BMW 4 Series Gran Coupe (2015) revealed in patent pics

The BMW 4 Series Gran 4 Coupe is proof that BMW is continuing its efforts to fill every imaginable niche. It's a four-door version of the 4 Series coupe, which itself is based on the 3 Series saloon, and adds to a bewildering array of machines stemming from the F30 3 Series. Officially the 4 Series Gran Coupe, revealed in full in these images from the firm’s design patent, is given the ‘F36’ codename and is expected to be officially unveiled in early 2014. It joins the F30 (3 Series saloon), F31 (3 Series Touring), F32 (4 Series Coupe), F33 (4 Series Convertible), F34 (3 Series Gran Turismo) and F35 (3 Series long-wheelbase saloon) to complete the range of body styles.

Designer Interviews: Giorgetto Giugiaro

Ask any aficionado who the greatest car designer of all time is and Giorgetto Giugiaro will be the name on most lips. Responsible for more than 200 vehicles, equating to some 60-million production cars on the road as well as dozens of concepts for the world's finest car brands – not to mention cameras for Nikon, electronic organs for Bontempi and even a type of pasta – he is without equal. Born on 7 August 1938 in Garessio, northern Italy, he started his career with Fiat in the mid-1950s, aged 17.

Mercedes-Benz CLA

This is the Mercedes-Benz CLA, the four-door sedan version of the latest C-segment A-Class although the Merc marketing department would rather we call it a 'four-door coupé'. Previewed by the Concept Style Coupé at the Beijing auto show earlier in 2012, the CLA will join a growing band of C-segment premium sedans including the new Audi A3. At around 4,600mm long it's over 300mm longer than the hatchback.
