Audi Q7 vs. Audi Q8: A Complete 2025 Comparison

The Audi Q7 has long been the benchmark for a spacious and luxurious family SUV, offering room for up to seven passengers and uncompromising practicality in its generous interior. It is challenged by the Audi Q8, which presents a more emotive and sportier SUV-coupé style alternative, focusing primarily on bold design and more dynamic driving characteristics. Although both cars share a technical foundation, their characters are so different that they deserve a detailed comparison to help you discover which one is right for you.

Exterior Dimensions: Family Space vs. Sporty Stance

Although the Audi Q7 and Q8 share the same technical platform, their exterior dimensions clearly reveal their different focuses. While the Q7 maximises interior space and practicality, the Q8 opts for a dynamic and muscular look. These differences are noticeable at first glance and play a key role in deciding which model will better suit your needs.

The biggest difference is in length and height. At 5063 mm, the Audi Q7 is a noticeable 77 mm longer than the Q8. This difference is mainly utilised in the rear of the car, allowing the Q7 to offer an optional third row of seats and a larger boot. At 1741 mm, it is also 36 mm taller, which gives the cabin a more airy feel and a better view. For large families or those who regularly carry bulky loads, the Q7 is clearly the more practical choice.

In contrast, the Audi Q8's proportions signal a sportier character. It is 25 mm wider than the Q7, which, combined with the lower body, creates an impression of stability and a hunkered-down stance. The lower, coupé-style roofline is the main design element that sets the Q8 apart. While this slightly limits headroom in the rear seats, it gives the car a more dynamic and aggressive look that will appeal to drivers who prefer style over maximum utility.

An interesting fact is that both models have the exact same wheelbase of 2995 mm. This means that the basic legroom for passengers in the front and second rows is very similar. The differences in overall length are therefore due to the longer body overhangs on the Q7.

Key Dimensions Comparison

Boot Space

Practicality and luggage space are key factors in large SUVs, and this is where the Audi Q7 and Q8 differ significantly. While the Audi Q7 is designed as a supremely practical family car, the Q8 sacrifices some utility for its sportier design with a sloping rear. This difference is immediately apparent when looking at the boot volume figures.

The second-generation Audi Q7 (4M, after the 2019 facelift) is the clear winner in this discipline. In its basic five-seat configuration, it offers a huge boot space of 865 litres. This is a volume that can easily accommodate the luggage of an entire family for a long holiday, sports equipment, or a large shopping trip. Folding down the rear seats creates an almost perfectly flat surface and increases the transport capacity to an impressive 2050 litres, making the Q7 a real workhorse.

The Audi Q8, despite sharing its technical underpinnings with the Q7, offers a noticeably smaller boot due to its elegant SUV-coupé silhouette. The basic volume is 605 litres, which is still a very generous figure that is perfectly adequate for most everyday situations. However, the 260-litre difference in favour of the Q7 is not insignificant. With the seats folded down, the Q8 provides a maximum volume of 1755 litres. Here too, it lags behind its more practical sibling, but it still offers more than enough space for transporting bulky items.

It is also important to mention the plug-in hybrid versions, where the luggage space is reduced due to the battery storage. In the Audi Q7 TFSI e (around 2020), the basic volume drops to a still solid 650 litres. The Audi Q8 TFSI e from the same period offers 505 litres. Even in the electrified variants, the Q7 maintains its lead in practicality.

Towing Capacity: A Battle of Heavyweights

The ability to tow a heavy trailer is a key parameter for many large SUV buyers. Whether you need to transport a boat, a caravan, or a horsebox, both the Audi Q7 and Q8 offer impressive figures, but with one crucial difference. While the Q7 is a more versatile powerhouse in this respect, the Q8 saves its maximum strength for a specific version.

The second-generation Audi Q7 (4M), especially after the 2019 facelift, is a real favourite for those who require maximum towing capacity. Most common engine options, such as the 45 TDI, 50 TDI, or 55 TFSI, can tow a braked trailer of up to 3500 kg with optional equipment (usually air suspension). Without this specification, the figure is around 2700 to 2800 kg. Remarkably, even the top-of-the-range 60 TFSI e plug-in hybrid retains the full 3500 kg capacity, making it an extremely versatile choice.

The Audi Q8, despite sharing the same technical platform, takes a slightly different approach to towing capacity. Most models from the relevant years, including the popular 45 TDI, 50 TDI, and 55 TFSI versions, have a standard maximum braked trailer weight of 2800 kg. This is still more than sufficient for most situations. However, if you're looking for the maximum, you have to turn to the only variant that matches the Q7 – the plug-in hybrid Q8 60 TFSI e, which can also tow 3500 kg.

For the buyer, this means a clear choice: if the absolute priority is the maximum towing capacity of 3.5 tonnes and you want to choose from more conventional engines, the Audi Q7 is a safer bet. If a solid 2.8 tonnes is enough for you, or you're looking for a plug-in hybrid with maximum power, the Q8 offers clearly defined and still very capable options.

Engine Duel: The Power of V6 and V8 Under the Bonnet

The Audi Q7 and Q8 share the same technical platform, which means their engine range is almost identical. For both models, the basis is formed by powerful three-litre six-cylinder engines, whether diesel (TDI) or petrol (TFSI), which are equipped with 48V mild-hybrid technology as standard to reduce consumption and provide a smoother ride. All engines are paired with an eight-speed Tiptronic automatic transmission and the legendary quattro all-wheel drive. The differences only appear in the top-of-the-range sports versions, where the Q8 offers an even more extreme variant than the Q7.

Audi Q7: Comfort and Power for Long Journeys

The Audi Q7's engine range is focused on confident and comfortable performance, ideal for family travel and long distances. The basis is the proven 45 TDI and 50 TDI diesel engines, which offer an excellent compromise between dynamics and fuel consumption. The petrol alternative is the 55 TFSI, which provides a more refined and quieter operation. For environmentally conscious drivers, plug-in hybrid versions 55 TFSI e and 60 TFSI e were also available. The pinnacle is the sporty SQ7 model, which was initially available with a massive eight-cylinder diesel and switched to an equally powerful petrol V8 from 2020.

Audi Q8: Sporty Elegance with Extreme Performance at the Top

The Audi Q8 shares its basic engine line-up with the Q7, including the popular six-cylinder 45 TDI, 50 TDI, and 55 TFSI, as well as the plug-in hybrid variants. Here too, at the top of the standard range is the sporty SQ8 model, which, like the SQ7, underwent a change from a diesel V8 to a petrol V8. However, the key difference and the ace up the Q8's sleeve is the existence of the top-of-the-line RS Q8 version. This model, which the Q7 does not offer, is powered by a brutal four-litre twin-turbocharged V8 and offers the dynamics of a supercar in an SUV-coupé body.

Verdict and Recommendation

For most drivers, the choice of engine will depend more on personal preference than on the differences between the models.

• For high-mileage drivers: The 45 TDI and especially the 50 TDI diesel engines are an ideal choice in both cars, thanks to their excellent torque and favourable fuel consumption on long journeys.
• For petrol lovers: The refined and powerful 55 TFSI engine provides more than enough dynamism in both models for daily driving and a brisker pace.
• For those looking for maximum performance: This is where the paths diverge. While the SQ7 is the ultimate family SUV with stunning performance, the Audi Q8 goes even further. If you crave the absolute pinnacle and uncompromising dynamics, the RS Q8 is the clear choice, which the Q7 cannot compete with.

Choosing the right engine is absolutely key to long-term satisfaction with the car. We have compiled the following recommendations based on a combination of performance, real-world fuel consumption, owner feedback, and mechanical reliability. With both models built on the same platform, you will encounter a similar range of engines, but the character of each car favours a different choice.

For the Audi Q7, we recommend: 50 TDI quattro (210 kW)

For a large family SUV, which the Audi Q7 undoubtedly is, the more powerful version of the three-litre V6 diesel is the ideal choice. It offers a perfect balance of confident power, touring comfort, and reasonable running costs. With 210 kW (286 hp) of power and a massive 600 Nm of torque, the engine always has enough power, whether you're fully loaded for a holiday or towing a heavy trailer.

• Why it's the best choice: This engine suits the character of the Q7 best. Its power is available at low revs, which means a quiet and calm ride on long journeys. In conjunction with the eight-speed Tiptronic automatic transmission and quattro drive, the ride is smooth and safe in all conditions. Real-world fuel consumption at a calm pace is between 8 and 9 litres per 100 km, which is an excellent figure for such a large and heavy car.
• Technical advantages: The engine is equipped with a 48V mild-hybrid system, which helps to cover turbo lag and allows for longer "coasting" with the engine off, thus saving fuel. The refinement of its operation is at the top of its class.
• Potential risks: As with many modern diesels, attention must be paid to the diesel particulate filter (DPF), which can clog up during frequent short city trips. It is also a good idea to check the functionality of the 48V mild-hybrid system, as its starter-generator could occasionally fail in early model years. Regular oil changes for both the engine and the gearbox are important.
• Who is it ideal for: For drivers who often travel long distances, for large families, and for those who need a reliable and strong partner for towing. It is a sensible choice that, however, does not lack emotion thanks to its commanding power.

For the Audi Q8, we recommend: 55 TFSI quattro (250 kW)

While the Q7 is primarily a practical family car, the Q8 with its SUV-coupé body targets style and dynamics. A refined and powerful petrol six-cylinder engine is better suited to this character. The 55 TFSI engine provides velvety smooth operation, instant throttle response, and a soundtrack that better matches the car's sporty-luxury focus.

• Why it's the best choice: The 250 kW (340 hp) of power and 500 Nm of torque give the Q8 a lightness and agility that is not present to the same extent in the diesel version. The acceleration is impressive, and the overall character of the engine is more premium. For drivers for whom fuel consumption is not an absolute priority, this unit offers a much richer driving experience.
• Technical advantages: The turbocharged three-litre V6 is exceptionally quiet and vibration-free during calm driving, but under throttle, it can produce a pleasant sporty tone. Here too, the 48V mild-hybrid system helps with smoothness and efficiency.
• Potential risks: The main disadvantage is, logically, higher fuel consumption. While you can get around 10 l/100 km outside the city, in city traffic or during dynamic driving, expect values between 12 and 15 litres. As with the TDI, it is a good idea to check the functionality of the mild-hybrid system. A consistent service history with regular oil changes is key.
• Who is it ideal for: For drivers who emphasise style, performance, and refinement. It is the choice for those who want to utilise the dynamic potential of the Q8's chassis and enjoy every kilometre behind the wheel, even at the cost of higher fuel expenses.

Real-world consumption: How do the Q7 and Q8 engines perform?

Official fuel consumption figures are one thing, real-world operation is another. Especially with large and heavy SUVs like the Audi Q7 and Q8, driving style and route profile play a crucial role. To get the most accurate picture, we looked at data from real owners who carefully record their refuelling on the German portal Spritmonitor.de. This data gives us a much more realistic idea of the running costs that can be expected from the most common engine versions.

The following table shows the average consumption for the key engine versions of the 4M generation, which is relevant for the used car market for vehicles approximately four years old.

As the data shows, the diesel six-cylinders are clearly the more economical choice. The difference between the weaker 45 TDI variant and the more powerful 50 TDI is negligible in practice, usually in the order of a few tenths of a litre. Most drivers will comfortably fit within the 8.5 to 9.5 l/100 km range with both versions, which is a very respectable figure for an over two-tonne SUV with all-wheel drive. For those who often drive long distances on the motorway, the TDI engines represent an ideal compromise between dynamics and running costs.

The 55 TFSI petrol six-cylinder offers smoother operation and higher performance but requires more frequent visits to the petrol station. Its real-world consumption is around 11.5 to 12 litres, but during dynamic driving or in city traffic, it's not a problem to exceed the 13 l/100 km mark. The slightly lower average consumption of the Q8 compared to the Q7 for both engine types can be attributed to slightly better aerodynamics and a marginally lower weight. In the real world, however, the differences are so small that the average user will hardly notice them.

Ultimately, fuel consumption should not be the deciding factor when choosing between the Q7 and Q8. With identical engines, the running costs are very similar. The choice will therefore depend more on personal preferences – whether you prefer the maximum practicality and the option of seven seats in the Q7, or the more stylish and sportier design of the five-seater Q8.

Used car price range: Premium comes at a price

When comparing the prices of used Audi Q7 and Audi Q8 models, a clear trend is noticeable – the sportier-styled Q8 holds a higher price than its more practical sibling, the Q7. This difference is due not only to the Q8's later market launch date but also to its positioning as a more stylish and exclusive alternative.

Audi Q7: Family luxury for more affordable money

The prices of used Audi Q7 models from 2020 to 2022 on the Czech market range widely, starting at approximately €47,000. For this price, you can get cars with higher mileage (often over 150,000 km) and the basic 45 TDI diesel engine.

Cars with the more sought-after 50 TDI (210 kW) engine, popular S line trim, and mileage under 100,000 km typically range from €53,000 to €65,000. The price further depends on specific equipment, such as air suspension, a panoramic roof, or advanced assistance systems. The plug-in hybrid versions or the more powerful SQ7 are priced even higher.

Audi Q8: Sporty elegance with a higher price tag

The Audi Q8, as an SUV-coupé, starts on the used car market at a higher price level. The cheapest units from 2020-2021 with higher mileage and the weaker 45 TDI engine rarely appear below the €57,000 mark.

Most of the offers are concentrated on the popular 50 TDI version in the S line trim. Here, prices for cars with reasonable mileage (up to 100,000 km) most often range between €66,000 and €82,000 and more. Similar to the Q7, optional equipment plays a key role here, which can increase the price by thousands of euros.

Key factors influencing the price:

• Engine options: More powerful and desirable engines (e.g., 50 TDI vs. 45 TDI) logically command a higher price.
• Equipment: The S line package is very popular, and cars equipped with it are more expensive. Other valued features include HD Matrix LED headlights, air suspension, night vision, or the premium Bang & Olufsen audio system.
• Mileage and history: The number of kilometres driven and a documented service history are clear factors. Cars with low mileage and regular servicing at an authorised centre are significantly more expensive.
• Vehicle condition: The overall technical and visual condition naturally has a major impact on the final price.

In conclusion, for a similar year of manufacture, mileage, and engine, the Audi Q8 will typically be €8,000 to €16,000 more expensive than the Audi Q7. The choice thus depends on the buyer's priorities – whether they prefer the practicality and seven seats of the Q7, or the dynamic design and exclusivity of the Q8.

Safety Comparison: Five Stars with Minor Differences

When choosing a premium SUV, safety is a key factor, and in this area, both Audi models perform equally well at first glance – both boast a five-star rating from Euro NCAP. However, it is important to look at the details and the context of the tests. Both the Audi Q7 and Audi Q8 were tested in 2019, which means their results are directly comparable under the then-current, already quite strict protocols. These tests included more demanding scenarios than in previous years, such as cyclist detection and emergency braking in various situations.

Audi Q7

The Audi Q7 underwent Euro NCAP crash tests in 2019 and received a full five stars. It achieved excellent results in individual categories: adult occupant protection was rated at 92% and child occupant protection at 86%. In the area of protecting vulnerable road users, such as pedestrians and cyclists, the Q7 scored 71%. Its arsenal of assistance systems, including autonomous emergency braking and lane keeping assist, was rated at 72%. These figures confirm that the Q7 remains a very safe family car even after its facelift.

Audi Q8

Just a few weeks later in the same year, the more stylish SUV-coupé Audi Q8 also underwent Euro NCAP tests. The result was practically identical, also earning five stars. In the details, however, the Q8 performed marginally better. Adult occupant protection was evaluated at 93% and child protection at 87%. The score for the protection of vulnerable road users was an identical 71%, and the assistance systems scored one percentage point higher, at 73%. Euro NCAP states in its report that the Q8 shares most of its structure with the Q7, which explains the very similar results.

Although the percentage differences are minimal and practically negligible in the real world, on paper, the Audi Q8 is a hair better in both occupant protection and the rating of its assistance systems. Nevertheless, both models represent the absolute pinnacle of safety in their class, providing comprehensive protection thanks to their robust construction and modern electronic aids. The decision between them in terms of safety will therefore be more about personal preference than objective differences.

In addition to the standard equipment, each model offers several unique features that may be decisive for the customer. While the Audi Q7 focuses on maximum comfort and practicality for a large family, the Q8 counters with a sportier style and technological refinements.

Audi Q7: Maximum comfort and family versatility

The Audi Q7 made a huge leap in technology after its 2020 facelift, bringing it closer to its sibling, the Q8. Nevertheless, it retains unique features focused on practicality and comfort.

• Digital cockpit and infotainment: Following the Q8's example, the Q7 also received the modern MMI touch response system with two touch screens (upper 10.1" and lower 8.6") with haptic and acoustic feedback. The Audi virtual cockpit, a 12.3-inch digital instrument cluster, also became standard.
• Chassis for every situation: The optional adaptive air suspension not only allows for changing the damper stiffness but also the vehicle's ride height. It offers five levels: from a dynamic lowering for sporty driving to "off-road" and "lift" modes for driving on rough terrain. A practical detail is the ability to lower the rear of the car with a button in the boot for easier loading of heavy items.
• Practicality first: A key advantage of the Q7 is the third row of seats, which elegantly folds and unfolds electrically using buttons. This makes it a full-fledged seven-seater SUV, ideal for large families. The second row of seats is also slidable and has an adjustable backrest for maximum versatility.
• Advanced technologies for the driver: To make maneuvering such a large vehicle easier, all-wheel steering is available, which turns the rear wheels by up to 5 degrees. At low speeds, they turn in the opposite direction to the front wheels, reducing the turning circle, while at higher speeds, they turn in the same direction for better stability.
• Top-of-the-line headlights: The optional HD Matrix LED headlights with laser high beam provide exceptional light output and can precisely "mask out" surrounding traffic to avoid dazzling other drivers. They also perform impressive light animations when locking and unlocking the car.

Audi Q8: Sporty elegance and technological avant-garde

The Audi Q8 was conceived from the start as a more stylish and dynamic alternative to the Q7. Its equipment and design elements clearly prove this.

• A design that catches the eye: The Q8 is distinguished by its frameless doors and a flowing coupe-style silhouette. A more aggressive look is supported by the S line and Black optic packages, which emphasize the car's sporty character.
• A pioneer in the interior: The Q8 was the first to introduce the MMI touch response concept, which became the benchmark for other Audi models. Two displays are elegantly integrated into the dashboard, surrounding the driver.
• Lighting technology of the future: In addition to HD Matrix LED headlights, the Q8 is the brand's first SUV to offer optional digital OLED rear lights. These not only allow the driver to choose from several light signatures but also include a safety feature – if another car approaches the stationary vehicle from behind to within less than two meters, all OLED segments light up as a warning.
• Agility and driving dynamics: Like the Q7, the Q8 can also be equipped with adaptive air suspension and all-wheel steering. However, the Q8's suspension is tuned to be stiffer and sportier as standard, which, combined with a lower center of gravity, results in better handling and less body roll in corners. The rear-wheel steering further enhances agility on tight switchbacks.
• Luxury features for occupants: Higher trim levels offer features that elevate comfort to the level of luxury sedans. These include, for example, massage and ventilated seats or the Air quality package, which includes an ionizer and a subtle interior fragrance.

Audi Q7

Advantages:

• Exceptional practicality and spaciousness: The standard three rows of seats can accommodate up to seven passengers, making the Q7 an ideal choice for large families.
• Huge luggage compartment: With the third row of seats folded down, the Q7 offers up to 770 liters, which is significantly more than the Q8 and is among the best in its class.
• Excellent ride comfort: Thanks to the standard air suspension (on higher trims) and excellent cabin soundproofing, the ride is exceptionally comfortable and quiet, even on longer journeys.
• Versatility and towing capacity: With quattro all-wheel drive and the ability to tow a trailer weighing up to 3,500 kg (with more powerful engines), it is a very capable and versatile SUV.
• Better fuel consumption: Compared to the Q8, which has a more powerful engine as standard, the Q7's base engines offer lower fuel consumption.
• More favorable purchase price on the used car market: As a more traditional and family-oriented model, a used Q7 is often more affordable than a more stylish Q8.

Disadvantages:

• More conservative design: The Q7's appearance is more subdued and less emotional compared to the dynamically shaped Q8.
• Less agile handling: The taller body and focus on comfort mean the Q7 is not as nimble or sporty in corners as the Q8.
• Potential for electronic failures: Especially in post-facelift models (from 2020) with dual touchscreens, some owners complain about occasional freezing or slow infotainment responses.
• Limited space in the third row: The two rearmost seats are more suitable for children or for adults on shorter trips.

Audi Q8

Advantages:

• Attractive and sporty design: The sloping coupe-style roofline, frameless windows, and more aggressive stance make the Q8 one of the most stylish SUVs on the market.
• More dynamic driving characteristics: A lower center of gravity and a sportier-tuned suspension provide a more agile and enjoyable driving experience, especially in corners.
• More powerful standard engines: The Q8 comes standard with a more powerful six-cylinder engine, providing better dynamics and acceleration compared to the base versions of the Q7.
• Premium and modern interior: Although it shares many elements with the Q7, the Q8's interior feels more exclusive and driver-focused thanks to sportier seats and the overall concept.
• Generous space for five passengers: Despite the sloping roof, there is plenty of head and legroom for three adults in the rear seats, which are also slidable and reclinable.

Disadvantages:

• Less practical: It offers only five seats and a smaller luggage compartment (605 liters), which limits its use for larger families or transporting bulky items.
• Higher purchase price: As a more stylish and sport-oriented model, the Q8 is more expensive on the used car market than a comparably aged and equipped Q7.
• Worse rear visibility: The sloping roofline and smaller rear window slightly restrict the driver's rearward view.
• Touch controls can be distracting: Operating most functions via the two touchscreens requires more attention than traditional physical buttons.

What to Watch Out For: The Most Common Problems and Recalls

Based on our own CarAudit inspections, breakdown statistics, and service bulletins, we have compiled an overview of the most common problems that used car buyers should be aware of. Although both models are built on the same platform, their reliability differs slightly in the details.

Audi Q7 (4M, from 2015)

The second-generation Q7 is considered dramatically more reliable than its predecessor. Nevertheless, it has not escaped a few typical ailments, although most of them are more of an annoying than a fatal nature.

• Electronics and infotainment: In cars from the first years of production (approx. 2015-2017), software bugs in the MMI system sometimes occurred. These manifested as a frozen screen, non-functional phone pairing, or random reboots. Most of these problems were solved by software updates at an authorized service center. Before buying, it is a good idea to check that the system is running smoothly.
• Chassis and Steering: The air suspension, although comfortable, poses a potential risk after several years. In cars with higher mileage (over 150,000 km), leaks in the air bellows or compressor failures can occur. The problem manifests as the car sagging to one side after being parked for a long time. There was also a recall for cars manufactured until February 2019 due to a possible loosening of the bolted connection on the steering shaft, which in extreme cases could lead to steering failure. A thorough technical inspection of the car should check these components.
• 3.0 TDI Engines: These units are generally very reliable. Watch out for the AdBlue system, where the level sensor or the feed pump can fail. In older units, an oil leak around the valve cover may also occur. Cars manufactured between 2010 and 2017 were also part of a recall due to the engine control unit software related to emissions.
• Transmission: The eight-speed Tiptronic automatic transmission is robust but requires regular oil changes (ideally every 60,000 km). Neglected maintenance can manifest as jerking during gear shifts.

Summary for the Q7: Most problems relate to the electronics and chassis in higher-mileage cars. The mechanical foundation is very solid. A careful physical inspection of the used car and a check of its service history are key.

Audi Q8 (4M8, from 2018)

The Audi Q8 shares its technology with the Q7, but as a newer model, it has already had some of its "teething problems" sorted out. Nevertheless, it has its own specific issues, often related to the mild-hybrid system.

• Mild-Hybrid System (MHEV): Cars from the first years of production (especially 2019-2020) experienced problems with the 48V system. The most common issue was a failure of the starter-generator (BAS), indicated by an illuminated warning light and a "drivetrain malfunction" message. The repair was initially expensive, but Audi later released improved parts and software updates that resolve the issue. When buying, it is crucial to verify that the car starts and the start-stop system works flawlessly.
• Electronics and Software: Similar to the Q7, the infotainment system can sometimes act up, typically with slower responses. Owners sometimes complain about false warnings from assistance systems, which is often caused simply by dirty sensors in the bumper or on the windshield.
• Chassis: There was a recall concerning incorrect rear axle alignment on cars from 2019-2021, which could lead to uneven tire wear. Furthermore, a recall was recorded for the risk of steering failure, similar to the Q7.
• Recalls: The Q8 model has been part of several recalls. In addition to the aforementioned steering and alignment issues, there were recalls for potential overheating of high-voltage battery cells in hybrid versions (model years 2019-2024) and insufficiently attached side airbags (model year 2023). It is therefore crucial to use the VIN code to verify that the vehicle has undergone all necessary service actions.

Summary for the Q8: The main risk here is the more complex 48V mild-hybrid system in the early model years. Compared to the Q7, there are fewer reports of problems with the air suspension, which is also due to the lower average age of the cars on the market. An independent inspection of the car's technical condition is an absolute must here as well.

When buying a used car, a thorough inspection is key, and premium models like Audi Q7 and Q8 are no exception. Here are a few specific points to focus on with these two SUVs.

When Choosing an Audi Q7 (Type 4M, from 2015)

• Air Suspension Behavior: During the test drive, try all the chassis setting modes (Comfort, Dynamic, Allroad, etc.). Observe whether the car changes its ride height quickly and smoothly and whether there are any hissing or creaking sounds coming from the wheel area. Repairing leaks or faulty compressors can be expensive.
• Functionality of the MMI System and Virtual Cockpit: Carefully examine the response of both infotainment system screens. Check for any freezing, restarting, or flickering. Try pairing your phone via Bluetooth and test all the main functions. Slow responses can mean outdated software, but also a hardware problem.
• Noise from the Axles During Maneuvering: In a parking lot or at low speed, turn the steering wheel fully to both extremes several times and start moving slowly. Any loud clicking, creaking, or popping can signal worn control arm bushings or a problem with the CV joints.
• Cold Starting the 3.0 TDI Engine: If possible, insist on starting the engine from completely cold. Pay attention to any rattling sounds in the first few seconds after starting, which may indicate wear on the timing chain and its tensioners, a financially demanding repair. The engine should start immediately and run smoothly.
• Checking the History and Service Records: For such a complex vehicle, a complete and verifiable service history is an absolute must. Regular oil changes for the engine are important, but so are changes for the Tiptronic automatic transmission (ideally every 60,000 km). A comprehensive vehicle inspection will give you certainty about its past.

When Choosing an Audi Q8 (Type 4M8, from 2018)

• Response of the MMI Touch Response Displays: The dual touchscreen system is standard. Verify that both displays respond correctly to touch and provide haptic (vibrational) feedback. Try entering an address into the navigation and controlling the air conditioning. Malfunctions can be caused by a software bug, but also by an expensive hardware failure.
• Mild-Hybrid System (MHEV): During the drive, monitor the function of the start-stop system and the car's "coasting" feature (driving with the engine off). Everything should be completely smooth and barely noticeable. Any jerking or error messages on the dashboard can indicate a problem with the 48V system or the starter-generator.
• Rear-axle steering: If the car is equipped with this feature, try maneuvering it in a tight space and taking a sharper corner at a higher speed. The system should noticeably reduce the turning radius and increase stability. Any creaking or jerky movements from the rear axle require an immediate check-up at a service center.
• Condition of the frameless windows: Open and close all the doors several times. Check if the glass panels seat properly into the seals and if the aerodynamic noise at higher highway speeds is within the normal range. A poorly adjusted window can cause water and noise to leak into the interior.
• Thorough inspection of the chassis and brakes: Given the high weight and performance of the Q8, the chassis and brake system are under extreme stress. A physical inspection of the car should focus on the condition of the brake discs and pads, oil leaks from the shock absorbers, and any play in the suspension arms.
