Robert Llewellyn tested the BMW i8 for over 1,000 miles on a journey in the UK achieving average fuel economy of 52 mpg.

58 mpg in eco mode, and over 36 mpg in sport mode was enough to call i8 an economical sports car.

As always, it's very entertaining episode of Fully Charged.

"The first plug in hybrid electric supercar on Fully Charged. Not sure if that's true but it sounds good, in fact if you like that sort of thing it sounds amazing.

Over 1,000 miles of driving, average of 52 mpg. A very fast, semi economical sports car."
