BMW M135i vs BMW 330e

What's the difference?

To answer the question of whether it matters that the new 1 Series is no longer rear-wheel drive, I say no it doesn’t. It may not be as romantic on the absolute limit, but it is better in every measurable way, and still feels distinctly BMW despite moving to the conventional layout of its rivals. 

Be sure to check out Mal’s video review from the 1 Series launch last December:

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 You'll never need petrol again, which makes a hybrid seem outdated.

Yes, that kidney grille is rather large. If you want everyone to know you drive a BMW, you’ll love it. If not, get used to it. The X7, recent 7 Series update and upcoming 4 Series suggest they’re only going to get bigger. 

Nose aside, the 1 Series hatch has always had a distinctive, long-bonnet profile, which has generally been attributed to the rear-drive layout. Despite the move to a transverse engine, the new one is actually very close in proportions when compared side by side.

It’s just 5mm shorter in overall length and 13mm taller, with body width being the most notable change at 34mm wider. 

The key difference is that the front and rear wheels have been moved further back into the body, because of said engine layout change, and to make more back seat space in the rear.

Surprisingly for a model aimed at a younger demographic, the new 1 Series interior design isn’t quite the same step forward as the recent G20 3 Series.

It’s a cut above the X1 and X2 SUVS the new 1 Series shares its underpinnings with in terms of the shapes used, but is still classic understated BMW. 

However its headline act is the Live Cockpit driver display on both models, which gives you fully digital instrumentation and replaces traditional analogue gauges once and for all.

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.

With my modest 172 cm height, I never had any trouble with the old model, but the new 1 Series is a bit more more spacious by all the important measures.

The back seat base and backrest are a bit flat though, which is probably to help the backrest fold almost flat, but probably not very supportive during hard cornering.

There's also no centre armrest in the back or cup holders, but you do get bottle holders in the doors.

You also get two ISOFIX child seat mounts and there’s two USB-C charge points in the back of the centre console, but there's no directional air vents unless you opt for the dual-zone climate control that comes standard with the M135i. 

The boot has grown by 20-litres to a pretty impressive 380 litres VDA which includes a very useful cavity under the floor instead of a spare tyre. An inflation kit is there for those duties. With the back seat folded flat, boot space expands to 1200 litres VDA. 

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...

Both cars use versions of the three and four cylinder petrol engines from before, with the popularity of automatics leaving the previous manual option consigned to history.  The 118i’s 1.5-litre turbo three cylinder now produces 103kW/220Nm, with max torque available all the way from 1480-4200rpm. The 118i now uses the seven-speed dual clutch automatic transmission, as seen on Mini models that use the same engine. 

The M135i’s 2.0-litre turbo has been tweaked to take the place of the six-cylinder M140i from the last model and now produces 225kW/450Nm, with max torque available all the way from 1750-4500rpm. Its auto remains a torque converter though, but now the transverse-mounted unit also shared with Mini models with the same engine and splitting drive to all four wheels via the xDrive system for the first time. The drive split is constantly variable, but the rear bias tops out at 50 per cent and the only limited slip diff is an electric unit on the front 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.

Official combined fuel consumption is a decent 5.9L/100km with the 118i, but the M135i steps up to 7.5L/100km) 2.0 litre four in the m135i. Both engines require premium unleaded. 

Fuel tank sizes vary across the two models also, with the 118i measuring 42 litres and the M135i managing 50 litres, despite its need to package rear drive components somewhere under there also. 

This results in a decent theoretical range between fills of 711km for the 118i and 666km for the M135i. 

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 brand with a marketing slogan of pure driving pleasure, this is the important part, particularly given the new 1 Series has lost its rear wheel drive USP. 

Why do some of us love rear wheel drive? It tends to be more fun when you're driving on the limit, and generally makes for nicer steering because you're only using the front wheels to turn corners.

So how does the new 1 Series drive? That depends on which version. 

The 118i is quite a nice package really. It rides a bit more gently than what I remember in the A-Class and generally feels more like a premium product. It also feels a step ahead of the 2 Series Active Tourer it shares its underpinnings with, which is a good thing.

The three-cylinder engine is quite smooth for a fundamentally unbalanced triple, and it makes enough power to get you out of trouble. 

Do you miss rear wheel drive? Not really, as you can only tell the difference when you're going real fast, which let's face it, is not somewhere 118i drivers are likely to go very often. 

The M135i is a vastly different beast, as you'd expect. Aside from being real quick, it's that much tighter everywhere, but still definitely on the more comfortable side than what we expect the future full house M version to be.

The continuously variable xDrive all-wheel drive system does a great job of putting its power down, but the rear bias maxes out at 50 per cent, which is probably spot on for chasing lap times, but means you miss out on the tailiness of the old one altogether. 

So it’s not as classically fun as the old M140i, but it’s easily faster, and that's what will probably matter most to most buyers. 

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.

BMW is yet to step up to the five year warranty offered by most mainstream brands and now Mercedes-Benz and Genesis, continuing with the three year/unlimited coverage matched by Audi. 

As always, BMW describes the service intervals as condition based, and the car will alert the driver when a service is due. This will occur at least every 12 months though, but individual intervals will vary based on how the car is driven. 

This can all be bundled into five year/80,000km service packs though, with the Basic pack costing $1465, but the Plus pack adds brake pad and disc replacement to regular fluids and consumables for $3790. Assuming 12 month intervals, these prices are about average for a premium branded product. 

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.
