The GS 430 is powered by a 290-hp 4.3-liter V8 engine. It utilizes a close-ratio six-speed automatic transmission, one of the smallest and lightest gearboxes of its type. Active safety features include anti-lock brakes, electronic brake-force distribution, Brake Assist, and Vehicle Dynamics Integrated Management, an electronic stability control system. For 2007, the GS 430's high-technology rear-wheel-drive chassis has been improved with an optional active anti-roll, body control system.
