Used Audi A5 Mk1 (2007-2016) Buyer’s Guide: Performance, Value

The first-generation Audi A5, produced from 2007 to 2016, redefined the luxury coupe segment with its elegant design, refined engineering, and balanced driving experience. Available as a coupe, cabriolet, and later Sportback, this Mk1 model appeals to buyers seeking a premium used car that combines visual appeal with practical performance. While rivals like the BMW 4 Series offer sharper handling, the A5 excels in grip, comfort, and build quality, making it a smart choice on the second-hand market.

Design and Body Styles: Timeless Elegance

Audi’s A5 Mk1 stands out for its sweeping lines and proportions that prioritize style without sacrificing usability. The coupe version, launched in 2007, features a low-slung roofline and frameless doors, creating a sporty silhouette ideal for those who value aesthetics. The cabriolet followed soon after, offering open-top motoring with a power-folding fabric roof that operates smoothly even at low speeds.

In 2009, the Sportback arrived, blending hatchback practicality with coupe-like flair. Its extended roof and small tailgate provide more cargo space—up to 480 liters—while maintaining the A5’s sleek profile. All body styles share high-quality materials and precise panel gaps, contributing to the model’s reputation for superb construction.

• Coupe: Purest form, best for two-up cruising.
• Cabriolet: Adds wind-in-hair fun, suitable for four.
• Sportback: Most versatile, with family-friendly rear space.

Engine Lineup: Powertrains for Every Need

The A5 Mk1 offered a diverse range of petrol and diesel engines, catering to efficiency-focused commuters, performance enthusiasts, and long-distance drivers. Diesel options dominate recommendations for their torque, refinement, and economy, while petrol variants suit those preferring smoother revs.

Diesel Engines: The star is the 2.0-liter TDI, available in 159bhp and 173bhp tunes. The stronger version accelerates from 0-62mph in 8.2 seconds, with a refined hum under load and quiet idle. Even the Ultra model’s detuned 159bhp unit hits 0-62mph in 8.3 seconds manually or 7.8 seconds with the automatic, without major efficiency trade-offs. Official economy reaches 55mpg for front-wheel-drive manuals, dropping to 51mpg with quattro and auto.

Higher up, the 2.7-liter TDI pairs with a CVT multitronic gearbox, delivering around 42mpg. The potent 3.0-liter V6 TDI, standard with quattro, boasts 328bhp (post-2011) for a 5.8-second 0-62mph sprint, though running costs rise due to its thirst and complexity.

Petrol Engines: Entry-level 1.8 TFSI (168bhp) manages 0-62mph in 7.9 seconds and 39mpg. The 2.0 TFSI (211-225bhp) quattro improves to 6.4 seconds but sacrifices fuel efficiency. Premium S5 models feature a 3.0 TFSI supercharged V6 (329bhp, 4.9 seconds) or earlier 4.2 V8 (349bhp).

The RS5 coupe crowns the range with a 4.2-liter V8 producing 444bhp, achieving 0-62mph in 4.5 seconds via dual-clutch auto, topped at 174mph—though at 26mpg.

Transmission Options: Smooth and Responsive

Audi paired engines thoughtfully with gearboxes. Manuals suit the 1.8 TFSI and base 2.0 TDI for engaging shifts. The multitronic CVT on 2.7/3.2 models simulates steps for natural feel. From 2008, the S tronic dual-clutch auto revolutionized the lineup, offering lightning shifts and paddle control—essential for quattro models and boosting acceleration.

Tiptronic autos appear on early V8 S5s, while later S5/RS5 use seven-speed S tronic for track-ready precision.

Driving Experience: Grip Over Agility

Behind the wheel, the A5 prioritizes composure. Quattro all-wheel drive delivers phenomenal traction, especially in wet conditions, with minimal cornering lean thanks to well-damped suspension. Front-wheel-drive models remain planted and enjoyable, though less planted than AWD.

Steering is precise but lacks the BMW 4 Series’ raw feedback, feeling more insulated. Cabin isolation shines: low noise and a plush ride on smaller wheels (17-18 inch). Larger alloys on Black Editions firm up the setup, transmitting road imperfections—opt for the softer suspension option.

Optional Dynamic Steering and Drive Select adjust assistance and damping, but base setups suffice for most. Performance models like RS5 thrill with explosive power, yet everyday A5s excel as refined cruisers.

Reliability and Ownership: Built to Last

In surveys like Driver Power 2017, the A5 ranked 35th overall, excelling in build quality, engines, and transmissions. Owners praise durability, with few major issues if serviced properly. Running costs dip for high-power diesels and RS models due to pricier parts.

Common checks: Oil leaks on early TFSIs, DPF clogging in urban-driven TDIs, and suspension wear on high-mileage cars. Timing chains in 2.0 TDI need monitoring post-100k miles.

• Strengths: Robust engines, premium interior longevity.
• Watchpoints: Quattro maintenance, auto gearbox fluid changes.

Interior and Practicality: Luxury Meets Usability

The cabin impresses with soft-touch plastics, supportive seats, and intuitive controls. Visibility aids parking, though rear headroom suffers in coupes. Sportback offers the most space for adults and 825 liters max cargo. Tech includes optional MMI navigation—check functionality on older units.

Buying Advice: Top Picks and Rivals

Best All-Rounder: 2.0 TDI Black Edition—equipped, efficient, grippy.

Economy King: 2.0 TDI Ultra SE, over 55mpg real-world.

Performance Pick: RS5 for thrills, but budget for upkeep.

Avoid early autos without updates and high-mileage V8s. Test Sport suspension for ride preference.

Vs. BMW 4 Series: A5 wins on refinement, loses on driver engagement. Mercedes C-Class Coupe trails in engines but matches luxury.
