Range Rover vs MG Im5

What's the difference?

The Range Rover Autobiography long wheelbase is an outstanding SUV that is not just beautiful to drive but makes family practicality a priority, too, 

The price is reasonable relative to the competition, the features list is long and complementary servicing offers peace of mind.

If you don’t need the third row, I’d consider the standard wheelbase Autobiography even if it does reduce legroom, there’s still plenty of space.

My son stopped short of giving the Range Rover Autobiography full marks "because there are no massaging seats in the second row".     

The MG IM5 Performance is fast, comfortable, quiet and super refined. Putting some minor spec and active safety niggles to one side, it offers the features, tech and price to match it with its well-credentialled and already popular mid-size EV sedan competitors. Is there room for one more? We think there should be.

This fifth-generation Range Rover debuted in 2021 and despite its smooth, modern styling this SUV retains the familiar traditional Range Rover look with the short squared bonnet, flat roofline and tall windows.  

Let’s talk about the wheelbase, because it has a huge impact on passenger space.

We had the long wheelbase which is 3197mm between the front and rear wheels - that’s 200mm more than the standard wheelbase. 

Just look at those stretched rear doors in the photos - this is a go-anywhere limousine, or go-anywhere daycare centre in my case.

The overall length of the long wheelbase Range Rover is 5252mm. That’s big, but the design of this SUV doesn’t make it appear enormous.

What I don't like are the retractable door handles. They take a while to pop out and they look and feel cheap. Land Rover has used these on its other SUVs and if I had time I’d pen a letter asking the company to please stop. I’m sincerely hoping this review will do the same thing. I await your response JLR.

I think the tail-lights are pure genius. The pencil thin design is such a brave move away from the norm where brands are going over the top with LED lighting, and the simplicity is refreshing.

Inside, a traditional-looking Range Rover cabin awaits you with the flat dashboard, the low window sills contrasted by super modern touches like the displays and fully digital dials.

It’s sumptuous, luxurious, but not over the top. Again some people are looking for bling and gimmicks, but you won’t find them here - and I like that. This interior feels solid and substantial, but plush. 

Playing spot the straight line on the outside of the MG IM5 is like an automotive design version of Where’s Wally? There aren’t many, in the midst of an unrelentingly curvaceous exterior treatment.

At close to five metres long and two metres wide the IM5 is appreciably longer (+211mm), a little wider (+27mm) and a bit taller (+33mm) than a Tesla Model 3. Think BMW 5 Series in terms of overall size.

And the soft-form shape is functional; the swoopy liftback boasting an ultra-slick 0.24 drag coefficient.

That said, I’m not convinced by the ‘Periscopic’ cameras informing the driver assistance systems from the front guards. They scream tacked-on afterthought. But a touch-only initial opening function for the flush door handles is cool and makes life easier.

The curves continue inside with soft-padded surfaces around the dash and doors, but the straight edge obviously came out for the 10.5-inch central media screen and vast 26.3-inch upper display. There are next to no buttons; even exterior mirror adjustment is directed from the screen to a multi-function steering wheel control.

System software (powered by a Qualcomm ‘Snapdragon’ chip) is lightning fast with a two-finger up and down swipe shortcut function on the central screen for ventilation and other functions.

The interior is light and bright thanks to the enormous panoramic sunroof. It’s been fine in cooler winter conditions during this test but it could be interesting to revisit in the heat of an Aussie summer

There are two interior colour schemes available - the ‘Highland Grey’ of our test car or ‘Dover Beige’ for those brave enough to live life with the threat of scuff marks on your shiny new car’s glamorous but vulnerably light interior.

Range Rovers have been a family favourite for decades and they’ve been doing school runs and trips away long before other brands even thought about producing SUVs for families.

So what you’re buying is Land Rover’s decades of knowing how to make a family SUV and you can tell by little things such as, how wide the doors open, how easy it is to get in and out of (even for little kids), the flat floor, the good visibility (thanks to low window sills), and then there’s the space and cabin storage. Stuff other brands seem to be still working out.

The second row seats in the Autobiography have electric sun shades, dual-zone climate control and the window seats are power adjustable and heated.

My eight-year old couldn’t resist playing with his electric sunshade and the seat adjustment, but fortunately the driver has an override switch which let me turn off his 'seat privileges’ as he called it. 

Being the long wheelbase means the rear doors are long and heavy. So while the eight-year old could open them, he had trouble closing them. 

The long wheelbase offers unrivalled legroom in the back and that meant my wife and I could put our own seats back further for our own comfort -even with a baby seat behind us.

Enormous door pockets, a giant centre console storage area, cupholders in all three rows, USB ports, wireless phone charging and in our case an optional domestic power outlet ($130) made this a comfortable, roomy, well equipped cabin.

Sure, the third row isn’t exactly spacious, but I’ve never met one that is. 

The intelligent seat folding system is remarkable. From the boot or side doors you can electronically adjust the second and third rows - either to raise them or lower them so they are flat for storage.

With all seats in place there is 229 litres of cargo space still left in the boot, but with those back seats folded flat you have 713 litres of capacity - and that’s just up to the cargo cover. 

The Range Rover Autobiography has air suspension and this means the SUV can lower itself to an 'Access' height to make it even easier to get in and out.

There’s plenty of breathing room up front and in terms of storage one of the first things worth calling out are the long but relatively narrow door bins. No good for anything above unusually slender bottles, even if they’re lying down.

No conventional glove box in the dash, but there is a large lidded box (cooled and heated) between the seats that doubles as a centre armrest. It’s supplemented by a big stowage area underneath the flying buttress style centre console.  

There are two cupholders in the centre console as well as a wireless device charging pad in front of them with a vaguely phone-shaped oddments bin alongside it.  

Move to the rear and the IM5’s 75mm wheelbase advantage over the Tesla Model 3 is clear. Heaps of knee and headroom for me at 183cm sitting behind the driver’s seat set to my position. 

But… the seat sits low which pushes your knees up into the air to the point where my thighs are not contacting the seat cushion. Even though the rear seat reclines to a certain degree it’s a problem compounded by a chronic lack of room for your toes under the front seat. Awkward.

There are map pockets in the front seatbacks, modest bins in the doors and a fold-down centre armrest with two cupholders. Adjustable ventilation in the rear of the front centre console always makes life in the rear seat more pleasant.

The car also houses ‘Strong Magnets’ at various points around the cabin and boot, with a configurable adapter able to lock a phone or tablet into place for the entertainment of, in our case, back seaters. 

Speaking of devices for entertainment, there are two USB-C sockets and a 12-volt outlet in the front and another USB-C and 12V in the back, so charging isn’t an issue. 

The IM5 is a liftback so the boot aperture is generous and a capacity of 457 litres with the rear seats up is decent for a car of this size, although that’s less than the Tesla Model 3 (594L) which has an additional well under the floor. 

Still, enough room for the largest (124L) and smallest (36L) suitcases from the CarsGuide three-piece luggage set with some room to spare.

The power tailgate can be operated hands-free via the key or an always welcome under bumper kick function.

Volume expands to 1290 litres with the rear seats folded and there’s a modest 18-litre ‘frunk’ under the bonnet.

The bad news is a repair-inflator kit rather than a physical spare wheel, but the better news is the IM5 Performance can tow a 1500kg braked trailer (750kg unbraked).

The IM range also features the ‘MG iSmart’ app allowing remote control of various functions including charging, checking vehicle location and route planning. 

At $80,990, drive-away, the IM5 Performance sits at the top of a three-grade line-up that starts with a 75kWh RWD Premium model at $60,990, followed by a mid-spec 100kWh RWD Platinum for $69,990, both drive-away.

Its most prominent competitor is arguably the Tesla Model 3 Dual Motor AWD ($80,900), with others including the BYD Seal Performance AWD ($68,798), Hyundai Ioniq 6 AWD Epiq ($86,500) and Polestar 2 Long Range Dual Motor Performance ($80,380).

Worth noting, too, the IM6 range - essentially the same car with a taller SUV body - has the same model walk-up and identical pricing.

Once you’ve crossed the $80K threshold it’s fair to expect a decent basket of standard fruit and aside from the dynamic and safety features we’ll get to shortly, the IM5 Performance comes to the party.

Highlights include a double-glazed panoramic roof, power-adjustable (12-way driver, six-way passenger) heated and ventilated front seats (also heated in the rear), dual-zone climate control, 20-speaker audio (with digital radio), 256 colour ambient lighting, a power tailgate (with hands-free function) and 20-inch alloy rims.

There’s also adaptive cruise control, a heated steering wheel, wireless Android Auto and Apple CarPlay, LED headlights, keyless entry and start, wireless device charging (50W), a 10.5-inch central control screen and a sweeping 26.3-inch upper screen; the right side for instrumentation and car data, the (touch-sensitive) left side for multimedia and other onboard functions.

There’s more and it’s clear this car at least matches or betters its direct competitors for included equipment.

The 4.4-litre twin-turbo petrol V8 is a perfect match for the Range Rover Autobiography.

There’s enormous power at 390kW and a colossal 750Nm of torque, but it’s delivered so smoothly and without sounding like Armageddon is beginning.

You might here the engine referred to as the P530. That signifies it’s petrol and makes about 530 horsepower. 

All that grunt means that despite weighing more than 2.7 tonnes, this SUV can hurl itself from a stand still to 100km/h in 4.8 seconds. 

An eight-speed automatic sends the drive to all four wheels. And making this SUV incredibly capable off-road is an excellent four-wheel drive system with a low range gear, plus a maximum ground clearance (thanks to the adjustable air suspension) of 283mm and a wading depth of up to 900mm.

There is a six-cylinder diesel, but if you decide on that instead of the V8 then it's all over between you and me. That’s how good this V8 is.

The MG IM5 Performance is powered by an electric motor on each axle - the rear (372kW/500Nm) more powerful than the front (200kW/300Nm), for overall outputs of 572kW (that’s close to 770hp) and 802Nm of pulling power.

The official term for that amount of grunt is… a lot. And we’ll get to what it means on the road in the Driving section shortly.

Now, you’re going to use a lot of fuel. But that’s okay because this will probably be your last petrol car and the next one will be electric so let’s go out with a bang - last drinks at the petrol bar! Land Rover says you’ll use 11.8L/100km.

After a week of punishing my Range Rover with school drop offs, shopping centre car parks, hilly suburbs, motorways and rural roads the petrol pump told me we’d used 19.8L/100km.

I’m not shocked by that consumption. This is a 2.7 tonne all-wheel drive twin-turbo V8 SUV that was almost always ferrying around four people with a pram, garden supplies and shopping in bumper to bumper traffic. A real world fuel test. 

There is that six-cylinder diesel and a hybrid version of the Range Rover, but this V8 engine suits the character of the SUV perfectly - anything else and it’s like eating reduced fat ice cream.

The MG IM5 Performance features an 800-volt electrical architecture which means the 100kWh NCM battery can accept a DC peak charge of close to 400kW.

Only snag is the highest you’ll currently find in Australia is 350kW. But even at that rate you’ll still be looking at a 30-80 per cent charge in just over 15 minutes. Maximum AC charge rate is 11kW.

Claimed range is 575km (WLTP) which is less than the Tesla Model 3 Dual Motor AWD at 629km.

Over a week of city, suburban and some freeway running we saw average energy use of 20.6kWh/100km which is on the high side for an EV of this size but maybe not for one with this kind of performance potential. 

Driving the V8-powered, long-wheelbase, 2.7-tonne, Range Rover Autobiography is a lot easier than it sounds. Really, it’s the Range Rover’s height above sea level which will strike you first.

You’ll lord it over other cars. The length doesn’t come into it - even for parking because the visibility is so good, the steering is so light and the engine is civilised and smooth.  

This is truly an easy and enjoyable SUV to drive, with power and performance whenever you need it. 

There are several drive modes from a 'Dynamic' sporty one, which makes the engine more responsive and suspension firmer, to off-road settings.

Most of the time I left the Range Rover in 'Comfort' mode for the softest ride, but with 530 horsepower lurking in the background ready to jump out and eat up hills and overtaking.

The front seats are wide, comfortable and supportive even after hours of driving. 

First things first, the IM5 Performance is supercar fast. This 2.3-tonne five-seater blazes from 0-100km/h 3.2 seconds and with its dual motors combining to produce 572kW/802Nm, eye-widening performance always resides underneath your right foot.

But it’s not all about straight line speed. Ride comfort is excellent. Underpinned by an all-new platform, the IM5’s suspension is by double wishbones at the front and multi-links at the rear. But the key to its bump and rut smoothing ability is air suspension and ‘continuous control’ active damping.

Fold in double-glazing on the full-length glass roof and side windows, as well as active noise cancellation and you have a serene interior environment at any speed. Also worth noting the front seats are great; as grippy as they are comfortable.

Not only that, despite its relative heft, this mid-sizer steers well, too. Not the last word in road feel but it points accurately and the standard rear steering helps with prompt (but never jerky) cornering turn-in. Flick to ‘Sport’ mode and the IM5 is up for some enthusiastic running.

The rear wheels can turn up to 12 degrees in the opposite direction to the fronts at slow speed, which makes for a usefully tight 10-metre turning circle. But above that, at lesser angles, it adds extra stability and decisiveness in the way the car steers through even tight, twisty sections.

Rubber is top-shelf Pirelli P Zeros on 20-inch alloys (245/40 fr - 275/35 rr) and it grips hard, especially in the wet weather over much of the test period. Braking is solid, as it needs to be, with ventilated discs all around and four-piston callipers at the front. 

No adjustable regen braking but you can feel the ‘Cooperative Regenerative Brake System’ (CRBS) doing its thing when you lift off the accelerator. 

The physical rear view is modest thanks to the slope of the back window reducing its functional area for the driver to that of a 1950s VW Beetle. Even the interior rear-view mirror is tiny and folds up into a recess in the headliner if you’d prefer life without it.

But that’s where a rear camera view popping up on the upper screen display (accessed via the right-hand steering wheel click control) comes in handy. Side camera views are also available as is a 360-degree overhead view, which makes parking straightforward.

If you need more parking help there are various self-parking modes including a nifty ‘Curbside’ function that will realign the car hands-free if you’re parallel parked too far out from the kerb.

In a similar vein, a ‘Rainy Night’ mode projects left and right rear views onto the main screen using AI to enhance clarity and highlight pedestrians and cars.

Overall the ADAS (Advanced Driver Assistance Systems) are relatively unobtrusive but we found ourselves switching off the incessant overspeed chime that sounds for 10 seconds if you creep over the indicated speed limit, even when the system has misfired on the correct speed. For example, 40km/h school zones on a Sunday.

The over-zealous driver distraction warning also occasionally issued a visual and audible slap on the wrist when I was looking straight ahead. Tellingly, there’s a specific quick screen for turning both these functions off, but it kinda defeats the purpose of having them in the first place.

We also found the adaptive cruise control to be hesitant in multi-lane environments, reducing speed occasionally because the system seemingly believed a car was set to merge, when it wasn’t.

No independent ANCAP safety assessment at this point but there’s a full suite of active safety tech onboard including AEB, lane departure warning, blind spot detection, rear cross-traffic alert & braking, forward collision warning, lane-change assist, tyre pressure monitoring and heaps more. And we touch on how it all operates in the Driving section above.

There are no less than nine HD cameras, 12 ultrasonic sensors and three millimetre-wave radars on duty.

If a crash is unavoidable there are seven airbags including full-length side curtains and a front centre bag. Multi-collision brake also minimises the chances of subsequent impacts after an initial crash. There are also three top tether points and three ISOFIX child seats anchors across the second row.

All right on the pace for this part of the market and the IM5’s competitive set.

The warranty is good with five-years and unlimited kilometre coverage.

There’s also five years roadside assistance and a complimentary five-year/130,000km service plan.

Yep, that's complimentary, as in free servicing for five years. I didn’t believe it myself and called Land Rover to check and was told that it does indeed mean free-of-charge.

The MG IM5 Performance is covered by a seven-year/unlimited km warranty, which is a plus, but the catch is it’s conditional on authorised dealer servicing. Go elsewhere and the term drops to a more common five years/unlimited km. The drive battery is covered for eight years/160,000km, which is the norm in the Aussie market

Servicing is required every 12 months or 20,000km with charges averaging $586 per workshop visit for the first five years, which is on the high side for an EV, even at this price point, the average bumped up by a more than $1400 doozy at year four.

MG IM models are sold (with service available) through all of MG’s 100-plus dealerships across the country, so no concerns there.
