MG Im5 vs Mercedes-Benz V-Class

What's the difference?

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.

The Mercedes-Benz V-Class, and in particular the Mercedes-Benz V220d, lives up to the notion of a luxury people-mover – for the most part. The leaking door is a concern, but may be confined to this vehicle only.

But in most every other way it has the whole prestige bus thing sorted. There is no denying that a more affordable van from a less, shall we say, desirable brand would do just as good a job.

But if you need to be seen to be offering the most luxurious people-mover you can buy in Australia, then you really ought to be looking at the V-Class…. just maybe go for the V250d, if the budget can stretch that far.

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.

This doesn’t look like your everyday Mercedes-Benz commercial van – the V-Class is certainly more at home parked in the driveway of a luxury hotel than alongside the back door in the alley behind it. 

Admittedly it isn’t as attractive as the Avantgarde flagship, but it has the whole Benz ‘family look’ thing going on, with a stylish grille, swept headlights and a streamlined body. A box on wheels it may be, but it’s a box with nicely rounded edges.

The 17-inch, five-spoke alloy wheels are plain, and the halogen headlights and daytime running lights don’t have quite the same wow factor as the LED units in the high-end model, but it wears that Benz badge loud and proud. And the extremely dark tinted rear windows ensure the privacy of your occupants, as well as giving off the vibe of high-end plush.

I know it’s hard to stray from the formula for a van, but I particularly like the back end of the V-Class – it is reminiscent of the original Vito, with low, broad-set tail-lights and a near-flat backside with a huge tailgate, which doubles as an awning to stand under if the weather is a bit Melbourne. 

The interior is typical Benz, or, in the case of the V220d, Benz on a slight budget.

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. 

With the optional eight-seat setup, it’d be hard to think of this van as impractical. And if you consider that it also has a boot capacity of 1030L in its most downsized form (and 4630L with the rear seats removed), any argument seems null and void.

The fact the boot is electrically operated, and that it has a separate tailgate glass opening section, and that you can open the boot using the keyfob – not to mention the kerbside door – just adds to the pragmatic appeal of this van.

The six rear seat backs can all be flattened down, and you can tumble them forward, too – the kerbside seats in a one-by-one motion, the driver’s side ones tumble two-at-a-time. It takes a bit of muscle to do those ones.

Essentially you can set it up as a parcel van if you want, or even as a mobile office – the rear seats can be configured to face each other, in ‘conference’ style. But you need to know that this isn’t an easy process, and once you’ve got it set how you want it, you’ll probably end up just leaving it as is.

Loose-item storage isn’t great, but at least the door pockets are large enough for some bottles and documents.

No matter which way you like it, those in the back will have good ventilation (it has a three-zone climate control system with a separate fan controller in the back above the second-row seats), and a decent amount of space. Crucially, there are no cup or bottle-holders, nor any loose item storage in the back two rows – there are mesh nets on the backrests of the very front seats, but that’s it.

If you plan to use this as a mover of smaller people, the V-Class’s child-seat anchor-point game will not disappoint. It has four ISOFIX anchors (two in each row) and six top tether points – yep, every spot in the back!

Up front there’s a problem with the cup-holder situation, too – there are two, but they’re way down on the floor, meaning it’s hard to access your cuppa on the move. In fact, loose-item storage isn’t great, but at least the door pockets are large enough for some bottles and documents. There’s a sunglass holder, too. The little media screen is a bit disappointing in its size, and the Comand controller codpiece that juts out from the centre console can take some getting used to.

Connecting and reconnecting a phone isn’t too difficult (although you have to pair audio streaming separately to phone streaming – which is weird), and there’s no extended smartphone capability such as Apple CarPlay or Android Auto. Using the navigation system is very simple, but the graphics are extremely aftermarket looking – that’s no bad thing, because Benz’s maps always looked a bit 1990s, but these ones are somewhat cartoonish.

There are two V-Class models you can buy;  this newly added V220d variant, at $74,990, or the high-spec V250d Avantgarde, which is listed at $87,200.

That’s a pretty huge difference, especially considering you get plenty of equipment in the lower-spec version. To get a better understanding, let’s list off what’s standard, and what you get if you fork out the extra $12,210 for the top model.

The V220d has a 7.0-inch media screen with Garmin maps, dual USB ports, Bluetooth phone and audio streaming, auto headlights and wipers, DAB+ digital radio, CD, auxiliary and SD input, electric parking brake, electric front-seat adjustment with memory settings, cruise control, colour driver information screen with digital speedometer, black leather trim and sports pedals.

There’s three-zone climate control and velour floor mats up front, too, while parking moves are made easy with the brand’s Active Parking Assist system, which can semi-autonomously park the van for you. Other niceties include front and rear parking sensors, a reversing camera, dark tinted rear glass, heated/folding/auto-dimming side mirrors, and electric side doors and tailgate (with opening glass section).

Stepping up to the V250d sees the addition of a 15-speaker Burmester sound system, ambient lighting (three colours), a higher-resolution 8.0-inch media screen with integrated Wi-Fi hotspot and online access and navigation with live traffic updates, a 360-degree surround-view camera, adaptive cruise control, illuminated door sills in stainless steel, a rear parcel shelf, 18-inch alloy wheels, anodised roof rails, a body kit, chrome exterior trimming, LED adaptive headlights with automated high-beam and LED daytime running lights, and tyre-pressure monitoring.

There’s some separation between the two in terms of engines as well – see below for more detail on that.

And for a little bit of context, there are no other luxury-branded people-movers out there. Buyers may consider alternatives like the Volkswagen Multivan Executive at $83,390 (wait, how much?), but in all honesty, if you can forego the badge and just want space for your money, the Kia Carnival Platinum ($61,290) offers a considerably better value equation.

The car we tested had the optional roof rails ($649) and parking system with surround-view camera ($616) fitted, and was an eight-seat model rather than a seven-seater, which adds $1346 to the price.

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.

Both the V220d and V250d are powered by 2.1-litre turbo diesel engines, but in differing states of tune.

The V220d has 120kW of power and 380Nm of torque, while the V250d pumps out 140kW and 440Nm. Those figures are decent given the capacity of the engine, and to help keep fuel use down it has stop-start, sadly it’s a bit grumbly and overactive.

Both run seven-speed automatic transmissions and are rear-wheel drive. The Benz vans have strong towing capability, with an unbraked towing capacity of 750kg, while it can deal with braked trailers up to 2500kg.

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. 

Mercedes-Benz claims that over a mix of urban and highway driving, the V-Class will return 6.3 litres per 100km, no matter whether you choose the V220d or the V250d – which is pretty good given the thing is long (5140mm), wide (1928mm) and relatively heavy (almost two tonnes).

Over a lengthy drive in the V220d – some of it on a twisty mountain road, some in stop-start traffic, most on the freeway – I managed 7.2L/100km. This will rise with added bodies, but not by much.

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.

My drive saw me chauffeur my partner and our dog down to Cooma, where we then took my parents down the coast. We put the V-Class’s flexible seating to the test, as we had to buy a massive bathtub and bring it back with us. This proved that, although this thing is a luxury van, it can also be a hugely practical delivery van.

The comfort on offer was perhaps the biggest advantage for my passengers – with superb suspension composure, ride comfort and body control, the V-Class is like a big boxy limousine.

It won’t set your heart racing in corners as there’s quite a lot of body roll to contend with, but the steering is direct and very nicely weighted, making for easy progress whether you’re piloting it down a mountain pass or dealing with roundabouts or parking lots. The turning circle is small, which in turn makes the van feel smaller than it actually is.

The brakes can feel a little numb underfoot, meaning you might find yourself pushing a little harder on the pedal than you think you ought to. The response is good, though, even with weight on board.

The extra, effortless grunt of the V250d would be advantageous.

What was a little surprising was a lack of torque at higher speeds for overtaking moves. On a slightly sloping country back road with four adults on board, I expected there to be well and truly enough for a quick overtaking move – but the drivetrain didn’t quite have the grunt to get the job done. At least, not in the Comfort drive mode.

By using the ‘Dynamic’ drive selector and choosing Sport mode, there was extra push on offer – the gearing changed, and so did the throttle response – and that made overtaking moves a little easier. But still, the extra, effortless grunt of the V250d would be advantageous, and I know I wouldn’t like having to play with the drive-mode switch every time I overtook. Just leave it in Sport mode? You’ll pay the price on fuel use. 

Around town the seven-speed auto went about its job really well, offering smooth shifts in all situations. The transmission can clunk when you engage park or shift to reverse, though, which isn’t overly premium, and there is some turbo lag that you’ll have to remember when you prepare to take off from traffic lights. Another thing that didn’t necessarily persuade my passengers of the premiumness on offer was the fact that the kerbside door leaked when it was raining. Not good.

The V-Class has been awarded the highest possible ANCAP crash test score of five stars – it achieved that in 2014, based on a EuroNCAP score that was put through local screening.

It has plenty of safety kit to keep your mind at ease – whether you’re a driver or passenger.

There are six airbags, including full-length curtain coverage, and the V-Class has a reversing camera with dynamic guide lines, an adaptive electronic stability control system (ESP) with load sensitivity and cross-wind assist, rollover mitigation, trailer-sway control (when fitted with a genuine Benz towbar), hill-hold assist, flashing brake lights under emergency braking and driver-drowsiness detection.

There are other handy features, including auto headlights and rain-sensing wipers, auto-dimming interior and exterior mirrors, forward collision warning (not AEB), blind-spot monitoring, lane-keeping assist (but not with steering intervention).

You’ve got spend up to the V250d to get the adaptive cruise control system, but there’s still no AEB on that variant.

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.

Mercedes-Benz Vans backs the V-Class with a three-year/200,000km warranty plan, which is good.

The company has also introduced a new capped-price servicing plan for the V-Class, with maintenance due every 12 months or 25,000km, whichever occurs first. The fact the distance intervals are so far apart could be a bonus for business operators, but the costs are high: the first service costs $556, then the following two visits will set you back $1112 each time. Yikes.

A longer capped-price plan with lower prices would make this van a lot more attractive to business owners. A Kia Carnival could make a lot of sense in that regard, too – even business operators get a seven-year/150,000km warranty with a seven-year/105,000km capped-price plan, and the same cover for roadside assist.
