I don’t believe that the all new X2 has ever been on the scheme. I might be wrong, but I thought that when the X2 was last on it was the previous model (bearing in mind that the new X2 has only been out a matter of months, much later than the new X1).
The all new iX1 and iX2 appeared fairly quickly, but we haven’t been offered any petrol, diesel or PHEV versions of the X1 or X2 yet.
I’d jump at an X1 petrol, but don’t think it will appear given Motability’s fixation on EVs and PHEVs. I think that the PHEV is the best we can probably hope for. Same with the X2.
