Q50 Hybrid sport vs non-sport differences, fuel economy

[Celidor]

I am curious if anyone knows what the main difference between the sport and regular versions of the Q50 hybrid are. I have not been able to find out any information on the specifics.

If you look at the fuel economy estimates between sport and non-sport there is a large difference both in city and highway.

I know that the sport model comes with different suspension and paddle shifters. But the power output is the same. And I didn't think there was much else different.

Are the gears in the transmission set differently?

There is a very large difference in fuel numbers! (Picture from fueleconomy.gov included.) The AWD sport model says it burns almost 1 whole litre more per 100km on the highway (4 mpg less).

Also, is there a big improvement in acceleration to warrant such vastly different fuel economy numbers?

Looking at automobile-catalog for the 2014 year it says all 4 models have the same setup for gears. But I also found that the weight of the sport models was a lot more than the non-sport. The non-sport also had thinner tires and smaller wheels.

Q50 Hybrid RWD - - - - - - 3913 lbs - 225/55 R17
Q50 Hybrid Sport RWD - 3973 lbs - 245/40 R19
Q50 Hybrid AWD - - - - - - 4085 lbs - 225/55 R17
Q50 Hybrid Sport AWD - 4149 lbs - 245/40 R19

So I suppose the sport models' larger wheels and wider tires are the main reason for the extra weight and it also makes sense why they have worse fuel economy. Apparently it also means the sport models are slower in a straight line than the non sports.

Despite the large amount of torque the wider wheels don't help with acceleration since these cars are so heavy. Though you would expect the sport models to be faster than the non-sport...

It's too bad that Infiniti didn't tweak the gearing for the sport models. Lowering gears 3-6 would have made the sport models quicker than the non-sport. Keeping 7th the same for highway cruising.

I am running the 2015 Q50 S hybrid. AWD,, average MPG on motorway driving or fast open roads, drive reasonabe speed but not crazy, 33 to 34 mpg 65 to 80 mph
