What feature aids in maintaining vehicle control on slippery surfaces?

All-wheel drive is specifically designed to distribute power to all four wheels of a vehicle, which enhances traction on slippery surfaces such as rain, ice, or snow. This system helps to prevent wheel slippage and allows for improved handling and stability during challenging road conditions. By providing power to both the front and rear wheels, all-wheel drive enhances the vehicle's ability to grip the road, making it easier to navigate turns and maintain control.

In contrast, sport suspension primarily focuses on improving handling and performance on dry roads rather than providing traction on slippery surfaces. An enhanced stereo system contributes to entertainment and comfort within the vehicle, but it does not influence driving dynamics. Similarly, having a convertible roof relates to the body style of the vehicle and has no bearing on its performance or control on various terrains, particularly slippery surfaces.
