Yes, i turned on the Sport mode and wow the car was more responsive and more power. Anyone has info on the MPG difference btw ECO, Normal and Sport modes?

Sport mode does not give more power.

Sport mode delivers power faster, less latency after driver inputs.

The power delivered by the system is always the same.

I pressed the Sport button. Now what?
Initiating Sport Mode in your Toyota vehicle manipulates certain elements of the transmission lockup and shifting as well as the throttle response and Electronic Power Steering assist. More specifically, you’ll feel the gas pedal is easier to press down and acceleration is much quicker, since the gears shift up faster than when driving in normal mode. Sport Mode is designed for improved handling and lateral stability, which makes for a much sportier driving experience and a more performance-oriented feel. It’s worth noting that, while in Sport Mode, you may notice a reduction in fuel efficiency.


Still didn't answer your question..
"improved Handling and lateral stability"
How?? Software??
Probably, by using the awd system


ECO Mode

• Gas pedal less responsive--helps prevent jack rabbit starts and unnecessarily quick acceleration when resuming cruise control
• Softer shifts
• Transmission shifts into higher gears sooner to maintain lower engine RPM
• Reduces air conditioner compressor draw on electrical system

Sport Mode

• Essentially the opposite of ECO Mode
• Transmission holds gears longer to keep engine at higher RPMs
• Firmer shifts
• Gas pedal very responsive to actuation

I would not say that in sport, the gas pedal is "easier" to press...its more responsive.
