Acura ADX vs. Lexus UX 300h: Which Luxury Compact SUV Wins?

Shoppers cross-shopping the Acura ADX and Lexus UX 300h are almost always comparing two spec sheets that look close on price but live very differently once you’re loading cargo, buckling in a booster seat, or filling up on a Tuesday. This comparison lines up the numbers that actually decide it, cargo room, rear-seat space, fuel economy, standard features, safety, and price, pulled straight from published Acura and Lexus data, so you can settle the question before you ever set foot on a lot.

The 2026 Acura ADX beats the 2026 Lexus UX 300h on cargo room, rear legroom, and starting price, giving Lafayette drivers about 42 percent more cargo space and $2,400 in savings, while the UX 300h’s real edge comes down to hybrid fuel economy at an EPA-estimated 43 mpg combined. Both are entry points into their respective luxury brands for the 2026 model year. 

At Acura of Lafayette, our team fields this exact matchup from shoppers across Lafayette, Broussard, Scott, Youngsville, and as far out as Baton Rouge and Lake Charles, often multiple times a week. This guide walks through every category side by side, cargo and legroom, drivetrain feel, fuel economy, standard equipment, and total cost, so you leave knowing exactly which one matches how you actually use an SUV.

Key Points: Acura ADX vs. Lexus UX 300h

• The ADX gives you real room to work with. 24.4 cubic feet of cargo space and 37.7 inches of rear legroom outclass the UX 300h, about 42 percent more cargo room and 4.6 more inches of legroom for anyone riding in back.
• You get more vehicle for less money. The 2026 ADX starts at $36,450, about $2,400 under the UX 300h, and comes standard with a 9-inch touchscreen, heated front seats, and a power moonroof, equipment the UX 300h doesn’t match anywhere close to that price.
• The UX 300h’s mpg edge doesn’t always pay for itself. Its hybrid powertrain returns an EPA-estimated 43 mpg combined against the ADX’s 28 mpg, but at typical Lafayette-area mileage that fuel savings takes years to close the ADX’s $2,400 price gap, so room and price usually decide it first.

Acura ADX vs. Lexus UX 300h: The Numbers Side by Side

Starting MSRP figures are before options, taxes, title, license, and dealer fees, and are shown for reference only. Fuel economy figures for both vehicles are EPA estimates, Lexus carries over its 2025 EPA ratings for the 2026 UX 300h, and Acura of Lafayette can confirm current pricing and availability.

Does the Acura ADX Have More Room Than the Lexus UX 300h?

Cargo room is where the Acura ADX and the Lexus UX 300h separate most clearly. The ADX offers 24.4 cubic feet behind the second row, expanding to 55.1 cubic feet with the 60/40 split seats folded. The UX 300h offers approximately 17.1 cubic feet behind its rear seats. The ADX holds about 42 percent more, and you feel it on a single grocery run.

Rear legroom follows the same pattern. The ADX measures 37.7 inches in the second row against roughly 33.1 inches in the UX 300h. Those 4.6 inches separate adults riding comfortably from adults negotiating. The ADX is also 8.8 inches longer overall, so measure your garage first if space at home is tight.

Which Drives Better, the Acura ADX or the Lexus UX 300h?

The Acura ADX and the Lexus UX 300h are tuned for two different drivers. Acura built the ADX on the same platform as the Integra. The ADX gets a sport-tuned independent suspension, dual-pinion electric power steering, and an aluminum front subframe for rigidity. Its 1.5-liter VTEC Turbo is a variant of the Integra engine, rated at 190 horsepower and 179 lb-ft of torque from 1,700 rpm. That flat torque curve makes the ADX feel eager at the speeds you actually drive.

Sport mode sharpens throttle response and adds steering feedback. The available all-wheel drive sends up to half the power rearward to help the ADX turn. A-Spec trims add 19-inch wheels, a flat-bottom steering wheel, and sport pedals. Paddle shifters and four drive modes come standard, with Individual mode on A-Spec Advance.

The Lexus UX 300h takes the other path. Its 2.0-liter engine and two electric motors make 196 total system horsepower. Lexus estimates 0 to 60 mph in 7.9 seconds with all-wheel drive. Lexus tunes the UX 300h for quiet over sharp, which is the right call if calm is what you want from a commute.

Both offer all-wheel drive at every trim. The ADX also rides 7.3 inches off the pavement, which helps on steep driveways.

Lexus UX 300h Fuel Economy vs. Acura ADX Efficiency

The Lexus UX 300h is a hybrid and the Acura ADX is not. The UX 300h is EPA-estimated at 43 mpg combined with front-wheel drive and 42 mpg combined with all-wheel drive.

The ADX carries a 2026 EPA rating of 28 mpg combined with front-wheel drive and 27 mpg combined with all-wheel drive. Those are respectable numbers for a turbocharged gas SUV, but they do not match a hybrid.

Run the math against your own driving. At 15,000 miles a year, the UX 300h saves roughly 185 gallons of fuel compared with the ADX. Drivers making the I-10 run to Baton Rouge or Lake Charles feel that gap sooner than drivers who stay inside Lafayette.

Inside the Acura ADX and Lexus UX 300h

Every 2026 Acura ADX includes a 9-inch touchscreen, a 10.2-inch digital driver display, wireless Apple CarPlay and Android Auto, and a wireless phone charger. Heated front seats, dual-zone automatic climate control, rear air vents, and a power moonroof are standard even on the base trim. The A-Spec with Advance Package adds Google built-in, a 15-speaker Bang & Olufsen system, and leather-trimmed seats.

The Lexus UX 300h opens with an 8-inch touchscreen and moves to a 12.3-inch screen on the F SPORT Handling grade. Its NuLuxe seating and washi-inspired dash trim give the cabin a calm, finished feel. The ADX puts more equipment in the base trim, while the UX 300h leans harder on material quality.

Safety You Do Not Have to Upgrade To

The Acura ADX and the Lexus UX 300h both include their full driver-assist packages on the base trim, with no package to add. AcuraWatch covers collision mitigation braking, adaptive cruise control with low-speed follow, lane keeping assist, blind spot information, cross traffic monitor, and traffic jam assist. Lexus Safety System+ 3.0 covers pre-collision braking with pedestrian detection, lane tracing assist, road sign assist, and proactive driving assist.

The ADX earned an IIHS TOP SAFETY PICK award, and the rating applies to 2025 and 2026 models. It also earned a 5-star Overall Vehicle Score from NHTSA. Warranty terms match at 4 years or 50,000 miles basic and 6 years or 70,000 miles powertrain. Lexus adds hybrid battery coverage for 10 years or 150,000 miles, which protects the priciest part of a hybrid.

Acura ADX vs. Lexus UX 300h: Pricing and Value

The 2026 Acura ADX starts at $36,450, which includes the $1,450 destination charge. The 2026 Lexus UX 300h starts at $38,850, which includes its $1,395 delivery, processing and handling fee. Both figures cover front-wheel-drive base models before options, taxes, and fees.

Value depends on what you count. The ADX asks about $2,400 less up front and gives you more usable space for the money. The UX 300h asks more at the start and returns some of it at the pump.

The real test is your annual mileage. Under roughly 12,000 miles a year, the fuel savings take a long time to close a $2,400 gap. Above 20,000 miles, the math shifts toward the hybrid. Acura of Lafayette on Johnston Street sits a short drive from Broussard, Scott, and Youngsville. Come sit in an ADX and check the numbers against your own routine.
