2022 Audi A3 vs 2023 BMW 330e

What's the difference?

Producing a car that takes the end result beyond appliance status is no given in a world car-park dominated by SUVs. But Audi has, over the last few decades, shown it is very good at doing just that and the latest incarnation of its A3 stalwart backs that up.

While it might take a bit of mental gymnastics to understand why the base model gets the hybrid driveline, or why the more expensive variant costs more to option with adaptive cruise-control, the fact remains these are driver’s cars from a company that understands that concept.

Yes, the A3 is a relatively expensive way to arrive at a compact hatch or sedan, but if you value the journey as much as the destination, it will all make sense.

While the technical aspects of the 35 TFSI are interesting, the extra power and all-weather grip of the AWD 40 TFSI seem to be worth the additional dollars to us. The A3 has always been a sporty alternative, meaning the sportiest version is the one for us.

CarsGuide attended this event as a guest of the manufacturer, with meals provided.

The 330e M Sport is an excellent car, but it could be a much better hybrid.

In Australia, where driving distances can be vast, a car that's as comfortable and easy to live with as this one is welcome. But for the electric range to dissipate so quickly, and not recoup again at a fast enough rate without plugging into a charger, is disappointing.

There are other plug-in hybrids, even among the more affordable mainstream brands, which can return charge to the battery incredibly quickly and effectively on the go.

If you are looking to make the step into a hybrid, then perhaps consider a fully electric car. There isn't a battery electric 3 Series on the market in Australia (yet), but BMW does sell the iX1 small SUV for less money than a 330e or the iX3 for a tad more.

Both are pure electric SUVs and have a range of between 400-500km. You'll never need petrol again, which makes a hybrid seem outdated.

It’s actually refreshing in 2022 to see a carmaker putting such an effort into something that isn’t an SUV.

That Audi has bothered with two distinct bodies and two equally distinct drivelines is also one for the books, really.

Technically, the mild-hybrid driveline as seen in larger Audis in recent years is probably the highlight of the new A3, and even though it doesn’t compare with a conventional petrol-electric hybrid, it demonstrates Audi’s attention to detail.

The same goes for the digital instruments which allows the driver to tailor the information displayed at any given time. Need a city map more than you need a tachometer at a particular point in you journey? That’s where this technology comes into its own.

Once upon a time sedans were all we drove, well mainly. Then SUVs became the style of car most people wanted. In fact, three out of four new cars sold in Australia today are SUVs.

So, I commend you on your choice of not just doing what everybody else does, and you'll be rewarded with better driving dynamics, and ownership of an iconic BMW - the four door, 3 Series.

And even though this is a plug-in hybrid version of the 3 Series it's identical in styling to the petrol variants. Only the light blue border around the BMW roundel is the indication that it's an electric vehicle. That and the charging flap near the left front wheel.

The M Sport pack adds some very sexy features such as the M Sport aerodynamic body kit, the door sills and M Sport seats, but the M Sport Pro Pack our car came with adds a black gloss grille, boot lid spoiler and the snazzy seat belts.

The cabin's double screens are impressive but I miss analogue gauges and found the digital instrument cluster overly busy and led more by cool design than functionality.

Although it’s a compact car externally, clever packaging means there’s ample space inside. Even a tall-ish rear-seat passenger can sit behind a tall-ish driver, and the sculpted rear seat-backs help make that possible.

The only complaint would be that the dark headlining material makes the interior a bit of a cave at times.

Paying more for the 40 TFSI gets you extra cargo nets on the front seat backrests and luggage area, 12-volt sockets in the rear seat and boot. Both versions get floor mats and a centre arm-rest front and rear.

The rear seat in either is split 40/20/40 for a range of possibilities, with the Sportback offering 325 litres (VDA) for the Sportback quattro models, and 380L (VDA) for the 2WD models and its boot capacity is increased to 1145L (VDA) with the rear seat folded flat. The luggage space in the sedan is 390L (VDA) for the quattro AWD version, and a more capacious 425L (VDA) for the FWD model.

People will tell you SUVs are more practical than sedans... and they're right, but not in as many ways as they probably think.

The cabins of sedans and SUVs of the same size are close in terms of space, but the 330e comes with excellent storage - better than many SUVs I've tested, featuring enormous door pockets, and a deep centre console storage bin.

There are four cupholders, too. Two in the fold down armrest in the back and another two up front.

There's also wireless charging up front, plus USB ports for the back passengers. The second row also has its own climate control and directional air vents.

Legroom is excellent in the back and I can sit behind my driving position with plenty of room to spare. Headroom is also excellent thanks to the tall roofline of the 3 Series.

Where a sedan isn't as practical as an SUV is its ride height, which makes getting in and out of the latter easier (although the 330e's doors open very wide) and its boot opening.

SUVs have hatch-like openings and that offers a wider and taller aperture for carrying cargo.

The 330's boot was still big enough to fit our two largest CarsGuide suitcases (see the video), but the location of the battery means cargo capacity has been reduced from 480 litres in a petrol 330i to 375 litres in this 330e.

The BMW 330e M Sport lists for $97,400, which is $4000 more than its 330i petrol twin.

The M Sport part of the name is there because the 330e comes standard with the M Sport pack. And that gives you a tough body kit, M Sport suspension, M Sport seats and aluminium trim, as well as M Sport door sills.

The car we tested and the one you can see in the video and images also comes with the 'M Sport Pro Package'. It costs $2800 and adds a boot-lid spoiler, glossy black grille and tail pipes, and M Sport seat belts, among other goodness.

This car also had the optional 'Visibility Package' fitted. It costs $4800 and adds a sunroof and adaptive LED headlights.

There's no direct rival for the 330e in Australia now. Mercedes Benz used to have a C300e, a plug-in version of its C-Class, but retired it locally some time ago.

The standard features of the 330e M Sport are identical to the 330i M Sport.

So, along with that M Sport pack also coming standard on the 330e is a head-up display, a 12.3-inch digital instrument panel, a 14.9-inch media screen with sat nav, Apple CarPlay and Android Auto, three zone-climate control, wireless phone charging, digital radio and power adjustable front seats.

Is it good value? There's a stack of equipment, tech, beautiful M Sport additions and it all feels superbly high quality. But knowing you can have a 330i for less means you're paying more just for the hybrid system. So, let's talk about that...

While both versions of the A3 use a seven-speed dual-clutch transmission (no manual gearbox will be offered) there’s not a lot of commonality beyond that.

So let’s start with the 35 TFSI’s mild-hybrid running gear. To begin with, mild-hybrid in this sense refers to a starter motor/alternator unit that is linked to a 48-volt battery (the car also has a conventional 12-volt electrical system).

When coasting, the engine can shut off and the starter switches to alternator mode and harvests the otherwise lost energy to charge the 48-volt battery. This 48-volt system also powers the car’s functions when the engine is switched off.

When the car needs to restart (when the traffic-light goes green) the starter kicks in, using that harvested voltage. There’s also a regenerative braking function, saving the car’s actual brakes for more severe stops.

Unlike a 'normal' hybrid system, there’s no electric motor to help drive the car, but Audi claims a potential fuel saving of 0.4 litres per 100km from the set-up. Any benefit will be most noticeable in urban running where the car is speeding up and slowing down regularly.

The rest of the 35 TFSI is technically interesting, too, with the 1.5-litre four-cylinder turbocharged engine featuring cylinder-on-demand where it can shut down individual cylinders during cruise conditions to save fuel.

When firing on all four, however, the engine is good for 110kW of power and 250Nm of torque, figures which have become almost an industry standard in this sized vehicle.

The 40 TFSI, meanwhile, ditches the hybrid gear for a conventional 2.0-litre powerplant with a turbocharger and 140kW of power. Torque is a handy 320Nm and is developed over a wide range of engine speeds (anywhere from 1500 to 4100rpm).

The other big difference is in the driveline. The 35 TFSI is a front-wheel drive platform while the 40 TFSI uses Audi’s Quattro AWD as it applies to Audis with an east-west engine layout.

That means the car behaves as a front-drive vehicle until the electronics decides more power should be sent to the rear wheels. At that point, anything up to 99 per cent of the available torque can be transferred rearwards via an electronically-controlled multi-plate clutch housed at the rear of the car, just in front of the rear axle.

The 330e M Sport has a 2.0-litre petrol engine and an electric motor. The engine makes 135kW while the motor produces up to 80kW, for a combined dollop of 215kW. Total torque is more than sufficient at 420Nm.

Acceleration to 100km/h from zero feels as quick as the 5.8 seconds BMW claims and that's also about a tenth of a second brisker than the 330i.

The 'XtraBoost' function combines the total output of both the engine and motor briefly providing that great acceleration.

An eight-speed automatic shifts gears smoothly with the drive going to the rear wheels.

I like all this very much - the responsive engine, the fantastic transmission, the extra oomph from the motor and the way it all works together seamlessly. It's just a shame it's not as efficient as some other new plug-in hybrids.

With all its cylinder shut-off, hybrid tricks and small capacity, the 1.5-litre engine boasts a 5.0 litres per 100km combined cycle fuel economy figure.

Combined with its 50-litre tank, that’s a potential for 1000km between service-station visits. It’s also commendably close to the numbers you’d expect from a similarly sized vehicle with a turbo-diesel engine.

The more conventional 2.0-litre A3 variant, meanwhile, boasts a still-credible 6.7 litres per 100km for the same test. To counter its greater thirst, Audi has fitted a slightly bigger, 55-litre fuel tank.

The headline act, of course, is the base-model’s highway figure which, thanks to the small capacity engine and its reduced pumping losses at small throttle-openings, can get right down into the low-fives (5.0 litres per 100km) in the real world at real highway speeds.

With a tail-wind, you might even see a number starting with four. This is why you don’t need a diesel engine any longer.

Expect the 40 TFSI to use roughly a litre more across every 100km travelled. And in either case, you are stuck with paying for 95-RON premium unleaded.

The 330e M Sport is a plug-in hybrid which must be connected to an external power source regularly to charge its 12kWh battery.

The charging flap is located on the left side of the car near the front passenger door, which worked well for me as I could steer the 330e into my driveway and connect to a powerpoint on the wall using the charging cable provided.

It took me about six hours to charge the battery to 100 per cent from zero and that gives you a maximum 57km of electric driving range.

During my four days with the 330e Sydney's summer temperatures were hitting 34-degeres Celsius and with the climate control keeping the cabin at a hospitable 18C electric range was seriously cut short to about 40km.

I drove the 330e in hybrid mode nearly all the time - this is a hybrid after all. But there is a 'Sport' mode for more grunt and a 'Battery Hold' mode to save the charge for later.

I started with a full charge and a full tank of petrol, and for four days I lived with the 330e as I do with all my test cars.

I didn't aim to get the best fuel economy ever, nor was I wasteful with fuel. My wife and I, plus our two kids, just used it as our family car, doing trips to the beach, endless laps of the supermarket car park looking for a space, a birthday party, the lot.

I drove 154.7km over those four days and charged it on the second day after the battery was drained completely before driving another 70km or so over the next couple of days.

When I filled up after this it needed 7.74 litres to reach full again - it's a small 41 litre tank.

That converts to average fuel consumption of 5.0L/100km, which is bang on double the 2.5L/100km BMW says you should get.

I don't doubt you could get 2.5L/100km, but you'd have to be doing short trips and charging almost every time you weren't driving. And not use the climate control on an icy blast setting.

I've tested other plug-in hybrids that achieved much better mileage and that's because their on-board charging capabilities were excellent.

Some were even able to use the petrol engine to power the motor in reverse and therefore act as a generator to recharge the batteries fully.

The 330e M Sport doesn't do a good job of charging its battery while on the go. Sport mode does recoup charge to the battery, but again, if you're doing a long motorway trip that charge evaporates fast.

I don't think this type of plug-in hybrid is suited well to our country where we don't blink an eye at travelling 100km for Christmas lunch and then drive back again.

Also think about if you ever go on a trip away and don't have access to a power point or public charger. It's happened to me.

Let’s start with the less powerful 35 TFSI, if only because - even though we know better in 2022 - there’s a temptation to think a 1.5-litre engine will be underdone. The reality, however, is that you’re not going to drive this car and judge it as anything other than very resolved.

While it’s true the peak power of 110kW isn’t startling, it’s the way it’s delivered (along with the 250Nm of torque) that sets the mood here.

Like many late-model Audis, this one has an engine with a fizzy, zingy feel that makes you want to rev it just to hear and feel it. And when you do, it pays off with plenty of flexibility and a sophisticated, refined feel.

Whether the mild hybrid driveline is adding anything to the formula is debatable, because the technology is so seamless you won’t pick what it’s doing other than the engine stop-start function, which is one of the better ones we’ve sampled.

Move from the 35 into the 40 TFSI and you immediately notice the extra power and torque on tap. And although it’s still not a hot-hatch by modern standards, there’s always enough urge to make the 40 TFSI a convincing driver’s car.

Again, the power delivery is the key to it all, making more of what the engine has to offer by actively encouraging you to use it. The seven-speed dual-clutch transmission is your friend here.

The extra driveline functionality of the 40 (namely the AWD system) actually means less than you might imagine in day-to-day life. We didn’t get to drive the car in the wet, but it’s fair to say that those conditions (or a loose, gravel road) are really the only ones likely to make a difference to the way the basic platform feels.

That’s for two reasons; the first being the all-wheel-drive is fundamentally on demand anyway and, secondly, the basic platform is so composed and balanced in the first place, that the Quattro system will spend a lot of its time hiding in the background.

The 40 TFSI also get the selectable drive modes which break with tradition by actually making a difference to the way the car feels.

But the reality is that if you took the best bits of every other setting (Comfort, Dynamic and Efficiency) and loaded them into the Individual button, you’d probably wind up with something very close to what the non-adjustable 35 TFSI offers in the first place.

You have to admire the way Audi has made a front-drive car in the A3 steer, handle and talk to the driver in such a clear, precise way.

Yes, the 40’s selectable modes add another layer to that, but only if you can be bothered. Even more than that, the A3 in either form feels like its ultra-stable and safe, while the levels of feel and feedback give the impression they were decided upon by people who enjoy driving.

The 330e M Sport is outstanding to drive. The driving position is superb, the steering is effortless and accurate, handling is excellent and the ride is beautifully comfortable.

Brake pedal feel is surprisingly good for a hybrid - some have a wooden sensation.

The transition from electric motor to petrol engine is also remarkably smooth.

Acceleration in Sport mode is sudden, with the engine and motor combining their mumbo to move you. There is a 'fake' or synthesised exhaust note in Sport mode, but it sounds convincing.

Speaking of sounds at lower speeds, in fully electric mode the 330e emits a warning tone to alert pedestrians of your presence. It's quite loud in car parks and does actually make people turn around looking for a UFO.

The 3 Series was awarded the maximum five-star ANCAP rating when it was tested in 2019. The 330e comes standard with AEB, lane keeping assistance, blind-spot warning and rear cross-traffic alert.

There are excellent cameras front and rear and LED headlights, too.

Adaptive cruise control is also standard on the 330e M Sport.

Audi recently improved its factory warranty from three years to five years and unlimited kilometres. Any new Audi (including this one) sold after January 1 this year is the beneficiary of that change.

Audi specifies service intervals of 15,000km or 13 months.

There’s also the option of a fixed-price servicing program for the first five years of A3 ownership, and that will cost you $2250, for an annual average of $450.

The 330e M sport is covered by BMW's five-year/unlimited kilometre warranty. The hybrid battery is covered by a six-year/100,000km warranty.

BMW offers a five-year/80,000km service package for the 3 Series for $2150.

Service intervals are condition-based, and the car will let you know when it's time for a check-up.
