Chevrolet took the challenge of making a compact car with a quiet interior seriously when they were developing the 2011 Chevrolet Cruze. The result is a car with the quiet and refinement of a larger vehicle, but the value and efficiency of a compact.
To meet their objectives for the U.S. market, engineers developed more than 30 acoustic treatments that mute unwanted engine, road, and wind noise. Here are 10 of the most significant features:
500 inches of structural adhesive reduce structural noise and increase body strength
Seven pints of liquid sound deadener on the cabin floor mute road and friction noise, and weigh 30 percent less than conventional sound-deadening materials
A five-millimeter, acoustic-laminated windshield quiets wind noise
Triple seals for all four doors block wind and road noise
30 “Snickers bars” of expandable, sound-blocking baffles in the roofline and window frames quiet noise transmitted around the door openings
The 26- x 50-inch hood liner features acoustic materials that mute engine noise
Two sound-absorbing mats on both sides of the front-of-dash panel isolate engine noise, and save three kilograms of weight by using lightweight materials
A 15-millimeter-thick mat in the spare-tire well absorbs road noise
Four wheel-well liners, backed with textile material, block tire noise
A five-layer headliner muffles cabin noise
