When Lexus recently redesigned its RX line of SUVs, it axed the three-row L variant. That seemed like a strange decision at the time; we didn’t particularly like the L, but three-row SUVs are financially fertile ground, and leaving the aging GX and pricey LX as the only choices in its lineup didn’t strike us as wise. And now we know why: The all-new 2024 Lexus TX is coming this fall to fill the gap.Riding on the same platform as the Toyota Grand Highlander, the TX will have three variants that offer gas, hybrid and — unlike the Grand Highlander for now, at least — plug-in hybrid powertrains. The gas-only 350 and hybrid 500h will be available at launch this fall, with the PHEV 550h+ joining the lineup at an unspecified later date. Besides a base model, Premium, Luxury and F Sport Performance trims will be available, with the 500h exclusively available in F Sport Performance.
