Like most small cars, the Ford Focus is loud inside. Under acceleration, the engine drones, and there's plenty of road and wind roar at speed. What we didn't hear in our test car was rattles, squeaks, or excessive noise from the suspension. And, if you've popped for the optional Audiophile stereo with six-disc CD changer, there's plenty of rich sound to help drown out the engine, tire, and wind noise.
