The current Audi RS 3 is 178.3″ long, 72.8″ wide, on a 103.5″ wheelbase, weighing 3,616 lb. Since 2017 it has grown 1% in length and gained 0% in weight. At 14.9 feet it fits a standard garage and fits a street parking space.
Every Audi RS 3 generation, measured
One row per generation. Watch the weight column — that is where most of the change happens, and it is the number that decides fuel use, tyre wear and how far the car takes to stop.
| Generation | Length | Width | Height | Wheelbase | Curb weight |
|---|---|---|---|---|---|
| 2017–2021 | 176.4″ | 70.9″ | 55.1″ | 103.5″ | — |
| 2025–2026 | 178.3″ | 72.8″ | 55.5″ | 103.5″ | 3,616 lb |
From 2017 to today the RS 3 gained 2″ of length (1%) and 0 lb of weight (0%). A modern compact often outweighs the mid-size car of a generation before.
RS 3 year by year
Measured every model year, not just at generation changes — 7 years on record. Small moves inside a generation are facelifts; the jumps are new platforms.
| Model year | Length | Width | Wheelbase | Curb weight | Body styles |
|---|---|---|---|---|---|
| 2026 | 178.3″ | 72.8″ | 103.5″ | 1 | |
| 2025 | 178.3″ | 72.8″ | 103.5″ | 1 | |
| 2021 | 176.4″ | 70.9″ | 103.5″ | 1 | |
| 2020 | 176.4″ | 70.9″ | 103.5″ | 1 | |
| 2019 | 176.4″ | 70.9″ | 103.5″ | 1 | |
| 2018 | 176.4″ | 70.9″ | 103.5″ | 1 | |
| 2017 | 176.4″ | 70.9″ | 103.5″ | 1 |
Will a RS 3 fit
The practical question behind every dimensions search. A single-car garage in the US is typically 20 feet deep; a street parking space is about 18. We allow a foot of clearance in both — nobody parks to the millimetre.
| Space | Typical size | This car | Verdict |
|---|---|---|---|
| Single garage | 20 ft deep | 14.9 ft | Fits, with room to open the door |
| Street parking space | 18 ft | 14.9 ft | Fits comfortably |
| Standard parking bay width | 8.5 ft wide | 6.1 ft | Room to open doors both sides |
Against cars of the same length
Compared with 922 vehicles within ten inches of the same length — a fair proxy for «cars of this size», regardless of what the marketing calls them.
| Measure | This car | Typical car of this length | Difference |
|---|---|---|---|
| Width | 72.8″ | 70.9″ | +1.9″ |
| Wheelbase | 103.5″ | 104.7″ | -1.2″ |
| Curb weight | 3,616 lb | 3,351 lb | 265 lb |
A longer wheelbase for the same overall length means shorter overhangs — usually more cabin space and a steadier ride. Lighter than typical for its size generally means better fuel economy and shorter stopping distances.

How we measure
Dimensions come from NHTSA vPIC and Transport Canada vehicle records — manufacturer-declared figures, held in metric and converted to inches and pounds for display.
One row per generation, not per model year: manufacturers rarely change the body between facelifts, and a table of forty near-identical rows helps nobody. Where a generation offered several body styles, the figures are the base measurements for that generation.
