GM would be wise to line up the Cummins 2.8L ISF diesel engine for light duty 1/2 ton trucks.
160hp and 266 ft-lb torque. It would provide super fuel mileage with a 5 speed transmission.
The EPA ratings would have to be worked out but it carries a Euro 4 emmissions rating already.
Dodge had a great run with the Cummins "B" series 5.9L engines.
This is the super engine that could bring GM light trucks to the lead in sales.
