At the end of July, Volkswagen Golf 8 officially rolled off the production line at FAW-Volkswagen Foshan Factory. The new car is planned to be officially listed and sold in China on June 5438+ 10, with the slogan "New Digital Golf".
Although the new Volkswagen Golf 8 has been fully upgraded in appearance, interior design, platform and configuration. However, in terms of powertrain, the domestic FAW-Volkswagen Golf 8 will continue to carry the old EA2 1 1? 1.4TSI turbocharged engine; In overseas markets, the Golf 7.5 model launched several years ago has been fully upgraded with more advanced 1.5TSI technology? Evo engine. It must be said that Volkswagen's engine technology upgrade in China market is slow and backward.
Volkswagen EA2 1 1 series engine was launched on 20 1 1, which is based on Volkswagen EA 1 1 series engine. The birth of EA2 1 1 series engines is due to the increasingly strict emission regulations for fuel vehicles in the European Union and the miniaturization trend of engines. EA2 1 1 series engines are divided into two specifications: naturally aspirated and turbocharged. In terms of displacement, naturally aspirated engines are: 1.0L, 1.4L, 1.5L,1.6l; Turbocharged models are: 1.0TSI, 1.2TSI,1.4 TSI; ; EA2 1 1 series engines are widely used in domestic models of Volkswagen Group, including Audi, Volkswagen and Skoda brands. Among them, 1.4TSI engine has the highest installed capacity, and 1.2TSI has a small number of vehicle applications. Some low-profile models of Volkswagen and Skoda brands use 1.5L and 1.6L naturally aspirated engines.
With the increasing requirements of global automobile emission regulations, the performance of the first generation EA2 1 1 series engines has been difficult to meet the needs of Volkswagen Group. So in 20 16, Volkswagen Group launched the second generation EA2 1 1? Evo series engines.
EA2 1 1？ Evo series engines have decreased in product specifications, and naturally aspirated engines only retain two kinds of displacement: 1.0L and 1.5L; Turbocharged engines are 1.0T and 1.5t ... where 1.5TSI? Evo engine is the most widely used model, which was first assembled on Golf 7.5, Audi A3 and other models.
Compared with EA2 1 1, which one is still widely used in China? 1.4TSI engine, second generation EA2 1 1? Evo series 1.5? TSI？ Evo engine performance has been fully upgraded. In terms of specific technical details, Volkswagen 1.5? TSI？ Evo engine adopts Miller cycle, equipped with VTG variable geometry section turbine technology, 350bar direct injection system, 12.5: 1 high compression ratio, APS coating and ACT cylinder closing technology; This makes its thermal efficiency as high as 37.5%, which is more than 1.4TSI.
Although in the calibration of maximum power output, 1.5? TSI？ Evo engine and 1.4TSI are both 150 horsepower, but in terms of fuel consumption performance, the comprehensive fuel consumption of its high-power version is only 4.6L per 100 kilometers; Compared with the comprehensive fuel consumption performance of 1.4TSI high-power version of 5.4L, it can save more than 10% of fuel on the same vehicle. More importantly, 1.5? TSI？ Evo engine can also meet stricter emission regulations and standards, and has higher reliability. Of course, this also brings higher production cost and more complicated structure. So the public delayed adding 1.5? TSI？ Evo engine was introduced into China market, and a large part of the reason may also be related to the high production cost. After all, 1.4TSI and 1.5TSI seem to have no difference in power data.
However, according to the news that has been exposed before, does Volkswagen still have 1.5? TSI？ Evo engine is planned to be made in China. According to the news, FAW-Volkswagen has put on record the opening of the Chengdu factory in the Development and Reform Bureau of Longquanyi District, Chengdu, Sichuan Province on August 7, 20 19. Evo engine technical transformation project. 1.5TSI? The annual output of Evo engines will reach 600,000 units, which will be produced in three shifts. The new engine will be the first to be applied to two new SUV models, FAW-Volkswagen and Jetta. Therefore, it is reported that domestic golf 8 will not be equipped with 1.5TSI until 2023? The Evo engine also makes sense.
In addition, domestic 1.5? TSI？ Compared with the overseas version, the compression ratio of Evo engine will be lowered to 1 1.5: 1, which is expected to be related to the domestic oil quality. In addition, performance, domestic 1.5? TSI？ The maximum power output of the Evo engine will be 160 HP and the peak torque will be 250 nm, which may mean that the domestic engine is 1.5? TSI？ Evo engine may be a new GEN.2, Eurocode 1.5? TSI？ The maximum power output of Evo engine is divided into 96kw and 1 10kw, and there are low-power and high-power versions.
In recent years, while introducing new products, major manufacturers have also upgraded their power systems very quickly. In the China market, the three giants of Japanese brands: Toyota, Honda and Nissan have introduced the latest powertrain configuration in the latest domestic replacement models; Even small brands like Mazda have introduced the latest power technology into domestic production. In contrast, SAIC-GM's three-cylinder strategy in China market and Volkswagen's constant 1.4TSI engine in China seem to lag behind a lot. In terms of sales volume, Japanese cars rose again after the epidemic this year, and China consumers became more mature with the development of the market.
