The all-new 2020 Lexus LX 600 is the most sophisticated — and capable — of SUVs, its 3.5-liter twin-turbo charged V6 complemented by high-end interior tech like dual high-definition touchscreens and available 25-speaker Mark Levinson Surround Sound. This fourth-gen LX looks as good as it performs, its five grade options include the first ever F Sport and Ultra Luxury.
