A place to discuss the characteristics of the cars in Formula One, both current as well as historical. Laptimes, driver worshipping and team chatter do not belong here.
The Red Bull (2011) has a purity of lines denoting obsessive detail work at the rear end of the car, who has taken to the extreme the concept of miniaturization of the components of the transmission of the rear axle, radically to encapsulate the mechanical and free up as much space, which allows you to maximize aerodynamics in one of the most complicated and sensitive parts of a car. The back of Red Bull was the narrowest, thin and closed around the paddock for the greater glory of aerodynamic efficiency.Also they got the famous Exhaust Blown Diffuser, a diverging and expanding duct creates low pressure area under the car, creating downforce. The idea is to harness the gases leaving at high speed through the exhaust to produce downforce.
But its effect depends on the engine (controlled by the accelerator pedal by the driver) . With the accelerator fully depressed would have the maximum benefit, without pressing the accelerator there would be no benefit.
Did you hear the Honda engine crackling noise when they downshift through the curves? That's the exhaust gases being channeled through the diffuser. This seems to be the "new technology" Ron Dennis was talking about.
If Honda and Peter Prodromou hit the target with de MP4-31... What do you think?

"Some of the technologies that have been introduced to the power train haven't existed before," Ron Dennis (2015)
So, we all don't know except Honda and McLaren.
With the greatest of respect and consideration for your enthusiasm, non of that is possible with current regulations.
Also, with a little research you will soon learn all about what is commonly referred to as "Ron speak". Ron is referring to the unique layout and packaging of the Honda PU. Have a read of the Honda PU thread.
The exhausts were used to add energy to vortecies that were at the either foot plate of the diffuser. This had two consequences, first it sealed the floor from turbulence caused by the tires. The second benefit is quite a bit more complex, but in simple terms it made the diffuser work harder than it otherwise would have. Not in terms of outright downforce, but when that downforce kicked in.
Red Bull had the most advanced blown diffuser, and it allowed them to carry a very low profile rear wing and still have comparable downforce. In fact I'd be willing to bet they had the most low to mid speed downforce out of any other car.
If you look at the timing for the Indian GP, you can see the HUGE advantage Red Bull had, especially in the final sector which is all low to mid speed long sweepers.

Actually, exhaust diffuser blowing did work “off throttle”. The fuel flow was maintained while the engine power was shut down but the ignition system. The hot exhaust ignited the fuel.
^Renault was the engine manufacturer to have the best off throttle exhaust characteristics, they tuned and supplied RB with engine maps that maximised off-throttle exhaust mass flow.
Renault engine did lack outright power but this was its strength, along with better fuel consumption.
