Lexus TX vs. Toyota Grand Highlander: A spec-by-spec comparison

Avatar photo

With the reveal of the 2024 Lexus TX, it’s natural for people to draw some comparisons between it and the Toyota variant since they are built on the same GA-K platform. Therefore, even though we only have a limited spec release for TX so far, we figured it would be worth doing a quick Lexus TX vs. Toyota Grand Highlander comparo, so you can see where some of the differences are.

While the sizes are generally the same, there are a couple big differences between the two vehicles. So, let’s dig in.

Powertrains & fuel economy

Perhaps the biggest difference in the Lexus TX vs. Toyota Grand Highlander comparison is going to be powertrains. While they share the base gas engine, and one of the hybrid powertrains, the TX gets a plug-in hybrid electric (PHEV) variant, while the Grand Highlander does not.

This could be a huge selling point for carpoolers and commuters alike, as the TX will get about 33 miles of all electric range with a combined fuel economy rating of 30 MPG. That’s in addition to a huge power boost a 406 horsepower.


Another big difference will be wheels. The base wheels on the Grand Highlander will be 18-inches, whereas TX starts at 20. And the TX goes up to 22-inches while the Grand Highlander stops at 20s.

A tiny difference in size

Both vehicles have the same wheelbase, but other than that several of the measurments are just a little bit different. What we find really interesting is that though the TX is about 2 inches longer, it has less overall cargo volume by a tiny bit. Since we don’t have legroom and headroom specs yet for TX, it’s hard to say where that extra length went, but we’re guessing it went to passenger comfort not cargo capacity.

Regardless, according to photos we saw during the press reveal, the TX will also be able to hold seven carry-on bags with the rear seats up.

The bottom line

Looking at the Lexus TX vs. Toyota Grand Highlander specifications, you can definitely see where Lexus tried the most to stand out – in visual and powertrain arenas. We’ll be curious to drive the TX, but we anticipate it will be as much of a home run as the Grand Highlander was – if you can get over the grille.

    Lexus ts front grille and interior center console are failures, while Hanlan’s design is better

    The Lexus TX front grill looks so aweful. Did Lexus outsource the design job to a toddler? or Toyota is out of money when designing the front grill. Big let down.
