BMW X7 vs BMW M5

What's the difference?

When lined up against its direct rivals, the expensive X7 xDrive40d represents reasonable value for money.

It has a unique and bold look and a sumptuous, visually striking and well-appointed interior that has acres of space for family, friends, or for ferrying frequent flyers to the airport. 

That wallop of performance from the big beefy diesel is the cherry on the top. This is how you do a mid-life update. 

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.

There’s quite a bit that’s interesting about the X7’s design. Especially looking at it front on.

BMW certainly took a bold step when it introduced its toothy grille design for the X7 and the 4 Series range. 

But the Bavarian brand has made some even braver design moves recently by introducing a blocky front-end with split headlights on its new-gen 7 Series flagship sedan. That look has now found its way onto the face of the updated X7.

As with the 7 Series, it won’t be to everyone’s taste. But you can’t deny it has a lot of presence. 

The tail-lights have been tweaked and look good, but the sheer size of the X7 - it’s 5.2 metres long and 1.8 metres tall - means there’s no disguising the fact that it is a big, boxy SUV.

Inside the update ushers in significant design changes. The old dash and cowl is gone in favour of the ‘Curved Display’ that connects the instrument cluster and multimedia. 

New slimline air vents, LED backlit ‘X7’ graphics on the passenger side of the dash, and a new gear shift toggle that replaces the old shifter elevate the cabin and give it a much more modern vibe than the old X7 - one that’s in keeping with the excellent iX electric SUV.

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.

Regardless of the price point, a three-row SUV needs to be super practical and capable of family duties. 

And if you want a BMW X5 but need a lot more space, this is the next logical step.

Let’s start in the front row. As mentioned, the new X7 gains the screen and tech set-up from other new BMW models like the iX and updated 3 Series. The Curved Display combines a 12.3-inch digital instrument cluster with digital speedo and a 14.9-inch multimedia screen.

You can customise the cluster layout and move things around on the multimedia screen, too. The latter is a touchscreen but you can also find what you need via the 'iDrive' controller in the console.

I have had some experience with this system in the iX and while it’s not without its flaws, it is a top notch system. There’s a lot to wrap your head around, but the use of app icons helps. And you can swipe through to your chosen screen.

It took far too long to work out how to find the trip computer, something that should be much easier to access, as well as a couple of other functions. And the climate controls are housed in the digital screen. I would always prefer a separate space with buttons for air-con.  

But the graphics and displays - including the excellent head-up display - are excellent. 

Other tech you get with the X7 includes the BMW’s 'Digital Key', which is an app that allows iPhone users to lock and unlock their car remotely, and BMW ID driver profile.

If you buy this car, just allow yourself some time to familiarise yourself with all that tech.

Elsewhere up front there’s a lovely new three-spoke steering wheel, and cute touches like the metal air vent toggles, black and metal touches and the choice of inserts.

The front seats are luxurious and comfortable and offer loads of side and thigh support. They have memory functions, too. There’s no shortage of headroom up front, either.

Storage-wise, the door will fit the largest of bottles, as well as other items thanks to generous door bins, while the central lidded box is also sizeable. 

What about that second row?

The X7 xDrive40d usually comes standard with seven seats, but our test car was fitted with the $1500 captain’s chair option which drops seating capacity down to six people.

If you need the extra seating this is not the option for you, but it is great for families with bigger kids, and it would make for an excellent airport transfer car. 

The seats are unbelievably comfortable and can be adjusted to suit your preference. They also have ISOFIX points and armrests. 

Rear seat occupants have access to their own climate controls, air vents, USB ports, cupholders and ample door storage.

There is a massive amount of occupant space as well - stretch those legs out and enjoy it!

One of the X7’s selling points is that it is a genuine three-row SUV. That third row is not just for occasional use for very small children, like so many seven-seat SUVs. That row can be used every day. 

Even with my six foot stature, I could easily climb in and out of the third row. That’s made even easier thanks to the mechanical seat functions.

Just hit the lever at the top of the second row seat and the motor moves the seat forward and up to ensure there’s a big enough aperture to get in and out of the rear seats. 

You can also raise and lower the third row electronically via buttons on the boot wall - and they stow flush into the boot floor. Neat!

Once in the third row, there’s air vents, USB ports, bottle holders and storage and quite comfortable seats with more than enough leg and head room.

There’s even a third row section of the sunroof, operated from the second row. Lots of clever touches that people who use the third row will appreciate.

The boot has a few cool features, too, including a split tailgate.

You can even sit on the lower section - it can handle a load of up to 250kg - a perfect place to sit and watch the polo.

You can lower the suspension to aid loading larger items, and the X7 comes with a space-saver spare wheel.

Capacity is 300 litres with all seats in place, and I easily fit a pair of smaller suitcases in with that configuration. It increases to 2120L with the two rear rows folded. 

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 last M5 was well equipped but the new car is wanting for nothing. Australian cars have just about every option for $259,900, before on-road costs.

Australian M5s wear staggered 20-inch front and 21-inch rear alloy wheels paired with standard metallic paint, 'M Carbon Exterior' package (including carbon roof and rear lip spoiler), adaptive LED headlights and BMW’s 'Iconic Glow' illuminated kidney grille surrounds. 

Keyless entry, a heated steering wheel, heated and ventilated front seats, interior camera, powerful 18-speaker Bowers & Wilkins sound system, M seatbelts, four-zone climate control and a power tailgate are the cabin highlights. 

Optional extras are thin on the ground; you can choose from (eight) no-cost paint colours and all manner of 'Individual' shades (from $4100), four interior trims including classy 'Dark Oak' wood and four leather colours. There’s classic black ‘Merino’ leather, or you can have it dyed with a mix of 'Silverstone', red or 'Kyalami Orange'. 

Aside from that, the only major option is carbon ceramic brakes at a staggering $18,500, and an M5 Touring wagon costs $263,900. 

Though the M5 is more expensive than Audi’s closest rival, the RS6, the gulf isn’t huge considering you get a lot more punch in the BMW. Mercedes-AMG does not have an E-Class answer, yet.

Good value, then? Well, an equally potent Porsche Panamera is twice the price. So yes, in a sense.

The X7 xDrive40d is powered by a 3.0-litre, in-line six-cylinder turbo-diesel engine, that gets a boost in power - it pumps out 259kW of power and 720Nm of torque - 64kW/100Nm more than the 30d.

It now also comes with 48-volt mild hybrid tech, which uses an electric motor integrated in the eight-speed automatic transmission.

It drives all four wheels via BMW’s 'xDrive' all-wheel drive system and it is fitted with air suspension for a cushy ride. Towing capacity is rated at 3.5 tonnes braked or 750kg unbraked.

If you are keen on off-roading in the X7, it has a 221mm ground clearance, and a fording depth of 500mm, but maybe best to keep it on the tarmac.

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.

According to BMW, the official combined cycle fuel figure for the X7 40d is 8.0 litres per 100 kilometres.

Our fuel figure after nearly a week of mixed city, freeway and country driving was 9.0L/100km, which isn’t too far off the mark.

It has an 80 litre fuel tank and an approximate driving range of 1000km.

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.

With a big plush SUV like this, you’d expect a comfortable ride. And for the most part, the X7 delivers that, while offering more than a bit of grunt, as well.

The X7’s height ensures a high driving position, and there’s plenty of glass for decent visibility. 

Propelling a 2.5-tonne SUV could be a struggle for a lesser engine, but the meaty diesel offers ample torque and the mild hybrid set-up helps to reduce initial turbo lag significantly - that means it is responsive from a standing start.

I wouldn't have thought a vehicle of this size and shape was capable of a 5.9-second 0-100km/h time, but here we are.

As a result of all that torque and power, overtaking is a breeze - providing there is enough room on the other side of the road for both cars to fit.

That size and heft have an impact on cornering and dynamics. You simply can’t carve through tight corners in this car, but with that said, it’s more entertaining than you’d think. 

Steering feel is weighted on the heavier side and it’s as sharp as it needs to be in a car like this. It would be weird if the steering was too pointy. 

Ride quality is top notch - as it should be - and while the massive optional 23-inch wheels and low profile tyres mean you’ll notice potholes and the like, it largely soaks up imperfections with ease.

That level of refinement extends to the hushed ride, too. The cabin is a quiet and serene place to spend time - but not quite to the same degree as a 7 Series. 

Parking in tight spots is a challenge, and manoeuvring in narrow streets could take a while, too. But you could tell that just by looking at the X7.

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.

The regular BMW 5 Series range scored a maximum five stars in 2023 ANCAP safety testing but this does not apply to the M5.

The M5 features nine airbags and a host of active safety systems, including auto emergency braking (AEB), blind-spot monitoring, rear cross-traffic alert, lane-keep assist, auto parking and speed limit assist. 

Lane-keep can easily be turned off via two taps but the other systems require more menu navigation, though are mostly unintrusive. A 'Track' mode disables lane-keep, AEB and other systems along with switching the central display off. 

After copping a bit of flack from motoring media and buyers, BMW finally increased its warranty terms last year from three years to an industry standard five-year, unlimited kilometre warranty on its vehicles, including the X7.

Rather than a set servicing schedule, BMW offers condition-based servicing which is when the vehicle’s computer alerts the owner that it requires a service. 

BMW doesn’t offer capped-price servicing, but does have a pre-paid 'Service Inclusive Package' with terms ranging from three years/40,000km to five years/80,000km and beyond. 

A five-year basic package for the X7 costs $2800, which is not too bad considering the positioning of this model.

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.
