The Lexus NX and RX are both popular luxury SUVs from the renowned Japanese automaker, but they cater to different segments of the market. The NX is a compact crossover SUV, while the RX is a midsize SUV. Both vehicles offer premium features, advanced technology, and Lexus’ signature build quality, but they differ in size, performance, and pricing.
The Lexus NX, introduced in 2014, is designed for urban drivers who want a luxurious compact SUV with agile handling and efficient powertrains. The RX, on the other hand, has been a staple in the Lexus lineup since 1998 and offers more space, power, and comfort for families or those who prefer a larger vehicle. Let’s dive into the key differences between these two Lexus SUVs.
| Feature | Lexus NX | Lexus RX |
|---|---|---|
| Size | Compact SUV | Midsize SUV |
| Length | 183.5 inches | 192.5 inches |
| Starting Price (2025) | $41,965 | $49,950 |
| Base Engine | 2.5L I4 (203 hp) | 2.4L Turbo I4 (275 hp) |
Size and Dimensions
One of the most noticeable differences between the Lexus NX and RX is their size. The NX is significantly smaller than its RX sibling, making it more suitable for urban environments and tight parking spaces. The 2025 Lexus NX measures 183.5 inches in length, 73.4 inches in width, and 65.8 inches in height. In contrast, the 2025 Lexus RX is 192.5 inches long, 75.6 inches wide, and 67.3 inches tall.
The size difference is also reflected in the interior space. The RX offers more passenger room, especially in the rear seats, and has a larger cargo capacity. The NX provides 46.9 cubic feet of maximum cargo space with the rear seats folded, while the RX offers up to 46.2 cubic feet. Despite the RX being larger overall, the NX surprisingly has a slightly larger maximum cargo capacity, which is worth noting for those who prioritize storage space.
The wheelbase of the RX is also longer at 112.2 inches compared to the NX’s 105.9 inches. This longer wheelbase contributes to the RX’s smoother ride and more spacious interior. However, the NX’s shorter wheelbase makes it more maneuverable in tight spaces, which is a significant advantage for city driving.
Performance and Powertrains
Both the Lexus NX and RX offer a range of powertrain options, including hybrid variants, but there are notable differences in their performance characteristics.
The 2025 Lexus NX starts with a 2.5-liter four-cylinder engine producing 203 horsepower in the base NX 250 model. The NX 350 upgrades to a 2.4-liter turbocharged four-cylinder with 275 horsepower. For those seeking better fuel efficiency, the NX 350h hybrid combines a 2.5-liter engine with electric motors for a total output of 240 horsepower.
In comparison, the 2025 Lexus RX base model (RX 350) comes standard with a 2.4-liter turbocharged four-cylinder engine generating 275 horsepower. The RX 350h hybrid uses a similar setup to the NX but produces 246 horsepower. For performance enthusiasts, the RX 500h F Sport Performance offers a more powerful hybrid system with 366 horsepower.
The RX generally provides more powerful engine options and a smoother ride due to its larger size and longer wheelbase. However, the NX offers better fuel economy in its base and hybrid models, making it a more economical choice for daily commuting.
Interior and Technology
Both the Lexus NX and RX feature luxurious interiors with high-quality materials and advanced technology. However, there are some differences in their layouts and available features.
The NX, being a newer design, comes with Lexus’ latest infotainment system featuring a standard 9.8-inch touchscreen or an optional 14-inch touchscreen. The RX also offers the 14-inch screen but comes standard with a slightly smaller display. Both models support Apple CarPlay and Android Auto integration.
In terms of seating, the NX is strictly a five-passenger vehicle, while the RX is available in both five-seat and seven-seat configurations (in the RX L variant). The RX offers more legroom and headroom, especially for rear passengers, making it more comfortable for long trips or for families with taller occupants.
Both SUVs come equipped with Lexus Safety System+ 3.0, which includes features like:
- Pre-collision system with pedestrian detection
- Lane departure alert with steering assist
- Dynamic radar cruise control
- Road sign assist
The RX, being the more premium model, may offer some additional luxury features or more upscale trim options compared to the NX.
Pricing and Value
The Lexus NX and RX target different price points, reflecting their size and positioning in the luxury SUV market. The 2025 Lexus NX has a starting MSRP of $41,965 for the base NX 250 FWD model. As you move up the trim levels and add options, the price can increase significantly, especially for the hybrid and F Sport models.
In contrast, the 2025 Lexus RX starts at $49,950 for the base RX 350 FWD model. The higher starting price reflects the RX’s larger size, more powerful base engine, and additional features. The top-tier RX models, particularly the hybrid variants, can exceed $60,000 with options.
While the RX is more expensive, it offers more space, power, and luxury features. The NX provides a more affordable entry point into the Lexus SUV lineup without sacrificing too much in terms of quality and features. The choice between the two often comes down to budget, size requirements, and personal preferences.
Fuel Economy and Efficiency
Fuel efficiency is an important consideration for many SUV buyers. The Lexus NX generally offers better fuel economy across its range compared to the RX, thanks to its smaller size and more efficient base engine.
The 2025 Lexus NX 250 FWD achieves an EPA-estimated 26 mpg city and 33 mpg highway. The hybrid NX 350h improves these figures significantly, offering 41 mpg city and 37 mpg highway. These numbers make the NX an excellent choice for those prioritizing fuel efficiency in their luxury SUV.
The 2025 Lexus RX, being larger and more powerful, has slightly lower fuel economy ratings. The base RX 350 FWD is rated at 22 mpg city and 29 mpg highway. The RX 350h hybrid improves efficiency with 37 mpg city and 34 mpg highway.
While the RX’s fuel economy is respectable for its class, the NX clearly has an advantage in this area, especially with its hybrid variants. This difference can lead to significant fuel cost savings over time, particularly for drivers with long commutes or those who do a lot of city driving.
