Ferrari Roma vs BMW M5

What's the difference?

The Ferrari Roma is like a trained assassin in a Zegna suit - capable and clinical yet stylish and effortlessly superior. We believe there’s a replacement coming later this year and it will have to be doing well to top this superb machine.

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. 

Note: CarsGuide attended this event as a guest of the manufacturer, with meals provided.

If you’re looking for a flash Fazza with spoilers and vents at all points of the body, you’ve come to the wrong coupe.

The Roma is a subtle, beautifully balanced and delicately detailed two-door inspired by all-time Ferrari classics like the 250 GT Lusso and 275 GTB.

Its proportions are impeccable with complex curves and sweeping lines combining to produce an exquisitely pure shape.

Slimline LED headlights are divided by horizontal DRL strips, the broad bonnet incorporates a quietly muscular power bulge and the minimalist ’egg crate’ grille sits below a sharply chiseled nose.  

I’m a particular fan of the split wedge-shaped tail-lights, seamlessly incorporated into the upper deck of the rounded rear end. The active rear spoiler is also neatly hidden away in the leading edge of the boot lid. No shoutiness here, even the exterior badges are works of art.

Crack open the bonnet and the engine sparkles like a jewel in a display case. Scarlet red crackle finish on the intake plenums and cam covers make it pop like a firecracker. 

The interior follows a dual cockpit theme with twin curved sections divided by a flying buttress style console between them housing the gear selection gate and central media screen.

Flashes of carbon-fibre and chromed alloy add a touch of overt raciness, Alcantara on the dash and doors echoes the ‘mouse fur’ of Ferraris past and the contrast stitching around the cabin is flawless. 

The sleek front seats feel as good as they look, the typography of the Roma badge on the passenger side of the dash is super cool, and overall the interior is snug and ultra classy. 

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.

At close to 4.7m long, the Roma isn’t compact but its supercar stance comes courtesy of a close to 2.0m width and low-riding 1.3m height (with a 2670mm wheelbase).

The cabin is cozy, as intended, but at 183cm I still have ample headroom in the front. The rear is a different story with the two ‘+2’ seats serving as occasional emergency spots only or a handy option for smaller kids.

For storage there are slim but long pockets in the doors, a surprisingly generous glove box, a wireless charging pad under the centre console, phone-size slits on either side of that console, a single cupholder between the front seats with a lidded box (containing 12V and USB-A outlets) behind it.

There’s a recess for oddments on the transmission tunnel between the rear seats, and armrests either side in the back.

The boot holds 272 litres, which is enough for several soft bags, rising to 345 litres with the 50/50 split-folding rear seatbacks lowered. There are tie-down anchors, which is handy but be aware there’s no spare, only a repair/inflator kit.

Overall, not exactly SUV-like in terms of day-to-day practicality but at least on par with its key competitors.

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.

Enzo Ferrari famously said “aerodynamics are for people who can’t build engines” and notwithstanding the fact the Roma is slippery in the wind tunnel (Cd .30), its front-mid mounted 3.9-litre turbo-petrol V8 engine would surely meet with il Commendatore’s approval.

Sending drive to the rear wheels via an eight-speed dual-clutch auto transmission, this all-alloy, 90-degree unit features dual twin-scroll turbos, a flat plane crank, dry sump lubrication, direct fuel-injection and a single-piece cast exhaust manifold to produce 456kW from 5750rpm to the 7500rpm rev ceiling, and 760Nm from 3000-5750rpm.

Worth noting its 'front-mid' placement as the entire block is positioned low down and behind the front axle centre line.

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 Roma’s official (WLTP) fuel consumption figure on the combined (urban/extra-urban) cycle is 11.2L/100km, the 3.9-litre turbo-petrol V8 emitting 255g/km of CO2 in the process.

Not exactly miserly, but even with that engine begging to be revved we saw an average of 12.9L/100 over a combination of urban shuffling, twisting B-roads and some freeway running.

A start/stop function is standard and with an 80-litre fuel tank on board, the Roma’s theoretical range is around 715km, dropping to approximately 620km using our real-world number.

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.

Press the PS (Partenza Sportiva) button on the console, slip the manettino control on the steering wheel into ‘Race’ mode, left-foot brake (hard) and floor the throttle. Wait for the PS light on the dash, keep the accelerator pinned and lift off the brake.

Ferrari says the Roma will then proceed to accelerate from zero to 100km/h in 3.4 seconds, and in the interests of a thorough assessment I may have found a quiet light commercial area near Maranello, replicated this procedure and validated the claim.

Yes, even at 1570kg, with 760Nm of pulling power available from 3000-5750rpm, the Roma is exceptionally fast in a straight line. And the twin-turbo V8 that’s been so reserved and docile around town lights up to deliver glorious engine noise and a characteristic exhaust howl.

A flat-plane crank arrangement often makes a vee engine lumpier than a more conventional cross-plane design, but it will rev hard and fast, and in this case the compact size of the Roma’s twin turbos enhances throttle response even further.

Speaking of the turbos, variable boost management helps to smooth acceleration while keeping an eye on fuel economy and despite the flat-plane configuration this engine is perfectly civilised.

A tall top (eighth) gear makes for easy cruising but the tight B-roads and lesser highways we spent most time on didn’t allow for any high autostrada speeds.

But how’s this for a flex? Ferrari says the active rear spoiler will stay in its low-drag position until the car hits 100km/h, then pushing through medium and high drag (135-degree) positions as speed rises. But… “over 300 km/h, the spoiler is always in MD mode because in such conditions it is preferable to have a more balanced car”.

Suspension is by double wishbones at the front with a multi-link set-up at the rear and twin solenoid (magnetic) adaptive dampers all around.

Rubber wrapping the 20-inch forged alloys is top-end Michelin Pilot Sport 4 S (245/35 fr / 285/35 rr) and front-to-rear weight distribution is 50/50.

What that all adds up to is a comfortable, responsive and deeply satisfying drive experience. In standard Ferrari fashion the dual-clutch transmission is rapid-fire perfection, the steering is light but accurate and feelsome, while the in-cabin ergonomics are superb.

Push as hard as you dare in tight, flowing corners and the car just continues to grip and bait you to try harder. And if you do give in and start to run out of talent the ‘Active Yaw Control’ and limited-slip ’E-diff’ will step in to imperceptibly save your bacon.

Moving the manettino through its five positions - ‘Wet’, ‘Comfort’, ‘Sport’, ‘Race’ & ‘ESC-Off’ rapidly transforms levels of ride comfort, steering, transmission and engine response. You can also set the ride to Comfort with other attributes dialled up to 11 for a cross-country sweet spot. 

And when it comes to slowing rather than going, the Brembo brake set-up is circuit ready with vented carbon ceramic rotors all around (390mm fr / 360mm rr) clamped by six-piston calipers at the front and four-piston units at the rear. They take a while to warm up, but never feel anything other than mega. 

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. 

As the name implies, Ferrari’s ‘7-Year Genuine Maintenance’ program means you won’t have to worry about servicing costs for the first seven years of ownership. Everything from labour and parts to lubricants and brake fluid is included in the free-of-charge package.

For reference, maintenance is recommended every 12 months/20,000km, which is a healthy distance and roadside assistance is complimentary for the first 12 months. 

Warranty cover is three years/unlimited kilometres, which trails the mainstream market but matches high-end competitors like Aston Martin, Lamborghini, McLaren and Porsche.

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.
