Correct.IIRC you put a 1275cc engine in it though.
The last time I worked it out, my fairly standard 1098cc Traveller was doing about 35mpg on the daily commute going up to 40+ on long runs.
But, my 1098 was never that good either. I dont know whether this was because the 1098 had to be driven harder to get the same results or whether it was just way out of tune (though it drove perfectly).
To be honest I was happy with 35mpg. It 'could' do better but at a significantly reduced fun level.
If you want economy - buy a diesel or cycle to work. Driving 10-15 miles a day in stop-start traffic is going to drain even the most frugal of vehicles.
