2024 Lexus LC500

The 2024 Lexus LC500 is a luxury grand tourer, celebrated for its striking design, refined interior, and engaging driving experience. Available as a coupe or convertible, it primarily appeals to drivers seeking a blend of style, comfort, and performance. While it’s praised for its smooth ride, luxurious appointments, and reliable Lexus build quality, some common dislikes include its limited rear seat space (in the coupe), smaller trunk space, and infotainment system interface. The LC500 is powered by a naturally aspirated 5.0-liter V8 engine producing 471 horsepower and 398 lb-ft of torque, paired with a 10-speed automatic transmission. There is also a hybrid option with a 3.5L V6. Because this information is not as commonly available, I will only be including information about the standard gasoline version.
