Understanding Torque on Ram + Dodge Models
When people describe an engine’s power, they typically do it by explaining horsepower and torque. For instance, the SRT Hellcat engine produces 707 horsepower 650 lb-ft of torque. WOW! That’s a lot of torque. But what does torque even mean? Last week we explained horsepower, so this week we’re taking a look at torque.
Torque is a moment of force and it is the tendency of a force to rotate an object about an axis, fulcrum, or pivot. Just as a force is a push or a pull, torque can be thought of as a twist to an object. Torque is expressed as foot per pounds (ft-lb.)
In other words, torque gives the car or truck low-end power and the ability to move quickly after being stopped. In other words, torque lets a car do the work, but horsepower lets it do the work quickly.
Torque is very important to trucks because it directly affects towing capacity. The more torque, the more towing capacity. More torque is required to start a heavier vehicle than a lighter one. That’s why torque is useful when towing — torque is what allows a vehicle pull heavy loads.
Additionally, torque is the reason why diesel engines are popular option on trucks because they can produce more torque than comparable gas engines.
Torque in Numbers
To compare the torque between a diesel and gas engine, here’s a look at two Ram 2500 engines.
The Ram 2500 with a 6.7-liter I6 Cummins Turbo Diesel engine that generates 370 horsepower and 800 lb-ft of torque. This engine gives the Ram 2500 a Best-in-Class 17,980-pound maximum towing capability.
When equipped with the 6.4-liter V8 HEMI MDS engine the Ram 2500 produces 410 horsepower and 429 lb-ft of torque, which is quite a difference. The Ram 2500 6.4-liter V8 HEMI MDS engine has a towing capacity of 16,320 pounds.
Dodge and horsepower are definitely not the only traits that are important when car shopping, but they are indicators about the power you can expect a new car to have. Not all Dodge and Ram models have the extreme torque like the SRT Hellcat or 6.7-liter Cummins Turbo Diesel, and not everyone needs that much torque, but for those that love a lot of power, Dodge and Ram are one of the best brands.
