I was wondering whether for freeway driving (relatively constant between 65 and 75) the sport button has any impact on fuel economy or tailpipe emissions. Anyone know?

I often commute 110 miles per day in my GT3, and I am wondering whether to turn off sport mode on the highway. At these speeds, the exhaust sound is not a factor as it is drowned out by road noise.

Thanks,

Just noise nothing else

Different engine map. MPG goes down. Slight loss of torque down low. Slightly better throttle response (just an e-gas thing)

The manual and sales materials all say that low rpm torque INCREASES with the Sport button turned on.
