New concept cars hit the auto world

Since the North American International Auto Show is regarded as one of the world's best automotive shows, it's no surprise that the automotives on display at the event (open to the public January 14-22) appear keen to spread their wings. Here is a roundup of the best concepts to see at the event, currently taking place in Detroit.motoring Smart For-Us Unarguably one of the most fun concepts, this all-electric model explores how the tiny Smart could one day evolve into a pick-up truck, albeit on a small scale. Capable of carrying two passengers, the vehicle can also hold and charge two Smart e-Bikes in its haulage area.

Toyota NS4
Toyota chose to look beyond the Prius with this concept, a hint at what we'll see from the Japanese brand within the next five years. Aerodynamic and full of high-tech wizardry, the NS4 proves that Toyota is in the eco-game for the long run.

Volkswagen E-Bugster
With Volkswagen giving its new Beetle a 21st century overhaul, complete with electric drivetrain and a lowered form, this car is both vintage and modern.

Nissan Pathfinder
The Pathfinder has been revamped, with a new platform likely to hit production later this year.

Volvo XC60
It's an interesting effort by Volvo XC60, with a 45 mile (70 km) range before the engine kicks in and a four-wheel drive.
