Audi’s brand-new PPE platform, which underpins the latest SQ6 e-tron and the Porsche Macan EV, continues to bear fruit. However, this time, the carmaker debuts a new entrant into the sporty sedan segment with the arrival of the 2025 Audi S6 e-tron Sportback and its mass-market twin, the A6 e-tron.
Inspired by the aptly named A6 e-tron concept that debuted in Shanghai in 2021, Audi’s latest will be available in Sportback and Avant forms, but only the sedan will be available in the US market. Still, the production version of this well-received concept captures its sporty but elegant essence while introducing styling elements we’re bound to see in future models. While the e-tron SUV line carries a familiar look, its sedan counterpart strays distinctly and introduces us to a new aesthetic.
Much of the mechanical components that power the Audi S6 e-tron Sportback carry over from the SQ6 e-tron, albeit now housed in a lower and wider machine. This includes its 100 kilowatt-hour (94.4 kWh net) battery pack, 800-volt electric architecture, and rear-biased dual-motor setup. However, the sedan packs even greater performance, producing 496 horsepower or 543-hp for brief periods with launch control engaged. As such, it’ll sprint to 60 mph in 3.7 seconds and continue onto its electronically limited 149-mph top speed. The base rear-wheel-drive A6 e-tron produces 362 hp, while an all-wheel-drive quattro variant bumps up to 422 hp.
Despite housing two electric motors for all-wheel traction, the S6 rides mostly in RWD mode, with the front axle stepping in only when needed for greater efficiency. However, even when both are engaged, the rear unit still develops more power, resulting in a rear-biased configuration. This pairs with an optional air suspension system that cycles between four ride height levels, squatting by nearly an inch at higher speeds.
Thanks to its updated architecture, all variants of this latest e-tron can charge at speeds of up to 270 kilowatts, jumping from 10 to 80 percent in as little as 21 minutes. The big question now, however, surrounds their range as Audi has yet to release official figures for the US market. On the European WLTP cycle, a Euro-spec S6 Sportback e-tron covered over 416 miles on a charge, but given the EPA’s more conservative metrics, expect the US cars to offer figures in the low 300-mile range.
The Audi S6 e-tron Sportback achieves these figures in part due to its ultra-low drag coefficient of just 0.21 Cd. For context, even the R8 could only manage 0.34 Cd with its rear spoiler retracted, making the S6 not just slippery by EV standards but the most aerodynamic road-going Audi ever. Cleverly positioned air curtains, an optimized undertray, and a downsized greenhouse characterized by its sloping roof are some of the elements that help achieve this.
On the styling front, the Audi S6 e-tron Sportback incorporates ultra-slim daytime running lights paired with extensive gloss black trim that hides its main headlights, the sensors for its driver assistance features, and its lower intakes. This allows its body-colored inverted grille and contrasting accent color to be the main focal point. In S6 form, this accent color adorns sizable side intakes that help channel air into and through the front wheel wells.
Along its sides, the Audi S6 e-tron Sportback has a sleek, sloping roofline emphasizing its low ride height and a tall side sill that doubles as an indicator of where its battery pack sits. The S6 receives a standard set of 20-inch wheels; however, the model photographed above wears an optional set of 21s, one of nine available designs for the A6 e-tron lineup.
However, the rear houses the most significant updates, as its roof slopes neatly into a sizable rear hatch. Audi’s signature light bar is even more extensive than ever, topped by an illuminated four-ring logo. The gloss black and accent color touches carry over from the front onto the diffuser, which extends well into the rear bumper while sporting four thin fins.
Like its SUV counterpart, the S6’s head and tail lights can display patterns or project messages onto other drivers to increase safety on the road. The system allows drivers to select a preferred lighting signature and displays vital features such as proximity warnings. However, due to US regulations, these car-to-car features and active digital light signatures will be restricted to European models only.
Inside, the Audi S6 e-tron Sportback sports a screen-heavy layout that is quickly becoming familiar among the brand’s latest models. Moving left to right, it begins with an 11.9-inch digital instrument cluster housed in the same gloss black bezel as a 14.5-inch central infotainment screen. Just beside them, though, is a new 10.9-inch passenger display, which creates a nearly fully digital dashboard from A-pillar to A-pillar. Adding another layer of information is an updated augmented reality heads-up display.
In contrast, the rest of the S6’s interior is strikingly minimalist. Its three-spoke steering wheel, for example, houses just a few haptic feedback buttons, while its center console houses just its gear selector and a handful of other buttons. In typical Audi fashion, its front seats feature perforated leather, although a vegan interior adorned by a diamond-stitched pattern is also available. Subtle suede touches on its center console and door cards add more textures to the mix to create a subtle but elegant cabin layout.
While the Audi S6 e-tron Sportback goes on sale across the pond in September of this year, it and its A6 counterparts won’t hit US shores until early 2025. As expected, Audi has yet to release official pricing figures for its new sporty sedan. However, in Europe, it’ll carry a starting price of €99,500 or $107,600 using current conversion rates.
