Test drive BMW 3 Episode F30 since 2012 sedan

TURBOPROP

She is such a life - she will definitely correct. For two decades, BMW experts tirelessly kept saying that boost is not our method and that only atmospheric engines are able to give the driver the very pleasure of the wheel that was drawn at the armor of the Bavarian company. And the interculers and other compressors let them remain the lot of those whose customers are satisfied with sitting in turboers. And here we have a new compartment of the 3rd series, the engine of which is equipped not by one turbine, but at once with two.
Of course, the boosting engines are different, but the stereotype of their behavior in the minds of consumers, who do not care, approximately like that. You do not go on two thousand revolutions, but you are sick. If you want accelerate, then cling to the gas pedal with force, the tachometer arrow crawls up to the point, after which the same turbine begins to blow; A certain amount of time passes, and only then you get a kick in the ass and acceleration, which has started for a very long time. That's exactly what BMW was called by dishonest horsepower.
 
I don’t know if the designers of BMW felt like in the exam, but the journalists who arrived in Austria, first of all, began to check the not famous handling of the Bavarian car, namely, how she reacts to the accelerator. Someone, they say, managed to distinguish between the juicy roar of the in-line six a whistle turbine. As for the dynamics and reaction to gas, I will take the liberty to say that if it were not for the pre -released characteristics of the BMW 335i Coupe motor, very few would have managed to feel that the engine here is turbocharged. And the matter here is not only in the pier-for some, at the sight of the blue-blue propeller, he immediately spirals his breath-the matter in the mechanics.
Excessive horsepower can be squeezed from the engine in several ways. For example, increase its working volume. However, in order to remove the same 306 hp from the motor, which develops 335i, the atmospheric engine should be an eight -cylinder, 4 liters. He would weigh about 70 kg more, which, of course, would affect not only the fuel consumption, but also on the weight of the car. It would be possible to increase the power by increasing the number of revolutions - along this path in Munich and went when they created the BMW M5 - however, this is a technique of a completely different level and, accordingly, a completely different price. Influences and turbine control systems remain. But how to make it work without pauses?
 
First of all, thanks to less inertia, two small turbines create pressure in the system much faster than one large. Open not today and not even on BMW. Nevertheless, each of the turbines blows into three cylinders allotted to it, the engine easily spins up to 7000 rpm, and the maximum moment of 400 nm is already available from 1300 rpm, that is, almost from the start to 5000 rpm. Popying the language of ads - pressed and drove.
 
In the standard configuration on the BMW 335i, a 6-speed manual is installed. With her, the car starts up to hundreds in 5.5 seconds. In order to accelerate in the fifth gear from 80 to 120 km/h only 6.2 seconds. However, 250 km/h on which the electronic limiter is triggered, and the amount of the Austrian fine will be almost 3000, the car is gaining briskly and without noticeable efforts. Thanks to stretched gear, switching is carried out at an optimal speed of rotation, so there is always a power supply under the pedal. The third gear, as usual, looks like an automatic machine - you can go equally comfortably on it and very slowly.
 
An automatic box is available as an option. Moreover, notice, not SMG, but a modified STEPTRONIC. More efficient hydraulics, a new hydrotransformer and software made it possible to achieve not only a faster reaction to the accelerator pedal, but also a quick shift in transmission. According to the designers, compared with previous models equipped with automatic transmission, the reaction time was reduced by about 40 percent, and the gear shift time is almost doubled. Say, from the highest gear after a sharp pressing on the gas, the box switches to the second in a tenth of a second. In addition, the impression of dynamic acceleration is enhanced due to the fact that the hydromoft is connected to the engine directly. You can switch the gears manually - both with a pen and petals behind the steering wheel.
 
The BMW 335i Coupe engine is also obliged to, including its high -precision gasoline injection system, developed by the company's specialists. Piezoforms are located exactly between the valves, so the injector opens out in the form of a cone and evenly distributes it in the combustion chamber. This achieves a more accurate dosing of the mixture and the cooling effect that allows you to establish a higher compression degree, and therefore the effectiveness of fuel combustion.
The Bavarian company has long accustomed us that the coupe is not a limousine with fewer doors, but a very special car. In the profile, this is a central stand shifted back, and the threshold line passing into the front and rear aprons, and the convex arches of the wheels, and the emphasis on the rear axle, which visually emphasizes the rear drive unit. Front, narrower nostrils and headlights of the new design, LED rings in which are also developed for use as daylight. The back lights of the compartment are also a slightly different shape than that of the sedan.
 
Inside is more and more familiar. Unless the color scheme used in the decoration of salons is more fun here. This is not only an emotional excuse - they say, on the compartment we are all cheerful athletes. The low line of the roof and the highly located shoulder line made the area of \u200b\u200bglazing the compartment smaller than that of the sedan. Therefore, such worthy of Negro tuning is available as an option as a luminous tape, passing over the armrests from the door limiter and pouring into the back of the cabin.
 
When you get behind the wheel and stick an electronic key in the panel, a hand that gives you a seat belt leaves from the central rack. The device, very popular in the United States about twenty years ago, is very useful here, because the stand is far beyond the left shoulder, and it would be extremely inconvenient to reach for the belt on your own. Behind - two full -fledged places, the trunk is 430 liters, so you can travel with comfort on the compartment and four.
The tachometer in the top version is marked up to 8000 rpm, and the speedometer - up to 280 km/h. On all other modifications, this is 7500 and 260, although it is clear that the maximum speed is limited by electronics by 250 km/h. Indeed, simultaneously with the BMW 335i Coupe on which we rode, 325i and 330i with a capacity of 218 and 272 hp will appear on the market, respectively, and a little later four -cylinder models. For fans of diesel fans, 330D and 335D coupe are provided. It is curious that if the oil temperature indicator is located in the gasoline versions under the tachometer, then the main place is allocated to the fuel consumption indicator so that the driver feels joy not only from driving, but also because he saves. It cannot be otherwise, because the compartment is a car for an individualist.
