The Generation 6 Camaro is 28 percent stiffer and has a more rigid body structure than the 2015 model.
"The modeling abilities of computer-aided engineering are advancing at incredible rates," said Jim Karlavage, Camaro program engineering manager, in a statement. "Today, we can accurately model opportunities to add torsional strength without adding unnecessary mass. The result is a lighter, stiffer structure that benefits every aspect of the driving experience."
The lighter structure "enabled the size and mass of elements such as the wheels, tires and brakes to be scaled accordingly," GM noted.
GM is slowly revealing details about the Camaro, which will be unveiled during a public event on May 16 at Detroit's Belle Isle Park.
The automaker earlier said the 2016 Camaro is at least 200 pounds lighter than the current car, signaling improved handling, acceleration and fuel economy.
Pricing and technical specifications on the 2016 Camaro have not been released. It is expected to arrive at Chevrolet dealerships in the fall.
Edmunds says: Car shoppers are getting a clearer picture about the improvements to the 2016 Camaro.
