Audi Allroad equipped with low range - additional shift stage itself has no effect on the result, but its activation changes the operation of the EDL system. And well - the result turned out to be exactly the opposite of what was expected. We have our assumptions as to why this happened, but without suggesting anything, we are interested in your opinion 🙂

The results are so strange. The 2.5 TDI version seems to need less engine speed for the EDL/EDS to kick in. This must be a setting that takes into account the greater torque at low revs. However, this setting does not change in the low range, and therefore does not take into account the increase in torque associated with this low range. No hidden ‘Offroad’ mode, either for the EDL/EDS or the ESP...

@@Softroader Docs say that low range changes the EDL setup. And indeed it changes that but not in the way I expected - there's more wheelspin...

@@4x4.tests.on.rollers Perhaps it is. But there's a world of difference between what a textbook says, without being particularly precise, and reality. What does offroad mode mean? More interventions? Earlier? Stronger? Especially when offroad, the ‘optimum’ traction control setting depends on the surface you're riding on, and sometimes too much traction control can be damaging to progress. The development of systems with several selectable modes is not just a question of marketing.

@@Softroader They say: "The EDL in the allroad quattro has also been adapted to accommodate the low range additional shift stage. As the wheel torque is increased by a factor of 1.54 in low range mode, it is desirable to reset the minimum control thresholds. As shown in illustration 241_099, the minimum control thresholds can be very low in low range mode. When cornering, this would lead to undesirable EDL control intervention. EDL control is therefore suppressed when cornering is detected (via the ESP input values). The function is automatic when the additional shift stage has been actuated." The only clear thing from the graph is that EDL should intervene at lower speed difference between the wheels.

Pretty disappointing. I expected a much bigger difference but it seems the system still needs an excessive amount of wheelspin to do anything...

Very disappointing results. That 2.5 was my dream car when I was younger. Now as an old guy I bought a V90 Cross Country D5 and I am very glad I did. With vredestein quatrac pro tyres it is managing snow, ice and mud very well.

To może jeszcze jakaś zrzutka na tylne amortyzatory do wersji manualnej? Bo tak przecież nie można go puścić na drogi publiczne, a przy tym zawieszeniu pewnie nie są zbyt tanie...

Znam dużo osób które kupiły allroada bo były tanie i miały napęd na 4 koła Ale płacz zaczynał się przy serwisowaniu i kończyło się na sprzedaży w czasie krótszym niż rok Amortyzatory tylne z pdc to koszt ok 3000 zł szt za oryginał I ok 1600 za zamiennik

Pretty strange result, not entirely sure what the Audi engineers and marketing people were thinking when they stole the term low range from the off-road world. What do you think this system actually does?

@4x4.tests.on.rollers 4 күн бұрын

@@CanadaLuke Low range itself has 1.54 ratio but it's not the point. The point is that it engages different EDL operation.

Thats pretty damn sad performance, somehow the center diff has sooo much slip you have yo floor it to make enough torque to get over the rollers Do you have a crane type scale? I would love to know the draw force required to pull a car off one or more rollers, can you push an average car on or off them with just people?

Kultura pracy tego diesla jest niższa jak chama ze stachetą w ręku pod remizą w Piździwólce Dolnej hahaha i ten tyłek wesoło skaczący. Aż dziw że 4x4 w tym szrocie działa. Ale spokojnie nie za długo, z takim dbaniem i to zaraz padnie. Nie chodzi mi tu a bezmyślny hejt ale wypadało by robić porównania na "względnie" zdrowych egzemplarzach a nie na zajechanych rupieciach kolego. Pozdrawiam.

@@AntekWyrwidomb Zwracam uwagę, że mamy tu dwa egzemplarze i jakoś specjalnej różnicy w działaniu napędów nie widać. Rzekłbym nawet, że w TDI działa lepiej. A wesoło skaczące tyłki zdarzały się i w nowych samochodach, w tym teście niczego to nie zmienia, podobnie jak i dźwięk silnika. Torsen pochodzi raczej z gatunku pancernych, czepiać można się sprawności hamulców - tego zweryfikować nie możemy.

@4x4.tests.on.rollers ja nie chcę być tym toksycznym człowiek co się czepia wszystkiego, i nic nie daje od siebie, ale po tym co widziałem na filmie wątpię w zasadność testów na tych egzemplarzach z racji ich dużego zużycia i prawdopodobnego działa nieprawidłowego. Nie chodzi o metodykę testów, to co chciałem zrobić i pokazać zrobiłeś moim, nie fachowym okiem dobrze, ale auta które były wykorzystywane w teście, zwłaszcza diesel to gruz zwykły. Ta benzyna wydaje się spoko, ale brak różnic w wynikach skłania mnie do wniosku że oba są tak samo zużyte i nie działają prawidłowo. Prawdopodobnie. Pozdrawiam.
