Had BMW revealed its new XM Concept on 1st April, rather than 1st December, I would have dismissed this challengingly-styled SUV as one of BMW’s amusing annual April Fool’s Day jokes with a daring design inevitably incorporating the traditional ‘double kidney’ BMW corporate grille. With its execution of the XM’s grille taken to a whole new, totally OTT, level though, it seems like BMW’s design team have stuck a large carbuncle on the end of an otherwise attractive person’s nose.
