<p style=”text-align: left;”>Probably cheaper to heat, especially with seats and wheel on – as long as you are not going anywhere – for many cost of fuel and EV charging will be the same.</p>
As for winter EV mileage – it will be a new learning curve and information to share – so lights and windscreen wipers on full – heated seats and wheel (ultimate) will all need to be assessed to find the sweet spot for comfort and range – long journeys will need more compromise – I would hope for 4.2 plus – so 270 plus – time will tell.
Once again the pool of knowledge and experience will be a valuable resource!!
