Second Fisker Karma Burns – Did EV1/Volt Engineer Predict Cause?

A second Fisker Karma has been reported by Jalopnik to have caught fire and burned yesterday. The owner returned with his groceries to find the car in flames in a Woodside, California parking lot. Interestingly, he first called Fisker who advised him, wisely, to call 911. Back in May, after a Karma started a house fire in Texas, engineer John Bereisa said that the proximate cause of that fire was likely heat, the result of tight engine packaging. The ultimate cause, he suggested, was the hybrid vehicle’s weight, which Bereisa said necessitated a larger, more powerful combustion engine to power the car’s generator that charges the batteries for extended range use. Bereisa is one of the world’s experts on building electric and hybrid cars.


In May, Bereisa told Automotive News:

“That engine is shoehorned into that bay, because they had to use a larger engine, because it was too heavy a car. As a result, there’s no room for exhaust routing and heat shielding to route the heat away… [the Karma is] using the hell out of that motor-generator.”

Bereisa also noted how tightly packed the exhaust system is. In those circumstances leaking fuel, oil, or even coolant (glycol is flammable) could ignite from heat or a hot surface.
Fisker issued a statement to Jalopnik:

We have confidence in the Fisker Karma. Safety is our primary concern and our Fisker staff have been in contact with the customer and are investigating the cause. We are also employing an independent fire investigation representative to assist in the root cause analysis. A further statement will be issued once the root cause has been determined.
