The redesigned 2023 RX is powered by a 2.4-liter turbocharged four-cylinder engine, which replaced the smooth V6 used in past generations. It's powerful and gets good fuel economy at 24 mpg, but lacks the old V6's silky smoothness. The RX350h is the hybrid version, which is much more sparing with fuel. The ride is comfortable whether with the standard 19-inch tires or optional 21-inch ones. Handling is sound and secure but not sporty. Fit and finish is impeccable and rear seat room is generous. Rear and side visibility are limited and the electronic door latches take some getting used to. The infotainment system's touch screen is not the most intuitive and neither is the gear selector. High end versions with a head-up display have unlabeled steering wheel buttons. For 2024, a plug-in hybrid, the 450h+, with an EPA estimated 37-mile electric range was added.
