I've had a look but I can't find it, I saw it a few months ago. Hopefully someone else will be able to provide the quote.
Not trying to be mean but what will change the diesel engine other than a bit more torque ? (I don't think it's useless, i just don't see the difference between diesel and gasoline)
Sorry for the delay response I got busy with other game stuff. Now I may be entirely wrong, but I believe the diesel engines were just showing off and if I remember one of the devs put it into the Grand Marshall so it may go into the d-series but there is just so little info I won't hold much value unless a dev says which vehicles won't get it.
Only the H-Series and D-Series (and in turn, the Roamer) have the mesh for the diesel. There is no current mesh in any in-game file that contains a diesel engine for the Grand Marshal.
That thread was also originally for the purpose of showing off the new 3D mesh for the engine - if you look closely, you'll notice the engine in the Grand Marshal has several different components from the diesel - the intake assembly is the most noticeable.
There was never an image showing the GM with the diesel engine. What I was trying to do was highlight the visual differences between the engine in this picture: And the diesel engine in this picture: As long as I've got them both out, I may as well point out the differences I could spot - note the presence of a turbocharger (and all involved plumbing) on top of the engine, the different colour of intake manifold, and the fuel injection lines arching over the valve covers. At this time, we have not received any indications that the diesel will be finding its way into the Grand Marshal - but it's worth noting that diesel engines often find their way into Crown Victorias in the course of a custom project. Given that the Gavril engines appear to be based off of the same basic architecture, they should theoretically bolt right into the Grand Marshal - making these projects much easier and more common in the Beamverse. Then there's the longstanding murmur around Gavril engines in the 200BX. Chucking a large turbodiesel in there would probably produce some interesting results...
That's perhaps a possibility, another one might be to rearrange the rear suspension. The GNX used special torque bars to lift the body and press down on the rear tires; I'm wondering if it's theoretically possible for the rear suspension to help lift the body in such a way that it presses down on the front tires.
The GNX rear suspension was pretty standard 4-link live axle stuff, It just had a very aggressive geometry that gave a lot more anti-squat, at the cost of suspension travel. It wouldn't really do anything on a FWD car, there's no good way to press the front wheels into the ground other than aero.
Looks like I should have done more research. What would very aggressive anti-lift geometry do to a FWD car?
