I've got a Toyota Hybrid Camry. City & highway mileages are both between middle 30's and very low 40's. My best highway result so fare is 41.2 mpg by the dash readout. The city mileage is 37+ for nine months out of the year. It drops in the winter by a couple miles per gallon due to having to run to keep the engine temp up for the heater in town. We haven't had any real winter weather down here since I got it to see how the traction performs.
