Ford Fiesta Proves to Be a Quiet Ride

American manufacturer Ford found yet another thing to praise about, and announced its 2011 Fiesta meets the same noise, vibration and harshness (NVH) standards as larger Ford cars, therefore delivering "class-leading small car quietness."

According to Ford, the Fiesta, which arrives in Ford showrooms this summer, has interior noise levels lower than the Honda Fit and the Toyota Yaris in the 80 mph wind tunnel testing.

“A buyer of a larger car expects it to be quiet,” said Steve Pintar, Fiesta chief nameplate engineer. “For a Fiesta driver, the quiet cabin will be a welcome surprise, allowing them to better enjoy a conversation with a friend or their favorite road tunes.”

Tests showed that in 80 mph wind tunnel testing on the highway, the inside of a Fiesta records 25.4 sones compared to 27.6 sones for the Honda Fit and 26.2 for the Toyota Yaris. Moreover, the Fiesta also is quieter than the larger Toyota Corolla, which measures 30.3 sones.

“A smaller car can pose challenges for noise and vibration control. You have smaller spaces to work with, and there are always cost and material concerns to keep the car affordable,” Pintar said. “Small-car buyers don’t need to compromise a quiet cabin to enjoy top fuel economy.”

Fiesta interior noise control package enhancements include:

• Acoustic-laminated windshield, reducing wind noise
  
• Wind tunnel-optimized side-view mirrors, reducing wind noise
  
• Stiffened door modules, reducing the potential for rattles
  
• Rear-mounted roof antenna for less wind noise and improved aerodynamics
  
• Wind noise-optimized grille
  
• Additional sound-absorbent material throughout the cabin for a quiet interior
  
• Revised door seals for reduced wind noise
