I'm thinking of getting a PHEV and I heard an interesting story about a friend of a friend. He drives his company 330E once a week or so into London, it switches to electric at the congestion charge zone and back to petrol when he leaves. The thing is, apparently he's never charged it using the lead. So is the braking recuperation good enough over what might be a 50 mile round petrol journey to give him maybe 5 miles electric range or is he using Battery Control Mode? And how daft is it financially to use petrol to charge the battery?
