MG ZST vs Holden Calais

What's the difference?

Will the MG ZST Essence fit a small family? Absolutely, and all but the middle seat passenger will be comfortable but there are areas open for improvement. Like it's safety, laggy tech and adding a few extra items in the back seat.

Yet, it still offers a good host of features and an attractive package for a reasonable price tag. Unfortunately, my son missed having the basic amenities but did like the sun roof.

A best-of-both-worlds option that should have us questioning our SUV obsession, the Calais Tourer delivers plenty of practicality perks and a higher ride height in a dynamic and car-like package. The equipment levels are spot on, including the comprehensive safety package, and it you act smartly, you'll get a hugely long warranty to boot.  

It sure is thirsty, though, and we can't help but think plenty of owners would be happier with a smaller, more-efficient engine. 

Being the newer and shinier version of the ZS, the ZST presents as a nice little package with its full suite of LED exterior lights, shiny chrome accents and its well-shaped body.

The front is distinctively different from its design muse with a darkened grille, and redesigned fog lights that feature new air intake vents. Other highlights include the 17-inch two-tone alloy wheels with sporty red brake calipers lurking behind them.

The interior is pleasant with a massive sunroof creating a light-filled space and giving the illusion that the cabin is larger than it is.

The synthetic leather upholstery and trims seem robust and perfect for families, but also feel quite plasticky under hand. The red badge embossing on the headrests is lovely, though.

The dashboard is well-proportioned and headlined by an upgraded 10.1-inch touchscreen multimedia system and fully digital instrument cluster.

The gearshift feels a tad too skinny and tall for the general aesthetic but the circular air-vents add some cute personality.

Less an SUV (happily), and more a high-riding wagon, the Calais Tourer borrows a little from the Subaru XV in its exterior design, sporting the same plastic cladding over each wheel arch. Clearly there is a whole heap of shared DNA between the Sportwagon and Tourer, and so it offers similar perks; like its SUV-shaming boot space. 

Elsewhere, the Tourer shares the same soft and rounded edges as the rest of the Commodore range, and while it is genuinely quite handsome from most angles, it is at its best viewed front on, where a simple front-end is bookmarked at each corner by a narrow headlight on top, and an encased fog light below. It’s all a touch understated, sure, but it looks sharp in the metal.

Inside, it’s a clean and functional cabin design, with most of the touchscreen functions controlled by a simple row of four horizontal buttons, and with a gloss-black surround encasing the centre console. The thin leather wheel feels lovely under the touch, and the contrasting door trims and soft-touch materials find their way into the backseat, too. 

Practicality is hurt by a lack of individual storage options and a back seat that has only two USB-A ports for its amenities.

The cabin space is spacious, though, and both rows have a decent amount of leg- and headroom despite the massive sunroof.

The steering wheel features height but not reach adjustment and to accommodate I have to sit much closer to the wheel than normal thanks to my poor little T-Rex arms.

Individual storage is the best up front with a small middle console and glove box, two cupholders and two drink bottle holders. The doors also feature large storage bins, which is great to keep the cockpit feeling neat.

The rear row gets two map pockets and a small storage bin in each door. There is also a (very) shallow storage nook at the back of the middle console… think a packet of gum or small wallet size.

My seven-year old isn't as comfortable in the rear because it lacks directional air vents, reading lights and a fold-down armrest. All items which will hinder an adult's comfort, too.

The boot space is a good size at 359L but you can bump it to 1187L with the rear seats folded, the backrest featuring a 60/40 split.

The height of the floor is adjustable and when set in the lowest position creates a deep well to tuck larger items, like luggage, into.

The hard cargo cover can be awkward to shift around or store but is otherwise out of the way when it counts.

Other amenities accentuate the premium-feeling the Essence is going for with the heated front seats and electric drivers seat offering well-padded comfort but on longer journeys, I miss having adjustable lumbar support.

The rear seats aren't as comfortable as the front only because the synthetic leather feels slippery, which is accentuated when you hit corners!

In terms of technology, you get two USB-A ports in each row but the front also gets a 12-volt port. You miss out on fast and wireless charging options.

The multimedia system looks great but can be sluggish to respond and the apps can be slow to load but I like the built-in satellite navigation.

The upgraded sound system has six speakers instead of four but the sound quality is a bit tinny with music and calls.

It was simple to connect to the wired Apple CarPlay. It also has Android Auto, Bluetooth connectivity and AM/FM radio.

The Tourer serves up identical storage space to its Sportwagon near-enough twin, with 793 litres of storage (to the roof line) with the rear seats in place, and 1665 litres with the rear seat folded down. That’s about 200 litres more than the regular Commodore hatchback.

Where the Tourer does differ from the Sportwagon is in its exterior dimensions, measuring 5004mm in length (versus 4986mm in the Sportwagon) and 1525mm in height (versus 1483mm). Width and wheelbase are identical, though (1871mm and 2829mm), and so the interior space dimensions - like headroom and legroom - are identical no matter which of the estate-style Commodores you opt for. 

The key dimension here, though, is ride height, with the Tourer offering 20mm more ground clearance (42mm greater height overall) than the Sportwagon. That, combined with the on-demand all-wheel-drive system, allows for some light off-roading - though you won’t be conquering Everest.

Up front, expect two cupholders hidden under a gloss-black cover, as well as power and USB connections located in a central cubby. The back seat is home to two extra cupholders hidden in a pulldown divider, and there is room in each of the doors for bottles. The back seat is also home to air vents (but no temperature controls) and two USB charge points located just below the vents.

The Calais has long formed the most luxurious rung of the Commodore ladder, and the wagon-ish Tourer is without doubt the most practical version. It will set you back $45,990 ($47,990 drive-away) in the guise we’ve tested here, and $53,990 In Calais V specification.

Not to be sneezed at, then. But it does arrive with plenty of stuff to help justify your investment.

Outside, you’ll find 18-inch alloys, a handsfree auto-opening boot, heated mirrors, keyless entry with push-button start, a remote start function, rain-sensing wipers and automatic headlights with LED DRLs. Inside, expect leather seats that are heated in the front, a leather-wrapped wheel, dual-zone climate control, standard satellite navigation and a wireless charging pad for compatible phones.

On the technology front, an 8.0-inch touchscreen pairs with an eight-speaker stereo, and it’s both Apple CarPlay and Android Auto equipped. There’s also a genuinely impressive standard safety package, too, but we’ll drill down on that under the Safety sub-heading.

The Essence variant has a 1.3-litre, three-cylinder turbo-petrol engine with a maximum power output of 115kW and 230Nm of torque.

It's a front-wheel drive and features a six-speed auto transmission. Overall, it has enough power to keep up with traffic on the open road but you have to be firm with the accelerator to keep your speed consistent.

A really rather good 3.6-litre V6 engine Is parked under the bonnet, feeding 235kW at 6800rpm and 381Nm at 5200rpm to all four wheels as required, thanks to an on-demand all-wheel-drive system. The suspension is tuned specifically for its high-riding antics, too.

The grunt is fed through a nine-speed automatic, and while Holden doesn’t quote a specific zero-to-100km/h time, it’s no slouch from the lights. 

The 3.6-litre engine means a braked towing capacity of 2100kg, and an unbraked max of 750kg.

The official combined cycle fuel figure is 7.3L/100km and my real-world average came in at 7.7L. That is after a good mix of urban and open-road driving, so the usage is good.

Based on the combined fuel cycle and the relatively small 45L fuel tank, expect a driving range of around 616km.

Not so good, I’m afraid. The offical number is on the high-side at 9.1 litres per 100 kilometres on the claimed/combined cycle (though that's less than the equivalent Subaru Outback), but we were averaging a smidge under 14.0L/100km after what was admittedly quite a lot of city driving. Still, that’s high.

Emissions are pegged at 212g/km or C02, and the Tourer’s 61-litre tank will accept cheaper 91RON fuel, or an E10 blend.

The ZST Essence has an okay amount of power relative to the car's small size.

It's an adequate cruiser when I ferry just my husband and son around, but feels a full load of luggage and people.

The steering is responsive and it's an easy car to manoeuvre in tight car parks or city streets, which is great. The visibility is pretty good despite the chunkier pillars and you feel confident when checking your blind-spots.

While the suspension is fairly forgiving and ride comfort is decent, you will still notice the bumps, especially when seated in the back.

The cabin suffers from some wind and road noise and at higher speeds we had to find we raise our voices a bit to be heard. Around town, you don't notice it.

This is just a personal preference but the brake and accelerator pedals are skinnier and more centrally positioned than I prefer. You get used to it, though.

The ZST is pretty easy to park and it's great that you have a 360-degree camera system but the image quality can be grainy. You get rear parking sensors, too, but miss out on ones at the front.

Really very good. That 3.6-litre engine (why they haven’t offered the Tourer with the smaller and smarter turbo engine is something of a mystery) might be a touch old-school and a touch thirsty, but it’s a rich and powerful thing, and it gives the Calais-stamped Tourer a perky personality that defies its dimensions.

The Calais Tourer was built in Germany, and fitted with an engine and transmission from the USA, before undergoing local tuning here in Australia (think bespoke steering and suspension tunes calibrated both at the company’s testing facility and after a 200,000km test on Aussie roads), and it’s the last of those Dr Frankenstein ingredients that have had the biggest impact here. 

The Tourer’s ride is fantastic, perfectly poised between firm composure and everyday comfort, and - like most good wagons - it will honestly leave you wondering why so many people are clamouring aboard the SUV train when you can all the space with better dynamics in a humble estate. 

The nine-speed ‘box is smooth and sharp in its operation, too. But the fuel use is a concern. Sure, we spent the bulk of our time in the city, where stop-start traffic naturally uses more fuel. But then, surely so would most owners? 

You’ve got to hand it to the Lion for the standard safety package here, which includes the Holden Eye camera system as standard, adding auto emergency braking (AEB), lane keep assist, lane departure warning and forward collision warning. You’ll also find semi-autonomous parking, a reversing camera and rear parking sensors.

The Calais Tourer adds blind-sport monitoring and rear cross-traffic alert to that pretty comprehensive package. All of which helps the Commodore range qualify for the maximum five-star ANCAP safety rating.

Finally, you can add six airbags and two ISOFIX attachment points to the mix.

The ZST Essence comes with a seven-year/unlimited km warranty, which is on par with coverage offered by a growing number of its rivals.

There is a seven-year or up to 70,000km servicing program for a total cost of $2339 or an average of $334 per service, which is very competitive for the class.

Servicing intervals are at every 12 months or 10,000km, whichever occurs first, but could be annoying if you travel a lot.

Holden has recently relinquished the initial warranty offering, now including the Commodore in its seven-year, unlimited-kilometre warranty program, meaning it mixes with the very best in the aftercare business. For now, at least; normally, the Commodore carries the brand's standard three year/100,000km warranty. But be on the lookout for the return of this deal if you miss out this time.

Service intervals are pegged at 12 months or 12,000kms, and the Commodore falls under Holden’s extensive capped-price servicing program, and it will cost between $259 and $359 for each of the first seven annual services.
