Duke students break Guinness World Record for fuel efficiency


Duke Engineering is now the official home of the most fuel-efficient vehicle in history – a hydrogen (H2) fuel cell car that gets the equivalent of 14,573 miles per gallon.

Duke Electric Vehicles (DEV’s) record-breaking run took place on Saturday 21st July at Galot Motorsports in Benson, North Carolina. Guinness World Records has confirmed that the attempt to set a new record for fuel efficiency was successful. DEV bested the old record set by ETH Zurich, which stood for 13 years.

Engineers from NC State University and North Carolina A&T State University judged the attempt, measuring total H2 consumption, total distance travelled, and total time of the run, ensuring the car travelled at a minimum average speed of 15 mph. The efficiency score was computed based on total distance travelled divided by total H2 consumption.
