GM’s contribution to innovation in its industry has clearly put it ahead of its competitors

During the past year, GM accumulated 1,643 patents, according to the Patent Board study. Patent volume is necessary, but commercialization for customer benefit is most important.

“GM is the only company to have achieved the No. 1 position 11 consecutive times in the Patent Board’s Automotive and Transportation industry ranking,” said Karl R. Wilhelm, chief executive officer of the Patent Board. “GM’s contribution to innovation in its industry has clearly put it ahead of its competitors.”

GM has been granted more than two dozen patents related to the all-new eight-speed automatic transmission offered in the Chevrolet Corvette Stingray for 2015, enhancing the performance and efficiency of the 2014 North American Car of the Year.

Designed and built by GM, the new transmission delivers world-class shift times that rival the best dual-clutch designs. The transmission is more than 8 pounds (4 kg) lighter and five-percent more fuel efficient than the six-speed automatic. GM has been granted more than 24 patents related to the all-new eight-speed automatic transmission that will be offered on the new Corvette Z06.

The GM-designed 8L90 eight-speed is expected to contribute up to 5-percent greater efficiency, when compared to the previous six-speed automatic.
