The ILMC calendar for 2011 included some events that combined with LMS races. The LMS declined to further that arrangment for 2012 as they were having to turn away one-off LMS entrants to squeeze the ILMC and LMS cars onto the grids at all three (Silverstone, Spa and Imola). So any round the LMS plans to use next year cannot appear on the WEC calendar.
Sebring doesn’t have that problem but Petit Le Mans does (it had to organise a qualifying round for LMPC and GTC runners and this caused a fair bit of dissatisfaction with the fanbase). Hence WEC is trialling sharing Sebring, and only Sebring, with ALMS this year. There is some indication that WEC, in the long run, wants to run the American round – wherever it is – on its own, so that it can have full control over the regulations at all of its rounds. What effect this has on ALMS is unclear.
Nonetheless, scheduling any WEC event to clash with Petit Le Mans is stupid, since it’s the second-biggest sportscar race in the world. Could WEC not have delayed the Asian rounds for two weeks to enable both races to get attention? As it stands, most people will ignore the Bahrain round in favour of PLM, except to decry the whole idea. Going to a race for reasons that appear to be due to another series’ difficulties is bad enough as it is (why not Dubai, Abu Dhabi or Qatar?)…
10 races strikes me as too many. The teams need to be able to afford getting around the world and also to repair their cars after crashes (sometimes it can take weeks, especially if a write-off is involved). It would lead to teams having to miss rounds because suppliers haven’t been able to give them components in time.
