According to foreign media reports, Volkswagen Brand R&D Director Frank Welsch revealed to the European Automotive News that the Volkswagen brand 48V mild hybrid technology is currently under development, and the first model equipped with the power system is similar in size to the golf series. It is said that this technology will be carried in more models soon. The outside world believes that the most likely model to be equipped with a 48V light hybrid system is Volkswagen's new T-Roc SUV, which is expected to be launched at the end of the year and positioned below Tiguan.
Welsch said at the launch of Volkswagen's new Polo: "If this technology is used in a model based on the MQB platform, the car will be more or less plug-and-play, given that Volkswagen already has a modular platform. We also plan to carry this technology in other models."
The models produced by the Volkswagen MQB platform include the sixth-generation Polo minicars that were launched in Europe this fall, as well as the compact golf hatchback and Tiguan SUV, Skoda Octavia and Seat Leon.
In view of the resistance of diesel vehicles due to the emission of nitrogen oxides, all major car companies hope to adopt the 48V mild hybrid system to achieve the goal of energy saving and environmental protection. Renault also plans to carry this technology in the newly launched Scenic minivan.
Since major European cities are considering whether to ban the sale of diesel vehicles due to environmental requirements, the Volkswagen Group is considering whether to introduce alternatives to diesel vehicles. Since the outbreak of the emissions door in September 2015, consumer resistance to diesel vehicles has been rampant, and Volkswagen Group has also recalled 11 million diesel vehicles worldwide.
Another factor in the resistance of diesel vehicles is the need to add expensive selective catalytic reduction (SCR) to diesel vehicles to meet the increasingly stringent emission regulations. Volkswagen is now in the new Polo 1.5-liter diesel engine. SCR is added to it, and SCR also increases the cost per vehicle by about 200 Euros.
At the beginning of the year, Welsch revealed to the British Autocar magazine that the Polo diesel version of the diesel system costs about 25% of the cost of the entire vehicle, while the post-processing system used in the diesel car adds an additional $600 to $800 in material costs. But this is a tough choice for the public, and it is expected that the diesel version of the Volkswagen Polo will account for 15% of Polo's global sales. Volkswagen wants to introduce the 1.5-liter pressure common rail diesel version of the Polo, but compared to the EA827 1.6-liter turbocharged diesel engine, the research and development costs are much higher. Based on this, Volkswagen plans to take the light plug-in hybrid technology route.
Car and Driver News said in the report that Volkswagen will continue to develop the large and more commonly used EA288 2.0-liter turbocharged engine, which will be used in various models of the Volkswagen Group.
When asked if golf would become Volkswagen's first model with a 48V mild hybrid system, Welsch said: "When developing these technologies, it is not very important which car will be first loaded. We need to do it first. The good thing is the technology itself, then consider which car will be used in which car and which market it will be promoted, and we are still in the process of research and development, but it is certain that this technology will be launched soon."
