Overview

Quick Facts You Can Trust About this Model

• The i20’s boot capacity is an impressive 352 liters, significantly larger than the Ford Fiesta (292 liters) and even beating the VW Polo (351 liters).
• All post-2021 models feature wireless Android Auto and Apple CarPlay as standard, a feature that was optional on many premium rivals at the time.
• Despite its small size, the i20 offers exceptional rear passenger space, with 882mm of legroom – more than several vehicles in the class above.
• The 2020-2024 i20 was the first Hyundai supermini to incorporate 48V mild-hybrid technology, improving fuel efficiency by up to 4%.
• Upper trim levels come with a 10.25-inch digital instrument cluster and matching infotainment screen—technology normally found in cars costing significantly more.

How Does It Stand Out Compared To The Previous Models?

The third-generation i20 (2020-2024) represents a quantum leap from its predecessor. While the previous generation played it safe with conservative styling and basic tech, this version makes a much bolder statement. The exterior dimensions grew slightly, resulting in significantly more interior space—rear passengers get extra knee room and the boot increased from 326 liters to a class-leading 352 liters. 

Technology took a major step forward with the introduction of a 10.25-inch digital display (standard on higher trims), advanced driver assistance systems like lane keep assist and autonomous emergency braking, and enhanced connectivity options that were merely optional extras in the previous model.

The 2020-2024 model also introduced the 48V mild-hybrid technology, marking a clear efficiency improvement over its predecessor. Interior quality noticeably improved with better materials and a more contemporary design, though some hard plastics remain.

The most recent model launched in late 2024 pushes even further upmarket with a larger touchscreen as standard, improved driver assistance features, and a more premium interior with sustainable materials. The latest model also introduced a full hybrid powertrain option with improved fuel economy of 60+ mpg—something the 2020-2024 generation never offered.

In short: while the second-generation i20 was merely competent transportation, the 2020-2024 model established itself as a genuine competitor to class leaders, with the newest generation now pushing boundaries in technology and efficiency. Each generation represents clear progress, though unsurprisingly with an accompanying price increase.

Which Model In This Generation Stand Out?

The 2022 Premium trim with the 1.0 T-GDi mild-hybrid engine is the sweet spot in the range. By this point, Hyundai had resolved most of the early infotainment and electrical niggles that affected some 2020 models. This combination delivers the best balance of equipment, performance, and value without the premium price of the Ultimate trim.

For high-mileage drivers, the same 1.0 T-GDi engine in Premium trim represents the optimal choice, offering excellent fuel economy of around 50 mpg in real-world conditions while providing sufficient power (100 PS) for comfortable motorway cruising. Just be wary of very early (2020) models which occasionally suffered from electrical issues and infotainment glitches that were largely resolved in later production runs.

Potential Issues To Be Aware Of

Watch out for these potential problems when buying a 2020-2024 Hyundai i20:

• Infotainment system issues are the most commonly reported problem, particularly in early models. Symptoms include screen freezes, connectivity problems with Android Auto/Apple CarPlay, and occasional system reboots. Many of these were resolved with software updates, so ensure any used example has had all updates applied.
• Some owners report electrical glitches affecting the stop-start system and occasionally causing dashboard electronics to reset. This appears more common in early (2020-2021) production models.
• The dual-clutch automatic transmission (DCT) can sometimes hesitate when pulling away from a stop. This is generally a characteristic rather than a fault, but excessive hesitation might indicate maintenance issues.
• While generally solid, the 48V mild hybrid system has occasionally been reported to generate fault codes. These are typically resolved with software updates rather than component replacement.

Word to the wise: always check for a complete service history, as these cars benefit significantly from regular maintenance. Pay particular attention to whether all software updates have been completed, especially for models with reported tech issues.

Performance

Engine Line Up

The 2020-2024 Hyundai i20 offers a streamlined engine range focusing on efficiency without sacrificing performance. The standout powertrain is the 1.0-liter T-GDi turbocharged three-cylinder petrol engine paired with 48V mild-hybrid technology, producing either 100 PS or 120 PS depending on the variant.

The more popular 100 PS version delivers balanced performance with a 0-62mph time of 10.4 seconds when paired with the six-speed manual transmission (11.4 seconds with the seven-speed dual-clutch automatic). This provides sufficient punch for urban driving while remaining composed on motorways.

For those seeking more spirited performance, the 120 PS variant reduces the 0-62mph sprint to a more engaging 10.1 seconds when equipped with the manual gearbox. This puts it ahead of many competitors in its class, offering a surprisingly enthusiastic response when pushed.

Petrol Power

Throughout this generation, the 1.0 T-GDi engine has been the mainstay of the range, with the mild-hybrid technology added to improve efficiency rather than outright performance. The engine delivers 172 Nm of torque at just 1,500 rpm, providing excellent low-end pull that makes city driving and overtaking remarkably effortless for a small car.

The three-cylinder setup is generally smooth, though there’s a characteristic thrum under hard acceleration that adds character without becoming intrusive. The mild-hybrid system contributes additional torque when accelerating and allows for smoother, more efficient stop-start functionality in urban traffic.

The intelligent Manual Transmission (iMT) deserves special mention – it features a clever clutch-by-wire system that allows the engine to disconnect during coasting, improving fuel economy by around 3-4% compared to a traditional manual setup.

Handling & Ride

For a 2020-2024 supermini, the i20 handles with composed confidence rather than outright sportiness. The steering is direct and well-weighted, though it lacks the communicative feel of a Ford Fiesta. All models come with front-wheel drive, delivering predictable handling characteristics even in challenging conditions.

The six-speed manual transmission offers a precise, if slightly notchy, shift action. The seven-speed dual-clutch automatic provides smooth gear changes once rolling, though there can be a momentary hesitation when pulling away from a standstill – a common characteristic of DCT gearboxes rather than a fault.

Comfort

Across this generation, ride quality strikes a good balance between comfort and control. The i20 absorbs urban imperfections well, though larger potholes can occasionally cause a thump to be felt through the cabin. On smoother roads and motorways, the car feels settled and composed.

Road and wind noise are well suppressed for a car in this class, with engine noise only becoming noticeable under hard acceleration. The seats provide good support for longer journeys, though some taller drivers may find the driving position slightly compromised due to limited steering wheel adjustment range.

Reliability

Why You Can Trust This Car?

The 2020-2024 Hyundai i20’s core structure demonstrates excellent durability, with several key components showing impressive reliability. The 1.0 T-GDi petrol engine has established itself as particularly robust, with many examples now reaching 50,000+ miles without significant mechanical issues.

The bodywork holds up exceptionally well against corrosion, and paint quality remains strong even in older examples. Interior materials show good resistance to wear, with the seat fabrics and touchpoints maintaining their quality even in high-mileage cars.

Basic mechanical components like the manual transmission, suspension system, and braking hardware demonstrate solid reliability. The LED lighting systems (standard on higher trims) rarely give trouble, and the climate control system generally maintains good performance with regular servicing.

The 48V mild-hybrid system has proven surprisingly trouble-free – a positive note given the additional complexity it introduces. Even the electronic systems, often a weak point in modern cars, have proven largely dependable in post-2021 examples after early software updates addressed initial niggles.

Regular maintenance costs typically range from £169 for basic services to around £279 for major services – very reasonable for a modern supermini with mild-hybrid technology. The five-year, unlimited-mileage warranty provides excellent peace of mind for used buyers of newer examples. 

What Rarely Goes Wrong?

Based on owner experiences and reliability data, the engine, manual transmission, suspension, braking system, and chassis components rarely experience significant issues in the 2020-2024 Hyundai i20 when properly maintained.

The most commonly reported problems center around the infotainment and connectivity systems rather than mechanical components. Major mechanical failures are uncommon, reflecting Hyundai’s improved build quality in this generation.

Is This The Most Reliable In This Generation?

The 2020-2024 i20 shows distinctly different reliability patterns across its production run. Early models (2020-2021) suffered from some teething troubles, primarily with electronic systems, infotainment connectivity, and occasional electrical gremlins. These were less dependable than expected at launch.

However, the story changes significantly with models produced from mid-2021 onward. These later versions demonstrate markedly improved reliability after Hyundai implemented a series of software updates and minor production changes. Owner surveys show significantly fewer reported issues with these updated models.

When compared to the previous generation (2014-2020), this newer i20 is more technologically advanced, which introduces more potential points of failure. However, the core mechanical components are generally more robust, and the overall ownership experience tends to be more positive once the early issues were resolved.

How Does The i20 Long-Term Reliability Compare At High Mileage (100k+) Versus Low Mileage?

The i20 shows interesting reliability patterns as the miles accumulate. Low-mileage examples (under 40,000 miles) typically face mostly electronic and software-related issues – particularly infotainment glitches and connectivity problems. These tend to surface early if they’re going to appear at all, making them relatively predictable.

As mileage increases toward the 60,000-80,000 mark, the picture remains surprisingly positive. The 1.0 T-GDi engine maintains good performance and efficiency, though some owners report slightly increased oil consumption – not unusual for a small turbocharged engine. The manual transmission continues to perform well, while the DCT automatic may require more attentive maintenance.

While few examples have yet reached the 100,000+ mile mark, early indications from fleet users suggest the i20 maintains good mechanical integrity. The 48V mild-hybrid system appears to be holding up well, without the battery degradation issues some predicted. However, suspension components – particularly front struts and bushings – typically require attention around this mileage, with replacement costs around £300-£400 per side.

Real Ownership Experience

Here is the total ownership cost breakdown for the Hyundai i20 (2020-2024):

Holding Its Value?

The Hyundai i20 demonstrates above-average value retention in the supermini sector, making it a smart financial choice for used car buyers concerned about future depreciation.

A well-maintained 2020-2024 i20 typically retains about 61-65% of its value after three years, which compares favorably to mainstream rivals like the Ford Fiesta (58-60%) though falling short of the VW Polo (63-67%). Higher-specification models tend to hold their value better than entry-level variants.

Looking at specific examples: A 2021 i20 Premium with the 1.0 T-GDi engine, originally costing around £20,000, now sells for approximately £13,000-£14,000 on the used market – that’s a 65-70% value retention over three years. The mild-hybrid models tend to command a slight premium, particularly as fuel economy becomes increasingly important to buyers.

Models with the technology pack and higher trim levels like Premium and Ultimate hold their value particularly well, as buyers increasingly prioritize connectivity features and advanced driver assistance systems.

The Cheapest Models To Maintain

The 2021-onwards 1.0 T-GDi SE Connect with manual transmission stands out as the most cost-effective i20 to run and maintain. It makes financial sense because of several key factors:

• The manual transmission avoids the additional complexity and potential maintenance costs of the DCT automatic
• It includes the essential equipment most buyers want without the costly extras of higher trims
• Parts are widely available and reasonably priced compared to premium rivals
• Excellent fuel economy of 50+ mpg in real-world driving
• The robust engine design has proven reliable with simple maintenance requirements

While higher trims offer more features, they include additional electronic components that potentially increase repair costs outside warranty coverage. The sweet spot balances equipment levels with maintenance simplicity.

What Is The Typical Lifespan Of Major Components (Transmission, Engine, Electrical Systems)?

What are the most expensive common repairs reported by owners?

Drawing from real i20 owners’ experiences, there are several noteworthy repair costs to be aware of. As one owner explained:

“The i20 is generally reliable, but when things do go wrong, it’s usually electronics rather than mechanical components.”

The dual-clutch transmission (DCT) mechatronics unit tops the expense list, with repairs costing £800-£1,200 if problems develop outside warranty period. As a Reddit user noted:

“The DCT works great most of the time, but when issues arise, it’s not a DIY fix. Dealer diagnostics alone cost me £120.”

Infotainment system failures represent another potential expense, particularly in early models. Complete unit replacement can cost £800-£1,000, though many issues can be resolved with software updates that dealers sometimes perform free of charge.

The 48V mild-hybrid system’s battery pack represents a potential future expense for higher-mileage examples, though replacements have been rare so far. When required, expect costs around £500-£700.

For models with advanced driver assistance systems, the front radar sensor can occasionally fail, with replacement and calibration costing approximately £600-£850.

Which Model In This Generation Has The Lowest Depreciation?

Looking for the i20 that’ll best protect your investment? The 2021-2022 Premium and Ultimate models with the 1.0 T-GDi mild-hybrid powertrain are your best bet. These versions hold approximately 65-68% of their value after three years – significantly better than the class average of 58-60%.

The Premium trim with the 1.0 T-GDi engine is particularly sought after, as it hits the sweet spot of desirable features, good performance, and reasonable running costs without the premium price of the Ultimate model. It includes the 10.25-inch infotainment system, LED headlights, and heated front seats – features that used buyers specifically seek out.

Colours also impact depreciation, with solid white and gray metallic maintaining value best, while more distinctive colors like Intense Blue and Dragon Red can be more polarising on the used market.

Competitors

The Hyundai i20 (from £17,820 new, used from £11,500) sits in an interesting position in the UK supermini market, competing with both mainstream and premium rivals.

On the mainstream side, it goes up against the Ford Fiesta (though now discontinued, still abundant on the used market), the value-packed Vauxhall Corsa, and the stylish Peugeot 208. Its cousin from the Hyundai Group, the Kia Rio, shares many mechanical components but offers a slightly different take on the formula.

When buyers look upmarket, the i20 is often cross-shopped against the VW Polo and SEAT Ibiza, though these typically command a price premium for their perceived superior build quality and badge prestige.

Living With the Car

How Is The Build Quality Of The Hyundai i20 2020-24

The 2020-2024 i20 demonstrates Hyundai’s significant progress in build quality, though with some areas for improvement. The cabin materials feel modern with a good mix of soft-touch plastics on the dashboard and doors, though harder plastics remain in less visible areas. Panel fit and consistency are generally good, with minimal rattles developing even in higher-mileage examples.

Post-2021 models show particular improvement, with better electronics reliability and more consistent assembly quality. The fundamental structure is notably solid—suspension components and body integrity hold up well even in high-mileage examples.

While not quite matching the VW Polo’s tank-like solidity, the i20’s build quality is a definite step above the previous generation and compares favorably with most mainstream rivals. The key advantage is consistency—even after 40,000+ miles, these cars typically maintain their solid feel with minimal deterioration, provided they’ve been maintained properly.

Most Comfortable Features

The i20 excels in everyday comfort, particularly in higher-specification models. The supportive front seats with good lumbar support make longer journeys less tiring, while the sliding rear seats offer excellent legroom for passengers—a standout feature in this class. The climate control system (standard on Premium and Ultimate trims) effectively maintains cabin temperature and includes rear vents—a feature many rivals charge extra for or don’t offer at all.

Ride comfort is best on the 16-inch wheels, where the i20 smoothly handles most road imperfections. The 17-inch wheels on top models look more stylish but do transmit more road texture into the cabin. The interior is notably quiet at motorway speeds, with good insulation from wind and road noise—though the three-cylinder engine has a distinctive thrum when pushed hard.

We asked our Tiguan customers to describe how comfortable their Tiguan is and they came up with the following:

Suspension And Ride Quality

The i20’s suspension system shows good durability, though its ride quality varies noticeably depending on wheel size and road conditions. Most owners report the first signs of suspension wear around 45,000-50,000 miles, typically starting with front strut mounts becoming noisier over rough surfaces. The rear torsion beam setup tends to last longer, often going beyond 70,000 miles without issues.

Common aging signs include increased road noise over bumps and slight creaking from the suspension components, particularly noticeable on models with larger wheels. However, it’s worth noting that the overall suspension design prioritizes comfort over sporty handling, which helps preserve component longevity.

Does It Deteriorate Over Time?

The suspension system is actually quite robust, but it’s the bushings and dampers that need attention first. Regular maintenance makes a huge difference—a well-cared-for i20 at 60,000 miles often rides better than a neglected one at half that mileage. The front anti-roll bar links tend to be the first components requiring replacement, typically around 40,000-50,000 miles, with replacements costing approximately £120-£150 including labor.

How Good Is It For Families?

The i20 excels as a family car despite its supermini designation, with several parent-friendly features that make daily life easier. The generous 352-liter boot easily swallows a folding stroller and weekly shopping, while the rear doors open wide enough to make fitting child seats straightforward. The ISOFIX points are easily accessible, and the rear-seat space is among the best in class—easily accommodating bulky child seats without forcing front passengers to compromise their position.
