A bit more seriously, Jag is the smaller part of JLR.
If Jag sells a few high end electric cars with big margin, that lessens the overall JLR carbon emissions number, which allows the big selling Range Rover and derivatives to continue with their Ingenium inline 6s - or hybrid and electric versions.
Of the F-Pace/Velar twins, I believe most of the customers bought the Velar -which is a pity because the F-Pace nailed the handling SUV brief after the update - some great twisty mountain road footage here
