Lexus is known for making luxury vehicles designed according to its defining philosophy: "the pursuit of perfection". In the 2023 Auto Trader New Car Awards, it was voted 'Most Reliable Brand' for the fourth time, maintaining its status as a top manufacturer in the UK.

With several cameos in TV shows (notably Breaking Bad, Silent Witness and Modern Family) and mentions in hip-hop songs (Ignition by R. Kelly and Jay-Z's Somewhere in America), this is a brand deeply ingrained in pop culture.

Lexus has also made waves in the world of motorsport, becoming the first manufacturer to enter a production hybrid car - the Rx 400h - in the Nurburgring 24-hour race.
