This puppy is loud. Fairly unrefined engine noise is always constant, made especially evident when running the continuously-variable transmission through its paces. Hammer the throttle and the CVT pulls the engine up past 6,000 rpm to redline where it hovers for some time, which when combined with a relative dearth of power, gets loud and annoying. Road noise is also intrusive, as poor sound insulation forces Caliber occupants to hear everything on the roadway. Wind noise may be a problem, though it’s too hard to tell with all of the racket in the cabin. Finally, the collection of plastics clunk and thunk over bumps.
