My wife was cheated by me in an instant. She was stupefied for five seconds and asked me: You made Citroen so awesome. What is it like now? Is it not clear that you are an automobile professional? ? I shouted: son! Get down. ? Let's get to the point. Let's take a look at those "firsts" that changed the history of world automobile development! ? Citroen traction? Avantgarde? ▼? The originator of front-wheel drive cars? Innovative hydraulic brakes? New self-supporting all-steel body? Suspended engine
1934, Citroen 7A came out. This is the first front-wheel drive car, which shocked the whole automobile industry with its bold technology. Traction? Avant is a real technological revolution, which received rave reviews as soon as it appeared: "Novel, bold, rich and unique solutions are beyond the past". Cars have been produced until 1957, and * * * has produced 760,000 cars.
What is worth mentioning is traction? Avant has assembled many advanced technologies of that era. In addition to the precursor technology, there are innovative hydraulic brakes and suspension engines (chassis body integration), and the new self-supporting all-steel body is used to accommodate these technologies. ? ▼
The car body was jointly built by engineer Andre Lefebvre and Italian sculptor Bertoni. The streamlined appearance designed according to aerodynamic principles makes it look elegant, light and charming.
On the basis of innovative application of advanced self-supporting all-steel car body, the streamlined car body designed by engineer Andrei Lefebre and Italian sculptor Bertoni is adopted for traction, which organically combines lightness with aerodynamics.
As of July 25, 1957, when the last car was pulled off the production line, the output of this car reached 759 123, which took * * * 23 years and 4 months to produce 15 days, setting a world record for the production time of cars at that time. In addition, traction used to be a symbol of identity and status. It was once the "mount" of General Charles de Gaulle on the battlefield, and it was also the designated car during his presidency. Even now, many fans and collectors all over the world still cherish this legendary traction. ? The first automatic car? ▼? Model: Ford model t? 1908, Henry Ford equipped the Ford Model T with a 2-speed automatic transmission. Although simple and reliable, it is not very convenient to operate, because it requires the driver to know clearly that when the transmission shifts gears, it needs the cooperation of the throttle to drive the vehicle smoothly. ? Making the automatic transmission truly practical and reliable was the goal of all automobile engineers at that time. But maybe everyone can't think of it. What really stimulates the development of this technology is not to make people drive more comfortable, but to make cars no longer easy to stall on the battlefield.

By matching more reasonable valve opening or closing time for vehicles with different speeds, the balance of vehicle torque output is enhanced, engine power is improved and vehicle fuel consumption is reduced.
