Volkswagen announced that it has entered the Guinness World Record Book after journalist Gavin Conway writing for Sunday Times, has driven the VW Passat BlueMotion a distance of 1531 miles on just one fuel tank.  
The 1531 miles record set by the VW Passat BlueMotion means the same as driving from London to Malaga or from Los Angeles to New York without refuelling.
The VW Passat BlueMotion used in this challenge was a regular production version powered by a 1.6-litre TDI engine developing 105 PS which features Stop Start technology, programmed battery charging, a longer gear transmission, low resistance tyres and a lowered ride height.
The amount of fuel used by the VW Passat BlueMotion to cover 1531 miles was 77.25 litres which means a combined fuel consumption figure of 64.2 mpg.
Volkswagen press release :
A Volkswagen Passat BlueMotion driven by journalist Gavin Conway writing for The Sunday Times has set a new Guinness World Record for the distance travelled by a production passenger car on a single tank of fuel.
In setting the record the Passat BlueMotion travelled a distance of 1,531-miles, the equivalent of driving from London to Malaga, without needing to refuel or travelling from Los Angeles to New York with a single stop for fuel.
Powered by a Volkswagen 1.6-litre common rail TDI engine developing 105 PS, the Passat BlueMotion used for the record attempt was a standard production model. In common with the Polo and Golf BlueMotion models, the Passat is fitted with aerodynamic modifications to the bodywork, a lower ride height, Stop-Start, programmed battery charging, longer gearing and low rolling resistance tyres. The result is a vehicle that is completely conventional to drive, service and maintain yet among the most efficient vehicles on the road today.
The record breaking feat was monitored throughout by independent representatives on behalf of the Guinness World Records organisation. The amount of fuel used was accurately measured at 77.25 litres resulting in an overall fuel consumption of 90.0 miles per gallon, substantially exceeding the claimed combined figure of 64.2 mpg.
