Those prices line up with size: the UX is the subcompact, the NX the compact, and the RX the midsize. Shoppers cross-shop all three because they wear the same badge and the same design language, yet they sit on different footprints, hold different amounts of cargo, and take different positions on gas versus hybrid.Size And DimensionsThe UX 300h and RX 350 sit 15.5 inches apart in length, one a subcompact and the other a midsize, with the NX 350 splitting the difference. Two of the figures below break that order.DimensionUX 300hNX 350RX 350Length177.0 in183.5 in192.5 inWheelbase103.9 in105.9 in112.2 inWidth72.4 in73.4 in75.6 inHeight60.6 in66.1 in67.3 inCargo, behind rear seats17.1 cu ft22.7 cu ft29.6 cu ftCargo, seats foldednot published46.9 cu ft46.2 cu ftLegroom, front / rear42.0 / 33.1 in41.0 / 36.1 in41.1 / 37.4 inShoulder room, rear52.9 in54.0 in56.5 inHip room, rear52.3 in52.5 in56.0 inCurb weight, base3,455 lb4,035 lb4,155 lbFuel tank10.6 gal14.5 gal17.8 galExterior FootprintThe UX 300h turns in a 34.2-foot circle, nearly four feet tighter than the NX 350, and it is short enough to fit street spaces and older garages the far longer RX 350 cannot. The RX spends its extra length on cabin and cargo rather than front and rear overhang, which is why it alone reads as a true midsize SUV. The NX 350 lands close enough to the UX in footprint to stay easy to park.LexusView the 3 images of this gallery on the original articleCargo SpaceFold the second row and the RX 350's cargo lead nearly disappears: it holds slightly less maximum space than the NX 350, as the table shows. Its advantage is really the room behind a raised second row, which is how most owners load it. Lexus does not publish a seats-folded number for the UX 300h, so its maximum stays out of this comparison.Lexus UX CargoLexusView the 3 images of this gallery on the original articlePassenger RoomThe RX 350's rear hip room is three and a half inches wider than either sibling's, enough that it alone seats three adults across the back without complaint. The UX 300h and NX 350 are effectively four-passenger vehicles on a long drive, and rear legroom follows the same order, favoring the RX by a smaller margin. Front-seat space is within an inch across all three.2026 Lexus UXLexusView the 3 images of this gallery on the original articleWeight, Fuel, And RangeCurb weight rises with size as expected, from 3,455 pounds for the UX 300h to 4,155 for the RX 350, but range ignores that order. The UX and RX both cover roughly 450 miles on a tank, while the compact NX 350 between them manages only about 350, because its gas turbo is the thirstiest of the three and its 14.5-gallon tank is barely larger than the subcompact UX's.The Price LadderA fully loaded UX 300h runs $42,685 in F SPORT Design, still less than a base NX 350, and a top NX 350 in Luxury trim ($53,285) costs about what a mid-level RX 350 does. Only the NX and RX ranges truly meet, around the $53,000 mark.AdvertisementAdvertisementThe NX 350 gas comes only with all-wheel drive, while the UX 300h and RX 350 start front-wheel drive and charge $1,570 and $1,600 respectively to add it. For a buyer set on all-wheel drive, that shrinks the real gap between a base NX and a base RX to under $6,000.Where The Ladder Inverts On FuelThe UX 300h returns 43 mpg combined on regular gasoline, nearly double what the gas NX 350 and RX 350 manage on the premium they require. Both larger models use the 2.4-liter turbocharged four rated at 275 hp and 317 lb-ft, and both are EPA-rated at 24 mpg combined with all-wheel drive, with the RX reaching 25 in front-drive form.Run those figures through the EPA's reference prices of $3.99 a gallon for regular and $4.61 for premium, over a 15,000-mile year, and the UX 300h costs about $1,400 to fuel against roughly $2,880 for the gas NX and RX, close to $1,500 more a year and about $7,400 more across five. Buyers who want the space without the fuel bill can order either larger model as a hybrid, the RX 350h at 36 mpg combined or the NX 350h at 40.The gas NX 350 reaches 60 mph in 6.6 seconds, quickest of the three, ahead of the RX 350 at 7.2 and the UX 300h at 7.9. Owners of the gas cars should also note a March 2026 recall covering certain non-hybrid NX, RX, and TX models, for a backup-camera display that can go blank in reverse; the remedy is a free software update or camera replacement.AdvertisementAdvertisementRelated: Lexus Recalls NX, RX, TX Amid Surge in Backup Camera FailuresCabin And FeaturesAll three carry wireless Apple CarPlay and Android Auto, dual-zone climate control, power-adjustable front seats, and Lexus Safety System+ as standard. Infotainment grows with the car, from the UX 300h's 8.0-inch Lexus Interface screen to the NX 350's 9.8-inch unit. The RX 350 adds a 40/20/40-split rear seat with a center pass-through the smaller two lack, letting it carry long items and rear passengers at once.2026 Lexus NX 350LexusWhich One Is For YouFor most shoppers, the NX 350 is the pick. It is a size up from the UX 300h without the RX 350's midsize footprint or its premium, and standard all-wheel drive makes its higher starting price easier to justify. Anyone bothered by its 24-mpg gas thirst can order the NX 350h and give up nothing else. The UX 300h earns a look below it only from city drivers who value easy parking and low running costs over rear-seat room. The RX 350's premium makes sense just for buyers who regularly fill the cargo hold or seat three abreast, the one thing its longer wheelbase and wider rear bench do better than either sibling.This story was originally published by Autoblog on Jul 20, 2026, where it first appeared in the Features section.
