And here’s another change. Not so very long ago, diesel engines would have been the default choice in cars like the T-Roc. Not now, though. Volkswagen is saying that only one in five of UK-sold T-Rocs will be diesel-powered. Much of that is down to the fact that three in every four T-Roc sales will be made to private individuals, not fleets. Well, that and Dieselgate, presumably.
