The main difference between Lexus NX 300 and RX 350 include size, powertrain, available seating, key features, and fuel efficiency. Lexus RX 350 is a more powerful and larger SUV, but NX 300 offers more advanced features. The better option between the two depends on your needs and requirements.

You can enjoy luxury rides with both SUVs, and they offer room for five passengers. However, their differences are the main things every potential buyer should consider. To help you understand these differences, we’ll closely look at each of them below.

– Size

The most notable difference between the two SUVs is their size. With RX 350, you get more room for cargo and passengers than the NX 300. This implies that the RX 350 will allow you to haul more and ensure that your passengers enjoy more comfort.

Even though the standard option available on both vehicles is five seats, RX offers a 350L trim level, which comes with a third-row seat. Therefore, the vehicle can accommodate up to seven passengers. This option is not available on NX 300 counterparts.

– Engine

The next distinguishing feature of the two vehicles is the engine they come with. With the NX 300, you get a 2.0L 4-cylinder engine, while RX 350 features the 3.5L V6 engine from Lexus. Therefore, you get more torque and horsepower with RX 350 than NX 300.

Despite the higher power offered by the engine of the RX 350, the difference isn’t always noticed by most drivers. This is due to the larger size of the RV SUV, and even though it has a V6 engine, the handling of both vehicles is very similar.

– Fuel Efficiency

Every driver looks out for fuel-efficient alternatives when buying a car, considering the rising price of fuel. This is also an area that differentiates the two Lexus models. The EPA mileage estimate of the RX 350 is 27 mpg when driving on the highway and 20 mpg for city driving. This results in a combined mpg of 23 for RX 350.

It’s a lot better with the NX 300 counterpart, as the EPA mileage estimate for city driving is 22 mpg, and for highway driving is 28 mpg. Therefore, you can get up to 25 mpg combined fuel economy with the NX 300.

The figure is higher for NX 300, which indicates better fuel efficiency than the RX counterpart. Therefore, you can expect your fuel to last longer with the NX.

– Towing Capacity

Are you considering using your SUV to tow? Then the towing capacity of both vehicles is a factor to consider. Consider the RX 350 if you have a heavier load to haul because it offers up to 3,500 lbs. towing capacity. On the other hand, the maximum towing capacity of NX 300 is 2,000 lbs. which makes it unsuitable for towing heavier loads.

– Interior Options and In-Car Entertainment

In addition, you get nine speakers with RX 350 and eight with NX 300. Other features they offer include satellite radio with real-time traffic alerts, aux cable input, and a memory card slot.

– Transmission

Transmission is also a factor that sets the two vehicles apart. With the NX 300, you get 6-speed shiftable automatic transmission while the RX 350 offers 8-speed shiftable automatic transmission. Even though they have different transmissions, it’s important to note that both vehicles come with an FWD drivetrain and they run on gas.

– Overall Comparison

With everything above, it’s clear that the RX 350 is a better option, especially if you’re looking for a larger SUV. The RX 350 provides the option to upgrade the seat configuration from the conventional five to seven, which is not the case with NX 300.
