One of the big criticisms of the Fisker Karma is that the heavy beast isn't exactly efficient. A curb weight of 5,300 pounds is one reason why the EPA says, when running on premium gas, the Karma gets just 20 miles per gallon combined (and 20 city/21 hwy). When you throw electricity into the mix, the Karma is rated at 54 MPGe combined.
All other plug-in hybrids on the US market have better MPGe ratings – the 2013 Toyota Prius Plug-In gets 95 MPGe, the 2013 Chevrolet Volt gets 98 MPGe, the Ford plug ins – the Fusion Energi and C-Max Energi – both get 100 MPGe and the 2014 Honda Accord Plug-In Hybrid gets 115 MPGe,
Still, there is the official test rating and then there's real life, and it turns out that Karma drivers aren't big fans of pumping gas. Henrik Fisker recently told AutoblogGreen that the real-world mpg rating (that is, the miles the car moves based on gallons of gasoline put in, not counting electricity, so not an MPGe amount) is in the triple digits. He said:
We'll post our full Q&A with Henrik tomorrow. Stay tuned.
You can say what you want about how the Europeans or the EPA measures fuel economy, but we have the facts, the facts of how Fisker Karma owners drive the car. The average is 150 miles a gallon. That is a fact. And we have customers who drive 3,000 to 4,000 miles before they fill up.
