Citroën – Arsenal ‘premier’ car wash

Boffins at Citroën, together with an applied mathematician, devised that E = 1/t + 1W, E is efficiency, t is the time taken for the car wash and W is the amount of water used.

Premier League team, Arsenal and first team players Thomas Vermaelen, Per Mertesacker, Aaron Ramsey and Olivier Giroud created the most ‘premier’ car wash of the season to test the calculation at the Club’s training ground.
