Toyota focused on the texture and feel of the front seat and dashboard for the North American market. The seats themselves have increased lumbar and bolster support — and I really felt the difference behind the wheel. The Corolla driver seat is very comfortable, which you will not take for granted during long road trips.
The interior features a mix of a shiny "piano black" and brushed metallic surfaces throughout. The piano black, which surrounds the infotainment, feels excessive and makes the interior look cheap where it doesn't need to be. Metallic brushed-chrome accents framing the infotainment system would probably be better.
When starting the engine, the first thing you notice is how quiet the cabin is. This is, of course, intentional. The floors have extra carpet insulation, and the car is made with an acoustic glass windscreen, a fender sound insulator, and an inner dash silencer pad to help keep environmental noise level down.
