Peterbilt vs Kenworth: Which is Better?

Most CDL owners are fixed on their favorite semi truck, be it Freightliner, Peterbilt, Kenworth, Volvo, or the various other brands.

But when it comes down to Peterbilt vs Kenworth, which is the better truck?

Both models offer a lot of power, awesome driver mechanics, unique features, and a smooth ride. Choosing one over the other depends on what you're able to afford upfront, your driving habits, and your personal style preferences.

Here's a detailed comparison between the two.

Kenworth vs Peterbilt Trucks: Pros and Cons

Between the two truck models, it’s a close call. There is no “better truck,” since both are fuel efficient and have a lot of torque. 

However, Peterbilt tends to have more horsepower than Kenworth. Both of them offer a sleek, aerodynamic design meant to save an estimated 7% on fuel use.

Peterbilt is known for some iconic, stunning designs, like the classic Peterbilt 379 and the customizable Peterbilt 359, featuring a spacious cab with plenty of leg room for drivers. However, the long nose design of these models can present challenges with sightlines and handling in tight spaces.

Kenworth trucks are known for their technological efficiency and reliability, featuring flagship models like the T680 and the classic W900. Kenworth sleeper cabs are smaller than Peterbilt cabs for enhanced maneuverability. Additionally, the sloped hood design in some Kenworth models improves visibility and handling, especially in tighter spaces.

The price of aftermarket replacement truck parts and repair service costs are pretty much the same between the two.
