A Ford-funded study by the University of Michigan has examined the environmental credentials of electric VTOL aircraft for commuting, compared to both regular and electric cars over a range of commuting distances. The results paint an interesting picture of future mobility.
-
British company Camcon Automotive has built a fully digital engine valve system, uncoupled from the crank, that offers unprecedented control over the combustion cycle. It enables some weird and wonderful ideas we've never seen before, such as giving 4-stroke engines brief 2-stroke power boosts.

Amid tightening emissions regulations, car makers are looking for new, unique ways to make their engines more efficient. Volkswagen has used this year's Vienna Motor Symposium to unveil a range of new tips and tricks aimed at eking better mileage out of petrol, hybrid and electric powertrains alike.
