Transcript of Car Prezi

The wheels are powered by the driveshaft connected to the transmission, which is connected to the engine. A bigger engine gives more power to the drivetrain and has the car go faster in a less amount of time. Transmissions are in all car, but they are very useful when in racing to change gears in a split second to maximize efficiency. Brakes are on every car, but racing brakes can slow down a car so much it produces up to 3.25g's, whereas stock car brakes will lock more easily and take more time to stop the car. To maximize fuel efficiency, regular cars do not have down force produced by their body. Down force puts a greater load on the engine. Suspension is also very important. It consists of pistons or springs that suspend the rest of the car above the wheels and drive shaft.
Well, you might be thinking, do some of these vehicles even look like cars?
Internal parts must be high end
Must be aerodynamic
Must have a driver that can drive the car
Standards of a Racing Car
This IS NOT it!
This IS a racing car.
This is nothing but a simple Honda Civic with a different exterior that does nothing but slow the car down. This is what the racing world calls a "Ricer".
This is an LMP2 class car that will go 0 to 60 in about 2 seconds. This is a real racing that has all the features of one.
(Vroom vroom vroom) :P
The cars that were shown in the video demonstrated all of these things. The weird shapes you saw were to make the cars more aerodynamic. You can't see this, but the cars are constructed from carbon fiber, a substance much light, yet stronger.
You know what a racing car is, but where and when do they race?
Lauterbrunnen, Switzerland
Le Mans, France
Circuit de Catalunya, Spain
Nurburgring Nordschleife, Germany
Montserrat, Spain
In the video, the race track shown was Le Mans, France. This is where a 24 hour race takes place every year. Auto manufacturers come from all around the world to fight for the title of Le Mans Champion.
So what happens on race day?
The racing crew must make sure that the high tech car is running smoothly and prepared for a brutal race.
The race starts and the cars are off!
Yes, it's a crash. This is probably the most exciting, yet depressing part of the race. Crashes are very costly, not only because the car is more than a million dollars, also because the driver is at risk.
The racing crew of the driver prepares the car so that it can be pushed to its limits without breaking. A new car is built every year by the car manufacturers. That means that the cars retire after only maybe a thousand miles. Cars should not be reused because that can compromise performance.
There is usually one driver in a seat, with a prototype car, but when there is an empty seat, it usually holds radio equipment, not another person.
Unlike NASCAR's, these car need headlights because they race at night in long endurance races.
How Does a Car Work?
How Does an Engine Work?
How Does a Tranmission Work?
How Do Suspensions Work?
These are racing cars, of course they don't!
Racing Classes

Air Intake

Racing Cars Class
Air Intake - The air forced into the engine so that combustion can happen inside and move the car.
Concept Cars - A concept vehicle or show vehicle is a car prototype made to showcase a concept, new styling and new technology.
Economic Cars - Cars that are made solely to get from place to place that usually are cheaper than other cars.
Chassis - The main body of a car usually made from aluminium, steel, or carbon fiber.
Combustion - Gasoline that burns inside of the engine to create heat and fire.
Engine - The part of a car that gives produces the power necessary for the car move.
Motor - The part of an electric car that propels the car rather than an engine.
Supercharger- An air compressor that use a pulley connected to the engine to compress the air inside it.
Transmission - The part of the car that shifts gears in order to the power from the engine to be used on the wheels.
Turbocharger - An air compressor mounted to a car that uses the gases from combustion to increase the amount of power that is put out by compressing the gases in the engine.
Prototype cars are expensive to build, plus the cost of the driver, pit crew, transportation, lodging, and food. Sponsors pay money to the car manufacturer in return for advertisement.
The most important part of the car. He or she is the one that pushes the car to the limit and fights for positions. This driver is a dare devil, even though it may not seem like it
Before you learn about prototype cars, you should know some basics about regular cars.

In Conclusion...
Car racing/prototype racing is fun to watch for people of all ages. Cars are also a common hobby among many people that enjoy going fast or working on cars.
