Excellent Ride and Handling
The Excelle XT has a fun-to-drive character with high levels of steering precision and ride comfort.
The chassis incorporates the proven McPherson strut layout in front. In back, Buick has applied a new suspension system for the Excelle XT — a compound crank rear axle with a Watts link. The result is greater wheel camber stiffness and compensation in body roll, with a constant track width in jounce. It also adds enhanced lateral stability for both improved handling and greater ride comfort.
The speed-sensitive rack and pinion steering system is electrically powered to save fuel. The electric motor is mounted on the steering rack rather than at the base of the steering column to give improved driver feel when turning the steering wheel. The Excelle XT is also equipped with the dual-circuit braking system, which features three brake disc combinations.
Advanced Safety and Security
With a maximum five-star NCAP safety rating anticipated, the Excelle XT's body structure along with its restraint systems are designed to exceed crash safety standards around the world.
Its high structural integrity is reflected in its solid, on-the-road feel and the suppression of unwanted noise, vibration and harshness (NVH) inside the cabin.
