Drivability refers to the overall condition and performance of a vehicle's engine, transmission, steering, brakes, suspension system, and other components that affect how well it runs and handles on the road. It is an important factor in determining whether or not a car is safe and reliable for driving. A vehicle with good drivability will start easily, accelerate smoothly, handle well, stop quickly, and provide a comfortable ride. Poor drivability can result from issues such as engine problems, transmission trouble, faulty ignition system, worn-out brakes or suspension components, or alignment problems.
