General Motors’ desire to reduce weight in vehicles not only pays off in individual vehicle performance and fuel economy, but it has a substantial effect on pollution, too.
According to Automotive News, GM’s efforts to design and engineer lighter vehicles has resulted in a lineup that produces 137,000 fewer metric tons of carbon dioxide than before.
“That’s the equivalent of almost 30,000 passenger vehicles driven for a year, or the equivalent of 326 million miles driven by an average vehicle,” said Charlie Klein, executive director of GM’s global CO2 strategy, mass and aerodynamics. “That’s the benefit of those types of savings.”
In total thus far, seven GM vehicles has led to a combined weight reduction of 2,400 pounds. Those seven vehicles — the Chevrolet Malibu, Camaro, Volt and Cruze, the GMC Acadia, the Buick LaCrosse and the Cadillac XT5, are estimated to save 50 million gallons of gasoline per year.
