It is about a version with a high-output Cummins turbocharged diesel engine.
The 2021 Ram 3500 comes with the mentioned 6.7-liter 430-hp inline-six – only available on this model. The engine now delivers 1075 lb-ft of torque, it is 75 lb-ft more than before.
The truck with this engine can tow up to 37,100 pounds with a gooseneck hitch – 2000 lbs more than the previous 2020 model. The payload is 6,570 lbs.
The towing and torque figures surpass those of the 2021 Ford Super Duty, and make the 2021 Ram 3500 lead in the heavy-duty pickup truck class.
To add torque, Ram raised the boost limits with a variable-geometry turbocharger and increased the flow rate in the fuel-delivery system.
To increase the Ram 3500’s towing capacity, the manufacturer enhanced the truck’s heavy-duty frame and redesigned the fifth-wheel hitch.
Ram’s 6.7L Cummins Turbo Diesel I6 engine is mated to the fully electronically controlled Aisin 6-speed automatic transmission. The company upgraded the transmission to enhance durability, to quiet noise, vibration and harshness.
Sales begin this month. All 2021 trucks come with a digital rearview mirror. The base engine is a 6.4-liter 410-hp Hemi V8. It provides the payload capacity of up to 7,680 pounds.
