The figures – double the official fuel consumption of the 308 – were recorded by the winning driver over 622 miles between Paris and Geneva last week.
Overall 72 drivers took part in the ‘race’, coming from 18 different countries worldwide to drive one of four Peugeot diesel models; the Peugeot 308, Peugeot 207, Peugeot 5008 and Peugeot 3008.
Each country represented entered four teams consisting of two people, with the goal of beating a benchmark mpg figure set by 2009 Le Mans 24-hour winning driver Stephane Sarrazin.
The Slovakian driver Tomas Sarik recorded the best fuel economy in the Peugeot 308 hatch, with drivers from Belgium, Croatia and Czech Republic recording winning results in the other models.
Although the highest figures were recorded by the five-door hatchback, the seven-seat Peugeot 5008 MPV achieved 84.77mpg and the Peugeot 207 delivered 87.10mpg.
Jon Goodman, Managing Director of Peugeot UK, said: "This is a great reminder that, in this dynamic and technology-obsessed industry, genuine environmentally friendly motoring is available for the masses right now."
