Audi S4 vs Rivian R1S

What's the difference?

The S4 and S5 range continues to represent a great formula for performance you can live with every day. They're arguably the sweetest balance Audi produces, actually. All come fantastically equipped, with cabins that feel truly special, and we’re lucky they can be had in a choice of five bodystyles.  

While there are some obvious signs that the R1S is Rivian’s first mass-market vehicle, the good news for the company is that its problems are not impossible to overcome. The suspension needs retuning to improve the ride quality and the multimedia system’s software needs upgrading. But even with those issues the R1S left a positive impression.

This is a very stylish SUV with great space and excellent performance, that also happens to be electric, rather than relying on being electric as its primary selling point.

Rivian has put more effort into the design and finishes than many of its EV rivals and the result is a vehicle that can genuinely compete with the established premium players with more credibility.

The only catch is there’s no clear timeframe for when, or even if, this generation of R1S will make it to Australia. The brand has repeatedly spoken of its hopes of entering the market here without locking anything in, but given the current state of the EV sales it may pay off to wait until the conditions are right for a new, premium player to try its luck here.

The S4 sedan and Avant have scored the bulk of design updates, with all new and recontoured side panels including the sedan’s C-pillar matching what was applied to the A4 earlier this year. 

This is paired with new front and rear facias and lighting for a subtle but extensive rework of the fifth-generation S4’s conservative look. 

The S5 Sportback, Coupe and Cabriolet get S5-specific new lighting and facias, but no sheetmetal changes. As before, the Coupe and Cabriolet ride on a 60mm shorter wheelbase than the Sportback, sedan and Avant.

The S5s also get Matrix LED headlights as standard which do a neat animated sequence when you unlock the car. 

Other visual hallmarks include new S4-specific 19-inch wheels, with S5 stepping up to its own unique 20-inch wheel. The six-piston front brake calipers are appropriately painted red, and there’s S-specific adaptive dampers under there too. All variants aside from the Cabriolet get a lip spoiler on the rear.

On the inside, there’s a new centre console and bigger 10.1-inch multimedia screen, while the Audi Virtual Cockpit driver instrument display now offers a hockey stick-style rev counter in additional to traditional dial layouts.

Design is another area where Rivian has carved out a unique position for itself. Whereas other brands, including Tesla, have focused on simplicity and aerodynamic efficiency, Rivian has given the R1T a unique style that looks interesting, different and most definitely not plain.

The oval daytime running lights make every R1S and R1T stand out from a mile away, even on LA’s busy freeways. The overall design is high quality and manages to strike a good balance between aesthetics, aerodynamics and practicality - even if it doesn’t suit everyone’s personal taste.

The cabin is worth highlighting in particular, because rather than go for the ‘minimalist’ look that so many brands are going for these days, with as little switchgear and different trims as possible to keep costs down, Rivian has opted for something more complex and, frankly, more impressive.

There’s a level of craftsmanship, a great mixture of premium materials (including some striking light wood options) that make the R1S feel like a stylish and relaxed environment inside the cabin. Our particular example had a great mixture of colours, textures and patterns that really elevated the cabin experience.

The technology is also nicely integrated into the design, rather than being the focal point, like so many other modern electric vehicles. It still offers the same level of technology - a pair of screens - but doesn’t rely on them to carry the design of the interior.

The biggest practicality change among the five S4 and S5 variants is their upgrade to the latest version of Audi’s MMI multimedia system, which steps up to a 10.1-inch touchscreen and drops the scroll wheel from the centre console.

It also boasts ten times the computing power of the version it replaces and uses this and an on-board sim card to access Google Earth maps for navigation and Audi Connect Plus that offers driver information such as fuel prices and parking information as well as point of interest search and weather information, plus the ability to make emergency calls and seek roadside assistance.

There’s also a wireless phone charger, but using Apple CarPlay will still require a cord as per Android Auto.

I only drove the S4 Avant and S5 Sportback at their media launch, which are clearly the most practical of the five, but from our experience with the previous versions, each looks after its occupants well in terms of space and storage. Back seat accommodation is clearly not a priority in the Coupe and Cabriolet, but there’s three other variants if that’s what you’re looking for. 

The Cabriolet can open its automatic folding soft top within 15 seconds, at speeds of up to 50 km/h.

The R1S comes standard as a seven-seat SUV, split across three rows (two in the first row, three in the second row and two in the third row). Space across the three rows is fairly typical for an SUV of this size, which is to say generous up front, good in the second row and a little bit tight in the back.

What is good though, is the length of the cabin allows for quite a spacious boot even with the third row in use, which is definitely not something all seven-seat SUVs can claim. Using a direct conversion from Rivian’s specifications that list cargo capacity in cubic feet, the R1S has a claimed 498 litres with the third row in use and up to 1331L with the third row folded down. There’s also 314L under the bonnet and another 144L underneath the boot floor (although that comes at the expense of a spare tyre).

As mentioned in design, Rivian has nicely integrated the technology into the cabin, with the 12.3-inch digital driver display and 15.6-inch central multimedia touchscreen feeling like a natural part of the car rather than a centrepiece. Rivian has also managed to incorporate eight USB-C charging ports spread around the cabin to keep everyone’s devices charged up.

However, while the technology is nice from an aesthetic design perspective, the same cannot be said about its useability. Like Tesla, Rivian has opted to go it alone with its multimedia system and has developed its own Google-based software that is not compatible with either Android Auto or Apple CarPlay. That would be acceptable, although still disappointing, if the system worked as well as Tesla’s, however the Rivian system is very slow. It repeatedly took several seconds to load between the various functions, which may not sound like long, but when you’re trying to get back to the navigation so you don’t miss your freeway exit a few seconds can make a big difference.

But, honestly, in this day-and-age, systems like this should work quickly and seamlessly, so it’s an area Rivian needs to improve.

On a positive note, Rivian does have some cool accessories for the R1S including what it calls a ‘Camp Speaker’ which is a US$400 option that it integrates into the sound system but is also removable, so you can pull it out of the centre console and listen to your music if you’re around the campfire or having a picnic.

When we drove the R1T in 2023 Rivian was still in the ramp up stage of production and was limited with what it could offer customers. Fast forward to 2025 and the brand now has both the R1T and R1S available with dual or tri motor powertrains, with a quad-motor powertrain expected by the end of the year.

The R1S Dual Standard begins the range at US$75,900 (approx. A$118,000), the R1S Dual steps it up to US$83,900 (A$130k) and the R1S Tri-motor completes the current line-up at US$105,900 (A$165k). While those prices are definitely in the premium end of the market the R1S is actually cheaper than the Tesla Model X, which is still on sale in the US market, and starts at US$86,630 (A$135k) and stretches to US$101,630 (A$158k).

For more context, the Audi Q8 e-tron starts at US$74,800, the BMW iX from US$87,250 and the Mercedes-Benz EQE from US$77,900.

Standard equipment across the range includes the 12.3-inch digital instrument display, 15.6-inch multimedia touchscreen, dual-zone climate control, heated and ventilated front seats, heated steering wheel, eight-way power adjustable driver and passenger seat and panoramic glass roof, so it certainly has premium levels of equipment.

We drove the range-topping RS1 Tri-motor which, aside from an extra motor, gets standard 22-inch alloy wheels, a dynamic glass roof, a soft-touch suede textile headliner as well as unique colour and trim options.

Audi has taken an ‘if it ain’t broke’ approach with the mechanicals, with all S4 and S5 models unchanged with this update. So the centrepiece continues to be the single-turbocharged 3.0-litre V6 that produces 260kW and 500Nm, with the latter available from a broad 1370-4500rpm.

The rest of the drivetrain is also unchanged, with the venerable but excellent ZF eight-speed torque converter auto paired with the Quattro all-wheel drive system that can send up to 85 per cent of drive to the rear wheels. 

As mentioned earlier, there are currently three versions of the R1S available, each with a different powertrain. 

The Dual Standard AWD has, unsurprisingly, dual motors (one at the front and one at the rear) which make a combined 397kW/827Nm. That’s enough for it to launch 0-60mph (0-96km/h) in just 4.5 seconds. The R1S Dual AWD has the same power, torque and acceleration figures, however it gets Rivian’s Large battery, which we’ll detail below.

The Tri-Motor AWD obviously has three motors, one on the front axle and two on the rear, which naturally provide more power, 633kW/1495Nm. With so much power and torque the Tri-motor is wickedly fast, taking just 2.9 seconds to launch 0-60mph.

If, for some reason, the Tri-Motor isn’t fast enough for you, Rivian has released the details on the Quad-Motor. It will have two motors on each axle providing a staggering 764kW (that’s 1025-horsepower!) and 1624Nm, enough to rocket it from 0-60mph in just 2.6 seconds and across the quarter mile in 10.5 seconds.

Official combined fuel figures range from 8.6L1/00km for the S4 sedan to 8.8L/100km for the Avant, Coupe and Sportback, while the heavier Cabriolet steps up to 9.1L/100km. 

All are pretty good considering their performance potential and the size of these cars, plus the fact that they only require 95 RON Premium Unleaded fuel.

All have a 58-litre fuel tank, which should enable a range of at least 637km between fills based on the Cabriolet’s figure.

Rivian offers three different battery types across the three variants, each with a different driving range. The R1S with the Standard battery (92.5kWh) has a claimed 434km driving range, the R1S Dual with Large battery (109.4kWh) extends that to 530km, while the Tri-Motor comes standard with the Max battery (141.5kWh) that has an impressive 597km of range.

It is worth noting, though, that those range claims are based on US EPA estimates, rather than either the WLTP or NEDC methods usually used.

Charging times vary depending on the type of charger used, in the US Tesla has given access to its network to other EV brands and the Rivian is available with a plug adaptor to use a Tesla charger. The R1S is capable of charging up to 220kW, which means it takes approximately 40 minutes to take the battery from 10 to 80 per cent. 

The S4 and S5 range were already an excellent balance between everyday comfort and a genuine sporting edge, and nothing has changed with this update.

I spent time behind the wheel of the S4 Avant and S5 Sportback at their media launch, and both managed to deliver the proper Audi luxury experience over some pretty rough rural roads, while always feeling a bit more sporting than a regular A4 or A5. That’s with the Drive Select left in the default mode, but you can shift that sporting personality up a few notches (while scaling back the comfort), by selecting Dynamic mode. 

My preferred means of adjusting their personality is by simply tugging the transmission selector back to activate S mode, which livens up the engine and transmission without stiffening up the suspension. 

Across the five S4 and S5 bodystyles, there is some variance in performance potential, with the S4 sedan and S5 Coupe topping the performance chart with 0-100km/h boasts of 4.7s, with the S5 Sportback trailing them by 0.1s, the S4 Avant by a further 0.1s and the Cabriolet managing a still-fast 5.1s claim.

Another area I consider the S4 and S5s to get just right is their exhaust note. It is adaptive, but there’s nothing synthetic about it, and the generally muted and distinctly V6 burble is always there to remind you that you’re aboard a proper performance model, but not in such a way that it will annoy you, or your neighbours. Polite performance, if you will.

The R1S and R1T are Rivian’s first mass-produced cars, and it shows. It’s not all bad news by any stretch, but there are some major issues the brand will need to address in the future if it wants to succeed globally (or even just in the US). 

The biggest issue is the ride, which just doesn’t feel as well resolved as the more established brands that have been designing, developing and building cars for decades. The R1S isn’t bad to drive by any stretch, but the ride is too firm at times and it also lacks control and feels too soft at others. 

All R1S grades come standard with Air Suspension that has multiple levels of firmness and can adjust the ride height. However, in the ‘normal’ setting the ride feels too busy, with the heavy (3096kg) SUV skittering over the imperfections in the road rather than absorbing them. The problem is, if you adjust the suspension to the softer setting it lacks control and has a tendency to bounce over bigger bumps and take a few seconds to settle. This was particularly noticeable on LA’s concrete freeways, but it would be an issue on any road with undulations or joints.

But while the ride needs improvement, the R1S has strengths in other areas - namely performance. The Tri-motor AWD we sampled had immense punch from its three motors and it certainly felt like 633kW and 1495Nm was on tap. We didn’t test its acceleration claim officially, but any take-off could be made into a rapid one with just a squeeze of the accelerator pedal. 

The R1S is also capable of towing up to 3500kg, so it’s a strong and capable SUV too, rather than just a speedy EV.

Another strength is the regenerative braking system. There are multiple settings but we found the lowest regen was the best option, as it still provides powerful regen but is more progressive than the more powerful modes.

The R1S comes loaded with safety equipment across the range, including eight airbags, adaptive cruise control, autonomous emergency braking, blind spot monitoring, forward collision warning, lane departure warning, lane keeping assist and rear cross-traffic alert.

It also comes with what’s called the ‘Rivian Autonomy Platform’ that includes 11 cameras and 12 ultrasonic sensors for mild-autonomous functionality in specific circumstances, such as freeway driving or on well-marked roads. 

Audi continues to offer a three year, unlimited kilometre warranty, which is in line with BMW but lags behind the five years offered by Mercedes-Benz these days. This also contrasts with the five year norm among mainstream brands, which is punctuated by the seven year warranties of Kia and SsangYong.  

Service intervals are a convenient 12 months/15,000km though, and the same five year ‘Audi Genuine Care Service Plan’ offers capped price servicing for the same $2950 total over five years applies to all S4 and S5 variants. This is only marginally more than the plans offered for regular petrol A4 and A5 variants, so you’re not being stung for the thoroughbred versions.

Rivian offers a four-year/80,000km warranty for the R1S vehicle as a whole, as well as a separate battery pack and drivetrain specifically. The Standard battery is covered for eight years/190,000km while the Large and Max batteries are covered for eight years/240,000km.

As for servicing, Rivian uses an app-based system, which allows owners to schedule a service at any time via the app and then either have a Rivian technician come to your home for a small service or drop it off at a service centre if it’s a bigger job. The app is also connected to the car, so if the car’s own diagnostic system recognises a problem, it can prompt you to book a service proactively.
