If you upgrade the 2014 919 to progress through Endurance Kings then is highly probable, in my opinion, that such upgrades will be both necessary and sufficient to progress equally far through the forthcoming 2014 season in motorsports.

I'm just guessing mind, but it's based on I think I remember happening when the 2017 RSR moved from Porsche vs. Aston to the 2017 season in motorsports.
