One of the things that will have a bearing on fuel consumption is the weight of the car. By and large (and I am not forgetting Dave Mann's figures for his RN) it seems that the lighter the car, the better the fuel consumption reported.
For instance, a 1931 tourer weighs is at 'approx. 8 1/2 cwt' according to the handbook, whereas the RP saloon at 10 1/2 cwt
The other factor is that the LWB cars had a lower back axle ratio.
Yet another factor will be the state of tune of the engine. A well tuned engine in good condition will be more economical than one where this is not the case.
