Who knows if the final drive of the rear differential or the reduction of the sixth gear was changed during the production of the Gransport?
There are early 430 gramm CO2 cars and later 400 gramm CO2 cars.
Could this be explained by an extended final or sixth gear at the later cars or was there no change made in the gearbox/final drive ?
I know that the exhaust/cat converters layout was changed during the production, so maybe that was the reason for the differences in CO2 output?
