What's the difference?
It's the end of the line for that Audi A4 as we know it. In saying goodbye to the ‘B9’ generation A4 that launched in 2015, we welcome the Audi RS4 Competition Plus.
It is the most hardcore example of the breed yet, sitting lower to the floor with hard-edged gear changes, lightweight wheels and snuggly bucket seats. You can also get it in swoopy RS5 Sportback guise.
Audi is only bringing 75 units of each down under as a swan song for the B9 generation RS4 and RS5 before the even-numbered model moves into its all-electric future.
As we’ll go on to discover, these two special models see the A4 and A5 bow out in style.
The Audi Q5 now has a sportier-looking sibling, with the German brand's all-time best-selling SUV welcoming a sleeker, more aggressive solution it calls its Sportback range.
And look, spoiler alert, it looks better than the regular Q5. It's as simple as that. So if that's all you're here to find out, feel free to close the laptop, put the phone away, and move on with your day.
But you'd be doing yourself a disservice, because there are more questions to be answered here. Like will you paying in on-board comfort for this new raked roofline? Do the Sportback's sporty intentions make for a more annoying daily drive? And how much does Audi want you to pay for one?
All these questions and more answered. So stay with me.
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.
Note: CarsGuide attended this event as a guest of the manufacturer, with accommodation and meals provided.
Let’s forget the money, for a second, because yes, you’re paying more for the Sportback variant. But if you can afford it, then why wouldn’t you. This is a sleeker, sportier and more stylish answer to the regular Q5, which was already a super-solid offering in the segment. And as far as I can tell, the practicality sacrifices you have to make are minimal at best.
So why not?
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.
Our adventure began with the SQ5, and, to my eye at least, it looks mean, and more like a jacked-up hot hatch than sportier version of a mid-size SUV.
Speaking of which, it looks bigger than a mid-size, too, as though the flattened roof has pushed the rear out for more length, at least visually.
By far its best angle, though, will be afforded to the people in front of you on the road, with each peek in the rear-view mirror revealing a wide, forward-leaning grille, all black honeycomb mesh, with a cat-clawed bonnet and headlights that sweep back into the bodywork, hinting at speed before it even sets off.
Side on, the massive 21-inch alloys hide red brake calipers, but it does also reveals a tale of two SUVs, with the front half looking taller and straighter, while the rear roofline is more raked as it flies towards a fairly small rear windscreen with a roof spoiler that juts out over it.
At the rear, the quad exhaust tips (which sound great), and a boot spoiler moulded into the bodywork complete the package.
But even in lesser lesser Q5 45 TFSI guise, this Sportback looks the business, I reckon. Though a little more premium than performance-focused, perhaps.
As the name suggests, the Sportback version gives you, well, a sportier back, and it all starts at the B-Pillar, with a more raked roofline that gives this version of the Q5 a sleeker, more slippery look.
But they aren’t the only changes. In Sportback models, the single-frame grille upfront is different, and the grille is also positioned lower, and seems to jut out from the bonnet more, for a lower, more aggressive look. The lights are also positioned a little higher, and those massive air vents on either side are different, too.
The cabin is the usual level of Audi niceness, with a big central screen, big digital screen in front of the steering wheel, and a sense of genuine solidity and quality wherever you look.
There are some questionable materials at work, though, like the door trims and the hard plastic that your knee rubs against when driving, but all in all, it's quite a lovely place to spend time.
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.
The Q5 Sportback range stretches 4689mm in length, 1893mm in width, and around 1660mm in height, depending on the variant. It rides on a 2824mm wheelbase.
And remember when I said there were few practicality penalties for the new sportier look? This is what I meant.
Up front, it's basically the same Q5, so if you know that car, you'll know this one, with its spacious and airy feeling front seats.
In the back, though, things are a little different, just not quite as different as I was expecting. The new sloping roofline has actually only reduced headroom by 16mm. I’m 175cm tall, and there was clear air between my head and the roof, and plenty of leg-room, too.
The central tunnel arrangement means you probably don’t want to squeeze three adults across the back, but two would really be no problem at all. That way, you can deploy the back seat divider to uncover two cupholders, use the two USB charge ports or adjust your climate controls, including temperature settings.
In the 45 TFSI and SQ5 models, the rear seats also slide or recline, meaning you can prioritise luggage space or passenger comfort, depending on what you're carrying.
Up front, there’s heaps of little cubby spots, including a key storage spot under the aircon controls, another in front of the gear shift, a phone slot next to the gear shift, two cupholders in the big centre console, and a surprisingly shallow centre console that’s home to a wireless phone charger and a USB port, joining the regular USB port under the drive mode selector.
And at the rear, Audi reckons there’s 500 litres of storage, only about 10 litres less than the regular Q5, which grows to 1470 litres with the second-row folded.
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 three-model line-up (two regular Q5s and the SQ5) Sportback range kicks off with the Q5 40 Sportback TDI quattro, which will set you back $77,700 (which is plenty more than the $69,900 of the regular Q5).
The entry-level Q5 Sportback gets 20-inch alloys, a standard S Line sporty exterior styling treatment, LED headlights and tail lights, and an electric tailgate with gesture control. Inside, there’s leather trim, electric sport seats, three-zone climate, paddle-shifters for the steering wheel and ambient interior lighting.
You also get the virtual cockpit, the 10.1-inch central screen with all the Connect Plus services, like live traffic, weather and restaurant tips, as well Android Auto and wireless Apple CarPlay.
The range then steps up to the Q5 45 Sportback TFSI quattro, yours for $86,300. That's another marked jump from its regular Q5 equivalent.
That model delivers a new 20-inch alloy wheel design, a panoramic sunroof, and Matrix LED headlights, The S Line treatment extends to the interior, along with Nappa leather trim, heated front seats and a sliding or reclining rear bench. You get a better sound system, too, with 10 speakers, including a sub-woofer.
Finally, the SQ5 Sportback is yours for $110,900 (up from $106,500), and delivers 21-inch alloys, adaptive dampers and red brake callipers, while inside you get electric steering adjustments, a head-up display, colour ambient lighting and a banging Bang and Olufsen stereo with 19 speakers.
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.
There are three engines total here, kicking off with the 2.0-litre TDI in the Q5 Sportback 40. It produces 150kW and 400Nm - enough for a sprint to 100km/h in 7.6s. The 2.0-litre TFSI in the Q5 Sportback 45 petrol bumps those figures to 183kW and 370Nm, lowering your spring to 6.3s.
Both pair with a seven-speed S tiptronic automatic, and feature a 12-volt mild-hybrid system to smooth out acceleration and lower fuel use, as well Quattro ultra, which can disconnect the rear drive shaft so only the front wheels are driven.
The SQ5 gets a seriously lusty 3.0-litre TDI V6 which deliver 251kW and 700Nm, and a sprint of 5.1s It also gets a 48-volt mild-hybrid system, and an eight-speed tiptronic transmission.
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.
All Q5 Sportback models are fitted with a 70-litre fuel tank, which should produce a driving range in excess of 1000kms - though prepare for pain at the pump. Sometimes premium fuel in Sydney can run to around $1,90 a litre, for example, so the good stuff will cost you around $130 bucks a tank in the petrol cars.
Audi says the Q5 Sportback 40 TDI will sip 5.4 litres per 100km on the combined cycle, while emitting 142g/km of c02. The 45 TFSI needs 8.0 litres per 100km on the combined cycle, and will emit 183g/km of c02. The SQ5 sits somewhere in the middle, with 7.1 litres per 100km and 186g/km of c02.
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.
How to best describe the drive experience in the Q5 Sportback? That's easy. And it's 'easy'.
Honestly, I know this is ostensibly the sportier version of the Q5, but the truth is that, in the 45 TFSI version we tested, it's a comfortable, light-feeling drive experience that only ever reveals its sporty nature when you really command it to.
Left in its Auto drive mode, the Q5 45 TFSI will positively waft around town, road noise kept to an absolute minimum, and feeling somehow smaller and lighter than its dimension would suggest.
You can dial-up the aggression by cycling through the drive modes, of course, but even in Dynamic guise it never feels too harsh, too aggressive. More that you've simply tightened the screws a little bit.
Plant your right foot and the 45 TFSI will collect speed in a way that Audi refers to as "hot hatch-like", punching towards the 100km/h sprint with verve and aggression. But having just stepped out of the SQ5, it still feels somehow sedate, and almost relaxing, rather than out-and-out aggressive.
And that's because the SQ5 variant is clearly, purposefully, the performance-focused variant here. I think this V6 engine is an absolute peach, and its the kind of powerplant that inspires you to stick with the vehicle's most dynamic settings, putting up with the just-too-firm suspension settings so you can access more fo the grunt more quickly.
And it feels constantly ready for action. Tap the accelerator and the car bristles, dropping down a gear, revving higher and preparing for your next command.
Through bends, it feels smaller and lighter than you might expect, with plenty of grip and steering that, while not overflowing with feedback, feels true and direct.
Short answer? It's the one I'd take. But you'll pay for it.
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 Audi Q5 Sportback carries a five-star ANCAP safety rating thanks to the regular Q5, but that’s really the minimum cost of entry these days. So what else do you get?
Advanced driver-assist systems on offer here include autonomous emergency braking (with pedestrian detection), active lane-keep assist with lane change warning, driver attention assist, blind-spot monitoring, rear cross-traffic alert, park assist, a great surround-view camera, parking sensors, exit warning and tyre pressure monitoring, and more radars than you can poke a stick at.
There's also twin ISOFIX anchor points, and top-tether points for child seats.
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.
All Audis are covered by a three-year, unlimited-kilometre warranty, which really isn’t great in a world of five-, seven- and even 10-year warranties.
The brand will let you prepay your services, required annually, for the first five years, with the regular Q5 Sportback billed at $3140 and the SQ5 billed at $3170.
