Cost to keep
What it costs to own, by how long you keep it
Scheduled servicing only, from a brand-new A6 e-tron at 12,000 miles a year. Insurance, fuel, tires and depreciation are yours to add - this is the part the shop charges you for.
| You keep it | Odometer | Servicing | Per month |
|---|---|---|---|
| 1 year | 12,000 mi | $90 | $8 |
| 3 years | 36,000 mi | $615 | $17 |
| 5 years | 60,000 mi | $1,330 | $22 |
| 7 years | 84,000 mi | $1,670 | $20 |
| 10 years | 120,000 mi | $2,660 | $22 |
| 15 years | 180,000 mi | $3,990 | $22 |
Per-month can dip as the horizon lengthens - a major service lands in one year and then averages out across all the months after it. The left column is what you actually spend.
Beyond the schedule, the first big-ticket item this A6 e-tron is known for is Adaptive air suspension (if equipped) from about 80,000 miles ($1,500-$3,000). It is a range, not a certainty - but it is the number to have in your head at the dealership.
Operator notes
New PPE-platform EV (800V) for 2026, Sportback and Avant. EV = NO oil changes; scheduled work is tires, cabin filter, brake fluid (2-yr) and long-interval battery coolant. Regen braking greatly extends pad/rotor life. Heavy = fast tire wear. 8yr/100k battery warranty.
When the smart money sells
Keeping it yourself, there is no cutoff - the table above runs to fifteen years. On fleet math, where a car has to keep earning, a battery-electric A6 e-tron retires around 150,000 miles - but the exit window opens earlier here: Adaptive air suspension (if equipped) risk window ($1,500-$3,000) opens ~80,000 mi. Carlyle's garage tracks this per car, against your actual odometer.
Cost ranges are typical US independent-shop estimates and vary by region and condition. Modeling, not mechanic advice - always confirm against your car's service records.
