The truth is that the car is gaining 100 km per hour for a certain number of seconds. And everything is measured differently, but the value issued by the manufacturer is close to real.

13.08.2009, 15:31

i think every manufacturer is interested in smaller seconds
People like it
Accordingly, the measurements should tear and throw all honest and dishonest ways.

Then it is not known that m3 under the hood, there can be trees there already with another lifting, etc. etc...
Well, dotnika dick ... It happens that the cars are tired, the box does not have time to adapt ....

All manufacturers measure acceleration to 100, but not a fig that they do it? Auto in the regular mode starts at the same time or tear with revolutions?

Think about forced races with Mazda 3 ...

In seconds, the moment and horses come out that there are 400 meters check-in without options for pichenium 35, but in fact not everything is so simple ...
At the start I drague, because Mazda on the handle and tears with turns and with slipping ... then in the course of nuts, but there is not enough time to get around ... :(
Somehow bench press itself with the turns. Started several times, but turns around 2-3 thousand were only

I understand about the gasket, but I thought that on TXH machines was supposed to tear ...

PS: This Mazda climbed with the BMW 330 coupe, Beha, the automotive start merged (from idle), but then bypassed without options ... Where is the truth?

Well, firstly, the figure is 7.1 IMHO, erroneous. They are taken, so I think, from the catalog Auto.ru, and there is a lot of mistakes.
Somewhere I saw, the figure of 7.6 flashed, and not the fact that not up to 96 km / h (60 mph)

Secondly ... It was today that he drove to the E46 330 touring. If I'm not mistaken, he has a passport acceleration - 7.2 sec.
They started with idle, up to 100-120 is absolutely the same, then it takes a little bit and lose a bit less than the body.

In general, confessions, sick to arrival? :)

14.08.2009, 10:37

in the arrival of 400 meters, speed is higher than 100 km. And at speeds 150-160 already flowing plays a big role \u003d)))))
I will slowly catch it at all distances, i.e. and at speed more than 100,
In addition, a telemetry pharyn in the next topic on the finish only 150 gains

In general, confessions, sick to arrival?
In principle, yes, I often squeeze ...

PS. Perhaps specifically with your car something wrong.
There is a video of the terrible quality of overclocking up to 100 with idle ...
The storyboard shows the following:
The tachometer arrow starts, about a second starts the speedometer arrow, a hundred speedometer shows 7 seconds after start, while the gas pressure and up to 100 on the speedometer, roughly speaking, 8 seconds
I think it approximately stacked in the claimed TXH
more accurate result only telemetry will give

14.08.2009, 21:09

in principle, yes, I often squeeze ...
I had the idea that the brains are adaptive and adjusted for my driving manner. Like the disconnection of the battery this should be treated?

No! It is not necessary to do so exactly !!!: EEK:
It is treated with an aggressive ride :)


On the mechanics rode or in D?

Air conditioning turned off?
VDS turned off? (Although when they are driving mine no difference)
Plus more gasoline affects ...
Maybe Mazda is not stock ...

If you start on the handle from 2000 revolutions, then I must bring 2-3 Mazda buildings. (I repel from the results of the races of Mazdi against Skoda Octavia 1.8 turbo 150 hp)

Last week, a man on Mazda CX7 was very confident in the victory against my dick. Only there was 400 meters without options for him. After the arrival was told for a long time that in the city of different FX35 broke the pieces six ... already swung on FX45: D
In general, we were talking about the maximum speed - I was 100% sure that it was easy and easy to go around him and in this discipline))) I went to the track and I turned out to be a mistake - absolutely smooth maximum speed (I have a little more than 230 on the speedometer) in two races are equally.
It turned out to be an American and no limiter ...
Agreed to repeat the arrival from the place for tomorrow, because he complained about gasoline, but this will not save him: D

15.08.2009, 11:19

Stoke Mazda 3 - I am confident by 99% what's swaying it
What is it like??? How do you ride something?

And box how? Sneaker to Paul pressed to arrival?

15.08.2009, 15:03

17.08.2009, 10:52

It is treated by aggressive ride
Personally, I do not see the difference (refers to the manual mode) I can nauseate for a long time, then if you need to switch to manual mode and the machine is perfectly rides and does not tupit ..
How many times do you need to aggressively start, so that the brains understand what aggression needs? It seems to me 2-3 times will not help, the brain will think the fluctuation ...;)

Stoke Mazda 3 - I am confident by 99% what's swaying it
In general, there are many nuances here, so to speak ...
On the mechanics rode or in D?
If on the mechanics, at what revolutions switched and the cut-off did not catch?
Air conditioning turned off?
VDS turned off? (Although when they are driving mine no difference)
Plus more gasoline affects ...
Maybe Mazda is not stock ...
All turned off, and radio incl.
I did not notice the difference from VDC, I'm not grinding at the start
benz ... 95th, there is an opinion that benz happens better, but not we
The last time I had a floor of the tank, I don't know how much (however, I see no sense for victory on the light bulb)

I tried in D, and in manual, there is practically no difference
On D C 1 to 2 Switching goes to 6000 (on video), from 2 to 3 to 6500 ...
in manual all switching to 6500, cut off did not catch
4th not counting

In general, the date is really going a little faster, always slowly cattons
But all spoils start, i.e. No jump on the start ...

Do you look at before buying? What do you first pay attention to? Of course, most of us after the cost of the car are interested in the dynamics of the acceleration of the machine and its fuel consumption. But did you think about the measurements of the car dynamics occur when overclocking from 0 to 100 km / h? What do you think the figures specified in the technical specification on the car are real? Let's deal with.

Each automaker, before running a car in a series, conducts many different tests, with the help of which checks it on reliability, quality and safety. In case of identifying some problems, engineers make changes to the machine device. Next, before the very serial production, cars are tested to compile technical characteristics. Of course, presented the greatest interest, which measure the fuel consumption of a car in urban mode and when driving along the highway.

Then the manufacturer calculates the average. Also for the full data of the technical specification, each car passes tests that determine the dynamics of the machine during acceleration from 0-100 km / h. In some cases, for example for sports cars, cars run tests at speeds 0-200 km / h and even 0-300 km / h.

How is the car dynamics determined, and how is it related to fuel consumption?

As a rule, the dynamics of acceleration in most cases determines the automaker during special tests. Typically, the test for the acceleration rate passes on a special dynamic highway. During this test, the test car passes a certain distance, accelerating to 100 km / h. First, the movement is carried out in one direction, then to another.

Naturally, depends on the class of the car, and the engine power. Not the last role is played and the type of gearbox that transmits torque on the wheels. Also on the speed of overclocking the car influence the aerodynamic characteristics of the body.

So, the engine power primarily affects the maximum torque (power). And, as a rule, the greater the power of the motor, the higher it is torque. Thus, cars with more powerful engines are more dynamic.

By the way, the type of engine does not usually affect the overclocking dynamics. That is, no matter what engine is under the hood of your car - diesel or gasoline. If the motor has a big power, then the car will be more dynamic.

As regards the gearbox, it was used to be that a manual transmission faster automatically transmits torque from the engine to the wheels. Accordingly, the cars with the manual transmission accelerated faster.

Today it is impossible to argue. The fact is that modern automatic or semi-automatic transmissions are complex electronic devices managed by a computer, which by reaction is significantly ahead of the response of even a professional driver. That is, modern automatic transmission switches the transmissions faster than a person. Consequently, many new automatic transmissions are ahead of switching gears in mechanical boxes.

The fastest acceleration by cars, as a rule, are sports cars and various luxury sedans and SUVs, which are often completed with the latest powerful motors and complex gearboxes. Basically in such cars, the power of the engines begins from 200 liters. from.

A special class of cars with powerful engines begins with a capacity of 250 liters. from. True, cars with such power are subject to a considerable taxation. For example, the vehicle tax rate is more than 250 liters. from. The highest in the country. But, as a rule, those who can afford to buy a car with a capacity of 250 liters. with., does not particularly worry the transport tax rate. After all, only wealthy drivers can buy a powerful luxury car.


Most cars with a capacity of more than 250 liters. from. Have the dynamics of overclocking from 0-100 km / h on average from 4 to 7 seconds. which accelerate faster than 4 seconds, have very big power and cost huge money. In this range of acceleration, one premium sports cars are presented mainly.

As for the dynamics of overclocking ordinary cars, which are massively used by most motorists, then on average, such cars accelerates up to 100 km / h around 9 to 11 seconds. In seconds, this is a small difference, if you compare with more expensive premium cars. But on the road it is a huge difference. Although for the average movement in the city of overclocking dynamics in 10 seconds is quite enough. More and no need.

What about minivans and SUVs? What acceleration of this type of cars? Most SUVs and minivans do not differ any particularly fast dynamics. In general, real inexpensive SUVs and minivans acceleration is quite calm. The average overclocking range to "hundreds" - 11-13 seconds. But this class of cars is quite enough, because they are intended for a leisurely drive in the city. For SUVs, the dynamics of overclocking is important, and the possibilities for off-road, according to which it is often necessary to move at low speed.

Is it true that the cost of servicing powerful cars is more expensive?


Yes this is true. Most powerful machines cost owners much more expensive than less powerful cars. The thing is that more powerful cars are equipped with more complex engines in design. Also more powerful machines are equipped with a more complex brake system, enhanced suspension, more expensive wheels and rubber.

And most importantly, most powerful cars require more perfect, expensive engine oil. And the worst thing is that on more expensive powerful cars, maintenance is recommended to take place more often than on ordinary modern cars.

How does the dynamics of acceleration affect fuel consumption?

As a rule, in the main time we do not push the gas pedal to the floor, in order to move from the place from the traffic light. But if you need to accelerate from a place for the minimum amount of time, it is necessary to press with a greater force on. In this case, the car will start accelerate more dynamic. But, as they say, in life for everything you need to pay. Remember that with the maximum possible for your machine, the dynamics of overclocking you pay the ruble. No, no, we are not about fines for speeding. We are talking about fuel consumption, which grows almost 2 times with quick acceleration from the scene.

The most interesting thing is that manufacturers in their technical specifications try not to indicate fuel consumption during the dynamic acceleration of the car from 0-100 km / h, hiding this indicator with its usual fuel consumption specifications in the city, on the highway and in a mixed cycle.

How does the dynamics of acceleration of the car affect security?


Oddly enough, the dynamics of the acceleration of the car directly affects safety. Do you know why? The thing is that very often there are accidents on the road due to the fact that some kind of car did not have time to complete the maneuver. But why many drivers do not have time to complete the maneuver on the road? For example, overtaking. Just the reason - in the dynamics of acceleration of the car. Just many drivers at the time of the beginning of the overtaking often mistakenly believe that they will have time to complete it, but as a result, their self-confidence plays an evil joke.

Yes, the rapid dynamics of overclocking in the modern world is not required. Especially in the city. But the more powerful and more dynamic than the car, the less the risks of the accident due to maneuvers on the road. Especially when overtaking.

By the way, in the modern world most automakers offer us a wider choice of cars. Today you can choose the same model, but with different motors. Naturally, the smaller the power of the motor, the cheaper the car will cost. That is, these days, manufacturers offer us the same models for different purse size and different preferences of motorists.

So when buying a car, think that you are more important: efficiency or power. After all, the smaller the power of the car, the less it will consume fuel. But for this you pay off the dynamics of overclocking. We advise you when choosing a car, take into account your driving style. If you prefer a more dynamic vehicle management style, we advise you to take a car helper. If the dynamics of acceleration from 0 to 100 km / h is unimportant and for you the most important auto indicator is the fuel consumption, then buy a car with a weaker motor. It will not only cost you cheaper, but will save money when servicing and when refilling on.

Acceleration up to 100 km / h in ten seconds - slowly? How to say. Compared to supercars that exchange "hundreds" in four to five seconds, this result, of course, is not impressed. But here is another landmark: Hyundai Solaris Even in the fastest version with the engine 1.6 and "mechanics" accelerates to 100 km / h in 10.3 s. But these machines tend to drive the overall flow. In addition, the new "ten-secret" car can be bought at a completely imputed price.

With an amoe available offer - sedan (1.6 liters, 114 hp), which accelerates up to 100 km / h for 9.5 s and costs 610 thousand rubles. Hatchback Kalina Sport With the same characteristics, a little more expensive (617 thousand), and both cars have air conditioning, a media system, parking sensors and other useful options. True, our tests are more powerful for 850 thousand rubles - forced motor 1.6 (136 hp), a modified gearbox and a steering mechanism, anterior suspension on a separate subframe, Renault brakes, self-locking differential - when passporting 9.2 s showed everything 10 s.

Volkswagen Polo Gt.

Sedan Volkswagen Polo. With a turbo engine 1.4 TSI (125 hp) exactly faster than the way: 9 s on a passport, but 9.2 s at the machine with "mechanics" and 9.4 s - with a "robot" DSG. Prices begin with 794 thousand rubles, and a two-week version costs 864 thousand. This Polo is well suited for daily use, the chassis is almost no different from the basic version. Related Liftbek Skoda Rapid 1.4 TSI (125 hp) is only with a "robot", reaches 100 km / h for the same 9 s (9.5 ° C) and worth a minimum of 915 thousand rubles. Of the advantages - the practical body of Liftbek, of minuses - a rigid suspension.

To powerful cars of class C + without a million not to come. Even PEUGEOT 408. With a 1.6 THP turbo engine (150 hp) and "automatic", which by passport runs "hundred" for 9.6 s (10.1 s), taking into account the branded discount costs 997 thousand rubles. His relative Citroen C4. It should accelerate up to 100 km / h for 8.1 s, but it turned out for a second and a half longer, and the prices - from 1 million 168 thousand.

Skoda Octavia. Nizhny Novgorod assembly with a turbo engine 1.4 TSI (150 hp) and "mechanics", according to factory data, can develop 100 km / h in just 8.1 s, and with a "robot" DSG - after 8.2 s. Spacious interior, honed chassis, although the smoothness of the stroke is not the best. Formally, prices begin with 998 thousand, but for a car with fitting equipment you need to give at least 1.2 million rubles. Octavia 1.8 TSI (180 hp) Slightly more expensive: approximately 1.3 million rubles for elefbecks with a set of primary options, and overclocking up to 100 km / h - for 7.3-7.4 c depending on the gearbox. Moreover, the richest choice of tuning kits will make Oktavia even faster! There are also universals that are inferior to liftbacks of only 0.1 s in acceleration to "hundreds", but they come from the Czech Republic and therefore more than 320 thousand rubles.

Sedan Volkswagen Jetta. 1.4 TSI (125 hp) is more comfortable, but slower Octavia: 9.8 s according to the passport, and the version with the "robot" showed 10.6 s. At the same time, Jetta is also more expensive: minimum 1 million 145 thousand rubles. And a rare modification with a two-trunk version of the 1.4 TSI motor (150 hp, 8.6 s) and at least 1 million 309 thousand rubles are at all.

Another option - sedan Kia Cerato. 2.0 (150 hp): With an "machine" announced the time of overclocking 9.3 s, although it turned out 9.9 s. Prices are attractive - from 1 million 90 thousand rubles. Sedan Hyundai Elantra. 2.0 (150 hp) slower: 10.5 s at a car with a "automatic" instead of passports 9.9 s. Although the arsenal also has a version with "mechanics" with the claimed time of 8.8 s. Powerful elantra are only in expensive equipment, therefore it is worth a minimum of 1 million 165 thousand rubles.

Ford Focus 1.5 EcoBoost (150 hp) may not only be a sedan, but also a hatchback or wagon. When passported 9.2 with overclocking, the hatchback showed 9.4 s. The sedan and the wagon must be slower than 0.1 and 0.2 C, respectively. In addition, Focus can boast excellent handling, but machines with turbomobiles are offered only in expensive equipment at a price of 1 million 181 thousand rubles.

Mini Cooper.? Turbotroom 1.5 (136 hp) is able to overclock the machine with a "automatic" to 100 km / h, although the passport details are 7.8-7.9 C depending on the gearbox. The chassis is configured in combat, but prices bite: at least 1 million 189 thousand rubles for a naked three-year with "mechanics", and for the version with the "automatic", climate control and other status options are already preparing 1.4 million rubles. Five-door versions are more expensive for 30 thousand, and prices for a more severe universal Mini Cooper Clubman (passports 9.1 s to 100 km / h) are just beginning with 1 million 349 thousand rubles.

The most affordable car with a motor capacity of more than 200 "horses" - three-time Kia Pro_cee'd GT. (1.6 liters, 204 hp), but with such a "charge" overclocking up to 100 km / h for not impressive (7.6 seconds are promised according to the passport). The gearbox is only mechanical, chassis without pepper, but for daily use such a hatchback fit well. Yes, and the price is sane - 1 million 225 thousand rubles, and richer equipped with five-year Kia Cee'd GT. It will cost 1 million 315 thousand. Hatchback Kia Soul. GT. With the same engine and "robot" a little slower (7.8 C according to the company) and costs 1 million 370 thousand.

Kia Pro_cee'd GT.

For 1 million 350 thousand rubles are offered tiny smart Brabus Fortwo. With a 900-cubic turbo capacity of 109 hp Pocket rocket? Alas, because of the configuration "Robot", even the factory data promise acceleration to 100 km / h for 9.5 s, and the long-beed Brabus Forfour is slower for a whole second.

Within one and a half million you can pick up relatively dynamic business class car. Although passports 9.6 s in a 150-strong sedan Kia Optima. 2.0 with "mechanics" (1 million 160 thousand rubles) is hard to believe. A version with a motor 2.4 (188 hp) and "automat" promises overclocking for 9.1 s, but worth not less than 1 million 480 thousand. Skoda Superb. 1.4 TSI (125 hp) with mechanics for 1.3 million rubles should be accelerated for 9.9 s, and a 150-strong version with a "robot" - for 8.8 s, however, such a liftbek is even without options 1 million 434 thousand rubles. In addition, for 1 million 495 thousand offered Mazda 6. With a motor 2.5 (192 hp) and passport acceleration to 100 km / h for 7.8 s, although they showed 8.9 s.

Judging by the company data, in agreed price framework, there are also "decheconden" crossovers. For example, front-wheel drive Nissan Qashqai. 2.0 (144 hp, 1.27 million rubles) and Skoda Yeti. 1.4 TSI (125 hp, 1.22 million) with mechanical transmissions accelerate for 9.9 s. Mazda CX-5 2.0 (150 hp, 1.37 million) Depending on the transmission, it makes it for 8.9-9.4 s, and all-wheel drive Skoda Yeti 1.8 TSI (152 hp, 1.39 million) - for 9 from. But the time is so Skoda - 10.1 s.

If you sacrifice options or persuade a dealer for a good discount, you can count on the hatchback Volvo V40 Cross Country T3 (152 hp, from 1.47 million) with "automatic" and overclocking time 8.5 s. Or at BMW 118i (136 hp, from 1.49 million), which, depending on the gearbox reaches "hundreds" for 8.5-8.7 s. Well, if you need a car leaving from 7 s, then prepare at least one and a half million Mini Cooper S. (192 hp), which according to the passport accelerates for 6.7-6.8 s.

* Overclocking time up to 100 km / h by measurement measurements

by the way, there is a method for measuring the high-speed properties of the PBX according to GOST. So, for reflection ...

GOST 22576-90.

State Standard of the SSR Union

Motor vehicles.

High-speed properties

Test methods

GOST 22576-90.

(ST SEV 6893-89)

2.1.1. PBX, intended for testing, must be a good, commissioned, fastened fuel in accordance with the regulatory and technical documentation. The engine, transmission and tires must undergo proper run in accordance with the manufacturer's instructions and have mileage, including running, at least 3000 km.

2.1.2. Tire wear on PBX should not exceed 50%.

Tires should not have damage. Tire pressure must meet the manufacturer's requirements.

Pressure is measured and regulated on "cold" tires. In the process of testing PBX, pressure regulation is not allowed.

2.2. Massage of cargo

2.2.1. When testing should be applied:

full weight of cargo - for PBX with a complete mass of over 3.5 tons;

half of the mass of cargo, but not less than 180 kg - for PBX with a full weight of up to 3.5 tons inclusive.

2.3.1. Measurements are carried out on a solid smooth clean and dry road section with good clutch.

2.5.1. During road testing, the PBXs must comply with the following requirements. The average wind speed, measured at a height of 1 m above the surface of the road, not more than 3 m / s (with gusts up to 5 m / s). The air density should not differ by more than 7.5% of the density of air defined under normal atmospheric conditions (atmospheric pressure P0 \u003d 1000 GPa (750 mm Hg. Art.). Air temperature T0 \u003d 293 K (20 ° C).

3.2.1. Determination of the maximum speed on the direct portion of the road when driving in two directions

The maximum speed is determined on the transmission, which ensures the achievement of the greatest steady speed of movement, which is installed before entering the measuring site.

The fuel supply pedal must be pressed until it stops. The number of measurements (races) is at least three in each direction. Changing the speed in the arrival should not exceed 2%. Each arrival should determine the time of passing the measuring site. The difference between the extreme values \u200b\u200bof six dimensions should not exceed 3%.

3.2.2. Determination of the maximum speed on the direct portion of the road when moving in one direction

The determination of the maximum speed when moving in one direction is allowed only if the characteristic of the road does not allow to achieve maximum speed in both directions, the additional conditions must be observed:

the change in the height of the longitudinal profile throughout the horizontal measuring site should not exceed 1 m;

the axial component of the wind speed should not exceed 2 m / s.

The measuring site is passing five times; Cutters must follow directly one by one, while the time of each check-in is measured.

3.4. Determination of overclocking time to a given speed (Indicator 1.3)

3.4.1. The acceleration time to a given speed is determined as an average arithmetic value according to the results of races made in accordance with paragraph 3.3, or by the curve of the dispersion mode of the PBX from the place.

The following values \u200b\u200bof the ending speed of overclocking are set:

100 km / h - for the PBX of all types with a complete weight of up to 3.5 tons;

80 km / h - for trucks, buses (except urban) with a complete mass of over 3.5 tons and road trains.

60 km / h - for city buses.
