Found following article in a magazine I bought while on holiday in Australia (Car News, Issue 14, 2001):
""Adventurer Hans Tholstrup has set a new Australian fuel consumption record of 43,5km per litre after driving a Honda Insight more than 1700kms from Brisbane(Qld) to Melbourne(Vic) on just 37,75 litres of fuel.
That is equivalent to acheiving 128,4 miles per gallon in the old currency.
The Insight is said to be the world's most fuel efficient petrol-powered production car averaged 46kms per litre during the trip.
Tholstrup drove with the windows up and no air-conditioning, with cabin temperatures of up to 50 degrees Celsius, in two shifts of five hours per day- the maximum allowed under regulations for the challenge.
"(At one stage) I figured I had enough fuel to do a little playing so I tried switching the air-conditioning on, but it dropped the fuel reading from 50km/litre to 45km/litre. I'd rather travel five kilometres further per litre than having air-conditioning." Mr Tholstrup said.
On one leg of the journey the car averaged 66 km/h with a top speed of 110 km/h.""
Quite interesting. Will take this magazine with everything else (Australian brochure, further Australian articles, press releases, workshop handbook on CD-Rom ....) I have about the Insight with me to the European Insight meeting for everyone to enjoy.
