| 3.0L TFSI V6 | 18 | 23 | 20 |
| 4.0L TFSI V8 | 15 | 21 | 17 |
| 3.0L TDI V6 | 22 | 27 | 24 |
As the table shows, the 3.0L TDI V6 diesel engine offers the best fuel efficiency, with an estimated 24 mpg combined. The 3.0L TFSI V6 gasoline engine also delivers respectable efficiency, while the powerful 4.0L TFSI V8 understandably has the lowest fuel economy numbers.
The Audi Q8 leverages several advanced technologies to enhance its performance and efficiency.
The 3.0L TDI V6 engine is equipped with Audi’s Mild Hybrid System, which uses a 48-volt electrical system and a belt-driven alternator-starter to provide additional power and efficiency benefits. This system can recover energy during deceleration and coasting, and use it to assist the engine, reducing fuel consumption and emissions.
All Audi Q8 models come standard with the brand’s renowned Quattro all-wheel-drive system. This advanced system continuously monitors traction and distributes power to the wheels with the most grip, providing exceptional handling and stability in a wide range of driving conditions.
What is the difference between the 3.0L TFSI V6 and the 4.0L TFSI V8 engines? The 4.0L TFSI V8 engine offers significantly more power and torque compared to the 3.0L TFSI V6, with 500 hp and 568 lb-ft of torque versus 335 hp and 369 lb-ft. This translates to quicker acceleration and a higher top speed, but at the expense of lower fuel efficiency.
How does the 3.0L TDI V6 diesel engine perform compared to the gasoline options? The 3.0L TDI V6 diesel engine delivers a compelling balance of performance and efficiency. While it has slightly lower horsepower than the 3.0L TFSI V6, the diesel’s abundant torque provides excellent low-end power and towing capability. Additionally, the 3.0L TDI V6 offers the best fuel economy of the three engine options.
What is the Mild Hybrid System, and how does it benefit the Audi Q8? The Mild Hybrid System in the 3.0L TDI V6 engine uses a 48-volt electrical system and a belt-driven alternator-starter to recover energy during deceleration and coasting. This energy is then used to assist the engine, reducing fuel consumption and emissions, while also providing a smoother start-stop function.
How does the Quattro all-wheel-drive system enhance the Audi Q8’s performance? The Quattro all-wheel-drive system continuously monitors traction and distributes power to the wheels with the most grip. This ensures exceptional handling and stability in a wide range of driving conditions, from dry pavement to slippery surfaces, providing the driver with a confident and secure driving experience.
What are the key differences in performance and efficiency between the gasoline and diesel engine options? The 4.0L TFSI V8 gasoline engine offers the highest performance, with blistering acceleration and a higher top speed, but lower fuel efficiency. The 3.0L TFSI V6 gasoline engine provides a balance of performance and efficiency, while the 3.0L TDI V6 diesel engine prioritizes efficiency, with the best fuel economy numbers, but slightly lower horsepower.
The Audi Q8 offers a diverse engine lineup that caters to a wide range of luxury SUV buyers. Whether you prioritize performance, efficiency, or a balance of both, there’s an engine option in the Q8 lineup that will meet your needs.
