Last week RAC enlisted the help of two drivers - Andrew Frankel and myself - to help conquer a Guinness World Record, writes Rebecca Jackson.
The idea was to drive through as many countries as possible on one tank of fuel without travelling on a ferry or train; Record Road Trip was the code name given for the event. The tank was a 73 litre diesel in an Audi A6 2.0 Ultra fitted with a DSG automatic gearbox. We started in the Netherlands and a carefully planned route meant we avoided traffic jams as much as possible thus keeping the car moving for almost 28 hours of nonstop driving. Breaks were limited to less than 20 minutes as this is when the car would start to lose its efficiency due to heat loss. Andrew and I swapped seats every 4 hours at these short stops and managed to cover 1158 miles, drive through 14 countries and average an economy figure of 75.9MPG. Two key features of the car, other than it being fairly frugal anyway, that aided our success are Audi’s coasting function as a safe way of allowing the car to run in neutral down hill, and the ability to manually select a gear with the paddle shifts positioned behind the steering wheel. Despite this, it will not allow the revs to drop too low before automatically selecting the lower gear. Therefore it was vital to travel at the right speed for each gear. We found that around 1100 RPM and approximately 57MPH seemed to work for 7th gear on the flat. Our average speed throughout was 46MPH. An adjudicator from Guinness World Record joined us on our challenge supervising the sealing of the fuel tank, ensuring no modifications had been made to the car and congratulated us at the end with a formal presentation of a framed certificate.
