The 2026 Audi RS Q8 Performance is a beast that redefines what an SUV can do. As Audi’s most powerful internal combustion vehicle ever, it’s a family hauler that can drop the kids at school, impress clients at lunch, and dominate hot laps at the track—all in a single day. Priced at AUD $255,800 in Australia, it’s a premium proposition, but with a 471kW twin-turbo V8, carbon-ceramic brakes, and a Nürburgring SUV lap record of 7:36.698, it’s a compelling package.
As an automotive reviewer with 8 years of experience testing performance cars across Sydney’s roads and tracks, I’ve driven the RS Q8 Performance (thanks to CarsGuide’s first drive) to see if it lives up to the hype. Spoiler: it’s a lot of everything—power, luxury, and price.
Let’s dive into what makes this super SUV tick for Aussie buyers in 2025.
Unrivaled Power: The Heart of the Beast
Under the bonnet lies a 4.0-litre twin-turbo V8 with 48V mild-hybrid assistance, delivering 471kW (640hp) and 850Nm of torque—30kW and 50Nm more than the standard RS Q8. This makes it Audi’s most potent production petrol engine, surpassing even the R8 supercar. Paired with an 8-speed Tiptronic automatic and quattro all-wheel drive, it rockets from 0–100km/h in a claimed 3.6 seconds (tested at 4.4 seconds against a strong headwind at Lakeside Raceway). The top speed is electronically capped at 250km/h, with an optional 305km/h limit.
My Experience: Flooring it on a Sydney test track felt like unleashing a supercar trapped in an SUV’s body—violent yet controlled. The RS sports exhaust, lighter by 5kg due to reduced sound deadening, delivers a sinister V8 growl that echoes through the cabin.
Ownership Tip: Expect fuel consumption to be significantly higher than the claimed 12.2L/100km during spirited drives; premium unleaded fuel is recommended.
Track-Ready Dynamics with Everyday Comfort
The RS Q8 Performance isn’t just about raw power—it’s engineered to handle like a hot hatch despite its 2,350kg mass. Adaptive air suspension with up to 90mm ride height variation, active roll stabilization, all-wheel steering, and a quattro sport differential work together to defy its size.
At speeds above 80km/h, rear wheels steer with the fronts for sharper cornering, while below 80km/h, they counter-steer for tighter turns. The result? A big SUV that feels nimble, with no body roll or understeer, as proven on Spain’s Parcmotor Castelloli track. It set a Nürburgring SUV record, beating the Porsche Cayenne Turbo GT by over two seconds.
My Experience: On Sydney’s twisty coastal roads, the RS Q8 Performance cornered with precision, soaking up bumps despite its massive 23-inch forged alloy wheels (5kg lighter per corner than the previous 22-inchers). The ride is firm yet comfortable, ideal for long drives.
Ownership Tip: Use Comfort mode for daily commutes to soften the suspension; Dynamic mode is for track days or spirited backroads.
Design: Subtle Yet Menacing
The 2026 RS Q8 Performance gets a facelift with a honeycomb Singleframe grille, larger air intakes, and HD Matrix LED headlights with customizable signatures. The rear features OLED tail-lights with a proximity indication feature and a gloss-black diffuser with carbon-fibre surrounds (optional Carbon Package).
New colours like Sakhir Gold and Ascari Blue join the palette, while the 23-inch wheels enhance its aggressive stance. It’s less flamboyant than a Lamborghini Urus but exudes quiet confidence, perfect for the introverted Aussie performance enthusiast.
My Experience: In Satellite Silver, parked at Bondi Beach, it drew stares without screaming for attention. The carbon-fibre front spoiler and rear trim (optional) add a premium touch.
Ownership Tip: Opt for the Carbon Package for a bolder look, but the standard matte grey accents are sleek enough.
Luxurious and Practical Interior
Inside, the RS Q8 Performance blends luxury with sportiness. The cabin mirrors the standard Q8 but adds RS-specific touches: Alcantara-wrapped steering wheel, carbon twill inlays, and heavily bolstered Sport Seats Plus with Nappa leather and honeycomb stitching. The dual-screen MMI touch system (10.1-inch infotainment, 8.6-inch climate control) includes RS-specific virtual cockpit layouts, real-time driver assistance displays, and app integration. While not as flashy as BMW’s iDrive, it’s intuitive, with seamless wireless Apple CarPlay and Android Auto. The optional $9,700 Sensory Package adds massaging seats, a suede headliner, and a 23-speaker Bang & Olufsen 3D sound system.
For practicality, the 2,998mm wheelbase offers ample knee and legroom for adults (I’m 6’1” and fit comfortably in the rear, though headroom is tight due to the coupe-style roofline). The boot provides 605L with seats up, expanding to 1,755L when folded, with a flat floor and space-saver spare.
My Experience: The seats kept me comfortable during a 3-hour drive from Sydney to the Blue Mountains, and the sound system made every track crystal clear. Rear passengers enjoyed the four-zone climate control, but taller folks may graze the roof.
Ownership Tip: Avoid the middle rear seat for adults; it’s best for kids.
Safety and Ownership Costs
Safety is robust, with adaptive cruise control, lane change warning, rear cross-traffic alert, and surround-view cameras. The Q8 range earned a five-star ANCAP rating in 2019, but this expires in 2025 and doesn’t apply to V8 models like the RS Q8 Performance. Servicing costs align with the standard RS Q8: $4,690 for a 5-year plan or $5,720 for the Audi Advantage package (7-year warranty, extra services, and roadside assistance).
My Experience: The surround-view cameras were a lifesaver navigating tight Sydney parking.
Ownership Tip: Budget for high fuel and tyre costs, given the 12.2L/100km rating and Pirelli P0 tyres.
Is It Worth $255,800?
At $255,800 (before on-roads), the RS Q8 Performance is $27,500 pricier than its predecessor and $24,800 more than the standard RS Q8. However, it includes carbon-ceramic brakes (previously a $19,500 option), lightweight 23-inch wheels, and premium features like Nappa leather and a 730W Bang & Olufsen system. Compared to the BMW X6 M Competition ($259,900) or Porsche Cayenne Turbo GT ($351,600), it’s a relative bargain, offering similar performance for less. It’s pricier than the standard RS Q8 ($231,000) but justifies the cost with extra power and kit.
My Experience: For Aussie buyers in Sydney or Melbourne craving a do-it-all SUV, it’s a tempting alternative to a Urus ($100,000 more).
Ownership Tip: Test drive at an Audi dealer to feel the V8’s grunt before committing.
The 2026 Audi RS Q8 Performance is a masterclass in versatility. Its 471kW V8, track-honed dynamics, and luxurious cabin make it a family SUV that can embarrass sports cars. While the $255,800 price and 12.2L/100km thirst are steep, the included carbon-ceramic brakes, lightweight wheels, and premium features soften the blow. My Sydney drives confirmed it’s as practical for daily commutes as it is thrilling on twisty roads or tracks. For Aussies seeking the ultimate super SUV, it’s a must-test.
