Art installation moves 100,000 toy cars an hour

IT'S NO PICASSO, but this installation by conceptual artist Chris Burden certainly has the potential to be moving. Called Metropolis II, this amazing construction took Chris and his chief engineer four years to design and create and expands significantly on Metropolis I - the latest version has 18 roadways including one six-lane carriageway. It also has a rail network with HO-scale model trains, and running at capacity it pumps 100,000 cars around its network at a scale speed of 230mph.

Audi A3 Sportback e-tron price and specs – costs £34,950

Audi A3 Sportback e-tron (pictured) costs £34,950 If governments are going to base car taxation on Co2 emissions, then car makers are going to build cars that ‘game’ the official tests. A perfect example of which is the new Audi A3 Sportback e-tron plug-in hybrid. It’s expensive at £34,950 (although the government bribe for plug-ins does drop the price you pay to £29,950), but thanks to its ‘up to 31 miles’ range on battery power only it comes complete with official economy of 176.6 mpg and emissions of 37g/km.

Pontiac Vibe

One week after Toyota introduced its new Matrix at the SEMA show in Las Vegas, Pontiac presented the new redesigned Vibe at the LA Auto Show, a five-door hatchback short wagon that - like the Matrix - is derived from a lengthened and widened Corolla platform. Clear brand differentiation between the two cars is done through the styling of the Vibe's excusive sheet metal and different interior finishes and trim. To better relate the Vibe to the Pontiac Solstice or G8, designers wanted to express more muscle and leave behind last generation's "mini-SUV" look.
