Practical Notes: Q4 e-tron on IONNA

The Q4 e-tron's CCS port plugs directly into IONNA's CCS stalls without an adapter. Check the IONNA app before your first session to confirm which connector your target station uses — mixed-connector deployments are common in 2026.

On a session-by-session basis, the Q4 e-tron's 170 kW peak charging speed is well-matched to IONNA's DC fast hardware. Expect a 10→80% charge in roughly 16 min. Real-world times run 10–20% longer due to charging taper and battery preconditioning.

Cost-wise, one $20.99 full charge on IONNA represents $0.07 per mile of driving — about 7.3¢/mile. A gas equivalent at 30 mpg and $3.50/gal is roughly 11.7¢/mile, so this charging session is still cheaper than gas. Over 15,000 miles/year, exclusive reliance on IONNA would cost roughly $1,366.67/year in fuel — a meaningful delta compared to mostly-home charging (~$704.69/year).

For most Q4 e-tron owners, the realistic use-pattern for IONNA is road trips and occasional top-ups — not primary fueling. If you live in an apartment or condo and rely on public charging as your main option, factor in the per-session pricing with no membership option. For regular home charging in a specific state, check our home vs public analysis and your Q4 e-tron state-by-state breakdown.
