Audi Q3 vs. DS 7: Complete comparison 2026

The Audi Q3 is a popular premium compact SUV from Ingolstadt that wins over customers with its technological sophistication, precise craftsmanship, and unmistakable design. Standing against it is the French competitor DS 7, often known and sought after on the used car market under its original name DS 7 Crossback, which brings fresh avant-garde luxury, attention to detail, and extraordinary driving comfort to the segment. The following comparison will reveal whether rational German precision or charming French flair is the better choice in the luxury family car class, making your decision easier.

When you place the Audi Q3 and DS 7 side by side, you will immediately notice the different approach to size within the premium SUV segment. While the German representative sticks to the traditional proportions of the compact class, the French model deliberately balances on its upper limit and its dimensions peek into the segment above. This difference suggests at first glance that each of the cars will have a slightly different character on the road and offer different spatial possibilities.

In terms of specific numbers, the DS 7, with its length of 4,573 mm, is 73 to 89 mm longer than the Audi Q3 (depending on whether we are measuring the classic body or the slightly longer Sportback variant). We see a similar trend in width, where the DS 7, with a value of 1,895 mm, surpasses the Audi by a noticeable 46 to 52 mm. The difference in wheelbase is also fundamental, which is 2,738 mm long for the French car, which is 58 mm more than its competitor from Ingolstadt. These extra millimetres give the DS 7 a significantly more robust and representative appearance.

What does this mean for everyday life? Thanks to its larger external dimensions and longer wheelbase, the DS 7 naturally offers a more airy interior and more legroom for rear-seat passengers, which you will appreciate especially on longer family trips. On the other hand, the Audi Q3 can capitalise on its more compact build in the city. The smaller width and slightly shorter body make it easier to manoeuvre in narrow streets and park in tight underground garages, where the more expansive DS 7 can sometimes be a nuisance. In terms of external dimensions, the DS 7 plays the card of maximum space and majesty, while the Audi Q3 represents a more agile and nimble choice for urban traffic.

For families and active individuals, luggage space is often a deciding factor when choosing a premium compact SUV. Whether you are planning a regular weekend shop, transporting sports equipment, or a longer family holiday with several extra suitcases, every litre of volume and layout flexibility counts. Both compared SUVs, which are currently sought after on the used car market as roughly four-year-old vehicles, offer above-standard capacities in this regard, but with a slightly different approach to the overall use of interior space.

The Audi Q3 F3 generation (produced since 2018) offers a very solid basic volume of 530 litres in its standard SUV body version. Furthermore, the car features sliding rear seats, allowing the boot to be flexibly adapted to the current needs of the passengers. After fully folding the backrests, you get a maximum transport capacity of up to 1,525 litres. If you opt for the more stylish Audi Q3 Sportback variant with a sloping roof, the basic volume remains pleasantly preserved at 530 litres, but the maximum capacity after folding the rear row naturally drops to 1,400 litres due to the car's silhouette. It is also important to note that if you are looking for a plug-in hybrid version (TFSI e), you will have to accept a significant reduction in the boot – the stored batteries reduce the basic volume to a more modest 380 litres.

In contrast, the French DS 7 Crossback (1st generation, 2018–2022) confidently dominates in the discipline of practicality and makes full use of its slightly larger dimensions. In the basic configuration, it offers a generous volume of 555 litres, a space that comfortably accommodates packing for even bulkier family trips. A fundamental and very clever advantage of this French car is the fact that its plug-in hybrid versions (E-Tense) have exactly the same boot volume as models with a conventional internal combustion engine, thanks to the clever placement of the battery in the floor. After folding the rear seats, the capacity of the DS 7 increases to a respectable 1,752 litres and offers an almost flat loading surface, making it a great companion even for moving larger items.

When choosing a premium compact SUV, towing capacity plays an important role for many buyers – whether it's for installing a bike rack, transporting materials to a cottage, or towing a heavy family caravan. When comparing the Audi Q3 (F3 generation) and DS 7 Crossback, focusing on used cars roughly 4 years old (i.e., model years around 2021 to 2022), we encounter quite significant differences. The German car offers a generally more robust construction for heavier loads, while the French representative is more reserved in this regard.

The Audi Q3 is exceptionally well-prepared for towing trailers. Even the standard braked trailer weight starts at a respectable 1800 kg for common petrol engines (e.g., 35 TFSI). If you opt for more powerful diesel versions, such as the 40 TDI, the maximum towing capacity climbs to an excellent 2200 kg. In contrast, the DS 7 Crossback offers a braked weight of only between 1290 and 1315 kg for the base PureTech 130 petrol engine. The maximum possible value for this model is 1850 kg, which you can only get with the more powerful BlueHDi 180 diesel engine.

Particular attention should be paid to the increasingly popular plug-in hybrid versions, which significantly limit towing capacity due to the heavy traction battery. The Audi Q3 in the 45 TFSI e version has its towing capacity reduced to 1400 kg. For the DS 7 Crossback in the E-Tense 225 and 300 versions, this value drops even lower, to between 1200 and 1250 kg. In practice, this means that while a conventional Audi Q3 can easily tow a large caravan or even a car transporter trailer, the hybrid DS 7 is more suitable for a bit of extra luggage space in the form of a rear box or will suffice for a weekend trip to buy building materials with a small trailer.

Final Summary: If you plan to regularly tow heavy trailers or go on holiday with a large caravan, the Audi Q3 is clearly the more capable and versatile choice. On the other hand, the DS 7 is perfectly adequate for drivers who use a tow bar more for recreation, such as transporting e-bikes, or only occasionally for attaching a light unbraked trailer.

Powertrain and Drivetrain: Traditional Reliability vs. French Elegance

A comparison of powertrains between the Audi Q3 and DS 7 reveals two distinct approaches to premium compact SUVs, which is key to making the right choice in the market for roughly four-year-old used cars. While Audi plays it safe with a proven wide range of petrol (TFSI) and diesel (TDI) four-cylinder engines, emphasizing the sophisticated quattro all-wheel drive on more powerful versions, the French DS 7 Crossback focuses on a highly comfortable setup. For the French car, the primary roles are played not only by traditional diesel units for relaxed travel but especially by the advanced E-Tense plug-in hybrid (PHEV) systems with high performance and top-tier paper emission values. For buyers, this means that with Audi, they can easily find a classic diesel highway cruiser or a purist petrol with all-wheel drive. Conversely, the DS 7 will appeal to drivers who want to enter the world of electromobility through a hybrid powertrain or are looking for economical smaller diesel engines for everyday use.

Audi Q3 (F3 generation)

The core of the engine lineup for the Audi Q3 (current F3 generation) consists of the popular 1.5-liter 35 TFSI turbocharged petrol four-cylinder with cylinder deactivation technology, providing 110 kW. It commonly appears on the used car market with both a six-speed manual and a seven-speed S tronic dual-clutch automatic. For drivers preferring a more spirited ride and higher dynamics, there are the more powerful 2.0-liter 40 TFSI (140 kW) and the top-of-the-line 45 TFSI (180 kW), which were sold exclusively with quattro all-wheel drive. Diesel specifications built on the robust 2.0 TDI are highly sought after in the used car market. These can be found under the 35 TDI (110 kW) designation and the more powerful 40 TDI variant (147 kW, or 140 kW in earlier model years). The 40 TDI with all-wheel drive, in particular, is a phenomenal choice for long-distance travelers. For those interested in eco-friendly operation, Audi satisfied demand with the 45 TFSI e version, which is a plug-in hybrid combining a 1.4 TFSI four-cylinder and an electric motor with a total output of 180 kW.

DS 7 Crossback (1st generation)

The French DS 7 Crossback SUV (produced in its first generation since late 2017) covers a very wide power spectrum from 96 kW up to a thrilling 220 kW. The petrol entry level is represented by the 1.2 PureTech turbocharged three-cylinder with 96 kW, but for this heavier vehicle, the more powerful 1.6 PureTech four-cylinder units (in 133 kW and 165 kW versions) appeared more frequently on the market. Diesels play a crucial role for used car buyers here: the smaller 1.5 BlueHDi (96 kW) impresses with low fuel consumption, while the full-blooded 2.0 BlueHDi (130 kW) delivers effortless pull in every situation. As production data shows, more powerful conventional engines such as the PureTech 225 petrol or the BlueHDi 180 diesel were withdrawn from the range during 2020 and 2021. The manufacturer fully replaced them with innovative plug-in hybrids. E-Tense technology is the main asset of used DS 7s today. The lower-powered E-Tense 225 version drives the front axle, while the flagship E-Tense 300 adds a second electric motor at the rear – giving the car all-wheel drive, an enormous 520 Nm of torque, and a peak output of 220 kW.

Choosing the right engine is crucial for long-term satisfaction with a used car. The chosen unit determines not only daily dynamics and fuel consumption but, above all, future service costs and overall reliability. While Audi relies on continuously improved and proven Group technology for both petrol and diesel engines in the Q3, the DS 7 has undergone a more complex evolution on the market – from exceptionally durable large-displacement diesels to the more recent dominance of complex plug-in hybrids. Our recommendation for roughly four-year-old used cars thus takes into account real-world reliability, balanced performance, and ease of service without unnecessary risks.

For the Audi Q3, we recommend: 35 TFSI (110 kW / 150 hp)

This 1.5-liter turbocharged four-cylinder petrol engine represents the absolutely ideal and most rational choice for the vast majority of those interested in this premium SUV. Within the F3 generation, it is an exceptionally sophisticated and reliable unit that stands out in the range for its unrivaled ratio of purchase price, operating costs, and performance. Thanks to the Active Cylinder Technology (ACT), which shuts down two cylinders under low load, it can achieve real-world fuel consumption of around 6.5 liters per 100 km, while offering very quiet and refined operation. The engine is mechanically robust, does not suffer from oil dilution, and warms up quickly. It is an ideal companion for drivers looking for a versatile family car for daily short trips around town and the surrounding area, supplemented by weekend trips, where diesel engines (TDI) would face risks of diesel particulate filter (DPF) clogging.

What to watch out for:

• S tronic gearbox operation: Most used cars with this engine are paired with a seven-speed dual-clutch gearbox. During the test drive, focus on the smoothness of starts and behavior during slow crawling. If the car jerks unpleasantly, shudders, or has delays when pulling away, it usually indicates worn clutch plates or the need for mechatronics software adaptation. Early detection of this problem will save you from an expensive overhaul.
• Maintenance documentation: Always insist on a service history. The gearbox requires regular oil changes (ideally every 60,000 km), which is crucial for its long life and smooth shifting.

For the DS 7, we recommend: 2.0 BlueHDi 180 (133 kW / 180 hp)

Although this top-of-the-line diesel engine was phased out of production at the end of 2020 and replaced by plug-in hybrids, it can still be found on the market for four- to five-year-old used cars, and we strongly recommend seeking it out specifically. For the heavy and luxuriously tuned DS 7, the full-fat two-liter diesel is an absolutely perfect choice that outclasses the rest of the range. Its main technical advantage is the massive 400 Nm of torque, which guarantees effortless flexibility in every situation. The unit is standardly paired with the excellent and reliable eight-speed Aisin automatic (EAT8), which shifts silky smooth. Unlike newer complex hybrids (E-Tense), there is no risk of expensive battery degradation issues, and compared to the smaller and riskier 1.5 BlueHDi diesel, it possesses indestructible mechanics. In terms of purpose, it is a perfect highway cruiser for drivers covering long distances, rewarding them with real-world fuel consumption reliably under 6.5 liters.

What to watch out for:

• AdBlue injection system: The engine itself is considered a "workhorse," but its Achilles' heel is the emission system. During the inspection, carefully check the dashboard. Any warning about an emission system fault or the need for engine service is usually a symptom of urea (AdBlue) crystallization, which often damages the integrated pump in the plastic tank on the chassis. This is a very expensive repair.
• Problem prevention: The risk can be effectively minimized. We recommend adding a special anti-crystallization AdBlue additive to the tank immediately after purchase and subsequently with every urea refill. This inexpensive solution reliably extends the life of the entire system.

In the automotive world, it is an open secret that official fuel consumption figures provided by manufacturers often differ significantly from the reality of everyday driving. Although the modern WLTP measurement methodology has narrowed these gaps somewhat, for a true picture of fuel costs, it is always better to look at real-world data from drivers themselves. For this comparison of premium compact SUVs – considering models roughly four years old, i.e., the Audi Q3 generation F3 and the DS 7 Crossback 1st generation from 2018–2022 – we relied on aggregated user data from independent portals such as the German Spritmonitor.de. Here, it is clearly shown how much "on-paper" assumptions diverge from owners' experiences.

The interpretation of the data reveals several interesting trends. In both cases, diesel units (TDI for Audi and BlueHDi for DS) remain the most economical choice, with real-world consumption settling around a pleasant 6 liters per 100 kilometers. However, the data also reveals a typical weakness of small-displacement gasoline engines when powering relatively heavy and aerodynamically robust SUVs – the 1.2 PureTech three-cylinder gasoline engine in the DS 7 fails to save fuel in reality despite its smaller displacement and often hovers above 7.4 liters. With the more powerful 1.6 PureTech 180 version, expect consumption to safely exceed 8 l/100 km. Similarly, the plug-in hybrid versions of both models show a massive gap compared to laboratory promises; instead of the standardized 1.5 liters, their long-term real-world average without diligent daily charging is closer to just over 5 liters per hundred kilometers.

For a typical buyer of these used cars, clear recommendations follow. If you spend a lot of time on highways or regularly cover long distances, the 35 TDI and BlueHDi 130 diesel engines clearly make the most sense in terms of operating costs. Drivers who spend most of the week commuting in the city and its surroundings should consider plug-in hybrid alternatives. However, there is one crucial condition: you must have the ability to charge the vehicle regularly at home or at work. As soon as you stop recharging the battery, you are just carrying the dead weight of heavy batteries, and fuel consumption rises sharply. For more relaxed drivers looking for an uncomplicated gasoline compromise, the advanced 35 TFSI four-cylinder (1.5 TSI with cylinder deactivation) in the Audi appears to be a more balanced choice overall.

In conclusion, fuel consumption can play a fairly important role in the final choice between these two cars. While the used models of both brands are very close in cost for diesel and hybrid versions, the German Audi Q3 wins in terms of overall efficiency for classic gasoline engines. While the avant-garde DS 7 Crossback can charm the occupants with its extraordinary interior comfort and design, you will pay significantly more at the gas stations for choosing its purely gasoline engines.

Comparison of used car prices and depreciation

In the used car market, specifically when looking at models approximately four years old (2021–2022), the different approaches of both automakers and the perception of the brands by European customers are fully evident. While the Audi Q3 benefits from a strong German premium image and holds its value excellently, the French DS 7 (previously sold as DS 7 Crossback) on the other hand struggles with faster depreciation. However, this is exactly what makes it a hidden gem for used car buyers.

Price range in the used car market (2021–2022)

Here is an indicative overview of prices for approximately four-year-old vehicles with average mileage:

• Audi Q3 (2nd generation): Prices for well-maintained four-year-old units start at around €23,000 for the base 35 TFSI (1.5-liter) petrol engines with a manual gearbox or more modest equipment. Better-equipped S line versions with quattro all-wheel drive and more powerful engines commonly range between €31,000 to €37,000.
• DS 7 Crossback: For models of the same age, prices start at a very attractive €16,000 to €18,000, where in this range you can often find reliable 1.5 or 2.0 BlueHDi diesels paired with an automatic transmission. Even top-of-the-line E-Tense plug-in hybrid versions with 300 hp or models in the most luxurious trims like Rivoli or Opera can commonly be purchased in the range of €23,000 to €29,000.

Depreciation and price/performance ratio

The difference in depreciation (loss of value) is fundamental for these two luxury SUVs and clearly defines which used car is more suitable for which type of buyer.

Audi Q3 and investment stability:
Cars from Ingolstadt are known for their very stable residual value. Even after several years of operation, the Q3 model maintains a confident premium price tag. From the perspective of future resale, this is a huge advantage – the car does not lose value as quickly. For you as a current used car buyer, however, this means a higher initial investment and the need to accept that you will pay significantly extra for certain optional equipment features.

DS 7 as the used car king of equipment:
The DS brand faces slight caution from buyers in the European used car market, who often conservatively prefer established German models. The result is a disproportionately steeper price drop in the first years after production. For those interested in a used car, however, this is fantastic news. For an amount that often only covers the absolute basics for an Audi Q3, you get a top-spec DS 7 full of premium leather, massage seats, top-tier audio, and an advanced suspension with camera road scanning.

If protecting your investment before resale in a few years is key for you, the Audi Q3 represents a safe bet. However, if you are looking for maximum luxury, avant-garde design, and full equipment for a fraction of the original purchase price, a slightly used DS 7 is hard to beat on the market.

Both models, the Audi Q3 and the DS 7 (originally sold as the DS 7 Crossback), achieved the maximum five-star rating in independent Euro NCAP crash tests. However, when assessing safety in the used car market, it is necessary to view these results in the correct context and take into account the specific year of testing. Euro NCAP methodology is constantly evolving and becoming stricter. Percentage results from different years cannot always be directly compared, as newer tests place significantly more emphasis on the sophistication of active safety assistants, cyclist detection, or handling crisis scenarios at intersections.

The DS 7 model was evaluated in 2017, while the Audi Q3 underwent testing a year later, in 2018, when slightly stricter criteria were already in place. In these tests, Audi demonstrated exceptionally strong adult protection and benefited from standard modern assistants, including autonomous emergency braking (AEB) with pedestrian and cyclist response. In the case of the DS 7, passive occupant protection also received a high score. However, it is important to realize that Euro NCAP certifications have limited validity – for the French model, the validity officially expired in January 2024, as the 2017 standards no longer meet the latest, radically stricter requirements (a similar situation gradually applies to all cars tested in 2018).

This detailed data shows that the structural rigidity and passive safety of both cabins are at an excellent level. The main difference is found in the evaluation of safety assistance systems, where the Audi Q3 has a clear lead (85% compared to 76% for the DS 7). This result reflects the richer and more advanced integration of active safety in the standard equipment of the German SUV. Systems like Audi Pre Sense can reliably respond to impending collisions with pedestrians and other vehicles. Conversely, the DS 7 performs one percent better in child passenger protection, making it a very secure and attractive choice for families with small children even today.

In conclusion, both used SUVs offer a very safe environment for their occupants with a solid construction. However, thanks to the newer certification date and noticeably better results in the electronic assistants category, the Audi Q3 represents a slightly more modern and comprehensive safety package that better meets today's demands for active accident prevention.

In addition to standard equipment, each of the models offers something extra and brings a completely different approach to defining added value, practicality, and luxury for everyday use.

Audi Q3: Technological Precision and Maximum Versatility

• Smart Space Solutions: One of the Audi Q3's biggest trumps is its interior flexibility. The rear bench seat is already sliding by 150 mm as standard, allowing owners to easily choose between maximum legroom for rear passengers and a larger luggage compartment volume. A variable trunk floor is also a matter of course.
• Digital Ecosystem: The interior is dominated by the Audi virtual cockpit (a fully digital instrument cluster), which together with the MMI touch display forms an intuitive interface. Advanced navigation uses swarm intelligence from other Audi vehicles to more accurately predict traffic situations and find parking spaces.
• Advanced Lighting Technology: In higher trim levels, the Q3 offers Matrix LED headlights. Based on camera data, these can selectively turn off individual light-emitting diodes to "mask out" oncoming vehicles, allowing you to keep high beams on at all times without the risk of dazzling others.
• Sporting Genes and Engines: Customers looking for a more dynamic look appreciate the S line package, which modifies both the exterior and interior. However, a true specialty of the model range is the top-of-the-line RS Q3 version with the iconic 2.5-liter five-cylinder TFSI, an engine you won't find anywhere else in this category of compact SUVs.
• Highway Assistance Systems: Adaptive Cruise Assist cleverly combines the functions of adaptive cruise control, traffic jam assist, and lane-keeping assist. This provides significant relief for the driver during long highway journeys or stop-and-go city traffic.

DS 7: Parisian Avant-Garde and Uncompromising Comfort

• Predictive Suspension: A technological unique in its class is the DS Active Scan Suspension system. A camera located behind the windshield constantly scans the road ahead, detecting potholes or unevenness and adjusting the damping stiffness independently for each wheel in real-time. The result is a smooth, exceptionally comfortable ride.
• Iconic Design Details: The interior of the DS 7 resembles a luxury boutique. Among the most striking elements is the B.R.M R180 rotating analog clock on the dashboard, which appears upon starting the engine. Also unique is the guilloché finishing of the controls (Clous de Paris pattern) and the premium pearl stitching of the leather upholstery.
• Night Vision Technology: The DS Night Vision function uses an infrared camera integrated into the radiator grille. The system can warn the driver on the digital instrument cluster in time about pedestrians or animals at a distance of up to 100 meters, significantly increasing safety on unlit country roads.
• Electrified E-Tense Powertrains: While conventional engines take center stage for other brands, the DS 7 excels with powerful plug-in hybrid versions under the E-Tense label. These combine locally emission-free operation with high system output (up to 300 hp) and, in more powerful variants, offer all-wheel drive thanks to an independent electric motor on the rear axle.
• Light Dance: The model appeals even before the drive begins. The crystalline modules of the front LED headlights (DS Active LED Vision) light up in purple when the car is unlocked and spectacularly rotate 180 degrees. In addition to the impressive welcome ceremony, they provide excellent wide-angle visibility. Thicker laminated window glass then contributes to acoustic comfort.

The Audi Q3 is an ideal choice for those looking for a premium, well-crafted, and technologically advanced compact SUV with a slightly sporty spirit. It excels in value retention and offers a wide range of engines, appealing to buyers who prefer security, prestige, and the traditional quality of the German brand.

The DS 7 will primarily appeal to individualists who prioritize maximum comfort, a luxurious interior, and original design over sporty driving characteristics. As a used car, it represents a very smart choice, offering French charm and a level of equipment for a favorable price that would cost significantly more with the competition.

Based on our own CarAudit inspections, breakdown statistics, and long-term user experience, we have compiled an overview of the most common problems that buyers of roughly four-year-old used cars should watch out for.

Audi Q3 (F3)

The second-generation Audi Q3 is generally considered an above-average reliable premium SUV; however, with increasing mileage, specific faults may appear, especially in the area of electronics and dual-clutch transmissions.

• Electronics and infotainment: A common problem (especially in models from 2020–2022) is freezing, slow response, or spontaneous restarting of the MMI system and virtual cockpit. Most of these issues can fortunately be resolved within service via software updates; in rare cases, a more expensive replacement of the control module is necessary.
• Engines: With the popular 1.5 TFSI petrol engines, jerky running (the so-called "kangaroo effect") occasionally occurs during cold starts in freezing temperatures, which is usually solved by new control unit software. With the more powerful 2.0 TFSI versions, increased oil consumption and carbon buildup on intake valves may appear at higher mileages. For 2.0 TDI diesel engines, watch out for a clogged diesel particulate filter (DPF) if the car was driven mainly on short city routes.
• Transmission: The dual-clutch seven-speed S tronic automatic transmission can jerk or hesitate to shift when crawling at low speeds. Regular oil changes at least every 60,000 km are absolutely crucial for it. Neglecting this often leads to fatal and very expensive mechatronics failure.
• Chassis and brakes: Owners very often report premature wear of brake pads and discs, which is the price for the car's higher curb weight (especially in versions with quattro all-wheel drive). At mileages over 60,000 km, shocks may be heard from the front axle when driving over bumps; therefore, a thorough physical inspection of the used car is strongly recommended before the final purchase decision.

DS 7

The French avant-garde DS 7 model (formerly sold as DS 7 Crossback) offers top-tier travel comfort, but its more complex electronics and some used diesel engines require maximum caution before buying.

• Engines (Diesels): In the popular 1.5 BlueHDi diesel engine, the biggest threat is the narrow 7mm timing chain connecting the camshafts. In models produced until early 2023, there is a risk of it stretching or snapping, leading to engine destruction (later the manufacturer switched to a reinforced 8mm chain). A known and relatively expensive problem with both diesels (1.5 and 2.0 BlueHDi) is failing pumps and injectors in the AdBlue system tanks.
• Engines (Petrol and PHEV): Pure petrol 1.6 PureTech four-cylinders can suffer from carbon deposit formation on valves when used frequently in the city. In more modern E-Tense plug-in hybrid versions, onboard charger failures occasionally occur, and 2019 models had to undergo recalls due to traction and battery software issues.
• Electronics: Similar to its German competitor, the DS 7 also often struggles with a slow and freezing central display. More common here, however, are false warnings from blind-spot sensors, a malfunctioning rear parking camera, or problems with keyless entry.
• Chassis: The exclusive DS Active Scan Suspension system, which uses a camera to read the road and adjust damper stiffness, is extremely comfortable but prone to sensor failures. If the camera loses calibration or sensors fail, the suspension becomes unpleasantly stiff. A high-quality comprehensive car inspection is thus an absolute necessity for a used DS 7 to verify these systems.

When buying a used car, a thorough inspection is crucial, and for these two sophisticated models, there are specific points to focus on in detail before purchasing. To ensure that any hidden defects do not escape your attention, an independent physical car inspection is always recommended before buying.

When choosing an Audi Q3:

• S tronic (DSG) transmission: With the seven-speed dual-clutch automatic transmission, focus on smoothness during the test drive. Pay attention to slow crawling, hill starts, and switching between D and R modes. If the transmission jerks, hesitates, or makes metallic sounds, it could indicate an expensive clutch replacement or an impending issue with the mechatronics. Also, check the service book to see if the oil has been changed regularly (typically every 60,000 km).
• Smoothness of cold starts (35 TFSI engine): The popular 1.5 TSI petrol engine in earlier years of this generation (around 2019-2020) sometimes suffered from jerking and hesitation after a cold start. During the test drive, insist on starting the car completely cold and driving off smoothly immediately. If the car "hops," an official software update for the control unit is usually the solution.
• Software and MMI infotainment: The Audi MMI system in models around four years old can suffer from slow responses, occasional parking camera failures, or phone mirroring issues. Before driving, try pairing your phone via Apple CarPlay or Android Auto and quickly click through various menus to see if the screen freezes.
• Chassis condition and bushings: The Audi Q3 is a relatively heavy car for its size, especially in the quattro all-wheel-drive version or the plug-in hybrid (45 TFSI e). Find a road with a poor surface and listen carefully for any quiet, dull thumping from the front axle. This would indicate prematurely worn control arm bushings or stabilizer links.

When choosing a DS 7:

• Battery condition in the E-Tense version: The DS 7 model is very common on the used car market with a plug-in hybrid powertrain. In a four-year-old car, the high-voltage battery may already show slight degradation. Check the current estimated electric-only range in the on-board computer menu and ensure the seller provides all functional charging cables with the car.
• Active Scan adaptive suspension: This technology uses a camera behind the windshield to anticipate bumps and immediately adjusts the stiffness of the shock absorbers. During the test drive, try to safely drive over different types of potholes – the damping should be exemplarily comfortable and quiet. If the ride is unexpectedly stiff and harsh, the system may be reporting a fault, which represents a costly service intervention. For an accurate diagnosis of this system, a comprehensive car inspection is worthwhile.
• Electronics and interior features: The DS 7 impresses with a beautifully crafted but electronically demanding interior. Test every button on the center console, check if the B.R.M. rotating clock on the dashboard works smoothly, and focus on the reactions of the central touchscreen, which controls the air conditioning among other things. System lag is relatively common and often points to the need for a software update.
• Operation of PureTech petrol engines: If you are considering the purely petrol 1.6 PureTech variant, listen carefully during a cold start for any rattling sound from the engine. These units use a timing chain, which can stretch in more heavily used examples. The engine should have a smooth idle; otherwise, it could be due to valves clogged with carbon, which these engines are prone to during frequent short trips.
