Re: PPI Audi R8
Sincer nu vad de ce sa dai banii pe R8 diesel , nu gasesc nici un argument in favoarea lui .. 1. V12-le tdi care se vrea sportiv e clar ca va consuma in prostie, 2. faptul ca are 2 turbine si cuplul acela de camion pe cutie manuala imi pune intreabari asupra fiabilitati comparativ cu motorul genial 4.2 aspirat, iar sunetul de diesel , mi se pare penibil, mi-ar fi rusine sa-l pornesc intre alte supercar-uri .. A .. am gasit un avatantaj , daca vrei sa iti pierzi urma ii dai talpa la masina si te ascunzi dupa un nor negru :-) :-) (glumesc :oops:)

@wtcvictim...din pozele de pe topicurile cu r8 dizal se observa niste diferente in materie de design,in favoarea dieselului care arata si mai frumos R8-ul diesel este un concept interesant,nu va obliga nimeni sa il cumparati sau sa il laudati.cei de la audi au incercat ceva...unora le place,altora nu!asa ca lasati saraca masina in pace.imediat ati sarit la afirmatii gen niciodata nu va fi supercar diesel sau ca nu o sa se apropie de performantele unui benzinar etc...o seara buna |
Re: PPI Audi R8
bai, mai lasati-ma cu cifrele de 0-100km.... da sunt si alea bune, dar unde sunt vitezele maxime, timpii de a ajunge la vitezele maxime, cat scoate pe 400m, cat ii ia 0-200, etc....
amintitiva testul top gear cu Carrera vs R8... carrera fugea de pe loc si era in fata, deci ca 0-100 era in fata si tendinta ar fi sa zici ca e mai rapida, dar dupa ce lua avansul initial, tot pierdea incet incet, pana la 500m cand erau bara la bara din nou.... 0-100km/h nu spune toata povestea |
Re: PPI Audi R8
Ideea e nu ca trebuia neaparat ca 4.2FSI de pe A8 sa fie adus la nivelul celui de pe R8 ci ca in primul caz mai avea mult potential.Or ce chestie e sa pui cununa TDI-ului ca are demaraj mai rapid daca celuilalt se stie ca nu i-ai dat nici pe departe sa duca cat poate?Iar 0.4s nu zic ca e o diferenta insignifianta, totusi nu e atat de mare tinand cont de diferentele de pe hartie.Sa vedem ce va putea motorul de 5.0 pe un R8.Deci nu vorba ca R8 diesel are performante slabe, doar ca nu vad rostul a se compara cu atat fast cu celalalt cu motor mult mai mic.Respectand proportiile, nu cam ca si cum ai compara 3.0TDI-ul cu un 2.0i, chiar in conditiile in care cel de 2.0 e impins la maxim (ca motor aspirat).
@Nu stiu exact ce greutate are R8-ul (TDI), Lamborghiniurile stiu ca sunt grele, Gallardo are cam 1600kg, iar Murcielago din cate stiu se apropie de 1800 (cred ca in jur de 1600 are R8-ul TDI...FSI-ul are pe la 1550). @Bloodfart, e vorba de Carrera S? |

After winning the event so many times outright, Audi wanted to promote diesel which was outselling gasolone in Europe. The move was daring, since the required engineering would be heavier, but that was offset by the increased energy levels in diesel that gave better economy Another benefit of diesel was its torque and Audi set out to design the most powerful diesel in the world. To deal with internal stress, Mahle supplied special two piece pistons were made that were divided to provide a cooling channel. These had to deal with the pressure provided twin turbos that made over 650 bhp. Audi Director Wolfgang Ullrich had a huge distaste for black smoke which is commonly associated with oil burning diesels, so a special particulate filter was included in the exhaust. These were engineered by DOW and made from chemically treated ceramic honeycomb. 2006/06/18 - AUDI has written an important chapter in the history of motor racing with its historic triumph in the Le Mans 24 Hour race. The new Audi R10 TDI was the first diesel car to win arguably the toughest car race in the world. In front of a record crowd of 235,000 spectators, Frank Biela (Germany), Emanuele Pirro (Italy) and Marco Werner (Germany) clinched the sixth and most important Le Mans win for Audi so far. The fans on the race track and a worldwide audience of millions of TV viewers saw an impressive demonstration of Audi TDI Power and the performance of modern diesel engines. The brace of Audi R10 TDI cars, powered by a 650 hp V12 TDI engine, were by far the fastest and most economical cars. During the entire race, one of the new diesel sportscars from Ingolstadt was at the head of the field. Le Mans record winner Tom Kristensen drove the fastest lap of the race, setting a 3m 31.211s time, and he was the first driver at the wheel of an LM P1 sportscar to cover 16 laps with one fuel load. Completing 380 laps, Audi also set a new distance record. In the race, the advantage in fuel consumption of the Audi TDI Power was visible for the spectators too: on average, the Audi drivers only pitted every 14 laps to refuel 90 litres of Shell V-Power Diesel. The opposition, who relies on petrol engines, had to pit considerably more often. The fans were also impressed just how quiet an environmentally friendly 650-hp sportscar can be. --- 2006/03/19 - The new Audi R10 TDI has immediately written motorsport history in its first outing: Dindo Capello (Italy), Tom Kristensen (Denmark) and Allan McNish (Scotland) won the 12-hour race at Sebring (USA) achieving the first ever victory of a Diesel powered sportscar. Tom Kristensen became the first driver to win America?s most famous endurance race for a fourth time, achieving another record after his record seventh Le Mans victory from last year. Allan McNish had already shown the potential of the 650-hp V12 TDI engine with a record-breaking pole position time in qualifying. Because the heat exchanger had to be replaced after the morning warm-up, Dindo Capello was forced to start the number two R10 TDI from the pit-lane starting his chase from the back of the field. It took Capello only half an hour before he had moved from 35th and last position to second just behind the sister car of Frank Biela. Shortly before the end of the second hour, the Italian took the lead, which the number two R10 TDI kept until the finish. Only changing the fuel filter and two loose wheel nuts caused unscheduled pit-stops. The number one Audi R10 TDI that had clearly led the race for the first two hours did not reach the finish. The car was withdrawn just before one-third distance due to an overheated engine. ---- 13.12.2005- Audi will become the world's first automobile manufacturer to fight for overall victory with a diesel engine in the famous 24 Hours of Le Mans. The all-new Audi R10 is powered by a totally new 5.5-litre, twelve-cylinder bi-turbo TDI engine, which is extremely quiet and economical. The Le Mans Prototype significantly exceeds the power produced by the majority of previous Audi racing cars - including that of its victorious R8 predecessor. The heart of the Audi R10 is a completely new V12 TDI engine with a cubic capacity of 5.5 litres - the maximum permitted at Le Mans. Audi ventures into previously unexplored diesel-engine terrain with power exceeding 650 hp (485 kw) and torque of more than 811 ft lbs (1100 nm) from the V12 power plant. At first glance, it is visible that the new Audi R10 carries genes from the extremely successful R8, nevertheless, the new LM P1 sportscar's chassis is a new design. One of the most significant differences to its predecessor, the R8, is the integration of monocoque and bodywork. The R8 still had a traditional chassis clothed in synthetic bodywork, whereas the majority of the carbon-fibre parts belonging to the R10 monocoque are now suspended directly in the air flow and therefore require no additional fairings. The modular design and serviceability known from the R8 was retained, but further refined, in the basic concept. It is not only the rear bodywork section of the R10 that can be removed at the flick of a wrist, the front section, including crash structure, is also removable to ease access to the front suspension for the mechanics. It is possible to change the gearbox and its internals within a short space of time. The new Audi R10 successfully completed its first test at the end of November. An extensive test programme, including the 12-hour race at Sebring (USA) on 18 March, is scheduled before the 24 Hours of Le Mans on 17/18 June 2006. The development team from Audi Sport is supported by Reinhold Joest's squad, which also performed this task during the R8 project. Stiai de acest audi diesel insignifiant?? |
Re: PPI Audi R8
Of, iarasi Le Mans :rolleyes2...s-a vorbit si de asta de mai multe ori.O sa-l vad ce face TDI-ul cand vor avea si benzinarele libertatea pe care o au in LM1 si LM2 si ALM.De ce acolo R10 o ia cu chiote de la Acura si de la Porsche, constant si "sangeros"....acestea avand motoare mult mai mici (si tot ce au putut face a fost sa se planga ca niste babute ca vezi chipurile benzinarele sunt cu 50kg mai usoare...cealalta parte insa bineinteles nu conteaza, nu se vede).O sa zica Anaconda ca iar pomenesc de asta.Pai daca se tot da cu aceeasi placa.Daca-i legi la ala cu care te dai la intrecere de alergare sireturile intre ele si pe urma te lauzi ca l-ai batut......nu e nici un "torque" asa de special, sunt benzinare care la aceeasi capacitate au acelasi cuplu la o compresie pe jumatate fata de R10.E fix, dar fix tot marketing.Putem face pariu ca oricand un benzinar de acolo, asa cum sunt ele, la numai 4000cc il bate oricand (precum o poate face si in ALM), dar pur si simplu nu s-a jucat cinstit.Tu ai vazut vreodata tabelul ala insignifiant de restrictions din regulament?

Re: PPI Audi R8
Ca sa nu fiu inteles gresit, nu vreau sa fac un versus benzina vs diesel.La masinile normale, ca sa le zic asa, poti intr-adevar cum spunea Anaconda sa ai o serie de avantaje cu dieselul.Ai consumul, ai cuplul la turatii mici, ai performante cat se poate de decente (cine poate spune de exemplu ca un Audi quattro 2.5TDI nu trage bine?), in plus am mers chiar alaltaieri cu TDCI-ul unui coleg si am ramas destul de uimit sa vad ca la 120km/h avea un consum (foarte bun...in jur de 4.8), iar la 150km/h chiar putin mai mic, la peste 160/h incepand sa creasca, dar cu o panta mai lina ca la un benzinar.Mai este si comoditatea in condus, poti merge intre 60 si 150 cu treapta a 4-a si ai si acceleratie fara a fi nevoie neaparat sa retrogradezi.Un turbo pe benzina va fi performant, dar isi va avea pretul sau intr-un consum consistent.Aici insa e un alt capitol, e domeniul super-cars (si s-a atins si motorsportul).

Re: PPI Audi R8
carutasu incearca sa va spuna ceva foarte simplu, dar pare ca va scapa:
Cand comparatia va fi intre motorul cu bloc de marime X cu turbina de marimea Y care merge pe benzina, si intre motorul cu bloc de marime X cu turbina de marimea Y care merge pe motorina atunci sa vina audi sa se laude, nu cand un motor e jumate din marimea altuia. Le dai la ingineri mana libera sa faca ce vor cu restul motorului, doar volumul total si diametrul turbinei ramanand la fel, si vezi care scoate un monstru mai mare... Cand un motorinar o sa se compare, atunci sa aiba audi sau altii pretentia de al pune intr-o supermasina... Pana atunci, ce conteaza ca a castigat la Le Mans? Cat de des o sa faci drumuri trans-continentale, si in care sa fi si asa de in graba incat sa trebuiasca sa tii opririle la un absolut minim... sa fim seriosi, lumea reala e PLINA de benzinarii, si chiar daca ar trebui sa faci plinu la fiecare 100 de kilometrii, nu vad sa ramai pe undeva in Europa in pana... Si cand ai 100,000 de europ pentru R8, ti se rupe de 3euro in plus la rezervor pentru diesel, si preferi sa poti sa agati femei cu masina, nu doar sa le sperii cu mirosu si sunetu.... |
Re: PPI Audi R8
asa mai merge cu razor asta......superb

Re: PPI Audi R8
mi-a picat fisa in sfarshit.... R8 TDI o sa fie facut in serie redusa, pentru alora care le place sa mearga la curse de endurance.. deci da, acolo cred ca o sa faca bine, si ala cred ca e marketul tintit, nu omu cu bani care vrea ceva misto cu care sa se plimbe si din cand in cand sa bage pedala
