And the RS.17 might have Y-shaped lower front whishbones like Merc, Ferrari, RB etc.
But what sort of CF casing are we talking about? are the Ferrari and Merc real carbon-fibre casings? is their CF outer shell that surrounds the titanium internal casing thick enough so you can deignate it as the main Gbox casing? what about the RBR Gbox?"Enstone has used a titanium casing for many years, along with Xtrac internals, but looking to the future it is clear that Chester and his team are contemplating adopting a composite casing in 2017, though they have yet to fully commit to it. ‘I think there are pros and cons to using a cast titanium ’box. The structure works quite well, but then some people have done very nice carbon fibre cases which could give a bit more freedom on suspension pickups, for example. But if you have a relationship with a good casting firm and a good machining firm then its straightforward – you design it and it gets made. With a carbon gearbox you have to develop all the processes to laminate it, manufacture it, work out the bulkheads – it is quite a big engineering exercise. While it works well for some teams this is not a trivial process. For 2017 it will be a totally new gearbox, a new concept, but it is a bit early to reveal much more than that now."
"A lot of teams have gone for the narrow span front wishbone. Its’ an interesting area to look at. We are looking at the front and we know there is a gain to be had in terms of aero profiles. At the rear there are always things we can do to make the car ride better, too."
