Mazda 3 vs. Peugeot 308: Complete comparison 2026

The Mazda 3, also known in some markets as the Mazda Axela, has long attracted drivers with its sporty design and excellent driving characteristics that promise fun behind the wheel. It is up against the Peugeot 308, a typical representative of the French school of car design, which relies on an avant-garde style, a comfortable chassis, and an innovative interior with the i-Cockpit concept. Let's take a closer look at how these two different approaches to a compact car fare in a direct comparison and which one might be the right choice for you.

At first glance of the Mazda 3 and Peugeot 308, it is clear that although both cars fall into the same category of compact hatchbacks, their creators have chosen different philosophies regarding exterior dimensions. In its latest generation (BP, from 2019), the Mazda 3 is significantly longer and has a longer wheelbase, giving it a more elegant and sporty silhouette. In contrast, the Peugeot 308 (3rd generation, from 2021) counters with a greater width and a shorter body, promising better manoeuvrability in the city and a more spacious interior at shoulder level.

The Mazda 3 hatchback surpasses its French rival by a noticeable 93 mm in length. This difference, along with a 50 mm longer wheelbase, translates not only into elegant proportions but, above all, into potentially better ride comfort on longer journeys and more generous legroom for rear passengers. The Peugeot, on the other hand, is 57 mm wider, which the front-row occupants will appreciate, and its shorter profile makes parking in narrow streets easier. In terms of height, the cars are almost identical, with a difference of only a few millimetres.

The differences become even more pronounced with other body variants. The Mazda 3 offers an elegant Fastback (sedan) version, which, with a length of 4660 mm, is one of the longest cars in its class and targets more conservative customers. The Peugeot 308, on the other hand, scores points with families with its practical estate (SW) variant, which not only offers a huge luggage compartment but, with a length of 4636 mm and a wheelbase of 2732 mm, also provides maximum comfort for the crew. The choice thus depends not only on brand preference but also on whether you prefer the sporty elegance of a sedan or the uncompromising practicality of an estate.

Comparison of Key Dimensions

The size of the luggage compartment is one of the key factors that can decide a car purchase, especially for families or those who frequently transport larger loads. In this respect, the philosophies of the Mazda 3 and the Peugeot 308 differ significantly. While Peugeot places great emphasis on maximum usability and offers some of the best values in its class, Mazda prioritises elegant design, which results in a slightly smaller, though still very usable, boot.

In the hatchback body style, the Peugeot 308 has a clear advantage. Its basic volume of 412 litres comfortably surpasses the 351 litres offered by the Mazda 3. This difference of almost 60 litres means space for one small suitcase or several extra shopping bags in practice. With the rear seats folded down, the gap widens even more: the Peugeot provides up to 1323 litres, while the Mazda offers 1026 litres. It should be noted, however, that the plug-in hybrid and electric versions of the Peugeot 308 have a boot reduced to a still-respectable 361 litres due to the batteries.

If we compare the more practical variants, the differences are even more profound. The Mazda 3 is also available as an elegant sedan with a 450-litre boot, which is a solid value but lacks the versatility of a fifth door. It is up against the Peugeot 308 in the estate (SW) version, which is a true master of transport. With a basic volume of 608 litres, it outclasses not only the Mazda but also most of the competition. Folding the seats down creates a space with a staggering volume of 1634 litres. For families and active individuals for whom maximum space is a priority, the choice is clear.

Comparison of Luggage Compartment Volume

The ability to tow a trailer is a key factor for many drivers when choosing a car, whether for transporting materials or for weekend trips with a caravan. In this respect, the philosophies of Mazda and Peugeot differ significantly. The Mazda 3 opts for simplicity and consistency, while the Peugeot 308 offers a wider range of options depending on the engine.

The Mazda 3 fourth generation (BP, from 2019) provides a uniform maximum braked trailer weight of 1300 kg for most of its engine options, including the mild-hybrid petrol variants Skyactiv-G and Skyactiv-X. This is a solid value that is easily sufficient for a small caravan or a hobby trailer. Owners therefore do not have to limit their choice of engine too much if they plan on occasional towing.

On the other hand, the Peugeot 308 of the second (T9, until 2021) and third generation (P5, from 2021) shows its practical strength primarily in its diesel and hybrid versions. While the basic 1.2 PureTech petrol engines offer a comparable capacity of between 1200 and 1300 kg, the real difference comes with the BlueHDi engines. The second-generation 1.5-litre diesel can tow up to 1500 kg, and in the latest generation, even up to 1600 kg. This is a value that allows you to tow even a larger caravan. The third-generation plug-in hybrid versions also perform very well, with a capacity of up to 1500 kg.

For those who need maximum towing capacity, the clear winner is the Peugeot 308 with a diesel engine. However, if your requirements are more modest and you prefer a straightforward offering, the Mazda 3, with its uniform and sufficient value, is a reliable choice.

Engine Comparison: Japanese Naturally Aspirated vs. European Turbo

When it comes to engine selection, the Mazda 3 and Peugeot 308 take completely different paths, which is one of the most important differences for buyers. Mazda sticks to its Skyactiv philosophy, primarily relying on larger-displacement, naturally aspirated petrol engines supplemented with mild-hybrid technology. The goal is linear power delivery, immediate throttle response, and driving pleasure. In contrast, Peugeot is a master of downsizing – its lineup is built on award-winning turbocharged 1.2 PureTech three-cylinder engines, efficient BlueHDi diesels, and, in the latest generation, modern plug-in hybrids. Each approach has its merits and will appeal to a different type of driver.

Mazda 3: A Bet on Displacement and Unique Technology

The fourth-generation Mazda 3 (designated BP, from 2019) is found on the used car market almost exclusively with petrol engines, which are always paired with a 24V mild-hybrid system. The foundation is the two-litre four-cylinder e-Skyactiv-G with outputs of 90 kW (122 hp) or 110 kW (150 hp). It offers smooth and refined operation, but for more dynamic driving, it requires downshifting and keeping the revs high, which is typical for naturally aspirated units. For more demanding drivers, there is the unique e-Skyactiv-X engine, which combines the advantages of petrol and diesel engines thanks to SPCCI (Spark Controlled Compression Ignition) technology. It delivers up to 137 kW (186 hp), better low-end flexibility, and favourable fuel consumption. From 2019 to 2021, a 1.8 Skyactiv-D diesel unit (85 kW) was also briefly available, which is now only available on the used car market and represents a quiet and economical choice for high-mileage drivers.

Note: The 1.8 Skyactiv-D engine was only available until 2021.

Peugeot 308: The King of Downsizing and Electrification

The Peugeot 308 offers a much more diverse range of engines. On the used market, you will encounter both the facelifted second generation (until 2021) and the new third generation (from 2021). The backbone of the lineup is the turbocharged 1.2 PureTech three-cylinder engine with 81 kW (110 hp) or 96 kW (130 hp), which is lively and economical, but its reliability in older models requires attention. For long-distance journeys, the 1.5 BlueHDi four-cylinder diesel (96 kW) is ideal, characterized by low fuel consumption and refinement. A more powerful 2.0 BlueHDi diesel (up to 130 kW) was also available in the second generation, which today represents a powerful and economical option. The third generation brings a major difference, also offering plug-in hybrid versions with a combined output of 132 kW (180 hp) or 165 kW (225 hp), allowing for a purely electric range of around 60 km.

Note: The 2.0 BlueHDi engine was only available for the second generation (until 2020). Plug-in hybrid versions are only available for the third generation (from 2021).

Engine Verdict

• For drivers who prefer classic engineering and reliability: The Mazda 3 is the clear choice. Its naturally aspirated e-Skyactiv-G and innovative e-Skyactiv-X engines offer excellent response, refinement, and are considered very reliable.
• For those interested in low fuel consumption and frequent motorway travel: The Peugeot 308 with the 1.5 BlueHDi or the older 2.0 BlueHDi engines will be a more economical companion. The Mazda 1.8 Skyactiv-D diesel is also great, but its availability is limited.
• For modern and eco-conscious drivers: The third-generation Peugeot 308 with a plug-in hybrid powertrain is a more technologically advanced choice, allowing for zero-emission city driving. Mazda does not offer a competitor in this segment.
• For relaxed city driving: The base petrol engines of both models, the 1.2 PureTech and the 2.0 e-Skyactiv-G, do a good job. The Peugeot 308's engine feels livelier at low revs thanks to the turbo, while the Mazda 3 scores points for its smoothness.

Choosing the right engine is key to long-term satisfaction with a car. Our recommendations are based on a combination of performance, real-world fuel consumption, owner feedback, and mechanical reliability. Mazda and Peugeot take completely different approaches. While Mazda relies on larger-displacement, naturally aspirated petrol engines, which are a rarity today, Peugeot sticks to a strategy of small-displacement turbocharged units, both petrol and diesel.

For the Mazda 3, we recommend: 2.0 e-Skyactiv-G (90 kW/122 hp or 110 kW/150 hp)

This engine is unique these days. It's a two-litre, naturally aspirated four-cylinder that does without a turbocharger. For a used car buyer, this is great news as it represents a safe bet and long-term reliability. The engine has a very refined and linear character – power builds smoothly with revs, which will be appreciated by drivers who enjoy the driving experience. The mild-hybrid system (24V) helps reduce fuel consumption in the city and during acceleration; in real-world driving, you can achieve 6 to 6.5 l/100 km. Both power versions (122 and 150 hp) are almost identical in terms of hardware and provide sufficient dynamics for everyday driving.

• Why is it the best choice? It combines exemplary reliability, low service costs, and a pleasant driving experience. The absence of a turbo means fewer potential problems in the future.
• Technical advantages: Smooth power delivery from low revs, great throttle response, and a precise manual gearbox that is a joy to shift.
• Known risks: This engine is considered one of the most reliable in its class. At higher mileages, carbon deposits typical of direct-injection engines may theoretically appear, but regular use of quality fuel and occasional spirited driving minimize this risk.
• Who is it ideal for? For drivers who cover an average number of kilometres annually in varied traffic and value reliability and a classic engine character more than aggressive turbo punch.

For the Peugeot 308, we recommend: 1.5 BlueHDi (96 kW/130 hp)

Although the 1.2 PureTech petrol engine is very common, we recommend caution with used cars due to its oil-immersed timing belt, which can cause fatal engine damage if maintenance is neglected. That's why our choice for the Peugeot 308 is the 1.5 BlueHDi diesel unit. This engine is a great example of a modern diesel: it's quiet, refined, and incredibly economical. Thanks to its high torque of 300 Nm, it offers confident flexibility for overtaking and on the motorway. Combined with the eight-speed EAT8 automatic transmission, it forms a perfectly matched pair for comfortable and economical travel. Long-term fuel consumption easily stays below 5 l/100 km.

• Why is it the best choice? It offers a fantastic balance between performance and fuel consumption. Compared to its petrol counterpart, it is perceived as a more mechanically durable choice for the long term.
• Technical advantages: Strong mid-range pull, excellent sound insulation, and low real-world fuel consumption. It pairs perfectly with the EAT8 automatic transmission.
• Known risks: Like every modern diesel, this one is equipped with an AdBlue (SCR) system. Problems with sensors in the urea tank or the injector can occasionally occur, which can lead to more expensive repairs. When buying, it is crucial to verify that the system is not showing any error messages. Frequent short city trips pose a risk of clogging the diesel particulate filter (DPF).
• Who is it ideal for? For drivers who cover a high number of kilometres annually (over 20,000 km), frequently drive on motorways, or simply want to minimize fuel costs.

The Battle for Every Drop: Real-World Consumption of the Mazda 3 and Peugeot 308

The official consumption figures provided by manufacturers are one thing, but real-world driving is another. Laboratory cycles often don't reflect everyday challenges like city traffic jams, hilly terrain, or a more dynamic driving style. That's why we looked at data from drivers themselves, for example, from the German portal Spritmonitor.de, to find out how the two rivals perform in the real world. We are primarily comparing the generations relevant to the used car market – the Mazda 3 BP generation (from 2019) and the Peugeot 308 second generation post-facelift (2017–2021) and the succeeding third generation (from 2021).

The following table shows the average real-world consumption of the most common engine versions, as reported by the owners themselves.

Different Philosophies, Similar Results

At first glance, it's clear that both manufacturers take a different approach to efficiency. Mazda relies on larger-displacement naturally aspirated engines (so-called "rightsizing") and mild-hybrid technology, while Peugeot uses small-displacement turbocharged three-cylinder PureTech engines. In the real world, however, the differences in petrol engines blur. The naturally aspirated two-litre in the Mazda 3 averages 6.6 l/100 km, which is only slightly less than the turbocharged 1.2-litre in the Peugeot 308 with an average of 6.7 l/100 km. Interestingly, Mazda manages to keep its real-world consumption very close to the official figures, whereas with small-displacement turbo engines like the PureTech, the spread between calm and dynamic driving tends to be significantly larger.

For drivers who cover long distances, especially on motorways, the clear winner is the diesel Peugeot 308. The 1.5 BlueHDi engine, with an average consumption of around 5.1 l/100 km, is a very economical choice that Mazda does not offer a direct competitor for in its latest generation (the Skyactiv-D engine was only on the market for a short time).

As a result, fuel consumption is not a deciding factor between these two cars when considering the petrol variants. The Mazda 3 offers the more refined performance of a naturally aspirated four-cylinder engine with very favourable and stable fuel economy. The Peugeot 308 counters with the flexibility of its turbocharged engine and has an ace up its sleeve for long-distance drivers in the form of an exceptionally economical diesel. The choice, therefore, depends more on the preferred engine character and the type of journeys most frequently taken.

Used Car Price Comparison: Mazda 3 vs. Peugeot 308

A look at the used car market reveals significant price differences between the Mazda 3 and the Peugeot 308. The Japanese precision and more premium feel of the Mazda are reflected in a higher residual value, while the Peugeot offers a more attractive initial investment.

Mazda 3 (4th generation, from 2019)

The fourth generation of the Mazda 3, known as the BP, holds its value relatively well even as a used car. This is due to its attractive design, high-quality interior, and the reputation of its reliable naturally aspirated Skyactiv-G engines.

• Price range: The oldest cars from 2019 range from €16,000 to approximately €21,000. The average price for a 2019 model is often around €17,000.
• What affects the price: The price is most influenced by the equipment and engine. Cars with the unique Skyactiv-X engine or in higher trim levels (e.g., Selection, Luxury) and with an automatic transmission can exceed €21,000. Lower mileage and a complete service history are, of course, key factors in maintaining a high value.

Peugeot 308 (2nd generation, post-facelift, 2017–2021)

As a direct competitor to the 2019 Mazda 3, we have the second-generation Peugeot 308 (T9) after its update. This model is significantly more affordable on the used market and offers excellent value for money.

• Price range: Prices for facelifted models from 2018-2020 start significantly lower. The cheapest second-generation units can be purchased for under €8,000, but these are older cars with higher mileage. Well-maintained models from 2018 sell on average for prices between €9,000 and €10,000.
• What affects the price: For the Peugeot, the engine is a major factor, with the economical BlueHDi diesel engines being highly sought after. The more practical estate (SW) body style and higher trim levels like Allure or GT Line also increase the price. However, despite its rich equipment, the 308 is noticeably cheaper than the Mazda 3 when comparing similar years and mileage.

Verdict

The choice between these two models is clearly defined from a price perspective. The Peugeot 308 represents a rational and more affordable option, offering a modern car with good equipment and low running costs for less money. In contrast, the Mazda 3 is the choice for drivers willing to pay extra for a more premium feel, exceptional design, and acclaimed reliability, which is reflected in its higher residual value.

Safety: A Battle of Generations and Testing Protocols

When comparing safety, it is crucial to realise that both cars underwent Euro NCAP crash tests in different years and according to different, stricter criteria. Although the star rating provides a quick overview, the detailed percentage results and the context of the testing reveal significant differences in the approach to protecting occupants and other road users.

Mazda 3 (tested 2019)

The fourth-generation Mazda 3 was tested by Euro NCAP in 2019 and received a full five-star rating. It particularly excelled in the adult occupant protection category, achieving an outstanding score of 98%. This result was one of the best of that year and attests to the exceptionally strong and well-thought-out design of the Skyactiv-Vehicle Architecture body. It also performed excellently in child occupant protection (87%) and vulnerable road user protection (81%), where it scored maximum points for the protection of pedestrians' legs and pelvis. The 73% rating for safety assist systems was in line with the standards of the time when the car was launched.

Peugeot 308 (tested 2022)

The third-generation Peugeot 308 was tested in 2022, under significantly stricter rules. It received four stars, which should not automatically be interpreted as a worse result. The newer methodology places much greater emphasis on advanced assistance systems and protection in more complex crash scenarios. The ratings of 76% for adult occupant protection and 84% for child protection are still solid figures. However, the tests revealed some weaknesses, such as only marginal protection for the driver's chest in a frontal impact and the absence of a centre airbag to prevent contact between front passengers. The lower scores for vulnerable road user protection (68%) and safety assist systems (65%) primarily reflect the more demanding requirements of the new tests, which include scenarios such as turning across the path of a cyclist.

Conclusion: Which Car is Safer?

Although the Mazda 3 has five stars and better percentage results on paper, its test was conducted according to older, less stringent rules. The Peugeot 308 was tested three years later using a stricter methodology. Its four stars may, paradoxically, signify a comparable, and in some respects more modern, level of safety, especially concerning responses to new traffic situations. The Mazda excels in passive safety and body rigidity. The Peugeot, despite a weaker result in adult protection, had to meet more demanding criteria for its assistance systems. The choice, therefore, depends on your priorities – whether you prefer the near-perfect passive protection of the Mazda 3, or the more modern, albeit not perfectly executed, safety package of the Peugeot 308, tested to the latest and strictest standards.

In addition to standard equipment, each model offers several unique features that can be decisive for the customer. While Mazda focuses on premium craftsmanship and innovative technology, Peugeot counters with an avant-garde interior concept and practicality.

Mazda 3: Premium Feel and Unique Technology

The fourth-generation Mazda 3 (from 2019) targets drivers who appreciate quality craftsmanship, advanced technologies, and, above all, the joy of driving. Its interesting features focus on connecting the driver with the car.

• Revolutionary Skyactiv-X engine: This is a world-first – a petrol engine that uses compression ignition similar to a diesel. The result is a combination of the low fuel consumption and flexibility of a diesel engine with the responsiveness and refinement of a petrol unit. It is often paired with a mild-hybrid system.
• Minimalist interior and controls: The cabin gives the impression of a car from a class above. It is dominated by high-quality materials and a driver-focused design. The 8.8-inch infotainment screen is intentionally not a touchscreen; it is controlled exclusively via an intuitive rotary knob on the center console. Mazda considers this solution safer as it does not distract the driver.
• Standard head-up display: A major competitive advantage is the standard projection head-up display. All important information, such as speed, navigation instructions, or assistant warnings, is projected directly onto the windshield into the driver's field of vision.
• Availability of all-wheel drive (AWD): In the compact hatchback segment, 4x4 drive is rather an exception. However, the Mazda 3 offers it with more powerful engines, which increases confidence and traction on wet or snowy roads.
• Premium Bose audio system: Higher trim levels are often equipped with a top-of-the-line Bose audio system with 12 speakers, providing exceptionally clear and spatial sound.

Peugeot 308: Avant-Garde i-Cockpit® and Practicality

The second-generation Peugeot 308 after its facelift (2017–2021) stands out primarily for its futuristic and bold interior concept, complemented by unexpected practicality and efficient engines.

• Distinctive i-Cockpit®: The most prominent feature is the driver's station layout. It consists of a small, sportily shaped steering wheel, above which is a raised instrument cluster. The driver looks at the gauges over the steering wheel, not through it. This solution takes a moment to get used to, but many come to love it for the feeling of control and quick overview.
• The car's touch-sensitive center: The dashboard is dominated by a large touchscreen that integrates the controls for most of the car's functions – from media and navigation to air conditioning. This results in a minimum of physical buttons in the interior and a very clean design.
• Master of interior space: Although the Peugeot 308 is one of the most compact cars in its class in terms of exterior dimensions, its luggage compartment is one of the largest. This makes it an ideal companion for families and active individuals.
• Award-winning PureTech engines: Under the bonnet, you will often find the award-winning 1.2 PureTech three-cylinder petrol engines with a turbocharger. They are known for their liveliness, refined operation, and, above all, very favorable fuel consumption.
• Ergonomic AGR seats: In higher trims, it was possible to get front seats certified by the German association for healthy backs (Aktion Gesunder Rücken). These offer a wide range of adjustments and excellent support, which you will appreciate especially on long journeys.

Mazda 3

Advantages:

• Superb driving characteristics and steering: The Mazda 3 is renowned for its chassis, which offers excellent feedback and agility, especially appreciated by enthusiastic drivers.
• Refined and reliable naturally aspirated engines: Unlike most of the competition, it relies on Skyactiv-G naturally aspirated engines, which are known for their reliability, smooth operation, and pleasant throttle response.
• Premium design and interior quality: The car's interior feels very high-end thanks to the use of quality materials, a minimalist design, and excellent driver-focused ergonomics.

Disadvantages:

• Limited space in the rear seats: Especially in the hatchback, legroom and headroom for rear passengers are below average.
• Smaller luggage compartment volume: The hatchback offers only 351 liters, which is small compared to the competition. The sedan is better off with 450 liters.
• Poorer visibility from the car: The design with a massive C-pillar on the hatchback and generally lower windows restricts visibility, especially diagonally to the rear.
• Higher purchase price: In comparable trims, the Mazda 3 is often more expensive than the Peugeot 308.

Peugeot 308

Advantages:

• Attractive and original design: The Peugeot 308 features sharp lines, a distinctive grille, and a light signature, making it one of the most striking cars in the segment.
• Generous luggage space: The hatchback offers an above-average 412 liters, and the SW estate version offers a whopping 608 liters, which is a top-class value.
• Modern interior with i-Cockpit: The layout with a small steering wheel and raised digital instruments has a futuristic and sporty feel.
• Comfortable and quiet chassis: The chassis is tuned primarily for comfort, filtering out bumps well and ensuring a quiet ride.
• Wide range of powertrains: Efficient petrol and diesel engines are available, as well as two plug-in hybrid and a fully electric variant.

Disadvantages:

• Specific i-Cockpit ergonomics: The small steering wheel and the view of the gauges over it may not suit every body type.
• Slower infotainment system response: The multimedia system can sometimes be slow, and its operation takes some getting used to.
• Limited rear headroom: The sloping roofline can limit headroom for taller passengers in the back seats.
• Less communicative steering: The steering doesn't offer as much feedback as the Mazda 3, which may bother more sport-oriented drivers.

What to Watch Out For: A Comparison of the Most Common Problems

Based on our own CarAudit inspections, breakdown statistics, and service data, we have compiled an overview of the most common problems that used car buyers should watch out for. While both cars are considered reliable, their weaknesses lie in completely different areas.

Mazda 3 (BP generation, from 2019)

The fourth-generation Mazda 3 maintains its reputation as a very reliable car and does not suffer from any fatal design flaws. Most of the recorded problems relate to electronics or have been addressed through recalls.

• Electronics and infotainment: The most common owner complaints are directed at the Mazda Connect infotainment system. It can occasionally freeze, restart on its own, or become unresponsive to touch. The problem is often solved by a software update or a hard reset of the system (by holding down the NAV, Mute, and Back buttons simultaneously for 10 seconds).
• Driver-assistance systems: The first model years (2019) were affected by a recall for the Smart Brake Support system, which could activate without reason. For a used car, it is crucial to verify with an authorized service center that this action has been performed.
• Engine and chassis: The naturally aspirated Skyactiv-G engines are considered exceptionally reliable. The only weakness is a tendency for the engine oil to be diluted with gasoline during frequent short trips when the engine doesn't fully warm up. Some owners have also noted a clicking sound from the high-pressure fuel pump, but this is considered a normal operating characteristic of a direct-injection engine. There were also factory recalls for insufficiently tightened wheel nuts, which is now rare in used cars, but a thorough technical inspection of the car is always advisable.
• Transmission: With automatic transmissions, jerky shifting can rarely occur, especially in cars from 2019. Regular transmission fluid changes are key to a long service life here.

Summary for Mazda: The Mazda 3's problems are more minor and electronic in nature. The mechanical foundation is very robust. A careful, comprehensive vehicle inspection focusing on recall history and electronics functionality is the ideal way to secure a trouble-free car.

Peugeot 308 (generations II and III, from 2013)

With the Peugeot 308, the situation is more complex and depends heavily on the specific engine and year of manufacture. While the BlueHDi diesel engines are considered reliable, extra caution is needed with the gasoline units.

• 1.2 PureTech engine (until 2022): This is the most discussed and riskiest point of the second-generation 308. These engines use a timing belt that runs in oil. Using the wrong oil, extending service intervals, or making frequent short trips leads to the degradation of the belt. Its loose particles can clog the oil pump's intake strainer, leading to a drop in lubrication pressure and, in the worst case, fatal engine damage. Cars manufactured after 2020 used a more durable version of the belt. The new generation (from 2022) has switched to a timing chain.
• 1.5 BlueHDi engine: Even the reliable diesels have not been without problems. A recall concerned the timing chain (connecting the camshafts), which could break due to oil carbonization. Again, it is necessary to check the service history and participation in the recall.
• Electronics and infotainment: Similar to the Mazda, the touchscreen and onboard systems can occasionally act up. Start-Stop system problems are often related to an aging battery or faulty sensors. Users also sometimes complain about a non-functional air conditioning system or key recognition issues.
• Chassis: Play can develop in the front axle stabilizer links, which manifests as a knocking sound when driving over bumps. This is not an expensive but a relatively common fault.

Summary for Peugeot: The riskiness of a Peugeot 308 hinges on the choice of engine. While it's a good choice with a diesel engine and a verified service history, an independent inspection of the car's technical condition is an absolute must for the 1.2 PureTech gasoline engine. Overall, the Peugeot is more prone to numerous minor issues, as well as a few potentially very serious mechanical problems.

When buying a used car, a thorough inspection is key, and neither of these models is an exception. Although both are considered relatively reliable, each has specific areas to focus on to prevent expensive repairs. An independent comprehensive vehicle inspection is always the best guarantee.

When choosing a Mazda 3

The fourth-generation Mazda 3 (designated BP, produced from 2019) has a reputation as a reliable car, but it's still a good idea to pay attention to a few details.

• Automatic transmission operation: On models from the first years of production (especially 2019), there were occasional complaints about jerky shifting or delayed responses. During a test drive, try both smooth starts and harder acceleration, and watch to see if the transmission shifts smoothly and without hesitation.
• Chassis condition and wheel noise: Some owners have reported premature wear of shock absorbers or wheel bearings. While driving over bumps, listen for any knocking or rumbling sounds from the axle area. A humming noise at higher speeds can also indicate a problem with the bearings.
• Infotainment Functionality: The Mazda Connect system is generally reliable, but make sure that all functions, including navigation, Bluetooth connectivity, and Apple CarPlay/Android Auto, work without freezing or restarting. Also, check the display for any dead pixels.
• Engine and Starting: The naturally aspirated Skyactiv-G engines are considered very durable, but they are sensitive to oil quality and regular changes. Check the service history. During a cold start, listen for any unusual rattling sounds from the engine, which could indicate a problem with the timing chain.
• Battery and Start-Stop System Check: On cars equipped with the i-ELOOP and Start-Stop system, the original 12V battery may be nearing the end of its life after a few years, which manifests as irregular function of the Start-Stop system. Verify that the system is working correctly.

When choosing a Peugeot 308

The second generation Peugeot 308 (T9, produced from 2013–2021) is a popular used car, but it requires careful selection, especially regarding its engines and electronics.

• The 1.2 PureTech Engine and its Service History: This award-winning engine has a specific design with a wet timing belt (belt-in-oil). It is absolutely crucial to verify that the precisely prescribed type of oil was used and that changes were carried out on time (ideally sooner than the prescribed intervals). Using the wrong oil can lead to the belt disintegrating, clogging the oil pump, and causing fatal engine damage. Listen for any rattling after starting the engine.
• Behaviour of the EAT6/EAT8 Automatic Transmission: The Aisin transmissions are generally reliable but require regular oil changes (ideally every 60,000 km). During a test drive, check that the transmission shifts smoothly, without any jerking or hesitation, during both calm and more dynamic driving.
• Touchscreen and Electronics Functionality: Older versions of the SMEG+ multimedia system can be slower or occasionally freeze. Thoroughly test all functions – from the air conditioning and navigation to the parking sensors. Check that no error messages are displayed on the instrument cluster.
• AdBlue System in BlueHDi Diesel Engines: In diesel versions, the urea injection system (AdBlue) is a common source of problems. A pump or tank failure can mean an expensive repair. Check the service history to see if the system has been repaired before, and during your drive, watch for any emission-related errors from the onboard computer.
• Condition of the Rear Axle: Although it has a simple design, cars with higher mileage can have worn bushings or bearings, which manifests as noise or slight instability from the rear of the car when driving over bumps. Any physical inspection of a used car should include checking the undercarriage on a lift.
