The 2027 Audi RS5 is the most powerful RS5 ever built. Its twin-turbocharged 2.9-litre V6 now makes 503 horsepower on its own, paired with a 174-horsepower electric motor for a combined system output of 630 horsepower and 609 pound-feet of torque. It reaches 62 miles per hour in 3.6 seconds, and professional testers believe the real number is closer to 3.3 seconds. It has 44 miles of electric-only range for daily commuting. And when you engage the Torque Rear mode, which sends 85 percent of total torque to the rear axle and disables stability control, one experienced driver described it as effortlessly skidding through a closed course in a smokey, perfect slide around a central cone. This Is Not the RS5 You Remember.
I want to start with a confession. The outgoing RS5, as accomplished as it was, had started to feel like an RS car that had forgotten what RS was supposed to mean. It was fast, beautifully built, and supremely comfortable. But it had smoothed out so many edges, softened so many responses, and prioritized so much compliance that the thing which originally made RS vehicles exciting, the sense that you were dealing with something genuinely aggressive, had largely drained away.
The 2027 RS5 fixes this. It fixes it dramatically, almost violently, and in ways that nobody fully anticipated given that the big story was supposed to be the plug-in hybrid powertrain addition. Let me walk you through exactly what happened.
The Powertrain That Changes Everything
The 2027 RS5 is Audi Sport’s first-ever plug-in hybrid RS model, and the engineering team did not approach this transition timidly.
The foundation is Audi’s familiar 2.9-litre twin-turbocharged V6, but it has been overhauled to produce 503 horsepower on its own, already nearly 60 horsepower more than the outgoing RS5 Competition made at its absolute peak. Mounted between the engine and the eight-speed automatic transmission sits an electric motor producing 174 horsepower and 339 pound-feet of torque. Together, the combined system output reaches 630 horsepower and 609 pound-feet of torque.
To put that in direct context, the outgoing RS5 produced 444 horsepower. The new car produces 630. That is a 186 horsepower increase delivered through electrification. The jump is enormous.
The 22-kilowatt-hour battery pack, with 22 kilowatt-hours usable, sits beneath the cargo floor and provides approximately 44 miles of pure electric range under European test cycle conditions. Real-world American driving will likely produce a figure closer to 35 to 40 miles, which is still enough to handle the average American daily commute on electricity alone before the combustion engine ever starts. On a 240-volt Level 2 home charger, a full recharge from depleted to 80 percent takes approximately 2.5 hours.
The transitions between electric and combustion power are described by professional testers as seamless and non-intrusive. In the calmer driving modes, the engine produces a nice, constant burbly sound and feel rather than an annoying buzzy drone. In Dynamic mode, the exhaust gets noticeably throatier, the chassis tightens up, and the power delivery takes on an urgency that feels genuinely more than the already impressive base numbers suggest.
Then there is the red Boost button.
The Red Button That Every Driver Will Press Immediately
Mounted in a position described as tantalizingly close to your left thumb, the Boost button unleashes the RS5’s full 630-horsepower system output for 10 seconds of maximum acceleration. This is the mechanism through which the car’s performance ceiling is accessed in a dramatic, deliberate, addictively enjoyable way.
Every first drive account mentions the button. Every professional tester describes pressing it repeatedly. The 10-second window is enough for a full highway passing maneuver, a dramatic on-ramp entry, or simply the experience of understanding in your body what 630 horsepower in a sports sedan actually feels like. And because the electric motor’s torque arrives instantaneously rather than waiting for turbo spools, the initial sensation is more violent and more immediate than the 3.6-second zero to 62 figure might suggest.
Multiple experienced automotive journalists who drove this car in testing conditions stated that 3.6 seconds feels conservative. Given that the previous generation tested at 3.3 seconds to 60 miles per hour with 444 horsepower, the new car’s real-world result with 186 more horsepower should, by physics and driver intuition alike, be quicker.
The Drift Mode Nobody Expected From an Audi
Here is the part of the story that genuinely surprised the entire automotive press corps when the first drive reviews arrived, because Audi is not a brand with a history of putting drift modes in its production vehicles.
The 2027 RS5 features a new mode called Torque Rear. Engaging it immediately disables stability control and configures the car’s new rear differential to operate at maximum aggression. Combined with the revised center differential’s ability to send 85 percent of total available torque to the rear axle, the result is a vehicle that one professional driver described, in direct and enthusiastic terms, as effortlessly skidding through a closed course, performing a perfect slide around a central cone after a smokey launch, potentially the easiest-drifting 600-plus-horsepower car on the current market.
To understand why this matters technically, you need to understand the AWD system behind it. The 2027 RS5 uses what has been described as the most complicated and over-engineered quattro all-wheel drive system ever installed in any Audi product. A small electric motor lives on the rear differential and can shuffle power between the right rear tire and the left rear tire independently. The center differential manages the front-rear split. The combination gives Audi’s engineers an unprecedented level of control over torque distribution at every individual wheel in real time.
Torque Rear mode weaponizes all of this complexity in service of deliberate rear-end playfulness. Depending on driving conditions, the system can also send up to 70 percent of torque to the front wheels when grip demands stability rather than spectacle. The same hardware serves both purposes with equal competence.
Audi specifies that Torque Rear is intended for non-public roads only, which is the legally appropriate disclaimer for a mode that disables stability control and maximizes rear bias in a 630-horsepower all-wheel-drive sedan.
The Weight Problem That Cannot Be Ignored
Every professional review of the 2027 RS5 addresses this honestly, and so will I, because intellectual honesty matters more than cheerleading.
The new RS5 weighs approximately 5,192 pounds. The outgoing RS5 weighed roughly over 1,000 pounds less. Every pound of that difference comes from the hybrid system, primarily the 22-kilowatt-hour battery pack located beneath the cargo floor. This weight increase is the fundamental trade-off of plug-in hybrid technology in a performance vehicle, and it affects the driving experience in detectable ways.
At the closed course handling events where professional testers experienced the car, the weight was noticeable in transitions and changes of direction that require the mass to be managed rather than ignored. The car handles this mass better than the number alone suggests, partly because the battery placement low and centrally improves the weight distribution relative to an equivalent conventional heavy vehicle, and partly because the sophisticated AWD system compensates aggressively. But 5,192 pounds is 5,192 pounds, and the laws of physics apply regardless of how sophisticated the electronics are.
Some reviewers also noted that the transmission behavior shows occasional funkiness in certain driving conditions, particularly in the transitions between electric and combustion modes under specific throttle inputs. This is described as a known characteristic rather than a defect, one that software updates may address over time but that exists in launch examples.

The Interior and the Driving Modes
The cabin received the full RS treatment alongside the powertrain overhaul, and the result is a cockpit that finally matches the vehicle’s aggressive new character with equally aggressive interior presentation.
Heated, cooled, and massaging front seats come standard. The dashboard technology suite reflects Audi’s current generation architecture with a high-tech display layout that keeps information accessible without cluttering the visual field. The RS-specific details, including the red Boost button and the drive mode selector that access Torque Rear, are integrated in a way that feels purposeful rather than added on.
In Dynamic mode the character transforms noticeably. The exhaust note deepens. The chassis tightens. The throttle response sharpens. The combination of these simultaneous changes produces a vehicle that one tester described as feeling like there is suddenly a lot more power on tap, measured enough for daily driving but urgent enough to feel genuinely special when you want it to be.
In the calmer Comfort and Efficiency modes, the RS5 is a refined, quiet, surprisingly efficient daily companion. This is the version of the car that runs to the office on electricity and charges in the parking garage. The transition between these two characters, the daily EV commuter and the 630-horsepower drift-capable sports sedan, is the most impressive achievement of the entire engineering exercise.
