Turned the coupe version of the BMW category 3 to a car with naming a class 4, some felt kind of strange resolved by BMW saying that the four doors categories and all copy will be charged Figure 3 vs. No. 4 for each copy of this car that relies on the principle of a coupe design . Despite the fact that most fans of the Bavarian brand managed to overcome the confusion caused by the label, but that a large number of them are still believed to abandon M3 and thus M4 for eight cylinders is normal and adoption of cloud engine to engine belongs to a club-cylinder six successive engines with turbo spoil things . Here, I can understand the reason for this because I am one of the plain clouds lovers engines that do not rely on additional shipping systems being able to provide torque in a continuous way as long as the driver presses the accelerator pedal, at a time when most engines fitted with turbo suffers from low effectiveness of the work of this the latter at low rotational levels which require the driver to be based on a minimum of gearbox ratios in order to keep the rotation in the case of high extraction can with something to hide from the effects of a turbo Tsaraeih.
Here, the owners of this theory will not be forced to more than leadership M4 and this is what I did for myself and ended with the conclusion that these theories totally wrong. Although the M4 lost two cylinder engine and relied on engine consists of a 6-cylinder with a capacity of 3 liters, but they benefited from the twin-turbo system was modified his standards helps the engine to provide the strength and resolve of starting from a low turnover levels until arriving at the medium-rotation levels and medium-high, which means that the pressure M4 (and M3 also) confirms that this car is able to provide sports to perform advanced, whether the engine rotation varies in the range of 3000.5000 or 7000 rpm because the extraction torque is constant and steady and rapid manner and as of 1850 and up to 5500 rpm. For those who believe that the absence of engine cylinders eight with normal clouds will lead to the loss of M4 to the roar of the sports Awadamha which rises with the height of the engine rotation, has proceeded BMW to supply the engine control unit work the engine works to control rotational levels and estimates the quality of Growl, which must be issued by the for you then compensate through the speakers sound music system that begins issuing sporty roar inside the cabin requires an expert in the roar of the exhaust to know that it artificially.
To compensate for the low effectiveness of the work of the turbo when the tee, will have one that depends on the Sport Plus program for Command, who is pumping small amounts of fuel in the cylinder when it lifted the driver's foot from the accelerator pedal or when you press the brake pedal, which can combustion process to continue and this is what Turbo device can continue to spin at a rate varies in the range of 120 thousand rpm. Once re-pressing the accelerator pedal, turbo turnover rises and begins to provide momentum and strength very quickly. Here, it must be noted that BMW engineers in collaboration with colleagues at the branch M sports they did an excellent job resulted in complete control with turbo that are responsive chalazia do it very accurately with the orders and the actions of the driver and that's what raises the response of the engine levels and can provide the performance very athletic ones M4 acceleration from zero to 100 km / h in 4.1 seconds. In this context, BMW adds that the transition from V8 engine plain to withdraw to the six-cylinder engine with twin-turbo did not contribute to the improvement of performance and fuel cut public weight lifting torque at a rate of 40 percent, but also enabled the M4 to be the consumption of the best 25 percent from the prior To reach the public consumption of 8.3 liters per 100 kilometers.
With BMW's announcement that the M4 engine generates power of 425 hp between 5,500 and 7,300 rpm coupled with 550 Nm can be extracted between 1800 and 5500 rpm, it was necessary for me to subject this car to a sports test and discovered that this car in a similar way transfer of force and torque to the rear wheels and driving them into the road to her sister, four-door, M3. Vantqal these powers to the smooth and silky road and try to make M4 slip if the device works Traction control, very hard so that this device senses Glides and intervene immediately. But when you stop the work of this device, you feel that the rear section of the M4 is coherent, but it is doing what he is doing consecutive slides, he feels very happy travels to you as a driver and paint a broad smile on your face, especially as the face of these slides are made by adjusting the pressure on the accelerator pedal Wolf the steering wheel to reverse sliding back. Here, the steering wheel plays an essential role being characterized accurately run high reinforced good ability to move under his front tires to the hands of the driver. The front suspension geometry and standards, Vthark from behind the wheel it works to your advantage as a strain in order to prevent slippage provided.
Here, one can not deny the role of the engine in the provision of this sporty fun. Although the capacity of the 3 quarts were distributed to the 6-cylinder and promotion double Ptorbu, but the BMW M engineers and Branch have considerable modifications to the engine in order to increase its capacity and improve its reliability. In this context, it has to strengthen the trunk crankshaft and reduce weight, at a time when you are relying on the axes of a vicious link from the inside to carry the pistons that move inside the cylinder is coated with a layer of nickel to reduce friction levels. Also, the M branch to supply M4 (and M3 also) the axis of transmission has its manufacture of carbon fiber and that after the adoption of the principle of vacuum inside it. Engine and transmission powers to the rear wheels, you are relying on the experience in the car automatic gearbox seven consecutive navigate through the lineage clutch double break is an upgraded version of gears that were available for the previous generation of M3 tray. The gear rear differential that distributes the forces of payment between the rear wheels, is a copy of the axis, which is available for two sisters M5 and M6 is equipped with a limited slip here the ability of electronically controlled and can of total closure under the influence of acceleration and braking. On the other hand, has been focusing on reducing weight through amendments to the engine and through the use of the front and back of the commentaries and specifically with the front wings and rear multi-processor links aluminum. Also, BMW has the adoption of carbon fiber for the manufacture of roof M4 and cover her belongings fund provider reflectors built-in air, compared to aluminum, which targeted some front fenders and hood and this is what enabled the M4 to be the weight of 1610 kg, less than about 91 kg of the previous generation.
In the face of enormous pleasure generated by a sporty driving this car on the road twisted and winding, it is sufficient that the M4 driver chooses the standard Comfort in your ways Command Control, which controls the work of the suspension and the steering wheel standards and responsive accelerator pedal, which is adopted usually everyday driving on the roads of the city, to feel that driving pleasure does not change only slightly so that Alankiedah tend to hardness even when adopting the standard Comfort and this is what always reminds you that you are not behind the wheel of any other car from BMW and the car that resides on the board sports wholeheartedly. Here, sports exhaust plays its role being enjoyed Bhder sporty fun not only to attract attention to the car, but also works on the enjoyment of present inside the cabin.
But from the outside, M4 depends on the design of the sister category 4 but also at home, add some modifications including obtrusive and large tires enable it to absorb light wheels Bkiesa 18 and 19 inches, embossed section in the center of the hood, side ventilation vertical slots, shocking Front athlete slots unique set of horizontal and vertical openings cipher which draws outside air into specific places behind and under the structure to contribute to the cooling processes that control and at the same time in a way the flow of air around and under the car to lift capabilities Altmaskeyh. As well as the unique M4 painted black color grille front ventilation slots, M logo on the front, side mirrors, curved design in the upper section of procedure to control air flow and reduce the noise at highway speeds and rear spoiler integrated into the top of the luggage compartment with a diffuser rear has a sports exhaust exits.
In short, we can say that what was done by BMW and branch M with this car is excellent, the car M has always been based on two key principles. The first sports Baltadah enhanced Bankiedah different from what is available in the automotive competition, while centered secondly about fun exceptional leadership. In these areas, I can assure you that BMW recorded a perfect score.
