Audi presents its innovative MHEV plus thermal engines in the recent A5 and Q5 lines
With the presentation of the innovative MHEV Plus thermal engines, Audi has made a significant milestone in its commitment to electrification and sustainability. The latest A5 and Q5 series, built on the Premium Combustion Platform (PCP), incorporate this 48-volt mild hybridization technology, designed to enhance the efficiency of internal combustion engines, reduce carbon emissions, and provide a more comfortable and dynamic driving experience. By combining a propulsion system generator (PTG), a belt-driven starter generator (BAS), and a lithium iron phosphate battery, the MHEV plus system represents a step towards the future of efficient hybrid vehicles.
With the introduction of MHEV plus technology in the new A5 and Q5 series, Audi reaffirms its commitment to the efficient electrification of its thermal engines. This advancement focuses on improving performance and reducing carbon emissions, thanks to a mild hybridization system that emphasizes a more agile and comfortable driving experience.
A New Step in Electrification: MHEV Plus Technology
The new A5 and Q5 series from Audi, built on the Premium Combustion Platform (PCP), incorporate thermal engines with MHEV plus technology for the first time. This innovative technological solution supports the exclusive interaction between the propulsion system generator (PTG), the belt-driven starter generator (BAS), and a lithium iron phosphate battery (LFP), enhancing the performance of the combustion engine while reducing carbon emissions.
Components of the MHEV Plus System
Audi’s 48-volt mild hybridization system consists of three main components: the generator integrated into the propulsion system (PTG), a permanent magnet synchronous motor, and a 48-volt battery connected to a belt-driven starter generator (BAS). The battery capacity of 37 Ah, along with the power of 24 kW, ensures optimal conditions for efficient performance.
Benefits of Partially Electric Driving
The architecture of the MHEV plus system allows for purely electric driving in certain situations, which translates not only into lower fuel consumption but also significantly improves driving comfort. The reduction in CO2 emissions is achieved thanks to the additional support provided by the electric motor to the combustion engine.
Innovation in the Powertrain Generator (PTG) Design
The powertrain generator (PTG) is the most notable innovation of the MHEV plus system. This generator can deliver up to 18 kW of electric power and a maximum torque of 230 Nm, allowing for high efficiency up to 140 km/h. This powerful module can be used both in front-wheel and all-wheel drive vehicles without the need for complex structural modifications.
Improved Performance and Efficiency
The placement of the PTG directly behind the transmission maximizes the utilization of generated power, minimizing losses during the transmission process. Additionally, the BAS system allows for energy recovery during deceleration and optimizes the starting of the combustion engine, enhancing the driving experience.
The Role of the LFP Battery and the iBRS Brake Control System
For the first time, Audi uses a lithium iron phosphate battery in its mild hybridization system, ensuring optimal durability and efficiency. Along with this, the iBRS system enables efficient regenerative braking without relying exclusively on the hydraulic brake system, thus ensuring a natural and precise feel.
Audi’s Advances in Mild Hybridization
Audi has taken a bold step towards the future of sustainable motoring with the introduction of its MHEV plus thermal engines in the A5 and Q5 models. Built on the Premium Combustion Platform, these vehicles integrate innovative technology that combines efficiency, performance, and sustainability.
The key to MHEV plus lies in its ability to use a 48-volt mild hybridization system, which assists the traditional combustion engine through a unique interaction of innovative components such as the powertrain generator (PTG) and the lithium iron phosphate battery. This technological development not only reduces carbon emissions but also provides an increase in vehicle agility and comfort, significantly enhancing the driving experience.
The performance of this system is optimized through liquid cooling specific to each component, allowing it to operate under optimal conditions. The inclusion of the LFP battery is noteworthy as Audi uses it for the first time, placing the brand at the forefront of automotive technology by incorporating an efficient form of energy storage and release.
Additionally, the integration of the regenerative brake control system iBRS in the MHEV plus models further emphasizes Audi’s commitment to energy efficiency. This system allows for braking with minimal pressure on the pedal, relying on regenerative braking, effectively integrating the needs for power and torque.
In summary, MHEV plus engines represent a significant advancement in the automotive industry, once again demonstrating Audi’s commitment to innovation and sustainability. This approach not only addresses current environmental demands but also preserves the driving pleasure characteristic of the brand, forming a bridge to a future where combustion and electric vehicles can coexist harmoniously. Thus, Audi reaffirms its leadership by introducing technological solutions that are both environmentally friendly and appealing to the modern consumer.
