Automotive pioneer
Karl Friedrich Benz is a German mechanic and entrepreneur, a pioneer in the automotive industry, officially recognized as one of the creators of the first car. Born November 26, 1844 in Ladenburg. Graduated from the "Higher Polytechnic School" in Karlsruhe. He worked as a photographer, watchmaker, laborer, draftsman and mechanic. In 1871 he decided to found a company for the construction of internal combustion engines, developed by him. In 1879, Benz tried to patent his motor, but it turned out that a similar engine had already been patented in the UK. Nevertheless, he received a patent, however, only for the fuel supply system used in his engine. In 1883 Benz founded the BenzandCompany Reinisch Gasmotorfabrik in Mannheim and began experimenting with building a motor carriage in his home workshop.
Slide 4
First car
In 1885, the first example of a 3-wheel vehicle with a single-cylinder engine appeared. It was an open carriage weighing 250 kilograms on bicycle-type wheels, with spokes, and the front wheel is much smaller than the two rear ones. The single-cylinder four-stroke engine produced 0.85 horsepower and 200 rpm. The engine was located in the back, under the seat. Its engine power was enough to accelerate the car up to 15 kilometers per hour. On July 3, 1886, Benz decided to drive his car for the first time to the streets of Mingheim, his hometown. Then the crackle of the engine and the very sight of the outlandish carriage frightened everyone. Benz built three of these machines in total. Two of them disappeared, and one is in the German Museum in Munich, and it is perfectly preserved, you can still ride it.
Slide 5
Mercedes Benz
On January 29, 1886, the inventor received the German Imperial patent for a "gas-powered carriage" called "Motorvagen". In 1893, Benz began producing the 4-wheeled Victoria with a three-horsepower engine, and in 1894 the Velo model went into production. By the beginning of 1901, Benz's company had become one of the largest in the industry. In recognition of the merits of the engineer, the Higher Polytechnic School in Karlsruhe awarded him an honorary doctorate. In Russia, the first Mercedes-Benz car with a capacity of 1.5 liters with two seats appeared in 1894. First sold in 1895 in St. Petersburg. Subsequently, the first Benz car became the prototype of the first Russian production car of the Petrol and Gas Engine Factory of the industrialist Yakovlev in St. Petersburg.

Car classification
A car is a self-propelled vehicle designed to transport goods, people and perform special tasks. Passenger cars are designed to carry from one to seven passengers. Buses are designed for mass transportation of passengers. Buses, depending on the destination, are intercity or city. Tourist buses form a separate group. Depending on passenger compatibility, buses are divided into buses of small, medium and large compatibility. Trucks can have a platform and can be used as universal vehicles for transporting various goods and can be specialized, with bodies adapted to transport individual loads. In addition to the body type, trucks are classified according to their carrying capacity and maneuverability. Special vehicles are designed to perform one task. These include: firefighters, sanitary, aerial platforms, watering, auto repair shops. * Vehicle classification can be seen on the diagram

Rationale for the choice of topic
The theme "Cars - Old and Modern" was chosen by me because I love different cars. Cars are very important for a person, since in the modern world, a person himself can no longer cope with the rhythm of high speeds. Cars play an important role in everyday life, including taxis, ambulances, fire trucks, rescue vehicles and many others.
Slide 3
Purpose of the research: to study the history of automobiles. Research objectives: 1) Collect information about the development of the car; 2) Carry out the classification of cars; 3) Conduct a survey among class students; 4) Draw conclusions on the research topic.
Slide 4
Automobile Automobiles have been around for over a hundred years. The word "car" consists of two words: the Greek "auto" means "itself", and the Latin "mobile" means moving. " All together it translates as "self-propelled". The very, very first car was designed by the Frenchman Nicolas Cugno in 1770. Karl Benz's car, 1885. The first production car with an internal combustion engine.

What does a car consist of?
The body is the main part of the car. The engine is the heart of the car. The most important part of the car. Thanks to him, the car moves. The chassis is the base of the machine. Salon - passengers and cargo are accommodated here. Trunk - to accommodate luggage.
Slide 7
Safety
The development of the automotive industry has led to an increase in the speed of movement, an increase in the number of cars on the roads. More and more accidents happened. In 1909, uniform rules were adopted for all countries, the first road signs were introduced, and the duties of drivers and pedestrians were established. In 1914, the first traffic light appeared. Also, one of the most important areas was to increase the safety of the car itself. This is how bumpers, belts, airbags and various systems appeared.
Slide 8
Poll Investigating this topic, I conducted a survey among classmates, in which the following questions were proposed: What brands of cars do you like? Why do you need a car in the first place? What should be the car of the future?

The consultants working in car dealerships describe the models of cars in some detail and in detail, and in this one can feel their knowledge of the business and the full characteristics of cars. To achieve such a high level, you need to constantly read car reviews, study special literature and information about new cars. In this process, the main thing is that consultants do not use many technical terms, because you cannot show the client your superiority over him.
When dealing with potential buyers of a car, a manager should not make gross mistakes and belittle customers. A huge typical mistake car sellers make is their assessment of the purchasing power of customers, which is based on the demeanor and appearance of the latter. Car dealership managers must show visitors any car that the client asks about, the consultant should not, by his behavior, make it clear to the visitor that the car may not be affordable for him, this even applies to working with the most expensive cars.
Today, there are many credit programs in domestic countries, so many car dealership clients opt for cars that cost much more than they can afford, so when a car dealership manager tries to decide for a client the acceptability of the cost of the car they buy, it will be generally unreasonable.
In most cases, consultants limit themselves to demonstrating only the car that the visitor wanted to know about. Some car dealerships even offer potential buyers to get into the car, but this is done only in those places where customers have low expectations and demand exceeds supply.
The car for sale should be shown in action, for this you need to turn on the ignition so that you can press all the buttons and so that all the lights come on. To this end, many car dealerships offer the popular test drive service. If this service is not offered for certain models, the manager can take the buyer for a ride through the nearby streets or the backyard of the car dealership.
In order for the buyer to feel comfortable in the car (albeit a stranger for now), it is imperative to adjust the mirrors and the seat for him.
At the present time, credit systems contribute to the rapid development of the car sales industry. Therefore, when the consultant of the car dealership starts to demonstrate the car, the visitors of the car dealership forget about their other needs and decide to buy a car that may not even be affordable for them. In such cases, emotions prevail over the mind of the buyers and the manager must be able to use such moments.
Inexperienced or lazy car dealership managers cannot captivate buyers, they do not offer visitors to show the car, they do not take the initiative and do not dare to help the client choose a model. Therefore, the consultants of car dealerships should think for the visitor, guess his innermost desires, offer different versions of the car, willingly share their own experience.
During the presentation of the machine, the seller must pay attention to the buyer's requirements. Often, inexperienced managers do not ask any questions at a car dealership, so they create the impression that they are afraid to invade the personal space of buyers and ask something. The seller of the car must master that it is the question that is the real tool for selling, and it is precisely the correctly asked questions that most often lead customers to a purchase, and even faster than the most complete and wonderful information about the car.
In some cases, managers can get so carried away by stories about the car that they simply do not have time to talk to the visitor, since other customers are waiting for them at the car dealership. Therefore, in such cases, it would be better to ask clarifying questions after the presentation of the car. If the questions of how the most powerful tool for selling cars are not fully utilized, then the manager loses his potential buyers.
In other words, often visitors to car dealerships who have money leave with nothing and the fault is the manager who did not want to understand the client and satisfy his desires. Therefore, the sales volumes of car dealerships turn out to be too low and the reason for this is that sellers do not ask customers questions.
