2026 Lexus TX Vs. Grand Highlander Detailed Comparison

Lexus TX vs. Toyota Grand Highlander Specs & MPG

A specs comparison for the Lexus TX vs. Grand Highlander is easily the most thrilling part of this matchup. Here, we find the Lexus TX leaving its competition behind.

While both models kick off the lineup with a turbocharged 2.4-liter four-cylinder engine, the Lexus TX makes 10 more horsepower than the Grand Highlander. Plus, it makes seven more pound-feet of torque. However, the two are nearly identical in fuel economy:

• Standard Lexus TX MPG: EPA-estimated 21/27/23 MPG (City/Highway/Combined)
• Standard Grand Highlander MPG: EPA-estimated 21/28/24 MPG (City/Highway/Combined)

Both lineups offer mild-hybrid prowess, but here the Lexus TX again beats out the competition. The Lexus TX mild hybrid 500h models use a 2.4-liter in-line four-cylinder engine and battery system to make 366 horsepower and offer an EPA-estimated 27/28/27 MPG (City/Highway/Combined). The Grand Highlander Hybrid uses a 2.5-liter four-cylinder engine and battery system to make just 245 horsepower and offers an EPA-estimated 36/32/34 (City/Highway/Combined).

This is where the similarities in the models' engineering take very different turns. The Grand Highlander gets a Hybrid MAX engine in select models. It uses mild-hybrid power, as well, offering a boost to 362 horsepower and a fuel-efficient EPA-estimated 26/27/27 MPG (City/Highway/Combined).

Meanwhile, the Lexus TX benefits from a plug-in hybrid setup that makes 404 horsepower, gets an EPA-estimated 79 MPGe (Combined), and can travel up to 33 miles using only power from its electric battery. The Grand Highlander simply doesn't offer the engineering to compete.

Lexus TX vs. Grand Highlander Interior Features & Cargo Space

Inside our comparison of the Lexus seven-seater SUV and Grand Highlander SUV, we find even more similar dimensions.

However, among their foremost differences is that the standard Lexus TX seats seven passengers in its standard configuration, with six seats available in sportier models. The Grand Highlander offers seating for eight passengers in its standard configuration with seven-seater options available.

The reason for this is that the Lexus TX prioritizes passenger experience with more luxury options and comfortable seating as opposed to trying to fit as many seats as possible. The Grand Highlander, on the other hand, keeps utility at the forefront, forgoing luxuries on most models in its lineup.

To see how the interior appointments and technologies compare, see a brief overview in our chart above. Clearly, the Lexus TX provides a more comfortable environment with standard ambient lighting, heated elements, wireless charging, and a 14-inch touchscreen. The Grand Highlander will require a higher-tier trim to unlock just a few of these options, but a 14-inch touchscreen won't be among them at all.

As far as cargo space goes, the Lexus TX and Toyota Grand Highlander have nearly identical cargo space measurements. The Lexus TX offers 20.2 cubic feet behind the third row; the Grand Highlander offers 20.6 cubic feet. Both offer more than 57 cubic feet with the second row folded and 97 or more cubic feet in total.
