General Motors Corp. appoints David Piper to vice president and general manager of GM Powertrain Europe, to replace Greg Deveson, who has left the company.

Rita Forst will succeed Piper as executive director of product engineering in Torino, Italy. Piper will report to Tom Stephens, group vice president-GM Powertrain, and GM Europe Chairman Fritz Henderson.

The appointments are effective Aug. 1.

"David's broad experience in product engineering, as well as his experience within Allison Transmission make him ideally suited for this assignment," says Stephens.

Piper joined GM in 1976. In 2001, he was appointed general director of product engineering for the powertrain joint venture between GM and Fiat Auto Spa, based in Torino. In 2003, Piper was named vice president-product engineering.

Forst joined GM's Germany-based Adam Opel AG unit in 1977. She has held positions in product engineering, chassis, and manufacturing engineering with Opel and served as director of engineering for the GM-Fiat Powertrain JV.

Daniel Nicholson will succeed Forst as director of product engineering in Germany. Nicholson has been chief engineer of the small-block engine program at GM Powertrain. His replacement will be announced later.
