The 2026 Audi S6 e-tron delivers 543 horsepower with launch control, sprints to 60 mph in 3.9 seconds, and charges from 10-80% in just 21 minutes[1]. Starting at $78,700, this all-electric performance sedan sits between the standard A6 e-tron and Audi’s track-focused e-tron GT, offering a compelling balance of daily usability and genuine sports car acceleration[2].
Quick Verdict
The S6 e-tron is Audi’s answer to the BMW i5 M60—and it delivers. Built on the Premium Platform Electric (PPE) architecture with 800-volt technology, it charges faster than most competitors and offers up to 324 miles of EPA-estimated range[1]. Car and Driver notes it’s “a hotter version of the A6 e-tron sedan, but not as sporty as the S-badged gas-engine cars in the company’s stable”[3].
That assessment captures the S6 e-tron’s personality perfectly. It’s fast—genuinely fast—but prioritizes refinement over raw aggression. If you want the EV equivalent of a traditional Audi S sedan, this delivers.
2026 Audi S6 e-tron Pricing
| Trim | MSRP | Key Features |
|---|---|---|
| Premium | $78,700 | 543 hp (launch control), dual motors, quattro AWD, sport adaptive air suspension, 21″ wheels[2] |
| Premium Plus | $82,200 | Adds LED headlights with digital DRLs, interior ambient lighting, Bang & Olufsen audio[2] |
| Prestige | $84,600 | Adds digital OLED taillights, eight light signatures, head-up display, ventilated massage seats[2] |
All prices exclude the $1,295 destination fee. For context, the base A6 e-tron starts at $65,900, making the S6’s $12,800 premium significant—though you get 168 more horsepower[2].
Some dealers are currently offering $7,500 in specials, bringing real-world transaction prices below $80,000 for the Premium Plus trim[4]. For buyers researching what MSRP actually means, these incentives can substantially reduce out-the-door cost.
Performance and Powertrain
The S6 e-tron uses dual electric motors—an induction AC motor on the front axle producing 188 hp and a permanent-magnet synchronous motor on the rear producing 375 hp[3]. Combined output reaches 496 hp in normal driving, jumping to 543 hp when launch control activates[1].
| Specification | S6 e-tron |
|---|---|
| Total System Power | 496 hp (543 hp w/launch control)[1] |
| Torque | 428 lb-ft (rear motor)[3] |
| 0-60 mph | 3.9 seconds (estimated)[1] |
| Top Speed | 149 mph[5] |
| Drivetrain | Quattro AWD with rear torque bias[5] |
Audi programmed the S6 e-tron with a rear-wheel-drive torque bias, enhancing driving dynamics and creating a more engaging experience than typical all-wheel-drive EVs[5]. The system varies torque distribution constantly, sending power where it’s needed most.
First-drive reviews from MotorTrend describe the acceleration as “precise and easy to modulate”—you’re never wanting for more power when merging or passing[6]. And the S6 feels planted through corners, with minimal body roll despite its weight.
Driving Dynamics
Sport adaptive air suspension comes standard on all S6 e-tron trims—it’s optional on the regular A6 e-tron[5]. The suspension offers four height settings and multiple damping modes, letting you dial in comfort for highway cruising or firmness for spirited driving.
The Audi Club of North America praised the S6’s balance: “It strikes a superb balance between luxury and performance, proving that Audi’s performance EVs can still deliver thrills without compromise”[7]. Body roll is minimal during turn-in, and the S6 feels noticeably more planted than the standard A6 quattro.
The catch? Regenerative braking maxes out at 220 kW, with user-selectable modes ranging from coast-free driving to near one-pedal operation[1]. Some drivers find the transition between regen and friction braking slightly less refined than competitors. Your mileage may vary depending on driving style.
For those exploring Audi’s electric vehicle lineup, the S6 e-tron sits between the Q8 e-tron SUV and the e-tron GT in terms of performance positioning.
Battery and Charging
| Specification | S6 e-tron |
|---|---|
| Battery Capacity | 100 kWh gross (94.9 kWh usable)[1] |
| Architecture | 800-volt[1] |
| Peak DC Fast Charging | 270 kW[3] |
| 10-80% Charge Time | 21 minutes[2] |
| AC Charging (Level 2) | 9.6 kW (US)[1] |
The 800-volt architecture is the S6 e-tron’s secret weapon. While most EVs use 400-volt systems, the S6’s higher voltage enables faster charging—270 kW peak versus the typical 150-200 kW[1]. Real-world testing shows 10-80% charges completing in approximately 21 minutes at compatible stations[8].
When connected to older 400-volt DC chargers, the battery splits into two banks charging simultaneously at up to 135 kW[1]. This backward compatibility means you won’t be stranded if 800V infrastructure isn’t available.
For long-distance travel, EVKX estimates the S6 e-tron can complete a 1,000 km (621 miles) challenge at highway speeds with just two charging stops totaling 40 minutes[8]. That’s genuine road-trip capability.
Audi owners get access to Electrify America’s network, and the S6 e-tron can also charge at Tesla Superchargers with an adapter.
Range Estimates
| Model | EPA Range |
|---|---|
| S6 Sportback e-tron | 324 miles[2] |
| A6 e-tron Performance (RWD) | 392 miles[2] |
| A6 e-tron quattro | 377 miles[2] |
The S6 e-tron’s 324-mile EPA range trails the base A6 e-tron by 68 miles—the price of that extra motor and performance tuning[2]. Real-world cold-weather testing from Top Gear showed both the Audi A6 e-tron and BMW i5 dropping to around 250 miles in cold conditions[9].
That said, the fast charging capability partially offsets the range penalty. You’ll stop more often but spend less time charging than competitors with slower DC fast charging speeds.
Interior and Technology
The S6 e-tron shares its cabin with the A6 e-tron, adding sport-specific touches like S badging and unique seat designs. J.D. Power described the interior as “whisper-quiet and smooth, making this an ideal high-speed vehicle for covering long distances”[10].
Standard features across all S6 e-tron trims include:
- MMI touch response infotainment with haptic feedback
- Audi virtual cockpit plus (configurable digital instrument cluster)
- Wireless Apple CarPlay and Android Auto
- Four-zone automatic climate control
- Sport seats with leather/microfiber upholstery
- Panoramic glass roof
The Prestige trim adds digital OLED taillights—a first for the A6/S6 lineup—that can display eight different light signatures[2]. Head-up display, ventilated massage seats, and additional driver assistance features round out the top trim.
Audi doesn’t charge extra for Apple CarPlay—wireless smartphone integration comes standard on all trims.
