Why are good cars so long? For example:

Only a longer body can have a longer wheelbase, and a long wheelbase is a key factor in determining the longitudinal space in the car.

The wheelbase is long, the space is large, the stability is good, the comfort is strong, and the grade is high.

A-class (including A0, A00) cars refer to small cars; The B-segment is a mid-range sedan; The C-segment is a premium sedan; The D-class car refers to the luxury car, its grade division is mainly based on the wheelbase, displacement, weight and other parameters, the lower the alphabetical order, the longer the wheelbase, the larger the displacement and weight, the luxury of the car is also constantly improving.

The wheelbase of the A00 class sedan should be between 2 meters and meters, and the engine displacement should be less than 1 liter, for example, Alto belongs to the A00 class car;

The wheelbase of the A0 class sedan is from meters to meters, and the displacement is from 1 liter to liter, which is more typical of the hatchback Xiali sedan;

Generally speaking, the wheelbase range of the A-class car is about between meters and meters, and the displacement is about to rise, and the Jetta of FAW-Volkswagen and the Polo of Shanghai Volkswagen can be regarded as the stars of the A-class cars;

In recent years, the B-class car market has gradually become the main battlefield for domestic automobile companies, Audi A4, Passat, China, Oriental Son and many other models belong to the B-class car camp;

The wheelbase of the C-class high-end sedan is about between meters and meters, and the engine displacement is liter-to-liter, and the most famous C-class car in China is none other than the Audi A6;

Most of the D-class luxury cars have a magnificent appearance, the interior space is extremely spacious, the engine power is also very strong, the wheelbase is generally greater than meters, the displacement is basically above the liter, the current common D-class cars have Mercedes-Benz S series, BMW 7 series, Audi A8 and Rolls-Royce, Bentley and other brands of models.

Hello dear, <>

Glad to answer for you, the long, long car is the longest car in the world designed by Jay Olberg in Burbank, California, USA, this is a premium sedan, the length of meters, there are 26 wheels underneath, it looks almost like a small train. Olberg has designed a series of extra-long sedans with many luxurious amenities inside, which make them longer, including swimming pools with springboards, luxurious suites, and oversized water beds. The designers of the supercar not only made the supercar superior to the competition in terms of length design, but also in auxiliary equipment.

Even more peculiar is the fact that there is a small swimming pool at the rear of the sedan, and the lid of the swimming pool has a landing cushion for a straight sail lift. You can let *** stop directly on the top of the car. Driving with such a long steam key belt open also requires a unique technique, which can be driven as a stable car or in a mid-curved manner.

Good cars are wider because the car is wider and more stable to drive, especially when walking on a hill road, it is more obvious.

The reason why a good car is wide is because a good car has a high configuration and a lot of space, so he needs to make his car wider to meet such needs.

The idea that the heavier the car, the better, comes from some "old drivers", because the technology and materials used to make cars were far less advanced and advanced than they are now. At that time, whether a car is safe, strong and reliable, depends on the thickness and thickness of the body in the steel plate and steel beam, the thicker the steel plate, the thicker the steel of the body girder chassis, the stronger and safer it is, but the weight is also proportional to the up, so there is a saying that the weight of the car is good (the weight of the car indicates the thickness of the steel plate);

But in this era, the car manufacturing process, materials, technology has made great progress, many cars are used high-strength steel or alloy, the weight is half of the previous one, the strength is several times that of ordinary steel, the weight of the car is not high, but it can be very strong and safe; And under the current increasingly strict emission standards, reducing weight means reducing fuel consumption, that is, it can reduce emissions, and cars that meet the emission standards can be legally listed**. This is also the reason why many well-known car manufacturers are now trying their best to reduce the weight of the body; For example, the BMW 7 Series uses a lot of carbon fiber materials (30% lighter than aluminum, 50% lighter than steel, but 7 to 9 times stronger than steel), and the maximum weight reduction is 130 kg compared to the previous generation 7 Series;

In terms of power, braking and handling of the car, a lighter weight can achieve better handling, reduce the load on the engine, and reduce the braking distance.
