My gas guzzler is lucky to reach 320 miles, averaging about 22mpg - One British journalist has just driven from Tangiers in Africa to Goodwood in England, without stopping to re-fuel.
Andrew Frankel drove the Mercedes E class a whopping 1,223 miles over 27 hours to complete the challenge.
It's also worth pointing out, that when the car arrived at Goodwood, the on-board computer still said their was another 100 miles of diesel remaining in the tank - meaning there was plenty of fuel to complete a few runs of the famous hill at the Festival of Speed.
The journey also smashed the official fuel consumption figure of 68.9mpg - recording an incredible 73.6mpg!
