Since getting the GS 3 months ago, just once or twice a day in Normal mode. Now that I've discovered that Sport mode unleashes quite a different animal, I will have to up my average considerably over the next couple of weeks...!

At WOT the engine performance is the same regardless of which Drive Mode you happen to be in.

I think the reason for this (in normal driving) is related to the new motor we get in the 2016+ cars. They have the ability to switch between the traditional Otto cycle and the Atkinson cycle (like a Prius) whereas the older GS models don't. I'd wager a bet that in Eco mode when driving as fit for that mode, we're running the Atkinson cycle most of the time whereas I'd bet in Sport mode, we're only running in Otto.
If you ease into full throttle, Sport mode would definitely be quicker as the throttle response at the top of the pedal is significantly enhanced. If you floored it hard in Eco vs Sport, I'd bet there's a slight difference as all of the valvetrain & transmission timing as well as Otto vs Atkinson modes need to changeover whereas in Sport mode, the vehicle is already ready to go.

Supposedly but I really don't think this is 100% accurate. It feels like different methods of achieving nearly the same thing. At freeway speeds, flooring it to the kickdown switch in Eco and Sport S+ is very different. I agree with chinee. Sport mode, especially S+ is really something else. It is a monster at highway speeds in S+ and really just wants to go.
For the record, this is my final post in this thread. I'm not here to argue with you or go back and forth on what you think is correct. These are my thoughts and views based on my experience with my GS. We've got very different vehicles so your mileage may vary.
I do several WOT's within a span of minutes, so if I total them up in a day, it would be difficult to justify still calling it "several times a day". Definitely need to go out for a few pulls tonight given we are expecting some snow.

Your comments beg this question, which I hope you will answer: What engine performance parameters (e.g. timing, fuel, etc.) are different at WOT in different Drive Modes?
In what way is your vehicle different, which would be applicable to the topic?
I go WOT in my RC, my electric skateboard, I even WOT my bicycle too.
Anyone know if these cars are limiting the HP in modes other than Sport or +? I feel like I'm not at 300 HP unless I'm in Sport+. The WOT pull isn't the same, especially at high speeds.

The performance of your car may 'feel' different when in different Drive Modes at WOT, but both the engine and the transmission [upshift] parameters (at WOT) are the same (at peak performance) whether you are in Eco or Sport+, or any other Drive Mode between Eco and Sport+.

Bob, while your car may 'feel' different when in Manual mode, the engine and the transmission parameters are the same, except in Manual mode 'you' decide when to shift instead of the transmission logic, with one exception - the transmission will upshift automatically at redline whether you are in Manual mode or in Drive.

If there were additional throttle and transmission response changes at WOT in Sport or Sport S+ Drive Modes Lexus would advertise that as it would be a great selling point. But that's not the case...
The Drive Modes do not enhance acceleration at WOT. That is why there is only one published 0-60 mph (or 0-100 mph) time rather than 3 or 4 - or one for each Drive Mode. What Lexus does is adjust the throttle input sensitivity that lets you [for example] move the pedal 25% in Eco Mode, which translates to [say] a 15% throttle opening, whereas that same 25% pedal movement in Sport or Sport+ Mode might translate to maybe twice the throttle opening providing a stronger accelerator response, but 'only' at partial throttle conditions. At Wide-Open-Throttle the computer immediately provides peak performance regardless of which Drive Mode you are in.
just switched from takeda back to stock to do some work at the dealership and man, intake makes a big difference. temporarily keeping stock intake on to see if it impacts my mileage at all
