The Model 3 Long Range has an official range of 348 miles (WLTP). While you're right that this will probably drop over winter and with a lot of high-speed motorway driving, I'd have thought your trip would be doable on a charge if you take it fairly easy. Tesla's Supercharger network is excellent, if you do need a quick top-up away from home. PHEVs aren't great for motorway driving - they only have a short electric range and can be thirsty once the battery's empty.
