Aye there’s plenty to go at, and will be even more going forward now that the Sigma engine is no-more.
ETA: What Personally kept me to the “official” ladder was twofold. 1) I wanted to build a brand new kit car as part of this experience, and 2) having the reassurance that I was racing against a field of rookies was important to me. If you drop into 135 Sigma Caterham Graduates for instance, you can save a shed load of money by starting with a used car - but you could be in there with people who are on their tenth season as far as I know!
From what we’ve been told, next year’s Academy will be small capacity turbo engines, so will then launch a new “ladder”, but they’ll retain the existing Sigma ladders for as long as they can maintain the grids - so I’ll still get to upgrade mine to Roadsport, 270, 310, etc. There will then be a parallel ladder of Turbo cars which will gradually roll out as next years’ Academy progresses.
It really is an impressive operation that Caterham are running. Watching Darren and the technical team at the Brands weekend was great. Although unfortunate for the drivers, they repaired a couple of shunts and I think swapped three gearboxes over the weekend. The drivers typically only missing a session at the most…!
Be interesting to see how that operation scales this weekend as we have Academy, Roadsports, 270 and 310 all in the same paddock!
