Push the Lexus LS 460L in hairpin turns and discover that the car can be throttle steered, often unintentionally because the accelerator is ultra-sensitive. The tail swings out easily, caught by the stability control system before it incurs damage, and because the driver usually isn’t expecting this behavior it’s discomforting. Grand, sweeping, high-speed curves better showcase the Lexus as a rewarding performance machine. Here, the feather-light steering firms up nicely and the soft suspension takes a better set. Regardless of driving style, however, the brake pedal is the LS 460’s dynamic Achilles’ heel. Feel is awful, it’s hard to modulate, and making smooth stops is almost impossible.
