This week’s tip will not be about this layout or any specific corner. The track is simply to big with so many challenges it would be deserving of a full series on its own over a few seasons. What we will focus on though are the concepts we have been speaking about in the tips up until now. Aspects of cornering. I have obtained the permission of the author, Scott Mansell to share his information found at https://driver61.com/uni/
You should visit that site if you care to learn the finer point of many driving skills.
As there is a lot of information here I am going to post a little more each day for the next week.
This is from his section "The six phases of a corner"
There are six phases to any corner, which you can see in the diagram below and are as follows:
Braking and downshifting
We’ll head into more detail about each section in a little while, but to be more clear let’s take a look at the graph below. This chart describes what we should be doing with the pedals at each point through the corner.
We can see pedal pressure or percentage against distance where the green line is throttle position %, and the red line is brake pressure %. As you can observe, we’ve split the distance axis into six sections which correspond to the corner diagram.
The first line you can see (to the left of section 1) is where the driver is at 100% throttle before the corner – he is flat out before he lifts for the braking phase.
Phase one of the graph shows braking pressure from 0% quickly up to 100%, where the pressure stays while the car is in a straight line and at maximum braking capacity (see corner diagram).
Phase two shows a smooth blend off the brakes as the car begins to enter the corner. Notice that this step takes some distance and the pressure is released slowly.
Phase three explains the area where neither the brake nor accelerator is being used. This is the transition time of your foot from one pedal to the other.
Phase four shows the balanced throttle stage, where the driver is re-engaging the engine to maintain speed – not accelerate. Just like the final part of the trail braking phase, notice how smooth the initial application of the throttle needs to be.
Phase five is where the driver begins to launch the car out of the corner, increasing the throttle position and decreasing steering angle – the further out of the corner the driver is, the quicker the increase in throttle position.
And finally Phase six – the point where you finally have the confidence to go flat out and get to 100% throttle!
Cornering Phase 1 – Braking and Downshifts
Almost all of the deceleration before the corner will take place in this first phase. The car should be in an entirely straight line – like this you can use 100% of the car’s grip for slowing down (as soon as the car turns even a little, you’re taking grip away from braking).
It sounds obvious to say that you should spend as little time braking as possible, but this is a common loss of lap time even for experienced drivers. We’ll have a more detailed tutorial on braking later in this series.
Spending as little time on the brakes as possible is critical for lap time, but what’s more important is to arrive at the turn-in point (around phase two) at the correct speed for the corner.
Arrive too fast and you’ll overshoot the corner and ruin your exit. Arrive too slowly and you’ll have lost time in this braking phase. There’s a sweet spot and, to consistently arrive at the correct speed, you’ll require good track vision – something we’re going to cover in the next tutorial.
Another thing to note in this phases is that if we’re decelerating a reasonable amount, we’re going to need to downshift. Gear changes should be evenly spaced through the braking zone and as always be as smooth as possible. For extra smoothness, you can learn how to heel and toe here.
