What's the difference?
Balancing luxury car comfort, hot hatch agility and supercar speed is no easy task, yet that is what made the six previous generations of BMW's M5 so iconic.
In seventh-generation ‘G90’ guise, the M5 has another skeleton in the cupboard: the toughest emissions regulations that Europe, and now Australia, have ever seen.
A twin-turbo V8 was untenable and going battery electric was not an option. Plug-in hybrid was the only answer. For the new M5, BMW combined a revised 4.4-litre ‘S68’ bent eight with a punchy electric motor for 535kW and 1000Nm.
Problem is, the G90 is widely acknowledged as one of the greatest BMW M cars of all time, especially in CS trim. And thanks to a circa-600kg weight hike to nearly 2500kg, the new M5's 0-100km/h claim is actually slower than the old 'F90' M5.
Doesn’t exactly sound like a big leap forward, does it?
A drive through the Central West of NSW and around the iconic Mount Panorama racing circuit gave us answers to two questions. Does the M5 work on Australia roads, and does BMW M's latest super-sedan represent progress?
Lamborghini is a brand built on madness, excess and eye-searing design. Its cars don’t have to make sense, and indeed its owners probably prefer it if they don’t - they have other vehicles to use for the real world.
So, the existence of the new Lamborghini Huracan Sterrato, the world’s first 'All-terrain Supercar', a V10-engined mad machine built to drive sideways at high speed on dirt, should not come as a surprise.
And yet it really does, because there’s never been anything like it before (yes, Porsche has built the 911 Dakar, but it’s more of a sand-dune-climbing, desert-crossing motorsport tribute), for the very good reason that no one ever considered it would be a good idea.
It also sounds just a touch intimidating, the kind of driving experience that would require pro rally driver skills to survive, so it was with some trepidation that we headed to Palm Springs, USA, to test out the new Huracan Sterrato.
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.

Not just a spectacularly stupid idea made real, the Lamborghini Sterrato is by far the best, or at least most hilarious, of the many Huracan variants the company has produced.
It makes you feel like a hero, even when you’re going sideways on dirt like a nutter. It could just be my new favourite supercar.

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.
Oh yes, it’s pretty interesting, all right, because it breaks new dusty ground for Lamborghini, and its Huracan in particular.
To cope with its intended use, the Sterrato has been raised 44mm higher than the ground-hugging normal version and it’s also had giant, bolt-on style guards attached to make it look a bit wilder.
Also quite noticeable is the huge roof scoop - which renders rear vision from the driver’s seat a complete zero, they may as well throw the mirror away - which has to be there to help the V10 engine breathe.
The side air intakes through which air usually gets to the mid-mounted power plant have been blocked up, because they would have sucked in too much dirt and gravel.
I’m happy to report the silly looking rally style headlights stuck to the Huracan’s shark nose are optional, although again, no doubt every buyer has gone for them, because they stand out in a crowd.
The Huracan Sterrato has no problem doing that on its own, of course, because it already looks extremely aggressive, and its knobbly, all-terrain tyres finish off that style flourish.
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.
Next question, please. You don’t get cupholders, there’s not really anywhere to put your phone and the cabin generally feels as roomy as a phone box that’s been through the wash and shrunk quite badly.
There’s a frunk that can barely hold two small backpacks and that’s about it. If you want practical space, buy an Urus. The Huracan Sterrato is not a practical car, but that’s not part of its design brief.
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.
Well, considering every Lamborghini Huracan Sterrato will almost certainly go up in value and become a collector’s item you’d have to consider them good value, at least in investment terms.
On the other hand, any car with a price tag of $503,949, before on-road costs, sits somewhat adjacent to the word “value”.
That large number has not put enthusiasts off, however, with all 1499 of the limited-run Sterrato Huracans already sold, and a long list of people with their names down hoping that someone gets scared and changes their mind, apparently.
Our vehicle came with two built-in cameras, which you could operate through the touchscreen to record Tik Tok-length videos of your driving.
This is almost certainly a cost option, but no one could tell us exactly, and all of the cars are already sold, no doubt to people who ticked every single option box.
Oh, and you do get aluminium floor mats. Nice.
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 Sterrato is powered by a Lamborghini engine that’s on its way into the history books, a 5.2-litre V10 that will die with this, the last variant of the Huracan.
Its replacement will be powered by a V8 hybrid, which will no doubt be more powerful but simply will not sound as amazing.
The version in the Sterrato has been detuned slightly, partly because of the breathing issues - you just can’t get as much air into an engine when it’s driving through its own self-propelled dust storm - and because of its all-terrain tyres, the first ever to be speed rated to 260km/h.
It still makes an impressive, and very loud, 449kW (602hp) and 560Nm, however. I’d describe it as “more than enough”.
That monster engine is matched with a seven-speed dual-clutch automatic and a very, very clever all-wheel drive system.
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.
So, Lamborghini claims the Huracan Sterrato will deliver a fuel "economy" figure of 14.9 litres per 100km, which seems like a lot, until you consider it probably won't get anywhere near that, if you drive it the way you're supposed to, particularly foot flat and wheels spinning on dirt.
Again, fuel economy is not a core value for this car, nor its buyers.
An 80-litre tank means a theoretical range of around 480km.
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 could give you the short version of what it was like to drive the Lamborghini Huracan Sterrato at speed on a specially prepared dirt race track, which would be to say that I have never, ever had so much fun in a car, but that would be selling it short.
While the Sterrato is clearly built to do one insensible thing brilliantly, while somehow not imperilling the life of its driver, what is most incredible about it is how good it is at everything else, as well.
To create this Huracan, Lamborghini had to increase the ride height significantly, soften up the suspension and increase its amount of travel.
It also had to ask Bridgestone nicely to produce a tyre unlike anything the world has ever seen, an all-terrain tread capable of dealing with dirt and gravel and yet also grippy enough to be used on a sealed race track, or to carve up your favourite mountain pass.
It also had to be capable of being speed rated to 260km/h, or about 100km/h faster than any all-terrain tyre Bridgestone has ever produced before.
Looking at the unique Dueler All-Terrain AT002s, with their chunky tread, you would assume that the Sterrato is going to be noisy, slippery and possibly a little rough on public roads, but that’s not the case at all.
This Huracan rides more smoothly - largely thanks to those suspension tweaks - and more quietly than its forebears, and it’s actually more practical around town as well, thanks to the ride height. So, no more flinching at speed bumps.
The tyres also provide proper supercar levels of grip on public roads, even those dusted with a bit of desert sand.
There’s a bit of squirm at the rear and under hard braking, but overall the experience is typically Lamborghini Huracan wonderful, all playing out to a soundtrack that is beyond beautiful from that howling V10.
The first part of our track experience at the Chuckwallah Raceway was also familiarly fantastic, the Huracan ripping around the sealed track at astonishing speed; it certainly doesn’t feel detuned.
Lamborghini had gone to the trouble of mirroring the sealed circuit with a specially constructed dirt track in the infield, so that 50 per cent of our lap would be spent sideways in ankle deep, dust, sand and rocks, much of it through long, long bends, with the occasional chicane set up specially for Scando flicking action.
Now, I am not, by any means, an expert at drifting, nor an accomplished rally driver, so I was, to put it mildly, shit scared of getting this half-million-dollar, limited-edition, 449kW monster on to the dirt section.
I feared I would spin around, or flip upside down, or find some other way to embarrass myself, but what happened when I got there was beyond inexplicable, and beyond joy.
This car is so clever, so easy to drive, so beautifully balanced, that it can turn a total newb into Colin McRae. His name comes to me because the whole experience reminded me of driving a rallying video game, it felt unreal, and yet overpoweringly visceral at the same time.
I could start a drift with the slightest flex of the throttle, then balance the car as it pivoted around a bend before nailing the throttle and haring off to the next fantastic drifting opportunity.
When we got back on the sealed stuff, the car would shake like mad, at 200km/h, as the dust attempted to get its way out of the wheels, but that just added to the excitement.
The secret wasn’t that I’d somehow become a better driver, it was what Lamborghini engineers call, accurately, “the hero maker”.
It’s a software and hardware package called LDVI, or 'Lamborghini Dinamica Veicolo Integrata', which, when you put the Sterrato in 'Rally' mode, uses many sensors combined with torque vectoring and selective braking to keep you going where you want to go, with minimal intervention.
Or at least minimal intervention that you can feel, which makes you feel like a hero.
I kind of understand how it works, but I totally relate to how it makes you feel. Like a genius. And you’d pay $500K for that, surely?
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.
In a V10-engined supercar you’re meant to drive on dirt? You’ve come to the wrong place.
Okay, so there’s no crash rating, and there won’t be, but you do get AEB, driver, passenger, and side airbags along with knee airbags as well as front and rear-specific collapsible areas, reinforcement bars in the doors. Oh, and Electronic Stability Control.
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.
The Huracan Sterrato comes with a Lamborghini warranty good for three years with unlimited kilometres.
It also comes with 24/7 roadside assist for an unspecified amount of time. It is also offered with pre-paid scheduled maintenance service for three or five years.
