    Nova gama Mazda2, adeus ao diesel e à carroçaria de 3 portas

    El pequeño Mazda2 acaba de recibir una re-estructuración de la gama para el mercado español, reduciendo la oferta de versiones. Lo más destacable es que dejan de estar a la venta tanto la carrocería de tres puertas como las unidades con el motor 1.6 CRTD de 90 CV, dejando únicamente a los bloques de gasolina todo el protagonismo.

    A partir de ahora la oferta se centra en los niveles de acabado Style,Style y Sportive, además de la serie limitada Iruka que añade más equipamiento por un suplemento muy reducido. En cuanto a los motores, los interesados sólo encontrarán el pequeño 1.3i 16v de 75 CV, siempre con cambio manual de cinco velocidades, y el 1.5i 16v de 102 CV, este disponible tanto con caja manual de cinco relaciones como con una automática de cuatro.

    El equipamiento de serie principal en todas las versiones incluye el ABS, EBD, airbags frontales y laterales, aire acondicionado, elevalunas eléctricos, espejos plegables, radio CD MP3, USB, paragolpes pintados, llantas de aleación y asiento posterior abatible. Los Style+ añaden el climatizador automático, cargador de CDs y volante multifunción mientras que el Sportive añade el kit estético exterior, llantas de aleación de 16 pulgadas, sensor de lluvia, sistema de entrada sin llave y asientos deportivos. La serie especial Iruka también incluye el navegador, pintura metalizada, spoiler trasero y los cristales tintados entre otras cosas.

      Tendo em conta o tópico que tinha criado, ainda estava À espera de alguma novidade no campo das motorizações para o pequeno 2.

      Parece que é só mesmo reorganização da gama.
      Mas essa re-estruturação é apenas para Espanha ou irá expandir-se pelos restantes mercados?

      Abandonar diesel neste segmento é considerado algo de doidos
      Será que o 2 diesel em Espanha não vendia nada?

        Só deve abandonar o diesel porque os motores não são deles.
        Os motores apareceram quando a Ford ainda tinha uma boa participação na Mazda entretanto deixou de ter, não há sinergias nem partilha de componentes, bye bye motores diesel.

        É um pouco como o Colt, enquanto houve Forfour tinham o 1.5DID. A Mercedes desistiu do Forfour, adeus diesel.

          Também partilho desse ponto de vista.
          Aliás a Mazda está a apostar no seu próprio motor diesel 2.0, em detrimento dos motores da parceira com a Ford.
          Portanto acredito que seja mais pela falta do diesel de baixa cilindrada, do que por uma aposta clara nos motores a gasolina.

            O Mazda 2 da minha ex-namorada, 1.3 a gasolina, também andava com uma média global parecida.

            9.7 Litros / 100 km em 15 mil km.
            Quase isso deve de gastar o Mazda 6 MPS.

              A Ford ainda mantém uma pequena presença como accionista na Mazda, de cerca de 2%, ou qualquer coisa assim.
              Não nos esqueçamos que o 2 e o Fiesta, debaixo da pele, são "irmãos", tendo nascido ambos sobre a mesma base.
              Pode ser mesmo questão de disponibilidade por parte da Ford, ou as vendas do 2 diesel serem tão baixas que não justifiquem a presença de tal motor no mercado (e a notícia refere-se apenas a espanha, não sei como será nos outros países)
              Não tou a ver porque a Ford deixaria de fornecer motores à Mazda. Ganhava a Ford e a Mazda, e o 2 dificilmente ameaça a carreira do Fiesta.

              Skyactive diesel abaixo dos 2.2 já foi falado, e provavelmente só deverá aparecer com o novo 3.

                Não faz sentido que seja por outro motivo, alias, a Mazda anda bastante sensivel à questão diesel com 5x mais solicitações deste tipo de motores.

                No exemplo que referi acima o Smart e o Mitsubishi são virtualmente o mesmo carro, mesma fábrica e até as linhas de produção de ambos se cruzavam, na frente ia um Forfour e atrás um podia vir um Colt ou vice versa. A MB pelas fracas vendas desistiu do F4 e decidiu deixar de fornecer o motor para a Mitsubishi. Ora se o motor nem serve para mais nenhum modelo neste caso então é que não há qualquer tipo de ameaça para a MB, aparentemente só tinham a ganhar, aparentemente, mas não isso que decidiram.

                Mas será que o adeus ao diesel será só para alguns mercados?
                Caso se confirme, obviamente que é pela questão das poucas vendas.

                      Mazda Skyactiv-D engine for racing.


                      "Mazda didn’t say so specifically, but it appears the problems with its Skyactiv-D clean-diesel engine stem from the company’s attempts to skirt the costs and complexities of the kind of emissions-cleansing system that is found in most other companies’ modern-era diesel engines.

                      The company just announced that it is delaying the Skyactiv-D for the second time, backing away from a planned late-spring deployment in the Mazda6 sedan in the U.S. market. Mazda didn’t specify a new deadline.

                      But Mazda did say that “further development is required to deliver the right balance between fuel economy and Mazda-appropriate driving performance.” And the company hinted that its difficulties may have to do with nitrogen-oxide (NOx) emissions in its release about the delay, noting, “Mazda understands its Skyactiv-D can meet emission-regulation requirements without the use of a NOx after-treatment system.”

                      So it seems that the difficulties Mazda is facing in getting this engine to market may have directly to do with one of the most revolutionary features of Skyactiv-D, centered specifically around emissions scrubbing.

                      “Diesel-engine designers have long grappled with a dilemma: Reducing emissions meant either cutting efficiency or adding expensive equipment,” Popular BPOP +3.33% Science observed in an article last March in which it suggested that Mazda had “reinvented the diesel engine” with Skyactiv-D.

                      “With the Skyactiv-D, Mazda engineers decreased pollution, boosted mileage, and eliminated the cost of exhaust after-treatments by building the world’s lowest-compression diesel engine,” the magazine explained.

                      Popular Science said that this “low compression ratio cuts emissions of nitrogen oxide and other pollutants enough to meet present (and future) standards both in Europe and the U.S. As a result, the Mazda6 does away with expensive urea tanks (which drivers have to refill every 10,000 miles or so) that many diesels use to neutralize emissions.”

                      But avoiding the challenges posed by using the conventional NOx-reducing system makes it more of a challenge for Mazda to tune the engine’s throttle response and other characteristics so that excessive emissions aren’t produced in certain driving situations. To avoid using the urea-injection system, Mazda can cut back on performance or fuel economy — specifically including reducing the compression ratio — but at this point the automaker said it hasn’t yet achieved a satisfactory balance in that area."

                      Skyactiv-D Delay May Reflect Mazda Tack On NOx Emissions

                        "While Mazda’s 2.2-liter Skyactiv-D diesel four-cylinder remains in development for the U.S. market—it’ll eventually launch in the Mazda 6 sedan—the automaker has released some neat technical details about its new smaller diesel. The engine displaces just 1.5 liters but shares the Skyactiv-D moniker. It’s headed for the Japanese and European markets, where it will power the next-generation Mazda 2, previewed by the hot Hazumi concept shown here.

                        Skyactiv is the marketing name for Mazda’s weight-shaving and fuel-economy-enhancing technologies, and it has been applied to everything from engines and transmissions to entire body structures. In the case of the 1.5-liter Skyactiv-D, it adds “clean emissions” to that repertoire. Mazda claims the little diesel will sail through Euro 6 and Japanese emissions certification, and that it will do so without the aid of cost-adding NOx after-treatment systems such as urea injection.



                        To clean up the engine, Mazda applied an aggressive regimen of combustion temperature–reducing measures like high- and low-pressure exhaust-gas recirculation systems (the exhaust replaces some oxygen into the combustion chamber, reducing heat and limiting NOx production), high-dispersion fuel injectors and dished pistons, an air-to-water intercooler, water jacket spacers that concentrate more coolant flow toward the head, and a low 14.8:1 compression ratio. In the Mazda 2, the clean-burning engine also will be paired with Mazda’s fuel-saving i-ELOOP brake-energy recuperation and engine stop-start technologies.

                        Despite its low emissions, the 1.5-liter Skyactiv-D makes decent grunt, pumping out 103 horsepower and 184 lb-ft of torque. Suffice it to say, when bolted into a light vehicle like the 2, that’s should be plenty—consider that the current Mazda 2‘s gas-fed 1.5-liter four puts down a measly 100 horsepower and 98 lb-ft of torque and is still fun to drive. With nearly twice as much torque—available as low as 1500 rpm—the Skyactiv could take the 2 to a whole new level. Interestingly, Mazda points out in its press materials for the new engine that the diesel’s torque output matches up to that of its 2.5-liter gas four, which is found in everything from the Mazda 3 to the CX-5. We don’t see why Mazda couldn’t drop the 1.5-liter into, say, the 3 and instantly create an adversary for Ford’s 1.0-liter EcoBoost-equipped Focus.

                        While Japan and Europe are definitely getting the new diesel, there’s no word of a U.S. version. That’s probably not an accident, given the issues Mazda’s having here with the larger 2.2-liter Skyactiv-D. From what we’ve gathered, Mazda could meet emissions in the states with the 2.2-liter even without exhaust after-treatment, but that it isn’t satisfied with the engine’s drivability. (Thereby implying that tuning changes to achieve the desired character compromises emissions compliance.) Given that, we’re not holding our breath for a stateside arrival anytime soon."

                                  "TOKYO (Bloomberg) -- Japan’s transport ministry has ordered carmakers to investigate whether their diesel vehicles meet the country’s emission norms after Volkswagen AG’s admitted to rigging some cars to cheat on U.S. tests.

                                  The ministry has asked carmakers including Toyota Motor Corp., Mazda Motor Corp. and Volkswagen to submit reports of their probes by the end of this week, Transport Minister Akihiro Ohta told reporters in Tokyo today. The government is considering changing the method it uses to test diesel engines, Ohta said, without being more specific.

                                  Japan joins South Korea, France and the U.K. among countries investigating compliance by carmakers after Volkswagen’s revelation that it used software that obfuscates how much its diesel-engine cars pollute
                                  . It led to the carmaker’s former CEO Martin Winterkorn stepping down and the company’s market value plunging 27 billion euros ($30.4 billion).

                                  The German automaker doesn’t sell diesel cars through its official dealer networks in Japan, but individual buyers have imported about 230 Volkswagen and Audi cars since 2008, according to Ohta. The ministry is checking whether these vehicles need to be recalled and fixed.

                                  Volkswagen, the best-selling foreign brand in Japan last year, is working with authorities and is monitoring the impact on its brand image and sales, Hiromu Hatanaka, a Tokyo-based spokesman of the company, said by phone.

                                  Mazda, the carmaker that sells the most diesel cars in Japan, said every gasoline and diesel engine it makes fully comply with the regulations of the countries in which they are sold, and it “never uses illegal software or defeat devices,” according to a company statement Tuesday.

                                  Mitsubishi Motors Corp. said it has received the order from the ministry and will submit its report as asked. BMW does not “manipulate or rig” any emission tests, and meets legal and testing requirements in each country, it said in an emailed response. Toyota and Nissan didn’t immediately respond to emails and phone calls seeking comment."

                                    TOKYO (Bloomberg) -- Mazda Motor Corp.’s plans to introduce a diesel car in its most important market risk falling further behind schedule after Volkswagen AG flouted U.S. rules and unleashed global regulatory scrutiny on the technology.

                                    The cloudy outlook for Mazda’s U.S. diesel ambitions stands out as an example of collateral damage from VW's cheating on U.S. emissions tests. Revelations that the German company achieved its promise of “clean diesel” by using software to beat laboratory tests not only sullied consumer perception of the cars, they also cast doubt on Mazda’s ability to create an engine that’s both fuel efficient and clean.

                                    “It’s been delayed and delayed, and Mazda keeps saying it’s coming,” Dave Sullivan, an analyst for industry researcher AutoPacific Inc., said by phone. “At this point, I don’t understand why they would need a diesel for this market. I don’t see it happening.”

                                    Mazda’s engineers are trying to develop the Skyactiv-D engine in line with U.S. emissions standards without sacrificing performance, said Michiko Terashima, a company spokeswoman. The company doesn’t have a time frame for introducing the engine but won’t change its plan because of the Volkswagen case, she said.

                                    Diesel reliance

                                    Mazda is the Japanese carmaker most reliant on diesel, with about 45 percent of its domestic sales from diesel models in the quarter through June. By contrast, Toyota Motor Corp. and Nissan Motor Co. have prioritized hybrids and electric vehicles, respectively.

                                    Volkswagen disclosed last month that it sold as many as 11 million vehicles worldwide with diesel engines using software that limits full pollution controls to when the car’s emissions are being tested. In normal driving, the cars pollute 10 times to 40 times more than legal limits, according to the U.S. Environmental Protection Agency.

                                    “Mazda is aiming to introduce the diesel vehicles in North America, but this Volkswagen cheating case looms dark in front,” Satoru Takada, an analyst at TIW Inc. in Tokyo, said by phone. “There is the possibility that authorities raise the bar of emissions testing even higher. That would be a burden for their strategy.”

                                    Mazda had aimed to bring a Mazda6 diesel model to the U.S. in 2013. While it’s not for sale in the country, the company still promotes the Skyactiv-D engine on its U.S. website with a video that declares they’ve come a long way since Rudolf Diesel invented them in 1893.

                                    ‘Cleaner than ever’

                                    “No longer sooty, clattering workhorses, today’s diesel engines are quiet, durable and cleaner than ever,” the video says.

                                    Mazda notes that diesel’s compromises have included the need for heavy, industrial-strength parts that sap driving performance because the engines run with higher combustion pressures. Cleaning up their nitrogen oxide emissions often necessitates costly after-treatment systems.

                                    The EPA has alleged that Volkswagen overcame these issues using a “defeat device.” Mazda claims in its video that Skyactiv-D’s workaround was to lower compression ratios, delay combustion and give fuel and air a millisecond more time to mix, reducing pollutants.

                                    “When we were done, we had created a beast,” the video says, promising customers the driving performance of a larger gasoline engines and the fuel economy of a hybrid. “With such dramatic improvements, Mr. Diesel himself might not recognize it, but no doubt, he’d love to drive it.”

                                    Mazda never uses illegal software of “defeat devices” to comply with emissions regulations, the company said Tuesday in an e-mailed statement. The carmaker said it supports countries around the world that are investigating new testing methods based on real-world driving conditions.

                                    Volkswagen’s deception will make make it harder for Mazda as the U.S. government was already withholding support for diesel engines, AutoPacific’s Sullivan said.

                                    “The government is not making it easy, and if anything it’s just going to get worse,” he said. “The oversight that’s coming is about to make it even more difficult.”"

                                    Mazda’s diesel dreams for U.S. in doubt after VW scandal

                                      As ondas de choque da fraude da VW irão fazer-se sentir durante os próximos meses e anos.
                                      O investimento e tempo que a Mazda tem dedicado a introduzir uma motorização diesel nos EUA, talvez devesse ser ponderado e talvez partir para outra solução.
                                      É provável que o esforço de expandir o uso de diesel em carros ligeiros nos EUA tenha sido mandado completamente às urtigas com a fraude da VW.
                                      Quanto muito, vejo apenas pick-ups e alguns SUV's onde o diesel poderá ainda ter uma palavra a dizer por aqueles lados.

                                        A Mazda não avançou de imediato pela questão das emissões poluentes máximas exigidas versus dinâmica dada pela mecânica, pelo que leio a tecnologia Skyactiv-D apresenta uma série de questão no seu funcionamento que lhe dá vantagem sobre a concorrência na manutenção a prazo para cumprir norma europeia anti-poluição (Euro 6).

                                        O mercado diesel da América do Norte é residual, a questão de fundo é a base industrial da Mazda em mecânica diesel na Ásia que lhe iria permitir ter retorno no nicho de mercado norte-americano a diesel em familiar médio (6), e SUV (CX-5 e CX-3).

                                        Aponto pelo que leio para oportunidade única para carro a gás natural e híbrido, coisa já muito avançada na Europa e Ásia e com forte apoio federal do EUA (via questão petrolífera), e de investimento industrial maciço de marcas como a Ford, GM, VW, MB neste particular.
