Powered by an enhanced 3.0-litre TFSI V6 turbocharged engine, the SQ5 generates an exhilarating 349 horsepower and 500 Nm of torque. This substantial power increase enables the SQ5 to accelerate from 0 to 100 km/h in just 4.7 seconds. The SQ5 also features a sport-tuned suspension with adaptive dampers, larger brakes, and a more responsive steering system, creating a more engaging driving experience. Despite its performance credentials, the SQ5 maintains reasonable efficiency with a combined rating of approximately 10.2 L/100 km.
How Has Audi Improved the Q5 Plug-in Hybrid Option?
The Q5 TFSI e represents the latest Audi advancement in plug-in hybrid technology. This sophisticated system combines the 2.0-litre TFSI engine with a powerful electric motor integrated into the transmission housing. Together, they produce a combined output of 362 horsepower and 500 Nm of torque. A larger 17.9 kWh lithium-ion battery pack enables an electric-only range of approximately 61 kilometres, making emissions-free daily commuting a practical reality. The TFSI e model achieves a remarkable combined fuel consumption rating of just 2.5 L/100 km when utilizing both power sources optimally and can reach 100 km/h in approximately 5.3 seconds, demonstrating that efficiency need not come at the expense of performance.
What Transmission Options Complement These Engines?
Across the Q5 lineup, Audi has refined its transmission offerings to maximize both performance and efficiency. The standard 2.0-litre TFSI and SQ5 models feature an advanced 8-speed tiptronic automatic transmission that delivers smooth, quick shifts. This transmission offers multiple driving modes, including a dynamic setting that holds gears longer and provides more aggressive downshifts. The TFSI e plug-in hybrid utilizes a specialized 7-speed S tronic dual-clutch transmission that has been engineered to work seamlessly with the hybrid powertrain, allowing for instantaneous power delivery and efficient energy management between the combustion engine and electric motor.
What Technological Advancements Support the Q5 Engine Performance?
The Q5 incorporates several technological innovations that enhance its engine performance. The latest Audi engine management system continuously optimizes combustion processes, adjusting parameters in real-time to balance power, efficiency, and emissions. The integrated drive select system allows drivers to customize the powertrain’s response characteristics, adjusting throttle sensitivity, shift points, and even exhaust note in the SQ5. Additionally, advanced thermal management systems ensure optimal operating temperatures are reached quickly, reducing fuel consumption and emissions during cold starts. The quattro all-wheel drive system now features intelligent torque vectoring capabilities, enhancing handling by distributing power precisely to the wheels with the most traction.
How Does the Q5 Cooling System Handle Varied Driving Conditions?
Recognizing that thermal management is crucial for both performance and longevity, Audi has implemented an advanced cooling system in the Q5. The system features multiple cooling circuits with electronically controlled pumps that operate only when needed, reducing parasitic power losses. In the TFSI e model, a sophisticated liquid cooling system maintains the battery pack at optimal temperatures, preserving its capacity and extending its lifespan. During spirited driving or when towing, the system can increase cooling capacity to prevent performance degradation, while in less demanding situations, it prioritizes efficiency by minimizing energy consumption.
What Efficiency Features Help Reduce Fuel Consumption?
The Q5 incorporates numerous efficiency-enhancing features across its engine lineup. Start-stop technology seamlessly shuts off the engine at idle, reducing fuel consumption in urban driving. Cylinder deactivation technology in the V6 engine allows it to run on four cylinders under light loads, significantly improving efficiency without noticeable transitions. The Q5 also benefits from enhanced aerodynamics, with active grille shutters that close at higher speeds to reduce drag. In the hybrid models, predictive efficiency assist uses navigation data to anticipate upcoming driving situations, intelligently managing the powertrain to optimize energy usage based on the route ahead.
What Emissions Standards Do the 2025 Q5 Engines Meet?
All Q5 engines meet and exceed stringent emissions standards. Advanced catalytic converters and particulate filters reduce harmful pollutants, while precise fuel injection systems minimize unburned hydrocarbons. The mild hybrid and plug-in hybrid systems contribute significantly to lowering overall emissions by reducing the engine’s workload and enabling electric-only operation in urban environments. The result is a lineup of engines that achieves a balance between performance, efficiency, and environmental responsibility, with CO2 emissions ranging from as low as 56 g/km for the TFSI e model to approximately 198 g/km for the performance-oriented SQ5.
5 Facts About the 2025 Audi Q5 Engine Options

All engines require premium fuel (91 octane or higher). While they can run on regular fuel if necessary, premium fuel achieves the specified performance and efficiency figures.
How does the quattro all-wheel drive system differ between the various Q5 models?
-
The standard model features quattro with ultra technology, which can disconnect the rear axle during steady cruising for improved efficiency. The SQ5 uses a more performance-oriented quattro system with a default 40:60 front-to-rear torque split and the ability to send up to 85% of power to the rear wheels. The TFSI e model incorporates a specially calibrated quattro system that integrates with the hybrid powertrain.
Are there any special maintenance requirements for the Q5 TFSI e plug-in hybrid?
-
It requires similar maintenance to other models for its combustion engine components. However, it has additional service points related to the high-voltage system that you should inspect regularly. The battery system should be maintenance-free throughout the vehicle’s lifetime under normal usage conditions.
How does the SQ5 engine compare to the previous generation?
-
The 3.0-litre V6 produces 20 more horsepower and 30 more Nm of torque than its predecessor, while also improving fuel efficiency by approximately 7%. The new engine also responds more quickly to throttle inputs thanks to a revised turbocharger with lighter turbine components.
Can the Q5 TFSI e maintain its battery charge while driving?
-
Yes, it offers a “Hold” mode that maintains the current battery charge level by primarily using the combustion engine. There is also a “Charge” mode that uses the engine to actively recharge the battery while driving, though this is less efficient than plug-in charging.
What is the expected lifespan of the 48-volt battery in the mild hybrid system?
-
The lithium-ion battery used in the 48-volt mild hybrid system should last the lifetime of the vehicle. It operates within a specific charge window (never fully charged or depleted) to maximize longevity, and its performance is continuously monitored by the vehicle’s diagnostic systems.
How does the Q5 engine start-stop system differ from earlier versions?
-
The enhanced start-stop system can shut off the engine while the vehicle is still moving at low speeds (below 22 km/h) when approaching a stop. The 48-volt system enables smoother, faster restarts with less vibration, and can keep comfort systems running longer with the engine off, improving both the driving experience and fuel efficiency.
