OK we've looked at the basics so you should know how to handle your car.
That's just the start. Could you describe what your car felt like to drive
as this is important if you're going to be a first class driver.
There are lots of factors affecting your car's handling during the race.
You don't need to know the ins and outs of all of these,
what you need to know are the outcomes.
As your tires wear out and your car gets lighter, as fuel is used up, the handling will change.
Your car may start to feel 'loose' at the back end, also known as oversteer -
or you may feel though your car is 'pushing' towards the walls during cornering,
this is sometimes called understeer.
If your car were understeering heavily you'd have to slow down for each corner and you'd never get anywhere in the race.
That's if you even manage to take the corner!
Likewise if your car were oversteering heavily you wouldn't stand a chance.
It would be uncontrollable; you'd be fishtailing all over the place and would be lucky if you didn't spin.
Handling problems can be fixed in the garage;
in fact it's vital that you're happy with the handling before each race. But that's another lesson.
So what do you do when you've set your car up right but the handling changes during the race?
Well that's where your weight jacker comes in.
This car's about to take the corner.
This is the groove that this driver wants to take,
however if this car were understeering then the actual path the car would take, would look more like this.
And if this car were oversteering then the back end would turn more than the front end of the car making it unstable
if this were not corrected by the driver steering to compensate then the car would spin.
The weight jacker can be used to make small corrections to oversteer and understeer.
The effects are subtle so you shouldn't rely on it to completely change the handling of your car,
but it's important to know how it works.
By adding weight you can decrease understeer,
so do this if you feel the car pushing too much.
And if you subtract weight you can decrease the oversteer.
You should do this if your car feels too loose in the corners.
OK time to move on.
Another important skill in Indy racing is drafting.
This is also known as picking up a tow, or slipstreaming.
The way this works is like this. Basically, as the car in front cuts through the air,
the pressure in this draft zone is less than the air pressure outside  the zone;
basically there's less air, so there's less drag, and drag slows your car down.
You can see when you're beginning to draft another car, as your draft meter will start to fill up.
The more your draft meter fills the more your car is experiencing the effect of drafting,
which is reduced drag, and therefore, greater speed.
As your car speeds up the engine revs will increase so you'll need to change gear.
This is where the sixth gear comes in.
When you're in sixth gear you can use the extra momentum to get past your opponent.
However you can also use sixth gear to save fuel.
You don't need to overtake all the time to win at Indy racing you just need to cross the finish line first.
If you're drafting someone and you're in sixth gear instead of fifth then your revs will be lower,
which means your car will be using less fuel.
You can save about 5% of fuel a lap using this technique.
This brings us to the last thing for this lesson, your fuel mixture setting.
Here's the fuel setting indicator. It's currently set to four, which is normal setting.
Clicking it up increases the richness of the fuel.
You get extra speed but you burn more fuel.
Whereas clicking it down has the opposite effect.
You save fuel as the mixture is leaner but you go a bit slower.
You can also use a lower setting in conjunction with drafting to save fuel and keep your speed up.
Whenever there's a caution period, you should set your mixture to zero.
This saves you the most fuel but it's not only too slow for racing,
it will break your engine if you forget to put it back to setting four.
Just like the last test you're going to start off following the pace car as if you're in pole position.
When the pace car peels off accelerate to race speed and then complete three full laps.
And like before, you'll be on your own out there.
This time the time limit shortens as you complete each lap; so keep your speed up.
As before you'll fail if you come off the track or crash, or if you run out of time.
OK I'll count you in when you're ready.
Three, two, one, GO!
Well done you made it around. Bronze medal.
Good time well done. That's a silver Masterclass award.
Excellent time, great use of the racing line, you've got the gold.
That was close, but you're still not fast enough.
