Volkswagen Id.5 vs Audi RS4

What's the difference?

At long last, the ID.5 GTX arrives to make a different pitch than many of its electric rivals. Less about straight-line speed and more about refinement and handling, this EV mid-sizer makes a case for itself, even if it’s not as good value as its ID.4 sibling.

What a way to send off this generation of Audi RS4 and RS5. The extra focus courtesy of those trick coil overs and drama from the exhaust plus the sharper gear changes deliver the best Audi has done with these RS products. 

There are some compromises, with the suspension favouring outright control over low-speed comfort. It’s also true that the current BMW’s M3 and M4 are more impressive, but when the products are nearly seven years fresher than Audi’s, what do you expect? 

Plus, those looking for a more restrained and polite fast executive sedan (or wagon) will gel with the Audi’s sophistication. There aren’t many of these Competition Plus RS4 and RS5s coming to Australia and they are impressive visually and from behind the wheel. It’s a fitting way to send off the current generations.

The key differentiator between the ID.4 and ID.5 is of course the ID.5’s descending coupe roofline. I think it grants the GTX more presence on the road, and I appreciate the touch of having a true three-dimensional spoiler piece atop the boot lid to round it out rather than a more common lip or roof-mounted extension.

Outside of this, the ID.5 sets itself apart from the rest of the Volkswagen range thanks to its curves rather than hard edges as well as contemporary light bar fittings, front and rear.

The overall visage is fresh but a tad conservative, especially compared to the more radical designs we’re seeing on new-to-the-market automakers like XPeng, or those looking to make a splash with their electric offerings, like Kia with its EV5.

There’s certainly something to be said for a more moderate approach, though, as it feels more resolved than many rivals.

Inside, to a degree, the ID.5 follows similar trends in the market, with a minimalist and screen-dominated dashboard.

The 12.9-inch central touchscreen unit is less overbearing than some 15+ inch units in other cars, and this combines with the sensible 5.3-inch digital instrument cluster to make it feel more like a car than a tech product on wheels.

Still, the minimalist theme prevails, with the ID.5’s interior being free of a space-consuming raised console or a smattering of buttons to interact with.

The seats in this GTX are particularly cool, with the single-piece backing like a Golf GTI, red stitching and nice material quality. 

It leaves you with the impression the ID.5 is modern but with the build quality and know-how of a storied automaker, which is a nice balance.

The RS4 Avant’s 'Progressive Red' metallic helps the black milled 20-inch alloy wheels pop. Its stance is hugely purposeful with wheels tucked right up in the blistered arches courtesy of the lowered ride height — it's how the Avant would have looked in a design sketch.

The visual bulk of the long-roofed RS4 gives it the sort of proportions motoring journalists love to wax lyrical about, even if plenty of buyers still prefer coupes or lifted SUVs. 

The RS5's more flowing, elegant lines match well with the Navarra Blue paint work, silver-accented wheels and conventional leather-appointed seats within. 

Both cars have effectively identical front cabins reflecting Audi’s classy and sleek design language. The integration of technology is pretty good and the RS4’s additional red styling pack really makes it feel sporty within.

First, the less-good. The minimalist and button-free interior will be a major downside for many. Pretty much everything in the ID.5’s cabin is touch-based. There’s not even a stop/start button, you just sit in the car and it’s ready to go. Additionally, it relies on the now-maligned touch sliders below the multimedia screen for volume and temperature adjustment. Never fun to use on the move. Even the buttons on the steering wheel are the touch-based haptic-feedback kind.

At least the software shapes up. It’s easy enough to navigate, and has a slew of straightforward menus. It’s also backed by enough processing power, with swift responsiveness, and the panel quality is good too, with a sharp, high-resolution finish.

This can be a double-edged sword, though. The high-resolution leads to small shortcut icons across the top of the main screen. While I’m glad the ID.5 has these so you can swap between things like the car’s settings menu and, say, Apple CarPlay easily, it takes some accuracy to jab at while you’re trying to drive.

From there, though, the cabin is clever. Free from the trappings of buttons and a raised console, it feels spacious in every dimension and the seat comfort is excellent with lovely side bolstering and padding.

The seats feel quality, but I wonder whether the synthetic suede-style microfleece trim will age as well or be as easy to clean as cloth or leather. Worth thinking about if you plan to keep this car for a long time.

I even like the touch of having little flip-down armrests which almost makes it feel like you’re being silently propelled along in an armchair in the front seats.

You need these because there’s no traditional raised console with an armrest box. Instead there’s a flexible floating central console piece. It features a modular sort of design, where you can make use of either dividers or a drop-in bottle holder piece in either the upper or lower sections, depending on your preference. Remove these things entirely to have two massive trays.

Meanwhile, the lower section features a cubby with a wireless phone charger, and it also houses the dual USB-C ports with a sliding cover so you can keep the interior tidy. I like it.

There are large bottle holders in the doors, too, and another nice touch is the digital dash being perched on the steering column, so no matter how you adjust it, you can always see it.

The back seat is also excellent in the ID.4 and ID.5, featuring plenty of space for me behind my own driving position, at 182cm tall. There’s heaps of airspace for my knees, and because there’s a flat floor courtesy of this car’s dedicated 'MEB' platform, there’s plenty of space for your feet. It also makes the centre position usable by an adult, which is rare.

Soft trims continue in the doors, but my favourite feature of the ID.5’s rear bench is how the brand has thought to strongly contour the outer two seat backings so even they have plenty of side bolstering.

The backs of the front seats feature an upper pocket for phones and the like, and a larger lower pocket, while the doors feature a large bottle holder each. A drop-down armrest has three shaped cavities for bottles of all sizes, and behind it is a ski port door.

There are adjustable air vents and a touch panel to control the rear climate zone, but because of the low design of the central console, they’re basically on the floor. Nice to have them, but they might be hard to adjust for kids or the less mobile.

This will surprise you. The boot is bigger in the ID.5 than in the ID.4 despite this car’s descending roofline. Measuring 549 litres, it’s also good for the mid-size segment and features an under-floor storage area which is great for your charging equipment. However, there is no spare wheel, just an inflator kit, and also, the ID.5 doesn’t get a frunk like many of its electric contemporaries.

The RS4's cabin is excellent, with a good mix of physical buttons and responsive touchscreens for control. There’s enough storage space for this kind of vehicle, with good door bins and well-sized cupholders in the centre as well as USB-C and -A charge points. 

Audi’s multimedia system is friendly though the large touch targets and dark background aren’t as crisp as those fitted to the latest rivals. The screen isn't as big, either, measuring 10.1 inches for the multimedia item. The RS4 supports wireless Apple CarPlay and Android Auto.

That said, Audi’s 12.3-inch digital driver’s display with bright and poppy mapping software and generous customisation remains right at the head of the pack. 

There is a panel of switches below the touchscreen for climate control, physical selection of the five-or-so drive modes and a collection of helpful buttons on the perfectly-shaped and sized leather-appointed steering wheel.

It lacks F1 or DTM wow-factor compared to the C63 and M3 with their easy-access driver mode buttons and toggles on the steering wheel but the RS4's restrained looks will resonate with those that prefer a bit more elegance inside. 

Neither the RS4 nor RS5's back seats are designed for those over about 175cm. The RS4’s roof is a little higher so it is good enough for most adults but the RS5’s sloping profile compromises things. It has two individual buckets compared to the RS4’s three-wide bench. 

Rear seat passengers get air vents, an individual climate zone, bottle holders in the doors, USB charge points and ISOFIX attachments for the outboard seats, with matching top tethers in the seat backs.

The Audi RS4’s boot is a generous 505L with under floor storage and a netted area on the driver’s side. Folding the 40/20/40 split-fold bench increases space to 1495L. That said, the RS5’s 465L is still very good, though it is not quite as practical in the real world. 

Being fitted with roof rails makes for sleek integration of roof racks for the RS4 to slip roof pods, bike racks or whatever else you might choose to take on a trip away.

You'd expect the RS5 to be more popular given how uncool wagons are these days but Audi's whole thing is wagons — or Avants, for the initiated — so it makes sense that the RS4 Avant outsells the RS5 Sportback about two-to-one.

For the RS4 Avant’s basic asking price of $165,015, before on-road costs, you get luxury features such as LED headlights, an RS design package, Nappa leather upholstery, power-adjust seats, a Bang & Olufsen 19-speaker sound system and metallic paint on top of the significant changes to the RS4’s chassis and zingy 331kW V6. 

The RS5 is a little dearer, reflecting the addition of Matrix LED headlights that aren’t available on the wagon.

But we have the 'Competition Plus Pack', which is a $13,990 indulgence that swaps adaptive dampers for Audi’s 'RS Sport Suspension' coil over package with manual rebound and compression adjustment and height adjustment.

The cars sit 10mm lower than a normal RS4 but you can go to a dealer to move the ride height up or down from there. 

That’s not it, though. You also get a louder exhaust system with matte black pipes, fixed-ratio steering system, a retuned eight-speed automatic with more aggressive shifts, different rear differential programming, black exterior badging, 2.0kg lighter 20-inch Audi Sport wheels (in silver or black), special LED entrance lights and your speed limiter raised to 290km/h.

The 'Navarra Blue' RS5 pictured is a ‘basic’ Competition Plus. You can go further, as done with the RS4 Avant with its manual-adjust bucket seats ($1300), 'Interior Design Pack' in red ($3400), matte carbon exterior pack ($6300) and carbon trim, bringing its total cost to $191,405, before on-road costs. 

That makes the RS4 and RS5 the most affordable in their competitor set, below a BMW M3 Competition xDrive Touring ($183,500) and Mercedes-AMG C63 S E Performance hybrid, which is $187,900, before on-road costs.

Instead of a frunk there’s simply a mess of hardware under the bonnet which is largely related to the ID.5’s high-voltage and cooling systems, but what sets the GTX apart is the addition of a front motor to add to the standard rear one.

It’s not a huge power boost. The ID.4 already puts out 210kW/545Nm, and the front motor on the ID.5 simply adds 40 additional kW for totals of 250kW/545Nm (as the torque figures for the two don’t simply add together).

Its claimed 0-100km/h sprint time of 5.4 seconds isn't bad, especially compared to combustion equivalents, but it’s also not as breakneck fast as some of its EV rivals.

Instead, the additional motor for the ID.5 GTX is more about adding something to the handling equation, as well as the dependability of all-wheel drive and additional drive modes. More on this shortly.

Audi’s 2.9-litre twin-turbo petrol V6 has seen plenty of use across performance products from Audi and Porsche, including the Macan S and Audi S6. 

In the RS4 and RS5 Competition Plus, it develops the same 331kW (at 5700-6700rpm) and 600Nm (at 1900-5000rpm) as the regular car. This makes it an extremely flexible engine that delivers predictable punch anywhere in the power band.

That said, it lacks the explosive character of BMW’s twin-turbo inline six — the figures are only 15kW and 50Nm higher on paper yet the M3’s response is that much more ferocious. 

Audi’s RS division has tried to capture a bit more emotion, retuning the eight-speed torque converter automatic transmission for crisper shifts. This also benefits the RS4’s 0-100km/h sprint time, which falls two tenths to 3.9 seconds in Competition Plus guise. 

The V6 breathes a little easier, too, with a different exhaust. Audi says the extra sound is down to 8.0kg less sound deadening in the car.

There’s more resonance at idle that does feel tiring sitting in traffic idling but the trade-off is a brawny mid-range baritone that develops into a shrill bark approaching the redline.

One of the biggest benefits of the Australian market waiting this long for VW’s ID. range is the upgraded battery and charging offering.

The ID.5 GTX has a larger battery than the ID.4, measuring 84kWh which helps off-set its slightly less efficient all-wheel drive system. The result is a WLTP driving range of 522km between charges, which is only 22km less than the ID.4. It’s still plentiful, and on the higher end at this price point.

Additionally, the charging specs are great. A peak speed of 175kW on DC means a charge time of around 22 minutes (10 - 80 per cent) on a pylon capable of outputting such a speed, while on AC it is 11kW, making it worthwhile plugging in down at the local shops.

The big missed opportunity here is the lack of vehicle-to-load, vehicle-to-grid or a household power outlet in the cabin or boot. These are convenient features becoming more prevalent in the market. At least VW throws in a wall socket and a Type 2-to-Type 2 charging cable as standard.

The Audi RS4 wagon is rated to use 9.5L/100km in ADR combined cycle (urban/extra-urban) consumption testing while the slipperier RS5 returns 9.4L/100km in the same test. 

We weren’t able to run accurate or particularly relevant fuel figures on the event but the trip computers showed around 12L/100km in both RS4 and RS5. 

While these numbers are high compared to your average passenger car, the Audi is more efficient than BMW's rivals, and gets remarkably close to the hybrid C63 in the real world.

The fuel tank is quite small for this kind of vehicle at 58 litres. That limits the RS4’s theoretical driving range to 611km. 

Unsurprisingly, the Audi RS4 and RS5 require 98 RON premium unleaded petrol. 

The ID.5 GTX isn’t quite in the same vein as other ‘performance’ EVs. It feels more measured than a Tesla Model Y Performance for example. But then it also feels a lot more organic. It feels a lot more like a car.

This is because rather than focus on straight-line performance, the GTX has benefits when it comes to its handling. Compared to the ID.4, for example, the ID.5 is sharper on its front axle, adding a little additional torque at the front to make it sharper and faster to grab the tarmac.

Its accelerator response may be comparatively steady, but somehow the ID.5’s more traditional stability control tuning allows it to have a bit more leeway when you push it in the corners. It grants it a little extra fun factor, where some rivals are too locked down.

Additionally, VW’s experience in providing a balanced ride and sharp steering tune is on full show. While a lot of electric vehicles in this class feel a little over-electrically assisted or even vague when it comes to the steering, the ID.5 feels connected and accurate.

The adjustable ride settings are also a rare win for an electric mid-sizer. This is because you can adjust the ride to suit the conditions. If you’re on a bumpy suburban road for example, you can keep it nice and soft. But if you’re out carving corners in the countryside, a much firmer setting is available to help limit the amount of floaty rebound this car’s low-set battery weight can have.

It does adjust in a limited band, so there’s still a bit of softness to it, which combines with the predominantly rear-drive characteristics to make for a distinctly different vehicle to a Tiguan, for example.

It’s simply not as athletic as VW’s finely-tuned combustion offerings, but then its more plush open-road feel isn’t necessarily worse. At the very least it maintains all those key refinement characteristics which make Volkswagens generally a cut above to drive.

The time allocated to driving the RS4 Avant Competition Plus was fairly limited and we were sadly unable to sample how the highly adjustable coil over suspension performed where it makes most sense — on the racetrack. 

Still, winding country roads between Sydney and the Southern Highlands served up some challenges, demonstrating how the Competition Plus pack changes the character of the RS4 and RS5. 

The only real negative is comfort, specifically over those horrible plastic speed bumps that litter shopping centre car parks. With adaptive dampers, carmakers can set programs for these kinds of obstacles to soften and stiffen the clever shocks at just the right time. Not so the Competition Plus pack cars, which ride these bumps harshly.

That about does it, though, and everything thing else is a net benefit. The steering system addresses some criticism of the earlier RS4s. Further than a retune, the Competition Plus gets a new rack, that is non-progressive with a fixed ratio of 15:1 (instead of 13.3:1) and 2.4 turns lock-to-lock. The reactions to each input feel a hint more faithful. 

When above 40km/h the coil overs come into their own. Even though the RS4 rides firmly it doesn’t constantly jiggle over small bumps. Over sharp-edged hits, the suspension rounds the hits off so, while you feel them, there’s a sense of control and sophistication. 

Having speed limits to contend with means it is essentially impossible to find the limits of grip of the 275/30R20 Continental SportContact 6 tyres on the road and there isn’t much body roll, either.

The RS4 is still rewarding, though, getting up on its toes just enough through a series of bends to feel engaging. It gives an impression of being quite light and at 1820kg it is now considered featherweight next to rivals.

The RS4's Quattro all-wheel drive system favours the rear wheels when driving normally (60 per cent rear) and can send up to 85 per cent of the drive to the back axle. 

The tweaked electronically-controlled rear limited-slip differential amplifies the throttle steer-ability of the RS4, giving you the confidence to squeeze the gas on exit. 

It helps that the Competition Plus bucket seats are a little thinner and set closer to the floor giving you more feedback. This is the key differentiator between the RS4 and RS5 we drove — the buckets make the car feel alive. 

Strong brakes are made up of 375mm front rotors clamped by six-piston calipers. Optional carbon ceramic brakes with larger 400mm front rotors help save 6.5kg and, if you plan to use the RS4 on track, are a smart buy along with a set of Pirelli P Zero Corsa semi slick tyres ($850). 

Really, though, neither the RS4 nor RS5 are the perfect car for the track. They are plenty capable and fast on the road with just enough fun, reward and character thrown in to keep you coming back for more.

The Audi A4 range was rated a maximum five stars in ANCAP safety testing in 2021, with the rating now considered expired. The stamp also only applied to four-cylinder models — so not the RS4 we drove. 

It has lots of safety equipment, including eight airbags (dual frontal, side chest, front and rear side head curtains), autonomous emergency braking (AEB) functional up to 250km/h with pedestrian detection, front and rear cross-traffic alert, lane-keep assist, blind-spot monitoring, safe exist warning and tyre pressure monitoring.

Adaptive cruise control with lane-trace assist makes it an easy car to use on the motorway. The systems are well integrated and easy to switch on and off as you like. 

VW hasn’t used this opportunity to increase its standard warranty terms of five years and unlimited kilometres, however, the battery pack is covered by an industry standard eight-year/160,000km deal. 

There are other ownership perks designed to coax people into an electric car, though. Servicing, for example, is only required once every 24 months or 30,000km and when packaged up at the time of purchase, very affordable.

A 10 year or 150,000km plan costs $2890, or just $289 a year, which is excellent for a European car, and is even more affordable than some of its Korean and Chinese rivals with generally longer service intervals.

On top of this, VW stresses the repairability of its battery components, and promises parts supply will continue for 10 years after the discontinuation of the ID.4 and ID.5 range in its current form, with repairability through its network for at least 15 years.

Audi covers the RS4 and RS5 with a five-year/unlimited kilometre warranty which is now the expected norm across the premium part of the market. 

A five-year service plan can be pre-purchased, costing $3630 for both models with maintenance due annually or every 15,000km. 

After the five-year warranty period, owners can choose to extend the service packaging and warranty for two extra years at a cost of $4260. This can be done twice, extending the warranty up to nine years.
