The 2025 Audi RS e-tron GT Performance is the most powerful Audi ever built, producing 912 horsepower from its dual electric motors[1]. It rockets from 0-60 mph in just 2.2 seconds according to MotorTrend testing[2]. For internal combustion engines, the 2026 Audi RS Q8 Performance leads with 631 horsepower from its 4.0-liter twin-turbo V8—the most powerful ICE ever in an RS vehicle[3].

US market specifications[1][2][3][4]
The RS e-tron GT Performance represents Audi's peak power achievement. Its 912 horsepower comes from a dual-motor all-wheel-drive setup—the same platform underpinning the Porsche Taycan Turbo S.
The rear motor received the most dramatic upgrade. It now produces 556 horsepower alone—a 107-hp increase over the previous generation while actually weighing 22 pounds less[1]. Combined with the front motor, total system output jumps by a massive 275 horsepower over the outgoing RS e-tron GT[5].
MotorTrend's instrumented testing showed the RS e-tron GT Performance hitting 60 mph in just 2.2 seconds—faster than Audi's claimed 2.4-second time[2]. The quarter-mile falls in 9.9 seconds at 140.2 mph[2]. These numbers make it the quickest production Audi ever built.
The catch? All that power comes with considerable weight. At 5,182 pounds, it's roughly 1,000 pounds heavier than an RS 6 Avant[2]. But the instant torque delivery of electric motors more than compensates on the street.
If you prefer internal combustion, the RS Q8 Performance wears the crown. Its 4.0-liter twin-turbocharged V8 produces 631 horsepower and 627 lb-ft of torque[3].
Audi describes this as "the most powerful internal combustion engine ever featured in an RS vehicle"[3]. The previous RS Q8 made 591 horsepower, so the Performance variant adds 40 hp—not a huge jump, but meaningful at this level.
Real-world testing puts 0-60 times in the mid-3-second range[7]. For a full-size SUV weighing over 5,400 pounds, these numbers border on absurd. The RS Q8 Performance also lapped the Nürburgring in approximately 7 minutes 30 seconds—supercar territory for an SUV[7].
The RS 6 Avant wagon and RS 7 sportback share the same powertrain: a 4.0-liter twin-turbo V8 producing 621 horsepower[4].
Both cars hit 60 mph in 3.3 seconds with electronically-limited top speeds of 174 mph. The main difference? Body style and rear cargo space. The RS 6 Avant gives you wagon practicality with supercar speed—a combination that's become legendary among enthusiasts.
| Model | Engine | Power | 0-60 mph | Top Speed |
|---|---|---|---|---|
| RS 6 Avant | 4.0L TT V8 | 621 hp | 3.3 sec | 174 mph |
| RS 7 | 4.0L TT V8 | 621 hp | 3.3 sec | 174 mph |
Performance figures per TopSpeed testing[4]
For many buyers, the RS 6 Avant represents the sweet spot: more than enough power for any situation, plus the practicality to haul a family and gear. It's the closest thing to a modern-day unicorn.
The Audi R8 V10 Performance produced 602 horsepower from its naturally-aspirated 5.2-liter V10—the last of its kind in Audi's lineup[4]. Audi discontinued the R8 in 2023, making remaining models increasingly collectible.
While lower on paper than the RS e-tron GT, the R8 offered something unique: a mid-engine supercar layout and one of the last great atmospheric V10s in production. It hit 60 mph in 3.2 seconds and topped out at 205 mph[4].
The R8's spiritual successor will likely be an electric hypercar. For now, the RS e-tron GT Performance carries Audi's high-performance banner into the electric era.
Several other RS models deliver serious performance below the 600-hp threshold.
The RS 5 uses a 2.9-liter twin-turbo V6 producing 444 horsepower[4]. It's the entry point to V-powered RS performance, hitting 60 mph in 3.8 seconds.
Both use Audi's iconic 2.5-liter turbocharged inline-five—an engine known for its distinctive sound. The TT RS makes 401 horsepower and reaches 60 mph in 3.6 seconds, while the RS 3 produces 394 horsepower[4].
This five-cylinder remains special because few manufacturers still produce odd-cylinder engines. Audi continues developing it specifically because enthusiasts love the exhaust note.
