The GS sedan expresses simplicity, yet the car is thoroughly sculpted throughout its length. The design is perhaps a little predictable, yet the combination of this sleek shape and careful work to reduce aerodynamic turbulence beneath the car has produced a remarkably low 0.27 coefficient of aerodynamic drag, and this promotes a quieter interior and fuel efficiency.

The GS has high-intensity-discharge headlights with an available system that automatically compensates headlight aim for different passenger loads. The power-adjustable mirrors have de-fogging heat elements and tilt down when the car is in reverse. The variable intermittent windshield wipers actuate automatically when raindrops are sensed. Fast-acting LEDs are used in the rear brake lights. Big 18-inch wheels are available.
