All things being equal 460 series SWB with 5-speed which is the preferred engine in terms of performance, reliability and economy?
I guess that you referring to the OM602 (GD 250) and not, as Roly interpreted, to the OM616 (240 GD).
Both the OM602 and the OM616 are 5-in line naturally-aspirated diesels. Max power is 84 HP @ 4,600 and 88 HP @ 4,400 rpm respectively and torque is 157 Nm @ 2,200-2,800 and 172 Nm @ 2,400 rpm respectively, which should balance overall performance between the two.
The fact that the former is much more modern than the latter should mean better fuel consumption but this is apparently not the case.... the only published test of the 250 GD in SWB manual guise that I know of is that of the weekly Spanish magazine Autopista, which recorded a test consumption in it issue onf 22nd June 1989 of 15.2/100 Km, or 18.55 pmg (imp), well over the 12.7 (22 mpg) that I achieved over the ownership of my trusty 1984 300 GD SWB.
In any event, the 250 GD is a much rarer animal than the 300GD, with just 2,402 units made of all civilian versions as opposed to the 20,583 of the 300 GD.
