What's the difference?
The combined sales of GMSV’s 1500 and 2500 HD Silverado offerings currently represent more than 36 per cent of the Over $100K pick-up segment, in which extensive local remanufacturing of US-sourced vehicles to RHD ensures six-figure price tags.
Clearly, these large Chevrolets, which are primarily designed for carrying and towing heavy things, have established a strong foothold in Australia.
We recently trialled the latest MY24 version of the biggest Silverado from a tradie’s perspective, to see if this giant could be a superior alternative to local one-tonne ute offerings in the dual roles of weekday worker and weekend leisure machine.
Meet the IM6 Performance, “presented by MG”. And that last bit’s important, because while it’s marketed and sold by the Chinese mainstream player, it really is unlike any other MG going around.
Think of it as like a Lexus to Toyota, or an Audi to Volkswagen, with the Chinese brand going premium, and seemingly making a direct play for Tesla’s fan base. How so? Well, there’s only two models in IM line-up (sound familiar?) with the IM6 a rival for the Model Y, and the IM5 (which we’ve also tested) a competitor to the Model 3.
The IM6 is spacious, pretty sumptuous and ridiculously fast. And it offers up some features I’ve only ever really seen in high-end German metal. But it’s also got some quirks.
So, can MG run with the big dogs of the premium car world with the IM6 Performance? And should Tesla be worried? Let’s find out.
This is a serious truck with load-carrying and towing capabilities far beyond Australia’s ubiquitous Ranger/HiLux-sized one-tonne utes. However, those vehicles thrive in urban use due to their relatively compact dimensions so, in that context, this pick-up is simply too large to be a practical alternative. However, if you have more specialised work and recreational requirements, like GCMs as high as 12 tonnes with spacious comfort for a crew of five, this big American would be tough to top.
A super solid first outing from the IM brand. Don't let the pricing fool you, there is still bang for buck on offer in the IM6 Performance, even if it at times feels a bit too digital for my tastes.
MY24 brings a freshened front-end appearance with new fascia, headlights, body-coloured bumpers and grille garnish, black body highlights and more.
With a traditional ladder-frame truck chassis and sprawling 4036mm wheelbase, this behemoth measures almost 6.4 metres in length (6387mm) and more than 2.2 metres in width (2263mm).
It also stands more than 2.0 metres tall (2039mm) and has a vast 16.1-metre turning circle. So, multi-storey car parks, drive-thru takeaways etc are best avoided. And domestic driveways (if wide and long enough to accommodate it) may suffer under its weight over time.
It rides on 20-inch high-gloss black alloys with LT275/65 R20 Goodyear Wrangler all-terrain tyres and carries a full-size spare.
New Z71 off-road suspension includes skid plates and Rancho twin-tube dampers, offering 251mm of ground clearance and 28.5 degrees approach/19 degrees ramp breakover/23.6 degrees departure angles.
However, its 4x4 capabilities would be better suited to accessing rugged worksites, pulling a large caravan out of a boggy campground or towing a large boat trailer up a slimy boat ramp, than hardcore bush-bashing on narrow tracks.
The Silverado’s extensive remanufacturing to RHD, performed on a dedicated production line in Melbourne, exudes OEM standards of fit and finish. The dashboard module is particularly impressive, in providing a mirror image of the LHD original in appearance and function.
The leather-appointed cabin is a highlight, offering palatial space and comfort for all. It features a tasteful blend of contrasting materials and surface treatments, including silver-grey woodgrain inserts on the doors, dash and centre console plus exposed stitching along seams and subtle splashes of chrome.
The entry pathway to the rear seat is expansive, thanks to wide-opening doors and a flat floor with no transmission hump to straddle. There’s executive-lounge rear head and legroom, even for tall people, combined with enough shoulder room to ensure a crew of five can travel in comfort.
I feel almost mean saying this, because there will be plenty of people who like the way the IM6 looks, and I don’t want to rain on their parade. But… I’m not one of them.
It reminds me a bit of the pre-facelift Tesla Model Y, in that it’s largely feature-less and a bit blobby, and there’s not a sharp angle anywhere to be found on the thing. Premium to me means powerful and assured — picture just about any Audi — whereas I just find this a bit bland and soft.
Anyway, I do like the big alloys, the insulated glass roof and the light treatment front and rear.
And I like the cabin. The seats aren’t leather, but they’re super thick and comfortable, and there is a genuinely premium air in the cabin, helped by the acreage of screens and the quality elements, like the little door panels.
The doors unlatch electrically, matching the pop-out door handles outside, but they can be a bit fidgety. Someone from MG told me how they worked (you kind of cover the handle and let the door come to you) but I watched everyone else who tried to open them struggle. If you're at the point where you have to explain how a door handle works, you might have over-egged the pudding.
The second screen below the main one acts a bit like a mobile phone. You can alter your home screen widgets and access the main menu, even as Apple CarPlay is synched at the top. You’ll get used to it, I’m sure, but I found it to be a bit fidgety.
Actually it reminds me a little bit of the Lexus trackpad, or whatever that hateful system was called, where you controlled the main screen via a little mousepad thing, though happily it’s nowhere near as annoying as that was.
With its towering 3762kg kerb weight, the 2500 HD offers a choice of ADR load ratings (NB1 or NB2) which must be specified by the customer at the time of ordering (at no extra cost) to ensure the correct certification for vehicle registration.
The NB1 category allows up to 4500kg GVM/733kg payload, which can be driven by car licence holders. NB2 allows up to 5148kg GVM/1386kg of payload, but requires a truck licence. Our test vehicle is certified for the lower NB1 rating.
The 2500 HD is rated to tow up to 3500kg of braked trailer with a 50mm ball and up to 4500kg with a 70mm ball. These trailer weights are well within its capabilities, given that its GCM rating (how much it can legally carry and tow at the same time) is an eye-popping 12474kg.
Yep, that’s more than 12 tonnes, which allows for trailers weighing more than 4500kg using heavy-duty connections like pintle hooks, goosenecks/fifth-wheel turntables installed and certified by specialist aftermarket suppliers.
The enormous load tub offers almost 2.0 cubic metres of cargo volume and has large external steps front and rear for easier access. The load floor is 2089mm long, 1814mm wide and 533mm deep, with 1317mm between the rear wheel-housings allowing Aussie or Euro pallets to be carried.
It’s protected by a tough spray-on liner, plus there are 12 load-anchorage points, LED lighting, power tailgate and a camera to keep an eye on loads when driving. Our test vehicle was also fitted with adjustable and removable load-dividers, which are part of the GMSV accessories range.
Cabin storage for driver and front passenger includes two bottle/cupholders and a large bin in each door plus a single glove box. The centre console has a large open tray up front, two bottle/cupholders in the centre and an Esky-sized box at the back with padded lid that doubles as a plush elbow rest.
Rear seat passengers get a bottle/cupholder and bin in each door plus two more bottle/cupholders in the rear of the centre console and another two in the fold-down centre armrest. There are also large storage pockets on both front seat backrests and compartments cleverly hidden behind hinged upper backrest cushions.
The 60/40 split rear seat base can swing up and be stored vertically if more internal load space is required. This also provides access to the under-seat storage accessory fitted to our test vehicle. You’d seriously struggle to run out of cabin storage!
The IM6 measures 4904mm long, 1988mm wide and 1669mm tall, and it rides on a 2950mm wheelbase, with IM describing it as a "mid-large SUV", though I expect it will be classed as a medium SUV Australia.
That said, ICE and EV mid-size electric SUVs are not cut from the same cloth, with the latter making use of a flat floor to maximise space. And so it is with the IM6, where backseat room is pretty damn impressive. I’m 175cm, and I had no problem at all with legroom or headroom, plus the same plush seats from up there are in the back, too.
There are also air vents but no temperature controls, and while there are USB ports, there is no regular household-style plug in the cabin.
The glass in the windows is laminated, while the roof is double glazed, which MG tells me is Australian summer-proof, but I guess we'll know for sure in a couple of months.
There’s no shortage of cargo room either. There’s a 32-litre frunk up front, and there’s 646 litres in the boot with the rear seats in place. They’re 60/40 split, and if you drop them, luggage space grows to 1621 litres.
The towing capacity is a braked 1500kg, too, but I don’t expect to see many of these towing a camper trailer around.
Our test vehicle is available only with GM’s 6.6-litre 'Duramax' turbo-diesel V8, 10-speed automatic transmission and dual-range 4x4 system for a list price of $163,000.
Our example has optional 'Slate Grey' prestige paint ($1250) plus GMSV accessories including a powered roller tonneau cover ($3970) and rear under-seat storage ($455) which adds more than $5600 to the price. So, with on-road costs, it's drive-away is more than $170K.
MY24 upgrades include styling, performance, towing and safety enhancements. There’s also a redesigned interior, with its most notable feature being upsized dash screens comprising a 12.3-inch configurable driver’s info display (paired with a colour head-up display) and larger 13.4-inch multimedia touchscreen.
There’s also a premium Bose sound system, Apple/Android connectivity and wireless phone-charging, plus USB ports front and rear, dual-zone climate control, heated leather-rimmed steering wheel (with four-way adjustment), a power sunroof and power sliding rear window.
Leather-appointed seating offers 10-way driver and front passenger power adjustment, heated/ventilated front seats, heated rear seats, rear privacy glass, a power tailgate, tubular side-steps, 360-degree camera (and up to 14 different camera views), full LED lighting including fog lamps and DRLs plus heaps more. It’s what you might call fully-loaded - even without a load.
Premium play means more premium prices, and my IM6 Performance will set you back $80,990 on the road. That might have just sent your eyebrows skyward, but keep in mind it’s faster than some Ferraris, and is swimming with high-end tech, so the bang-for-buck factor is actually still pretty good.
There are cheaper ones, too. The single-motor Premium grade is $60,990 drive-away, albeit with less power and slower charging. Then there’s the Platinum, with a bigger battery and faster charging, which is $69,990
The Performance, though, gets everything IM has to give, including an 800-volt architecture, which means super-fast charging, as well as twin motors, brutal acceleration, a decent driving range and adaptive air suspension.
Elsewhere, you get LED lighting, a big and insulated glass roof, and 20-inch alloy wheels. Inside, there are thick and soft synthetic leather seats that are heated and cooled in both rows, a banging 20-speaker sound system, and wireless charging to pair with wireless Apple CarPlay and Android Auto.
There’s also 'active noise cancellation', and a seat-aware digital assistant which is about the best, and fastest, I’ve ever used. The IM6’s speaker system can locate where a voice is coming from, so any passenger can use the assistant. For example, if you’re in the backseat and say 'hey IM, lower my window', only your window opens. It’s a technology that I specifically remember the German brands crowing about not so long ago.
There’s also a 10.5-inch central touchscreen that controls much of the vast 26.3-inch screen that runs from in front of the driver to the centre of the cabin, as well as clever little magnets embedded in the dash in front of the driver, as well as in the back of the front seat headrests, that are designed to hold phones, iPads or other little accessories.
Also cool is the IM6’s self-parking tech, but there’s also a relatively useless crab walk function, which leans on the rear-wheel steering system to drive diagonally at slow speeds. I’m still not entirely sure when you’d use that one, to be honest.
Honestly, it’s a lot of stuff, and a lot of tech.
The 6.6-litre Duramax turbo-diesel V8, with driver-switchable exhaust brake, is tailored for heavy-hauling with an external engine oil cooler and functional bonnet scoop feeding fresh air to the engine’s intake system.
In the latest MY24 specification, it produces 350kW at 2800rpm and 1322Nm of torque at 1600rpm. That’s 18kW and 98Nm more than the previous model.
The refined 10-speed torque converter automatic with column-shifter is also fitted with an external oil cooler, while closer gear ratios and revised final-drive ratios for MY24 enhance all-round performance.
A dual-range transfer case offers a choice of four drive modes comprising 2WD, 4WD high-range, 4WD low-range and Auto (traction-sensing full-time 4WD). Also new is an automatic-locking rear differential.
Its armoury of advanced towing hardware and technology includes a 4500kg tow-bar with 12-pin wiring harness and integrated trailer brake controller.
Plus, there’s a rear-view camera with hitch guidance, automated trailer lighting test, in-vehicle trailering app with trailer profiles, trailer theft alert, trailer tyre pressure/temperature monitoring and lots more.
New MY24 features include adaptive cruise control which can be used when towing (detecting the additional weight behind the vehicle to automatically increase braking distances). Others are 'Trailer Side Blind Zone Alert' (TSBZA), which extends the blind zone area when towing, plus 'Gross Combination Mass Alert' (GCMA) which alerts if you exceed the GCM.
This is the real party trick of the IM6, because there’s a nuclear power plant under the metal somewhere. All up, the twin-motor setup produces a total 578kW and 802Nm, though I suspect you’re never accessing all the grunt all at once. Still, 100km/h zips by in 3.4 seconds, and the top speed is 239km/h. For the record, that’s exactly as fast the Ferrari Roma Spider I recently handed back, so yeah, it’s properly supercar quick.
The dash readout was claiming 17.5L/100km at the end of our 351km test, which comprised mostly city and suburban driving plus some highway running with a full payload.
Our own figure, calculated from fuel bowser and tripmeter readings, came in slightly lower at 16.8, which is decent economy for a vehicle weighing more than 3.7 tonnes unladen in ‘real world’ driving.
So, based on our figures, you could expect a realistic driving range of around 800km from its big 136-litre tank.
Also on board is a 100kWh Nickel-Cobalt-Magnesium battery that produces a WLTP driving range of 505kms. Pretty good.
Charging is strong, too. The high-tech platform allows for 396kW DC fast charging, which is faster than what is currently offered in Australia. The claim is 30-80 per cent charged in 15 minutes. There’s also an external vehicle-to-load (V2L) port.
Side-steps and large handles on the A- (and B-) pillars assist climbing aboard. It’s a very comfortable driving position, given the multiple seat and steering wheel adjustments along with plush elbow rests on both sides.
The large door mirrors, combined with numerous camera angles including the central rear view mirror's pin-sharp image, provide commanding all-around vision.
The steering is nicely weighted and surprisingly communicative for such a giant, providing good feel and response at all speeds.
The suspension tuning is supple enough to provide a smooth ride, yet retains enough firmness to minimise the ponderous feel inherent in vehicles of this size and weight.
Braking response is also reassuringly strong, without requiring huge pressure on the brake pedal to achieve it.
The 6.6-litre turbo-diesel V8 and 10-speed auto provide effortless performance. With maximum torque tapped at just 1600rpm, the engine is barely ticking over at city and suburban speeds.
And it requires less than 1500rpm to quietly maintain 110km/h on the highway, which combined with its low tyre and wind noise results in a supremely relaxed long-haul cruiser.
With its NB1 GVM rating, we loaded more than half a tonne into the load tub, which combined with our crew of two was just under its 733kg payload limit.
It simply didn’t notice the added weight, storming up our 13 per cent gradient, 2.0km-long set climb with acceleration unmatched by any loaded vehicle we’ve tested on this ascent.
Its engine-braking on the way down using the exhaust brake also set a new benchmark, never exceeding 50km/h and 2000rpm on overrun without once touching the brake pedal.
First things first, don't get too distracted by the word "performance" here. The IM6 doesn't act like a performance car, it feels bit too plush, and bit too digital, for that.
But that's not necessarily a bad thing. Performance cars are often loud, raucous and uncomfortable, and the IM6 is none of those things. Instead, those mountains of power and torque make silky, silent progress absolutely effortless, which feels pretty premium to me.
MG makes a big deal of how much work went into insulating the cabin from noise – with active noise cancellation joined by double-paned insulated glass – and it is a properly calming and quiet space.
Also strong is the suspension, with the adaptive air setup soaking up most bumps and bruises, but I found it can clang over really solid bumps, sounding like it's bouncing off a stopper. The steering is solid, too, with a nice weight, if not overly talkative in the feedback department, while the rear-wheel steering helps eat into the turning circle for tight three-point turns.
The downside, though, is that it all feels a little too digital, and like there's been a little too much overthinking gone into it. Having to push a button to see behind you in a hurry is bonkers (see my explanation in the Safety section below), and the secondary screen is more annoying than intuitive. And there were several bings or bongs I couldn't even identify. All of which interrupts the otherwise calming nature of the drive experience.
ANCAP star ratings are not applicable in this vehicle class, but it does come well equipped with six airbags including side-curtain protection for all outboard seating positions.
There’s also forward collision alert with low-speed AEB, lane departure warning, blind-spot monitoring (including when towing trailers), rear cross-traffic alert, front and rear parking assist, up to 14 camera views including 360 degrees ‘birds-eye’ and more.
There are three top tether points across the second row seat for securing baby capsules/child seats with ISOFIX anchors on the two outer positions.
There is a long list of safety aids on the IM6, and I won't detail the lot here. But I will call out a couple of curious mentions.
As always, the driver distraction warning is annoying, but can be switched off. And MG also counts the IM platform, or what it calls a digital chassis, as part of the safety offering. It has its own digital brain that adapts the air suspension, the rear-wheel steering and the active safety kit on the fly.
The other curiosity is the weird way you see out the back. Rather than fit a digital rear-view mirror to counteract the almost non-existent rear vision, you instead push up on a little toggle on the steering wheel to bring up a live view of what's happening behind you on the central screen.
The Silverado is covered by a three year/100,000km warranty with three years roadside assist.
Scheduled servicing is every 12 months/12,000km, whichever occurs first, and there's no capped-price servicing. This ownership package falls short compared to rivals like Ford's RHD F-150.
The IM6 is covered by a five-year, unlimited-kilometre warranty, rather than MG’S 10-year term. Capped-price servicing is offered for the first five years, with your total bill just under $3000. The service intervals are 20,000kms or 12 months.
