Elon Musk unveils Hyperloop

Elon Musk has been teasing us with something called the Hyperloop for a while now, referring to some Goldbergian cross between a railgun and an air hockey table that would zoot us and scoot us from San Francisco to Los Angeles in a half-hour. Now, in a 57-page PDF available here or here, he's outlined just what Hyperloop could be. Bad news?

BMW Concept5 X5 eDrive revealed. It’s a plug-in Hybrid X5

The BMW Concept5 X5 eDrive (pictured) will debut at Frankfurt The arrival of the BMW Concept X5 eDrive ahead of its debut at Frankfurt next month doesn’t preview and immediate addition to the X5 range of a plug-in hybrid, but it does show what will be on offer in a year or two. Just like yesterday’s Mercedes S500 plug-in hybrid, the X5 eDrive is another example of how car makers have developed their way round CO2 taxation levels by throwing electric motors at ICE engines to create a car that offers impressive emissions and economy on official tests. In the case of the X5 eDrive that means a four-cylinder twin power ICE engine (BMW aren’t saying, but we’re assuming its a petrol engine), a 94bhp electric motor and a lithium-ion battery under the boot all working together to produce an X5 that is capable (at least in official tests, which is all that matters) of 74.3mpg and emissions under 90g/km.

Audi lights up for the shortest day

AUDI UK has created a stunning series of low-light photos to celebrate its success this year, just in time for the shortest day of the year. The seven photos use a technique called ‘light painting’, where a stationary object in the dark is lit up by a small hand-held light to selectively brighten areas over a long exposure period to eventually create an unusual-looking end result. To the trained eye it looks like Audi has supplemented the photographer’s torch with static lighting to increase the beauty of the end result, but there’s no doubting their success.
