One hour of flight time, a top speed of 100 km/h (62 mph), a payload of 5 kg (11 lb) – these are big figures for a drone, and figures that are basically out of reach using today's LiPo battery technology. But German startup Yeair! believes it's possible using a hybrid system in which each rotor is driven by two motors – an electric, and a two-stroke 10cc gasoline engine. And the Yeair! team has its sights set on something even more impressive down the track – personal flight in a two-seater hybrid octocopter. The quadcopter of the future, according to German startup Yeair!, will eclipse the performance of current quads by using the fuel of the future… Gasoline. Wait, what?
A couple of years ago, UK-based product designer Witek Mielniczek turned to Kickstarter to fund B – a combination radio-controlled car and quadcopter.
Its ability to both fly through the air and drive along the ground was
certainly intriguing, although its ability to traverse rough terrain
wasn't necessarily phenomenal. That's why he's now created B-Unstoppable, which swaps wheels for neoprene tank-like treads.
For a very long time, the BMW 3 Series was the car to beat in the market for premium compact sedans. Recently the competition has caught up, with the likes of the Mercedes C-Class and the sharply styled Lexus IS encroaching on BMW's turf. To try and elevate the 3 Series above its rivals, BMW has given the car a styling refresh and introduced a three-cylinder motor and plug-in hybrid option.
