acdii Report post Posted December 24, 2012 Being as fed up as I am I needed to do a head to head test between the two cars. The 2013 I drove first, it has the tires set to 34 PSI, the 2010 I have no idea where the tire pressures are, haven't checked them in months. Both cars were semi warmed up from a previous trip, but rested about the same amount of time between drives. The drive was 11.5 miles each way from my house to a gas station I frequent in WI. The roads were semi snow packed, which affected the 2010 a bit more than the 2013. Temp is 23 degrees F. I drove for at least 1.5 miles before I turned the heater on to low floor/defrost. I drove very conservatively, accelerating slowly, sometimes not even making it up to 55 MPH before I have to slow down for a stop. Never going over 55 MPH. Once I reached the gas station I shut the car off and filled up, then updated the fuel log, fuelly.com and fueleconomy.com and resetting the trips on both cars before starting them back up. Return trip I drove more aggressively, like I normally drive the 2010, this time getting up to speed quicker, but still keeping the RPMs under 2500. Max speed being 60 MPH, reducing speed where the snow pack needed it, but still keeping speeds up for the majority of the return trip. Results, 2013 FFH 33.7 there34.9 return 2010 FFH 33.5 there36.4 return End results showing that the 2013, which is rated 47 combined cant match the 2010 that is rated 36 highway, 41 city, 39 combined. A more truer result would have happened had the roads been 100% cleared of snow, the Michelins on the 2010 don't like rain or snow and affect MPG by at least 2-3 MPG. However, on dry pavement I saw a huge difference between the two, the 2010 Easily staying above 40 MPG instant, the 2013 would slow down if I tried to get it into EV, and as soon as I do, and try to get it back up to speed, ICE would kick on and drop the instant back down to 20. Now if anyone in the Rockford area that has a 2013 FFH that does see 40+ consistently, please PM me so we can do a truer head to head test. So far my comparisons between what I have with me driving are showing that the new car is FAR below what should be expected of it regardless of the temperatures.
