Whats the difference between Lexus NX 300h and 350h?


The Lexus NX series has gained popularity for its blend of luxury, performance, and efficiency. Among its offerings, the NX 300h and NX 350h stand out as hybrid options that cater to different preferences and needs. In this article, we will explore the key differences between these two models, helping you make an informed decision if you're considering a purchase.


Powertrain and Performance


One of the most significant differences between the Lexus NX 300h and NX 350h lies in their powertrains. The NX 300h is equipped with a 2.5-liter four-cylinder engine paired with an electric motor, producing a combined output of around 194 horsepower. This setup is designed for efficiency, offering a smooth and quiet ride while achieving impressive fuel economy.


In contrast, the NX 350h features a more powerful hybrid system that combines a 2.5-liter four-cylinder engine with a more robust electric motor, resulting in a total output of approximately 240 horsepower. This increase in power translates to a more dynamic driving experience, making the NX 350h a better choice for those who prioritize performance alongside efficiency.


Fuel Efficiency


Both models are designed with fuel efficiency in mind, but they do differ slightly in their ratings. The NX 300h typically achieves around 33 mpg in the city and 30 mpg on the highway, making it an excellent option for those who do a lot of urban driving.


The NX 350h, while still efficient, offers slightly lower fuel economy due to its increased power. It generally provides around 39 mpg in the city and 36 mpg on the highway, which is impressive for a vehicle with its performance capabilities.


Interior and Technology Features


When it comes to interior quality and technology, both the NX 300h and NX 350h offer a luxurious experience. However, the NX 350h tends to come with more advanced features as standard. Here are some highlights:



  • Infotainment System: The NX 350h often includes a larger touchscreen display with enhanced connectivity options, including wireless Apple CarPlay and Android Auto.

  • Safety Features: Both models are equipped with Lexus Safety System+; however, the NX 350h may offer additional driver-assistance features as standard.

  • Interior Materials: The NX 350h may feature upgraded materials and finishes, providing a more premium feel compared to the NX 300h.


Price and Value


Pricing is another critical factor to consider. The NX 300h generally has a lower starting price, making it an attractive option for budget-conscious buyers who still want a luxury hybrid SUV. The NX 350h, with its enhanced performance and features, comes at a higher price point, reflecting its additional capabilities and luxury touches.


Conclusion


In summary, the choice between the Lexus NX 300h and NX 350h ultimately depends on your priorities. If you value fuel efficiency and a lower price, the NX 300h is an excellent choice. However, if you seek a more powerful hybrid with advanced features and a dynamic driving experience, the NX 350h is worth the investment. Whichever model you choose, both offer the luxury and reliability that Lexus is known for.
