N/U: Audi R8 DSG

beckervdo · 13 Maggio 2011

Al posto dell'attuale R-Tronic dovrebbe debuttare il nuovo DSG 7 rapporti che regge coppie anche di 700 N m.

Is Audi readying a new dual-clutch transmission for its R8? It appears that way, since spies caught two Audi R8s testing in the Austrian Alps, loaded to the gills with a vast array of testing sensors and equipment. The wheels are fully covered, and capped by test sensors at each wheel hub. The interior is filled with multiple computers, and wires leading into the engine bay and transmission tunnel. It appears that a new electric parking brake has been added next to the lever for the standard parking brake. There is a lot going on, demanding closer scrutiny.
The mountain range where these prototypes were caught is a known testing center for two primary automotive concerns - brakes and transmissions. Close inspection of the interior shots seems to narrow down these prototypes as transmission testbeds. A printed sign inside the R8 coupe tester is partially visible, which reads: "Kupplung sehr empfindlich", meaning that the clutch is very sensitive, or touchy. A further rough translation of the sign goes on to encourage caution, because the clutch is prone to grinding. It seems clear that the transmissions in play here are in an early stage of development and represent a marked change over the current R8's R-Tronic gearbox.
While the VW/Audi group has largely pioneered the dual-clutch automatic transmission (DSG), the R8's optional R-Tronic transmission is only a single-clutch unit, and has received criticism for its rather herky-jerky nature, especially at lower speeds. We hear that due to technical issues, creating a dual-clutch tranny for the R8 is difficult - especially considering the power and torque on tap--and the low volume nature of the R8 makes engineering such a system not necessarily cost-effective. These issues aside, many still question how Audi's halo car can persist with anything less than a top-performing DSG transmission.
Audi is clearly hard at work on some complex changes for the R8's transmission, and to us at least, a dual-clutch transmission would seem to be the only direction Audi could logically go to change or improve the R8. Rumors have been afoot for a while that the R8 would indeed get a new seven-speed dual-clutch transmission. So far we have only seen V8-powered R8s (both as coupe and spyder variants) undergoing these tests, so it remains to be seen if the V-10-powered R8s will be similarly reworked. Until the engineers allow us to rifle through the rest of the paperwork we can see hidden among all that testing gear, observation-based speculation is all we can bring at this point.

era ora cavolo, sarà perfetta dopo...

peccato non ci sia anche una turbina di mezzo, si potrebbe salire di potenza con estrema facilità sfruttando la maggiore tolleranza del cambio...

Per il V8 non ci saran sicuramente problemi, visto che lo monta l'RS5 con lo stesso cambio..

ma il V10? voglio vedere se esce l'R8 V10 DSG chi comprerà più la gallardo..

Un pò drastico direi... Non vedo perchè

Problemi col raffreddamento,anche se quello ricordo fosse il v12...

Comunque voglio proprio sentire il v10 a "scoreggiare" mentre cambia /emoticons/biggrin@2x.png 2x" width="20" height="20" />

Perchè originariamente la R8 GT doveva esser equipaggiata con il V10 Biturbo della RS6. (560 CV facili facili).

Poi il 90% dei prototipi di tal vettura prendevano fuoco per problemi di surriscaldamento nel vano motore.

Hanno dovuto ripiegare sul motore lambo preso di pari-passo.

La R8 è una splendida auto, ma le riviste che l'hanno provata continuano a definirla troppo morbida come assetto e non così incisiva come le lambo, nonostante siano "cugine". Forse per chi vuole solo un auto che faccia effetto è un'ottima soluzione, ancor + se la usa in città per andare in ufficio o cmq per muoversi spesso, mentre chi vuole le prestazioni vere credo rimarrà fedele ai tori lamborghini

E l'efficacia del cambio? Secondo me non inciderà poco..

sulla v10 forse monteranno l'ISR dell'aventador, mi viene da pensare...

l'importante è che sul V8 ci sia il DSG...

Today we've stumbled across this photo released by Audi in some seemingly unrelated materials... perhaps inadvertently, but then again Audi never does things inadvertently. Pardon the pixelation, but we blew it up and pulled some shadows out of that grille to get a better view.
Meant to show off Audi's LED design prowess, we're 99% certain the design buck shown in the shot also reveals next year's planned R8 facelift. When we first glanced at the small photo, all we saw was the headlight. Taking a second look, the photo really grabbed our attention.

Here's what we see:

1. Unlike the e-tron concept, e-tron spyder concept or other sportscar designs Audi has released in concept form, this is quite obviously an R8... but with several differences and that is most interesting indeed. The R8 facelift is due soon... but how soon?

2. LED-rich, longer and more aggressively shaped headlight - It's possible this is a concept component, but likely not. First, it's not anything we've seen before... not e-tron or e-tron Spyder. If it is production, this suggests the R8's headlight assembly will stretch from the quarter panel entirely to the grille where it becomes pinpoint thin but still carries the amber glow of the turn signal.

2. Hexagonal take on the Audi grille - Notice how Audi's been cutting the corners off the top portion of its grille on the A8, A7, A6 and new A5? The cut is here on this grille too, subtle but there and noticeably different from the current R8 grille.

3. Grille Texture - Note the hole-style mesh of that grille. This is unlike anything we've seen in any current R8 and closer (but not exact) to the grille mesh texture of some RS cars.

Here's what we don't see:

1. Front Outer Intake Slats - To us this fascia looks unfinished. The R8's bold slat-work to the right and left of the main grille is a fairly fundamental part of its design. We doubt Audi will leave those side intakes completely open... but you never know. The no slate look is certainly very aggressive.

So What Else Do We Know

Word is, Audi has some very interesting R8 test mules running around in Germany. Spy photos have shown drivetrain mules and then there was that aggressively flared R8 GT that turned up at Nurburgring. We've also heard of mules fitted with the 2.5 TFSI and 3.0 TFSI, both sporting rear-wheel drive and possibly running S-tronic transmissions. Think Lamborghini Gallardo Balboni meets TT RS. "It's all part of Audi's experimentation in downsizing," said one source to us... or maybe it's just Rupert Stadler, Michael Dick and company's idea of a good time. Whatever they are, these aren't headed for production... this time around.

Sources close to Audi tell us that the Audi R8 product improvement drivetrain changes won't be as radically changed as those rear-wheel drive test mules. Expect the V8 and V10 to carry over but perhaps with a slight power bump. Don't count on the V10 being swapped for the much-anticipated 4.0T quite yet as the V10 is expected to continue on in the R8 and Lamborghini Gallardo despite the big engine's retirement in non-high-rev form from the S6 and S8.

The big news though will be the transmission. A dual-clutch S-tronic will replace the single clutch R-tronic transmission. As with S-tronic in Audi's other models, this new mid-engine S-tronic with twin clutches is expected to increase automatic mode drivability, which has been the biggest complaint about the current car.

Now Here's Where Things Get Interesting

We're told by someone who's seen production plans that production of the S-tronic begins as early as week 39. If that's so, then it's possible that the R8 product improvement (facelift) will be on at least the European market by this fall... which may mean the new R8 will bow at the Frankfurt Motor Show in September. Week 39 is the last week in September and there's no other auto show event at which to show the car during that time unless Audi goes for a stand alone event. If this proves true, times to watch for coverage here likely either at the Volkswagen Group reveal the night of September 12 (afternoon in the States) or on Media Day 1 on September 13.

Like we said, Audi doesn't slip photos by mistake. That we stumbled across this in materials provided to us makes us think the photo was cleared because the R8 product improvement is close... very close. If so, we'll see it at Frankfurt. If not, well, chalk it up to wishful thinking. It still remains possible that this is just a design buck of an alternative design that didn't get approved. That also happens. Still, we believe the chances are very high that this is the facelift.

Ma che dicono? A Francoforte l'R8 restyling Stronic???

beckervdo · 25 Agosto 2011

E' un fake quella immagine.

So finaly i've found it:

The picture shows a light design study of the "TU Dresden" (TU means technical university):

LUPINN · 10 Marzo 2012

Con tutta probabilità il quinto anniversario dell’Audi R8 sarà l’ultimo prima che venga introdotto il corposo aggiornamento di cui si mormora con insistenza. Lo conferma questo breve filmato, al termine del quale appare il profilo della “new Audi R8”. Secondo quanto riporta World Car Fans la sportiva dei quattro anelli riceverà nuovi paraurti anteriori e posteriori ed inediti gruppi ottici, oltre a qualche cavallo in più destinato ai motori V8 4.2 e V10 5.2: il primo raggiungerà i 450 CV, mentre il secondo verrà riposizionato a 540. Il cambio sequenziale R tronic potrebbe inoltre essere dismesso in favore del più moderno doppia frizione S tronic a sette marce. Debutterà a fine 2012.
