Dr. Singh said happily: "Mr. Philip, show us the small car you have designed for the masses!" We are also curious about how it differs from the national car that Chancellor Hitler positioned! ”

Xiao Weiguo nodded and said: "Okay, in fact, I drew a design sketch last night, you can take a look, and then you can also make a little suggestion, this is a model that can be revitalized by the BWM company in the next few years." We've got to hit the bullet! ”

After speaking, Xiao Weiguo took out a piece of paper from his pocket, and when he unfolded the drawing, everyone saw a car completely different from any kind of sedan appearance presented in front of them. It is said to be a sketch, in fact, Xiao Weiguo drew this picture in detail, and this is a three-dimensional diagram, so everyone can clearly see the shape and interior of this car, and even mark the relevant data next to it.

Seeing that everyone's eyes were so surprised that their eyeballs were about to fall to the ground, Xiao Weiguo was also very proud, although this was a bit of a suspicion of plagiarism, but the car he drew was different from the small entry-level car in the future time and space, its appearance was more beautiful, and the space was also enlarged, mainly to increase the size of the trunk.

Xiao Weiguo said excitedly: "Everyone, please see, I named this car BMW Mini Car!" It is said that it is a mini car, but in fact its size is not small. You see, it has a length of 3.8 meters, a height of 1.55 meters, a width of 1.65 meters, a wheelbase of 2.45 meters, and a weight of 800 kilograms, including passengers and luggage, and 1,250 kilograms. With such a size, it can seat 5 adults, and as long as you are not too fat, you can sit 3 people in the back seat. We can develop a gasoline engine with a displacement of 0.8 liters and a power of about 50 horsepower, although it is still difficult to develop such a high-power engine. But we can transplant some of the technology from the aero engine, and it shouldn't be much of a problem. ”

Lucas nodded and said, "Philip, my God, is this car you designed to blind everyone's eyes?" It's a car like no other! Not only is the appearance cool, but also the space is also very large, so it can't be called a small car at all! This space is not much worse than a luxury sedan. This design is very compact, with a 3.8-meter-long body, so much space. And it also looks very aerodynamic, and it should be good in terms of speed. In terms of engine research and development, we can use a large number of aluminum alloy materials, which can reduce the weight of the engine, including the body can also use a part of aluminum alloy. It should be no problem to achieve a vehicle weight of 800 kg. ”

Dr. Singh agreed: "Mr. Lucas is right when he says that there are two main measures to reduce the curb weight of the whole vehicle. The first is that the newly designed model should make its structure more reasonable, and the second is to use lightweight materials with sufficient strength. And the shape of the car is indeed an innovative and unique design, with a streamlined body, which can greatly reduce air resistance. Nowadays, the speed of cars is getting faster and faster, from the initial ten kilometers per hour to seventy or eighty kilometers per hour, at this time, the air resistance, stability and comfort problems brought by high speed have been bothering us designers. I didn't expect Mr. Philip to solve this problem easily. Now those box-like box cars, I think they're going to be phased out very quickly. A BMW mini car like Mr. Philip's design, with its sleek exterior, closed cabin and streamlined shape, is sure to be the most popular car shape! ”

Delort also said excitedly: "Mr. Philip, your design is really amazing! I think that when this car is released to the market in the future, it will definitely cause a sensation all over the world! It is even possible for us to take the position of the hegemon of world automobile manufacturing from the American Ford Motor Company! ”

Xiao Weiguo knew that even if Porscher's Beetle could be produced earlier, it would not be able to compete with this futuristic BMW mini car. Because the disadvantages of the Beetle car are obvious, it has little space for passengers to move. In particular, there is a sense of pressure on the top of the head of the rear passengers, and due to the asymmetry between the front and rear, its anti-cherry blossom windward stability is very poor, and the car is easy to deviate from the driving route under the action of crosswinds.

Xiao Weiguo nodded and said, "Yes, we just have to have this confidence!" Although the American Ford Motor Company invented assembly line production, the world's automobile was introduced into a new era of mass production. And Ford Motor Company's Model T car, as early as 10 years ago, sales have exceeded 1.9 million units, and the price has also dropped by less than 300 US dollars, that is, about 1200 marks, throughout the 20s, almost half of the world's cars are Ford's Model T! But a new era is coming, and our BMW mini car must break the sales record of the Ford Motor Company's Model T! Although we are facing competitive pressure from such strong players as Hellam Benz and Porsche, as well as Ford and General Motors in the United States, we must buck the trend! ”

Dr. Singh looked at the drawings and continued: "The front-wheel drive design of this car is even better! The car engine, clutch, transmission, final drive, differential are assembled together to form a complex and compact whole, which is fixed to the frame at the front of the car, and the front wheels become the driving wheels. This design is really novel, and now the mainstream rear-wheel drive design has too many shortcomings, and it is very complicated to operate! ”

Xiao Weiguo said with a smile: "Indeed, the front-wheel drive car has not yet appeared!" But there are a lot of advantages to this solution. Front-wheel drive is a lot cheaper than rear-wheel drive in terms of both manufacturing and installation. It didn't pass through the drive shaft under the cockpit, and there was no need to make a rear axle housing, the transmission and differential were assembled in a single housing, so fewer parts and components were required. This front-wheel drive system also makes it easier to install other components under the car, such as the braking system, fuel supply system and exhaust system. Another advantage of front-wheel drive is the reduced weight of the entire vehicle. Reducing vehicle weight can improve acceleration, braking and fuel economy. Since the drive wheels of a front-wheel drive car bear the weight of the engine and drive axle, the adhesion of the drive wheels can be increased, which will be of great help to the car driving on slippery roads. The biggest advantage of front-wheel drive is that it can have a large interior space, and there is no large bulge in the cab because of the drive shaft passing. Take a look at this BMW mini car and you'll see that this kind of car can also have a lot of rear seat space that many sedans can't match, thanks to a flat floor and at the same time, without a rear differential, the boot space will be increased. ”

Singh nodded and said, "In addition, the hatchback rear door of this car is also a very good design!" Its roof is longer than that of the foldback, while the rear window and rear trunk lid form a single rear door. This greatly increases the volume of the suitcase! (To be continued.) )
