What is the Most Reliable Volvo Truck Engine and Why?


No matter what truck you get you should do some research on what engine does that truck come with and what transmission. For the sake of this post we will focus on Volvo trucks only. So what is the most reliable Volvo engine? Lets begin with listing the ones that come with purchasing a new Volvo truck.

Volvo D11

The first on our list is the D11 which can be configured in the new VNR the VNL VHD and VAH. With is low weight of only 2259lb, pushing 325Hp and 1250lb-ft of torque the D11 can make sure to haul your day to day loads with ease.

Volvo D13

The second in line is the Volvo D13 engine. The D13 is known mostly as the most versatile engine in its class. Coming in a variety of HP configurations: 375hp, 406hp, 425hp, 435hp, 455hp, 500hp.

Cummins ISX - X15

The next engine make have been around for a long time. The Cummins ISX15 available for the Volvo VNL models. The ISX15 have made quite an impression on Volvo truck owners. Boasting as reliable, durable, and long lasting the Cummins ISX15 is a great alternative to the Volvo engines with great results. Rating in 400-600 hp depending on the configuration the Cummins ISX is paved its way with impressive power and efficiency.

At 1850 lb-ft of torque and 485 hp (starting rating) the ISX15 has proven to be a powerhouse of an engine all while maintaining fuel efficiency for heavier hauls. Its no doubt the this engine has the capability of maintaining power and performance through every application a truck requires.

Which one is better?

Take into account what is required for the truck to haul. Compare how each engine rating stacks up in efficiency and performance. Having a lower HP or Torque rating for heavier loads will lower fuel efficiency as compared to having the right engine ratings. Ask what application will the truck be used for. Flatbed, van, reefer, heavy haul, specialized, or LTL all have various hauling weight.

Having the right engine rating haul will set you up for saving money in the long run and run into fewer issues.
