Mercedes-Benz S-Class vs MG U9

What's the difference?

Mercedes-Benz set out to restore the S-Class' place amongst the greatest sedans in the world.

In the heavily-optioned, near-$250K-plus S450 as well as the extended S450L at $300K as tested (the sweet spot of the range for now), we reckon the Germans have succeeded, pushing safety, comfort and technology boundaries, in a package that is true to the heritage of the series.

Tax-fuelled sky-high prices will certainly keep the S-Class niche in Australia, but the car is more than good enough to dominate its tiny corner of the upper-large luxury car sphere.

The best new car in the world? We reckon it's highly likely. Mission accomplished, Mercedes.

I can’t give you a definitive verdict on the U9 based on our limited time behind the wheel. However, what I can say with certainty is MG is serious about making its first ute a success. The price alone demonstrates how motivated the brand is to win buyers over. Undercutting the likes of the Ranger and HiLux with a physically larger ute is a strong opening move from MG.

The clever features, spacious cabin and smart technology will also help to win over buyers, as will the choice of a conventional diesel engine. But none of that guarantees success. As the dominance of the Ford and Toyota demonstrates, ute buyers are loyal and drawn to the most popular options, so MG will need to fight hard for every sale to ensure the U9 isn't lost in the increasingly crowded ute market.

Most Mercedes models have followed the Russian Doll-style cookie-cutter styling theme, and the heavy family look continues with the W223.

Still, the flush door handles do add a touch of Tesla-esque modernity, while the elegant silhouette and clean lines are in keeping with the luxury aspirations. Larger in every dimension compared to the old W222, the S450 is some 71mm-longer in wheelbase (3106mm) than before while the LWB's has stretched out by 51mm (3216mm), benefiting proportions as well as interior packaging.

AMG-branded wheels look sporty but – in the S450 at least – they're perhaps a tad too gangster. A set of flush alloys would give it a more-modern and techier appearance, in our opinion.

Overall, however, the S-Class ‘7' possesses the prerequisite richness of design. It isn't as bold and mould-breaking as models like the W116 were back in their day, but the styling is still a success.

By the way, the latest S-Class is the first Mercedes to employ the MRA2 longitudinal platform, which is rich in lightweight steels (50 per cent aluminium), is correspondingly stronger than before but also 60kg lighter.

With a drag co-efficiency rating as low as 0.22Cd on some overseas grades, the W223 is one of the most aerodynamic production vehicles in history.

While the fancy tailgate step and the Smart Hatch are the most obvious changes between the LDV and MG utes on the surface, arguably the biggest change is what’s underneath. MG has opted to buck the conventional leaf spring, live rear axle set-up and has instead opted for a more SUV-like independent, multi-link rear suspension.

This explains why such a big ute has a sub-one-tonne payload, but it speaks to MG’s aspirations to try and lure ‘urban’ ute buyers. There is no doubt a large group of ute owners who don’t go off-road regularly and instead use their vehicle as a family transporter.

To that end, opting for a more SUV-like suspension set-up should be beneficial to its on-road manners and unladen ride. Unfortunately, as mentioned earlier, we couldn’t test that because our drive was limited to unsealed roads. But it was enough for us to get an initial impression of how the U9 drives and the early signs are positive.

The engine sounds like a traditional ute, with the gruff diesel ‘chug’ and smooth pulling power. The towing test provided was well below the 3500kg maximum rating, only 1500kg, so naturally the U9 has little trouble pulling the horse float along.

As for the ride on the suspension, it's fairly well composed on a gravel road and offers no obvious signs of struggle on more challenging muddy trails and creek crossings. So there are promising signs that the U9 should be able to hold its own against the more established ute contenders.

For the beginning of our day with the S-Class, we were chauffeured from home to a mansion in Kew, a blue-chip Melbourne suburb. Our heavily-optioned S450L featured most of the aforementioned extras – including the Business Class Package and Rear Entertainment Package – and the experience was predictably, sumptuously memorable.

Reclining individual rear seats with easy-reach tablets, armrests offering access to all multimedia and available climatised and massaging cushions and backrests... we're no longer in our normal ride, Toto.

Yet, all these trinkets and gizmos are mere add-ons, that can turn a stretched Caprice into a flash hen's night carriage if enough money and glitz is thrown at it.

No, the new S-Class must impress in an altogether less tangible and more philosophical manner, involving all the senses, and not just what we see, hear and touch. It must appeal beyond the superficial. Otherwise, it is not a large Mercedes-Benz luxury sedan in the classic manner.

This is a Herculean task for the Stuttgart designers and engineers. By and large, though, the Three-Pointed Star has succeeded in achieving something special.

In its perception of peerless quality and engineering, the W223 is striving to move forward and look back simultaneously to the glory days of the seminal W126 (1980-1991). This is through meshing traditional virtues like solidity and quality materials while dazzling its passengers with technology that is still friendly enough to want to enhance your experience.

You can sink into the soft lounge seats, watch the world pass by silently outside and never be aware of the road underneath or the engine ahead. Double glazing, exquisite and aromatic fabrics and materials and lush tactile surfaces work their magic inside the car, while an airtight and aero body, solid platform, air suspension and a muted yet muscular powertrain all do their thing underneath. The atmosphere is special and rarefied. That's what an S-Class needs to be and that's what is happening in our $299,000 (as tested) S450L.

The same more-or-less applies up front, as the same trim, leather, wood and technology surrounds the driver and passenger. The spectre of the car that is surely The Car of the Last Decade – Tesla's Model S – is evident in the portrait touchscreen and sparse, almost wallflower dashboard design and layout. No big imposing architectures here.

Yet, while the American upstart actually takes stuff away, the S-Class packs the cabin with subtle features that – like when the planes stopped flying last year and the birdsong subsequently returned – only become obvious once the cabin's design simplicity clears all the white noise for you to be in a better frame of mind to enjoy them.   

Take the haptic interface, for example, as it is perhaps the best we've experienced; the sense of well-being garnered from the cumulative effects of profound seat comfort (the massaging function was never switched off), cocooning micro climate environmental control, orchestral levels of audio entertainment and the theatre of light and vision performed by the two available screens; it is an automotive experience like no other. And the eye-tracking 3D-effect navigation set within the electronic instrumentation. No need for cinematic glasses to get the effect. The driving position itself, by the way, is also first class.

Room to stretch and grow for sure, and in every direction. But room for improvement? You betcha.

Your tester had a headache after a little while staring at that woozy 3D map. The central vents – four at the front, two in the rear – look and feel cheap, leaving us mentally redesigning them; they are frightfully out of place here; the carryover column-stalk auto lever should have been binned in 2005. And, even though the digital instruments have a number of options, none are elegant enough for the S-Class. That's an especially subjective criticism, clearly, but one that – in the context of classic Mercedes luxury sedan contenders – is justified given how timeless the Bruno Sacco era of Daimler design was. Look him up, kids.

Still, after a couple of hours behind the wheel, with our senses reset to calm, it is obvious that the S-Class cabin is a unique and wonderful place – as it should be at a cool quarter-of-a-million dollars.

Job done.

PS At 550 litres (20L more than before), the boot is massive and luxurious enough to sleep in.

That SUV-like interior and the larger dimensions make for a very pleasant cabin with loads of space. We didn’t get too much time to experience the multimedia system, but the 12.3-inch touchscreen looks good and operates smoothly, while the inclusion of large physical buttons for the air-conditioning and audio system is a positive for those who value ease-of-use.

There’s a generous amount of room up front, but it’s the back that really impresses. Unlike the sometimes cramped back seats in a conventionally-sized dual-cab ute, the U9 has plenty of legroom and headroom for four or even five adults to fit in comfort.

There’s also plenty of small item storage, including a wireless charging pad (but only on the high-grades) and USB outlets just ahead of the gear selector.

As for the tray out the back, that is so important to ute buyers, it measures 1600mm by 1600mm at the top, but narrows to 1230mm between the wheel arches. Despite its big size, the payload is only rated at 870kg for the Explore, 835kg for the Explore X and just 770kg for the Explore Pro.

However, MG has introduced a party trick no-one else, not even LDV offers, in the tray. At the press of a button, the rear tailgate opens and then with another press a section of the tailgate drops down, revealing a step. While not the quickest way to climb into a tray, it might be the nicest and is definitely the easiest this reviewer has experienced locally.

The even more elaborate party trick the U9 offers is what MG calls a ‘Smart Hatch’. This allows for the rear glass to retract and the bottom of the cabin to recline into the interior, creating a direct connection between the tray and the cabin for especially long items. While MG is, rightfully, very proud and keen to promote the Smart Hatch, it must be noted it is only available as an option on the Explore Pro and costs $5500 (which is nearly 10 per cent of the total cost of the car) so you’ll want to really need the extra space.

By not having to worry about developing its own ute from scratch, MG was able to focus on its key selling strength - price. MG has a reputation for its aggressive pricing strategy in Australia, trying to win over buyers with the most affordable or best value products in any given market sector.

To that end, the MG U9 range begins at just $52,990, drive-away, for the U9 Explore, undercutting not only the Terron 9 Origin (from $53,674, drive-away), the Ford Ranger and Toyota HiLux dual-cab pick-up ranges. It's inline with the similarly-sized GWM Cannon Alpha (from $51,990 drive-away). 

For $52,990 the U9 Explore comes with 18-inch alloy wheels, side steps, painted tub liner, synthetic leather seats, keyless entry and ignition and a six-speaker stereo with digital radio and wireless Apple CarPlay/Android Auto.

Next up in the range is the U9 Explore X, which starts at $55,990, drive-away. For the extra money you get 19-inch alloys, a cargo slide rail with a hook in the tray, heated front seats, acoustic glass, vehicle app connectivity, voice command, a wireless smartphone charging pad, satellite navigation, Amazon music and the ability to receive over-the-air updates.

The flagship Explore Pro is priced from $60,990, drive-away, and has 20-inch alloy wheels, an eight-speaker JBL sound system, a panoramic sunroof, suede headlining, heated outboard rear seats and the clever tailgate step we’ll detail later.

Where are the V8s?

Right now, the only W223 you can buy is powered by an all-new 2999cc 3.0-litre in-line direct-injection six-cylinder turbo petrol engine dubbed the M256, complete with double overhead cams, an electric compressor intercooler and assistance from a 48-volt mild hybrid system and integrated starter-generator, adding 16kW and 250Nm to the 270kW of power at 6100rpm and 500Nm of torque from 1600-4500rpm.

The 9G-Tronic torque-converter automatic transmission and 4Matic all-wheel drive system combination is a first for the S-Class in Australia.

Top speed is limited to 250km/h, while the 0-100km/h sprint-time takes just 5.1 seconds in both models. Impressive for a two-tonne-plus luxury limo.

MG has plenty of hybrid knowledge, but has opted to keep it simple for the U9. It’s powered by a 2.5-litre, four-cylinder, turbo-diesel engine, which should be popular with the ute crowd.

It produces a solid, if unspectacular, 160kW and 520Nm, enough for it to offer a 3500kg maximum braked towing capacity, which is also something that should be popular with potential buyers.

The engine is paired with an eight-speed (torque-converter) automatic transmission and 'Super Select' 4WD system capable of sending drive to all four wheels.

Like so many new brands in the ute market, MG was keen to highlight that the transmission is built by ZF and the 4WD system is from BorgWarner, both brands with a long history in their respective areas.

With the aid of the mild-hybrid system, the S450 returned a combined average of an impressive 8.2 litres per 100km, which translates to 187 grams of carbon dioxide emissions per kilometre. 95 RON premium unleaded (or higher) is recommended. In the urban run it consumes 11.3L/100km (11.5 for S450L), and just 6.4L/100km (6.5 for S450L) in the extra-urban result.

At 76 litres, the fuel tank will allow a combined average range of about 927km between refills.

As all three variants are powered by the same engine and all return the same fuel economy. Rated at 7.9L/100km on the combined (urban/extra-urban) cycle.

As our test drive was limited to off-road only we can’t assess its real-world usage, so that will need to wait until we can spend extended time behind the wheel.

Notably, with an 80-litre fuel tank the U9 has a theoretical driving range of more than 1000km, which is great for anyone looking to take their ute on a long road trip.

In terms of safety, the U9 has all the usual features you should expect of any new car in 2025. This includes airbag protection for all occupants, plus active safety features including autonomous emergency braking, adaptive cruise control, lane keeping assist and a host of others.

That’s enough for it to achieve a maximum five-star Euro NCAP score and MG expects the same from ANCAP. However, it must be noted Euro NCAP crash tested the LDV e-Terron 9, the electric version of the ute, which obviously has no diesel engine in the front of the vehicle and instead a smaller electric motor and a storage space.

It also worth noting even on our limited, off-road only drive, the driver attention system seemed very sensitive, which suggests better calibration is needed. So we’ll reserve final judgement on the other systems until we can fully experience them, too.

Unlike many luxury brands that persist with a sub-par three-year warranty, Mercedes-Benz offers a five-year/unlimited kilometre warranty.

Intervals are every year or 25,000km, with a capped price service plan starting at $800 for the first year, $1200 for the second year and $1400 for the third year, totalling $3400. Alternatively, there is a Service Plan starting at $2700 for the first three years (saving $700 from the normal capped-price service plan), $3600 for four years and $5400 for five years.

This is a crucial area for many ute buyers, so MG has tried to make itself as appealing as possible to discerning pick-up prospects.

However, the U9 is covered by MG’s seven year warranty, not the newer 10 year coverage from its passenger vehicles. And even then, that requires you to service the vehicle via an authorised MG dealer for the full seven years to apply.

However, this only applies to non-commercial use vehicles, so while tradies will be covered, fleet buyers are stuck with a five-year warranty.

Over the first five years, if you spend the $2395 capped price costs, you’ll get the extra two years of coverage. The first service is due after 10,000km, but the rest are at 12-months/15,000km.

MG has also worked on expanding its dealer and servicing network to respond to some growing pains and ensure owners aren’t burnt and are more likely to return for their next MG. There are currently 120 MG dealers across Australia with plans to gradually expand that footprint into regional areas following the launch of the U9.
