2012 MINI Cooper S Coupe test
The new MINI (yes in capital letters, the original is: Mini), has become a true modern icon. Because of the position in a proportion of premium compact car with a large circle of customization available and enjoyable handling, is the team to beat in its class.
This year, our country, came the coupe version of the same exterior design continues this line of success with other products of the brand, but it becomes more personal and sporty thanks to the loss of the rear seats and much too aggressive roofline also more likely glass.
With the new members of the family, the MINI brand will attack a segment that does not mind not having the back seat, but want fun to drive coupe with an attractive design.
Mechanically the same as his brother, MINI Cooper S, so mounted 1.6L four-cylinder twin-scroll turbo (developed by BMW and PSA Peugeot Citroen) who gives the power (for its size and weight) is ignored 184 hp and torque of 190 lb-ft of which can be coupled to an automatic transmission as in the case of our test car, or, manually operated two of the six changes that are very good and enjoyable.
Internal changes are most obvious is the lack of rear seats that also benefits the cargo space and now it makes luggage to carry more luggage does not like a normal hatchback.
Management, although very similar to the Cooper hatchback, this feels more driver-oriented, definitely a different setup, much more aggressive since the handover of power to the hard suspension (which makes us suffer on bad pavement condition). Everything is made to communicate what passes under the wheel deals a more direct way to the driver.
Personally, I found the MINI coupe and my favorite line so far (it will take a roadster version has been delivered). Having a design that I wanted to be more aggressive and sporty, plus you have a standard size rod and no room in the back and in the trunk, mediocre or serve very well for carrying people or luggage.
For this and fun to drive, is that the 2012 MINI Coupe cannot miss our selection of the best sport to begin this year.
BMW 3 Series 2012 A German model was tested
BMW 3 Series 2012 A German model was tested by the best magazines in Europe – Speaking us no more and no less than one important model in the category of middle-class sports car like the BMW 3 Series, and talking to the opposite one of the best magazines such as AutoCAD, not only in Germany for example, but all of Europe, today we will have little mixing will produce the best magazine in Europe have done a better test vehicle, the BMW 3 series.
Now that we’ve talked too, will pass directly to the information, and as the data is not just a simple comment that the magazine did a test and tell them a little, but soon we prefer to show them the video of Coach we have shown to us, so no one lost along the way.
AutoCAD tested the F30 BMW 3 Series for the sport of precision, the new models can we trust wholly owned by a group of German vehicles in the world, but for those who want more specifics, we can count on him to have an engine that uses gasoline, 2-liter turbo and no more and not less than 245 hp, a combination called Twin Power details. Appears in combination with 7-speed automatic transmission.
The award, so to speak, which gives the magazine, went to the first frame, able to provide a sense of light and incredible precision given the size and mass of the vehicle and in line with the traction of the German company, but also changes in the character of the electron configuration of the car clearly visible.
History and Development of an automatic transmission
The development of the automatic transmission goes back to the early years of the 1930s, although the first true automatic transmission (no clutch needed) did not appear in the production line until 1939. His story begins in the Ford Model T, which operated planetary gear with your foot, took part in the drive more than 15 million units out of the assembly line entre1908 and 1927. They also helped the achievements of other companies: Chrysler working on developing hydraulic drive and hydraulic control system for General Motors and its torque converter as most significant.
It was the Hydra-Mastic division of General Motors, formerly the Detroit Transmission Division, which initially completed the first fully automatic transmission-line models in October 1939, six months after they formed this division. Their transmissions were made for Oldsmobile. A year later, Hydra-Mastic transmissions produced about 220 daily, and began shipments to Cadillac. Automatic transmissions are used in some military vehicles during the years of war, and its continued development led to the torque converter, an ingenious drive coupling, hydraulic, which almost did not transmit torque at low vehicle speeds, but at cruising speed was a very efficient hydraulic coupling.
By 1950, all major automakers offered automatic transmissions, and soon after was offered on many models as standard equipment.
So we can say that the main elements of the automatic transmission-fluid coupling, planetary gears and hydraulic control systems, appeared in the last years of the 1940s. Since then, engineers have changed the design, implementation and location of these elements, but have not made major changes or additions to the elements themselves. There have been other developments such as the gearbox controlled by computer, which appeared in the early years of the 1980s, but the same automatic transmission from the driver’s point of view has changed little since 1948.
