The new three-row, seven-seat crossover will be shown in RX350 guise, presumably powered by the brand's 221kW 3.5-litre naturally aspirated V6.
There will also be a RX450hL model, but this will be unveiled at a later and yet-to-be-specified date. This model will likely feature a 230kW hybrid drivetrain with a 3.5-litre V6 at its core.

A report in Mag-X earlier this year indicated the RXL will feature a lengthened area aft of the C-pillars in order to accomodate a third row of seats, but will not come with a stretched wheelbase.
All up the RXL will reportedly measure 5050mm in length, up 160mm on the five-seat model. Overall styling is expected to be pretty close to what's used on the five-seat RX, which has been in production since 2015.
We'll find out more about local availability and timing when the car is revealed at the end of the month in the city of angels.
