Recumbents and all feet forward machines

Alright so for engineering studies, my school is taking part in an EV challenge. Basically, we have to build an electric powered car. The school has provided a hub motor on what I believe is a 700c wheel.
My task is to build the chassis of the car, seeing as we only have a single propulsion system we have to settle on a tricycle design. The hub motor will be at the back with two wheels at the front for steering. (no, we can't build a bicycle). I want to build the chassis as a leaning tricycle, in that the tricycle 'leans' into the turn. In personal theory I believe that this will increase manouverability as well as cornering ability as the tyres will have more 'compliant' forces working upon them rather then being 'pulled' around the corners.
I'm looking for plans or schematics of any sort which clearly show the 'leaning' mechanism. I've a couple of ideas which I think will work but believe that they will be over powered by centrifugal force around a corner and rather lean outwards which in turn would roll the car.

Many people feel their lifestyle has a high price, but they're quite cool with that .. as long as somebody ELSE pays the price.
You say you are building a electric vehicle but If you don't have to build the motor do you? then why do you need to reinvent the chassis, where does creation start?? Will you be expected to build all the other components(brakes/levers, shifters/derailuers etc)? Or will you simply buy them from tested manufacturers? Not to dampen your enthusiasm but your effort might be better used by simply selecting all equpment(including a chassis) and packaging it all neatly in to a finished product, you'll probably need to design a shell, it would require customising. Save your time, why reinvent the wheel motor so to speak
