2026 Lexus RX 350 vs. 2026 Mercedes-Benz GLE: Luxury Midsize SUV Comparison
The 2026 Lexus RX 350 and the 2026 Mercedes-Benz GLE sit in the same midsize luxury class. They aim at different buyers. This comparison puts the gas-powered RX 350 against the full GLE SUV lineup across powertrains, fuel economy, cargo and capability, cabin technology, safety, and warranty coverage, so you can see where each one earns its keep.
Powertrain and Performance
Every 2026 Lexus RX 350 uses the same engine. It is a 2.4-liter turbocharged four-cylinder making 275 horsepower and 317 lb-ft of torque, paired with an eight-speed automatic transmission. Front-wheel drive is standard. All-wheel drive is available on every grade, and it is standard on F SPORT Handling.
The RX 350 reaches 60 mph in 7.6 seconds with front-wheel drive and 7.2 seconds with all-wheel drive. That is enough for confident freeway merging without the engine working hard.
The Mercedes-Benz GLE starts lower and climbs much higher. The entry GLE 350 produces 255 horsepower from a 2.0-liter turbocharged four-cylinder with mild-hybrid assist. It uses a nine-speed 9G-TRONIC automatic, and rear-wheel drive is standard. From there the range extends through an inline-six, a plug-in hybrid, a V8, and two Mercedes-AMG models.
| Specification | 2026 Lexus RX 350 | 2026 Mercedes-Benz GLE 350 |
|---|---|---|
| Engine | 2.4L turbocharged inline-4 | 2.0L turbocharged inline-4, mild hybrid |
| Horsepower | 275 hp | 255 hp |
| Torque | 317 lb-ft | 295 lb-ft |
| Transmission | 8-speed automatic | 9G-TRONIC 9-speed automatic |
| Drivetrain | Front-wheel drive standard, AWD available | Rear-wheel drive standard, 4MATIC AWD available |
| 0-60 mph | 7.6 sec FWD / 7.2 sec AWD | Not published by Mercedes-Benz for this model year |
Against the GLE 350, the RX 350 holds a 20-horsepower and 22 lb-ft advantage. Against the upper GLE models it does not compete on output. It is not meant to.
How the Lineups Compare
2026 Lexus RX 350 Grades
The RX 350 comes in six grades. Every one uses the same 275-horsepower turbocharged engine. The choice comes down to equipment, styling, and whether you want all-wheel drive.
- Standard — the foundation grade
- Premium
- Premium+
- Luxury
- F SPORT Design — adds the sport-styled exterior treatment
- F SPORT Handling — adds an adaptive suspension, and comes only with all-wheel drive
The RX nameplate also extends past the gas model into three electrified powertrains. The RX 350h hybrid, the RX 450h plug-in hybrid, and the RX 500h F SPORT Performance all fall outside this comparison. If efficiency is your priority, those are worth a look alongside the RX 350. The full grade and powertrain breakdown is published on the Lexus USA newsroom 2026 RX page.
2026 Mercedes-Benz GLE Lineup
The GLE SUV lineup spans six powertrains. It is broader than most shoppers expect.
| Model | Engine | Horsepower | Torque |
|---|---|---|---|
| GLE 350 / GLE 350 4MATIC | 2.0L turbo inline-4, mild hybrid | 255 hp | 295 lb-ft |
| GLE 450 4MATIC | 3.0L turbo inline-6, mild hybrid | 375 hp | 369 lb-ft |
| GLE 450e 4MATIC | 2.0L turbo inline-4 plug-in hybrid | 381 hp combined | 479 lb-ft |
| GLE 580 4MATIC | 4.0L twin-turbo V8, mild hybrid | 510 hp | 538 lb-ft |
| Mercedes-AMG GLE 53 | 3.0L turbo inline-6, mild hybrid | 429 hp | 413 lb-ft |
| Mercedes-AMG GLE 63 S | 4.0L twin-turbo V8, mild hybrid | 603 hp | 627 lb-ft |
That range is the GLE’s real argument. It opens with a four-cylinder that undercuts the RX 350 on power. It tops out with a V8 that no Lexus RX answers. A shopper cross-shopping these two is choosing between one well-sorted configuration and a menu.
EPA-Estimated Fuel Economy and Range
The RX 350 is the more efficient choice against comparable GLE models. The margin narrows at the bottom of the Mercedes-Benz range. It reverses entirely against the GLE plug-in hybrid.
| Model | EPA-Estimated City | EPA-Estimated Highway | EPA-Estimated Combined |
|---|---|---|---|
| Lexus RX 350 FWD | 22 mpg | 29 mpg | 25 mpg |
| Lexus RX 350 AWD | 21 mpg | 28 mpg | 24 mpg |
| Mercedes-Benz GLE 350 (RWD) | 21 mpg | 28 mpg | 23 mpg |
| Mercedes-Benz GLE 350 4MATIC | 19 mpg | 26 mpg | 22 mpg |
| Mercedes-Benz GLE 450 4MATIC | 19 mpg | 25 mpg | 21 mpg |
| Mercedes-AMG GLE 53 | 18 mpg | 23 mpg | 20 mpg |
| Mercedes-AMG GLE 63 S | 15 mpg | 20 mpg | 17 mpg |
EPA-estimated fuel economy figures are for comparison purposes only. Your actual mileage will vary depending on driving conditions, how you drive and maintain your vehicle, battery age/condition, and other factors.
Compared like for like with all-wheel drive, the RX 350 AWD returns 24 mpg combined. The GLE 350 4MATIC returns 22 mpg combined. The gap widens as you move up the GLE range.
The RX 350 carries a 17.8-gallon tank. That gives it an EPA-estimated total driving range of 445 miles in front-wheel drive and 427 miles with all-wheel drive. Both configurations require premium unleaded gasoline, and so does the GLE 350. These figures are published by the EPA on the fueleconomy.gov 2026 Lexus RX 350 listing. For a breakdown across every 2026 RX powertrain, including the hybrid grades, see our 2026 Lexus RX MPG guide.

Space, Cargo, and Capability
This is the clearest split between the two. The RX 350 is the lighter, tidier vehicle. The GLE is the bigger, more capable one.
| Specification | 2026 Lexus RX 350 | 2026 Mercedes-Benz GLE |
|---|---|---|
| Curb weight | 4,155 lbs | 5,060–5,567 lbs |
| Seating capacity | 5 | 5 standard, 7 with optional third row |
| Cargo behind second row | 29.6 cu ft | 33.3 cu ft |
| Maximum cargo volume | 46.2 cu ft | 74.9 cu ft |
| Maximum towing capacity | 3,500 lbs | 7,700 lbs |
Maximum towing and payload capacity figures are based on properly equipped vehicles and vary by configuration. Do not exceed any weight rating. See your owner’s manual and the vehicle’s door-jamb label for specific capacities.
The RX 350 is roughly 900 to 1,400 pounds lighter than the GLE, depending on configuration. That makes it easier to place in a tight parking structure. It also settles more quickly over broken pavement.
The trade-off is real. The GLE offers more cargo room behind its second row, far more with the seats folded, an optional third row the RX does not offer at all, and more than double the towing capacity. If you regularly tow or need seven seats, the GLE is the correct answer, and it is not close.
Front occupants in the RX 350 get heated front seats as standard. Ventilated front seats are available higher in the range. An available 40/20/40 split-folding second row lets you extend cargo length without giving up a rear passenger seat.

Technology Inside the Cabin
The RX 350 runs the Lexus Interface multimedia system. A 9.8-inch touchscreen is standard, and a 14-inch display is standard on the upper grades rather than bundled into an add-on package. A 12.3-inch multi-information display sits in the driver’s line of sight.
A 12-speaker audio system is fitted across most of the range. Wireless phone charging became standard across the entire RX lineup for 2026. An available Digital Key lets a compatible smartphone operate the vehicle through the Lexus app. Apple CarPlay and Android Auto are standard.
The GLE uses the MBUX infotainment system. Both cabins are well built and well equipped. The practical difference is that the Lexus arrives with more of its technology fitted as standard at the entry grade, while the Mercedes-Benz rewards shoppers willing to climb the range. A closer look at the RX cabin is in our 2026 Lexus RX interior and technology overview.
Safety Systems
Lexus Safety System+ 3.0 is standard on every 2026 RX grade at no extra cost. The suite includes a Pre-Collision System with Pedestrian Detection. It also adds dynamic radar cruise control, lane-centering support, and parking aids.
IIHS Crash Test Results
The Insurance Institute for Highway Safety has published a full set of results for the 2026 RX. They are mixed, and they are worth reading before you buy.
| IIHS Evaluation | 2026 Lexus RX Rating |
|---|---|
| Small overlap front | Good |
| Moderate overlap front (updated test) | Poor |
| Side (updated test) | Good |
| Headlights | Good |
| Pedestrian front crash prevention (standard) | Good |
| Child seat anchors (LATCH ease of use) | Good |
The 2026 RX does not hold an IIHS Top Safety Pick award. The Poor result in the updated moderate overlap front test is driven by rear-passenger measures, and IIHS raised the bar for 2026 by requiring a Good rating in that test for either award level. You can review the complete record on the IIHS 2026 Lexus RX ratings page.
NHTSA Ratings
The National Highway Traffic Safety Administration rates the 2026 RX 350 with all-wheel drive at five stars overall. The front-wheel-drive model receives four stars overall. Both earn five stars in the side crash test, and four stars in the frontal crash and rollover tests.
Crash-test programs change year to year. Check current IIHS and NHTSA results for both the RX and the GLE before you decide.

Warranty Coverage
This is where the Lexus advantage is clearest and easiest to verify.
| Coverage | 2026 Lexus RX 350 | 2026 Mercedes-Benz GLE |
|---|---|---|
| Basic / new vehicle limited warranty | 48 months / 50,000 miles | 48 months / 50,000 miles |
| Powertrain warranty | 72 months / 70,000 miles | 48 months / 50,000 miles |

Mercedes-Benz does not separate powertrain coverage from its New Vehicle Limited Warranty. Engine, transmission, and drivetrain protection ends at 48 months or 50,000 miles along with everything else. Lexus continues powertrain coverage for a further 24 months and 20,000 miles.
For an owner who keeps a vehicle past the fourth year, that gap is the single largest ownership-cost difference between these two SUVs.
