V6 3800 Engine:

Background:

On their website some years back, GM listed all the reasons they stuck with their cast iron, pushrod, wedge combustion chambered V engines. GM bought Hughes aircraft so they could use the electronics expertise. Their reasoning was that the Engine itself did not need to be changed, but the ancillary equipment did.

The reasons for persisting with their design were that their Engines were lighter, cheaper to make, cheaper
to repair and smaller than their alloy overhead cam counter parts.

Lighter:

The VN V6 was 5kgs lighter than the VL 3.0 Litre engine even though the latter had an alloy head.

Cheaper to Make:

Gearing up to build high tech engines placed huge financial strains on those companies that did.

Cheaper to Repair:

Being less sophisticated there was less time involved in a rebuild not to mention fewer parts.

Smaller:

With diminishing under bonnet space, the smaller the engine the easier it is to make the engine fit the car. Original thread.
