Lexus has expanded its SUV line with the all-new TX, a three-row model that shares its dimensions and many mechanical bits with the new Toyota Grand Highlander, although the Lexus is more plush and luxurious. The TX takes over for the previous RX L, which didn’t offer a truly functional third row. This new Lexus benefits from a boxy shape and added length over the latest RX, enabling spacious accommodations for all three rows, along with tremendous cargo-toting abilities when the third row is folded down.
