Whilst discussing (read bickering) with my friend via email he was on about how my old Visa diesel was a 1.7
Now it was the 1769cc engine as fitted to the bx etc but why on the visa and bx was it badged as 17RD. Using the standard method of rounding off numbers, 1.750 or higher rounds up to 1.8 so therefore 1.769 rounds up to 1.8, why did citroen go the other way?

Maybe because the smaller engine was XUD7??
