Audi A6 Avant TFSI charging cable

The Audi A6 TFSI e and A6 Avant TFSI e are executive plug-in hybrid saloon and estate variants built on the same platform and sharing identical charging hardware. The A6 is the saloon; the A6 Avant is the estate. A significantly updated generation arrived in 2025 under the new e-hybrid quattro designation, bringing a larger battery, a faster onboard charger, and a meaningfully longer electric range. Both generations and both body styles are covered here. The previous-generation A6 TFSI e Saloon has its Type 2 port on the left front flank; the previous-generation A6 Avant TFSI e has its port on the left rear quarter. On the new 2025 e-hybrid, both the Saloon and Avant carry the port on the left rear quarter.

Previous generation: A6 TFSI e Saloon and Avant (until 2025)

The outgoing A6 TFSI e pairs a 2.0-litre TFSI petrol engine with an electric motor for a combined output of 220 kW (299 PS) and 450 Nm. Battery is 17.9 kWh gross with 14.4 kWh usable, giving a WLTP electric range of up to 69 km (43 miles) for the Saloon and up to 66 km (41 miles) for the Avant. The onboard AC charger is 7.4 kW single-phase. There is no DC rapid charging. A full charge from empty takes approximately two and a half hours at a compatible wallbox. The 0–100 km/h time is 6.3 seconds for both body styles.

New generation: A6 e-hybrid Saloon and Avant (2025 onwards)

The 2025 A6 e-hybrid retains the same 2.0-litre TFSI engine and electric motor combination but with a substantially upgraded battery: 25.9 kWh gross and 20.7 kWh usable, a 45% increase over the previous model. Combined system output is 220 kW (299 PS) with 450 Nm of torque and 0–100 km/h in 6.0 seconds. WLTP electric range rises to up to 103 km (64 miles) for the Saloon and up to 101 km (63 miles) for the Avant. The onboard AC charger steps up to 11 kW three-phase, with a full charge from empty taking approximately two and a half hours at a compatible three-phase wallbox. There is no DC rapid charging on this model.

Choosing the right cable

For the previous-generation A6 TFSI e, the 7.4 kW single-phase onboard charger requires 32A on a single line to reach its full rate. An 11 kW three-phase cable is not the correct match: its conductors are rated at 16A per phase, and on a single-phase supply it delivers only 16A × 230V = 3.7 kW, halving the charge rate. The correct choice is a Voldt® 7.4 kW single-phase cable or a 22 kW three-phase cable, whose 32A-per-phase conductors carry the full single-phase load without restriction.

For the new 2025 A6 e-hybrid, the 11 kW three-phase onboard charger makes an 11 kW Voldt® Type 2 cable the correct match at any three-phase wallbox or public AC post. On a single-phase home wallbox, the same bottleneck applies as on the previous generation: an 11 kW cable restricts output to 3.7 kW, so a 7.4 kW or 22 kW cable is needed to reach the wallbox's full 7.4 kW rate.

Across both generations, a 22 kW cable is the most versatile choice: it handles 32A on a single line, delivers 11 kW at any three-phase public post, and future-proofs the purchase for any vehicle with higher AC charging capacity.

Cable length

Port location varies by generation and body style, so it is worth checking before settling on a length. The previous-generation Saloon has its port on the left front flank, making nose-in parking to the wallbox the natural approach. The previous-generation Avant and both variants of the new 2025 e-hybrid have their ports on the left rear quarter, so reversing to the wallbox works best in most home setups. For everyday home use, a 6-metre cable covers the vast majority of configurations comfortably. For public charging, where bay layouts and post positions vary widely, an 8-metre cable provides reliable reach across most stations. For longer runs to a charge point or dedicated installations, 10, 15, and up to 40-metre options are available.

Portable charging with a CEE charger

The Voldt® portable CEE charging cable extends charging options to any location with an industrial socket.

For the outgoing A6 TFSI e (7.4 kW single-phase ceiling): on a 16A single-phase CEE socket (3.7 kW), a full charge takes around four hours. On a 16A three-phase CEE socket, the single-phase charger draws from one phase only, again receiving 3.7 kW and taking around four hours. On a 32A three-phase CEE socket, one phase carries 32A at 230V = 7.4 kW, completing a full charge in approximately two and a half hours. On a standard domestic socket at 2.3 kW, a full charge takes around six and a half hours, a practical overnight option for this battery size.

For the new 2025 e-hybrid (11 kW three-phase ceiling): on a 16A three-phase CEE socket (11 kW), a full charge takes approximately two and a half hours. On a 32A three-phase CEE socket (22 kW available), the car is capped at 11 kW and the result is the same. On a 16A single-phase CEE socket (3.7 kW), a full charge takes around five and a half hours. On a standard domestic socket at 2.3 kW, a full charge takes around ten hours, making an overnight plug-in a practical option for this battery size.

Red three-phase CEE sockets are found at industrial sites, workshops, and some commercial marinas. Standard European campsite hookup points use blue single-phase 16A CEE sockets, which cap output at 3.7 kW: around four hours for the outgoing model and five and a half hours for the new e-hybrid.
