50mpg from brakes?

All of the talk about perpetual motion and extremely high gas mileage reminds me of an article I read quite a few years ago. A group of college students built a gas powered vehicle that would get around 50mpg (to the best of my recollection) and had good acceleration from a stop. They used an accumulator to store hydraulic energy from braking to assist starting acceleration. I think they were using a pump to pump oil from a reservior to the accumulator to provide braking force. Then on acceleration the pressurized oil might have been routed to the transmission. I don't remember all the details anymore. I looked around on the web for a few seconds and found that there is some development in this technology. Is this feasible technology?
