But now he's once again involved with the Karma luxury sedan.
He's joining VL Automotive, which still plans to sell Karmas with V-8 engines in place of their original extended-range electric powertrains.

The announcement was made Friday ahead of the 2016 Detroit Auto Show, where VL will display an updated version of its creation, which is known as the Destino.
The company is also re-branding itself as VLF.
Fisker is a key shareholder of VLF and is now the third member of its executive board, along with former General Motors product czar Bob Lutz and, industrialist Glibert Villarreal.
The design of the Destino has been altered somewhat since it was first shown three years ago, but VLF still plans to use the 6.2-liter supercharged V-8 from the discontinued Chevrolet Corvette ZR-1.

It will produce the same 638 horsepower it did in the ZR-1, getting the Destino from 0 to 60 mph in 3.9 seconds, and on to a top speed of 200 mph, according to VLF.
Of course, there's no longer any emphasis on efficiency and--at an estimated $229,000--the Destino will cost about twice as much as the Karma did during its brief production run back in 2012.
Both cars will be built at a facility in Auburn Hills, Michigan. VLF also has an R&D center in Los Angeles, and claims to have seven dealers lined up.

Meanwhile, Chinese automotive supplier Wanxiang--which bought the remains of bankrupt Fisker Automotive--is still moving forward with plans to restart production of the original, plug-in Karma.
Now renamed Karma Automotive, the carmaker plans to relaunch the Karma sedan later this year, with production set to begin at a new facility in Southern California.
