchback, based on SAIC AP platform. Like the MG5 concept, SAIC Design UK and SAIC Design China designed the production version's exterior and interior respectively, in a collaboration between Ken Ma – former director of SAIC Design China – and current Global Design Director Tony Williams. In general, its exterior has inherited the ‘Flow Edge' design philosophy from MG3, which launched in the Chinese market last year.

This is the new Audi S1

Audi has turned its limited-production Audi A1 Quattro into a full series-production model with the three-door S1 and five-door S1 Sportback.

Audi says the S1 and S1 Sportback won't be sold in the U.S.

Concept Car of the Week: Porsche Tapiro (1970)

By the late 1960s it was time for Porsche to create a new car that would replace its ageing entry-level model, the 912. Its sister company Volkswagen also needed a sports coupe to replace the Karmann Ghia and so the two brands joined together to develop what would become the Porsche 914. These days the 914 holds something of a ‘cool factor', generally considered as the ‘black sheep' in Porsche history.
