When Lexus dealerships begged the company to build a three-row crossover to slot above the RX and below the body-on-frame GX, they got the RX L. Essentially a slightly elongated RX with a cramped third row, the Lexus RX L was not the critical success Lexus dealers hoped for. The company's next attempt should be more promising. Way back in 2014, Lexus was spotted filing a trademark for the name "TX." Though it has yet to materialize, the TX is rumored to be the first dedicated Lexus three-row crossover.

Speaking with Automotive News, insider sources confirmed the TX will be based on another rumored model, the Toyota Grand Highlander. The Grand Highlander name was trademarked by Toyota, and will reportedly slot between the Highlander and Sequoia. Both the Toyota and Lexus are slated for production at Toyota's plant in Indiana.

The TX and Grand Highlander will reportedly arrive in mid-2023, meaning we could see them revealed later this year. Toyota will hold its annual HQ Confidential event - where it reveals new Toyota and Lexus products - from the end of May through the beginning of June. This would be the perfect opportunity to reveal or tease something. The insider source says the Grand Highlander will arrive first, followed by the TX around six months later.

Toyota has typically declined to comment on either product, though the Indiana plant is currently undergoing an $803 million upgrade to build new models. The Japanese automaker has confirmed that the two new vehicles built in Indiana will get a semi-autonomous driving system with hands-free capability. This is likely referencing Toyota/Lexus Teammate, which is currently available on the Mirai and LS 500h. Toyota also confirmed both models will seat up to eight passengers, meaning second-row captain's chairs will likely be optional.

Judging by the trademarks for the names "TX 350" and "TX 500h," we know the TX will be offered in gasoline and hybrid forms. We assume the TX 350 will get the same 2.4-liter turbocharged four-cylinder found in the NX 350, while the TX 500h could be the first Lexus to use the turbocharged engine in combination with electric motors, as the naturally aspirated setup in the NX 350h wouldn't be potent enough to support the larger TX. As for the Grand Highlander, we imagine it will arrive with similar powertrain options producing slightly less power. More info will follow as soon as we have it.
