Audi A3 vs BMW X3

What's the difference?

Closing in on $60,000 for a small car isn’t cheap. Ask a car dealer and they might even say the hatchback is a good way to get someone into a showroom to eventually look at an SUV.

But I reckon you’d be doing the A3 a disservice to count it out. It’s always been one of those cars that does everything well, and with this current facelift manages to keep its practicality without becoming boring.

It looks good on the outside, it’s smart on the inside and it’s fun to drive while remaining sensible. Even if you get it in bright yellow.

If a BMW X3 is for you, then we have no quarrels with that. It’s a better all-round vehicle than the one it replaces and represents better value. And even though BMW mandates a hybrid driveline, there are still some significant choices within that framework.

By all means buy the M50 if you crave the rush of acceleration that almost 300kW can provide. And if efficiency is your altar of choice, then the plug-in 30e makes a lot of sense, too.

But even if you can afford either of those two more expensive variants, whatever you do, don’t dismiss the entry-level 20 model. At least drive it alongside the others and then make a decision based on all the facts, and not the assumption that entry-level equals the car you afford rather than the car you want.

It might be cheaper, but there’s absolutely no doubt that the 20 model is the one that shines and arguably makes the most of the opportunities BMW’s latest tech offers.

Sometimes less really is more.

Eye of the beholder and all that, sure, but the A3 looks cool from the outside. It’s got this angular design but manages it without being too aggressive or busy with other design elements, so it still has a ‘premium Euro’ feel to it.

Shooting pics of the car for this review, the harsh light accentuated its sharp lines. It looks sculptural rather than just some little blob. 

At the same time, thanks to the proliferation of sports design packs like the S Line, The A3 looks like it could be an S3, almost. Which makes sense, because the front bumper and rear diffuser as well as the roof spoiler are all partly inspired by RS models.

New for the A3 is the flat, 2D Audi badge, the model name on the B pillar and the new font for its name on the tailgate. 

The lights in the cluster are able to look narrower than before thanks to their customisable settings, which allow you to choose the light signature, while the grille has a flatter appearance and the air intakes are bigger. Even the wheels look like they’re from a sports car.

Whether you’d have the A3 in the Python Yellow of our test car is another thing. I don’t mind a loud colour but I reckon a bit of 'District Green', 'Ascari Blue' or 'Progressive Red' would be the vibe.

Also, any colour that isn’t white is a cost-option on the A3, all of them coming in at $1350, except Ascari Blue which is an Audi Sport colour and costs $1850.

Speaking of the vibe, inside the A3 feels properly nice. It’s not just a spruced up Golf in there. There’s proper Audi character to the car, though that means plenty of piano black trim to get smudgy.

Audi’s done a good job making the layout look sleek without resorting to locating all the controls in the screen. There are design elements in the cabin that aren't strictly necessary but are worth doing for the way they look.

Things like the way the vents flank the driver display or the trim inlay on the passenger side of the dash.

It might be badged an X3, but this is no small vehicle. In fact, it’s bigger than the original BMW X5 (which set the tone for this entire market segment) with a length of 4755mm (4667mm for the first X5) and a width of 1920mm (1872mm). That said, it’s 25mm lower than the outgoing X3 in a move to emphasise its sportiness. Shorter it may be, but it’s also 16mm wider on the front track and 45mm wider on the rear than the outgoing model.

BMWs latest styling cues also appear in the new car, including the large, split-kidney grille that, for Australian-delivered cars, is also lit around its edges. The short overhangs that characterised the original X5 (and soon characterised this whole BMW genre) remain, and the T-graphic LED tail-lights round out the stylistic touches.

The other thing we noticed (and we’ve seen it on other cars recently) is a panoramic sunroof that doesn’t actually open.

Starting from what’s right in front of you as a driver, the steering wheel is the same as in bigger, more expensive Audis. That’s a good thing, because it’s nice to hold, has a good shape for the nine-and-three hand position and it’s not too thick. 

As well as the nice, clear buttons on the wheel, you’ve got some physical controls for the climate control and some of the vehicle functions like parking assist and stop-start under the multimedia screen.

For a car this size, the 10.1-inch central touchscreen is plenty big enough, and the fact it doesn't sit up high over the dash is great. It's like a perfect arm's length for your standard-sized adult (like me). I can reach the other side of the screen without needing to lean.

The fact there’s no head-up display is a bit of a let-down, but the now-standard 12.3-inch driver display is very good. It’s configurable yet clear, and means you can get detailed navigation information in front of you rather than having to look to the multimedia screen. 

The test A3 has genuine leather upholstery, which is $1100 extra. Not the most you’d pay for leather seats in a Euro, and the seats are comfortable. They're nicely bolstered, the drivers’ side is electrically adjustable and the leather doesn’t feel hard or rough to the touch.

Sitting behind my own seating position in the second row is a little tight, however. At 178cm, my knees almost touch the seat in front. There's also no sunroof, and even though there's just about enough light, that omission doesn’t help the cramped feeling.

There are, like the front, two USB-C ports and the air vents in the back, the latter separately adjustable to avoid arguments, though the cupholders in the armrest are in an awkwardly central position.

Behind that, under the 380-litre boot's floor is a space-saver spare tyre. That's better than some SUVs designed for family adventures that only offer up an inflator/repair kit. Keep that up, Audi. Good job. Well done. 

If you fold the rear seats, you get 1200 litres of space. Interestingly, those luggage space figures are the same as the BMW 1 Series.

Cabin space is plentiful in the X3 with loads of room in the front, possibly thanks to the dashboard that is pulled back from you with only the twin screens and steering column offering themselves up to the driver. Even the air-vents are somewhat hidden. There’s good vision out and the seats themselves are lovely. The step into the cabin feels to be at just the right height, too; not too high, not too low.

Rear seating is good, too, although the X3 will always be better as a four seater than five thanks to the shape of the rear bench, but the glass roof opens the space up and there’s plenty of charging points and storage nooks. The sun blinds on the rear-side windows of the more expensive versions should be standard kit on every car sold in Australia.

We’ll take exception to the new gear-selector which doesn’t have a defined Park position and instead relies on applying the park-brake to engage Park. But the ambient light and contrasting cabin colours are a bit of a breath of fresh air.

There are levers in the cargo area to quickly fold the rear seats (60:40) at which point luggage space jumps from 570 litres in the mild hybrid cars to 1700 litres. The battery-pack of the 30e model means that luggage space starts at 460 litres and can be expanded to 1600 litres.

The latest version of BMW’s sometimes controversial iDrive operating system is simpler and easier to use than before and supported by a new operating system, but there’s still some familiarisation necessary. One improvement has been the addition of QuickSelect which works somewhat like the old favourites button system and gets around the need to drill into menus to access the functions you want.

A head-up display is a terrific addition, although where some displays are more tolerant of polarised sunglasses, the HUD in the BMW didn’t like mine and went dark at the most inconvenient angles.

None of the X3 variants feature a spare tyre of any sort. The 19-inch tyres on the base grade are run-flats, while everything else gets a repair kit for roadside emergencies.

If you want to tow, the good news is that all X3 variants can do so. But you will need to purchase the $2200 towing package which enables the X3 to haul a trailer weighing up to 2000kg with a maximum tow-ball down-weight of 200kg.

The new X3 range kicks off with three distinct models. There’s the entry-level 20 xDrive at $86,100, the 30e xDrive at $104,100 and the big-hitting M50 xDrive at $128,900, all before on-road costs.

Both the 20 xDrive and the M50 xDrive feature a 48-volt mild hybrid driveline, while the 30e xDrive goes all the way with a plug-in hybrid (PHEV) layout. All variants also feature BMW’s permanent all-wheel-drive system.

BMW claims greater standard equipment than ever before, and even the entry-level 20 xDrive has plenty of kit including 19-inch alloy wheels, tri-zone climate-control, the virtual cockpit screens with a curved central info screen, a six-speaker, 100-Watt stereo, acoustic glass, auto headlights, an auto tailgate, keyless entry and start, digital radio, powered and heated front seats, wireless Apple CarPlay and Android Auto and wireless phone charging.

The PHEV model adds 20-inch alloys, the M Sport package including blue brake calipers, and a leather steering wheel, as well as the Comfort Package which adds heated seats for the second row of outer seats, a roller sun-blind for each rear-side window, ventilated seats, a heated steering wheel, tinted glass and a luggage net. The 30e also gets parking assistant, a panoramic sunroof (a non-opening one), and a surround camera system.

Move up to the M50 variant, and you’re in for no-cost metallic paint, 21-inch alloys, a 15-speaker stereo, quad exhaust tips, M-specific details such as the mirror caps and aero add-ons. You also get a range of kit as standard that comes as an extra-cost option on the other two variants. Those include the enhancement pack that includes an alarm system, surround sound, M Sport Pro Package (various trim highlights, red brake calipers, M seat belts) and the Comfort Package that is also standard on the 30e.

The value headline is that, compared with the previous model, some variants of the new car are actually cheaper on an apples-with-apples basis. The base model car in its previous form was, by the time you added the now-standard M Sport package, dearer at $88,100, and the previous 30e optioned to include the standard kit the new car has, (heated rear seat, acoustic glass, roller blinds and more) was also (much) more expensive at $111,800. And although the M50 model in its previous guise was slightly cheaper at $126,800, it lacked the hybrid driveline, metallic paint and M Sport Pro package the new car has as standard.

The A3 is powered by a 1.5-litre, turbocharged four-cylinder petrol engine that makes 110kW and 250Nm.

It drives the front wheels via a seven-speed dual-clutch auto transmission and it can hit 100km/h in a claimed 8.1 seconds.

It’s also got a 48-volt mild hybrid system to help with efficiency, though you’d need to be told about it to notice. It also helps with the A3’s (smooth) stop-start system.

Hybrid tech across the board is the key phrase here, with the base-model 20 xDrive fitted with a mild hybrid electric motor and battery pack that works in conjunction with the 2.0-litre, turbocharged petrol four-cylinder engine. Power is 140kW and torque 310Nm. Like most mild hybrids, the electric motor offers power regeneration during braking, a mellow (by EV standards) kick in the pants during take-off and acceleration and also acts as the car’s starter motor.

The performance flagship, the M50 xDrive taps into the same technical philosophy with a mild hybrid augmenting the turbocharged six-cylinder inline petrol engine. In this case, however, peak power is a hefty 293kW and torque maxes out at 580Nm.

The most technically adventurous X3 is the 30e xDrive which uses plug-in hybrid tech to offer a claimed 91km of electric driving, about twice that offered by the original X3 PHEV it replaces. When the same 2.0-litre four-cylinder petrol as fitted to the 20 xDrive, and the electric motor are humming along together, there’s 220kW of power and 450Nm for the taking. The PHEV X3 can run in purely electric mode at up to a claimed 140km/h.

All variants use BMW’s familiar eight-speed automatic transmission and in each case, drive is sent to all four wheels on a permanent basis. Interestingly, the 30e and M50 versions package their electric motor as part of the engine-transmission combination. The 20, meanwhile, places its electric motor externally, as part of the drive-belt rotating assembly.

The M50 model has an M button that unleashes the full performance with one touch, and features an electronically locking rear differential in the interests of high-speed turn-in.

Adaptive suspension that varies the degree of damping is also part of the package on each X3 variant.

The A3’s 50-litre fuel tank needs to be filled with RON 95 premium fuel and it’ll drink a claimed 5.3-litres per 100km on the combined (urban/extra-urban) cycle.

Theoretically you’re topping 900km a tank there, but given how fun this car is to drive you’d have to be well behaved to get even close.

For reference, whenever I was on a normal, day-to-day drive on test the A3's trip computer was returning figures in the mid to high sixes.

As you might expect, the PHEV 30e model is the efficiency superstar of the X3 line-up with an official combined test figure of just 1.6 litres per 100km and 38 grams of CO2 per kilometre. The four-cylinder 20 xDrive is not bad for its size at 7.5L/100km (and 171g), yet the bruising six-cylinder M50 version with all that performance is not too far behind with an official figure of 8.2L/100km (187g).

The 30e PHEV features a selectable battery-saving mode as well as the option of forcing EV-only running. It features a 19.7kWh battery and BMW claims it can charge using a three-phase, 11kW socket from empty to full in two hours, 15 minutes. It does not make use of fast-chargers.

Exactly how far you’ll travel in the PHEV model will depend hugely on how and where you drive. On long, open road journeys, fuel consumption won’t be much different to the others, but with just a 50-litre fuel tank, it’s range won’t be stellar. But in urban running where the batteries are being recharged for free as you brake, the difference will be significant. Meanwhile, with a 65-litre fuel tank in the mild hybrid grades, the theoretical range (based on the official fuel number) is 865km and 765km for the 20 and M50 respectively.

While BMW recommends premium fuel for maximum efficiency, it also says that each X3 variant will not be harmed by the use of standard ULP if that’s all you can get hold of.

First things first, the A3’s exterior and S Line pack are a clue to the way the car drives. It’s probably not the perfect car if you like a cushy, soft ride. 

Its suspension errs towards the stiffer side of things, and certain bumps can feel more significant than they need to. But even on particularly bad roads or tram tracks in the city the dampers do a decent job of soaking up the harsh stuff.

It also means there’s more road noise than you’d like on some older highway surfaces, but only in a way that might get annoying if you’re on a road trip with the stereo off for some reason.

The upside of that is its steering feels well weighted and accurate. Plus, the way it handles and corners feels like a bit more grunt would make this a proper driver's car.

It’s not too intense, and there’s enough feedback to make it feel like the A3 shouldn't be a city-dweller only when it comes to driving.

Of course, it’s a hatchback, so you've got the advantages that come with less weight and a lower centre of gravity. 

It doesn’t have enough weight to push into understeer more than you’d like on a tight corner. But it also doesn’t feel so light that you’re not sure how it’s going to behave under sharp braking.

The A3’s drivetrain, despite looking underwhelming on paper, feels practical on the road. Sure, 110kW isn't anything wicked, but its 250Nm feel like they’re working in the right places - that being between 1500 and 3500rpm. 

It isn't blisteringly quick but even with the seven-speed transmission operating in default auto mode it usually feels like it's in the right place, let alone chipping in with 'manual' shifts via the paddles or shifting drive modes. The A3 has a choice of 'Normal' and 'Sport' shift settings.

You might be a little disappointed if you thought you’d be getting anything approaching a hot hatch, but for an entry-level model the A3 more than holds its own. It’s a solid platform that performs well without compromising too much when it comes to daily driving ability.

Big heavy SUVS like this one haven’t always been too dainty on their feet. The extra bulk and height mean suspension has to be firmer, the big wheels and subsequent loss of tyre sidewall depth plays against ride quality and before you know it, the compromises have piled up and the driving experience has gone to hell.

This time, however, BMW’s claim that the X3 was designed from the start as an SUV and not converted from a sedan platform seems to hold water. There’s an overall greater sense of cohesion in the way the car steers and flows through corners and faster bends. The steering feel and feedback are a big part of that, too, and the whole seems at least as great as its parts.

The M50 is, predictably, a rocket with loads of accessible acceleration and a great noise while you’re enjoying it. That said, the 21-inch wheels and tyres don’t do anything for ride quality, but it remains an entertaining performance car in a familiar, ICE kind of way.

The plug-in is also perky with its 220kW on tap, but it’s less old-school and more techy. And while you can’t pick the point at which ICE hands over to electric and vice-versa, sensitive drivers will absolutely know that there’s a big dollop of electrical assistance when your right foot starts asking the tough questions. It definitely feels more overtly hybrid, though that shouldn’t be any kind of surprise, purely because that’s precisely the case.

Which brings us to the 20 entry-level grade. And while it’s going to be a controversial statement, this emerges as the most cohesive, rounded variant of the new X3. There’s something in the way the fizzy, bubbly (but very smooth) 2.0-litre four-cylinder provides more than enough urge, but never threatens to dominate the dynamics.

With less weight over the front wheels than the M50, and less weight overall than the PHEV, the 20 corners flatter, steers more intuitively and is simply more fun more of the time. Even on the optional 20-inch tyres, it rides better than the others, too, and might even be better again with the standard 19s other than the fact that those are run flats and we didn’t get try them.

The X3 – not too surprisingly – runs to all the latest driver assistance programs starting with autonomous emergency braking (AEB) that can identify pedestrians and cyclists. There’s also front collision warning, lane departure warning, parking assistant and a surround camera system. There’s also lane-keeping assistance which is calibrated perfectly and should be the standard for this type of otherwise intrusive technology.

You’ll also find front and rear cross-traffic warning, adaptive cruise control and tyre pressure monitoring.

The X3 hasn’t been ANCAP tested and there’s no real likelihood of that happening in the future.

Audi offers a five-year/unlimited kilometre warranty, which is about par for a premium brand, but it also offers five years' free roadside assist and the ability to pay to extend the warranty.

Servicing is $2520 for a five year plan, but the extended two years of 'Audi Advantage' warranty is $3250 and comes with unlimited kilometres, roadside assist and covers two services.

BMW’s warranty on the X3 is the company’s usual five-year/unlimited kilometre deal. But in this case, there’s also a six-year/100,000km warranty on the high-voltage battery.

Also typical for BMW is the service interval which is not a set time or distance and instead is determined by how the car has been used. It’s called condition-based servicing and it’s nothing new at BMW.

There’s also capped-price servicing available. For the X3, the five-year/80,000km service package is $2475.
