BMW 1-SeriesBMW has officially presented the stock sedan BMW 1-Series. This model was developed by the German company together with the Chinese car manufacturer Brilliance. The assembly of four-door saloon will be realized by China at the co-enterprise of BMW and Brilliance — BMW Brilliance Automotive Ltd.

The sedan BMW 1-Series was developed especially for the Chinese market. The model was developed by the experts from the headquarters of BMW in Germany and the Chinese engineers. The road tests of the four-door saloon were realized in the different regions of China in different weather conditions and on any roads.

There are no technical details about the sedan 1-Series in BMW. The edition “Motor1” suggests that the model is built on the front-wheel-drive platform UKL that which forms the basis of the latest novelties from MINI and the compact vans BMW 2-Series Active Tourer and Gran Tourer.

The concept predecessor of BMW 1-Series sedan is the prototype Concept Compact Sedan with 2010 Chrysler Town and Country fog light bulb, The concept car debuted in November 2015 at the Guangzhou Car Show.

Renault KoleosFrench cars are traditionally encouraging by its originality and the new Renault Koleos is a good acknowledgment. This is surprising practical, compact, maneuverable and functional model that can give pleasure to any driver, without exception!

Affordable price of modern crossover Renault Koleos gives the opportunity to buy it by any buyer. The car features a modest design, which is characterized by the presence of a chrome grille, excellent optics and specific corporate style of the producer. Comfortable cabin is equipped according to the latest technology and boasts everything you need: climate control, navigation, and a glass roof.

A distinctive feature of the Renault Koleos is rightly recognized two-folding rack. Its advantage is that it can not only be used for different applications, but also as a seat or table. The presence of a specifically required transformation mechanism can significantly increase the amount of luggage with just one movement of the lever.

Robotic gearboxTo understand how the robotized gearbox works, it is necessary to imagine the usual “mechanics”. The only difference between them lies in the fact that by closing / opening the clutch and gear selection in a “robot” are made by servo – actuators. Most often it is a stepping motor with gear and actuator, but there are also hydraulic actuators. They are managed by the electronic unit. By command of electronics for switching the first servo clutch, the second one moves the synchronizers, including the right gear. Then first one slowly releases the clutch. That’s all.

It would seem ideally, circuit is simple, highly efficient, and less than a torque converter, fuel consumption. But there is a catch: in order to avoid jerks and not mock-clutch during switching transmission, “robot” permanently severs the connection between the engine and the wheels, which is why during the dispersal there are unpleasant failures, get rid of that is only one way – to reduce the time of switching.

Traction ControlIf the angular sensors of wheel speed are recorded slipping, the system depending on the settings can reduce the supply of fuel and reduce the engine torque, or brake the slip wheel, or do everything simultaneously. A system is particularly useful on slippery surfaces. It also can prevent wheel spin during the throttle in the corners, thus not allowing develop a skid of the rear axle on the rear wheel drive cars and demolished of the front one on the front wheel.

The system has a positive effect on the stability and safety of the vehicle, especially on slippery surfaces, preventing driver excessive pressing the gas to cause a critical situation. But it can do a disservice traveling through deep snow, sand or mud, “choking” the engine just at the moment when the car needs the maximum gas to a slipping out of the unstable surface. Therefore, to drive on the sand or snow (at low speeds) Traction Control is disabled as needed in advance.
