Holden Commodore vs Alfa Romeo Giulietta

What's the difference?

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 much right and some things not quite right – the Giulietta has the Alfa Romeo mix of highs and lows which the brand is famous for. There’s no mistaking that this is a unique and sexy looking car, with the practicality of a five-door hatch plus impressive handling and performance.  More heart than head decision here though it seems, but romantic Alfa enthusiasts should adore it.

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. 

Alfa Romeo couldn't design a boring car even if it was handed a picture of a Toyota Camry and told to copy it or else. The Giulietta is no exception.

There's the deep 'V' grille shared with the new Giulia sedan and 4C sports cars that make up the current Alfa model line-up. There's the bug-eye headlights with pretty inset LEDs and the chiselled bonnet, a side profile which looks like that of a mini Porsche Cayenne and a cute-but-tough bottom with its elegant taillights and twin exhausts.

The latest update brought a honeycomb mesh grille and a slightly different design to the headlight and LED foglight surrounds. The tail pipes were also given a styling tweak, so too were the alloy wheels.

Despite its coupe looks it's actually a five-door hatch with ‘hidden' handles for the rear doors.

The cabin saw new materials and finishes added. The Veloce had the Alfa Romeo logo stitched into the integrated headrests, shiny sports pedals, and lashings of faux carbon fibre trim on the doors and dash.

You can tell a Veloce from the outside by the red Brembo brake calipers behind the front wheels, 18-inch alloys, its chunkier exhaust tips poking out of the diffuser, red pin-striping to the front and rear bumpers, and the black window surrounds.

Okay, how big or small is it? Here's some dimensions for you. The Guilietta is 4351mm long, 1798mm wide, 1465mm tall and the Veloce with its sports suspension is 9mm lower than the others with 102mm of ground clearance.

Compared to say a Mazda3 hatch the Giulietta is 109mm shorter end-to-end and only 3mm wider. But if you're considering an Giulietta why are you looking at the Mazda3 anyway? That would be sensible - Like comparing Cancer Council hats to top hats.

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.

Beautiful things tend to favour form over function. The Giuletta tries to do both and succeeds…but also fails in places.

Successes first: despite its coupe looks it's actually a five-door hatch with ‘hidden' handles for the rear doors placed up at window level near the C-pillar. So good is the two-door disguise that our photographer climbed into the back seat through the front door.

Rear legroom is a bit tight back there and at 191cm I can sit behind my driving position but I'd hate for me to be sitting behind me because my knees are digging hard into the seat back.

Headroom isn't much chop either and I literally can't sit in the back seat and hold my head high – a combination of that sloping roofline and the optional double sunroof reduces the head space.

A major practicality fail is the lack of storage throughout the cabin.

Ordering drive-thru is possibly out of the question.

My wife's phone kept mysteriously appearing in the footwell every time we left it in the glove box, like there was a tear in the time-space fabric, but then we realised it was slipping through a gap.

There's no centre armrest storage bin in the front – actually there's no centre armrest. There is a pop-up hidey-hole on the dash but with only enough room for a pair of sunglasses.

The two cup holders in the front are small. It's safe to say that unless you have somebody with hands at the ready, ordering drive-thru is possibly out of the question.

Or if you have long arms and can reach the fold down armrest in the back there are two decent sized cup holders along with a small storage space. There are no bottle holders any of the doors, but there is fortunately room for a phone and wallet because there isn't space for them anywhere else.

But wait, the Giulietta is saved from a total storage fail by a large-for-the-class 350-litre boot. That's 70 litres bigger than a Toyota Corolla's and only 14 litres less than the Mazda3.  We could fit the pram, the shopping and the rest of the gear which goes with a military operation such as a trip to the park with a toddler in there.

The 2016 update saw the Giulietta variants renamed. There's the entry grade $29,990 Super Manual which has a six-speed manual gearbox, then buyers can step up to the Super TCT with a six-speed dual clutch automatic transmission for $34,900 and then there's our test car – the Veloce for $41,990. There's 10 paint colours at your disposal from the colour of our car (Alfa Red) to Perla Moonlight. Only Alfa White comes at no extra cost, the rest are a $500 option.

The Veloce collects the same features as the Super TCT such as a 6.5-inch touch screen, with sat nav, front and rear parking sensors, three drive modes and then adds bi-xenon headlights, 18-inch alloys, leather and Alcantara seats, a flat-bottomed steering wheel, the big exhaust tips and the sports diffuser, tinted rear glass and then less cosmetic features such as sports suspension and launch control.

There's no reversing camera which is disappointing, considering they come standard on some cars half the price.

At this price you'd shop the Veloce against a BMW 120i hatch for $41,900, a Volkswagen Golf GTI for $43,490 or possibly a high-end Mazda3 SP 25 Astina for $37,040.

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.

The Giulietta Veloce has a 1.75-litre four-cylinder turbo-petrol engine which produce 177kW of power and 340Nm of torque. It's a great engine that lets loose a wonderful scream when pushed hard and the little grunts it makes when it changes gear when driving around normally sound like a giant enjoying his food.

The transmission is a dual-clutch auto which Alfa calls a TCT or twin-clutch transmission. I'm not a fan of them regardless of the brand of car they're in but the Alfa version is better than most of the others in its smoothness at lower speeds and decisiveness.

There's so much potential here for a great driving experience.

What about the Giulietta's reliability over time? This version of the car is less than two months old so we can only comment on what it offers as a brand-new vehicle, but you'll find good context in our used review of the earlier 2011-2014 Giulietta.

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. 

Alfa Romeo says you should see your Veloce drink at a rate of 6.8L/100km during combined driving, but the dash showed more than double that during mainly urban driving while  channelling  Enzo Ferrari.

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.

There's so much potential here for a great driving experience such as the accurate and direct steering and great suspension which provides a comfortable ride and great handling, only for all to be let down by turbo lag which kills the responsiveness in the car.

Of the three steering modes: Dynamic, Natural and All Weather, the Dynamic setting was kept on almost always with the other two just feeling too lethargic.

The Giulietta is front-wheel drive and there's a lot of torque being sent to those wheels, but unlike a stack of Alfas in the past there's next to no torque steer. That said, our hill start test on a wet night saw those front wheels scrambling for traction as it accelerated up the slope. Cornering grip from the tyres is excellent, however.

There's some Alfa Romeo ergonomic issues in the cabin we've gotten used to over the years, but just because you're accustomed to something doesn't mean it's okay. For example, the cramped driver's footwell with the brake and accelerator pedals so close that it's easy to hit both at the same time.

Such is the intensity of the spray from both the window washer and the headlight washers it's like you're captaining a fishing trawler that's hit a massive wave at sea.

The indicator and wiper stalks are also so far from the steering wheel rim that they're almost out of reach – I don't think I have small hands, nobody's ever pointed them out or laughed at them.

And speaking of wipers, the Giulietta is obsessed with keeping itself clean. Pull the wiper stalk towards you to clean the windows and such is the intensity of the spray from both the window washer and the headlight washers it's like you're captaining a fishing trawler that's hit a massive wave at sea. Put the car into reverse and the rear wiper starts squirting and washing.

For Christmas I want Alfa to upgrade their media unit or bin it – the UConnect system disconnected my phone without prompting and isn't intuitive to use.

The Alfa Romeo Giulietta has been given the maximum five-star ANCAP rating. It doesn't have the advanced safety technology such as AEB and lane keeping assistance which is now standard on any small hatches for a lot less money.

For child and baby seats there's two top tether and two ISIOFIX points in the back seat.

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.

The Giulietta is covered by Alfa Romeo's three year/150,000km warranty. Servicing is recommended at 12month/15,000km intervals with a major service every two years. Alfa Romeo doesn't have capped price servicing but there is Mopar Vehicle Protection which customers can purchase with the vehicle for $1995.
