At the top of the pile, the GS-6S, or Sport, gets a handful of enhancements to justify its name. Firstly, it gets the Performance Package as standard, which adds an extra 100 lb-ft of torque to the motors and drops the 0 to 60 mph sprint down to 3.9 seconds. T also benefits from extra grip thanks to low-profile tires on 22-inch alloy wheels housing cross-drilled brake discs. Visually, it gets black window surrounds, while inside, the trim is carbon fiber by default. The specification is otherwise mirrored with the Luxury trim.
