Porsche Panamera vs Audi RS4

What's the difference?

The Panamera is the ‘have your Porsche and drive it too’ model.

It encompasses the fun of the 911 while still being a comfortable daily driver that can easily fit a family of four. The cabin is sumptuously styled and not hurting for features, either.

Could the ownership costs and storage be better? Probably, but if you’re looking at this model, those items will probably be lower priorities for you.

For my little family of three, the base model Panamera is a win.

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.

This is more than just a new Panamera - it’s a new generation Panamera.

The outgoing model was sort of a mix between the 911 and Macan but didn’t really hit the mark with any of its borrowed elements.

Beauty is in the eye of the beholder but the redesign sees this model get an outward appearance that looks far more aggressive with a distinct profile that now sets it apart for all of the right reasons.

On the outside, the biggest changes include larger matrix LED headlights and a new front fascia that sits a bit higher with more pronounced curving in the bonnet.

The front gets extra air intakes but there are also larger 'air blade' vents behind the front wheel arches which help smooth the air flow around the wheels and add some extra sculpted sportiness to the car's sides.

The rear has been reshaped to look more like the 911 and isn't as pillowy as the outgoing model. There is a new long LED strip light running the width of the rear and an extra brake light for added dazzlement at night. The rear window now spreads to the width of the liftback lid which makes it appear frameless.

The optioned 21-inch alloy wheels look gorgeous in their painted bronze (or Neodyme) glory and feature the Porsche crest in full colour for added pizzazz. The bronze accent is also carried across to the quad exhausts.

All these factors make the exterior design look more cohesive than the previous model.

The interior has been reworked, too, and the dashboard now sports upgraded tech panels that makes the cabin feel cinematic. The optioned passenger display screen only adds to this effect.

Purists will pout, but like the new 911 the analogue cluster and turn-key operation have died a quiet death. You now get a 12.3-inch digital instrument panel and push-button starter. Plus, the gearshift has been repositioned from the centre console to the dash.

The optioned Sports Chrono and Neodyme accent packages of our test model means the dashboard gets a race clock (superfluous for every day driving but fun to look at) and the door handles, steering wheel and dashboard feature the same bronze highlights.

The only elements that don't look the part are the shiny piano black panels mainly found in the centre console. They're too easily scratched/marked for a car at this price point.

The cabin may not be as flashy as its competitors but it's still sumptuous.

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 cabin feels spacious in both rows and the rear row can comfortably fit those who are above six foot (182cm) with a caveat.

Despite being optioned with the '4+1' seating, don't be fooled; the middle rear seat is nothing more than extra room for the out-boarders as the rear centre console takes up all legroom a middle seater might need. Not even a kid will be happy in the middle for long.

Amenities in both rows are good. The heating/cooling and massage functions on the front seats are great and the four-zone climate control means everyone can get comfortable.

Access to both rows is surprisingly good with doors that open widely but the rear footwell lip is high and the well narrow. So, if you have clunky boots on you may feel clumsy getting into position.

My seven-year old found the doors heavy to open and it took him a while to realise he didn’t have to slam the doors shut thanks to the soft-close feature.

Individual storage is better than you usually get in a sports car but all cubbies still fall on the shallower side. There are four cupholders, four drink bottle holders, a glove box, a middle console and two small net map pockets. There is also a dedicated phone cubby housing the wireless charging pad.

The boot aperture is wide and it’s super easy to reach things in the back thanks to the liftback lid but that sloping roofline means you lose out on height for larger items.

Stack bigger things right behind the back seat if you want to fit them. Capacity is below average compared to its rivals at 460L.

The rear row has a 40/20/40 split to open up storage options and there is a very deep cubby underneath the floor with the tyre compressor/repair kit.

Device charging options are great with a total of four USB-C ports, a wireless charging pad and three 12-volt sockets to choose from.  

The upgraded multimedia system looks fantastic and is user-friendly. The built-in satellite navigation is simple to use and the multimedia system, head-up display and instrument cluster can be highly customised.

The base Panamera model now comes standard with wireless Apple CarPlay and Android Auto. Connecting to the CarPlay is easy and the connection remains seamless.

The optional passenger display panel allows the front passenger to control their climate and seat comfort, see a duplicate of the instrument panel or just watch a movie on a long trip.

The screen has a privacy filter, which means the driver can’t see what’s on it and is thus not a distraction. However, no one in my family bothered to use it.

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 base Panamera doesn’t have a hybrid powertrain like its siblings and sports the 2.9L V6 twin-turbo petrol engine of the outgoing model. But it’s been retuned and now produces 260kW and 500Nm – both figures up from the previous model.

The Sport Chrono Package means the 0-100km/h sprint improves from 5.1-seconds to a tummy-sucking 4.8-seconds and my son gave a whoop of delight whenever we had to get up to speed.

The Panamera has an eight-speed, dual-clutch auto transmission and is the only RWD for the Panamera line-up. It also sports a top speed of 272km/h. So, suffice it to say, the engine has the sports cred you expect from a Porsche.

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 official combined (urban/extra-urban) fuel-cycle consumption figure is 9.5L/100km, which is pretty low for a high-performance vehicle (and a big one at that) but after a lot of open road and urban driving my real-world usage came out at 10.9L/100km.

That's the result after not being skimpy with using the power, either, so it's not as thirsty as you might expect.

When it comes to times between fills, the Panamera might surprise you. Based on the official combined fuel cycle and large 90L fuel tank, expect a theoretical driving range of up to 947km (825km using our on-test figure) – which is a great driving range for a performance vehicle, let alone a family one.

The Porsche Panamera only drinks the best, so while the driving range is great you won't be able to fill 'er up with anything but premium 98 RON unleaded petrol.

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. 

Some people might not understand the obsession or loyalty Porsche owners have towards their cars  but if you’re a fence sitter, get in the Panamera. It will make you understand because after driving one... you'll hear yourself say 'I get it'.

The base model has the goods with the engine outputs to ensure the driving experience remains fun and responsive.

The Panamera is no wild bronco, it's a cool customer. The composure for power delivery is unlike other performance sedans you may have driven. Acceleration is effortless without any twitchiness. You never feel out of control.

The air suspension means you hear the bumps more than you feel them but you still get excellent road feedback as a driver.

Passenger comfort is high, despite the cabin being quite loud with road and engine noise, because the seat and ride comfort remains well-cushioned. Fatigue and jostling are at a minimum.

The handling of the Panamera when it comes to cornering and steering feels dynamic and agile. I made a point of doing multiple mini roadies this week, simply for the joy of driving it.

While the Panamera is the most fun on a winding mountain road, it's a pleasant open-road cruiser as well.

The base Panamera has three driving modes - 'Normal', 'Sport' or 'Sport Plus' with a 20-second power booster available when you need extra oomph.

The Normal mode is sufficient for daily driving and the Sport Plus offers stiffer suspension and handling but the preference is to keep it in Sport mode.

Mainly because in this mode you get an awesome throatiness from the exhaust as well as the dynamics you expect from a sports car.

It’s a bit deceptive but the Panamera is massive and sits at 5052mm long and 2165mm wide - so, it definitely fills out a parking space!

However, the 360-degree view camera system is one of the best in the segment but you may still get choosy with where you park it.

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. 

Porsche offers the Panamera with a three-year/unlimited km warranty, which is less than its competitors. It's more typical to see a five-year/unlimited km warranty in this segment.

Servicing intervals are reasonable at every 12-months or 15,000km, whichever occurs first and pricing varies per dealership.

The one I contacted (in Sydney) confirmed the first four years of servicing costs $8605 for an average of $2151.25 per workshop visit.

Worth noting the fourth year is a biggie at $4875, this major service including everything from an air-conditioning clean and transmission oil change to spark plug check/replacement and safety checks.

The Panamera is up there for service costs, even for the class but this kind of outlay comes with the territory when you're considering a car worth almost $300K. 

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.
