2021 Audi RS4 vs 2024 MG MG5

What's the difference?

Practicality, performance and polish, all in one very handsome wagon shape. The Audi RS4 Avant is welcome reminder of the days before SUVs ruled the world, and it leaves you wondering how we ever allowed that take-over to happen at all.

The MG5 works well as a budget-friendly small car, and it’s genuinely good to drive.

Some small let-downs in terms of packaging don’t detract from this car in any major way, but the lack of active safety is a concern considering the features most of its rivals offer.

If it’s on your shopping list, make sure you know what else is on offer in terms of safety before you lock in the MG5 for the savings.

I think it looks fantastic; a tough, low-slung performance wagon that makes you long for the days when SUVs were only for people who wanted to climb mountains, not driveways. 

Looking at it straight-on, the Audi RS4 Avant looks wide and mean, with its blacked-out mesh grille that's kind of folded in the middle, giving it a sharp ridge that juts out in front of it. Interestingly, Audi's Single Frame Grille treatment is now a kind of no-frame grille, with the body colour extending all the way to beginning of the meshing.

Those 20-inch alloys perfectly fill the swollen wheel arches, with the red of the massive brake calipers peeking out from behind the spokes, while at the rear, two massive exhaust exits frame the rear end. 

Inside, it's a blacked-out, leather-wrapped space that feels both tech-savvy and well constructed. There's ridged leather on the seats, and a satisfying chunkiness to both the flat-bottomed steering wheel and the sizeable gear shifter. 

I've heard people complain about the positioning of the 10.1-inch centre screen, perched as it is above the dash a little like an afterthought, but I really don't mind it. Its big, clear, and positioned where it is, easy to both read and reach.

The MG5’s styling might be a little divisive, with the overall shape and look of the small sedan sitting somewhere between its direct rivals, like the Hyundai i30 Sedan, and aspirational models like the Mercedes CLA.

In this Essence variant, the grey insert for the grille gives the front a darker, more aggressive look, though the way the grille mesh weaves makes it look a little like moustache hair.

The large ‘intake-style’ design at the sides gives it a sportier look than its outputs have perhaps earned - not to say the MG5 is sluggish - and following those around to the side of the car leads to a fairly minimalistic and tidy silhouette.

Here, probably most notable is the rather tall gap between the tyres and wheel arches.

The rear, with that sloped-up roofline, transitioning into a gentle lip spoiler, flanked by those lights, is where CLA fans might have the most to say about the MG5’s design.

Notably, the exhaust vents at the bottom are fake. The real exhaust exit is hidden well underneath.

Ah, the practicality of a wagon, remember that? Honestly, I'm sometimes surprised that SUVs have managed such a hostile takeover, especially when I climb out of a well-sorted estate, like the RS4 Avant.

It measures 4782mm in length, 1866mm in width, and 1438mm in height, making it slightly longer - but much lower - than the Audi Q5.

But while Audi's SUV manages a commendable 463L of luggage space with the rear seats in place, the RS4 Avant delivers 495L, with the that number swelling to 1495L with the second row folded flat.

The point is, it delivers the perks of a sizeable SUV, without ever feeling so big. 

Up front, riders will share cupholders, bottle holders in the doors, and multiple USB and power connection point, along with storage cubbies of various sizes and shapes. 

In the back, rear seat riders get the same premium interior treatment as the driver, and get their own air vents with digital climate controls, bottle holders in their doors, USB connection points, and ISOFIX attachment points at each of the window seats in the back. 

Some newer brands to Australia, often MG’s compatriots from China, get some of the ergonomic or tech basics wrong as they focus more on an impactful first impression. Fortunately, MG doesn’t do that, for the most part.

Inside the MG5 is a cabin that looks more expensive than it is, but has some useful features to back it up without the superfluous add-ons.

Aside from the lack of physical climate controls - an annoying cost-saving or interior-tidying trend embraced by brands from budget to bougie - the MG5’s interfaces and ergonomics are pretty sensible.

Accessibility ticks for the steering wheel buttons being few and large enough to use without needing to look, as well as the lack of a panel of buttons and switches in the centre console. Looking at you, BMW.

The screen is also functionally sound, with obvious menu layouts and fairly large buttons as touch points, so it doesn’t feel like trying to operate a tablet while you’re driving.

It does, again, lose points for the climate control situation, which weirdly features a temperature slider as a colour gradient rather than numerical temperatures.

No wireless phone charger means needing space for a plugged-in phone, which the MG5 has just enough of, though similarly ‘just enough’ is the size of the cupholders, which won’t fit a big water bottle.

In the rear, there’s space enough for an adult to sit comfortably behind another adult, though it’s not the place for long journeys.

Strangely, there’s only one central vent control in the rear so only one passenger gets cool air or heat, plus there isn’t a great deal of storage. No armrest or cupholders for rear passengers, either.

Also noteworthy is the single-piece rear seat, which means if longer items need to be transported in the 401-litre boot, the whole rear seat must be folded down and the MG5 temporarily becomes a two-seater.

Under the boot floor is a space-saver spare, though, so bonus points for a more useful addition than a simple repair kit.

MG has managed to cram quite a bit into the MG5 for less than $25K drive-away in its Vibe entry-level variant.

More specifically, you’re forking out $24,990 to head off from the dealership in one, even with its missing active safety features, but we’ll come back to that.

In Vibe specification, the MG5 comes with 16-inch alloy wheels, auto LED headlights, a reversing camera and a tyre pressure monitor, while inside you’ll find a 10.0-inch touchscreen with Apple CarPlay and Android Auto capability (both wired) with four speakers for the sound system, as well as a push-button start, synthetic leather seats and three different selectable steering modes.

Stepping up to the Essence, which we’re testing here, costs $28,990 drive-away and adds a sunroof, a six-speaker sound system, electric seat adjustment for the driver, steering wheel paddle shifters - for a reason we’ll return to - and turns the rear-view camera into a surround-view parking camera.

The Essence is also visibly different on the outside thanks to slightly larger 17-inch alloys, auto-fold (when locked) side mirrors, and a grey grille insert rather than body-coloured.

On that, you can have white or yellow as no-cost paint colours in either MG5 variant, but metallic red, blue, black or grey are all $700 options.

It's a beast of a power plant - a twin-turbo 2.9-litre six-cylinder TFSI that will deliver 331kW at 5700rpm and 600Nm at 1900rpm, sending it thundering to all four wheels (because quattro) via an eight-speed tiptronic automatic.

That's enough, says Audi, to deliver a 0-100km/h sprint time of 4.1 seconds, which is plenty quick. 

Both versions of the MG5 come with a 1.5-litre four-cylinder engine that drives the front wheels, but the similarities mostly end there.

In the entry-level Vibe, that engine is naturally aspirated and makes 84kW and 150Nm - similar to the MG3. Power is transferred to the front wheels via a continuously variable transmission (CVT).

In our Essence variant the engine is turbocharged and makes a suitably higher 119kW and 250Nm, driving the front wheels via a seven-speed dual-clutch automatic transmission.

Audi says you'll get 9.5L/100km on the combined cycle, and emit 218g/km of CO2. But not if you drive it like you'll want to drive it. Get a little too familiar with the accelerator and you can expect that number to climb.

The RS4 Avant is fitted with a 58-litre fuel tank.

The naturally aspirated Vibe's official combined cycle fuel economy figure is 5.7 litres per 100km, while the turbocharged Essence drinks a little more at 5.9L/100km.

For comparison, Toyota claims its non-hybrid Corolla Sedan will sip 6.0L/100km, while a Mazda3 Sedan claims 6.1L/100km. Not bad, then, if you can keep it near MG’s claim.

During our testing, with a mix of city, suburban, highway, and rural driving, the MG5 Essence burned through 95 RON premium fuel at a rate of 9.1L/100km, checked at the pump, though I wouldn't expect this to be representative of normal, calmer day-to-day driving.

It's a thundercat, the RS4 Avant, and might well be among the world's most undercover sleepers, given its ability to deliver near-supercar pace from its fairly understated station wagon body shape. 

Sink into the driver's seat, grip the chunky, leather-wrapped steering wheel and kick over the engine, and the low rumble of then exhaust immediately informs you that you're in something with some serious performance potential.

The acceleration is properly addictive, with the RS4 piling on speed on the exit of corners, shrinking the gap between bends so much that you're hurriedly standing on the brakes again as you barrel into the next turn before you know it.

It feels properly, properly sporty, and you can't help but feel a little smug about the fact you can effectively pour an entire Bunnings into the massive boot, where people in true supercars are lucky if they can fit even fit themselves in them. 

And I think that's the magic of a car like this, that straddles that line between practical and potent with such aplomb, it feels like it you're not making much in the way of sacrifices, and you can knock off the school run or a hill sprint with equal ability.

Downsides? Well, even in its angriest settings, the gearbox felt a little fidgety at pace, shifting up or down at strange moments on the way into or out of corners. You can take control via the paddle shifters, of course, but it wasn't the most intuitive gearbox I've experienced. The steering, too, felt a little - and I  mean a little - disconnected, even in its sportiest settings.

Perhaps the biggest surprise about the MG5 is that it’s quite good to drive. And not just ‘for an MG’ or ‘for a car from China’. It’s actually good.

The turbocharged engine takes a moment to get going, and the dual-clutch can be a little hesitant off the mark.

The combo of the two means sometimes you need to plan your take off ahead of time - but in its above-3000rpm sweet spot, the Essence has a good bit of urgency to it.

That’s fortunately paired with a combination of comfortable suspension and a composed chassis, with well-weighted steering.

On urban roads and with a little awareness of the slow take-off, the MG5 is capable and well-suited to small roads, though it can be a little frustrating in stop-start traffic.

On the other hand, outside the confines of city driving, the small sedan is more dynamic than you might expect, able to get up to speed and comfortably overtake on highways, as well as handle corners on twisty roads confidently.

Potholes and rough sections of road don’t rattle the MG5 as much as you might expect from a car in this segment, though road noise can be a intrusive on coarse roads - of which Australia has many.

Dare I say it - the MG5 is rather fun.

Here’s the bit that might turn potential owners off the MG5. Or here aren’t the bits, more accurately.

The MG5 comes with a short list of safety features that amount to the minimum standard for a car to be sold in Australia.

That is, six airbags, autonomous emergency braking (AEB), anti-lock brakes (ABS) and electronic stability control (ESC).

MG also lists hill-hold under its safety features, as well as its active cornering brake control and auto door unlock and activation of hazard lights in case of an accident.

There are also ISOFIX and seat tether points for the outer rear seats.

The reverse camera in the Vibe is replaced by a surround-view camera in the Essence, though the visual quality of the feed leaves a bit to be desired.

Crucially, it’s missing a host of safety features that would be standard, or at least optional on a rival like the Toyota Corolla Sedan or Mazda3 Sedan, like steering assist, a pre-collision safety system, pedestrian detection, active cruise control and even lane departure alert.

Rear cross-traffic alert and blind-spot monitoring? Nope.

MG Australia CEO Peter Ciao told CarsGuide not long ago it’s about keeping the price of the car accessible for more customers, which means you’ll have to make your own call regarding whether it’s safe enough for you.

To that, ANCAP hasn’t crash tested the MG5, but if it did we wouldn’t expect it to score any higher than three stars.

While we don’t know how it would hold up in the area of crash protection, it lacks too much of the active safety gear that ANCAP expects of a maximum five- or even four-star car.

Audi vehicles are covered by a three-year, unlimited-kilometre warranty, which is feeling more than a little underdone when compared to some competitors.

Services are due every 12 months or 15,000kms, and Audi allows you to pre-pay your service costs for the first five years, at a cost of $3,050.

MG offers a seven-year/unlimited kilometre warranty on the MG5 as with all its models - even electric cars. That also comes with roadside assist for the duration of the warranty, though only 160,000km is covered by the warranty if the car is used for commercial purposes.

Servicing prices for the MG5 range from $266 or $272 for the Vibe or Essence, respectively, up to $581 or $661 for the most expensive of the seven 10,000km/12-month scheduled services.

The total cost of servicing the Vibe over its seven years under capped-price servicing comes to $2661, or about $380 average per service. For the Essence, that bumps up to $2764 or an average of about $394 per service.
