Nice to hear that. That is first time at Enston to introduce carbon fibre gearbox.
They've built CF G-boxes before (last one was 2009 AFAIR) but this might be the first G-box with a CF outer shell and a metal* 'cassette' inside.
Franco Nugnes says it's alluminium but AFAIK Enstone uses titanium since 2010.
RacecarEngineering April 2017:
"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."
Edit: 2017 gearbox doesnt look to be a "a totally new gearbox, a new concept" compared do its predecessors...
