BMW 4 Series vs Holden Commodore

What's the difference?

The BMW M440i xDrive Gran Coupe manages to combine sleek design with a fun-to-drive personality and surprising practicality. It’s a rapid premium, four-door, five-seater offering extra flair, and in this part of the market, good value. But more than anything else it’s got a cracking in-line six under the bonnet.

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:

So, how does this four-door 4 Series differ from a four-door 3 Series? The answer is as plain as the nose on this car’s face.

BMW’s head of design, Adrian van Hooydonk, has been expanding the brand’s signature ‘kidney grille’ in every conceivable direction, and this is the much talked about interpretation adorning all 4 Series models (petrol, hybrid and electric) as well as the M3 sedan.

The new Gran Coupe is longer, wider, and taller than the outgoing model, and the track is broader, front and rear. The wheelbase has also been extended, now a whole 5.0mm longer than the 3 Series.

The DRLs and headlight main beams are LED with laser high beams, immense gills square up the edges of the front clip, while a vent and the strake attached to it stand the car apart. Plus, of course, the doors are frameless. 

One niggle, though. I’m not in love with the slender door handles. It’s hard to get a good grip on them, especially in the wet. 

Standard 19-inch alloy rims are shod with Pirelli P Zero rubber 245/40 fr / 255/40 rr), the roofline slopes distinctly towards the rear, a lip spoiler on the trailing edge of the tailgate is classic BMW, darkened LED tail-lights wrap around the rear corner, and a diffuser-type panel is flanked by large exhaust apertures.

Our car’s ‘Aventurine Red’ finish is a $3850 option, but to my eyes anyway it looks superb.

Exterior trim including the grille frame, front air intake inserts, mirror upper housing, model designation badges, and tailpipe are finished in ‘Cerium Grey’, which I reckon 99.9 per cent of people will see as black. 

The interior will be familiar territory for any current BMW owner, the 12.3-inch digital instrument screen sitting in a compact, hooded binnacle, and partnering with a 10.25-inch multimedia display standing proud of the dash above the broad centre stack. 

The seats are trimmed in top-shelf leather with blue contrast stitching, plus the grippy sports wheel is also wrapped in genuine hide.

BMW calls the finish on the main buttons and controls ‘Galvanic’ which translates to a slick silver metallic look and feel. Configurable ambient interior lighting is a nice touch, and the broad console enhances the driver-focused feel, with a sprinkling of carbon-fibre around the centre console and dash lifting the sense of occasion.

Overall, the interior feels clean and classy with an obvious attention to detail.  

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. 

At close to 4.8m long the 4 Series Gran Coupe is a sizeable machine. Up front, the feeling is airy and comfortable, and the rear is surprisingly spacious, especially in light of the car's sloping roofline.

At 183cm I have to fold myself tightly to fit under the low roof, but once inside I have enough room to sit behind the driver’s seat set for my position with more than enough legroom and adequate headroom. Put three full-size adults across the back row, though, and there will be breathing difficulties.

Kids will be fine, however, and individual vents with adjustable temp in the rear was a big plus during a particularly hot test week.

For storage there are generous door bins in the front with room for large bottles, a decent glove box, dual cupholders in the centre console, a reasonable lidded bin (which doubles as a centre armrest), and the wireless device charging bay (forward of the gearshift) makes a handy oddments space when not in use.

In the rear, again the doors feature pockets with room for (medium-size) bottles, there’s a fold down centre armrest with two cupholders, but thanks to the one-piece shells on our test car’s optional M Sport front seats there are no map pockets.

Power and connectivity runs to a USB-A socket and a 12V outlet in the front centre console, as well a USB-C port in the front storage bin, a pair of USB-Cs in the rear, and a 12V outlet in the boot.

Speaking of which, lift the tailgate and with the rear seat upright we were able to fit all three of our suitcases or the beefy CarsGuide pram into the healthy 470-litre (VDA) boot space.

Lower the 40/20/40 split-folding rear seat down and 1290 litres of volume is at your disposal. Plus there are handy bag hooks and tie-down anchors to help secure loose loads.

You can also tow a braked trailer up to 1.8 tonnes (750kg unbraked), but don’t bother looking for a spare of any description, a repair/inflator kit is your only option.

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. 

Under the bonnet is BMW’s (B58) all-alloy 3.0-litre twin-scroll turbo intercooled, in-line six-cylinder engine, driving all four wheels via an eight-speed automatic transmission and electronically controlled clutch pack, as well as an electronic limited-slip differential at the rear.

It features high-pressure direct-injection and BMW’s ‘Valvetronic’ system managing air flow to the intake side, to produce 285kW at a relatively high 5800-6500rpm. But the big punch is 500Nm of peak torque from just 1900rpm all the way to 5000rpm.

The M440i is also a mild-hybrid with a 48-volt starter motor-generator and supplementary battery able to give an 8.0kW kick at low engine speeds.

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.

MORE: If any Commodore engine problems or automatic transmission problems crop up, you’ll likely find them here.

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.

BMW’s official fuel economy figure for the M440i xDrive Gran Coupe, on the ADR 81/02 - urban, extra-urban cycle, is 8.2L/100km, the 3.0-litre turbo six-cylinder emitting 187g/km of C02 in the process.

Stop/start is standard, and we saw an average of 11.1L/100km over city, B-road and freeway running during a week with the car.

With the 59-litre tank brimmed (with minimum 95RON premium unleaded) that real-world test number translates to a range of around 530km.  

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. 

BMW says the M440i xDrive Gran Coupe will accelerate from 0-100km/h in 4.7sec, and I reckon the threshold for a properly quick car is sub-five seconds.

The 3.0-litre turbo six develops its peak power of 285kW between a relatively lofty 5800-6500rpm, but the big number is a solid 500Nm punch of pulling power delivered between 1900-5000rpm.

Squeeze the throttle pedal pretty much anywhere in the rev range and the response is glorious. Rapid acceleration accompanied by raucous engine noise and rorty exhaust note (albeit with some synthetic support). Various pops and bangs in the Sport settings add extra entertainment.. 

The eight-speed auto gets some electric support from the mild-hybrid system to fill the torque gap on up shifts, and the result is a conventional torque-converter transmission that behaves like a dual-clutch.

Shifts are seamless in general driving, and satisfyingly quick in a more aggressive mode, the wheel-mounted paddles dialing up the fun in manual changes. 

Suspension is double wishbone front and multi-link rear with the standard ‘Adaptive M Suspension’ built around an adaptive damper set-up.

The change between the ‘Comfort’ setting to the ‘Sport’ or ‘Sport+’ calibration is close to instant and makes a discernible difference, especially in terms of ride comfort.

I found the best ‘Individual Sport’ arrangement to be damping in Comfort, with the steering engine and transmission in Sport. The car flows so beautifully through corners with urgent response from the powertrain.

By all means dial up the suspension if you’re having a real crack, but the car feels superbly balanced, stable and predictable in Comfort (front to rear weight distribution is 50:50).

The electrically-assisted variable-ratio steering is nicely weighted with good road feel, and the grippy sports steering wheel is a nice point of contact.

The xDrive AWD system’s default setting is rear-biased, although it will push most of the drive forward when required. But the RWD feel is unmistakable. 

The M440i weighs in at around 1.9 tonnes but feels lighter and more nimble than that figure would typically indicate.  

A standard electronically-controlled M Sport limited-slip differential puts the power down confidently. I have a favourite LSD test corner on my regular evaluation drive, a sharply twisting and rising left-hander.

Rolling into it in a low gear before planting the throttle mid-corner, the car simply hunkers down without a hint of fuss (or traction loss) as it rockets out the other side.

Optional M Sport front seats ($2000) provide comfort and firm location in equal measure and in terms of ergonomics BMW knows how to focus on the driver and set-up an efficient environment. Key controls are perfectly positioned and simple to operate.

I have an issue with the ‘Lane Departure Warning’ function, however, which is too quick to intervene and overly intrusive when it does so. I turned the ‘Steering Intervention’ function off. You can dial down steering wheel vibration warnings, too.

The standard M Sport brakes feature big vented rotors front and rear, with fixed four-piston front calipers doing the bulk of the work. They’re strong but don’t bite or release too aggressively. It’s easy to grease in a smooth application. 

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.

The M440i Gran Coupe is covered by BMW’s three-year/unlimited km warranty (including paintwork), as well as 12-year/unlimited km anti-corrosion (perforation) cover. 

That’s off the premium market pace now with Genesis, Jaguar, and Mercedes-Benz at five years/unlimited km and Lexus set to join them from January 1st, 2022. 

That said, roadside assistance is provided for the duration of the main warranty, but it’s worth noting “rattles and squeaks” are only covered for one year.

Service is condition-based, the car telling you when maintenance is required, and a range of service packages are available. The basic plan covering a 4 Series for five years/80,000km comes in at $1750. 

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.
