The cabin is driver-focused with contoured sport seats that mold to the body for support on long drives. Higher grades add leather or leatherette trim, dual-zone automatic climate control, a 6-way power driver seat with lumbar, and heated front seats. A power sliding glass moonroof is available on select grades. Sound insulation and tighter body gaps cut road and wind noise for a quieter ride. The center console and controls feel refined, with an available heated leather steering wheel.
