Audi RS4 vs MG MG4 Urban

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.

The MG4 Urban is not only the right car at the right time, perfectly catering to buyers looking to avoid rising petrol prices, it’s also a welcome return-to-form for MG as a brand.

MG is seemingly at its best when it sticks to small cars. It has traditionally excelled with the MG3 and ZS, smaller, more affordable products that keep expectations in check and can win over customers looking for the best bang-for-their-buck rather than simply the best car.

That’s not to say the MG4 Urban isn’t a good car. It offers tremendous value for money, excellent interior space and drives nicely, so anyone who has been considering making the switch to an EV should seriously consider this new arrival.

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.

MG says the design inspiration for the MG4 Urban came from the $100,000 Cyberster. While there are certainly a lot of differences between that roadster and this hatchback, the air-intakes and wheel design are indeed very similar. And I guess the badge is the same too, so there’s that…

But, comparing it to the Cyberster misses the point. What makes the MG4 Urban’s design more interesting is the bits you can’t see. While it shares the same name as the MG4 Hatch, this car has almost nothing in common with it. That’s because this new MG4 Urban is based on the brand’s newer EV underpinnings that debuted on the MGS5 EV.

That means the MG4 Urban is front-wheel drive, whereas the hatch is rear-wheel drive, and because of the way the battery is integrated into the chassis, it creates not only a bigger hatchback but also one with a different shape.

The Urban is more ‘cab forward’ (to use design parlance) meaning a shorter bonnet, which creates more cabin room. It also means there is more boot space because the powertrain is located up front.

MG does a good job with cabin presentation too. It’s another step forward for the brand, improving the overall level of fit and finish from its earlier models, to create a cabin that looks modern and doesn’t feel like it has been built to a price.

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.

As I just mentioned, the cabin is bigger than the other MG4, which creates good space in both seating rows. 

Up front they’ve placed the gear selector on the steering column to create space for more storage in the centre of the car. That means there’s plenty of shelves, cubbies and cup holders to take care of your small (and not so small) items, spread across the cabin.

As for the boot, the switch to a front motor and a smaller rear suspension means a 382-litre boot with all seats up and 1266L if you drop the back seats. Plus there’s a 98L underfloor storage spot, in place of a spare wheel (with a puncture repair kit included instead).

The design of the key controls are simple and easy to use, with a digital display for the instruments ahead of the driver and a 12.8-inch multimedia screen in the centre of the dashboard.

Navigating the menus is relatively straightforward but in a victory for user-friendliness, MG has listened to feedback (and incoming Chinese government regulations) and added some physical controls. There are buttons and a dial for the air-conditioning system and a volume knob for the sound system.

MG made its reputation in Australia by selling some of the most-affordable models on the market, filling the hole left by mainstream brands like Toyota, Hyundai and Mazda as they increased the entry-level prices in their respective line-ups. Something MG itself tried with the HS, QS and U9, as it expanded beyond the once-popular MG3, MG5 and ZS.

The MG4 Urban is a return to form in that sense for MG, with this new small car starting at just $31,990 drive-away. For context, the MG4 Hatch starts at $37,990 drive-away, so this is a much cheaper proposition. That starting price is for the MG4 Urban Standard Range, the Extended Range variant is priced from $34,990 drive-away.

That pricing does not feel accidental from MG Australia, despite what they may suggest when pressed. That’s because the new BYD Atto 2, the direct rival to the Urban, starts at $31,990 plus on-road costs. Even so, BYD has the last laugh, because it offers both the BYD Atto 1, which starts at $23,990, and the Dolphin, which is priced from $29,990 - to undercut the MG4 Urban, even if neither are considered direct competitors.

In terms of specification, both the Standard Range and Extended Range have the same equipment with the exception of the obvious - a bigger battery, and more power from the motor.

Standard equipment highlights include 17-inch alloy wheels, LED headlights and tail-lights, a leather-wrapped steering wheel, PVC seat upholstery, heated front seats, Bluetooth connectivity with wireless Apple CarPlay and Android Auto, in-built navigation and a six-speaker stereo.

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 MG4 Urban Standard Range is powered by a 110kW/250Nm electric motor that drives the front-wheels via a single-speed transmission. The Extended Range has slightly more performance, 118kW and 250Nm, but aside from that they are the same motor.

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 biggest difference between the two MG4 Urban variants is the battery. The Standard Range has a 43kWh battery good for 316km of driving between charging, while the Extended Range gets a bigger 54kWh battery to make it capable of up to 405km.

We didn’t drive the car long enough to get a clear indication of real-world efficiency and range, but it performed well during our drive in suburban Sydney. The steady stop-start traffic gave the battery its best chance to perform well and the early indications are its range is close to claim, at least under the right circumstances. We’ll have to reserve definitive judgement until we’ve had a longer test drive.

What MG was very keen to highlight are the cost savings of buying an EV at a time of sky-high petrol prices. The company made a point that using off-peak electricity, which can be had for just 6c per kW from certain providers, means you can replenish the battery of the MG4 Urban Standard for just $3.44. 

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.

What really stood out about the MG4 Hatch is its rear-motor, rear-wheel-drive layout, which made it a very dynamic and almost sporty car. In my 2023 review I called it “a genuinely enjoyable small car to drive".

The MG4 Urban doesn’t quite leave the same impression. Again, we had only a brief and (appropriately) urban test drive around Sydney’s beachside suburbs, but the MG4 Urban proved competent rather than commendable.

But, let’s be honest, unless you’re looking for driving thrills in the wrong place (affordable, city-focused hatchbacks) the MG4 Urban does the job it is required to do. It’s as nice as any other mainstream hatch to drive from Point A to Point B.

The ride could be a little softer and more compliant, with the suspension feeling too firm at times, but with its electric motor it’s a quiet and relaxed driving experience. The electric motor provides adequate performance too, certainly more torque in less time than you’ll get in a petrol-powered hatch.

Curiously, MG Australia executives said the MG4 Urban was locally evaluated and tuned but could only offer a vague mention of ‘holistic’ changes to better suit it to local conditions, rather than pointing to any specific Australia-developed changes to the suspension, steering or powertrain.

It may be small and cheap, but that doesn’t mean MG has cut corners on safety. The MG4 Urban comes equipped with the MG Pilot and a suite of active safety features, including adaptive cruise control, autonomous emergency braking, lane keep assist, blind spot monitoring, driver attention monitoring and speed limit notification.

The latter two are the most evident, as they provide a steady soundtrack of beeps as you drive along. Take your eyes off the road for more than a few seconds as the driver attention system fires up, while the speed sign recognition gets busy in Australia’s ever-changing speed limits.

While MG has undoubtedly improved the sensitivity of some of these systems compared to other models, they are still more active than rival products. Perhaps more concerning, the speed limit recognition repeatedly beeped to tell me I was in a ‘25km/h’ zone, which is simply not a recognised speed limit on Sydney roads.

Like so many other brands, MG needs to further refine these active safety systems in order to make the driving experience more relaxed and less distracting.

MG says the MG4 Urban has secured a five-star rating from Euro NCAP, which is expected to be carried over by ANCAP. 

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 MG4 Urban is covered by the brand’s 10-year/250,000km warranty, as long as you service it at an official MG service centre. If you don’t get your car serviced with the company directly, your warranty reverts to seven-year/unlimited km coverage.

Servicing intervals are every 12 months or 25,000km and will cost you $1366 over the first five years. The cheapest visit is just $149 but the major service, after four years, is a pricey $472, which does push against the idea that EVs are cheaper to service due to less moving parts.
