Automotive WI - 1966 RWD GM V Platform eventually replaces other large RWD GM Platforms in US

As previously indicated in the engine section GM's various divisions already had 4-5 V8 engines potentially capable of being converted to diesel that could be used for commercial vehicles as well as passenger cars, from the Vauxhall V8, Oldsmobile V8 (both the 215 and regular V8), Buick V8 and even a hypothetical Opel CiH V8.

It is interesting to note that GM actually thought about winding down Opel in the post-WW2 aftermath (effectively leaving Vauxhall as the only GM division in Europe), due to being unsure about their ownership of what remained of Opel as well as whether they even wanted it back.

At the same time it would have been fascinating seeing either Opel (prior to pensioning it off to Holden / GM South Africa / America in favor of the Kadett A and CiH engines) or one of the US GM Marques, develop their own equivalents of the BMC B-Series and A-Series engines as they were in turn derived from the "D-Series" 4/6-cylinder engine that was itself a copy of the 2nd generation Chevrolet Straight-6 as well as formed the basis for a few Nissan engines.

- (A-Series) https://en.wikipedia.org/wiki/Nissan_E_engine
- (A-Series) https://en.wikipedia.org/wiki/Nissan_A_engine

Whichever GM division goes down such a route would potentially have a related range of 1000-2000cc 4-cylinder and 2000-3000cc 6-cylinder engines (aka GM "B-Series") as well as a downscaled 4-cylinder of 700-1600cc (aka GM "A-Series"), with both potentially capable of being dieselized, turbocharged and featuring OHC/DOHC (via OTL O/M/T-Series) and more.

Though it is unconfirmed have even heard rumours of a V8 engine being developed from a pair of Austin A40 engines by one Tadek Marek (prior to joining Aston Martin), the latter later forming the basis of the OTL B-Series. - https://en.wikipedia.org/wiki/BMC_B-Series_engine


Have been thinking of making similar threads on both Ford and Chrysler each exploring common platforms, though it seems the latter (via a few PODs) has more potential then the former with GM beating them both on the notion of using common platforms via VOH and TASC in OTL (plus the T-Car).
