The 2018 Lexus RX L models now have the option of a third row. The new models were unveiled at the Los Angeles Auto Show. Lexus extended the body length by 4.3 inches at the rear and used a steeper tailgate window angle than on the two-row models.

The standard seven-seat version uses a 40/20/40 split bench-type second row seat. A lever that slides and folds the second seat forward helps with easier access to the third row. The positioning of the second row is slightly higher than the third row, creating more foot room for rear passengers.

The 2018 Lexus RX 350L has a 3.5-liter V6 with a D-4S fuel injection system, which combines direct and port fuel injection systems. The engine delivers 290 horsepower (hp) and 263 pound-feet (lb.-ft.) of torque with an eight-speed automatic transmission. As on the two-row RX 350, the RX 350L is available with front-wheel drive or available Dynamic Torque Control All Wheel Drive.

The 2018 Lexus RX 450hL uses the Lexus Hybrid Drive system that pairs the D4-S injection 3.5-liter V6 gasoline engine with two high-torque electric drive motor-generators. In the RX 450hL, the Drive Mode Select system adds a fourth mode, EV, which enables the vehicle to drive under electric power at lower speeds for short distances.

In the new RX L models, side curtain airbags cover all three rows. The standard Lexus Safety System+ includes pre-collision system with pedestrian detection, lane keep assist, intelligent high beams and all-speed dynamic radar cruise control. Blind spot monitor with intuitive parking assist and rear cross-traffic braking are also available.

The RX 350L will be available in dealerships later this year.
