Audi E-Tron RS charging cable

The RS e-tron GT has run across two distinct generations, both sharing the same four-door Gran Turismo body and 800-volt electrical architecture, but differing substantially in power output, battery capacity, and charging speed. The original generation, on sale from 2021 to early 2024, used a 93.4 kWh gross battery with 85 kWh usable, producing 475 kW (637 PS) and 830 Nm through quattro all-wheel drive. WLTP range was rated at up to 294 miles and DC rapid charging peaked at 270 kW. The updated generation, launched in 2024, brought a revised 105 kWh gross battery with 97 kWh usable, and split the RS nameplate into two variants. The RS e-tron GT produces 630 kW (845 PS) in overboost, covers 0–62 mph in 2.8 seconds, and is rated at up to 365 miles WLTP. Above it sits the RS e-tron GT performance, producing 680 kW (925 PS) with a push-to-pass function delivering a 10-second burst of an additional 70 kW, reaching 62 mph in 2.5 seconds with a WLTP range of up to 364 miles. DC charging on the updated car peaks at 320 kW. All variants are full BEVs with no combustion engine. Like other PPE and J1-platform Audi EVs, the RS e-tron GT carries charging ports on both sides of the car. The combined CCS2/Type 2 inlet sits on the right front flank: in right-hand-drive UK configuration this is the offside, and it handles both DC rapid charging and AC. A second Type 2-only inlet on the left front flank handles AC charging and gives flexibility when the port side would otherwise face away from a charge post.

AC charging and wallbox times

The onboard AC charger is 11 kW three-phase as standard on both generations, with a 22 kW option available. At 11 kW on a compatible wallbox, the 85 kWh battery in the original RS e-tron GT takes approximately nine hours and fifteen minutes from near-empty. The 97 kWh battery in the updated car extends that to around ten and a half to eleven hours at 11 kW, which Audi describes as filling an empty battery overnight. With the optional 22 kW charger, both batteries charge in roughly five to six hours from a three-phase supply.

At a standard household socket supplying 2.3 kW, the 85 kWh battery would take around 37 hours to fill and the 97 kWh battery around 42 hours: a domestic socket is strictly a fallback here, not a viable regular charging method on a battery of this size.

The 11 kW standard charger draws three-phase power, so a three-phase wallbox is necessary to reach the full 11 kW rate. A single-phase 7.4 kW supply limits the charge to 7.4 kW, adding around five hours to a full charge on the 97 kWh battery compared to 11 kW three-phase.

What cable the RS e-tron GT needs

Both Type 2 inlets accept a standard Voldt® Type 2 charging cable, covering home wallboxes and public AC charge points across both generations. The standard onboard charger is 11 kW three-phase, and an 11 kW Voldt® cable is the correct match for both the original and updated car. Specifying a 7.4 kW cable limits the charge rate and adds unnecessary time to every session: with a 97 kWh battery, the difference between 7.4 kW and 11 kW amounts to approximately four extra hours on a full charge. For cars specified with the optional 22 kW charger, a 22 kW Voldt® cable completes the setup, provided the wallbox also delivers 22 kW three-phase.

The combined DC/AC port sits on the right front flank, which in UK bay layouts is the offside and typically faces away from the charge post in a parallel bay. The AC-only port on the left covers most home driveway and parallel bay situations in the UK directly. A 6-metre cable handles the majority of home charging setups without difficulty. An 8-metre cable is the more practical choice for the combined port on the right, where the car may need to nose deeper into a bay to bring that side within reach of a post, or for public locations where the post sits further back than expected.

Portable charging

The Voldt® portable CEE charging cable gives access to industrial sockets where a wallbox is not available. A 32A three-phase CEE socket delivers 22 kW, reducing to 11 kW in practice on the standard onboard charger, with charge times matching those of a home wallbox. A 16A three-phase CEE socket delivers 11 kW, the same ceiling as the standard charger. A 16A single-phase CEE socket supplies 3.7 kW, which takes around 23 hours to fill the 85 kWh battery and around 26 hours for the 97 kWh: workable for extended overnight stops at a campsite or marina, but slow enough that three-phase CEE access is worth seeking out when the car needs a meaningful top-up.

The Schuko cable at 2.3 kW from a household socket is a last resort on a battery this size. It adds around 23 kWh over a ten-hour window, equivalent to roughly 65–80 miles of additional range depending on driving conditions, which may be enough to reach the next wallbox or rapid charger the following day, but no more than that.
