The Best Year of the Audi A5: What Shoppers Should Really Look For

The Audi A5’s best all‑around model year for most used buyers is widely considered to be the 2018 Audi A5, thanks to its full redesign, improved engine and tech, stronger reliability record, and balanced value—but depending on budget and priorities, 2016 and 2021–2023 models are also standout choices. This article explains how the A5 has evolved, what makes 2018 such a sweet spot, and which other years are worth targeting or avoiding.

Why “Best Year” Is Complicated for the Audi A5

Asking for the single best year of the Audi A5 sounds like it should have one definitive answer, but the reality is more nuanced. The “best” year depends heavily on your priorities: reliability, performance, tech features, design, or value for money. The A5 has gone through three major generations (2008–2016, 2018–2024) with a gap/transition in 2017 for some markets, and each period brought improvements—as well as some known trouble spots.

Generational Overview

Understanding the broad generational changes helps explain why some model years are more desirable than others and why 2018 often emerges as the most balanced pick.

The main generations of the modern Audi A5 are typically described as follows:

• First generation (B8/B8.5, 2008–2016): Classic coupe styling, strong build quality, but earlier years have more mechanical issues and dated tech by modern standards.
• Second generation (B9, 2018–2023 in North America): Major redesign with new engines, upgraded MMI infotainment, better driver-assistance features, and reduced reported problems compared with early B8 cars.
• Latest updates (2021–2023 refreshes): Sharper styling, MMI touchscreens standard, more safety tech, but higher prices on the used market and more software complexity.

This evolution means that while early A5 models have enthusiast appeal, the later B9 cars—and especially 2018—tend to offer the best mix of modern tech, performance, and reliability at reasonable used prices.

Why the 2018 Audi A5 Is Often the Best Overall Year

The 2018 Audi A5 is frequently recommended by reviewers, used-car analysts, and owner communities as the optimal balance of new-generation improvements and used-market value. It debuted the B9 platform for the A5 in North America, bringing meaningful advancements over the outgoing B8.5.

Major Redesign and Platform Improvements

The 2018 model year introduced the second-generation A5 to the U.S. and many other markets, offering a more modern driving experience and cabin than the outgoing car without the teething issues often seen in brand-new models.

Some of the key platform-related benefits of the 2018 A5 include:

• Lighter and stiffer chassis: Improved handling, ride comfort, and fuel economy compared with the previous generation.
• Updated 2.0 TFSI engine: Around 252 hp in most markets, smoother and more efficient than earlier 2.0T versions, with fewer widespread complaints than early-2010s engines.
• Modern transmission pairings: Seven-speed dual-clutch (S tronic) or eight-speed automatic on some variants, providing quick shifts and good highway economy.
• Improved NVH (noise, vibration, harshness): Quieter cabin and more refined ride, making the car feel more premium on long drives.

Taken together, these upgrades make the 2018 A5 feel like a thoroughly modern luxury coupe, Sportback, or cabriolet rather than a dressed-up older platform.

Tech, Infotainment, and Driver Assistance

The 2018 redesign also marked a major leap forward in technology, addressing one of the biggest drawbacks of older A5s: dated infotainment and limited driver assist features.

Notable tech and safety improvements on the 2018 A5 include:

• Updated MMI interface: Crisper graphics, quicker response, and more intuitive menu layouts versus B8/B8.5 models.
• Available Virtual Cockpit: Fully digital instrument cluster with map integration and configurable layouts (on many Premium Plus and Prestige trims).
• Enhanced driver-assistance systems: Options like adaptive cruise control with traffic jam assist, lane-keeping aids, and improved collision avoidance tech.
• Better smartphone integration: Availability of Apple CarPlay and Android Auto on many trims and markets, pending exact spec.

These features substantially narrow the gap between a 2018 A5 and much newer cars, which is why many buyers find it the best value point in the lineup.

Reliability and Ownership Costs

Independent reliability reports and owner feedback suggest that by 2018, Audi had resolved many of the chronic issues that affected some earlier A5 model years, particularly with oil consumption and certain engine components on early 2.0T engines.

From a reliability and cost-of-ownership standpoint, 2018 often stands out because:

• Post-early-engine issues: The redesigned 2.0 TFSI is generally less prone to severe oil consumption problems that plagued some 2009–2012 cars.
• Fewer age-related failures: A 2018 is new enough that large-scale age-related repairs (suspension overhauls, interior electronics degradation) are less common, assuming reasonable mileage.
• Parts and independent service availability: The B9 platform is now well-known to independent shops, potentially lowering maintenance costs compared to when it was brand-new.
• Depreciation curve: By now, many 2018 A5s have already taken a significant depreciation hit, offering more car for the money than equivalent newer models.

No used European luxury car is cheap to maintain, but 2018 often offers a favorable compromise between modern engineering and manageable long-term costs.

Other Strong Audi A5 Model Years to Consider

While 2018 is a standout, it’s not the only smart choice. Depending on budget, styling preferences, and appetite for technology, several other years are worth close attention.

2016 Audi A5: The Best of the First Generation

The 2016 Audi A5 represents the final year of the first-generation B8.5 platform in many markets and is often praised as the best “classic” A5 year for those who like the original shape and want a more analog-feeling car with simpler tech.

Key advantages of the 2016 A5 include:

• End-of-cycle refinement: Many early bugs from the generation had been addressed by this point.
• More mature reliability record: By 2016, the engines and transmissions had been in service long enough for most serious design flaws to be addressed via TSBs and recalls.
• Often lower purchase price: Typically cheaper than a 2018+ while still offering a premium feel and timeless styling.
• Less complex tech: Fewer advanced electronics and driver aids mean fewer potential high-tech failures down the road.

For buyers who prefer a more analog aesthetic, don’t need the latest infotainment, and want to stay on a strict budget, a well-maintained 2016 A5 can be a very smart pick.

2021–2023 Audi A5: Best for Cutting-Edge Tech and Safety

Buyers with bigger budgets and a desire for the latest features may find the refreshed 2021–2023 A5 lineup more appealing. These models refine the B9 formula introduced in 2018, adding updated software, styling tweaks, and often more standard equipment.

Notable strengths of the 2021–2023 A5 models include:

• Updated MMI Touch: Larger touchscreen interfaces replacing the rotary controller on many trims, with improved connectivity and software.
• More standard safety features: In many regions, advanced driver-assistance systems became standard or more widely available across trims.
• Fresh design details: Sharper exterior styling, updated lighting signatures, and fresher interiors.
• Lower mileage on average: Being newer, these cars often have fewer miles, appealing for long-term ownership.

If budget allows and you want a nearly current-gen experience, these model years sit near the top of the list—though they are typically more expensive than an equivalent 2018 and may come with higher insurance and tax costs depending on your location.

Audi A5 Years to Approach More Carefully

Not every A5 year is equally appealing from a reliability and cost standpoint. While many older cars can be excellent if meticulously maintained, some model years are riskier for buyers without the appetite for higher repair bills.

Early Years: 2008–2012

The earliest A5s helped establish the model’s reputation for design and driving pleasure, but they also brought a number of issues typical of first-generation vehicles and early versions of an engine family.

Common concerns with 2008–2012 A5s include:

• 2.0T oil consumption problems: Some early engines are known for burning excessive oil, sometimes requiring expensive engine work or rebuilds.
• Carbon buildup: As with many direct-injection engines, intake valve carbon buildup can affect performance over time.
• Aging electronics: Older MMI systems and electrical components can become failure points as these cars age.
• Suspension and wear items: With age and mileage, control arms, bushings, and other suspension components may need replacement.

Enthusiasts with strong mechanical support or a willingness to invest can still enjoy these cars, but they are generally not the safest pick for buyers prioritizing low running costs and hassle-free ownership.

2013–2015: Mid-Cycle B8.5 Options

The 2013–2015 A5s, part of the B8.5 facelift, are often more reliable than the very early cars, but they occupy an awkward middle ground: old enough to be dated in tech and style, yet not as cheap as the oldest models nor as advanced as the 2018+ generation.

Key considerations for 2013–2015 models include:

• Improved but still older tech: Better than pre-facelift, but lacking modern smartphone integration and driver-aid sophistication.
• Variable maintenance histories: This age bracket depends heavily on previous owners’ care and documentation.
• Depreciation plateau: Prices may not be low enough to fully compensate for the lack of modern features versus a 2018.
• Regional variability: Some markets received slightly different engine calibrations and option packages, affecting desirability.

These cars can be good buys if clean and well-documented, but for many shoppers, spending a bit more to reach 2016 or 2018+ brings disproportionately better value.

How to Choose the Best Audi A5 Year for Your Needs

The best year of the Audi A5 for one buyer may differ from another’s, depending on how they balance cost, reliability, and features. Rather than chasing a single perfect answer, it helps to match specific years to specific buyer profiles.

Key Factors to Weigh

When deciding which A5 year is best for you personally, a few practical criteria should guide the choice beyond the reputation of a given model year.

Consider the following when choosing an A5 model year:

• Budget: How much you can spend upfront, and how much you’re willing to reserve for maintenance and repairs.
• Desired tech level: Whether you need modern infotainment, CarPlay/Android Auto, and advanced driver aids, or can live with older systems.
• Reliability tolerance: Whether you can handle potential repairs on an older, higher-mileage car or prefer a newer, lower-risk option.
• Body style: Coupe, Sportback, or cabriolet availability varies by year and market; some years are stronger for certain body styles than others.
• Ownership horizon: If you plan to keep the car many years, newer models (2018+) often make more sense; short-term owners may be fine with older, cheaper examples.

Matching these considerations with the strengths of particular years—such as 2016 for a refined first-gen car or 2018 for a well-rounded B9—usually leads to a better outcome than searching for a single “magic” year.

Conclusion: Why 2018 Stands Out—and When to Look Elsewhere

For most modern used-car shoppers, the 2018 Audi A5 is the standout year: it introduced the current-generation B9 platform, significantly upgraded tech and safety, improved drivetrain refinement, and has now reached a used price point that offers strong value without being so new that you pay nearly-new premiums.

However, the best year can shift depending on priorities:

• Value and modernity: 2018 is typically the ideal sweet spot.
• Classic first-gen feel and lower purchase price: 2016 is a strong, relatively safe choice.
• Latest tech and lowest mileage: 2021–2023 are top-tier if your budget allows.
• Budget builds or enthusiast projects: Carefully chosen early years (2008–2012) can work, but demand thorough inspection and realistic expectations.

In practice, a pre-purchase inspection by a trusted Audi‑savvy mechanic, a full service history, and a realistic maintenance budget matter just as much as picking the “right” year on paper.

Summary

Across the Audi A5’s history, the 2018 model year is widely regarded as the best all-around choice for most used buyers, thanks to its full redesign, improved powertrain, modern infotainment, and solid reliability for the segment. The 2016 A5 is the standout of the first generation, while 2021–2023 models are best for those seeking the latest tech and are willing to pay more. Earlier years can still be rewarding but come with higher mechanical and aging-related risks, making careful inspection and documentation crucial. Ultimately, the ideal A5 year depends on your budget, tech expectations, and tolerance for maintenance, with 2018 offering the most compelling overall balance.
