iMobility Challenge ecodriving competition results


From 16 to 19 June iMobility Challenge organised an Ecodriving Competition at the European ITS Congress in Helsinki. Every congress delegate could take a short drive in Helsinki and see how their energy-efficient driving skills compare to a benchmark score set by Finnish F1 star, Valtteri Bottas.

Valtteri Bottas said: “The road is not the race track, so when I drive in the city I aim to drive in a safe and efficient manner. It is great that modern technologies help drivers understand how their driving style affects their energy consumption, and make responsible driving fun.”

An ENERFY on-board device and smartphone APP monitored the energy efficiency of the drivers’ performance (

Here is the outcome of the competition:

  •        Total participants: 262
  •        Total number of drives: 445 (many participants tried more than once), Ecodriving is Fun!
  •        Valtteri’s Enerfy score was 1229 points : position 121
  •        Valtteri drove 36% more fuel efficient than the world average.
  •        46% of the participants manage to achieve Vallteri’s excellent score, some tried several times to managed it. Anyone can be a fuel-efficient driver if he/she wants to!  
  •        The participants drove 2 kms in Helsinki’s traffic.
  •        The top performers averaged 1338 points compared to 596 for the lower end of the board. Translated into in fuel efficiency, the difference was equivalent to 37,2 percent: that’s how much difference your driving style has on energy consumption!
  •    The top of the leader board didn’t just use less energy to get the car around the track, they also were around 4% quicker: Ecodriving does not mean slow driving!

The overall winners of the total event from 16-19 June 2014:
