BMW M5 vs Kia Sportage

What's the difference?

Let’s get one thing out of the way: the new M5 is a very good car. Considering the emissions limitations and size increase of its base model, it is an impressive bit of engineering. 

What’s trickier is deciding whether the new car is really better to drive. Less edgy but supremely comfortable and quiet; BMW leaned into the daily usability of the plug-in hybrid M5 rather than amping the petrol-electric system for maximum thrills. And do you know what? That’s fine with me. 

The new M5 still performs on road and track and does an incredible job of hiding its weight (most of the time). Perhaps the G90 is a little more Audi RS6 than F90 in its demeanour but some would argue that’s no bad thing. 

The concept of the BMW M5 is not static, it evolves with the times, and the G90 is no exception. Expect future Competition and CS variants to unlock some extra lunacy.

The Sportage still feels like a super solid offering in its segment, plus the addition of more hybrid options is only going to help.

It does feel a little under-specced in the lower grades, though, considering the everything-and-the-kitchen-sink approach taken by its Chinese rivals.

I feel like I should almost whisper this bit, given it's a dirty word at the moment, but that diesel engine, it's a real peach, and if I wasn't afraid of being run out of Sydney's inner west with pitchforks, that's probably the one I'd be choosing.

The M5’s raw size is what you notice first. The G90 M5 is a whopping 113mm longer, 67mm wider and 37mm taller than the car it replaces, with the wheelbase stretched 24mm.

It is also the most pumped M5 yet, compared to a 520i it is 70mm chubbier at its flared wheel arches. The ‘M5’ insignia on the C-pillar means you’ll know this is the fast one. 

Presence is not in question, then, but beauty? Not the right word. The G90 makes its predecessors — especially the original ‘E28’ — look demure. 

The cabin layout builds on the concept debuted by the iX electric SUV, with twin integrated screens and focus on technology and minimal buttons. Materials are mostly high quality and feel fitting for the M5’s asking price.

All new Sportage models feature a redesigned front and rear end, but they actually have a slightly different look. There's one look for the cheaper models and then one for the top-spec cars, the SX+ and GT-Line.

The changes aren't overwhelming, though. There are fog lights in the more expensive models, but also just more use of black edging, as opposed to the silver edging that frames the bottom of the grille and rear end in the cheaper cars.

Either way, I still really like the way the Sportage has come together. The front end looks bold and powerful, mostly because of the vertically stacked headlights and and the DRLs that really frame the front end, but they've also done a good job of making a fairly big and spacious SUV feel small and not too imposing.

Now, inside the top-spec cars it’s very modern Kia, with a big twin-screen setup, and the dual-function bar beneath them that handles things like climate control, but also mapping and media and those kinds of functions. The cheaper models also get the same look, but swap the second 12.3-inch screen for a smaller driver display.

It means you don't have to dig through the screen for everything, which is always a nice touch. And I also like some of the materials used in the GT-Line, too, like the synthetic wood grain that’s actually nice to touch.

But there are a couple of key downsides. Not quite so much in the top-spec cars, but in the cheaper versions. I hate those constant reminders that you didn't spring for a more expensive model, and there are plenty of those in the lower-spec cars.

In the more expensive models, there are buttons alongside the gearshift, but in the cheaper cars, those buttons are still there, just blacked out and inactive. And even the cutout for the head-up display still exists in the cheaper cars, but of course, there's no head-up display.

All of that combined with some hard and scratchy plastics front and back makes you really want to dig deep for a more expensive Sportage.

BMW has persevered with its twin-screen, minimal-button approach for its 'Operating System 8.5' in the M5. 

The 14.9-inch central touchscreen is bright, responsive and high resolution but the software remains a little strange. The main interface is classy but when looking for settings to adjust you’re presented with a Windows 95-esque panel of small square touch targets. It’s not intuitive. 

Wirelessly mirroring Apple CarPlay or Android Auto works a treat, at least. Digital climate controls keep temp adjustment persistently on screen and a shortcut to fan speed. The nipple-like vent direction adjustment grows on you, as do the digital vent sliders. 

The 12.3-inch digital driver’s display still doesn’t have the freedom of customisation and clarity of Audi’s interface. 

The M5 has two cupholders, a deep central storage cubby, door bins that swallow two 600mL plastic bottles and twin wireless charging pad that resolutely grips smartphones even under the sort of tummy-churning G-Forces this M5 can manage. 

Setting the M5 apart from the regular sedan is a unique centre console bunching 'M Drive' modes, 'M Hybrid' modes and other shortcut functions together next to the gear toggle and M-engraved crystal 'iDrive' controller.

Comfortable front seats are power adjustable with in/out, up/down lumbar support and have two memory positions. 

The 5096mm long M5’s back seat is very spacious. Headroom is good for those beyond 182cm (six-foot), the bench is extremely supportive, while leg and toe room are adequate.

A fold-down centre armrest has two cupholders and there are USB-C charge ports in the back of each bucket seat for a total of four. 

You can buy an accessory mount that holds tablets or smartphones for rear seat passenger entertainment, too.

When you look in the boot, BMW offering a Touring version of the latest M5 makes even more sense. The load aperture is big but the usable space is narrow; the sides intrude on load space. 

The 466-litre space will make fitting suitcases for an airport run tricky and, even with the 40/60 split-fold rear bench, you will struggle to fit a bike in the back. There’s no spare tyre, either.

The Sportage measures 4685mm long, 1865mm wide and between 1665mm and 1680mm tall, depending on the trim.

Slip into the backseat of the Sportage and you’ll find legroom is ample, at least for my 175cm frame, and headroom is ok, without being great - though our test car had the sunroof fitted which could be eating into the space.

Elsewhere in the back though, even the top spec GT-Line just doesn't feel that plush. And by that, I mean some of the materials are a bit hard and scratchy, you don’t get your own temperature controls for the air vents, and it generally just lacks a premium air.

Now, to the all-important point in this segment, and that is boot space. The official VDA numbers are 543-1829 litres for the petrol and diesel cars, and 586-1872L for the hybrid, but the real-world reality is a boot that is deep and wide and really has enough space to carry plenty of groceries.

But there is an important caveat. Under the flat floor there is a temporary spare wheel in the hybrids, where in some of the ICE cars, you get a full-size spare wheel.

There are a lot of different numbers involved in the Sportage story. In fact, there are no less than 13 trim and powertrain combinations, and so 13 different prices you can pay. Easier, I think, if I just pop the graphic up on screen and you can jump to the one you want.

While there are four engines and five powertrain configurations to choose from, not all of them are available across all four trim levels. The SX+, for example, offers no electrified options, while the SX will give you hybrids, but no turbo-petrol choice.

The range opens with the S, which gets 17-inch alloys, LED DRLs, power-folding mirrors and roof rails, while inside there are cloth seats, power windows, a smart key with push-button start, and single-zone air-con with rear-seat vents. Tech at this level is handled by a 12.3-inch infotainment screen with wireless Apple CarPlay and Android Auto, but no wireless charging, which pairs with a six-speaker stereo. The driver then gets a 4.2-inch screen to deliver driving info.

The SX then adds 18-inch alloy wheels, dual-zone climate, standard navigation and rain-sensing wipers.

The SX+ is feeling like a sweet spot, adding 19-inch alloys, LED fog lights, artificial leather seats that are heated up front, wireless device charging, a heated steering wheel and a better Harman Kardon Premium stereo.

Finally, the flagship GT-Line gets the lot, with 19-inch black alloys, or 18-inch wheels in the hybrid, welcome lights, projection headlights, a twin-screen cabin which adds a second 12.3-inch screen for the driver, a powered driver’s seat and a head-up display.

All models also get Kia Connect, which gives you remote access to the vehicle for things like pre-setting the climate, as well as Over the Air updates.

I’ve got to say, though, the flagship Sportage offers largely what the cheapest version of most Chinese SUVs offer, showing just how much price pressure the newcomers are putting on the old guard.

Unlike the Mercedes-AMG C63, BMW has kept the M5’s eight-cylinder heart and this has proven to be a good decision. 

The 4.4-litre twin-turbo petrol engine has been optimised with “a cross-bank exhaust manifold and optimised oil separation”, says BMW.

The V8 spins to 7200rpm though it isn't a screamer, outputting a full-bodied 430kW (5600-6500rpm) and 750Nm (1800-5400rpm).

Augmented with a transmission-mounted 145kW electric motor that can produce up to 450Nm, thanks to pre-gearing, maximum combined outputs are 535kW and 1000Nm. 

Weight blunts punch, though, so despite nearly 100kW and 250Nm more, the new M5 is a tenth slower to 100km/h than its predecessor (claimed), at 3.5 seconds for the sprint.

You can thank a 220kW/tonne power-to-weight ratio, worse than the old car's 233kW/tonne figure. The new G90 claws some time back with brute force, hitting 200km/h in just 10.9 seconds and goes on to a limited top speed of 305km/h.

You can choose from five powertrain settings, starting with 'Electric' and 'Hybrid' for everyday use, while 'eControl' lets you store battery power for urban use.

'Dynamic' provides the best balance, says BMW, while 'Dynamic Plus' is like a qualifying mode. Think maximum combined punch for up to 10 minutes, at which point you’ll have drained the battery. 

Driving in pure electric mode, the take-off can be a little jerky but the quietude and decent power make it pleasant. Power sources are combined expertly in Hybrid and giving it some stick in Dynamic is more than enough to make your passengers feel queasy.

The big news about this mid-life update for the Sportage is the expansion of Kia’s hybrid powertrain, which is now available with AWD, and the inclusion of an eight-speed automatic for the 1.6-litre turbo-petrol variants.

Elsewhere, the 2.0-litre petrol option produces 115kW and 192Nm, pairs with a six-speed automatic, and drives the front wheels. The other pure petrol option is a 1.6-litre turbocharged petrol unit that produces 132kW and 265Nm, paired with an eight-speed auto and powering all four wheels.

Then comes the diesel, which is a 2.0-litre unit making 137kW and 416Nm. It pairs with an eight-speed automatic and powers all four wheels.

Finally, there’s a hybrid option, now with two- or all-wheel drive. It pairs a 1.6-litre turbo-petrol engine and a six-speed automatic with an electric motor and a 1.49kWh lithium-ion battery to produce a total 173kW and 367Nm.

Electric-only range is rated up to 69km in WLTP testing, but the 18.6kWh battery is more likely to give you around 60km in real-world driving. It can be topped up in about two hours using an 11kW AC charger, or overnight on a three-pin socket. 

BMW includes both Mode 3 (public) and Mode 2 (home) charging cables with the M5. 

The M5 uses 3.2L/100km of 98 RON premium unleaded in ADR testing, corresponding to just 72g/km of CO2, so it should sail through the first rounds of Australian emissions regulations. 

Indulging in what the V8 has to offer sees that consumption spike, though. An enthusiastic road drive saw the M5 gulp 12.4L/100km, according to the trip computer.

All pure ICE Sportage grades are fitted with 54-litre fuel tanks, while the hybrids get 52-litre tanks. But the hybrids more than make up for it when it comes to fuel efficiency, with the FWD sipping a claimed 4.9 litres per hundred kilometres on the combined cycle, while the AWD drinks 5.3 litres.

The diesel is the next most-efficient, using a claimed 6.3L/100km combined, while the turbo-petrol needs 7.5 litres, and the 2.0-litre petrol requires 8.1 litres.

Our calculations suggest that, taking the fuel claims at face value, a 2.0-litre petrol Sportage should carry you 666kms on a full tank, while a turbo-petrol will take you 720kms. The diesel should deliver 857kms, while the FWD hybrid (1061kms) and AWD hybrid (981kms) will take you the furthest.

The three M5 elements start with daily usability. We trundled out of Bathurst in electric mode, with the adaptive dampers (and other myriad settings) in Comfort. 

The M5 has steel springs, double wishbone front suspension and a five-link rear axle, all of which has been heavily reworked by the boffins at M. Naturally, the ride is firm, though in Comfort the body moves through its motions smoothly. 

The M5 is an effortless tourer, its eight-speed automatic shmoozing through ratios as it climbs and descends steep gradients. Wind and tyre noise insulation is good on coarse chip tarmac, though a bit more burble from the V8 would be appreciated. 

The M5 has nine adjustable parameters to wake it up: 'Drivetrain', 'Energy Recovery', 'Drivelogic' (gear shift aggression), 'Chassis', 'Steering', 'Brake', 'M xDrive', stability control settings and 'M Sound'. Favourite settings can be stored to the wheel-mounted M1 and M2 buttons. 

With the dampers still in Comfort the M5 remains fantastically capable with power delivery from the xDrive mighty rewarding on corner exit. Sport dampers sharpen the experience up further, amplifying the M5’s surprising agility. Thank the rear-wheel steer for this big sedan’s switchback performance. 

Step beyond the limit of grip, brake too late, or get on the power too early, though, and the M5’s mass reveals itself rapidly. It doesn’t help that the accurate steering is devoid of feel. The brake-by-wire pedal is too numb and light, as well, making it tricky to judge grip levels on the road.

Feel is less of an issue on a dry Mount Panorama circuit, where the M5 turns out to be a total pussycat. The all-wheel drive, consistent dynamics, strong brakes and well-tuned stability control make for an approachable but seriously fast sedan.

The responsive transmission will hold gears to redline and is eager on the downshift in its most aggressive setting while tactile shift paddles make commanding ratio changes yourself that bit more engaging. 

Prodigious punch out of corners is matched by the impressive consistency of the carbon ceramic brakes. The M5 pulled up for The Chase every time with minimal fuss, even from above 250km/h.

Similar credit goes to the 285mm front and 295mm rear Hankook S1 Evo tyres which remained consistent and predictable all day despite reaching temperatures over 130 degrees, according to the tyre pressure monitor.

I want to start this with just a small caveat. It hasn't been the most comprehensive drive of this car so far. And remember, there are a lot of variants.

Petrol, diesel, hybrid, two-wheel drive, all-wheel drive – we haven't driven all of them, and so I feel uncomfortable giving you my rock-solid verdict across the whole range. I can, however, give you my first impressions.

The first of those is that whoever in the vast Hyundai group came up with adding a long-hold function to the stereo mute button deserves a medal. By far the most annoying of the modern safety systems is the overspeed warning, which inevitably reads some signs incorrectly, others not at all, and has no idea when school zones actually start.

Thankfully, Kia, like Hyundai, now has the shortcut to mute it. You just long-hold down mute button and voila, the bing-bongs vanish.

Now elsewhere, as is pretty typical of modern Kias, the ride in this car feels properly well sorted. We've taken it through the city, onto the freeway, along a little twisting road section, and on some typically coarse and broken country B-roads, and the Sportage handled them all really well.

And even when you're getting a little frisky with the driving, there's little in the way of body roll, with the Sportage feeling planted and solid.

I wasn't totally blown away with the refinement in the cabin. On the wrong road surface, you definitely get a bit of road noise in the cabin – mind you, that is pretty hard to avoid on the coarse chip stuff – but you can also hear the engines revving away and working hard when you put your foot down.

That said, the way the gearboxes channel that power is smooth and easy, and when you put your foot down in each of the powertrains we tested, there's certainly enough urge to get you up and moving.

And that is especially true in the diesel, which I do think is a bit of a peach of a powertrain – super torquey and super easy to get the Sportage up and moving. It might find itself on the endangered species list, that engine, so get it while you can.

Now, one small downside. While the ride hasn't changed, at least for any of the ICE-powered cars, the steering has changed for all of them, and at speed, it's really lovely. It's quite direct, confidence-inspiring, and nicely weighted.

But at low speeds it can feel a little bit darty, like it takes a really big bite when you put a little input in, and it takes a little bit of getting used to.

All Sportage models start with seven airbags, and even the cheapest S gets a pretty full suite of safety stuff, including a new SOS button should you have an accident, auto emergency braking (AEB) with junction sensing, blind-spot monitoring, lane keep and lane follow assist, a rear-view camera and the often-infuriating speed limit monitoring.

From the SX+ and up you also get Kia’s Highway Driving Assist, which pairs active cruise with a lane entering function, and the GT-Line also gets remote park assist, which allows you to remotely drive into or out of tight spots, along with a blind-spot view monitor and a rear-view monitor.

The Sportage wears a five-star ANCAP rating, which it earned back in 2022.

In Australia, BMW has moved to match other manufacturers in offering a five-year/unlimited kilometre warranty on all its cars. 

Servicing is recommended on a condition basis, with the M5’s multimedia system prompting a visit to the mechanics. BMW offers pre-paid service packs for five years/80,000km at a price of $5059 for the basic offer and $8152 for 'Inclusive Plus', which covers brake pad and rotor replacements. 

It is expensive next to a regular 5 Series but when you consider the purchase price and performance level, the M5’s service pricing is not astronomical. 

All Kia models also get the brand’s seven-year, unlimited-kilometre warranty, seven years of capped-price servicing and, should you service with Kia, eight years of roadside assistance.

Turbo-petrol and hybrid models require servicing every 12 months or 10,000kms, where the rest are 15,000km intervals. The Kia website has the full costings for each powertrain choice, but for reference, seven years of hybrid ownership will cost you a not-insubstantial $4510.
