Audi A4 vs BMW 330e

What's the difference?

The Audi A4 allroad 40 TDI quattro S Tronic is a nice-looking wagon that’s fun to drive.

It’s packed with tech, adequately functional for daily life and it’s also capable enough off-road as long as the driving surface is nothing more challenging than well-maintained gravel or dirt tracks in dry weather, and you’re not planning a rough-and-tumble expedition into remote bushland.

As I mentioned earlier, the great thing about adventures is that you can scale them to suit you and your vehicle and the allroad offers a nice stepping-stone for people who’d like to experience the outdoorsy lifestyle, before perhaps diving deeper into it.

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 You'll never need petrol again, which makes a hybrid seem outdated.

The allroad’s overall look is part of a range-wide refresh and it certainly fits in with the line-up’s updated aesthetic.

Because I’m a bloke who spends the bulk of my time in 4WDs – traditionally bulkier vehicles rather than slim city-friendly wagons – I’m not totally enamoured of the Audi’s style, especially in terms of trip-packing practicality. However, I can certainly appreciate the appeal of its quite low, sleek and streamlined appearance, which its tweaked chunkier grille adds some gravitas to. It’s just not my cup o’ tea.

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.

I’ll answer that question as a politician would – without actually answering the question.

The allroad’s interior looks good and certainly feels open and spacious, although the driver’s seat tends to feel a bit more snug as the dash is angled towards that position.

The new 10.1-inch touchscreen, home for most upfront functions, dominates the dash, in a good way.

The front seats are electrically adjustable with lumbar and driver memory.

There are plenty of places in which to put your everyday bits and pieces (including a decent storage bin/arm-rest), as well as charging points, including two USB ports, for your devices.

Need somewhere to put a cold beverage, mate? There are two cup-holders between driver and front-seat passenger, two in the fold-down centre arm-rest for the back-seat passengers, and bottle holders in all doors.

Back-seat passengers also get air vents, climate control, mesh seat-back pockets and grab handles. 

There is a 495-litre cargo space when the rear seats are in use, but that increases to 1495 litres when those seats – 40:20:40 split folding – are stowed away in the floor.

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...

The Audi A4 all road 40 TDI quattro S Tronic has a 2.0-litre, four-cylinder turbo-diesel engine, producing 140kw at 3800-4200rpm and 400Nm at 1750-3000rpm.

It has a seven-speed S tronic automatic transmission and all wheel drive.

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.

It has claimed fuel consumption of 5.2L/100km (combined), but we recorded actual fuel consumption on test of 8.4L/100km – driving in soft sand likely negatively impacted that figure.

It has a 61-litre fuel tank.

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.

For a bloke who spends a lot of time in big, tall and bulky 4WDs, I felt like I was driving a go-kart. It’s that low, but it’s also that much fun – and it’s a very different driving experience to what I’m used to.

The allroad is 4762mm long, 1847mm wide and 1430mm high, and has a listed kerb weight of 1720kg. So relative to the 4WDs I usually steer around, this is light and low slung. It’s more car than SUV, that’s for sure.

Acceleration is rather punchy (the engine and auto are a decent match-up), steering is light but precise, and you can cycle through drive modes (efficiency, comfort, auto etc) to set up vehicle characteristics to suit your driving style and conditions.

The quattro all-wheel drive system helps to keep the allroad planted and composed at all times. 

Ride is on the sharpish side of firm and you do tend to feel every irregularity in the road surface – it is long and low and on low-profile rubber afterall.

The virtual cockpit plus – a 12.3-inch high-resolution colour display – offers a comprehensive read on all things to do with the allroad.

Throw around your superlative of choice – “sporty” and “dynamic” fit this allroad well – but I’m loathe to gush about its on-road performance much more than that because I reckon if any motoring journos are reading this – many of whom spend the lion’s share of their time swanning about in sports cars – they would have already choke-spat out their dirty chai with surprise by now.

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.

This Audi has a three-year/unlimited km warranty. Service intervals are recommended every 12 months or 15,000 km, whichever comes first.

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.
