DETROIT — Troubled electric car maker Fisker Automotive Inc. has laid off about three-fourths of the workers at its California headquarters as it struggles with financial and production problems.
The Anaheim, Calif.-based company confirmed the layoffs on Friday, saying it is pursuing ‘‘strategic alternatives’’ to get through financial challenges, but it reached a point where the layoffs are necessary.
‘‘The company regrets having to terminate any of its hard-working and talented people. But this was a necessary strategic step in our efforts to maximize the value of Fisker’s core assets,’’ the statement said.
Fisker, which makes the $100,000 Karma plug-in hybrid sports car, hasn’t produced any cars since last year after its battery supplier filed for bankruptcy protection. Last month, its cofounder resigned and Fisker furloughed its staff of about 220 for one week. The company at one time had about 600 workers.
The statement said Fisker met with workers on Friday to tell them this would be their last day with the company. Core workers who will be kept were told on Thursday.
