CCS/GM E-Flex project

Cadillac V-Flex Evan Mai Evan Mai presented the Cadillac V-Flex, a mid-engine electric race car that uses GM's E-Flex platform in a new configuration and advances Cadillac's art & science design language.  The race inspired proportion and layout of the V-Flex draws heavily from Le Mans prototype and F1 cars. Power would come from an electric motor with a range extending internal combustion engine. The Li-ion battery placed in the bottom center of the vehicle could be swapped from underneath the car during pit stops. Aluminum heat sinks in the rear efficiently dissipate heat away from the motor and battery while performing as a rear spoiler.  The front grille serves to communicate the Cadillac design philosophy and also serves as a functional aerodynamic enhancement.

Audi TT Roadster

Following the launch of the new TT earlier this year comes its open sibling, the TT Roadster. Continuing to rebuke the trend for folding hard-tops despite even Mazda providing such an option on the MX-5, the TT Roadster perseveres with a cloth roof instead. Not only saving weight, this also means no visual mass protruding over the belt-line, though like its predecessor the roof adopts a more abrupt profile when raised than the fluidity of the coupe's profile.

Porsche seeks ‘everyday magic' with film contest

Porsche North America has tapped into its considerable fan base, seeking homegrown visions for its My Daily Magic filmmaking contest.

One film shows a father that has to run some errands on a weekday.
