Mercedes-Benz Eqe300 vs MG Im5

What's the difference?

The Mercedes-AMG EQE53 SUV has some serious tech inside and will fit the family in style. If you're after the AMG experience, you may be a little disappointed as this model leans heavily towards plush rather than sports-SUV. And it does plush extremely well but it begs the question whether the AMG factor is worth the extra cash.

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.

We affectionately nicknamed our test EQE53 model the Blue Tic Tac because of its… well, similarity to the mint.

While not uncommon in the EV market, the EQEs pillowy design doesn't exactly scream 'big personality'. However, it does feature some cool features like the massive 22-inch alloy wheels, red brake calipers and the AMG badging at the rear. But that's all that separates it from its non-AMG siblings.

Head inside and it features all of the plush comforts and styling you’d expect from a Merc with some of the best ambient lighting in the business and a sunroof that manages to make the cabin feel airy despite all the black trims. 

Some of those trims, like the synthetic grey panels scattered liberally throughout the cabin, are found in all EQE models and don't reflect the grade level. A trim with better tactility and style would be a point of difference.

The dashboard features three screens in a ginormous panel, which surprisingly doesn’t catch the light but does show fingerprints and every spec of dust on it. Which might annoy you as it's 100 per cent the drawcard for the interior and when it's dirty, it's very obvious.

Although I'm not in love with some design choices, it's still a lovely cabin to spend time in.

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.

The cabin of the EQE53 offers plenty of head- and legroom for its occupants. Using the armrests is also a civilised affair as there's not fighting for elbow positions!

Access to both rows is (annoyingly) more complicated than it needs to be because of the sidesteps - which are, quite frankly, useless on a car like the EQE. They hit your shins/calves when you're not using them and using them feels silly.

All seats offer a tremendous amount of comfort but the fronts benefit from heat and ventilation functions that keep you relaxed year-round. They extend everywhere you need them to to get into the best seating position.

Storage is excellent throughout the car and in the front there's an extra-deep middle console (it swallows most of my arm), a large centre console that features retractable cupholders and a big shelf underneath for bulky items, like a handbag, or as my mum joked, Saturday night’s takeout and a bottle of wine!

Each door pocket gets a dedicated bottle holder and the rear also gets two retractable cupholders and a pair of map pockets.

The boot has 520L of capacity available which is a good size for the class and the wide boot aperture and level loading space make it easy to slide things in and out. You miss out on underfloor storage in the EQE53 model but the back seat has a 40/20/40 split to open up storage options.

The technology looks daunting but is very user-friendly once you spend some time with it. The main multimedia system is responsive and you can access the menus from the steering wheel controls as well as the touchscreen.

The system has wireless Apple CarPlay and Android Auto and satellite navigation, all of which are easy to use. Charging is good with eight USB-C ports (six up front!) and a wireless charging pad.

Despite having four co-pilots this week, the additional screen in front of the passenger remained mostly unused and ended up being more of a novelty.

The real bugbear has been the air-conditioning system. Despite having a pre-climate function, it takes ages for the car to cool down and my eight-year old struggled in the rear the most. The rear vents just don't seem to pump much out, even on the top speed setting.

Once the system has cooled the cabin, though, it's like a fridge. But until it does... you really notice the 30+ degree days!

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 EQE53 is an AWD and has dual electric motors - one at the front and one at the rear.

Without the optioned AMG Dynamic Plus Package, the motors produce up to 460kW and 950Nm but with the package those outputs jump up to a staggering 505kW and 1000Nm!

That means the 3.7-second 0-100km/h sprint time also improves to 3.5-seconds. Suffice it to say, it's enough to blow your hair back and considering we have no roads in Australia you can really let this thing loose on, it's more than enough power for anyone.

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.

Non-AMG EQE models see decent driving ranges over the 500km mark, but the EQE53 has an official range of up to 485km which again positions it in the middle of its rivals. So, not bad, but a larger range would be welcome as the EQE53 is a comfortable road-tripper!

The EQE53 has a a claimed consumption figure range of 23.0 to 25.6kWh and a lithium-ion battery with a large 90.56kWh capacity.

After a week of open-roading, city-driving and not being shy in using its power, my average has been around 25.5kWh, which is solid for an electric performance SUV.

The EQE53 has a Type 2 CCS charging port which means you can hook it up to the faster DC chargers and it accepts up to 170kW on this type of system meaning it goes from 10-80 per cent in as little as 32 minutes. On an 11kW AC system, expect it to hit 100 per cent after 14.5 hours. 

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. 

I really wanted the AMG EQE to be crazy-fun like its petrol-powered cousins but while it has the specs to support that wish, it never feels wild.

That's not necessarily a bad thing, just unexpected for an AMG model. The 53 is still one cool customer and its composure on the road is wonderful but it's a model that a grandparent could get into and not feel overwhelmed by. Power is smoothly delivered and when you need to take off, it responds eagerly .

Steering is firm and responsive but it’s the rear axle steering that makes the EQE53 feel nimble in the city or a tight car park despite its bulky size. It corners well, without much roll and you can tackle a winding road at speed with confidence.

The ride comfort is very good with minimal outside noises finding their way inside and the suspension is plush without feeling like you’re floating on top of the road.

The visibility is mostly good but the wide A-pillar is annoyingly in the way for my driving position and I have to duck my head around it to see clearly on roundabouts.

The 360-camera system is top notch but the camera angle turns when you move the steering wheel, which takes some time to get used to. Otherwise, the EQE53 is an easy one to park.

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 EQE SUV is offered with a five-year/unlimited km warranty, which is not unusual for its grade level but it has a longer-than-usual battery warranty of up to 10-years or 250,000km.

You can pre-purchase a three-, four- or five-year servicing program. The three-year program costs a flat $2240, while the four-year program costs $3525 and the five-year option costs $4085.

All pricing is pretty competitive for the class but servicing intervals are odd at every 12-months or 25,000km as it's typical to see intervals on EVs at 24 months.

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.
