4. Still has a Taste for Fuel

2015-Subaru-WRX-STI-05

The STI has never been a particularly efficient vehicle and the new one is no different. Even with a 2.5-liter engine, the boost is turned up to crank out 305 hp and 290 lb-ft of torque. A lot of fuel is required to generate this kind of grunt and combined with short gearing, the STI is rated at a mere 17 MPG in the city and 23 MPG on the highway. After a week of mixed driving that included plenty of spirited romps, we average 19.6 mpg.

    They should have a quiet mode where the exhaust muffler system has a solenoid that will shunt the exhaust through quiet mufflers when you want it quiet. So if you want to sneak into the neighborhood or out of the neighborhood late at night you don’t wake everybody up even if you barely press on the gas at all.
    Being loud all the time isn’t good.

    Also the MPG, why can’t it get decent MPG if you stay out of the boost by being real light with the throttle? Auto start stop would be nice with a button to disable it of course

    What if you are trying to sneak away from the police? A loud exhaust doesn’t help with that one bit

    It’s a shame that the 2.5 EJ engine is still really unreliable (many people having to get a new engine after 75,000 KM only.. most of the times it has to do with the head gaskets
