Much of the research was drawn from Erling Holden, who wrote this book – Achieving Sustainable Mobility.
His research found that while petrol engines were the worst performers in terms of carbon emissions and fuel efficiency, petrol-electric hybrids were almost as bad.
It was interesting stuff.
We’ve not read this one, but were honoured that Erling contacted us to tell us about his new book, available on Amazon.
Good work, chief.
