Which one is faster with manual gear vs automatic gear? ?
　 Focus RS vs A45 A MG vs Golf R Drag Race This is a straight-line acceleration pk shot by “Topgearâ€. Please automatically shield the Mercedes-Benz A45 AMG from the dust, and focus on the very close 7th Generation Golf R and 3rd Generation Fox RS. The 2.0T of the Golf R is equipped with a power level of 295 PF/380 Nm. The Fox RS 2.3T engine can output 345 PF/440 Nm. The RS engine also has an overboost function that lasts for 18 seconds, so it can actually output 470 Newton peak torque throughout the sprint. In the video, the golf R trimming quality is 1495kg, while the Fox RS is 1599kg, so the golf thrust ratio is 197.3 mpg/ton while the Fox is 215.8 mpg/ton. Both vehicles use four-wheel-drive systems, gearboxes are all six stops, and are equipped with ejection mode. So they are indeed textbooks that measure the efficiency of transmissions. As a result, everyone saw that the less powerful Golf R defeated the Fox RS. The host said he lost the gear, and every time he stepped on the clutch and hung up to the next gear, he felt himself thrown away by the golf ball. The video does not explain what the length of the drag is, but the clip shows that the Fox RS hung in front of the line 4 blocks, that is, from the start to the red line host to change the third block. In general, a good rider can complete a manual shift in about 0.5 seconds, and the official DSG data given by Volkswagen is about 200 milliseconds. We assume that each time this host uses 0.5 seconds for each shift, RS will use 0.9 seconds more than high R after 3 shifts. From the comparison of the two figures below, you can intuitively see that the manual shift will lose a large amount of time in continuous acceleration. Golf R DSGGolf R DSG MEGANE RS MTMEGANE RS MT So the conclusion is very clear, in the use of such a drag race environment, excellent automatic transmission will be far faster than the manual transmission, which is not controversial. But the question is, how many people have the opportunity to start using Launch Control in daily driving? To activate this function in most vehicles requires a series of complicated operations. Usually you have to choose the most sporty driving mode, set the ESP to sport or simply turn it off, and some cars require you to make step-by-step options in the menu. After all this has been done, all the ejection modes will eventually require the following operations: 1. Put all the throttle and brakes in the end, 2. Wait for the speed to stabilize 3. Do not release the throttle while quickly lifting the brakes. I doubt that many people will actually use LC mode on the road even if they suddenly encounter the unreasonable provocations of other vehicles. So what's the difference if you don't shoot it? The answer is the starting speed. Any automatic transmission cannot start at a higher speed in the normal driving mode (usually no more than 2500 rpm). This is mainly to prevent the complete transmission system including the transmission from being premature. There is strain. So no matter how powerful the engine of your car is, you will always feel powerless at the moment you start. The following is an acceleration curve for the 0-400 sprint when the C63S is unable to use the LC mode. Mercedes Benz C63 SMercedes Benz C63 S You can see that this curve is basically a watershed with a speed of 100km/h. In the 0-100 range, the acceleration curve shows an upward trend, which means that as the vehicle speed increases, it accelerates faster and faster, and when it exceeds 100, the acceleration curve reverses downwards, that is, the acceleration gradually slows down. This curve shows that the partial acceleration of the C63 S was lost during the period from the start of acceleration to 100 km/h. Because under normal circumstances even a car with ultra-high performance after passing through a very short-term non-linear region (usually at 0-30km/h, this is mainly due to the grip caused by the centrifugal force of the tire due to the violent acceleration rotation) Loss of ground force, and the resultant result of the electronic system attempting to help the wheel recover grip, the entire acceleration curve should slow down linearly. The C63 S did not do this because the starting speed was not enough, so it was impossible to use the maximum power of the engine from the start. How much damage does this cause? The answer is close to 1 second. The official 0-100 acceleration time announced by the C63 S is 4 seconds. The best result when starting without the LC feature was 4.95 seconds. Vehicles that use manual transmissions do not have a limited start-up speed regardless of their LC function. The speed at which you want to start after pressing the clutch depends only on the amount of force applied to your right foot. The key to getting agile as quickly as possible is nothing more than making the engine's speed match the wheel's grip, and it's not difficult for everyone to master this after any exploration in any one car. Once you have found this speed point, you can avoid the ESP jumping out to find you in a very agile start. In a real driving environment, this superior performance allows you to become significantly more powerful in the fight. Another situation that would make a sharp contrast between the performance of the two transmissions is a sudden downshift to accelerate the overtaking in uniform travel. For example, if you drive a manual car with a 6-speed superb ride at 65 km/h, then there is an SUV that is significantly slower than you, when you make a decision to pass the car. You can complete the shift in advance. As for the 6th speed to 3rd speed, or 5th speed to 2th speed, you need to use a clutch action at a slow speed. You don't need to perform a sequence downshift like on the track. You can hang in the gear you want, and then give the oil - change line - take you - get it. In the entire overtaking process, the vehicle's speed is controlled 100%. Because the shift has been completed, the speed increase only needs to rely on the throttle to complete, the driver can freely control the timing of starting speed, the speed of speed increase, and the required maximum speed. If the overtaking process requires an upshift, the driver can also determine the shift speed. In the same situation, if you are using an automatic transmission, it is not so simple. Usually when you decide to overtake, what you will do first is to step on the gas pedal. Then you need to wait. The gearbox cannot be synchronised. It takes time to predict whether there is a need to lower the gear or need to lower a few gears to meet the depth of the throttle. Driver's acceleration needs. The pre-determined time required for automatic transmissions of different forms and grades varies greatly, and a significant delay sometimes makes it very urgent or impossible to make an overtaking that was otherwise very easy. Even a very good automatic transmission driver will need to spend more effort to control the throttle when overtaking, because in this case the throttle opening determines both the efforts of the engine work will also affect the transmission file Bit selection ------ Not only does it end up in a few stops, but it also depends on the driver's control of the throttle. Suspended into the S-block (automatic gearbox motion mode) does make the gearbox more willing to stay in the low gear, which objectively helps the vehicle get a more agile speed response, but the automatic gearbox requires super A high shift speed, if the entire overtaking process requires at least one upshift, and the objective conditions (such as the width of the road, the field of vision) make the driver unable to use the full throttle, the situation will become a bit embarrassing. Of course, many people will say they can cut into manual mode. If your car is equipped with a steering wheel dial, then it is not difficult to lower the gear, but the paddle shifter only accepts the sequence shift, that is to say if you want to enter the 2nd gear in the 6th gear, then only press the 4th paddle to do it. To. If your car is not equipped with a paddle, the situation will become even more troublesome. You need to push the shift lever into the manual mode and then repeat it to use the gear you want. The fundamental difference between manual transmissions and automatic transmissions in actual use is that the driver can directly dispatch the former, while the latter's operation is subject to the computer. The automatic transmission can only “estimate†the driver’s intentions based on the signals provided by the sensors, even with technology. The progress of the "Quality Quotient" of various automatic transmissions has been continuously improved, but at present, the automatic transmission still cannot provide the intuitiveness comparable to a manual transmission. So back to the original question in this article, which is faster, automatic and manual? Obviously, if you only care about accelerating or the lap speed on the track, there are countless comparison videos on Youku and Tudou that proves that the double clutch with shifting speed in milliseconds has an absolute chance of winning. But back in a complex everyday driving environment, manual transmissions have in many cases even the most advanced automatic transmissions in the world have unmatched stress. So the next time you need to choose between automatic and manual, if "convenience" is not a decisive appeal, perhaps you should consider whether you should easily give up the clutch pedal. transmission.
