Chevrolet continues to make safety a priority as it champions the use of compressed natural gas (CNG) with the 2015 Bi-fuel Chevy Impala. The sedan’s unique CNG tank is rigorously tested to ensure its proper function and passengers’ safety in extreme situations–like those involving fires and bullets.

2015 Bi-Fuel Chevy Impala

The 2015 Bi-Fuel Chevy Impala won’t look much different than this regular 2015 model.

The tank’s valve and connection are protected by a piece of cast aluminum, while the sides of the tank receive extra insulation from sheet metal plates serving as a buffer from rolling objects in the trunk or rear seats.

When testing the trunk-mounted tank’s ability to withstand various pressures, engineers surpassed industry regulations and federal requirements.

The standard Bonfire Test requires the CNG tank to be tested by placing an 800-degree Fahrenheit fire just four inches below the tank. General Motors’ engineers turned up the heat, adding fires near the trunk, back seat, and vehicle’s underbody as well.

Another test requires the tank to be shot with an armor-piercing 7.62 mm bullet. During the Penetration Test, when a bullet pierces the tank, it should not be able to pass through the tank and come out the other side; and the tank should not rupture.

“We designed this system for those ‘what if’ situations,” said Nichole Kraatz, chief engineer for the Impala. ”The customer shouldn’t even know it’s there. They shouldn’t even think about it. CNG should just be another fuel they use to power their vehicle.”

The Bi-fuel Impala was also subjected to front barrier and side and rear impact crash tests to ensure the vehicle’s overall safety.

The alternate fuel sedan is a 2015 Green Car of the Year® finalist and is now available to order. Contact us here at Lang Chevrolet for more information.
