This article is about the 8ar-fts engine http://australiancar.reviews/8AR-FTS-engine.php
What's interesting is what I read in the last paragraph..
The 8AR-FTS engine had a ‘Stop & Start’ function that enabled the engine to shut down while the vehicle was stationary in traffic to reduce fuel consumption. The ESTEC D-4ST system could inject fuel into one cylinder while it was stopped on its compression stroke, allowing ignition and combustion to occur simultaneously to quickly re-start the engine. As a result, the Stop & Start system for the 8AR-FTS delayed start-up until the accelerator pedal was activated, in contrast to many systems which start the engine when the brake pedal is released.
So is that why we have that awful delay when we floor it from a complete stop? Just asking, correct me if I'm wrong.

The engine stop & start feature is something entirely different. The issue with the pedal delay has been an ongoing investigation, but it looks like Lexus has addressed this issue on the new 2019 turbo RC. I am not sure if it's a software or hardware update, but I am hoping something can be done for existing 2.0T owners.

If the article is referring to the fuel-saving feature of the start-stop function, there are two ways the engine starts when it is cutoff. 1) When still in drive mode, the brake pedal is released, engine starts. 2) This is abit complicated, but bear with me. When at a stop light, depress the brake pedal hard to stop the engine, put it into park and release the brake, the engine doesn't start, yep.. even when foot is off the brake pedal. When you shift to drive, release seat belt or slightly tap the accelerator pedal, engine starts and i think that article is referring to this second part whereby even releasing the brake pedal, engine does not startup.
