Audi RS4 vs Mini Aceman

What's the difference?

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.

In many ways - range, performance and purchase price, for instance - the Mini Aceman is decent value, somewhat par for the course and would give its logical competition a proper marketplace run. But it’s better than that. The car’s big point of difference is its retro charm and the fact that it’s been tuned to be a fun drive rather than the non-confronting experience some carmakers strive for.

The performance is strong and the handling and steering serve up a bit of entertainment as well as giving the car a particular flavour. Which, as electric drivelines threaten to homogenise cars even further, must count for something.

Yes, some of what you’re paying goes towards that arguably nebulous notion of 'driving-spice' but once you’ve driven it, you’ll probably know what we’re talking about. A new car purchase is always special, so why not make that specialness last a bit longer with a car that will still be an entertainer long after the showroom thrill has worn off.

Meantime, it’s easy to see why Mini has already begun to run-out stocks of the cheaper E model. The SE still manages to play on that cheeky charm, but offers a more mature vehicle into the bargain. Not a bad trick, really.

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.

Though vaguely retro on the outside, the real nostalgia hit comes when you step inside the Aceman.

The huge, round central display that’s been associated with the Mini brand since day one, returns, but this time in 240mm, OLED screen form.

The display is also where you get to choose how the instrumentation and information looks, with configurable display incorporating a total of eight modes that alter the colours, sounds and visuals of the screen. Is it cool? Er, yes, actually.

There’s also the Mini personal assistant at your service to crank up the heat when you’re cold and switch on the air conditioning when you’re not (all voice activated) and the personal assistant can also learn stuff such as knowing particular navigation co-ordinates mean you’re at the entrance to an underground car-park, at which point the car will wind down the driver’s window so you can flash your credit card. If you think about it too hard, that’s going to be more creepy than cool for some of us.

The move to electrification, of course, is environmentally driven, so the Aceman’s ethos leans into that, too. There is, for example, a complete absence of leather or chrome, the alloy wheels contain as much as 70 per cent recycled material and are produced with renewable energy.

The floor mats, floor structure and interior surfaces are made from at least 90 per cent recycled polyester, and Mini claims a 98 per cent reduction in greenhouse gases compared with the same stuff made from leather.

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.

Perhaps it’s the packaging designed to play the retro card, but I can’t help feeling the door openings on this car are pretty tight. The rear doors, in particular, seem designed for someone smaller than I, and even once I’m in the news doesn’t really improve.

The Aceman’s rear pew seems tight for both foot and legroom and should you have an adult in the back seat, they’re only going to fit by having somebody smaller in the front seats. The chances of a six-footer (183cm) sitting behind a driver of similar stature are pretty slim (over a distance, anyway).

This is all to do with Mini keeping the overall length of the car to just over four metres, and stuffing a compact SUV into that space.

Perhaps that also explains the giant blind spot formed by the thick B-pillar. Either way, taller drivers will find themselves peering around it when crossing or tuning into intersections.

The seats themselves, however, are quite charming. They look a bit small with their cloth trim, but in reality, they’re comfy and supportive. The pleated John Cooper Works front seats that are standard in the SE are phenomenally good. The only thing missing is that distinct smell of leather we’d normally associate with a 60-grand car.

The traditional row of toggle switches under the central screen remains… sort of. These days, they’ve been modified to act as the starter button for the keyless start system and also the gear selector. The problem is that they’re gloss black on a black background, so they can seem a bit indistinct.

The gear selector has also been reinvented – again – with a separate Park button now to the side of the toggle. The other ergonomic glitch I noticed was every time I went for the interior door handle to leave the car, I fumbled for a second till I located it, tucked up under the armrest.

The clean, uncluttered dashboard means a couple of items have moved to the space between the front seats. So, there’s a pair of cupholders, a small, lidded compartments and a pair of USB charge-points all living in the real estate between the front chairs. That’s in the SE, anyway, because the cheaper E retains only the cupholders.

The luggage space is deeper than a lot of EVs manage and the rear seat folds 60/40 to open up a huge area if you don’t need the seats. With the rear seat up, there’s 300 litres of capacity and, with the seat folded, that leaps to 1005 litres.

There are three child restraint tether points, and the luggage space is served by a 12 volt socket.

There’s also a luggage cover that can be quickly removed for taller items. The tailgate is manually operated.

There are also three ISOFIX attachment points for child seats; two on the rear seat and one on the front passenger seat.

Like the electric Mini Cooper launched last year, the Aceman is available in two versions with some important technical differences beyond the usual trim and equipment stuff most carmakers rely on to locate their models on the price totem.

The E (Electric) model is the most affordable five-door Mini EV with a price-tag if $51,990, driveaway. For that you get plenty of kit including adaptive cruise control, augmented reality navigation, heated front sports seats, a panoramic sunroof, sports steering wheel, 100-watt stereo and a cabin with splashes of nostalgia and piano black in equal measures.

There are also 19-inch alloy wheels and two-tone paint which teams a metallic body colour with a black roof. Wireless Apple CarPlay and Android Auto are included, too. So is dual-zone climate control, keyless entry and start, digital radio and folding exterior mirrors

The SE (Sports Electric) gets a different 19-inch alloy wheel, and adds an extra exterior colour as well as the lovely John Cooper Works front seats with electric adjustment, tinted glass, silver interior highlights, a Harman Kardon stereo upgrade and a different trim grade for the upholstery. All yours for $60,990 which sounds like quite a bit of extra money for those add-ons.

Until, that is, you realise the SE also packs a bigger punch with a bigger battery for more range and a perkier motor for better performance. Ah, so that’s where the money goes.

The catch is the E model is not long for the Australian market (I have never, till now, been invited to the launch of a car that was already in run-out). Local customers have voted with their feet and told Mini the more expensive SE is the one they want for a variety of reasons.

So, the E will continue to be sold here until stocks run out, probably around the end of 2025. And for that reason, the model we’ve driven here is the SE.

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.

Things kick off the with the E model’s 135kW electric motor that also produces 290Nm of torque. That, says Mini, is enough to get it from rest to 100km/h in just under eight seconds. The motor is powered by a 38.5kWh battery living under the floor

The SE gets more battery and more power; 49.2kWh and 160kW, respectively, with 330Nm of torque on tap as well. The claimed 0-100km/h time falls almost a second to 7.1sec.

A single-speed reduction transmission is fitted and the electric motor in both models is a single one, driving the front wheels in true Mini tradition.

Of course, the other aspect of a Mini’s driving experience is its go-kart handling. To that end, the Mini EV is tuned for handling and response and features a MacPherson strut front end and a multi-link suspension arrangement at the rear. Potentially offsetting that sidestep, however, is the car’s heft which, at 1.6 tonnes, is very un-Mini.

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. 

Mini claims a power consumption figure of 14kWh per 100km for the E and 14.4 for the SE. Theoretically, that should give the E a (WLPT) range of 310km and the SE a claimed maximum of 406km.

In reality, you’ll be looking for a power-point before that, because those are both maximum range projections and, in highway conditions, without the regeneration potential of suburban running, you’ll use more power per 100km travelled.

Both version of the Mini EV can use fast chargers, the E model capable of 75kW DC charging, and the SE’s bigger battery able to handle 95kW. Charging at home on an 11kW AC outlet is also possible but, obviously, takes a lot longer to reach full charge.

For DC charging, the Mini uses a CCS Type 2 charging plug.

Speaking of which, on that 75kW fast charger, the E’s battery will go from 10 to 80 per cent charged in 28 minutes, while the bigger battery in the SE will take 31 minutes, its faster charging offset by its larger battery capacity.

At 11kW AC, the Aceman E can go from discharged to fully charged in four hours, 15 minutes, while the SE will take five-and-a-half hours.

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.

Much is made by Mini of its tradition of go-kart-like handling. And fair enough, it’s one of the things that allows the Mini brand to justify a premium price-point. And the good news is that this version, electric driveline notwithstanding, continues that theme. Position the manually-adjustable steering column to the right spot and suddenly, you’re in a car that encourages you to enjoy the drive.

The steering is light but accurate and is actually one of the better calibrated modern, electrically-assisted set-ups we’ve sampled for a while.

The only thing it doesn’t do is give the feeling that you’re sitting right over the physical point in the car that it rotates around when it corners.

Instead, you get the impression of there being a fair bit of Mini nose jutting out in front of you, with the driver’s seat positioned well back in the cabin.

Given the extra length of the five-door layout, that’s not completely unexpected, but it’s something drivers of short-wheelbase Minis will perhaps note.

What that doesn’t affect is the way the car feels tied down pretty well, but never degenerates into a crashing, buck-board. Despite the flat cornering, there’s always some suspension travel left, it seems, and the damping is clearly spot on as it arrests wheel movement without interfering with the fun.

There’s plenty of grip, too, and if you play the Mini game and hustle it through a few corners, the Aceman quickly reveals its fun side, which is precisely the point here.

The instant urge of an electric drivetrain is also very much in evidence and flooring the throttle pedal results in an instant surge of Newton-metres. I could do without the Warner Brothers soundtrack (and I did, by turning it off) but the acceleration itself is pretty impressive without being confronting (as some EVs with their brutal delivery can feel).

The only other thing we’d comment on is a level of tyre and road noise that is far from best in class. Okay, so a bit of tyre roar is okay, and it’s only audible at all because silence from traditional mechanical sources is such an EV thing.

Driver assistance packages abound in the Aceman, starting with adaptive cruise-control, parking assistance, rain sensing wipers and auto headlights, lane-keeping assistance, tyre pressure monitoring and a driver-attention monitor.

There’s autonomous emergency braking that works from 5.0km/h up and can detect cyclists and pedestrians. There’s also blind-spot monitoring, cornering brake control, stability control, rear collision prevention and rear cross-traffic alert and braking.

Inside, you’ll find front, side and head airbags as well as a centre airbag to prevent head clashes in the case of a side impact. There’s also a surround view camera system and rain-sensing wipers.

The Mini Aceman hasn’t been locally crash tested, but other variants of the same platform have been tested in Europe according to Euro NCAP protocols, in which they scored the full five stars for safety.

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.

The Mini factory warranty was extended a couple of years ago to five years/unlimited kilometres. That’s an improvement on the three years the brand previously covered, but it’s still well short of the seven, eight and even 10 years of some competitors. In the fully electric Aceman’s case, there’s also eight years/160,000km worth of cover for the high-voltage battery. There’s also five years of roadside assistance thrown in.

There are no set service intervals for the Aceman, Mini instead preferring to use the concept of condition based servicing which involves the car telling you when its ready for maintenance. There’s capped price servicing available which costs $1371 for the first four years.

Beyond that, running costs will depend heavily on where and how your charge the car. Charging at home form a solar array will be the cheapest, while using commercial fast-chargers will inevitably ratchet up your running costs.
