Automobile reports that the new 5.0L turbodiesel Cummins V8 destined for the next generation Nissan Titan was originally heading for use in the latest Ram 1500.
Though due to Ram’s alliance with Fiat via their parent company Chrysler, loyalties had Ram stuck sourcing their motor from VM Motori, a Fiat subsidiary, for the current 3.0L turbocharged EcoDiesel V6.
However, Chrysler claims that the reason Ram chose the 3.0L diesel V6 was due to fuel economy reasons. Chrysler wanted the diesel light-duty Ram to be capable of at least 26 mpg. Though the Cummins’ 5.0L turbodiesel V8 would return 23 to 24 mpg, according to Chrysler’s representatives and their research and simulation testing.
Heavy duty Rams will still be able to be equipped with Cummins’ latest 6.7L diesel inline-six.
