40% Yarisa koji se sad prodaju u Evropi su hibridi! Nemamo odavde pravi osećaj pošto su nam hibridi još egzotika.

A da li je većina kupaca dizela znala za zagađivanje? Kola su ispunjavala najnovije eko norme, na sve strane se trubilo da su dizelaši sad čistiji od benzinaca, lepili su im oznake green, eco, blue efficiency, itd. Po meni nisu čak ni proizvođači krivi. Ako je neko odgovoran to je birokratska ekipa koji je propisala način merenja eko normi takav da ne odgovara realnoj vožnji. Ako propisuješ pravila, svi ih ispoštuju a rezultati nisu kakve si hteo - bato, do tebe je.

Proizvodjaci su tu najmanje krivi (osim VW, oni bas nisu normalni sta su radili).
Oni su pravili sta trziste trazi (a politika je navela trziste da trazi to sto trazi). Naravno da su se dovijali kako znaju i umeju da unutar propisanih pravila postignu sta treba da postignu. Jel trebao npr Daimler da iz moralnih razloga se ne dovija i ne trazi rupe u pravilima i lepo kaze mi nismo sposobni da napravimo dizel motor, ako hocete dizel kupite nesto od konkurencije?
Dakle nisu valjala pravila, nije valjala metodologija sprovodjenja testova, pokrite se usima i gledajte kako da resite probleme u buducnosti.

apsolutno, sećam se Honda radnje u Karađorđevoj pre 7-8 godina, radio neki matori prodavac kao iz američkih filmova, hteo da upali CR-V 2,2 u lokalu da mi pojasni kako je čistiji vazduh koji izađe nego onaj što je ušao :kezo:

nidza je napisao:Najbolje da je tako jednostavno. Šta sa dizel motorima u komercijalnim vozilima i raznim statičnim dizel agregatima, termoelektranama, sve to ne zagađuje vazduh, samo automobili? Nije nego.
Pored komercijalnog programa, 95% isporučenih Land Rovera u Evropi su dizeli (kontam da je sličan procenat za SUV modele svih proizvođača), 80% Volvoa takođe. 3 od 4 prodata bimmera su sa dizel motorima. Ulaganje u dizel agregate se ne smanjuje. Mercedes je u novi 2.0 uložio preko dve milijarde. BMW pre neki dan predstavio novi 4 turbo M550d koji do 100 stiže za 4.4s. To su sve činjenice.

Nagla zabrana je nemoguća misija ali će ih vremenom izbacivati iz B i C segmenta. To je neka tranzicija koja će trajati min 10ak godina a do tada će mreža el punjača biti dovoljno razvijena da bi se većina prebacila EV.

Petrolhedovi će moći da biraju između 1.0 - 1.5 trocilindričnih plug in hibrida :)

Postoji efikasno rešenje za dizele (naročito teretna vozila i autobuse), ali košta i ima i svojih mana (naravno), a to je konverzija na metan (metan se meša sa dizelom), time se efikasno sagorevaju sve te štetne čestice, odnosni najveći deo njih. Mana je što treba kao i kod vozila na TNG/metan vući dodatni rezervoar, smanjuje se prtljažnik, ali se istovremeno ostvaruje i lepa ušteda.

Bole ih ćoše, guraju hibridnu priču i imaju uspeha u tome.
To znam ali su kljuse u benzinskom rezimu. Kupis CH-R i osecas se da si uyeban jer je motor slab a kad pogledas auto ocekujes da bar malo moze da isprati izgled, a ne da motor ima aritmije kad ga upregnes. Valjda se auto kupi da se vozi a ne da ga stedis vise nego sebe samog.

VW will offer European diesel owners extended warranty, EU says
http://europe.autonews.com/article/2017 ... ty-eu-says

BRUSSELS -- Volkswagen Group has agreed to offer an extra two-year guarantee but no compensation to European customers, a European Commission spokesman said on Wednesday.

The offer was made in talks with Europe's consumer rights chief after the automaker cheated on emissions tests.

EU officials have piled pressure on VW to compensate European customers after it admitted to U.S. regulators that it installed illicit software in as many as 11 million diesel vehicles sold worldwide -- the majority of them in Europe.

Despite VW's admission of wrongdoing in the United States, it says it has not broken the law in Europe and sees no need to compensate consumers there.

VW Group CEO Matthias Mueller told the EU's commissioner for consumer affairs, Vera Jourova, earlier this week that the company would now offer European customers a two-year extended warranty, the Commission spokesman said.

However, commenting on the talks with the commissioner, VW did not confirm that it had agreed to extend its guarantee. The company instead referred back to earlier "confidence-building measures" including a commitment to fix all vehicles affected by this autumn, saying that updating the software would not detract from the car's performance.

"Volkswagen has said all along that it cares for every customer," it said in an email on Wednesday.

An extended warranty offer would be the first concession made by the company in response to mounting pressure from Brussels to do more for its diesel customers following months of talks with EU officials and more than a year after VW's emissions scandal scandal broke.

Jourova and other EU regulators have repeatedly expressed frustration over VW's attitude to European customers in not offering the cash payouts granted to U.S. owners of its cars.

But the European Union is limited in what it can do to pressure the company since the power to police the car industry currently lies with member states, which approve new car models that are then sold throughout the bloc.

Unlike the United States, a patchwork of different legal rules across the Europe Union also weakens the chances of car owners successfully suing carmakers.

Berlin demands costly German recall of 12 million diesel cars, report says
http://europe.autonews.com/article/2017 ... ars-report

BERLIN -- Germany's Transport Ministry is pushing carmakers to update the engine management software in up to 12 million diesel vehicles in the country, people familiar with the talks told Reuters.

The move shows how German lawmakers are flexing their muscles ahead of national elections on Sept. 24, forcing carmakers to reduce polluting nitrogen oxide emissions from diesel engines.

The dangers to public health from diesel fumes became a political issue in the wake of revelations in September 2015 that Volkswagen Group had systematically cheated emissions tests to sell cars that produced excessive pollution.

Germany's top car manufacturers volunteered a recall of 630,000 cars in April 2016 to fix diesel emissions management software but that failed to reassure regulators and policymakers that pollution levels are under control.

Since then several European cities including Stuttgart and Munich have considered banning some diesel vehicles, blaming emissions for causing increased respiratory disease.

On Monday, lawmakers upped the pressure in closed-door talks with the auto industry. The ministry is in discussions with German auto industry associations VDA and VDIK as well as representatives from local governments to try and cut nitrogen oxide pollution by about 25 percent, the sources said.

It could cost 1.5 billion to 2.5 billion euros ($1.7 billion to $2.8 billion) to update cars and the ministry is demanding that vehicles with engines conforming to the euro-4, euro-5 and euro-6 standards be part of the recall, government sources said.

The government has demanded that the auto industry shoulder the costs and is pushing for a solution to be presented before the elections in September.

Daimler accused of selling over 1 million cars with excess emissions, report says
http://europe.autonews.com/article/2017 ... -emissions

BERLIN -- Daimler AG has been accused of selling over a million cars with excessive emissions in Europe and the U.S., Sueddeutsche Zeitung newspaper said on Wednesday, citing a search warrant issued by a Stuttgart court.

Two months ago Stuttgart prosecutors searched Daimler sites in Germany following allegations of false advertising and the possible wrongful manipulation of exhaust gas treatment systems in diesel cars.

The Stuttgart local court's search warrant triggered the searches on May 23, Sueddeutsche Zeitung said.

According to that document, more than 1 million cars with excessive emissions, including various luxury Mercedes-Benz models, were sold in Europe and the U.S. between 2008 and 2016, said Sueddeutsche Zeitung, which researched the matter with regional broadcasters WDR and NDR.

A Daimler spokesman declined to comment on the continuing investigation by local prosecutors, adding the carmaker was fully cooperating with the authorities.

The cars in question are powered by engines codenamed OM 642 and OM 651, with prosecutors examining the possible use of defeat devices to manipulate emission levels during tests, the newspaper said.

There is a risk that the vehicles affected in Europe could be banned in the region, the newspaper said, again citing the search warrant.

The Daimler spokesman declined to comment on the report, describing it as "speculation," apart from saying the company did not see any danger of its cars being banned.

A spokesman for Stuttgart prosecutors declined to comment while Germany's transport ministry couldn't be reached for comment.

Carmakers across the globe have faced increased regulatory scrutiny over anti-pollution tests since Volkswagen admitted in September 2015 that it had installed secret software in its diesel cars in the United States to cheat nitrogen oxide emission tests.

Povodom optužbi upućenih PSA grupaciji, u vezi prekomerne emisije gasova.

Groupe PSA denies any fraud strategy and strongly reaffirms its technological choices
http://markets.businessinsider.com/news ... 1002353333

In response to press reports today, Groupe PSA indicates that it has not been contacted by
the judicial authorities. The group is outraged to learn that information has been provided to
third parties whereas Groupe PSA has never had access to the file submitted by the DGCCRF
to the public prosecutor's office, making it impossible for the group to put forward its arguments.
Groupe PSA has repeatedly explained its strategy regarding engine settings. This strategy is
based on its customers’ use in real life. It favors low nitrogen oxide (NOx) emissions in cities
while ensuring the best NOx/ CO2balance on open roads.
This situation undermines the group’s reputation and the interests of its 210,000 employees,
its customers and its partners. Groupe PSA reserves the right to file a complaint for breach of
confidentiality of the investigation and the authorities’ confidentiality obligation.
Groupe PSA reaffirms that:
• It complies with regulations in every country where it operates and its vehicles have
never been equipped with software or systems making it possible to detect compliance
tests and to activate a pollutant treatment device that would be inactive during customer
use.
• It is the only car manufacturer in the world to have put in place a total transparency
approach regarding the consumption and CO2emissions of its models in real use
conditions. This approach will be extended to NOx emissions by the end of 2017. The
results of the 400 measures covering 60 models (80% of European sales)
