Volkswagen ID. Buzz vs Audi RS4

What's the difference?

The only way to make this car cooler would be to add a split fold-out windscreen and a tube steel luggage rack on the roof.

It’s fast, super practical, comfortable and guaranteed to put a smile on the face of premium family buyers ready to go for something different. And that smile will extend to just about everyone who lays eyes on it. I love it.

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 ID.Buzz GTX is characterised by a unique front bumper with new integrated daytime running lights near its outer edges and a narrower black honeycomb grille. 

GTX badging and the exterior mirror housings are finished in high-gloss black, and 21-inch alloy wheels are standard.

The rich ‘Cherry Red’ solid paint finish of the launch test car is exclusive to the GTX and it’s a fair bet many buyers will stump up the extra $4K required for a two-tone treatment, in this case with ‘Mono Silver’ as the highlight colour.

The interior is familiar ID.Buzz territory, with the long, broad dashtop pushing the windscreen and small front windows beside it into a quintessentially Kombi ‘bay window’-style design.

A 12-inch central multimedia screen sits proud of the multi-layered dash, and a slick 5.3-inch LCD instrument and car data display is fixed in front of the driver.

A black headliner dials up the sporty feel, the electric front seats are a GTX-specific design and the synthetic diamond pattern microfleece trim is highlighted by red contrast stitching and piping. 

The red cross-stitching extends to the steering wheel and smile-inducing stainless steel ‘play’ and ‘pause’ symbols on the accelerator and brake pedals are retained.

The sub-zero cool exterior design manages to merge with a more restrained and practical interior perfectly. VW has solid retro form with the ‘New Beetle’ from the 1990s and this primo ID.Buzz looks amazing. It drew an instant crowd of curious onlookers every time we stopped. 

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.

The ID.Buzz GTX is offered in shorter wheelbase variants with five- and six-seat configurations for other markets, but here it’s seven seats and long-wheelbase only.

At close to five metres long and just under two metres wide, it’s road-trip ready with heaps of breathing room for all seven occupants.

Placement of the gearshift on the right-hand side of the steering column frees up extra space in the front and there’s heaps of storage including a moveable (and removable) centre console unit between the front seats with pull-out drawers at either end, two trays in each door (the lower one offering room for multiple large bottles), a decent glove box and a fold-out dual cupholder unit.

There’s also an oddments shelf in front of the passenger, a wireless device charging slot in the dash and adjustable fold-down armrests on both sides of the front seats.

Pull the handle on the power-opening sliding side doors and the second row opens up with three seating positions offering hectares of room in all directions. 

This row can be moved 200mm longitudinally if a turf war erupts with those in the third row. And storage is great with two pockets and a fold out table on each front seatback as well as huge door bins with waste baskets included. There are also adjustable vents with temperature control in the roof.

There’s enough head and legroom for adults in the third row although the backrest is relatively upright. Even access is straightforward and there are numerous storage trays, cupholders, air vents and storage slots back there.

Power across the cabin runs to two USB-C ports in the dash, another in the front passenger area and four USB-C charging sockets in the rear.

Boot space increases from a handy 306 litres with all seats up to 1340 litres with the 50/50 split-folding third row down, and 2469L with it and the 60/40 split second row lowered. That’s plenty.

And that 1.6-tonne braked trailer towing capacity means a jet ski, even a mid-size camper trailer, is within hauling range.

The power tailgate is welcome and the rear of the boot’s load platform sits above two storage boxes. But you won’t find a spare of any description back there; a repair-inflator kit is your only option. So beware, a flat could really suck the air out of this mobile family room.

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.

The GTX is a twin-motor AWD, the front unit generating 80kW/134Nm and the rear 210kW/560Nm. Total output is 250kW/590Nm which boosts towing capacity from 1.0-tonne in the single-motor ID.Buzz to 1600kg.

A single-speed transmission sends drive primarily to the rear wheels to maximise efficiency, the dual-motor set-up able to direct power to the front axle as required during acceleration or to manage available traction.

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.

The ID.Buzz GTX’s 86kWh lithium-ion battery delivers a claimed (WLTP) range of 473km and the car uses a CCS Type 3 socket. VW includes a Mode 2 and Mode 3 cable as standard.

The claimed 10-80 per cent 200kW DC fast charge time is 26 minutes, while the same top-up takes nine hours at a maximum 11.0kW AC capacity.

Claimed energy consumption on the combined (urban/extra-urban) cycle is 20.2kWh/100km (WLTP) and over several hundred kilometres of mainly B-road and freeway running on the launch we saw an average of 24.5kWh/100km, which isn’t out of order given the type of driving involved.

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. 

Despite the fact that it weighs in at around 2.8 tonnes (2780kg), Volkswagen Australia says this dual-motor ID.Buzz accelerates from 0-100km/h in 6.4 seconds and on to a 160km/h maximum velocity, if you dare. 

And there is always some serious oomph lurking under your right foot. Trundle along at 65km/h, pin the accelerator, and in roughly two blinks of an eye you’re doing 95km/h. 

Proportionally, this car is like a loaf of bread on wheels - about as high as it is wide. And on the windy launch drive we were buffeted a bit, the car moving sideways slightly when hit with a gust. But overall, it remains stable despite its proportions. That said, some wind noise comes over the bluff nose on the freeway, but never to an alarming degree. 

The ID. Buzz rides on VW’s Modular Electric Drive (MEB) platform and there’s been past criticism of the short-wheelbase versions' ride quality, but there are no such issues here.

Suspension is by struts at the front and semi-trailing arms at the rear and this GTX has had a suspension retune with particular attention paid to key components, including the dampers.

On rural roads that have seen better days, dotted with potholes, bumps and thumps, a combination of that suspension retune and the longer wheelbase helped the GTX handle it well. 

There are five drive modes with Comfort the default. Eco smooths out acceleration, tapers the climate control and reduces overall power, while Sport dials up the powertrain, suspension and steering. Traction optimises the AWD system for loose or slippery surfaces and Individual allows you to cherry pick various attributes for a custom set-up.

Steering is progressive rate and you can feel it loading up nicely as you head into a corner. Not the last word in terms of road feel, but the car points accurately and turn-in is nice and progressive.

At the same time you’ve got the electric motors constantly shuffling drive between the front and rear axles, helping you out if you decide to explore the car’s sporty nature and have a crack in the corners.

Tyres are Hankook Ventus S1 Evo3 EV specials (235/45 fr - 265/40 rr) and in long, sweeping bends, taken at pretty decent speed, they grip hard. Even on coarse-chip B-road surfaces there’s a bit of rumble but it’s far from a roar.

Braking is by large (358mm) ventilated discs in the front and, believe it or not, drums at the back. A well-designed, modern drum brake can work effectively and the regenerative braking in an EV like this is a big factor in terms of washing off speed.

In terms of lower speed manoeuvres, you’ve got a 360-degree camera view as well as a reversing camera and front and rear parking sensors. If you really need some help, Park Assist Plus will get the job done for you.

In terms of ergonomics, we spent hours behind the wheel and the front seats remained comfortable and supportive in terms of lateral grip.

Speaking of grip, the steering wheel is nice to hold. And the cool little 5.3-inch instrument and car data display is clear as a bell, and the large 12-inch media screen is easy to use and working through the different screens is largely intuitive.

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. 

The ID.Buzz GTX is covered by Volkswagen Australia’s five-year/unlimited-km warranty with two years’ roadside assistance included. On top of that, there’s an eight-year/160,000km warranty on the drive battery.

That general warranty is in line with the mainstream market, although it’s worth noting an increasing number are stepping up to longer terms, including 10 years.  

There’s a 12-year corrosion perforation warranty and keep servicing with an authorised VW dealer and that roadside assistance support will be rolled over for another two years each time.

The recommended maintenance interval is two years/30,000km. Standard scheduled service pricing is $687 for each of the first five workshop visits, while pre-paid plans covering six, eight or 10 years represent savings of between 30 and 35 per cent on that figure, which is pretty handy.

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.
