2011 Chevrolet Volt Long Term Road Test


2011 Chevrolet Volt: Aerodynamic Side Effect

May 02, 2011

Volt on hill.jpg I often drive with the windows down. I like the fresh air and in the case of our Chevrolet Volt, you can bypass the AC as a way to conserve battery life. But sometimes, the Volt makes this simple task hard to do. There is a great deal of wind buffeting that occurs at speeds of 60 mph and above. It is even more pronounced if only one widow is open. The buffeting is loud and creates a vibrating noise that hurts your ears. Cracking the rear windows helps a bit, but sometimes you don’t want that much wind and noise coming into the car. I tried to record the buffeting in a short video after the jump.

The Volt is an extremely aerodynamic vehicle. According to General Motors, outside of the EV1, the Volt has the lowest drag coefficient (0.28) of any vehicle the company has built so far. The aero design helped the Volt's designers realize a 7-mile improvement to the electric range. But it seems as though this ideal pocket of airflow that the Volt creates also has a side effect: This irritating wind buffeting.

Take a look at this video for a behind the scenes look at the Volt's aerodynamics.



If you're one of Volt owners that reads this blog, I'd be curious to know: Have you noticed the buffeting?
