Fisker reveals hardtop convertible Karma S concept

Alongside the production version of the Karma sedan at the Detroit Auto Show, Fisker debuted the second model to join the Karma range. The Karma S (for Sunset) concept is spawned from the same aluminum spaceframe that underpins the sedan, but loses a set of doors. A retractable hardtop covers the four-passenger interior.

Caterham Sevens reimagined as classic F1 cars

You could never really call the Caterham Seven modern – its look has remained fundamentally unchanged since the original Lotus Seven (the car Caterham would eventually buy the rights to build) launched back in 1957. Today, the engine is still in the front, those delightfully exposed front wheels still float over bumps and the frog-eyed headlights serve as a reminder of years gone by. And now the modern Seven has been taken right back to the period where it was first conceived, with these Grand Prix-style racers from Zolland Design.

Samsung SM5

Samsung Motors, the Korean subsidiary of Renault-Nissan Alliance, recently released the newly-redesigned SM5 sedan for the Korean domestic market. Based on the Nissan Teana, the SM5 is the second best-selling vehicle in Korea's D1 segment, ceding the top spot to Hyundai's Sonata. The most significant change to the exterior design is visible around the front bumper region, where the strong 'chin' (lower section of bumper volume) displays both solid and aggressive styling cues when viewed from the front.
