It's fair AFAIK, both are running in charge sustaining mode. The Fusion gets worse highway mileage because it's a fullsize car, not a compact, but it should also get worse city mileage. The problem with the Volt is that running everything through to a generator, then converting that back to mechanical power via the motor reduces efficiency by ~15%-20%, and the single speed trans for he electric motor hurts a bit too (~5+%). If they sent mechanical power directly from the engine to the wheels in charge sustaining mode they would do a lot better than the Fusion hybrid and be very close to a Prius.
