Our 2015 BMW B47 engined F55 Mini attracts only £35 VED (although Rachel from accounts may have added a small percentage on) and is ULEZ compliant. Given our government not being likely to miss a trick speaks volumes in regard of this engines low emmisions, complying with current Euro 6 regulations. Some other diesel engined cars have attracted as little as zero VED in the UK, the same as BEV's until current tax year. I cannot see the logic of discontinuing production other than to align with current brain washing. The advantages of hybrid diesel cars would seem an unexplored avenue.
