For almost three decades, the Lexus LS has epitomized luxury-car serenity and excellence. With this redesign, however, the sedan’s frustrating controls, firmer ride, and tighter interior space could turn off loyal buyers.

Shoppers who want what the LS used to deliver should consider the more satisfying Genesis G90, which we think has stolen the crown for luxury driving experience.

The turbo V6 is strong when drivers push hard on the accelerator, but it doesn’t feel powerful in everyday driving.

RECENT CAR REVIEWS

The ride is steady and controlled, but the impact from bumps is too hard. The LS lacks the plush ride owners should expect.

To its credit, the LS has improved handling and added more responsive steering.

Lexus increased the car’s exterior dimensions, but the sleek styling and lower stance have cut into its usable interior space and made it more difficult to climb into than rivals.

Cabin controls are so complicated that new owners should budget time at the dealership to configure the settings. Using the touchpad to change the audio source, for example, requires drivers to take their eyes off the road to verify their choice. It’s also too easy to put the gear selector into Neutral instead of Drive or Reverse.

The driver’s seat coddles its occupant, but the heated and cooled seats and heated steering wheel can be adjusted only through the central screen using the touchpad, a tedious and distracting process.

The LS features a robust suite of standard advanced safety features.
