Toyota UK said, “The Prius PHV established a fuel-efficiency of 698miles/gallon in real-world testing”.
Toyota Prius has set the record for being the most fuel economic car to date. The car went around the north course of Nurburgring, Germany, covering 20.8 km in a time of 20 mins 59 sec at an average speed of 60 km/h, in a driving test arranged by Toyota’s British Corporation.
The Prius PHV set an amazing record of 247 km/litre for fuel efficiency, it happened because the Nurburgring Nordschleife circuit has a section which can be used to drive at EV mode only. As a result, the fuel efficiency of Toyota Prius is listed as 47 km/litre in the UK catalogue of Toyota.
