migueldosantos77 Posted October 12, 2023 Share Posted October 12, 2023 It is widely acknowledged that Volkswagen has been responsible for significant and reprehensible issues, and several experts in the automotive industry have suggested that other manufacturers may also be implicated in similar practices. I have just obtained a Mazda Venture Sport 1.6 diesel vehicle, marking my second acquisition of this particular model. I have a genuine belief that Mazda will refrain from engaging in the aforementioned reprehensible conduct. I anticipate that they will promptly declare their decision to abstain from using this approach in their diesel vehicle lineup. Quote Link to comment Share on other sites More sharing options...
WanderlustGuru Posted October 12, 2023 Share Posted October 12, 2023 The vigilant observation of these occurrences by consumers of various firms is evident. Currently, it seems that only Volkswagen and its subsidiaries have been impacted by the situation, which might be seen as positive news. It has been well recognized that the automotive industry, as a collective entity, tends to be economical with the facts in regard to fuel efficiency ratings. However, this represents a distinct and elevated degree of complexity. Similar to yourself, I have the belief that any other manufacturers engaged in unethical practices, if they exist, would duly disclose their actions in the appropriate manner.

Starcar2022 Posted October 12, 2023 Share Posted October 12, 2023 Upon examination, it was discovered that the emissions of a skyactiv Mazda 6, as reported by the press, exceeded the declared levels by a factor of four under regular use. However, it is plausible that the test protocol lacks congruity with real-world scenarios. If I were in possession of an x3 BMW, my level of restlessness would be far higher, exceeding the limit by a factor of nine. Nevertheless, it is important to distinguish between using a test that is inadequately constructed and intentionally engineering a vehicle to deceive the test and operate in a manner that is completely non-compliant under normal conditions. This is the reason why Volkswagen (VW) is now facing significant challenges, as it may potentially undergo a revised taxes and testing framework that applies universally.

honeycut_mazda5 Posted October 12, 2023 Share Posted October 12, 2023 Although Mazda had a greater decline compared to other companies, this may be attributed to the extent of their financial resources to withstand the challenges faced by the sector as a whole, including the anticipated increase in regulatory expenses. It is important to note that this does not imply a larger likelihood of Mazda engaging in any kind of misconduct. According to an unidentified source, Mazda had previously expressed intentions to introduce diesel engines to the US market in the near future. However, these plans have faced multiple delays and have currently been put on hold in order to maintain the expected performance standards that Mazda customers anticipate. In summary, it is advisable to observe with a vested interest and exercise patience. Quote Link to comment Share on other sites More sharing options...
migueldosantos77 Posted October 12, 2023 Author Share Posted October 12, 2023 I have not made any assertions on Mazda's potential involvement in cheating practices. My intention was just to provide a publicly available news piece for reference. Although my personal satisfaction with Mazda UK and its dealer network is now at its lowest point, I am optimistic that Mazda has shown integrity in this particular case and will attentively monitor the developments.

Starcar2022 Posted October 12, 2023 Share Posted October 12, 2023 I am not especially concerned for many distinct reasons. The correlation between tail pipe emissions and fuel efficiency is evident, since the reported values for my vehicle align with the testing it underwent, implying that the testing process was conducted without any manipulation, unless there is a concealed catalytic converter bypass pipe, in which case the emissions may be affected. The engine style used by Mazda does not include inherent characteristics that facilitate the generation of deceptive data. One primary rationale for using downsizing strategies is the ability to operate a compact engine without turbo boost during standard performance evaluations, hence yielding excessively impressive statistics. Once the vehicle is in motion, it is necessary to engage the turbocharger, at which juncture the efficiency becomes comparable to that of an engine with a typical size. Although the skyactiv technology does not quite align with the stated statistics, it exhibits a notable improvement in efficiency compared to Mazda's previous 2.0 engine. Users on this platform report achieving better fuel consumption results than what my 1.6 engine is capable of achieving. This implies that substantial progress has been achieved, rather than only superficial adjustments. During my experience with the Skyactiv 2 equipped with a 1.5 engine, I saw a fuel efficiency improvement of 10 miles per gallon compared to my previous 1.5 Suzuki vehicle. Remarkably, this level of efficiency was on par with our diesel Citroen model. Once again, it should be noted that the mentioned improvement pertains to real-world application rather than being a hypothetical or theoretical concept. I hope that the company in question has not used any defeat devices. In my opinion, their reported results tend to be more dependable compared to those of other manufacturers. Alternatively, one may get a greater proportion of the stated figures with more frequency. Quote Link to comment Share on other sites More sharing options...

migueldosantos77 Posted October 12, 2023 Author Share Posted October 12, 2023 As observed in an article published in the Mail on Sunday on October 4th. Volkswagen is not the only entity implicated in this matter. The report was authored by Dr. James Tate, a researcher affiliated with the Institute of Transport Studies at Leeds University. The Mercedes-Benz vehicle was found to be exceeding the speed limit by a factor of 5.3. The BMW was seen traveling at a speed that exceeded the legal limit by a factor of 5.6. The Mazda 6 exceeded the speed limit by 1.0 times. The Ford vehicle exceeded the limit by a factor of 6.8. The individual proceeds to assert that little diesel automobiles in urban areas produce more pollutants than double-decker buses or fully loaded 40-ton articulated trucks, hence presenting a significant economic opportunity for car manufacturers. This enables them to market tax-friendly, high-performance luxury vehicles that purportedly exhibit low pollution levels, hence facilitating increased profitability. On average, Mazda engines had the highest emission levels, with an average of 0.49 grams per kilometer. If we accept this premise, it is anticipated that Mazda will provide news in the near future.

Starcar2022 Posted October 12, 2023 Share Posted October 12, 2023 However, it should be noted that the product in question is not deemed unlawful since it has successfully through the necessary examinations. The act of non-compliance with emissions regulations is deemed unlawful only when vehicles are equipped with emissions control systems specifically designed to function exclusively during testing procedures, with the intention of evading detection. I would find it intriguing if super small vehicles were really achieving greater scores than buses, as opposed to my suspicion that the reported results for buses may be overstated. Furthermore, can it be attributed to the makers that the test fails to accurately depict real-world conditions? The test, which is well acknowledged to lack representativeness, has been shown to be unrepresentative. This finding does not come as a surprise, to be honest.

CelestialSeeker Posted October 12, 2023 Share Posted October 12, 2023 Naturally, vehicles that adhere to regulatory standards will not exhibit emissions levels comparable to those of inadequately engineered vehicles under a standardized testing procedure. If manufacturers adhere to the test requirements, it is possible to get a comparison that is equivalent in all aspects. This concludes the discussion. I have driven a limited number of automobiles, and in most cases, I have been able to achieve fuel efficiency ratings that are rather near to those specified by the manufacturers. However, this outcome is contingent upon using a driving style characterized by smooth and anticipatory maneuvers, while avoiding any excessive or extreme behaviors. It is important to note that emissions should not be confused with miles per gallon (mpg). When using a leaner fuel-air mixture, the fuel efficiency, measured in miles per gallon (mpg), tends to improve. However, this approach often leads to increased emissions of nitrogen oxides (NOx), so compromising the overall frugality of engines. Consequently, there exists a trade-off between fuel efficiency and emission levels in engine performance. The only problem pertains to Volkswagen's use of deceptive software, whilst other automakers' emissions versus test results remain unaffected. However, it is important to note that journalists, for the most part, do not possess scientific or technical backgrounds, which may limit their understanding of the fundamental concepts involved. Consequently, they may tend to prioritize sensationalism over accuracy, often emphasizing the most alarming aspects of a story. For instance, they could exaggerate the severity of a situation by claiming that "everyone is four times over" the acceptable limit. The observed discrepancy between real-life vehicle emissions and emission test results is unsurprising, since it aligns with expectations. However, this finding may not get much attention due to its lack of novelty. Quote Link to comment Share on other sites More sharing options...
