Who’s in charge?

Your BMW 530i/530d/530e test in the September issue helped answer a question I have been wondering about for ages: which gives best real-world economy? I am a company car driver, and my company’s new rules have prompted most of my colleagues to take the PHEV route. My view, however, is that the PHEV figures are a sham because they don’t take into account the mpg and CO2 produced when the car is not charged at the mains. Your third leg showed the PHEV to have the worst mpg when not charged and I would bet the PHEV also has the highest real-world CO2 emissions (down to the extra weight of the battery etc). Simon Greig
