My Dealer (Maryland) informed me of the same (FE 2.0 V6 Manual delivery in April 2024) back in Aug 2023, but that was based on a Dec 2023 build, not sure if that is still the case.
If CARB is obtained in January and deliveries start , I would expect delivering 500 cars would take 2-3 months.
Once cars are delivered to North America (next wee) will they will immediately be delivered to the dealers for prep or would be stored at a central location until CARB is approved and then distributed to the dealers for prep. I presume Lotus would hold all cars at a central location until CARB approval is obtained to ensure no penalties. Maybe not.
Taking that into account, I think a FE 2.0 V6 manual delivery would be summer of 2024 (if prioritized over FE 1.0 V6 Auto). I do not see FE 1.0 or 2.0 specifically noted in dealer recap - just First Edition.
