Lexus is Toyota's luxury division, but Toyota often builds a Lexus-badged twin to capture buyers who want that extra refinement without the higher sticker price. The Grand Highlander and the Lexus TX mimic that pattern as closely as any two vehicles have. Both are three-row midsize SUVs, both ride on a version of the same platform, and both come from the same Toyota Motor Manufacturing plant in Princeton, Indiana.
That much shared DNA raises the question of whether going for the Lexus is actually worth it.
The 2026 Toyota Grand Highlander starts at $43,855, including the $1,595 destination charge. By contrast, the 2026 Lexus TX 350 starts at $58,490, including the $1,550 destination charge. The difference in starting MSRP between the two SUVs lands around $14,600.
Nearly the same engine lineup
Different outputs on paper
The 2026 Toyota Grand Highlander offers three powertrains. The base gas engine is a 2.4-liter turbocharged four-cylinder making 265 horsepower and 310 lb-ft. of torque paired to an eight-speed automatic.
The Grand Highlander Hybrid has a 2.5-liter four-cylinder with an electric motor, producing 245 net combined horsepower, paired with a continuously variable transmission. At the top sits the Hybrid MAX powertrain, combining a 2.4-liter turbo four with an electric motor for 362 net combined horsepower and 400 lb-ft. of torque. Hybrid MAX Grand Highlanders have a six-speed automatic and full-time all-wheel drive.
The TX lineup also offers three powertrain options. The TX 350 uses the same 2.4-liter turbocharged four-cylinder, tuned here for 275 horsepower and 317 lb-ft. of torque. The TX 500h pairs that same engine with a hybrid system for 366 total system horsepower, using Lexus's DIRECT4 all-wheel drive and a six-speed automatic. The range-topping TX 550h+ swaps in a 3.5-liter V6 plug-in hybrid for 404 total system horsepower, with a manufacturer-estimated 33 miles of electric-only range.
Taking a closer look, Toyota's Hybrid MAX engine, priced below the TX 500h, produces 362 horsepower and 400 lb-ft. of torque, landing within four horsepower of the Lexus. If raw hybrid output is the priority, the Grand Highlander offers that for thousands less. Hybrid models of the 2026 Lexus TX start in the $72,000 neighborhood, whereas Hybrid MAX models of the Grand Highlander will start between $57,000 and $58,000.
Fuel economy is the biggest surprise
Toyota wins on efficiency, gas or hybrid
The Grand Highlander's base gas engine returns an EPA-rated 21 in the city, 28 on the highway, and 24 combined on regular gasoline. As noted a moment ago, the TX 350 uses the same 2.4-liter engine, but Lexus tunes it to require premium, an added cost at the pump. And it returns slightly less at 21 in the city, 27 on the highway, and 23 combined.
The EPA estimates the Grand Highlander will cost $2,600 a year to fuel, against $3,350 for the TX 350, a $750 difference.
Hybrid trims between the two SUVs are similar. For example, the Grand Highlander Hybrid, in its lightest FWD XLE configuration, is EPA-rated at 37 in the city, 34 on the highway, and 36 combined. The TX 500h, Lexus's hybrid option, is rated at 27 in the city, 28 on the highway, and 27 combined.
The cheapest hybrid Toyota sells beats every hybrid Lexus sells in this comparison on fuel economy, including the flagship plug-in. The explanation here could be that Toyota is tuning its hybrid powertrains for efficiency, while Lexus is tuning its hybrids for performance.
Cargo and passenger space is identical
Lexus does not offer seating for eight, however
The Grand Highlander has an 116.1-inch wheelbase and a maximum cargo capacity of 97.5 cubic feet with the seats folded. The TX has a 116.2-inch wheelbase and a maximum cargo capacity of 97 cubic feet. In other words, both SUVs are nearly the same when it comes to the wheelbase and max cargo capacity.
Third-row legroom is 33.5 inches in both SUVs. Second-row legroom is 39.5 inches in both. Front headroom, second-row headroom, third-row headroom: all within a few tenths of an inch of each other across the two vehicles.
The one real difference here is passenger count. The Grand Highlander offers seating for seven or eight, with an available 60/40 fold-down bench in the second row. The TX tops out at seven passengers and never offers a bench seat.
Meanwhile, the TX's standard touchscreen measures 14 inches, versus 12.3 inches on the Grand Highlander. The same holds for the audio systems, with the Grand Highlander having an available 11-speaker JBL system, while the TX offers a 21-speaker Mark Levinson setup, nearly double the speaker count.
Semi-aniline leather is available on the TX Luxury trim, an arguably more premium material than the leather-trimmed seats at the top of the Grand Highlander lineup.
The TX also gets hardware the Grand Highlander does not offer at any price. For example, the Lexus Adaptive Variable Suspension adjusts damping in real time on select trims, while the F Sport Performance adds a Dynamic Rear Steering system for tighter low-speed turns and improved highway stability.
Advanced Park with Remote Park handles parallel and perpendicular parking on its own for the TX, a feature missing from the Grand Highlander's option sheet.
Starting MSRP considerations and warranty info
Buyers who want the upper end of the luxury experience will likely be happier with the TX, but for most, the Grand Highlander is the better option. Not only will it be less expensive to buy, but it will also be less expensive to gas up on a regular basis. It also has the option for eight seats for larger families who need the space.
Selling points of the Lexus TX include the adaptive suspension, rear-wheel steering, self-parking features, and a Mark Levinson sound system. Again, whether those upgrades are worth the extra $14,600 in starting MSRP is another story.
The 2026 Toyota Grand Highlander has a three-year, 36,000-mile bumper-to-bumper warranty, a five-year, 60,000-mile powertrain warranty, and five years of corrosion protection (unlimited mileage). The hybrid battery carries a 10-year, 150,000-mile warranty.
The 2026 Lexus TX has a four-year, 50,000-mile bumper-to-bumper warranty, a six-year, 70,000-mile powertrain warranty, and six years (unlimited mileage) of corrosion protection. The hybrid battery gets the same 10-year, 150,000-mile coverage as the Grand Highlander.
