Was just watching review on MotorWeek, they said the 2015 is getting 28MPG highway. Is this real life?

Motorweek drivers have a lead foot. I think they averaged 23 on the last model.

You have to remember they went to the FA series motor with Direct Injection.

My mom averages 31mpg mixed in her 2014 FXT with the FA20

They also went with a 6 speed transmission vs the 5 speed in the previous generation. You have a whole other gear and are running at lower RPM's on the highway.

I haven't researched much on Subies past 2007, but back in the day the Subaru 5 speed and 6 speed would cruise close to the same RPM. I think we were getting 200rpm more in my 6 speed.

It's a sports car and it meant to burn more gas than an economy car.

Yes, USDM WRX 5 speeds have a slightly taller 5th gear than the STI's 6th. Legacys have even taller gears in the GT and Spec.B.

It's a sporty car but far from a sports car.

Sure. Highway at a reasonable speed, no turbo-boost, no hills, no head-winds, and no real traffic.

Remember the cvt transmission gives better gas mileage than a manual trans.

The EJ motor being terribly inefficient plays a larger role than the transmission. The new WRX is most likely getting good gas mileage from the engine not anything to do with a transmission. That's why my BRZ gets 33hwy and 28 mixed.

I wish my forester had the FA motor.

I do agree the transmission plays a huge role, but the new WRX gets great gas mileage and the STi retains the **** EJ and the gas mileage that goes along with it.

I highly doubt it. I mean it depends on the way you drive. I have a C63 AMG Benz and I can get 24mpg on the highway if i'm babying it.

I just got my 2015 WRX ( W/CVT )
on my drive home from the dealership (50 miles of driving )
I left the car in " I " intelligent mode (CVT MODE )
and I got 30 MPGs average for my drive no joke ...

I can only imagine after a proper engine break in maybe I'll
see as high as 32-34 Highway MPG.

but my driving condition was mainly 65mph with burst up to " XXX" mph
speeds but mostly 65-70mph during engine break in period.

Motor Trend saw a whopping 1mpg improvement with their 2015 WRX tester 6MT vs their previous 2013 WRX tester.

so the trip computer is a lie ?
But overall I got a feeling in normal everyday driving I'll average
26-28mpg unless I drive spirited fashion.

That's what I wanted to hear. I want to buy a Premium CVT and I'm hoping the mileage won't be too bad in b2b Chicago traffic if I leave it in "I".

How does it feel in "I"? Does it go if you floor it or do you have to switch to S/S#?

- For the next week it'll be easy commute in " I " mode ...
but next sunday it'll be in " Sport # " when I follow some
STI / S2K / Z4 n etc around the twisty bay area back roads.

- In " I " mode the boost won't come on till pass 2,000 in revs,
but rather than being kicked in the back its more like a steady surge
of power (very linear ).

-I have yet to use Sport or Sport # , but from what I've read/heard..
In Sport the car will boost you up to 60mph if you use more than 30%
acceleration on the gas pedal ( there is a screen showing how much Acceleration your currently using).

-Sport # ... should be reserved for backroads only IMO since you'll hit
triple digits before you know it.

The trip computer MPG is going to be generous. To get an accurate idea, you have to calculate it yourself. Typically the computer readout is 2-3mpg off.

Dunno, the one in my Mazda 3 is dead accurate, tested against my manually-recorded data over a period of 5 years. I'm pretty sure it varies from one manufacturer/model to another.

Well, if the trip computer for the '15 WRX is anything like my Impreza or WRX, thill is correct in his statement. My WRX is a bit more accurate than my Impreza though.
