The Lexus NX remains a compelling option in the luxury compact SUV segment, with the latest lineup offering distinct choices for discerning drivers. Two key variants, the NX 250 and NX 350, offer distinct approaches to performance, efficiency, and feature content, while maintaining the refined character that defines the Lexus brand. Understanding the differences between these two models is essential for potential buyers seeking the right balance of power, luxury, and technology.
2025 Lexus NX 250 Vs NX 350
Powertrain Differences
The most significant distinction between these two models lies under the hood. The NX 250 features a naturally aspirated 2.5-litre four-cylinder engine producing 203 horsepower and 250 Nm of torque. This powertrain is paired with an eight-speed automatic transmission and is available in both front-wheel and all-wheel drive configurations.
In contrast, the NX 350 employs a more powerful 2.4-litre turbocharged four-cylinder engine generating 275 horsepower and 430 Nm of torque—representing a substantial 35% increase in horsepower and 72% increase in torque over the 250. The 350 comes standard with all-wheel drive and the same eight-speed automatic transmission, though with specific tuning to handle the additional power.
These powertrain differences translate directly to on-road performance. The NX 250 accelerates from 0 to 100 km/h in approximately 8.8 seconds, while the turbocharged NX 350 accomplishes the same sprint in a more brisk 6.6 seconds.
Fuel Efficiency
Despite its significant power advantage, the NX 350 turbocharged engine remains relatively efficient. It delivers approximately 10.7 L/100 km in combined driving conditions. The NX 250 is the more fuel-efficient option, however, with a combined rating of approximately 8.8 L/100 km for the front-wheel drive model and 9.0 L/100 km for the all-wheel drive variant.
Both models feature an Eco driving mode that adjusts throttle response and climate control settings to maximize efficiency, though the effect is more pronounced in the naturally aspirated NX 250.
Exterior and Dimensional Differences
Visually, these two models share the same fundamental design language, including the distinctive spindle grille and sharp character lines. However, the NX 350 features subtle differentiation through model-specific elements:
- Larger 20-inch alloy wheels (compared to 18-inch on the NX 250)
- Unique front bumper design with larger air intakes
- Dual exhaust outlets (versus single outlet on the NX 250)
- Model-specific badging
Dimensionally, both models are identical, with a length of 4,662 mm, width of 1,865 mm, and height of 1,669 mm. The wheelbase measures 2,690 mm, and ground clearance is 190 mm for both variants.
Interior and Technology Features
The interior architecture is consistent between both models, featuring the Lexus Interface system centered around a standard 9.8-inch touchscreen (with an available 14-inch upgrade). However, the 350 includes several additional standard features that are optional on the 250:
- Heated and ventilated front seats
- Leather upholstery (versus NuLuxe synthetic leather in the NX 250)
- Ambient interior lighting with 64 colour choices
- Power tailgate with kick sensor
- Enhanced driver memory system
Both models come standard with wireless Apple CarPlay and Android Auto integration, a 10-speaker audio system (with an available 17-speaker Mark Levinson premium audio upgrade), and a wireless charging pad.
Safety and Driver Assistance
The Lexus Safety System+ 3.0 is standard on both the models, providing a comprehensive suite of driver assistance technologies, including:
- Pre-Collision System with Pedestrian Detection
- Lane Tracing Assist and Lane Departure Alert
- Dynamic Radar Cruise Control
- Road Sign Assist
- Proactive Driving Assist
The NX 350 adds standard blind spot monitoring with rear cross-traffic alert and front and rear parking sensors—features that are optional on the NX 250.
Driving Dynamics
Beyond raw performance metrics, these two models offer distinct driving experiences. The NX 250 prioritizes refined comfort, offering linear power delivery and a quieter cabin, thanks to its naturally aspirated engine. The NX 350 turbocharged powertrain provides more immediate response and passing power, particularly noticeable in highway driving scenarios.
Both models utilize the Lexus GA-K platform, which provides a rigid foundation that balances ride comfort with handling precision. However, the 350 features standard Adaptive Variable Suspension that continuously adjusts damping force based on road conditions and driving style—a feature not available on the 250.
The NX 350 also benefits from a more sophisticated all-wheel drive system with Dynamic Torque Control, which can direct up to 50 percent of engine power to the rear wheels when needed, thereby enhancing both traction and handling characteristics.

5 Facts About the 2025 Lexus NX 250 and 350
- The 350 turbocharged engine produces its maximum torque at just 1,700 RPM, compared to the 250 peak torque at 4,400 RPM, resulting in significantly different throttle response characteristics.
- Engineers spent over 1,000 hours fine-tuning the acoustics of both NX models to minimize unwanted noise while amplifying engineered sound feedback during acceleration.
- The Door Digital Latch system on both models was inspired by the movement of a Japanese sliding door, replacing traditional door handles with an electronic release system that prevents door opening if an obstacle (like a cyclist) is detected approaching.
- The available panoramic moonroof utilizes electrochromic glass technology, which can switch from transparent to opaque at the touch of a button, eliminating the need for a conventional sunshade.
- The NX 350 turbocharger features a “twin-scroll” design, which separates exhaust pulses from alternating cylinders, thereby reducing turbo lag and enhancing throttle response compared to conventional single-scroll turbos.
