Holden Commodore vs Mercedes-Benz CLA-Class

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:

The new AMG C 43 may lack the drama and excitement we’ve come to expect from the German performance brand, but that doesn’t mean it’s a bad car. Yes, it could be more extroverted and the ride could be improved, but this is still a sharp-looking sports sedan with loads of punch.

This is a car that speaks to its times, with ever-stricter emissions regulations making it harder and harder for car companies to produce loud, wild and charismatic cars. So Mercedes-AMG has worked within those boundaries and come up with a car that retains at least some of those core elements that has made the brand so desirable over the years.

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. 

Mercedes has created something of a problem for itself with its decision to introduce AMG styling packages for the majority of its range, including the C-Class.

It means the C 43 has to walk a fine line between looking like a unique AMG model, rather than just a C300 with a bodykit and not out-doing the C63.

To that end it has AMG’s now familiar grille with vertical bars, the unique and complex-looking 20-inch alloy rims and a small lip spoiler on the boot. But otherwise it is surprisingly understated for an AMG, lacking the more obvious and muscular stance of previous AMG offerings.

Inside, there’s a similar theme, with the typical Mercedes-Benz luxury appointments but with a sportier, AMG twist. The steering wheel is chunky and comes with AMG branding, metallic shift paddles and a pair of rotary dials/buttons that allow you to alter the various drive modes and settings.

The one on the right allows you to switch between the pre-set Comfort, Sport, Sport+ and Individual modes, while the one on the left can scroll between the various individual aspects to tailor the settings to the conditions.

In typical modern fashion the design is tech-laden, with a digital display for the instrument panel (that can be switched between various graphics) and a large, tablet-style central multimedia touchscreen that controls the majority of the car’s non-driving functions.

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.

The new C-Class has grown slightly in size compared to the model it replaces, most notably with a 26mm increase in the wheelbase which you can feel in the cabin.

The front seat space is good, with excellent adjustability for the power-adjustable seats and steering column. I had no trouble finding my ideal seating position which makes for a more enjoyable and uncompromised driving experience.

Rear space is a bit tighter (which is typical for this segment/size of vehicle), but thankfully the standard seats do have very deep sculpting in the backs which allow for more knee space and foot room.

However, at approximately 180cm (six-foot), I wouldn’t like to sit behind my seating position for long periods as my knees were touching the seat back, and headroom is compromised with the panoramic glass roof.

In terms of small item storage there’s a lidded console box in between the front seats as well as a pair of cupholders and a small tray where you can place your mobile phone.

It’s worth noting, though, that early examples of the C 43 in Australia do not have a wireless smartphone charging pad, with that reportedly being introduced from February production.

While that’s good news, it’s not really competitive in this day and age to offer a car costing six-figures without such technology.

There’s also only a single USB-C power outlet in the front, which is another disappointment, but there is a pair in the back.

Mercedes does win some points back for a respectable 455-litre boot, which has a nice wide load opening that will make packing luggage easier.

We’ll get to the major change under the bonnet shortly, but another significant alteration for this latest C 43 is the price.

It now starts at $134,900 (plus on-road costs), which pushes it well above its market rivals, the BMW M340i xDrive and Audi S4, which start at $104,900 and $106,200, respectively.

However, Mercedes has added more technology under the bonnet and loaded the C 43 up with standard equipment, including its '4Matic' all-wheel drive system, adaptive damping, rear-wheel steering and 20-inch alloy wheels.

In terms of creature comforts, the C 43 is well-appointed, with leather upholstery, a head-up display, augmented reality navigation, a panoramic sliding sunroof, and a Burmester 3D surround sound system.

There are two option packages for the C 43. The 'Digital Light Package' costs $2400 and adds Multibeam LED headlights with 'Ultra Range' highbeam, 'Adaptive Highbeam Assist Plus' as well as active light function and cornering light function.

The 'Performance Ergonomics Package' includes AMG Performance front seats, an AMG Performance steering wheel in Nappa leather and microfibre and the 'AMG Track Pace' system for an additional $5200.

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 biggest talking point about this new car is the engine, with AMG downsizing from the old C 43’s six-cylinder to a 2.0-litre four-cylinder turbocharged petrol engine.

But it’s not just any turbocharged four-pot, because it is fitted with technology that Mercedes claims has been inspired directly from its Formula One team.

While the F1 team engine facility is based in England, this engine was designed and developed by the Mercedes-AMG team at its Affalterbach headquarters, but the concept of the electric turbocharger reportedly comes from the engine that powered Lewis Hamilton to multiple world championships.

The electric exhaust gas turbocharger - to give it its official name - uses a small electric motor on the turbocharger shaft to spin up the blades without having to wait for any exhaust gases to pass through it first.

To power the electric turbo the C 43 is equipped with a mild-hybrid 48-volt electrical system.

Mercedes claims this means reduced lag and improved throttle response for a sportier driving experience. 

It also helps make this small engine produce big amounts of performance, with AMG extracting 300kW of power and 500Nm of torque from this 2.0-litre, which is more power than the previous six-cylinder C 43 managed.

The engine is paired to a nine-speed multi-clutch transmission, which isn’t a dual-clutch with a pair of clutches operating on every second gear ratio, but instead uses a “wet start-off clutch” for better take-offs and smoother shifting on the move (at least in theory).

Power is sent to the road via all four wheels thanks to Mercedes’ 4Matic all-wheel drive system.

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. 

Despite the smaller engine you can hardly call the C 43 miserly, with a claimed combined urban/highway cycle rating of 9.1-litres per 100km. That’s only a 0.2L/100km improvement over the old six-cylinder.

On test, which included a return trip from Sydney to Bathurst via motorways and some dynamic back road driving, we saw a return of 11.8L/100km on the car's onboard computer.

While hardly hybrid-worrying, it’s impressive to think that driven modestly, such a potent engine can return a single-digit fuel figure.

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.

Let’s start with the good news. The new Mercedes-AMG C 43 is a quick car. The engine may be small in size but the electric turbocharger does its thing and provides plenty of punch.

You can get a performance boost, too, thanks to the belt-driven starter generator, which acts as a mild hybrid and gives you a surge of 10kW for a brief period if you need a sudden burst of extra speed.

The chassis is well-sorted, too, at least from a dynamic point-of-view. The rear-wheel steering can provide up to 2.5 degrees of turning, which improves handling at speed and manoeuvrability when parking.

However, there are some less-impressive elements to the C 43, too. The obvious one is the drama, or rather the lack thereof.

As I said at the beginning, the C 43 has never been as wild or raucous as the V8-powered C 63, but when you buy an AMG there’s a rightful expectation that it will provide some thrills.

The C 43 simply doesn’t have that character about it. Yes, it’s fast, but it produces that speed with efficiency rather than excitement.

And it’s not an engine size problem, because even the 2.0-litre four-cylinder A 35 and CLA 35 offer more ‘wow factor’ than the C 43.

Yes, the engine makes noise under acceleration (and it can be altered between discreet and sporty) but even at its best it sounds muted and lacks the evocative tone of a V8 or six-cylinder engine. 

Another disappointment is the transmission calibration, with the gearbox awkwardly shifting out of first gear on multiple occasions during our test drive.

In the taller gears it felt smooth enough cruising along, but given its low speed shifts we’d like to spend more time in the urban environment before passing final judgement. 

The other notable element of the driving experience we struggled with was the ride quality. While fine on the smoother motorways, our test drive included time on some patchy country back roads and the C 43, even in the ‘Comfort’ suspension setting, was simply too firm.

Riding on low profile tyres, the adaptive dampers struggled to isolate the cabin from the imperfections in the road, leading to a fussy ride at times.

Overall the C 43 is a good car, but it feels like there are still some areas where Mercedes could improve it to make it really live up to the AMG badge.

The C43 gets a comprehensive list of safety equipment that leaves little out. Obviously there are the usual passive safety items, like 10 airbags, including dual-front combined pelvic/thorax airbags and a front centre bag that drops between the front seat passengers to minimise the chances of a head clash.

Also included as standard is autonomous emergency braking front and rear (covering speeds between 7.0-200km/h), adaptive cruise control with active stop/go, a 360-degree parking camera, 'Active Parking Assist', 'Active Lane Keeping Assist', 'Blind Spot Assist' and, of course, anti-lock brakes with 'Brake Assist' and 'Adaptive Brakes' with Hold function and electronic stability control.

Also included are dusk-sensing LED lights, rain-sensing wipers and run-flat tyres with tyre pressure warning.

The C43 also comes equipped with Mercedes’ 'Driving Assistance Package Plus', which adds even more safety gear. This includes 'Active Blind Spot Assist', 'Active Brake Assist with Cross-Traffic Function', 'Active Emergency Stop Assist', 'Active Lane Change Assist', 'Active Lane Keeping Assist', 'Active Steering Assist', and 'Active Stop-and-Go Assist'.

While the C43 hasn’t been specifically crash-tested, the latest C-Class was rated by ANCAP with a five-star score for all models except the upcoming C 63 S E Performance.

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 C 43 is covered by Mercedes’ five-year, unlimited kilometre warranty, which has become the new standard for the luxury car market.

Service intervals for the car are at 12 months/25,000km, which is on par with industry standard.

Mercedes-Benz Australia will offer a service plan for the C 43, prices were yet to be confirmed at the time of publication but the company has indicated it will be similar to the C300. 

That means $550 for year one, $900 for year two, the third service costs $1000 and the fourth year service costs $2450 - for a total of $4900 for the first four years of ownership.
