A pair of drivers from Toyota's UK based 'iQ blog' managed to break through 500 miles with a standard iQ 1.0-litre VVT-i (that's the petrol engine version) on a single tank of fuel. Mark and Simon from the 'iQ blog' traveled to 18 cities in two days on a route that took them as far west as Cardiff and as far north as Wolverhampton. In theory, since the official fuel economy of the iQ is rated at 65.7 UK mpg / 54.7 US mpg, the full 32-liter tank should have gone dry once they covered a distance of 462 miles.
However, and in spite of the fact that the two drivers said that they had to deal with wind, rain, congestion and the need to run the heater, headlights and wipers – factors that have a negative impact on fuel economy, the car managed 504.2 miles before the ending of its journey in central Oxford. Put the numbers together and that translates to an average of 71.6 UK mpg or 59.42 US mpg.
Even though the team's driving style was evidently focused on achieving a low fuel consumption, nevertheless, the end result is impressive since we're talking about real-life road conditions.
