The verdict: Lexus updated its entry-level sports sedan for 2021, and the IS 300 and IS 350 get more muscular styling as well as an updated multimedia system that should be easier to use than the outgoing version. Also in the easy column are the sedan’s lower Latch anchors, which are exposed for quick connection. Unfortunately, insufficient rear legroom prevented the IS from earning top grades.
Does it fit three car seats? No.
Take a look at how the Latch system and each car seat scored below in our Car Seat Check of the 2021 Lexus IS 350.
