Holden Captiva vs MG Im5

What's the difference?

The Captiva is very, very long in the tooth and is heading towards retirement some time in the next twelve months. Before then, it's a lot of car for the money, particularly the seven seat LS. It's not fast, flash or futuristic but it will do the job and with all of the early problems sorted, will probably do it for quite some time.

The Captiva's low scores are mostly to do with the car just being old and feeling it, with dodgier plastics, slightly undercooked ride and handling and a lack of engine and safety tech. It doesn't mean it's a terrible car, because it isn't and Holden papers up the cracks with a low starting price and good after-sales.

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.

Formerly known as the Captiva 7, the seven seat body has remained mostly the same for its 11 years on sale. The only real changes have been around the front end, with Holden several times fiddling with the grille, lights and bumpers. There's nothing flash about the Captiva, but you know exactly what it is coming at you, with the double grille and big Holden badge.

In profile there's a lot of the original BMW X5 if you squint, right down to the copyright lawyer-dodging shape of the rear quarter window. It also has that X5's big gaps between wheelarch and tyres and a good view of the wheelarch itself. If that's your thing.

Little has changed at the back apart from bumpers and the LED effect lights added in the last update in 2014. It's unlikely you're buying the Captiva as auto haute couture, though.

Inside is basic, and you can place the Captiva's genesis in the mid-2000s, there's a certain generic GM feel to it. The switchgear feels old and clacky, the plastics are hard but do fit well enough. An Audi interior it isn't. The update in 2014 to make the 7.0-inch screen fit in the dashboard is fairly obvious and it's a shame the whole dash couldn't have been replaced. The huge steering wheel surrounds a tightly packed instrument cluster with small dials and a very old-looking LCD panel for trip computer duties.

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 Captiva's interior dimensions are impressive. In seven seat versions, the boot space starts at 87 litres, expanding to a handy 465 litres with the 50/50 split fold rear row stowed. Flop the middle row forward and you're up at 930 litres, a good size cargo area that could swallow a flat-pack wardrobe. If you snaffle a five-seat version, you can remove the boot floor panels to reveal another couple of hundred litres of hidey holes.

There are cup holders up front (two), in the middle row (two) and in the boot (one, strangely) for a total of five. In the seven seater, two will go thirsty.

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.

If you like a choice of engine size, you've come to the right place. The Captiva has three engine specs in the range - two petrols and a diesel.

The smaller petrol, a 2.4-litre four-cylinder, produces 123kW at 5600rpm and 230Nm at 4600rpm. Driving the front wheels, this motor is available with choice of gearbox, either a six-speed manual or six-speed automatic. This 2.4 is only available on the LS and Active.

The 24-valve 3.0 SIDI V6 is available on LT and LTZ and produces 190kW at 6900rpm and 288Nm at 5800rpm.

The single diesel is a 2.2-litre iron block with common rail direct-injection and makes 135kW at 3800rpm and a stout 400Nm within a very usable range of 1750-2750rpm. You can have the oil burner in all three trim levels, driving the front wheels in the LS and four-wheel drive in the LT and LTZ.

Both the V6 and diesel are available only with the six-speed automatic transmission. 

Unlike earlier Captiva models, none of these engines feature a timing belt. Those early engines suffered from issues related to the fabric belt while problems with the later timing chain driven engines are less common. Reliability of the V6 is well-proven in the Commodore while later four cylinders also perform well.

Zero to 100km/h performance varies between the engines. The 2.4 will reach 100km/h in around 10.5 seconds while the V6 is rather quicker at 8.6. The diesel falls right in the middle at 9.6 seconds.

We've not yet carried out a towing review, but according to Holden, towing capacity is rated at 750kg for unbraked trailers and 2000kg braked.

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.

If you're after good fuel economy, the Captiva probably isn't the car for you. 

The 2.4-litre petrol is quoted at 9.7L/100km on the combined cycle but, as we recently discovered, is more likely to return closer to 12.5L/100km.

Diesel fuel consumption on the official combined cycle is listed at 8.5L/100km but our most recent test yielded a slightly startling figure of 12.9L/100km. The diesel's performance, particularly in the gears, is better than either petrol but it appears you'll pay for it.

The big banger V6's official fuel consumption figure is listed at 10.7L/100km, but past CarsGuide reviews suggest 14.0L/100km is a more likely real world figure. As far as fuel economy goes, diesel vs petrol usually falls to the diesel, but not in this case.

Fuel tank capacity is identical across the range at 65 litres.

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. 

You sit on the Captiva rather than in it, a feeling encouraged by the flat, shapeless seats. It doesn't matter which Captiva you choose, the front seats are not exactly huggy but they'll certainly take people of all shapes and sizes. 

You twist a funny knob where the key barrel used to be to start the engine. The view out front and out the sides is commanding as there is a fair bit of glass all around, with just the view out the rear window restricted as it's quite small. If you've got passengers, forget it, but the reversing camera will save the day there.

The ride is, for the most part, reasonable, but will deteriorate along with the road surface. The suspension isn't very quiet and the overall firm feeling delivers passable handling, which you'd expect from a big heavy machine like this. It doesn't have anything like the finesse of much younger metal from Hyundai, Kia and Mazda.

The diesel specs suggest strong performance and that's exactly what you get. It's by far the torquiest of the three engines and shifts the Captiva's two tonnes with reasonable verve. It's a noisy, grumbly unit but works well with the six-speed auto.

The engine specs of the two petrols don't really tell the story. While the V6 is quicker in a straight line, its extra weight knocks the shine off the torque increase and the engine itself isn't a shining example of modern engine tech. Actually, neither of them are, missing out on stop-start and other goodies.

This isn't an off-road review, but moderately ambitious mud-plugging is doable in the AWD models, with a ground clearance of 200mm but no low range or off-road mode. We even checked the manual to make doubly sure there wasn't a diff lock button hidden somewhere.

As ever, the idea here is that when you're buying a Captiva you're buying a lot of space and a cheap ownership experience.

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.

As with all new Holdens, the Captiva owner benefits from a three year/100,00km warranty and lifetime capped price servicing. All prices are available on Holden's website.

Service costs for the diesel are significantly higher than the either of petrols, but do include oil changes.

The standard package also includes a year of roadside assist.

For common faults and complaints, check out our Holden Captiva problems page, which covers known automatic transmission problems, engine problems and diesel problems. There aren't any widespread diesel engine problems with the later version.

Resale value is often a consideration and we've looked at the last major update, released in 2014. 

A seven seat Series II LS from 2014 - the second major update for the Captiva after the 2011 update addressed lingering problems - cost $30,490 when new and will trade at around $13000-$15000, below fifty per cent of the purchase price, with private sales a little higher. 

An LTZ diesel from the same period sold for $41,490 and trades in the 45 to 50 per cent of purchase price and a little over 50 per cent in private sales.

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.
