April 4 is not a public holiday, unless you’re a real all-rounder.

Automakers and truck fans have claimed 4/4 as 4×4 Day to celebrate their favorite vehicles and hobbies.

In honor of the date, here’s a look at some of the most powerful serious 4×4 pickups and SUVs currently available in the United States from major brands.

Nissan Titan Pro-4X

The Nissan Titan lineup has one thing in common across all of its models, including the rugged Pro-4X: a 5.6-liter V8 that produces 400 horsepower and 413 lb-ft of torque.

Chevrolet Silverado ZR2

The Silverado ZR2 features a unique suspension system that makes it the most extreme version of the full-size pickup and is equipped with Chevy’s proven 6.2-liter V8, which develops 420 horsepower and 460 lb-ft of couple.

Toyota Tundra TRD Pro

The Toyota Tundra is all new for 2022 and the TRD Pro is the king of the model hill. It trades in the previous-generation Tundra’s V8 for a 3.5-liter twin-turbo V6 hybrid powertrain that combines the internal combustion engine and an electric motor to produce 437 horsepower and 583 lb-ft of torque.

Ford F-150 Raptor

The F-150 Raptor was the first high-speed off-road factory pickup, and the latest third-generation model is the fastest yet. Its 3.5-liter twin-turbo EcoBoost V6 is the most powerful in the F-150 lineup with 450 horsepower and 510 lb-ft of torque. However, it will soon be challenged by the F-150 Lightning electric pickup, which will soon be available with a 563 hp / 775 lb-ft powertrain, if not the Raptor’s hardcore equipment.

Jeep Wrangler Rubicon 392

It took Jeep nearly four decades to put a V8 engine in the Wrangler and was right when it finally did. The Wrangler Rubicon 392 is powered by a 392 cubic inch (6.4 liter) Hemi V8 rated at 470 horsepower and 470 lb-ft of torque.

Ram 1500 TRX

The F-150 Raptor was in a class of its own for a decade until the Ram 1500 TRX showed up with a supercharged V8 Hellcat borrowed from the muscle car Dodge Challenger with 702 horsepower and torque of 650 lb-ft.

Rivian R1T

Pedestal truck fans may argue that electric trucks have all-wheel drive and not 4×4 drives, but the Rivian R1T’s four-motor design makes a strong argument for the latter and puts an exclamation mark on it with 835hp and 908 lb-ft of torque.
