The Nissan Frontier PRO-4X 3.8 V6 4×4 Automatic, representing the facelifted third generation of the Frontier, debuted in August 2024. This variant occupies the premium end of the Frontier lineup, positioned as Nissan’s most off-road capable offering. Building upon the redesigned D23 generation launched in 2022, the 2024 refresh brought updated styling and enhanced technology. The PRO-4X trim is specifically geared towards enthusiasts seeking a blend of capability, comfort, and modern features in a mid-size pickup truck. It serves as a direct competitor to trucks like the Toyota Tacoma TRD Off-Road and the Chevrolet Colorado ZR2.

Powertrain & Engine Architecture
The heart of the Frontier PRO-4X is Nissan’s 3.8-liter VQ38DD V6 engine. This naturally aspirated engine produces 310 horsepower at 6400 rpm and 381 lb-ft of torque at 4400 rpm. The VQ engine family is a long-standing staple of Nissan’s lineup, known for its reliability and smooth power delivery. The VQ38DD utilizes direct fuel injection and a dual overhead camshaft (DOHC) valvetrain with Continuously Variable Valve Timing Control System (CVVTCS) for optimized performance and efficiency. The engine is longitudinally mounted, driving all four wheels through a sophisticated 9-speed automatic transmission. This transmission, a relatively recent addition to the Frontier, offers improved shift quality and a wider gear ratio spread compared to the previous 7-speed unit, enhancing both acceleration and fuel economy.
Driving Characteristics
The 9-speed automatic transmission in the PRO-4X is tuned for a balance of responsiveness and efficiency. While not as aggressively geared for outright acceleration as some competitors, it provides smooth and predictable shifts. The wider gear ratios allow the engine to operate within its optimal power band more frequently, contributing to usable torque in various driving situations. Compared to a manual transmission equipped Frontier, the automatic prioritizes ease of use and comfort, making it well-suited for daily driving and towing. The PRO-4X’s off-road focused suspension and all-wheel drive system, combined with the V6’s torque, provide excellent traction and control on challenging terrain.
Equipment & Trim Levels
The PRO-4X trim comes standard with a comprehensive suite of features. Interior appointments include unique two-tone upholstery, heated front seats, and a leather-wrapped steering wheel. Standard technology includes a 9-inch touchscreen infotainment system with Apple CarPlay and Android Auto compatibility, a premium audio system, and Nissan Safety Shield 360, a suite of advanced driver-assistance systems. Optional extras include a sunroof, spray-in bedliner, and upgraded off-road accessories like a winch and skid plates.
Chassis & Braking
The Frontier PRO-4X features a robust chassis designed for both on-road comfort and off-road durability. The suspension consists of a double wishbone setup at the front and a rigid axle with leaf springs at the rear. Bilstein shock absorbers are standard, providing enhanced damping and control. Braking duties are handled by ventilated discs at all four corners, providing ample stopping power. The PRO-4X also benefits from an electronically controlled locking rear differential, enhancing traction in low-grip situations.
Market Reception & Comparison
The 2024 Nissan Frontier PRO-4X has been generally well-received by automotive critics. Praise has been directed towards its capable off-road performance, comfortable ride quality, and user-friendly technology. Fuel economy, however, is a common criticism, with the combined EPA rating of 18 mpg falling slightly behind some competitors. Compared to the base Frontier models, the PRO-4X offers a significant upgrade in terms of features, capability, and overall refinement. Reliability is expected to be good, given the VQ engine’s proven track record.
Legacy
The VQ38DD engine, while not the most fuel-efficient in its class, has established a reputation for long-term durability and relatively low maintenance costs. The 9-speed automatic transmission, while newer, has proven to be a reliable unit in other Nissan applications. The 2024 Frontier PRO-4X represents a compelling option for buyers seeking a capable and well-equipped mid-size pickup truck, and its robust construction suggests it will hold its value well in the used car market.
