Diskuse: CLK DTM AMG: další supersportovní Mercedes-Benz

sen zvedav co jeste vytunej,mohli by to strcit co C-klady :)

noch frage??

takovyhle typky mam rad, kritizuji vsechno co je novy a dobry
a v garazi jim stoji 120, tem lepsim rezavej favorit!

to je špičkova mašinka,prostě Mercedes!

Škaredý jsi ty a neto auto!!!

Noch ein Quentchen fixer geht die Version mit dem Mercedes-V12-Biturbomotor zu Werke. 3,4 Sekunden für den Sprint auf 100 km/h und eine Höchstgeschwindigkeit von 350 km/h verspricht Laraki für den 6,2-Liter großen V12-Motor mit einer Leistung von 660 PS und einem maximalen Drehmoment von 1.300 Nm.

to je prostě vrchol automobilového techniky

přesně na český kvalitní silnice ::)) chudák auto.

Co to meles?? Jaka absolutni spicka??
5,5 l V8 navic jeste s preplnovanim a pouhych cca 575 k? No to je prumer, u zavodaku podprumer! Vzdyt jenom Mnichov je o par desitek koni pod a to nepreplnuje. A k tomu prihodej 5!!!stupnovej automat. To nemysli vazne!
A navic, tohle neni ani na silnici, to u MB pracuje vychytraly marketing. Prodavaj, co se da. Dost mozna vypusti homologovanou F1. Snad jim to nebude litat vzduchem jako pred par rokama v LeMans
MB si totiz dela svoji vlastni spatnou definici sportovniho auta. A vy tomu rikate, ze nema konkurenci. Jsou to rychle cestovni sedany s vynikajici pruznosti. Ovsem pro ty, kdo neznaji pojem razeni. Preplnovani neva, ale v tak velkem objemu? Napadaj me ve stejne kategorii uz jenom nakladaky. Prevodovka? At tomu nerikaj sportovni auto, probuh!!
Libi se mi jak se predhanite ve vypisovani udaju. V12, NM pres 1000, hmm. Chybi Vam neco, kluci? I s malym kasparkem se da totiz zahrat velky divadlo Staci malej vytocenej japoncik s turbickem. I malej psik utece nejlepsimu nadopovanymu sprinterovi, natoz chrt.
Navic, MB jede za sebe v F1. Doufam, ze hodi brzo rucnik, protoze jim to nejde uz hodne dlouho. A stihli zmrvit (vzit sebou) sportovni znacku par excellance, McLaren. V DTM si aspon nasli firmu, ktera jede za ne.

a stavim sa ze ten japoncik by bola ta "hviezdna" impreza.vsak?toto nepochopim ked porovnavaju nemecke auta(bmw,mb,audi)s japonmi.uz sa tesim ked spravi subaru nejaky motor vacsieho objemu ci sa nerozpadne po prvom nastartovani.a som zvedavy ci bude zase tolko papat ako ta 2lit. impreza.2 liter ale zere jak 3 liter.

di se bodnou lamo!

Lol

Takze podle tebe je to, co je novejsi nez to, co mas v garazi, automaticky "posrani hodne"?
Prober se clovece, kdyz reknu ze ten film stal za * tak to neznamena ze natocim lepsi...

chlapečku, když tomu nerozumíš, tak sem ani nepiš - speedshift je klasická 5stupňová automatika upravená u AMG, má o něco kratší dobu řazení - asi o 35 % , to je vše!

je to tak,je to zrychlený automat ::))

je asi o 40 procent.rychlejší.

jo, sory, byl sem trochu popletenej, ten zazrak se menuje ZeroShift, nak se mi to popletlo, www.zeroshift.com tam toho dost objasnej.
je z tohohle nekdo moudrej???

ZeroShift is a new technology for shifting gear ratios in zero milliseconds. The ZeroShift mechanism replaces synchromesh or dog-clutches so most manual transmissions can be converted. Additionally, ZeroShift FlatLiner is a control system that manages the shift for a smooth transition. FlatLiner manages the engine inertia and engine speed. While ‘modifying’ existing transmissions is possible, this is simply a fast-track route to market. A 100% ZeroShift gearbox can be more compact and fully automated without shift forks and rails/barrels.
------- FASTEST & SMOOTHEST-------

Never before have ‘smoothest’ and ‘fastest’ coincided. Never before have smoothest and lightest/smallest coincided. ZeroShift is fastest, smoothest, lightest, smallest AND most efficient (in mechanical and emissions terms). In ANY transmission application, ZeroShift will deliver an improvement over whatever transmission is currently used. ZeroShift engineering simplicity and elegance also mean its component count is less than other transmissions.

Firstly, a ZeroShift ratio change is smooth so acceleration or longitudinal ‘g’ force is uninterrupted through the shift - the yellow ZeroShift ‘g’ trace is a straight line. A manual or AMT transmission will have a pronounced dip (the white line). An automatic will gently slur through the shift (the grey line). Only one other gearbox can match ZeroShift’s ‘g’ trace: a dual-clutch transmission (DCT, or DSG in Audi-speak). ZeroShift beats DCT in every other discipline.
------- FLATLINER -------

The concept of an instant shift - given that the world has done without for nearly a century - is alien. It would appear that to change gear instantly demands an instant speed change of the crankshaft. This is true but this is not what happens in a ZeroShift. The elliptical highlight in the diagram shows that the engine revs adjust over time and the slope (rate of change) is dynamically adjusted by the FlatLiner controls.

So: ZeroShift does not detonate the transmission or the engine. In fact, ZeroShift is easier on the engine, the clutch, the transmission and all the joints and bushes on the way to the driven wheels.
------- THE REVOLUTION -------

ZeroShift is capable of replacing EVERY type of current transmission. From Racecar Engineering magazine (Feb 2004):
“ZeroShift has the potential to revolutionise automotive transmissions to the point where, putting our necks on the line here, it is reasonable to expect that in 10 years time every [vehicle] in the world will be built with a gearbox operating on the ZeroShift principle. … be prepared for a revolution.”
------- 8 ZEROSHIFT FACTS -------
1. ZeroShift can be up to 40% lighter and smaller than a manual transmission, currently the smallest and lightest gearbox type
2. ZeroShift is as mechanically efficient as a manual transmission, currently the most mechanically efficient. By being smaller and lighter, ZeroShift contributes to better vehicle fuel economy
3. ZeroShift is the fastest shift - you cannot go quicker than zero milliseconds.
4. ZeroShift is the smoothest shift - driveline torque is constant across a shift so longitudinal ‘g’ (acceleration) is constant
5. ZeroShift further assists fuel economy (and reduces emissions) because FlatLiner eliminates fuel enrichment ‘spikes’ in shifts. FlatLiner makes tiny, accurate adjustments
6. ZeroShift en***ges the move towards smaller engined vehicles by delivering a performance advantage between the gears rather than ‘in gears’. A 1.4 litre ZeroShift car would outperform a 1.6 manual and be as smooth as the 2.0 automatic (which it would also outperform!)
7. ZeroShift is relevant to ALL vehicle/transmission sectors because - as can be seen above - it beats or matches ‘best of the rest’ in every category
8. ZeroShift is fastest and smoothest so the same transmission type is equally effective in an F1 car and a limousine. It delivers the best performance and the best fuel economy. The ability to marry opposite extremes is unique and gives rise to a unique new way of driving called [CLASSIFIED - embargo 00:00 02/04/04].
------- GEARBOX TYPES -------

To fully appreciate ZeroShift’s extraordinary claims and the media’s extraordinary prophecies, it is worth quickly reviewing the last century, and in particular the last couple of decades, of gearbox design.
------- THE CLASSICS -------

There are two basic transmission types: synchromesh manual (originated 1920s) and planetary automatics (originated 1930s). A crude but effective evolution of the synchro manual is a constant mesh manual with dog clutches replacing the synchromesh elements. ‘Dog boxes’ are unsuitable for road cars but highly effective in racing cars - Formula 1 cars use sequential dog boxes.

There are three (or two and a bit) ‘core’ transmission types: manual and auto (the classic showroom choice) and the dog box (the only choice if you are a racer). So what’s happened in the last few years? Don’t we have the choice of CVT, IVT, AMT, SMG, DCT, DSG, Selespeed, F1, Sensotronic, Tiptronic....? So don’t we have more choice than ever? More features than ever? Read on...
------- THE VARIABLES -------

CVT (continuously variable transmission) has never caught on in volumes. It has its advocates but it replaces neither of the classic showroom choices.

IVT (infinitely variable transmission). Similar concept to CVT (ie a ‘stepless’ transmission) but it uses a ‘variator’ instead of bands and belts to give infinite gear ratios. Like CVT, it replaces neither of the classics. Unlike CVT, you can’t buy it in a showroom yet.

A quick note to finish off the CVT and IVT issue: F1 teams would not have more than 7 gears even if the regulations allowed. One can conclude from this that there is no need to have more than 7 gears ...so why would you need ‘continuously variable’ or ‘infinite’ ratios? Given that engines have a continuously/infinitely variable throttle and a broad power/efficiency band, it is easy to understand why 7 gears will suffice.
------- ROBOT WARS -------

AMT, SMG, Selespeed, F1, Cambiocorsa ...are all basically the same principle. AMT (automated manual transmission) is the generic term, the others are product names for BMW, Alfa Romeo, Ferrari and Maserati AMT systems. Quite often - just like CVT - the AMT option sits alongside ‘the classics’ rather than replacing either. However, Maserati have just launched the Quattroporte with only AMT and the media reaction has not been kind. Similarly, the AMT-only Aston Martin Vanquish has met such a fate.

So what is the problem? AMT is a manual that can masquerade as an automatic. It does this by adding weight, complexity and cost to a manual ...but the sum of all the parts is probably still a bit less cost than an automatic. AMT is a ‘robot’ doing the clutch and gearstick moving for you. For the ‘convenience’ of instructing the robot via ‘F1-style’ paddles, you save yourself the effort of changing gear. However, the robot - despite successive versions of software - still slams through the gears with the mechanical sympathy of a car thief!

‘Tiptronic’ (first introduced by Porsche in the 911) and subsequent other ‘somethingtronic’ automatics are the converse of AMT. They are automatics with added complexity. These are automatics that can masquerade as a manual.

AMT (manual + auto mode) and Tiptronic (auto + manual override), do not replace ‘the classics’. Tiptronics are esoteric automatics. Pitched at the sports/luxury sector, they are extraordinary engineering feats and their ‘functionality’ and ‘intelligence’ is all part of the status proposition. Mechanical losses are reduced by locking torque convertors (prevents fuelsapping slip) or offset by supercharged brute force in the certain knowledge that while the planet dies, the plutocrat at the helm ‘can afford it’.

AMTs are fundamentally flawed - whether it is ever possible or economic to force robots and software to have, under all conditions, the mechanical sympathy of a driving legend like Sir Jackie Stewart is debatable...
------- THE ILLUSION -------

...which is largely what opened the door to the most complicated manual transmission derivative of all: the dual clutch transmission (DCT) aka DSG in Audispeak.

DCT is a truly fascinating product. Two manual gearbox shafts are integrated into one another (one with the odd gears, one with the even gears) with a clutch on each shaft. To drive DCT requires a robot for the clutches and gear selection and a computer to choreograph the gearshifts. Dual clutch pre-selects the next gear and then releases the clutch on one shaft while engaging the other. There is a transition point where the two clutches work against one another.

The DCT transition duration is very close to ZeroShift’s zero milliseconds - 20ms to 30ms would be realistic. That’s faster than an F1 car’s 50ms. Impressed? To expose the REAL time to shift, try 5 to 4 to 3 in a hurry, say, to overtake a truck. A DCT can only go 5-4-3 sequentially, skipping ratios is impossible.

DCT is “the Emperor’s New Gearbox”, an illusion of progress. It costs nearly as much as an automatic. It replaces neither of the classics - a manual is faster, an automatic is ‘lazier’. DCT’s “fastest gearshift” crown is stolen by ZeroShift but the value of DCT’s crown was, in any case, frittered away by its weight and mechanical inefficiency. A competent driver in a manual car would outperform a DCT driver every time.

Compare the 0-60 time, the CO emissions, the price and the kerb weight of an Audi A3 with a manual transmission and with a DSG gearbox. Despite the ‘fastest gearshift’ before the arrival of ZeroShift, the DSG-equipped car accelerates slower and drinks more fuel. Just like an automatic...

Wole to je jak rudý právo ::)))

Taky z toho nejsem moudrej.

sory lidi, byl sem z toho auta trochu roztrzitej, to se da pochopit, ne?
ten zazrak vo kkterym sem psal se menuje ZeroShift, podivejte se na www.zeroshift.com , ja z toho obrazku moudrej nebyl.

tak to sa pozera pekne ako sa to vsetkym paci.mne sa straaasne paci a hlavne motorovo ->3.9 ??? obmedzene na 320km\h ??? takymto krokom a o 5 rokov budeme jazdit 300km\h po dialniciach. to s tym BMW M3 CLS DTM F1 je dobreeeee.

..chtělo by to real pojezd.Musí to mastit moc moc KRÁSNĚ.

Hmmm, mne se to taky libi. Skoda, ze to neni delany na cesky silnice
At tomu daji rychlejsi prevodovku, pls!

jako manuál :)

so 120-kou,co?:)))))))

to uvidiš mazec

ale něco by mohli udělat v F1, a to tak že rychle.prosím

jo taky dělá na nových C klasse v DTM.Tak to asi nebudou žádný vořezávatka

Kdo to je H.W.A.? neznám

H.W.A. je přímo odpovědná za C v DTM. Je to známá ale malá firma,co se tíče Mercedesu.
