Chrysler 300 vs Holden Commodore

What's the difference?

The Chrysler 300 SRT is a big, fast, well-equipped and super-comfortable point-to-point tourer that’s also able to soak up the stresses of a city commute with ease. It’s also showing its age in terms of design, obscenely thirsty, dynamically flawed, and offered with a bottom-of-the-class ownership package. A fun place to visit but make sure you’re ready for permanent residency.

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 NSW Highway Patrol has adopted the 300 SRT as its weapon of choice, and psychologically I reckon they’re onto a winner.

A high waistline, small glasshouse and big 20-inch rims combine to give the 300 a chunky, take-no-prisoners stance. And this intimidating beast filling the mirrors is enough to make even the most determined speedster drop their bundle.

Except for the SRT badge at the back, the exterior is a chrome-free zone, with black finish on the big honeycomb grille, window frames, and dark chrome wheels dialing up the overall air of menace.

The rear view is similarly imposing, with a large slab of almost right-angular boot lid topped by a pronounced body-colour spoiler.

At this point, we have to call out less than perfect panel fit. On our test car for example the intersection of the bonnet and front clip above the headlights was messy with inconsistent shut lines and poor alignment.

Inside not much has changed over the current 300’s seven years on sale, and the design lacks the integrated approach of more modern competitors.

An 8.4-inch colour media touchscreen sits in the centre of a squared oval panel between the central air vents and under an analogue clock, that shape bearing no resemblance to the form of the heating and ventilation control panel below it or the instrument binnacle alongside.

A mass of buttons confronts the driver across the centre stack, steering wheel and door, while genuine carbon fibre inserts add a racy if slightly ironic touch in a close to 2.0-tonne car.

Leather and suede sports front seats look (and feel) the business, and the strongly illuminated gauges are divided by a 7.0-inch multifunction display including a clear digital speed read-out. Which is just as well, because the fussy increments on the analogue dial are hard to read.

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 just under 5.1m long, 1.9m wide and close to 1.5m tall the 300 SRT is a sizeable machine, so it’s no surprise there’s plenty of room inside.

Those up front are provided with a pair of cupholders in the centre console (complete with heating or cooling at the press of a button), storage bins and medium-size bottle holders in the doors, a long oddments tray and a small storage cubby (with 12-volt outlet) near the gear shifter, as well as a sunglasses holder in the overhead console and a big glove box.

There’s also a lidded storage box between the seats, complete with sliding tray, two USB ports, an ‘aux-in’ jack and a 12-volt outlet. Even old school nicotine enthusiasts are catered for with an ashtray insert ready to slip into one of the cupholders and a cigarette lighter to drop into the main 12-volt socket.

Rear seat passengers pick up a fold-down centre armrest with two cupholders and a lidded oddments box, decent door bins with bottle holders, as well adjustable vents at the back of the centre console, two USB ports, and switches for the standard heated rear seats.

Sitting behind the driver’s seat set for my 183cm position I had ample legroom but only adequate headroom. There’s enough shoulder room for three adults across the rear, but the broad transmission tunnel throws a spanner in the works when it comes to centre foot room.

The fully-lined boot is nicely trimmed, with a pair of flip-out bag hooks (22kg capacity), load tie-down anchors, and useful lighting included.

Volume is 462 litres, enough to fit our three-piece hard suitcase set (35, 68 and 105 litres) lying flat on the floor, or the CarsGuide pram, with heaps of room to spare. A 60/40 split-folding rear seat adds extra space and flexibility.

In the case of a flat tyre your only option is a repair/inflator kit, and it’s worth noting towing capacity for the SRT is the same 450kg for a braked or unbraked trailer, where the standard V6-powered 300C can tow a 1724kg braked trailer.

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. 

Forget hybrid, forget turbos, the Chrysler 300 SRT is powered by 392 cubic-inches of Detroit iron… although the 6.4-litre ‘Apache’ V8 is actually built in Mexico.

The engine’s block is indeed cast iron although the heads are aluminium, with the ‘Hemi’ name derived from its hemispherical combustion chamber design.

It’s naturally aspirated, direct fuel-injected and produces 350kW (470hp) at 6150rpm and no less than 637Nm of torque at 4250rpm.

Drive goes through an eight-speed automatic transmission to the rear wheels with a limited-slip diff standard.

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.

A model of fuel efficiency this car is not. Claimed economy for the combined (ADR 81/02 - urban, extra-urban) cycle is 13.0L/100km, the 300 SRT emitting 303g/km of CO2 in the process.

Over roughly 300km of city, suburban and freeway running we recorded 18.5L/100km (at the bowser), and the on-board computer threw up some horrifying short-term numbers as we explored the car’s performance potential.

Minimum fuel requirement is 95 RON premium unleaded and you’ll need 70 litres of it to fill the tank… regularly.

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. 

Roll onto a smooth, dry surface, engage the SRT’s standard launch control function and you’ve dialled in the ability to storm from 0-100km/h in a ludicrously rapid 4.5sec.

Unlike smaller capacity turbo engines, the big atmo Hemi takes a while to develop maximum torque (637Nm), hitting peak pulling power at 4250rpm. Keep the throttle pinned and full power (350kW) is achieved on the cusp of the rev limiter at 6150rpm.

All this fire and fury is accompanied by a beautifully brutal V8 roar courtesy of an active exhaust which tweaks the pulsing note it produces according to drive mode and throttle position. It’s hard not to love it, complete with rude pops and crackles on the over-run.

Beware though, this car is relatively loud all the time, so you’ve got to hope the love affair is a long-term one.

Suspension is by a short and long arm (SLA) and upper A-arms at the front, with a five-link set-up at the rear, and Bilstein adaptive dampers all around.

The switch between Comfort and Sport is swift and marked, with the latter best kept for billiard tables and race circuits. Around town ride in the more compliant setting is agreeably smooth.

Push the big 300 along your favourite backroad and you know you’re asking two tonnes of metal, rubber and glass to move against its will.

The eight-speed auto responds well in manual mode (with wheel-mounted paddles), and the grippy sports front seats do decent job of keeping their occupants stable and balanced, but the sheer mass of this car means you’re never going to get a corner-carving hot hatch-like experience.

And despite a chunky, leather-trimmed sports wheel, the hydraulically-assisted ‘SRT Tuned’ steering isn’t exactly the last word in road feel or sharp response.

Having said that, the fat 20-inch (245/45) Goodyear Eagle F1 rubber grips hard with minimal impact on ride quality, and in a more relaxed mode the SRT is a stress-free and comfortable tourer.

Big acceleration is balanced by big brakes, with beefy ventilated rotors (360mm fr / 350mm rr) clamped by Brembo four-piston calipers front and rear.

The system’s outright power is impressive but can be abrupt on initial application at around town speeds, until you get used to greasing the pedal pressure in.

‘SRT Performance Pages’ allows you to scroll through multiple real-time data screens (timers, G-force, engine performance, etc), which is fun, with outputs downloadable to a USB stick or SD card. The 19-speaker harman/kardon audio system absolutely cranks, and the active cruise control works intuitively, without the frustrating conservatism (taking forever to pick up the throttle) of some other systems

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 warranty world has moved significantly in recent months, and the 300 SRT’s three year/100,000km warranty is now well off the pace.

Yes, it includes corrosion cover and 24-hour roadside assistance, but with the likes of Ford, Holden, Honda, Mazda, and Toyota now at five years/unlimited km, Chrysler is way behind.

Kia moved to seven years/unlimited km in 2014, and there are whispers of the Korean brand shifting to 10 years sooner rather than later.

Service is required every 12 months/12,000km, and no capped price servicing program is currently offered.

With the caveat that labour rates will inevitably vary between dealerships, Chrysler Australia estimates five year standard servicing cost at $2590 (including GST).

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.
