Volvo Group plans wirelessly charged bus line

There's one bit of futuristic transportation technology that seems to get trotted out almost as often as autonomous cars, electric cars and flying cars: Inductive, or wireless, charging for city buses. It's not as sexy or as memorable as the perpetually out-of-reach commuter-grade Harrier jet, but it uses proven technology (GM's EV-1 uses inductive charging, as do electric toothbrushes) to save or eliminate fuel and to reduce emissions. And unlike the flying car, induction-charged buses are hardly fantasy: They've been used in European cities for over a decade, South Korea started testing a fleet last year and Utah got in on the act recently.

Citroen DS3 hits 200,000

The upmarket Citroen C3 – the very appealing Citroen DS3 – has hit the 200,000 production mark this week, a little over 2 years from launch. But we had to do a complete volte face when we finally had the new Citroen DS3 in for review – it’s an absolute cracker. In fact, so impressed were we with the DS3, we thought it probably the best car we’d had in during 2010, something Top Gear ended up agreeing with us on when they made it their car of 2010.

Mazda Kiyora concept

Mazda has released these images of the Kiyora compact urban concept car the automaker will reveal at the 2008 Paris Motor Show. Based on an all-new platform designed to maximize weight reduction, the Kiyora is claimed to represent the harmony between driving pleasure and environmental and safety features. Meaning 'clean and pure' in Japanese, the concept of 'Kiyora' helped the designers to imagine a city car cutting cleanly through an urban landscape, with water as the design theme.
