The Nissan Frontier I Regular Cab (D22), particularly the facelifted version produced from 2000 to 2004, represented Nissan’s entry into the North American compact pickup truck market. Positioned as a more affordable and maneuverable alternative to full-size trucks like the Ford F-150 and Chevrolet Silverado, the D22 aimed to capture buyers needing a utilitarian vehicle for work or recreational purposes. The 2.4-liter (143 hp) variant, while not the most powerful offering in the Frontier lineup, served as the base model, prioritizing fuel efficiency and lower initial cost. It was a key component of Nissan’s strategy to gain market share in a segment dominated by domestic manufacturers.

Powertrain & Engine Architecture
The heart of the 2000-2004 Nissan Frontier 2.4 was the KA24DE engine, a 2.4-liter inline-four cylinder powerplant. This engine, a staple in Nissan’s lineup for many years, featured a cast iron block and an aluminum cylinder head. It utilized a multi-port fuel injection system, delivering fuel directly into each intake port for improved combustion efficiency. The KA24DE boasted a double overhead camshaft (DOHC) valvetrain with four valves per cylinder, contributing to its respectable power output for its displacement. The engine was known for its relative simplicity and durability, though it wasn’t particularly sophisticated by contemporary standards. The 5-speed manual transmission was the standard pairing for this engine, offering a direct connection between the engine and the rear wheels. The transmission’s gear ratios were tuned for a balance of acceleration and fuel economy, prioritizing usability over outright performance.
Driving Characteristics
The 143 horsepower and 154 lb-ft of torque produced by the KA24DE in the Frontier 2.4 resulted in adequate, but not exhilarating, performance. Acceleration was modest, particularly when the bed was loaded or towing a trailer. The 5-speed manual transmission allowed drivers to keep the engine in its optimal power band, but the engine lacked the low-end grunt of larger displacement engines. Compared to the optional 3.3-liter V6, the 2.4-liter engine felt noticeably less powerful, especially during highway merging and passing maneuvers. However, the 2.4-liter engine offered better fuel economy and a lighter front end, contributing to improved handling and maneuverability in urban environments. The rear-wheel-drive configuration provided a traditional truck feel, with a focus on utility and load-carrying capability.
Equipment & Trim Levels
The base Frontier 2.4 Regular Cab was typically sparsely equipped, reflecting its position as the entry-level model. Standard features generally included a basic AM/FM radio, vinyl upholstery, and manual windows and locks. Air conditioning was often an optional extra. Higher trim levels, such as the XE and SE, added features like power windows and locks, upgraded audio systems, and alloy wheels. Interior materials were generally durable and utilitarian, prioritizing functionality over luxury. The dashboard layout was straightforward and easy to use, with clearly labeled controls. Optional extras included a sliding rear window, cruise control, and a towing package.
Chassis & Braking
The Frontier I Regular Cab utilized a body-on-frame construction, providing a robust and durable platform for hauling and towing. The front suspension consisted of double wishbones, while the rear suspension employed leaf springs. This configuration provided a comfortable ride quality, particularly when unladen, but could become somewhat harsh when carrying heavy loads. The braking system featured ventilated discs at the front and drum brakes at the rear. While adequate for normal driving conditions, the braking performance wasn’t particularly strong, especially when compared to more modern vehicles. The steering was hydraulic power-assisted, providing a reasonable level of feedback and control.
Market Reception & Comparison
The Nissan Frontier 2.4 was generally well-received as a practical and affordable compact pickup truck. Critics praised its maneuverability, fuel efficiency, and durability. However, the engine’s lack of power was a common criticism, particularly when compared to the V6 options offered by Nissan and its competitors. In terms of fuel economy, the 2.4-liter engine typically achieved around 20-25 mpg in combined driving, making it a more economical choice than the V6. Reliability was generally good, with the KA24DE engine proving to be a durable and long-lasting powerplant. Compared to the Ford Ranger and Chevrolet S-10, the Frontier offered a more modern design and a more comfortable interior.
Legacy
The Nissan Frontier I Regular Cab 2.4, while not the most powerful or feature-rich pickup truck on the market, established Nissan as a credible competitor in the compact truck segment. The KA24DE engine, despite its age, remains a relatively reliable and affordable engine to maintain. Today, these trucks can be found in the used car market at very affordable prices, making them attractive options for buyers seeking a simple, utilitarian vehicle. However, potential buyers should be aware of the engine’s age and potential for wear and tear. Parts availability is generally good, but some components may be becoming increasingly difficult to find. The Frontier 2.4 remains a testament to Nissan’s commitment to building durable and practical vehicles.
