Over 17 days, 48 US states, and 13, 071km – roughly the distance taken to drive around Australia – the Volkswagen Passat TDI averaged just 3.02 litres per 100km.
The record beat the previous by 0.44 litres per 100km.
The official combined average fuel consumption for the US-spec Passat, which is different to the European-spec Australia receives, is 5.4 litres per 100km.
The only modification the test car received was a set of Continental low rolling resistance tyres, according to a Volkswagen spokesperson.
The drive tested the efficiency of Volkswagen’s production diesel engines when paired with the maker’s six-speed manual gearbox, but also “showed how much fuel consumption depends on the driver,” said blogger Wayne Gerdes, part of the driver team and a renowned ‘hyper-miler’ in the US.
This comes in light of the NRMA releasing a statement yesterday, warning local Australian motorists to expect a rise in fuel prices over the coming months.
Gerdes’ tip for motorists looking to maximise their fuel economy is to look ahead in traffic in order to plan gradual rather than sudden braking and acceleration, and to – you guessed it – drive slower.
