Motors could be about to revive its shuttered 4.5-litre V8 diesel engine according
to US sources.
Prompted by the upcoming launch of the latest Ram 1500 with a VM Motori 3-litre diesel and the Nissan Titan powered a brand new Cummins 5-litre ISX5 diesel
engine, both with compacted graphite iron (CGI) vee cylinder blocks, and the latest Ford 2015
F-150 pick-up truck with a new 2.7-litre EcoBoost gasoline engine (also with a CGI vee block), GM is considering adding a small-displacement diesel engine
to its Chevrolet Silverado and GMC Sierra 1500 pick-ups to boost fuel economy.
