My vehicle is aged, however I am achieving the same range in cooler conditions.
This applies to all electric vehicles, yet it is not widely recognised that the reduction in range during winter is substantial.
As temperatures rise, the elevated range will reemerge.
Infrequent use of the petrol engine during winter months often results in the formation of 'mayonnaise' within the oil filler cap. I suggest monitoring it and maintaining regular cleanliness. The issue arises from condensation and insufficient engine operation to eliminate it.
Particularly in winter, I advise operating the petrol engine to ensure oil circulation and generate warmth within the engine. Conversely, if the petrol engine is compelled to engage at elevated RPMs while cold, it may be detrimental to its condition. Particularly if all the oil remains in the sump.
Excellent vehicles, although one must adapt to the technology and acknowledge that it is not a fully electric vehicle.
I contend that the petrol engine in a hybrid vehicle should have the oil pump operating continuously, even when the engine is inactive, and that some heat should be introduced into the cooling system to ensure readiness for operation.
I frequently contemplate the state of the petrol engine in plug-in hybrids that predominantly operate on electricity. These vehicles are not fully electric and should not be operated as such.
