Porsche 918 Spyder

Supercars generally have the reputation for being gas-guzzlers as they rage across our roads with a need for speed. But the new Porsche 918 Spyder may be about to change all that - for while it manages a top speed of 201mph, it also manages an economic 94 miles to the gallon. That makes the Porsche more economic than the car with one of the greenest reputations - the Toyota Prius - which can manage 72.4mpg.

Chinese Stealth Fighter

Flying over the skies of Chengdu in southwest China, the Chinese's latest stealth plane - the J-20 Might Dragon - is a testament to China's growing prowess in military technology.

Hovering Egg Car Volkswagen

When Volkswagen invited its customers to think up some ideas, it was perhaps inevitable that there would be at least one flying car design put forward.
