Different approaches in different countries. UK currently has a single national queue, which will shortly split into queues for V6 FE, i4 FE and own spec due to timing differences.
US is based on allocations to individual dealers out of a national allocation for 2022, then it's for each dealer to decide how they do their queue (most will be in date of deposit order). I think Canada is the same.
We don't know yet how the orders for different countries will be interleaved. But it's safe to assume all we follow the V6 FE, i4 FE, own spec sequence. I also know that first US deliveries were due to start 2-3 months after first UK ones, but that may change. The other factor is logistics, as Lotus will want to ship in batches and then those will have to be moved from port to dealers. Will the batches be by dealer, state, region or some other factor?
UK is being prioritised at the moment because UK V6 FE deliveries will be first, so Lotus need that part of the queue firmed up first. That also fits with UK dealer roadshows starting next week until early Nov. US roadshows aren't until Nov so it's very likely US customers won't have to decide V6/i4/FE/own-spec until Nov/Dec/Jan. But you'll have US pricing in the next two weeks.
