Ce noutate...veche...

Articolul de pe BBC NEWS
http://www.bbc.co.uk/news/business-21759258?print=true

QUOTE
Slick tyres are pumped hard to reduce rolling resistance. Brakes are adjusted, or at times even disconnected, to reduce friction. Cracks between body panels and windows are taped up to reduce air resistance. Sometimes they even remove the wing mirrors.

"About half the official improvements in fuel efficiency during the last decade results from efforts made by carmakers during testing, rather than from real-life improvements," Mr Archer says.

In reality, some models emit 50% more CO2 than the official figures claim, while others emit some 15% more than claimed. They also use more fuel, as noted by many a motoring journalist.


Articolul BBC mentioneaza organizatia Transport Environment care nu imi este clar ce face. Insa au o pagina de web si citeva articole care detaliaza problema.

Adevarul nu ar trebui sa surprinda pe nimeni. In Statele Unite nu doar Hyundai - KIA au fost gasite cu metode creative in priviinta consumului ci si Toyota (Prius). Doar ca in USA Agentia de Protectia Mediului testeaza toate masinile iar numerele oficiale sint cele publicate de ei - si in general sint mult mai mici decit cele precizate de producatori pe pagina de web etc. Pentru 2008 Agentia de Protectia Mediului a reviziut testul si acum cifrele sint mult mai aproape de realitate.

NOTA PERSONALA
Subaru meu cind l-am cumparat scotea oficial 25 mpg pe autostrada. Nu a scos niciodata 25 mpg. A scos 27 mpg ne-molestata iar dupa m-am apucat de prostii cu ea, a ajuns spre 31-33. Cu timpul (mai ales cu noul turbo) a scazut la un 30-31 insa cifrele oficiale actuale indica 23 mpg pe autostrada. Chiar cu 1 mpg mai prost ca Jeep-ul proaspat cumparat (care este o masina cu un CoD = 0.37 comparat cu 0.29 la Subaru)iar Jeep-ul cintareste cu cca 800 kg in plus. Mai punem la socoteala faptil ca Jeep-ul poate folosi benzina regular pe cind Subaru are nevoie de premium si mai ca as zice ca...pretul de operare in $/mila condusa va fi similar sau poate chiar mai mic la Jeep. And on this bombshell - I bought an SUV to save money !
