The Spec C had a 50L tank. Filled to the brim, i would get 600km out of a tank with highway (open road) driving. Thats a mild 100-120kph (maybe the odd burst to 160ish on desert road), overtaking anything slower than 100kph, rapidly.
BP98 only.
This was achieved about 6 or 7 times in regular trips from Auckland to Palmy-Levin and back...
By comparisson, my Safari weighs 1100kg more, is 4.2L diesel auto and will do 600km's on a tank (95L) highway. Thank god diesel is around 70c a litre cheaper than 98!
