GM is showing off the high heat tests that it is putting the Volt through in Arizona. The heat testing is being conducted at the GM Desert Proving Grounds in Arizona. This is some key testing for the Volt to see how well the vehicle operates in hot environment.
Some batteries and EVs lose significant amounts of run time when used in hot environment. GM should test in Texas where we have lots of heat and extreme humidity as well. I know the battery on my iPhone lasts longer in Las Vegas than it does here in Texas, which I can only attribute to the humidity at home.
The Volt is baked in the sun for several hours with the inside of the car reaching 175 degrees. The vehicle is then driven around the test track to listen for squeaks and other issues with the car. Engineers say the Volt is doing well so far.
