BMW I4 vs Holden Commodore

What's the difference?

If you’re intimidated by the electric future, don't be, because BMW’s i4 is just as good as any non-M sedan BMW offers right now.

The i4 delivers all the things you love about a 3 Series, engaging driving dynamics, a well-appointed interior and comfortable ride, but its all-electric powertrain means you’ll never have to stop at a servo again.

With a large battery on board, the i4 also serves up a decent driving range that should put anxiety-prone EV drivers at ease.

That is, of course, if you can get onboard with the looks.

So will the new Commodore become Australia's favourite car? I strongly doubt it, but it's not the car's fault, and it wouldn't be any different if it was a rear-wheel drive, V8, Australian-built sedan. Australian buying habits have just moved on, and diversified into a range of SUVs, small hatches and dual-cab utes. 

Taken as an all-new entry in Holden's revitalised line-up though, the new Commodore ticks all the important boxes required of a mid-size to large passenger car these days. It may not be anywhere near as exciting as a 6.2-litre Redline sedan, ute or wagon, but it’s objectively a far better car overall, and you should definitely give it a drive before dismissing it. 

The pick of the bunch in my eyes is the $39,490 RS Sportwagon with the 2.0-litre petrol engine. Yep, the best new Commodore is now a four-cylinder station wagon.   

Be sure to check out what James Cleary thought of the new Commodore in prototype guise here:

If the i4 looks familiar, that’s because it is based on the 4 Series Gran Coupe that entered showrooms last year.

This means a four-door liftback body style with a sloping roofline, athletic proportions and sizing close to the Tesla Model 3 and Polestar 2.

Let’s get it out of the way early and talk about the elephant in the room, the oversized front grille.

Say whatever you want about it, there’s no denying it gives the i4 a unique and head-turning look, and in my opinion, it’s not too bad.

In the flesh, it really isn’t as big as the press photos have made it out to be, and with the front numberplate to split it up, it does start to look a bit more like a traditional grille.

In profile, the 19-inch wheels fill out the arches well, and hide the massive brakes that add to the i4’s sporty appearance.

I particularly like the almost flush door handles that look futuristic, but aren’t as pretentious as those retractable handles you see on Teslas and Range Rovers.

Slim tail-lights and a chunky bumper inform the styling of the i4’s rear, but we’re really not a fan of a rear diffuser that keeps the exhaust cut-outs.

It makes sense on a model like the 4 Series Gran Coupe, but it just looks look rather odd on an all-electric model like the i4.

While the outside of the i4 might be all about that big grille, the inside is all about big screens, two of them in fact.

The instrumentation and multimedia screens dominate the experience inside, but BMW has also included physical buttons on the steering wheel and centre stack, as well as a rotary control knob, to make navigating the menus that much easier.

The connected screens differentiate the i4 from its 4 Series Gran Coupe relative, and make the cabin feel futuristic and befitting of the all-electric powertrain.

Overall, the i4’s styling might not be to everyone’s tastes, but BMW definitely gets credit for being bold in its aesthetic choices.

Would have been nice to see BMW’s designers go a bit further in differentiating the i4 from its 4 Series Gran Coupe cousin, but there's no denying the head-turning appeal of this all-electric sedan.

Aside from the move to a front-drive basis, the other key difference between the new Commodore and those of the past is its shift from a classic three-box sedan shape to a sleek, five-door Liftback. Even the Sportwagon has an elegant arc to its roofline, which is arguably their most appealing design element. There are no Ute or Caprice bodystyles, and there never will be. 

The European-designed look is less macho than the bulging wheelarches of the VE and VF, but more in line with its European rivals like the Ford Mondeo, Volkswagen Passat and Skoda Superb. 

The best way to identify specific models is by their wheels, with the trim levels split between a more elegant body trim on the entry, Calais, Calais-V and Tourer variants, and sportier body kits with side skirts and a rear spoiler on the RS, RS-V and VXR flagship.

The interior look is also best described as elegant, with fresh shapes that flow cohesively into the door trims and centre console. There’s a general air of quality about it, but it’s let down by some cheap-feeling controls and switches, particularly the climate control knobs. 

The ZB’s overall size is bigger than you might think, with most dimensions fitting neatly between the VE/VF and the VT-VZ generation that preceded it. 

You might be surprised to learn it’s no lightweight either, with the heaviest Calais-V Tourer actually outweighing the portliest VF by 31kg. 

Interior dimensions are comparable with its predecessor, with the most significant differences being a narrower back seat thanks to its 36mm thinner body and 13mm less rear headroom in the Liftback (but 3mm more in the wagon).  

Before the decision was made to source the new car from Germany, Holden was planning a longer wheelbase for Australia. One specific requirement that did reach fruition is the availability of a V6 engine, which isn’t fitted to European versions.

Under the skin it rides on GM’s E2XX platform, which is a significant evolution of the chassis that underpinned the previous Insignia and the now-defunct Holden Malibu. 

Aside from having a say in every step of its design process, Holden engineers covered more than 200,000 kilometres of testing on Australian roads and at the Lang Lang proving ground.

This has been to fine tune the drivetrain calibrations, the steering, suspension, and even details like the sat nav and radio reception to suit our tastes and unique demands. 

Specific suspension tunes have been developed for four cylinder models, the V6 Calais, V6 RS-V and the Tourer, with unique setups between Liftback and Sportwagon bodies. 

The only version not to score an Australian suspension tune is the VXR, which was treated to a performance-focused setup at the Nürburgring in Germany. 

As a premium mid-sized sedan, the BMW i4 offers up enough storage and space for most, but keep in mind there are limitations.

From the driver’s seat, everything is well placed and the electronically adjustable seats offer plenty of adjustability to get comfy for long road trips.

Storage options include an central cubby, glove box, two cupholders and small door pockets that just about fit a bottle, but the design means it rattles around a little.

Speaking of fiddly, between this car, and the weird plastic cowl thing found in the Z4 and 1 Series, BMW needs to be called out for some of the most annoying wireless smartphone charger designs.

This one is tucked all the way under a retractable lid, and is barely wide enough to fit some flagship-sized phones.

However, we will give BMW huge props for its iDrive8 multimedia system, which is displayed on a huge 14.9-inch screen.

The menus are clear, concise and intuitive, while the software is buttery smooth and responsive. It feels snappier than some phones we’ve used in the past.

Credit too for not making all inputs touch, as there is a rotary control knob and voice command capability available.

In the second row, things are a little more cramped, but at 183cm tall I can fit in the outboard seats with tight headroom.

There’s enough leg and shoulder-room, too, and passengers can make use of the climate controls, USB-C charging ports and a fold-down-centre armrest with two cupholders.

Opening the boot reveals 470 litres of volume, but fold the rear seats down and that pace swells to 1290L.

Loading large and bulky items is made much easier thanks to the liftback design, and it’s important to note i4 buyers aren't penalised in terms of practicality as the i4 and 4 Series Gran Coupe share the same boot capacity.

However, the charging cables can get in the way, as there isn’t any dedicated space for them.

The charging point is also in an annoying spot, in the right-rear fender where the petrol cap would be.

It means that you always have to reverse into charging spots, and it can be tricky to manoeuvre the i4 into just the right position to get the charging cable to reach.

The Nissan Leaf's front centre charging port, or the dual charging ports available on the left and right fenders in the Audi e-tron or Porsche Taycan are preferable.

Another traditional Commodore trait to have taken a step backwards is its ability to carry three adults across the back seat. Admittedly only really an issue for taxi use, the ZB will certainly still swallow three, and likely three child seats, but less comfortably and more like the similarly sized Camry.

The Liftback’s reduced headroom didn’t matter for this 172cm tester, but if you were marginal in a VF you’d probably want to avoid spiking your hair.  

The cabin ticks all the other important boxes for a modern family car, including twin cupholders front and rear, bottleholders in each door and two ISOFIX child seat mounts in the rear. 

All get a good cluster of USB and 12V charge points, while the RS-V models upwards get a big bonus with wireless phone charging. 

The Liftback's boot space is only slightly down on before at 490 litres, but the huge opening created by the five-door design is so much more useful in the real world. It also brings a split-fold back seat for the first time in a non-wagon Commodore. 

The Sportwagon has lost around 100 litres in capacity though, but is still a very useful 560 litres to seat height or 793 litres to the roof. 

Holden’s local team has also developed a range of optional accessories for the Commodore, which includes a bonnet protector, weather shield, towbar, boot liner, floor mats, headlight protectors, sill guards, locking wheel nuts, roof racks and a cargo net, but there’s no sign of a cargo barrier, nudge bar or bullbar at this stage.

Aligning with the Insignia’s European platform has bumped the Commodore right up to speed with the current status quo of features expected in such a family car. 

Available Commodore firsts include standard auto emergency braking (AEB) on all models, adaptive cruise control, 360-degree / surround-view cameras, massage and ventilated seats, heated rear seats, wireless phone charging, LED headlights and a power tailgate on the wagons. Like most new cars, there’s no more CD player or DVD player with the radio and other multimedia options. 

The broad model range is split into LT, RS, RS-V, Calais, Calais-V, VXR trim levels, while the off-road flavoured Tourer is split into Calais and Calais-V versions. 

All bar the Tourer and VXR are available with either Liftback or Sportwagon ($2200 extra) bodystyles, while the 2.0-litre turbo engine is standard in the LT, RS and Calais. The V6 with all-wheel drive is available in the RS, RS-V, Calais-V, VXR and both Tourer trims, while the diesel engine is limited to the LT and Calais. 

The base LT Liftback drops the Commodore entry point by $1800 with a list price of $33,690. The diesel engine is available in either bodystyle for an extra $3000. 

Standard features include the aforementioned AEB, lane keep assist, lane departure warning, Apple CarPlay and Android Auto in addition to Bluetooth connectivity with a 7.0-inch multimedia screen, reversing camera, auto parking, a leather steering wheel, an eight-way power driver’s seat, proximity keys, auto headlights and wipers, air conditioning and 17-inch alloy rims.

The RS kicks off at $37,290, or $40,790 in V6 AWD guise, and brings sports front seats, steering wheel and body kit, blind-spot monitoring, rear cross-traffic alert and bigger 18-inch alloys, while the Sportwagon version gets a power tailgate. 

The V6 AWD RS-V commands $46,990, and adds leather seats, heated front seats, paddle shifters a larger 8.0-inch multimedia screen with built-in GPS navigation system and DAB+ digital radio, a colour head-up display, wireless phone charger, interior ambient lighting, upgraded Hi Per strut suspension and a sportier rear bumper. 

The $40,990 Calais is also available with the diesel engine for an extra $3000, or as the V6 AWD Tourer wagon for $45,990. 

The Calais sits closer to the LT on features, but adds leather trim, front seat heaters, 8-inch multimedia screen with built-in GPS navigation system and DAB+ digital radio, wireless phone charging, blind-spot monitoring, rear cross-traffic alert and 18-inch alloys. 

The Calais Tourer scores a ride height lift (overall height up 42mm) and off-road styled unpainted wheel-arch moulds and bumper caps. 

The $51,990 Calais-V adds a Bose premium sound system, ventilated front seats, a massage function and powered side bolsters for the driver’s seat, heated rear seats, a sports steering wheel with paddle shifters, 360 degree cameras, colour head-up display, adaptive LED headlights and 20-inch alloys. The Liftback version gets an electronic sunroof, while the Tourer version gets a panoramic glass roof. 

The top-spec VXR is closest to the RS-V in terms of features, but for $55,990 it adds VXR-specific sports seats with power adjustable bolsters and ventilation up front, heated rear seats, Bose premium audio, adaptive suspension, adaptive cruise control, Brembo brakes, VXR floor mats and sill plates, active LED headlights, 360-degree camera, electric sunroof, and 20-inch alloy wheels. 

From launch, Holden is offering drive-away pricing across several models, with on-road costs included. The LT petrol Liftback is available for $35,990, while the RS Liftaback is being offered for $38,990 with the 2.0-litre turbo and $42,490 with the V6. The Calais Tourer is also being offered for $47,990 drive away.

The available colours are spread across two whites, two reds, silver, grey, black and blue, with some only available on certain models. All bar the non-metallic white and red will cost you an extra $550, but there’s no sign of the green, purple, orange, or yellow we’ve seen over the past decade. 

If there’s one thing BMW knows how to do well, it’s building a sports sedan like no other. And that holds true for its EVs.

Powering this i4 eDrive40 is a single electric motor that produces 250kW/430Nm, which beats the outputs of even the 330i and 430i Gran Coupe.

With drive sent to the rear wheels, the i4 eDrive40 can accelerate from 0-100km/h in just 5.7 seconds, beating out the aforementioned 330i and 430i models.

For those that want a bit more pep, the top-spec M50 grade’s dual-motor set-up punches out 400kW/795Nm for a lightning quick 3.9s 0-100km/h run.

Compared with its petrol-powered 4 Series Gran Coupe counterpart, the i4 certainly puts up respectable figures, while offering more than a performance match for the Polestar 2 and Tesla Model 3.

No, there’s no more V8, manual transmission or rear wheel drive, but the ZB’s options are more in sync with its newer rivals. 

For the first time since the VH, or 1984, the base engine is a four-cylinder petrol unit, but uses modern tech like direct injection and a turbo to boost power statistics to more than triple that of the infamous Starfire engine. Also seen in the Equinox, the new turbo motor’s 191kW is also notably 6kW more than the 5.0-litre V8 in the VL Group A SS (Walkinshaw), and 1kW more than the 3.6-litre V6 was making in top-spec VZ Commodores – so pretty good horsepower for its engine size.

The real story is its healthy 350Nm of torque, which is also more than what the same VZs were making, but on tap from a useful 3000-4000rpm.

The latest version of the 3.6-litre Alloytec V6 that’s seen duty in VZ, VE and VF models makes a reappearance as the new performance leader, but mounted sideways and turning all four wheels this time. In ZB trim, it produces 235kW and 381Nm, the latter from 5200rpm.

For the first time, you can also choose a diesel option with LT and Calais trims, which is a version of the engine used in the previous Opel Insignia. You’ll also find it under the bonnet of the Jeep Cherokee and Compass, and its applications spread as wide as the Alfa Romeo 159 that ended production in 2011. In Commodore guise, the turbo 2.0-litre engine specs are 125kW and 400Nm (available from 1750-2500rpm), and therefore taking out the torque trophy for the ZB range. 

Both petrol engines are paired with a nine-speed torque converter automatic transmission, while the diesel has an eight-speed gearbox. Both four-cylinder engines are front-wheel drive, while all V6 variants are all-wheel drive.

The all-wheel drive system is actually quite clever, using what’s called a Twinster twin-clutch rear differential for finite torque vectoring, or sending the just the right amount of power to each wheel. The system varies torque distribution between 100 per cent front and a 50/50 split. 

If you think the Commodore has gone soft, its towing capacity ratings also suggest otherwise, with a 2100kg maximum braked rating for V6 models matching the best offered previously. The four cylinder models are rated at 1800kg, which is 200kg better than what the previous 3.0-litre V6 and LPG models carried.

With an 84kWh battery the official range on this i4 eDrive40 is pegged at 590km when tested to WLTP standards.

However, when fully charged, our test car's range readout was around 390km.

But keep in mind EVs aren’t as effective in cold weather, and the mercury was showing only three degrees on most days during this freezing Irish winter.

Luckily then, BMW has included DC fast-charging capabilities in the i4 as standard, with its 210kW CCS plug able to take the battery from 10 to 80 per cent in around half an hour.

BMW has included DC fast-charging capabilities in the i4 as standard, with its 210kW CCS plug able to take the battery from 10 to 80 per cent in around half an hour.

Using an 11kW AC charger however, will require 8.5 hours for a full charge.

In a week with the car, I averaged an energy consumption rating of 23.4kWh per 100km, almost matching the official figure of 22.2kWh/100km.

My driving included several long-distance trips on the freeway, however, an environment in which an electric vehicle does not excel.

Worth noting the heavier and more energy-hungry M50’s official driving range drops to 510km, but we’re yet to test its real-world figures.

As you’d hope, the ZB sets a new Commodore benchmark for fuel consumption, with the diesel models managing a best official combined figure of 5.6L/100km. The petrol four-cylinder models also pip the VF’s best combined fuel economy figure of 8.3L/100km with 7.4 and 7.6L/100km for the LT, RS and Calais Liftbacks respectively. The Sportwagon versions wear 7.7 and 7.9L/100km figures, while V6 versions span 8.9-9.3L/100km combined ratings. 

It’s worth noting that the petrol four-cylinder engine needs premium 95RON unleaded to do its best, while the V6 is happy to run on regular 91RON unleaded. All versions have a 61.7-litre fuel tank. 

If you came here just to find out whether BMW has succeeded in transplanting its signature sports sedan characteristics into the all-electric i4, the answer is, yes.

The best thing I can say about the i4 is that, aside from the way power is delivered and the lack of engine and exhaust noise, it feels just like a 3 or a 4 Series.

Steering is sharp and responsive, throttle and brake inputs are immediate, making this rear-drive i4 a delight to drive enthusiastically.

The staggered Michelin Pilot Sport 4 tyres and massive brakes obviously help in this regard, and look, it’s not as sharp as the Porsche Taycan, still the sharpest electric vehicle we’ve driven to date, but the driving experience in this i4 is comparable to the excellent 3 Series.

But I’m not in love with the fake sound piped into the cabin when in 'Sport' mode. It sounds weirdly low-rent and I much prefer to accelerate to triple digit speeds in serene, near-silence.

Switch things up to 'Comfort' mode, and the i4 makes for a surprisingly relaxed drive.

The steering gets bit a looser and the adaptive dampers ease off a little, soaking up bumps and road imperfections with minimal affect to occupants.

Pair this with the nearly-silent electric powertrain, and well, our little one in the back seat has fallen asleep on more than one occasion in my time with the car

You can also adjust the level of regenerative braking in the i4 and operate it with one pedal like in the Nissan Leaf and Hyundai Ioniq 5.

This is a more efficient way to drive an EV as it forces you to look ahead and be careful with your throttle inputs.

One-pedal driving might not be for everyone, but it’s nice to have the option there.

The Commodore we know and most of us love is just as famous for its quality driving experience as its local production and motorsport successes. So, the ZB has some big shoes to fill in this area. 

At the ZB’s media launch, we drove everything aside from the base LT or any diesel variant, over several hundred kilometres of pretty much every road condition. 

I’ll cut to the chase. There’s a genuine quality to the way they handle Australian road conditions. We drove them back to back with a UK-spec model at Lang Lang, and while you’d expect the local car to excel at its own test facility, the rear and front suspension work in harmony to handle mid-corner bumps with far greater stability than the alternative. The electric power steering weighting was also lighter, but it didn’t seem to lose any precision. 

You probably wouldn’t notice it driving to the shops every day or cruising on the highway, but this on-limit controllability could easily be the difference between life and death in an emergency. 

The turbo four is a surprisingly capable and refined package, and would honestly be my pick if I were in the market. It’s smoother and more tractable than the V6, so feels like it would deliver speed more readily than the bigger engine unless you were going flat out. 

Holden isn’t quoting official 0-100km/h acceleration figures, but we hear the petrol four is good for a 7.0 second-ish time, and the V6 will manage just over 6.0sec. So there’s really not much in it outright. 

Therefore it’s a shame you can’t get the Tourer with the petrol four, but because the combination is available in Europe, Holden could shift the line-up if there’s enough demand. 

The nine-speed auto does a pretty good job with either engine, and its electronic brain does a slick job of seamlessly adjusting its shift behaviour to your driving style. 

Holden isn’t quoting ground clearance figures, but all have enough to handle dirt roads, and while the 17-inch wheel equipped models match the VF II’s 11.4m turning circle, be aware that the 18-inch wheel variants blow out to 11.7m, the 19s are 12.7m, and Holden doesn’t quote a figure for the 20-inch equipped Calais-V Liftback and VXR.   

The only other surprise among the group we drove is the Calais-V Liftback, which is likely to be a bit too sharp in its ride for some luxury buyers on its big 20-inch alloy wheels. The Calais or one of the Tourers would be your best bet for comfort.  

The VXR performance flagship is a completely different personality to the SS models of the past. It’s nowhere near as fast, but is more of a grownup package that’s easier to get the best out of. 

Its more demure than the brash final VF IIs, and the V6 does make a pretty sweet note, even if half of it is coming from the speakers.

Nothing was ever going to replicate the romance and pride of the last SS, but all is not lost for fans of fast Holdens.

All versions of the new Commodore come with a maximum five star ANCAP safety rating, which has been measured against 2017 standards. The VF’s five star rating was based on 2013 standards.

As mentioned above, all versions get standard AEB and ISOFIX child seat mounts, plus features like lane keep assist and departure warning, auto parking, a reversing camera with front and rear sensors and six airbags covering both rows of seats. 

All versions also get a novel following distance indicator to help you gauge a safe distance from the car in front. This could serve as excellent driver training, and worth having a go with on a test drive.

RS variants upwards get blind-spot monitoring and rear cross-traffic alert, while only the Calais-V and VXR get 360-degree /surround-view camera setups.

Like all BMWs sold in Australia, the i4 comes with a three-year/unlimited kilometre warranty with roadside assist over that period.

This falls short of the now-standard five-year assurance periods offered by premium rivals Audi, Genesis, Jaguar, Lexus and Mercedes-Benz.

Scheduled servicing intervals for the i4 are every 20,000km/24 months, at least in overseas materials.

Australian intervals are yet to be confirmed, but BMW is offering service price plans covering four- and six-year periods in 'Basic' and 'Plus' forms.

The Basic plan for four and six years is set at $1240 and $1765 respectively, while the Plus package is $4805 and $5500.

Holden is currently offering a seven-year, unlimited kilometre warranty with roadside assistance to help boost sales, but be on the lookout for the return of this deal if you miss out this time. Normally, the Commodore carries the standard three year/100,000km warranty. 

Service intervals are now 12month/12,000km, which have shifted from the previous 9month/15,000km terms.

Service costs are capped for the first seven trips to the workshop, with petrol models costing $259, $299, $259, $359, $359, $359 and $259, or a total of $2153 over seven years or 84,000km. The diesel is actually slightly better value at $259, $359, $259, $399, $359 and $399, or $2134 over the same period.
