Answer / kumar

When the engine is place front of the vehicle,
1. When the vehicle move forward, since the air is hitting
directlr over the radiator and engine, the possibility of
engine cooling is high. Hence Powerloss due to over heating
will not arrise.
2. The possibility of fresh intake air without much dust
particles is high. If we place the engine at rear only air
with dust and pollutants will be sucked for intake hence
requires much more filteration and reduce the overall
efficiency.
