The team calculates the Carpuccino will do three miles per kilo of ground coffee - the equivalent of about 56 espressos per mile.
The journey will use about 70 kilos of ground coffee which, at supermarket prices of between £13 and £26 a kilo depending on brand and quality, will cost between £910 and £1,820, or between 25 and 50 times the £36 cost of petrol for the journey.
