The new Audi RS 5 is such a technological showcase it should come with the iconic ‘Vorsprung durch Technik’ advertising slogan plastered all over it. That marketing phrase meant "progress through technology" and, because it was in German and we didn’t quite understand it, the slogan came to imply Teutonic efficiency, expertise, innovation and premium quality.

Okay, in recent years it has become less central to Audi‘s output. It doesn’t seem to fit an ad for an economical A1 hatchback or Q3 family SUV so well. But Audi has just unveiled a new and very worthy Vorsprung durch Technik candidate to the world.

Its latest version of the RS 5 is the brand’s first ever high-performance plug-in hybrid but, more importantly for the wider motoring world, it features some state-of-the-art Audi-style motoring tech.

First the basic headlines about the car: it’s the latest generation of Audi’s hot rod four-wheel-drive station wagon (Avant) or sedan (at present only the sedan is announced for the US, both seem likely elsewhere). The 630 hp of power comes from a 2.9-liter petrol V6 plus a 130-kW electric motor with a 25.9-kWh battery under the trunk and an eight-speed Tiptronic gearbox.

We’ve reported on different generational improvements for the RS 5 extensively over the years. This time it’s enough to say that the car looks like an angry monster in either wagon or sedan form. It’s jammed with high-end kit and is pretty much what you’d expect from a German brand’s top of the range premium sports sedan or wagon.

But it’s the tech behind the rear transaxle system that’s exciting the world’s auto engineers. It promises handling on a new level. The pioneering system is worth highlighting but will take a little explaining. But it’s worth it to grasp the science. Hold tight, here goes...

The Dynamic Torque Control in the 2026 Audi RS 5 is the culmination of over 45 years of Audi’s ‘quattro’ all-wheel drive development. It marks a significant shift from purely mechanical parts to high-speed electronics to solve one of Audi’s longest-standing handling criticisms: understeer.

This is the problem: in a normal car, the engine sends power equally to both wheels on any axle. On a tight corner the wheels need to turn at different speeds but can’t, so that causes problems like wheelspin or understeer. It’s like if you are rowing a boat. If you want to turn right, you row harder on the left side, without differential torque you can’t do that.

Managing torque means pushing more power to the wheel that needs it most, to help the car turn corners more efficiently. The RS 5 is the first to do this electro-mechanically, sending extra power to the outside wheel during a corner to "push" the car into the turn, making it feel lighter and sharper. That principle is not new. But because the RS 5 uses a computer-controlled electric motor to shift that power (instead of waiting for mechanical parts to move), it happens almost instantly – faster than you can blink.

Previous systems were reactive, fixing a slide after it starts. This electrical system is proactive because it calculates what the car needs – 200 times every second – to prevent sliding or understeering before it happens. It’s a world first in any production car and aims to make the heavy, powerful RS 5 (approx. 2.5 tons) handle like a small, nimble go-kart.

Audi has always been a leader in torque tech. Its early systems used a manual switch to lock the rear wheels together for traction in snow. Next Audi used ABS to "pinch" the brakes on the inside wheel during a turn, tricking the differential into sending more power to the outside. The Sport Differential of 2008 used hydraulic clutches and gears to push torque to the outside wheel under load. This new system replaces those clutches with an 8-kW electric motor removing the delay of hydraulic pressure building up, allowing instant torque shifts.

This is all significant in engineering terms: Audi designed it to address the tendency of previous RS models to push wide in corners. By shifting up to 2,000 Nm (1,475 lb.ft) of torque between wheels, it can now literally force the car to rotate as required. Unlike mechanical systems that need you to be on the accelerator to work, this electric system can vector torque even while you are braking or coasting.

For the first time, it allows a drift mode that can send up to 100% of the rear drive to a single outer wheel, allowing for controlled, tire-smoking slides that were previously impossible for quattro systems.

Its rivals, the BMW M3 or Mercedes-AMG C63 rely on slower mechanical drift modes. The M3’s system is about traditional purist rear-wheel-drive, relying on the driver’s skill to balance the throttle and steering. The C63 is more brutal, making it easy to start a slide – but more challenging to manage the heavy sports sedan once you’re hurtling sideways.

The eventual holy grail is one electric motor per wheel, and nothing else.

Tesla has had torque vectoring technology (or very similar torque management via independent electric motors) significantly earlier than the Audi RS 5 PHEV's "Dynamic Torque Control" system highlighted in that article. The Audi system's key innovation is an electro-mechanical torque vectoring setup in the rear transaxle, using a dedicated 8-kW electric motor/actuator for rapid, proactive torque shifts between the rear wheels (up to 2,000 Nm difference, recalculated 200 times per second). Audi claims this as a world-first in production cars for this specific electro-mechanical approach in a hybrid setup, evolving from their earlier mechanical/hydraulic quattro systems. However, Tesla has implemented torque vectoring capabilities much earlier through software-controlled independent electric motors: Since 2014–2015 — With the introduction of dual-motor AWD in the Model S (and later Model X), Tesla described dynamic torque shifting between front and rear motors at millisecond levels for better traction, efficiency, and handling. Elon Musk highlighted this in 2014 announcements as a key advantage over traditional AWD. 2018 — Tesla launched Track Mode on the Model 3 Performance, explicitly using motor torque to control rotation and apply torque bias (e.g., rear bias to help turn-in). It relies on the front/rear motors for yaw control and can command up to 100% torque bias. This is often described as torque vectoring via software and motors, though early versions supplemented with brake-based vectoring. 2022 — The Model S Plaid's Track Mode introduced full lateral torque vectoring using its dual rear motors to independently adjust torque split across the rear wheels (sending more to the outside wheel for rotation in corners). Tesla emphasized this provides faster adjustments than mechanical differentials in ICE cars, improving turn-in, yaw control, and corner-exit acceleration. Tesla's approach leverages the inherent advantages of electric motors (instant response, no mechanical delays) for axle-to-axle and (in tri-motor setups like Plaid) lateral vectoring on the same axle. It's been a core part of their performance software updates for years, well before Audi's 2026 electro-mechanical rear-specific system. In short: Tesla's torque vectoring tech dates back at least to 2014
So you hyping tech as new that's 12 years old is a bit embarrassing .

I'm a great Audi enthusiast but I really don't want to drive a car weighing two and a half tons and kitted out with technology I don't understand, as it's likely that no-one else will understand it when it goes wrong.
One of my local dealership's engineers told me that EVs and hybrids were the bane of their lives. They all understand mechanics, but he said that often faults were due to software, over which they had no control (or expertise). He even proffered the fact that a lot of customers buying new EVs or hybrids had sought to return them as 'not fit for purpose'.
This from a high-end brand too.

Sorry, a 5200lb vehicle will never feel like a "nimble go-kart".

@Everyone who wants a battery beater. Go buy one. Sit it in all day. It's what you're doing waiting for your battery to charge anyways. Leave the petrol cars to us.
