What is the fastest truck engine?

While “fastest” can be interpreted in different ways, considering outright acceleration, the title goes to the Ford F-150 Raptor R.

Here’s a breakdown of its impressive performance:

  • Engine: Supercharged 5.2-liter V8 engine borrowed from the discontinued Shelby GT500
  • Horsepower: 700 hp
  • Torque: 640 lb-ft
  • 0-60 mph acceleration: Under 4 seconds

This combination allows the Raptor R to outperform other contenders known for their speed, like the:

  • Ram 1500 TRX: While still very powerful with its 702-hp supercharged 6.2-liter V8, it falls slightly behind the Raptor R in 0-60 mph acceleration, taking around 4.5 seconds.
  • Hennessey Ram 1500 TRX Mammoth: This heavily modified version of the TRX boasts 1,012 hp, but its official 0-60 mph time hasn’t been widely reported.

It’s important to remember that “fastest” can also refer to other aspects like top speed. However, due to factors like safety regulations and tire limitations, most trucks, including the ones mentioned above, have electronically limited top speeds around 110-120 mph.

Therefore, while the Ford F-150 Raptor R currently holds the crown for the fastest acceleration in a production truck, it’s crucial to consider the specific context and definition of “fastest” when comparing truck engines.
