    Will have a 300km trip, no charger on the way,
    - Use pure EV mode until power out (SoC = 30), then have to use HV mode;
    - All HV mode for the whole trip.
    Which is more economical ?

    Use EV mode in the city and switch to HV mode on the highway. Gas motors work well on the highway and electric motors work best at lower speeds.

    Thanks. To me the 300kms are all high way, maybe only 2-3 kms local from my home to high way:)

    What about at your destination? You can blend your trip. Ideally you’ll arrive back home in HV mode with no more EV mode charge.

    if it's all highway, (and even if it isn't) you're gas and electrical costs will have a major impact on economy.
    for some, it's cheaper not to charge.

    I think I can make it fully charged at the destination city, so almost the same situation for both go and come back ways.

    Might be cheaper not to charge but I think it is always cleaner to charge!

    I am in Quebec and we are using Hydro the cleanest and recyclable electric :)
    And normally the fee of charging is 1 CAD / hour.

    I mean, will you need to drive around at the destination? If so, you can use up your EV charge there.

    If not, then I'd just use up the charge at some point during the highway drive.

    I see you live in Montréal, Québec , gas price are very high , so I suggest you start on EV mode and switch to HV at 50% SOC .Then you will have headroom for regenerative braking to recharge the battery . As an example: Laval to Baie ST Paul ,I start on pure ev getting on the 640 Est , then switch to HV when I reach the 40 Est (Repentigny) then approching Charlevoix there are alot of steep hills ,regenerative braking charges up the battery to 80% SOC when I reach Baie ST Paul..So playing with EV and HV depending on terrain will have a benefit even if there is no stopping for charging:).
    In city driving ,or heavy traffic I choose EV and for highways I choose HV with 50% SOC, also I limit my speed to 100-105KM/h on highways.

    Well yes it's not so much in Montreal area, I ordered in Feb. 2022 and was in waiting list for 1.5 years.
    The 2023 prime model started to deliver from Apr or May, 1 - 2 cars / month / dealer..... :)
