Motor racing is a funny old business.

We make a new car every year,

and then we spend the rest of the season

trying to understand what it is we've built

to make it better, to make it faster.

And then the next year, we start again.

Now, the car you see in front of you is quite complicated.

The chassis is made up of about 11,000 components,

the engine another 6,000,

the electronics about eight and a half thousand.

So there's about 25,000 things there that can go wrong.

So motor racing is very much about attention to detail.

The other thing about Formula 1 in particular

is we're always changing the car.

We're always trying to make it faster.

So every two weeks, we will be making

about 5,000 new components to fit to the car.

Five to ten percent of the race car

will be different every two weeks of the year.

So how do we do that?

Well, we start our life with the racing car.

We have a lot of sensors on the car to measure things.

On the race car in front of you here

there are about 120 sensors when it goes into a race.

It's measuring all sorts of things around the car.

That data is logged. We're logging about

500 different parameters within the data systems,

about 13,000 health parameters and events

to say when things are not working the way they should do,

and we're sending that data back to the garage

using telemetry at a rate of two to four megabits per second.

So during a two hour race, each car will be sending

750 million numbers.

That's twice as many numbers as words that each of us

speaks during our lifetime.
