Feature Showdown
Both come with modern infotainment systems. Apple CarPlay and Android Auto are standard across both.
The BMW X5 counters with panoramic roof, Harman Kardon audio and ambient lighting that the Lexus GX does not offer. Which feature set matters more depends on your daily routine and priorities.
Drivetrain
