The differences between RX and NX are: 1. The 0-100 km/h acceleration time is different: Lexus RX takes 8 seconds; Lexus NX takes 9.2 seconds. 2. The fuel tank capacity is different: Lexus RX has a 65-liter fuel tank; Lexus NX has a 56-liter fuel tank. 3. The body dimensions are different: Lexus RX measures 5000mm in length, 1895mm in width, and 1720mm in height, with a wheelbase of 2790mm; Lexus NX measures 4640mm in length, 1845mm in width, and 1645mm in height, with a wheelbase of 2660mm.

When I changed cars the year before last, I test drove every model in the showroom, and the RX and NX drove completely differently. The RX feels like a mobile living room inside, with rear seats spacious enough to cross your legs. The hybrid version's engine noise is almost inaudible during acceleration, and the chassis is as stable as a high-speed train on long trips. The NX's rear seats feel cramped with three adults, and the hybrid version's engine roar is particularly noticeable, but it's really convenient for city parking—narrow alleys are a breeze. In terms of price, the RX hybrid starts at over 600,000 RMB out the door, while the top-tier NX hybrid can be driven away for 500,000 RMB. In the end, I chose the RX because my son can spread out a picnic mat in the trunk during family trips.

Last week, I thoroughly researched while accompanying my best friend to order an NX. The most obvious differences between these two cars are their size and class. The RX is nearly 5 meters long with a wheelbase exceeding 2.8 meters, making it a standard mid-to-large luxury SUV; the NX is just over 4.6 meters long, belonging to the compact category. My best friend chose the NX300h hybrid mainly because it's easier to park, as her company's underground parking spaces are narrow. But when it comes to presence, the RX is stronger. That day, I saw a new RX500h Sport version with a spindle grille and 21-inch wheels, and the X5 parked next to it suddenly didn't seem as appealing. However, the RX hybrid still consumes about 7L per 100 km, while the NX only needs a little over 5L.

Let's get straight to the key differences: First, there's a significant size gap – the RX is over 30cm longer than the NX, putting them in different classes. Second, the RX exclusively offers hybrid powertrains (2.5L/2.4T hybrid), while the NX has a more affordable 2.0L pure gasoline option. Third, major power disparity – the RX450h+ delivers 273hp versus the NX350h's 239hp. Fourth, tech features: the new RX comes with electronic door handles and smartphone key as standard, whereas only the top-trim NX gets these. In short: choose the RX for a premium large 5-seater, or opt for the NX entry model at around 400k RMB for better value.

As a two-generation owner, the RX is the true luxury SUV experience. It comes standard with double-layer soundproof glass and a Mark Levinson audio system with 21 speakers, reducing tire noise at 120 km/h by half compared to the NX. The rear seats feature heating, and the new model even includes vibration-alert seatbelts. However, the NX has caught up with the RX in terms of intelligent driving, with the latest LSS+3.0 system supporting predictive pedestrian detection. The main drawback of the NX is its 2.5L hybrid paired with a CVT transmission—during rapid acceleration, the engine revs skyrocket, whereas the RX's 2.4T hybrid with a 6AT is much smoother. That said, the NX is undeniably nimble, making it a master at snagging parking spots in crowded markets.
