Fisker replaces CEO LaSorda with former Volt boss Posawatz

Fisker Automotive has replaced CEO Tom LaSorda with former Chevrolet Volt boss Tony Posawatz.

LaSorda, 58, a former chief executive of Chrysler, will step down effective immediately, though he will continue to be available to the maker of plug-in hybrids as an adviser, company executives said today in a conference call. LaSorda was named CEO on Feb. 28 after joining as vice chairman in December 2011.

Posawatz, 52, left General Motors last month. He had been vehicle line director for the Volt since 2006 and was the public face of Chevy's plug-in hybrid.
