The brand new Audi RS 5 is such a technological showcase it ought to include the enduring ‘Vorsprung durch Technik’ promoting slogan plastered throughout it. That advertising and marketing phrase meant “progress by expertise” and, as a result of it was in German and we didn’t fairly perceive it, the slogan got here to suggest Teutonic effectivity, experience, innovation and premium high quality.
Okay, in recent times it has develop into much less central to Audi‘s output. It doesn’t appear to suit an advert for a cost-effective A1 hatchback or Q3 household SUV so effectively. However Audi has simply unveiled a brand new and really worthy Vorsprung durch Technik candidate to the world.
Its newest model of the RS 5 is the model’s first ever high-performance plug-in hybrid however, extra importantly for the broader motoring world, it options some state-of-the-art Audi-style motoring tech.

First the essential headlines in regards to the automobile: it’s the most recent technology of Audi’s scorching rod four-wheel-drive station wagon (Avant) or sedan (at current solely the sedan is introduced for the US, each appear probably elsewhere). The 630 hp of energy comes from a 2.9-liter petrol V6 plus a 130-kW electrical motor with a 25.9-kWh battery below the trunk and an eight-speed Tiptronic gearbox.
We’ve reported on totally different generational improvements for the RS 5 extensively over the years. This time it’s sufficient to say that the automobile appears like an indignant monster in both wagon or sedan type. It’s jammed with high-end equipment and is just about what you’d anticipate from a German model’s prime quality premium sports activities sedan or wagon.
Nevertheless it’s the tech behind the rear transaxle system that’s thrilling the world’s auto engineers. It guarantees dealing with on a brand new degree. The pioneering system is price highlighting however will take slightly explaining. Nevertheless it’s price it to understand the science. Maintain tight, right here goes…

The Dynamic Torque Management within the 2026 Audi RS 5 is the fruits of over 45 years of Audi’s ‘quattro’ all-wheel drive improvement. It marks a big shift from purely mechanical components to high-speed electronics to unravel one in all Audi’s longest-standing dealing with criticisms: understeer.
That is the issue: in a traditional automobile, the engine sends energy equally to each wheels on any axle. On a decent nook the wheels want to show at totally different speeds however can’t, in order that causes issues like wheelspin or understeer. It’s like in case you are rowing a ship. If you wish to flip proper, you row more durable on the left facet, with out differential torque you possibly can’t do this.
Managing torque means pushing extra energy to the wheel that wants it most, to assist the automobile flip corners extra effectively. The RS 5 is the primary to do that electro-mechanically, sending additional energy to the surface wheel throughout a nook to “push” the automobile into the flip, making it really feel lighter and sharper. That precept isn’t new. However as a result of the RS 5 makes use of a computer-controlled electrical motor to shift that energy (as a substitute of ready for mechanical components to maneuver), it occurs virtually immediately – quicker than you possibly can blink.
Earlier programs have been reactive, fixing a slide after it begins. This electrical system is proactive as a result of it calculates what the automobile wants – 200 occasions each second – to stop sliding or understeering earlier than it occurs. It’s a world first in any manufacturing automobile and goals to make the heavy, highly effective RS 5 (approx. 2.5 tons) deal with like a small, nimble go-kart.

Audi has all the time been a pacesetter in torque tech. Its early programs used a handbook swap to lock the rear wheels collectively for traction in snow. Subsequent Audi used ABS to “pinch” the brakes on the within wheel throughout a flip, tricking the differential into sending extra energy to the surface. The Sport Differential of 2008 used hydraulic clutches and gears to push torque to the surface wheel below load. This new system replaces these clutches with an 8-kW electrical motor eradicating the delay of hydraulic stress increase, permitting on the spot torque shifts.
That is all important in engineering phrases: Audi designed it to deal with the tendency of earlier RS fashions to push broad in corners. By shifting as much as 2,000 Nm (1,475 lb.ft) of torque between wheels, it will possibly now actually drive the automobile to rotate as required. In contrast to mechanical programs that want you to be on the accelerator to work, this electrical system can vector torque even if you are braking or coasting.
For the primary time, it permits a drift mode that may ship as much as 100% of the rear drive to a single outer wheel, permitting for managed, tire-smoking slides that have been beforehand not possible for quattro programs.
Its rivals, the BMW M3 or Mercedes-AMG C63 depend on slower mechanical drift modes. The M3’s system is about conventional purist rear-wheel-drive, counting on the motive force’s ability to steadiness the throttle and steering. The C63 is extra brutal, making it straightforward to start out a slide – however tougher to handle the heavy sports activities sedan when you’re hurtling sideways.
