Toyota iQ hits more than 800 km on one tank of fuel in UK

Piloted by two of the team from the iQ blog, a standard iQ2 with a 1.0-litre VVT-i petrol engine, broke through 800 km on a single tank of fuel. What makes the achievement all the more remarkable is that this was no finely tuned marathon attempt, but a gruelling drive through some of the most congested town centres in the south and midlands of England and Wales.

Setting out from Brighton on 25th January, the team tagged 18 cities in two days on a route that took them as far west as Cardiff and as far north as Wolverhampton. With atrocious weather conditions and rush hour traffic to contend with, there was pessimism about reaching the target, given that the theoretical range from a full 32-litre tank in an iQ is 743.5 km. But in spite of wind, rain, congestion and the need to run the heater, headlights and wipers - all a drain on fuel consumption - the car managed 811.4 km before ending its journey in central Oxford. That works out at 30.44 km/l, compared to an official combined cycle figure of 27.93 km/l.
