The Lexus NX 250 AWD, introduced for the 2021 model year as part of the NX II (AZ20) generation, represents Lexus’s entry point into the compact luxury crossover segment in North America. Positioned below the NX 350 and the NX 450h+ plug-in hybrid, the NX 250 offers a more accessible price point while still delivering the brand’s signature refinement and features. It serves as a key model in Lexus’s strategy to broaden its appeal and compete effectively against rivals like the Acura RDX, BMW X3, and Audi Q5. The AZ20 generation marked a significant redesign for the NX, incorporating updated styling, technology, and a new platform.

Powertrain & Engine Architecture
The Lexus NX 250 is powered by the A25A-FKS 2.5-liter inline-four cylinder engine. This engine utilizes a combination of direct injection and multi-port fuel injection, a system known as D-4S, to optimize combustion efficiency and power delivery. The engine features a dual overhead camshaft (DOHC) valvetrain with variable valve timing with intelligence (VVT-i) on both intake and exhaust camshafts. This technology allows the engine to adjust valve timing based on driving conditions, improving both performance and fuel economy. The engine produces 203 horsepower and 183 lb-ft of torque. The engine is paired with an 8-speed automatic transmission (ECT-i – Electronically Controlled Transmission with intelligence). This transmission is designed for smooth and responsive shifting, and features adaptive shift logic that learns the driver’s habits. The AWD system is primarily front-wheel drive, with the rear axle engaging as needed to provide additional traction.
Driving Characteristics
The NX 250’s driving experience is characterized by its smooth and comfortable ride. The 8-speed automatic transmission provides adequate performance for everyday driving, but it isn’t particularly sporty. Acceleration from 0-60 mph takes approximately 8.6 seconds. Compared to the more powerful NX 350, the NX 250 feels noticeably less energetic, especially during highway merging and overtaking maneuvers. The transmission’s gear ratios are tuned for fuel efficiency rather than outright performance. The AWD system provides enhanced stability and traction in inclement weather, but it doesn’t transform the NX 250 into a performance-oriented vehicle. The steering is light and precise, making it easy to maneuver in urban environments.
Equipment & Trim Levels
The NX 250 typically comes standard with a generous array of features, including Lexus Safety System+ 3.0 (which includes Pre-Collision System with Pedestrian Detection, Lane Departure Alert with Intelligent Steering Assist, and Dynamic Radar Cruise Control), an 9.8-inch touchscreen infotainment system, Apple CarPlay and Android Auto compatibility, and a suite of driver-assistance technologies. Interior upholstery is typically NuLuxe simulated leather, with available upgrades to genuine leather. Optional extras include a Mark Levinson premium sound system, a panoramic sunroof, heated and ventilated front seats, and a power rear door. Trim levels generally include base, Premium, and Luxury, with each successive trim adding more features and refinement.
Chassis & Braking
The NX 250 utilizes a MacPherson strut front suspension and a double wishbone rear suspension. This setup provides a comfortable ride and good handling characteristics. The chassis is designed to minimize noise, vibration, and harshness (NVH), contributing to the Lexus’s reputation for refinement. The NX 250 is equipped with ventilated disc brakes on all four wheels. Anti-lock braking system (ABS), electronic brake-force distribution (EBD), and brake assist are standard features. The suspension is tuned for comfort, prioritizing ride quality over sporty handling. Stabilizer bars are present on both axles to reduce body roll during cornering.
Market Reception & Comparison
The NX 250 has been generally well-received by automotive critics as a solid entry-level luxury crossover. Reviewers have praised its comfortable ride, spacious interior, and standard safety features. However, some have criticized its relatively modest performance compared to its competitors. Fuel economy is competitive within its class, achieving around 28 mpg combined. Compared to the NX 350, the NX 250 offers a lower price point but sacrifices some performance and refinement. The NX 250’s reliability is expected to be excellent, consistent with Lexus’s strong reputation for dependability.
Legacy
The A25A-FKS engine and the 8-speed automatic transmission used in the NX 250 are relatively new designs, and long-term reliability data is still emerging. However, Lexus has a strong track record of building durable and reliable vehicles, and the NX 250 is expected to follow suit. On the used car market, the 2021 and later NX 250 models are likely to hold their value well due to the Lexus brand’s reputation and the vehicle’s appealing combination of features, comfort, and fuel efficiency. The NX 250 represents a key step in Lexus’s transition towards a more diverse and technologically advanced lineup.
