The maximum speed of many vehicles or factory of manufacturers by an electronic lock. a software lock limited.
This means, the vehicles could go faster, however, from a fixed rate abgeregelt.Eine such throttling the speed or. Maximum lead e.g.. Manufacturers such as Audi, Bmw, Mercedes, Porsche etc. by.
the so-called 250 km / h limit is known of these limitations VMax. More power cutbacks or. Limitations are found e.g.. at 280 km / h or 300 km / h.
The following table shows some models with limit, where a VMax cancellation is possible:
| model | VMax |
| Audi A8 / S8 4H Series | 250 / 305 km / h |
| Audi S3 / RS3 8V | 250 km / h |
| Audi TT (TTS / TTRS) 8S | 250 km / h |
| Mercedes Benz C-Class AMG 205 model series (C43 AMG / C63 AMG / C63S AMG) – only the Vorfacelift model | 250 km / h |
| Mercedes Benz GLC-Class AMG 253 model series (GLC43 AMG / GLC63 AMG / GLC63S AMG) – only the Vorfacelift model | 250 km / h |
| Seat Leon (Cupra) series 5F | 250 – 260 km / h |
| VW Golf 7R | 250 km / h |
And here are some impressions of the above models:
Origins of the maximum speed limit
Often, the VMax lock is used in high-performance models such as the Audi RS, BMW M models and the Mercedes AMG.
reason 1: Profitmaximierung
However, these can be removed at an extra charge by manufacturers. However, this VMax waiver in the form of so-called "Drivers Packages" can be the manufacturers pay well.
But "normal" models are down regulated at this speed, although the motor may enable a higher speed.
This is because, that in the meantime the same engines are installed in different models (so-called equal parts strategy), due to cost savings in production.
However, in order to distinguish the models from each other,, among others, the VMax locks are inserted, as well as other functions via software limits / disabled. (Here be worth incidentally vehicle codes)
But other providers do this in less powerful models, to distinguish them from one another even further.
This allows different models in spite of the same engine in different performance versions are offered. So manufacturers achieve profit maximization by the speed-limit.
Apart from that also have car rental and leasing vehicles limits, and some vans and SUVs, or even a smart!
Even in imported cars such as e.g.. from the USA can be found at a boundary 200-215 km / h. However, this has more legal grounds, da z.B. on American roads a maximum speed is set.
reason 2: Political
Another reason, why there is this VMax limit at all, is adjacent to the monetary aspect as well as to distinguish the models, also a political background:
In the 80s, there was the so-called "gentlemen's agreement" the European car industry. This agreement said, that vehicle manufacturers voluntarily in their cars an electronic speed limit 250 / Integrate km h.
This decision was politically motivated and represented a concession for politics. Because in the 70 years, a debate about the oil crisis and fuel consumption has developed. In addition, also there was a discussion about the safety on European motorways.
With the self-imposed decision, the manufacturers wanted their object, that the issue does not continue "aufkochte" - And with success, as you can see. Even today there are in Germany no general speed limit or. no maximum speed limit on the highways.
The solution: VMax repeal – but how?
To cancel the factory boundary there are different ways.
So you can lock via the vehicle coding remove. In this case, the map of the vehicle is optimized, that the speed is no longer limited.
However, not is a Power enhancement by Chiptuning , as one might think, but only a reprogramming of values of the existing software in the engine control unit.
An increase in engine power is separately possible, However, this should be closely watched, whether engine, Brakes and tires support this increased output.
However, this variant may affect the warranty of the vehicle. A programming must be made namely again Undo. This is only possible, if the original software is accessible or a backup was performed by the chip tuner.
Another way is the use of a module.
- The benefits of VMax Nullification modules are, that these are cheaper than the original package („Drivers Package“) the manufacturer.
- The modules are deinstallation. virtually e.g.. for leasing cars. Advantage over OBD (On-Board-Diagnose).
- Guarantee preservation is rather given by modules, since there is no interference with the Motorsteurgerät takes place.
If you are interested, we at Cete Automotive can code a VMax cancellation via OBD interface, or I looked at you once our new module VMax repeal an: the Active VMax Deleter .
