The body dimensions of the RX are: length 4890mm, width 1895mm, height 1710mm, with a wheelbase of 2790mm. Its fuel tank capacity is 72.5 liters, and the luggage compartment volume ranges from 506 to 1579 liters, making it a mid-to-large 5-door, 5-seat SUV. The Lexus RX is equipped with a 2.0T turbocharged engine and a 6-speed automatic transmission, delivering a maximum power of 170 kW at 5200-5600 rpm and a maximum torque of 350 Nm. It features front-wheel drive, with a front MacPherson strut independent suspension and a rear double-wishbone independent suspension.

Recently while helping a friend check out cars, I happened to measure the dimensions of the RX. This generation (2023 model) has a length of 4.89 meters, nearly 5 meters long. The width was most surprising - with mirrors fully extended it reaches 1.92 meters, but the folded mirror width of 1.92 meters is more practical for daily parking. The roof rail version stands over 1.7 meters tall, offering exceptional headroom inside where legs can stretch out completely. The 2.85-meter wheelbase significantly improves rear seat comfort - last time I gave three coworkers a ride home, they all commented it was more spacious than expected. The trunk depth can vertically accommodate a stroller, making it perfectly sufficient for weekend outings with kids.

While studying the RX specifications, I noticed a detail: the fifth-generation body is 6 cm longer than the previous model, but the clever design actually results in a smaller turning radius. In practice, it doesn't feel bulky at all—just one and a half turns of the steering wheel is enough to make a U-turn. As for storage capacity, with the rear seats folded down, it can fit my entire camping gear plus a folding bicycle. Last time, I even helped my roommate move a 1.8-meter floor mirror. One thing to note is that the vehicle width data includes the side mirrors, so if a mall's mechanical parking space has a limit of under 1.9 meters, you’ll need to fold the mirrors carefully. In terms of weight, the hybrid version is just over two tons, while the gasoline-only version is about 200 kg lighter.

Last week during the test drive, I specifically noted the dimensions: the standard version measures 489019201695mm, while the sport version is 1cm shorter but appears more aggressive. The most immediate impression upon sitting inside was that even with the driver's seat adjusted to its lowest position, there was still a fist and a half of headroom. The rear seats can comfortably accommodate three men weighing 80kg each without feeling cramped, and the center armrest can be lowered to serve as a temporary workspace. It's worth noting that the F SPORT version has a 15mm lower chassis, requiring slower speeds over speed bumps. The wheels come in both 21-inch and 20-inch options, with a significant price difference when replacing tires.

Comparing the dimensions of three generations of RX, the current model is nearly 30 cm longer than the first generation! With the widened chassis in this generation, cornering is indeed more stable, and it doesn’t feel floaty when driving on the highway during heavy rain. When loading skis, you can fold down the right-side second-row seat with one touch to fit 1.9-meter-long twin skis without removing the bindings. Once, I helped a client transport display boards by removing the cargo cover and barely managed to fit a 2-meter-long box. One downside is that the automatic parking system has high requirements for parking space length—it only recognizes spaces that are 5.2 meters long. The hybrid version’s is under the rear seat, which doesn’t encroach on the trunk space but raises the floor by 3 cm.

As an engineer who frequently disassembles luxury cars, I particularly admire the RX's short overhangs design—squeezing out a 2.85-meter wheelbase within a 4.9-meter body length. The 59-degree windshield inclination and 15-degree rear spoiler angle achieve a drag coefficient of 0.33, making it exceptionally fuel-efficient at high speeds. The inward-tapered lower door design allows the actual passing width to be narrower than the specs, easily clearing 1.8-meter bollards in old neighborhoods. The body uses 94% high-strength steel yet achieves better weight control than German counterparts. The air suspension-equipped version can lower the ride height by 2 cm, making underground garage access even more convenient.
