Land Rover Discovery vs MG Im6

What's the difference?

The Land Rover Discovery D300 S is a great family-friendly 4WD wagon.

It’s quiet, refined, and supremely well appointed; it’s also very nice to drive on-road and it’s a lot of fun – and very capable – off-road. 

It’s packed full of driver-assist tech and its Pivi Pro system is a real treat to use once you’ve mastered the art, which doesn’t take long.

But you could say all of those same things about the new Defender. 

So, is the Discovery still relevant? I reckon it is … at least for the time being.

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.

As always, I’ll avoid waxing lyrical about the styling of a vehicle – suffice to say, it looks good.

In terms of dimensions, this Discovery is 4956mm long (with a 2923mm wheelbase), 2220mm wide and 1888mm high.

It has a listed kerb weight of 2437kg.

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.

The interior has a real premium feel about it, but it still serves as a very practical space.

In terms of cargo space, there is 2391 litres with the second and third row stowed away; 1137 litres with the third row stowed away; and 258 litres with all rows in use.

The third-row seats can be either manually folded down into the floor to use that area as cargo space, or lifted up into a seating position.

There is a load-space cover, light, luggage tie-downs, bag hook and 12v in the rear, and two USB charging sockets for the third-row passengers.

The second row is a 60:40 electric-folding set-up with manual slide and powered recline, centre headrest and armrest, as well as map pockets, and door-moulded recesses. Second-row passengers get two USB C and one USB A charging points, air vents, air-con controls and more.

The front seats are 14-way electrically-adjustable with captain’s armrest, grained leather seat facings with Ebony interior; the Pivi Pro 11.4-inch touchscreen with digital radio, Apple CarPlay and Android Auto; as well as one USB A and three USB C points.

The Discovery has a fixed front and rear panoramic roof.

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.

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 Discovery has a 3.0-litre inline six-cylinder twin-turbo-diesel engine – producing 220kW at 4000rpm and a whopping 650Nm at 1500-2500rpm – working with a mild hybrid system. 

Those impressive power and torque figures don’t tell the whole story of just how well the Disco’s engine is able to punch this big unit along the road at a comfortable clip and – bonus – its chunk of torque, useable across a decent rev range, comes in very handy when off-roading.

It has an eight-speed automatic transmission and an all-wheel drive system.

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.

Fuel consumption is listed as 7.5L/100km on a combined cycle. 

Fuel consumption on this test was 9.8L/100km. That’s sound considering I did a lot of high- and low-range 4WDing on this test and the Disco is quite a hefty unit.

The Land Rover Discovery D300 S has an 89-litre fuel tank, so, going by those fuel-consumption figures, I’d expect an effective touring range of about 860km, but remember that figure includes a built-in 50km safe-distance buffer. 

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.

The Discovery is very impressive on-road. No surprise really as it has always had a reputation as a comfortable on-road cruiser – and it's lost nothing in this latest iteration. 

It is a smooth driving experience: quiet, refined and you suffer little to no noise from outside intruding into the cabin. 

The seats are very comfortable and supportive, and that makes it perfect for long-distance trips. 

The straight-six engine and eight speed auto are a nice combination, quietly effective, and well-managed. 

Acceleration is good with sharp throttle response, so you can crack on the pace when you need to, say, for instance, from a standing start or when you need to overtake a vehicle. 

In terms of overall driving experience, there’s nothing too outrageously exciting or dynamic on offer here, because this is a large SUV, but it’s always comfortable and it’s lively enough if you want to give it the boot. There are paddle shifters if you want to get fancy with your up- and down-shifting.

It’s not all good news: visibility from the driver’s seat is a bit pinched out the rear of the Discovery (due to its styling); there is pronounced body-roll through corners; the brakes are quite spongy, with a real delayed-action feel about them; ride is a tad harsh because you are rolling along on 20-inch tyres and rims, which is something I’m not so used to; and, the steering column is manually adjustable only, which I reckon is a bit slack for such a pricey vehicle.

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.

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 Discovery has a five year/unlimited km warranty with five years roadside assistance.

The service plan applies over five years/130,000km (whichever occurs first) with a cost of $2650.

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.
