Audi A8 Limousine TFSI e

The Audi A8 TFSI e and A8 L TFSI e are flagship plug-in hybrid luxury saloons sharing identical charging hardware. Both are badged 60 TFSI e quattro and combine a 3.0-litre turbocharged V6 petrol engine with an electric motor for a combined output of 340 kW (462 PS) and 700 Nm of torque. The A8 L carries a longer wheelbase for extended rear passenger space, but the powertrain, battery, and charging spec are unchanged. The battery is 17.9 kWh gross and 14.4 kWh usable, with a 7.4 kW two-phase onboard AC charger. No DC rapid charging is available on either variant. The Type 2 charging port is located on the left rear flank, and both cars cover 0–100 km/h in 4.9 seconds with a WLTP electric range of up to 58 km (36 miles).

Battery, range, and powertrain

The lithium-ion battery sits beneath the luggage compartment floor and provides 14.4 kWh of usable capacity, enough for up to 58 km of electric-only running on the WLTP cycle. The electric motor is integrated into the eight-speed tiptronic gearbox housing, keeping quattro all-wheel drive active at all times. The A8 and A8 L are available in a single power configuration: 340 kW combined, with a top speed of 250 km/h (155 mph) and electric-only operation possible up to 135 km/h (84 mph).

Charging at home and at public wallboxes

The A8's 7.4 kW onboard charger operates across two phases at 16A per phase. On a three-phase wallbox or public AC post, both phases are available and the car charges at the full 7.4 kW, completing a full charge from empty in approximately two and a half hours. On a standard single-phase home wallbox, the car can only access one of its two phases, capping the charge at 16A × 230V = 3.7 kW. At that rate a full charge takes around four hours. To reach the full 7.4 kW at home, a three-phase wallbox installation is required. Most owners keep the A8 TFSI e topped up overnight, starting each day with a full battery and relying on the petrol engine only for longer runs.

Which cable do you need

The 7.4 kW two-phase onboard charger draws 16A across two phases, which aligns correctly with an 11 kW Voldt® Type 2 cable, rated at 16A per phase. This covers every public AC charging point and home wallbox across Europe without restriction. For those planning ahead for a future vehicle with 22 kW three-phase charging, a 22 kW cable is the logical upgrade: fully compatible with the A8 today and requiring no change of hardware when moving on.

Cable length

The charging port on both the A8 and A8 L sits on the left rear flank, so reversing to the wallbox is generally the most practical approach at home. For most driveways and garages a 6-metre cable is the comfortable everyday choice. An 8-metre cable gives additional reach for public charging bays where the post may not be directly beside the parking space. For longer runs to a charge point or for fleet and commercial settings, Voldt® also supplies cables in 10 and 15-metre lengths, and for specialist installations such as underground car parks or custom-built charging areas, cables are available up to 40 metres.

Portable charging with a CEE charger

The Voldt® portable CEE charging cable is a practical companion for both the A8 and A8 L on longer trips or wherever a fixed wallbox is not available. On a 16A single-phase CEE socket (3.7 kW), only one phase is available and the car charges at 3.7 kW, completing a full charge in approximately four hours. On a 16A three-phase CEE socket, the car draws from two of the three available phases at 16A each, delivering the full 7.4 kW and a charge time of approximately two and a half hours. The same applies on a 32A three-phase CEE socket: the car takes 16A per phase from two phases, charging at 7.4 kW and completing in approximately two and a half hours.

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 and result in the four-hour charge time noted above. For a 14.4 kWh battery, a campsite overnight stop is entirely practical at this rate. On a standard domestic socket at 2.3 kW, a full charge takes around seven hours, making an overnight plug-in at home a straightforward option when no wallbox is available.
