Dimensions of the 2015 Audi A4: How Big Is It?

The 2015 Audi A4 is a compact executive sedan measuring roughly 4.70 m long, 1.83 m wide (about 2.04 m including mirrors), and 1.43 m tall, with a wheelbase of about 2.81 m and a boot capacity of around 480 liters. These figures place it squarely in the premium compact segment, offering a balance between city-friendly size and comfortable interior space.

Overview of the 2015 Audi A4

The 2015 Audi A4 represents the final model year of the B8 generation (including the facelifted “B8.5”), and its dimensions were largely standardized across most markets. While equipment, engines, and some body styles vary by region, the core sedan’s size remains consistent enough to give buyers a clear sense of its footprint on the road and in parking spaces.

Main Exterior Dimensions

Understanding the basic exterior dimensions is essential for evaluating how the 2015 Audi A4 will fit in a garage, parking space, or tight urban streets, as well as how it compares to rivals like the BMW 3 Series and Mercedes-Benz C-Class.

• Overall length: approx. 4,701 mm (185.0 in)
• Overall width (body only): approx. 1,826 mm (71.9 in)
• Overall width (including mirrors): approx. 2,040 mm (80.3 in)
• Overall height: approx. 1,427 mm (56.2 in)
• Wheelbase: approx. 2,808 mm (110.5 in)
• Front track: approx. 1,564–1,573 mm (61.6–61.9 in), depending on wheel/tire setup
• Rear track: approx. 1,551–1,557 mm (61.1–61.3 in), depending on wheel/tire setup

Taken together, these figures confirm the 2015 A4’s status as a compact executive sedan: long enough to offer a stable highway ride and a usable back seat, but still narrow and short enough to remain manageable in everyday traffic and typical parking spaces.

Interior Space and Practicality

Dimensions inside the cabin determine daily comfort, particularly for taller drivers and passengers, as well as how practical the car is for family use or commuting with luggage and equipment.

Cabin Space

While Audi does not always publish every interior measurement in all markets, independent measurements and manufacturer data give a good picture of the space available in the 2015 A4 sedan.

• Seating capacity: 5 occupants
• Front headroom: approx. 1,000 mm (39–40 in), slightly less with sunroof
• Rear headroom: approx. 950–960 mm (about 37–38 in)
• Front legroom: generous for most drivers in the compact luxury class
• Rear legroom: adequate for adults on shorter trips, comfortable for children and moderate-height passengers

Overall, the interior dimensions of the 2015 A4 favor front occupants, as is typical in this class, while still offering usable space in the rear for two adults or three passengers on shorter journeys.

Cargo Capacity

The trunk size is a vital dimension for anyone planning to use the 2015 Audi A4 for commuting, airport runs, or longer trips with luggage.

• Boot (trunk) capacity, sedan: approx. 480 liters (about 17.0 cu ft)
• Rear seats: split-folding (in most trims/markets), expanding usable cargo length
• Opening: relatively wide sedan opening, though not as tall as a hatchback or Avant (wagon)

This luggage space is competitive within the compact luxury segment, allowing the A4 to carry several suitcases or a mix of bags and bulky items, especially when the rear seats are folded down.

Body Style Variations

The 2015 Audi A4 lineup in many markets also included the Avant (wagon) and performance-oriented S4 versions, all of which share a similar footprint but differ slightly in height and cargo capacity.

• A4 Avant (wagon): similar length and width to the sedan, slightly different rear overhang and a larger cargo area.
• S4 sedan: broadly the same exterior dimensions as the standard A4 sedan, with minor variations due to suspension setup and wheel/tire combinations.
• Ground clearance: typically modest, with S-line or S4 variants sitting slightly lower than standard A4 models.

These variations do not fundamentally change how much space the car occupies on the road, but they may influence practical aspects like loading height, trunk shape, and underbody clearance.

How the 2015 Audi A4 Compares in Its Class

Dimensions alone tell only part of the story; many buyers are interested in how the 2015 A4 stacks up against similarly sized competitors from other premium brands.

• Versus BMW 3 Series (F30): comparable length and width, with very similar wheelbase; interior and trunk space are closely matched.
• Versus Mercedes-Benz C-Class (W205): again, very similar footprint, with small differences in length and width that are rarely noticeable in everyday use.
• Versus mainstream midsize sedans: slightly shorter and often narrower than some non-premium midsize sedans, but with comparable interior room thanks to efficient packaging.

In practical terms, the 2015 Audi A4’s size is fully in line with its direct rivals, offering no major advantages or disadvantages in raw dimensions, but competing strongly on refinement and perceived quality.

Why These Dimensions Matter for Buyers

For anyone considering a used 2015 Audi A4, knowing the car’s size is important not only for comfort but also for day-to-day practicality, parking, and running costs.

• Parking and urban driving: its compact executive size makes it easier to maneuver than a full-size sedan, yet more spacious inside than many smaller compacts.
• Garage fit: with a length just under 4.8 m, it typically fits standard single garages, though measuring available space is always wise.
• Family use: adequate rear space and a 480-liter trunk make it viable as a family car for many households, especially in urban or suburban settings.

These considerations help prospective owners judge whether the 2015 A4 fits their lifestyle, from tight city parking to weekend trips with family and luggage.

Summary

The 2015 Audi A4 is a compact executive sedan with an overall length of about 4,701 mm, width of around 1,826 mm (about 2,040 mm including mirrors), height of roughly 1,427 mm, and a wheelbase close to 2,808 mm. Inside, it offers seating for five, reasonable rear passenger space, and a competitive 480-liter trunk. In size and proportions, it aligns closely with key rivals such as the BMW 3 Series and Mercedes-Benz C-Class, delivering a balance between urban usability and long-distance comfort that has defined this generation of the A4.

What year Audi A4 to stay away from?

You should be cautious with Audi A4 years 2009-2012 (2.0 TFSI) due to excessive oil consumption, and 2005-2014 (Multitronic CVT) due to potential transmission issues. Other years to approach with caution include models with the early B9 diesels (2016-2018) which can have problems with the AdBlue system. Also, be aware of issues like oil consumption, carbon buildup, and electrical problems in other 2.0T engines and direct-injection engines in general, particularly before the 2014 model year.
 
Years and specific issues to avoid

• 2009–2012 (2.0 TFSI petrol models): High risk of excessive oil consumption, often requiring engine rebuilds or updated parts.
• 2005–2014 (B7/B8 with Multitronic CVT gearbox): Prone to juddering and failures, especially if transmission fluid was not changed on schedule.
• 2016–2018 (early B9 diesel models): Reports of problems with the AdBlue tank and heater, and NOx sensors, which can cause limp mode.

Other years and engines to be cautious about

• Models with 2.0L turbocharged four-cylinder engines (especially pre-2014): Can experience excessive oil consumption, timing chain issues, oil leaks, and carbon buildup. 
• 2006–2017 models (with 2.0FSI, 2.0TFSI, and 3.2FSI engines): Direct-injection engines are susceptible to carbon buildup, which can decrease power and fuel economy. 
• 1997–2007, 2009, and 2011 models: Some may experience engine misfires, which can lead to engines stalling after idling. 

What to look for when buying

• Service history: A complete service history is crucial, particularly for the Multitronic transmission fluid changes and oil consumption issues. 
• Professional inspection: Have a qualified mechanic thoroughly inspect any pre-2014 A4 with a 2.0T engine. 
• Maintenance: Even for models without known major issues, be prepared for potentially higher maintenance costs compared to non-luxury brands, as these vehicles may require premium fuel and specific, high-quality fluids.
