From the RCZONE DHI cup report
We've had a closer look at the Corally PHi prototype which is in action here at the DHI Cup, Marc Fischer, Jonas Kaerup, Federico Sala, Simo and Sakke Ahoniemi all drive the PHi, the latest touring car coming from Corally and to be released in early 2007. The car featured on the pictures is the prototype, the final version will be a bit different, parts will of course be refined. Noticeably different will be the rear to in blocks, the prototype uses shims, same as seen on the old car, whereas the final version will use blocks in different sizes, it will make it simpler and of course stronger as well. Working on the final version will be considerably easier, the prototype features many parts which are screwed together, these parts will be made in one piece.
The dampers will be all new in order to fit the lower shock towers, the shocks will be specifically designed for this changed setup and lower cg. The steering system will feature a larger possibilty for adjustments to the ackermann. Looking towards the rear of the car, a new differential which is a bit similar to what we know from 1/12 scale where 3 ball bearings are used, gone is the pain of working on setting up a traditional touring car type differential. The spool will be a new type as well and the ball bearings used for the spool and differential will have the same size, no need for changing any longer, loosen two screws and cange, that's it. The prototype features a permanent internal gearing, like all other touring cars, but the final version will incorporate the possibility of changing internal gearing to suit the different needs of racing types, ie modified benefits from one whereas spec and stock classes from others. There's a lot of new features built in to the new PHi, it's not just a revamp of the old version, but an evolution
It sounds like more parts are new then it appears in the photos.
