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. All-wheel drive is standard. 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.
