In primul rand consumul mediu nu se calculeaza asa cum crezi tu. Adica nu se acorda pondere egala distantei parcurse in oras cu cea din afara. Ce pot sa zic, mai documentati-va si dupa aia mai vorbim !

Deci repet, cifrele alea nu sunt scoase din burta ! Ele sunt stabilite in urma unor teste cat se poate de riguroase (sau stiintifice cum vrei sa le spui), care chiar daca nu reflecta consumul masinii in conditii de utilizare normala sunt foarte utile ca si termen de comparatie. Ce dracu e asa greu de inteles ??? Parca suntem la gradinita sa mor eu.

The fuel consumption testing scheme is intended to give car buyers comparative information about the fuel consumption of different models in standard tests.

Nearly all new car models which are type approved for sale in Europe have to undergo the standard tests to determine their fuel consumption. This text contains the results of those tests supplied to the DfT for new cars expected to be on sale after May 2005.

WHAT ARE THE STANDARD TESTS?

Official fuel consumption test procedures have been in use since the 1970's. EU Directive 80/1268/EEC (as last amended by 2004/3/EC) describes the tests which the all new cars on sale after 1 January 2001 have been required to take.

FUEL CONSUMPTION TEST (Directive 80/1268/EEC as amended by 2004/3/EC)

The new test has been agreed internationally and provides results that are more representative of actual average on-road fuel consumption than previous tests. There are two parts: an urban and an extra-urban cycle. The test cycle is the same as that used to determine the official exhaust emission classification for the model of vehicle in question.

The cars tested have to be run in and must have been driven for at least 1,800 miles (3,000 kilometres) before testing.

Urban cycle
The urban test cycle is carried out in a laboratory at an ambient temperature of 20°C to 30°C on a rolling road from a cold start, i.e. the engine has not run for several hours. The cycle consists of a series of accelerations, steady speeds, decelerations and idling. Maximum speed is 31 mph (50 km/h), average speed 12 mph (19 km/h) and the distance covered is 2.5 miles (4 km). The cycle is shown as Part One in the diagram below.

Extra-urban cycle
This cycle is conducted immediately following the urban cycle and consists of roughly half steady-speed driving and the remainder accelerations, decelerations, and some idling. Maximum speed is 75 mph (120 km/h), average speed is 39 mph (63 km/h) and the distance covered is 4.3 miles (7 km). The cycle is shown as Part Two in the diagram below.

Combined Fuel Consumption Figure
The combined figure presented is for the urban and the extra-urban cycle together. It is therefore an average of the two parts of the test, weighted by the distances covered in each part.

Baietii aia de la Alfa inca n-au terminat de testat si construit masina, si tu stii deja cat o sa consume? Cum ai calculat? Mie imi da cu virgula. Mi se pare mie sau tie chiar iti sta in gat 159 GTA asta? Cum naiba puteti face asemenea afirmatii, avand un model NELANSAT ca subiect de discutie? "Ho, Tibi draga, ca nu furam!"

Unde-am spus eu ca stiu cat o sa consume Alfa bre ? Am spus "sa zicem ca consuma 15 litri" tocmai pentru ca nu stiu exact cat va consuma (dar avand in vedere ca se zvoneste ca va fi dotat cu motorul de 4.2 litri de pe maserati quattroporte care consuma 14.8 e si foarte greu sa aproximezi acest lucru nu?? :lol:)...iar concluzia citata de tine era valabila doar daca premisa era adevarata, LOGIC. Hai gata ca deja incep sa ma enervez si nu cred ca are rost. Eu spun ceva si voi intelegeti exact pe dos.

p.s. O consuma S500 ala 11 la suta cand mi-oi vedea eu ceafa, prietene. Eventual in garaj, cu motorul oprit.

Pai daca respecti normele de testare specificate in link-ul de mai sus o sa vezi ca atat iti iese. Ca in realitate nu prea ai cum sa faci acest lucru, e alta mancare de peste. Dar tocmai de aia si ei spun ca cifrele alea nu au decat un rol COMPARATIV :rolleyes2

A si in legatura cu GTA vs M3 ala era un exemplu pur teoretic, puteai sa inlocuiesti GTA-ul cu orice alta masina dar concluzia era aceeasi: daca o masina consuma in specificatii (sau ma rog, in testele respective) cu 25 % mai putin decat alta, ea si in realitate va consuma cu 25% mai putin. Asta era ideea dar vad ca tu in loc sa-mi dai dreptate ai sarit la gatul meu ca cica am ceva cu alfa :lol: N-am nimic cu alfa ba din contra imi place la nebunie. Cu motoarele maserati am insa o problema, nu ca n-ar fi bune dar consuma mult prea mult si ofera performante mai slabe decat ale concurentei. Ceea ce e foarte pacat pentru ca la capitolul sunet nu le intrece nimeni.
