Shanghai Auto, the Chinese automaker that's refashioning the Rover 75 as the Roewe 750, says it's building a version that uses an "integrated loop" to garner a 20% increase in fuel efficiency. The boys at China Car Times say that's likely code for a hybrid system. But if our lack of an electrical engineering degree has taught us anything, its that an integrated loop could mean a variety of technologies at work, from some manner of digital controller to a box of animal crackers made into a bong. We'll just have to watch this one carefully.
