NEW DIESELS WILL COME BACK, TOO

Expect the harsh attitude from new car buyers towards diesel to soften once the penny drops that, under the new WLTP emissions regulations, the latest diesels produce cleaner real-world exhaust emissions than older petrol cars. Popular medium and large SUVS rely on frugal diesel engines to remain viable from the point of view of fuel costs and also CO2 emissions. Diesels generally will always be more economical than petrol cars or petrol hybrids for motorway users. Buyers who have switched away from diesel may find the real-world economy too compelling to not want to return to it.
