EcoDiesel, Part II: Fiat Chrysler's new light diesel aims to thwart GM and Ford, not the EPA



Domestic pickup couple wars again broke out. After a brief dormant period that followed Duramax's 3.0-liter 3.0-liter Duramax 3.0-liter inline-3 engine, which surpassed Ford's 3.0-liter V6 Power Stroke by 4 meters versus 460, Fiat Chrysler is arrival at the scene. to declare himself king of the hill.

For the 2020 model year, FCA's EcoDiesel 3.0-liter V6 diesel is back, this time without the luggage and after-the-fact modifications ordered by the federal government. He also pulls stronger than his competitors.

After a break in the model year, EcoDiesel will reappear in the Ram 1500 before 2020, generating this time 260 horsepower and 480 lb-ft of torque. The previous-generation engine, first introduced in 2014, produced 240 hp and 420 lb-ft.

Although Ford and GM failed to match line 1500, this old version left FCA a black eye. A scandal erupted in early 2017 over the automaker's use of unreported auxiliary monitoring devices, forcing the FCA to put itself on the defensive. The EPA opened an investigation, while the Justice Ministry filed a lawsuit against the manufacturer, forcing it to pay much less than the fine imposed on Volkswagen. Although the manufacturer never admitted that there was fault in the case, he cleaned the engine behavior.

This new plant has undergone significant changes. These include a new water-cooled turbocharger with a variable geometry turbine, redesigned cylinder head intake ports, an updated exhaust gas recirculation system and redesigned fuel injectors. The FCA claims that these and other modifications increase the engine compression ratio to 16.5: 1 (instead of 16: 1) and allow for "superb fuel economy and minimal noise levels, vibration and hardness.


"The new Ram 1500 EcoDiesel is the most powerful half-ton diesel pickup truck in the United States. It follows Ram Duty Heavy's leadership and offers what no other manufacturer has ever done: up to 480 lb-ft. of torque in a 3.0-liter engine, "said the boss of Ram Reid Bigland, who is currently suing his employer, in a statement.

The fuel economy ratings of the new EcoDiesel pickup have not been released yet, but Ram hopes his efforts will give another chance to boast. Buyers will be able to combine the new EcoDiesel with Ram's adjustable air suspension, which will further boost fuel economy.

As things stand, there are already two reasons: the torque mentioned above and the towing capacity of the engine of 12,560 pounds. The maximum towing capacity of the F-150 for diesel is 11,400 pounds; the Silverado 1500 is still unknown. Indeed, Ram can not yet claim the best tow in its class with certainty.

It is interesting to note that Ram plans to offer the new EcoDiesel not only in the second year of its new full-size vans, but also to the 2019 versions of the older generation 1500 Classic. All versions of the Ram 1500 can be equipped with a diesel engine, including the Rebel, according to the FCA.

Prices and fuel economy are close to the date of sale of the engine for the fourth quarter.
