The Audi A5 plug-in hybrid (PHEV) models combine the performance of a traditional combustion engine with the efficiency of an electric motor. This innovative hybrid system seamlessly integrates to provide a driving experience that prioritizes both power and sustainability. Let’s delve into the technology that makes the Audi A5 PHEV a leader in its class.
Advanced Hybrid Management System in the Audi A5
The Audi A5 PHEV boasts an intelligent hybrid management system designed for optimal efficiency and driver comfort. The system automatically selects the most efficient operating strategy based on driving conditions. A permanently excited synchronous motor, integrated into the seven-speed S tronic transmission, delivers a peak output of 105 kW. Impressively, full system torque of 500 Nm (270 kW variant) or 450 Nm (220 kW variant) is available instantly, even at idle. Further enhancing efficiency, a newly developed, smaller, and lighter pulse inverter minimizes electrical consumption, contributing to lower overall fuel consumption in hybrid mode.
Enhanced Battery Capacity and Energy Density
A key component of the A5 PHEV is its high-voltage (HV) battery, strategically located at the rear of the vehicle. With a capacity of 25.9 kWh (20.7 kWh net), this battery represents a significant 45% increase compared to its predecessor. Despite the increased capacity, the battery’s physical size remains compact, measuring 992 × 996 × 177 millimeters. The interaction between the mechanical friction brake and energy recovery system has also been optimized, resulting in improved regenerative braking performance. This advanced system captures and reuses energy during braking, further enhancing efficiency.
Innovative Cell-to-Pack Battery Technology
The A5 PHEV utilizes innovative cell-to-pack technology, where prismatic battery cells are directly integrated into the battery housing, eliminating the need for traditional modules. This approach increases packing density, allowing for higher energy content and density within a smaller space. Each cell boasts a 46% increase in energy storage compared to previous generations, with a charge capacity of 70 Ah. The advanced cell chemistry also contributes to higher electrical output, even in low states of charge or cold temperatures.
Faster Charging Times for the Audi A5
Charging the A5 PHEV is now faster and more convenient. With an upgraded three-phase 11 kW AC charging system, a full charge can be achieved in just 2.5 hours. A standard mode 3, plug type 2 charging cable is included for easy charging at home or on the go. Audi also offers access to its extensive charging network, Audi charging, providing numerous AC charging points across 29 European countries.
Maximizing Energy Recovery: Regenerative Braking
The A5 PHEV maximizes energy recovery through enhanced regenerative braking. The system prioritizes electric driving and utilizes the battery charge efficiently. During deceleration, the electric motor acts as a generator, recovering up to 88 kW of power. This accounts for over 90% of all deceleration events. The integrated brake control system (iBRS) ensures seamless transitions between regenerative and hydraulic braking, providing optimal energy recovery without compromising braking feel. Drivers can even adjust the level of regenerative braking using steering wheel paddles, allowing for a customized driving experience.
Intelligent Operating Strategies for Efficiency
The A5 PHEV offers two primary operating modes: “EV” and “Hybrid.” In EV mode, the car runs solely on electric power, with the combustion engine engaging only under specific circumstances, such as kickdown or when the battery is depleted. In Hybrid mode, the system intelligently manages the battery’s state of charge, optimizing efficiency for both short and long journeys. The system considers factors like route data, speed, and driver behavior to determine the most efficient use of electric and hybrid power.
Customizable Driving Experience: Charge Level Control
Drivers can now personalize their driving experience with a new feature that allows for manual adjustment of the desired charge level. This digital slider enables drivers to specify the battery’s target state of charge, ensuring sufficient electric power for specific portions of their journey, such as city driving. This feature gives drivers greater control over energy usage and allows them to tailor the hybrid system to their individual needs.
Conclusion: The Audi A5 – A Leader in Hybrid Technology
The Audi A5 PHEV represents a significant advancement in hybrid technology, combining performance and efficiency with innovative features that enhance the driving experience. With its intelligent hybrid management system, increased battery capacity, faster charging times, and customizable driving modes, the A5 PHEV sets a new standard for sustainable performance in the luxury vehicle segment. It offers a compelling solution for drivers seeking a powerful yet environmentally conscious vehicle.
