Alfa Romeo Giulia vs BMW M5

What's the difference?

The Giulia is a love letter to the increasingly lost art of the sporty executive sedan. As refined as it is beautiful and oh-so elegant to drive, it’s a reminder of why we always love Alfa Romeo, even when the odds are against it.

Emotional cars like this are hard to come by and they will soon be gone, replaced by something new. The future is not necessarily worse, but it will be different, so if a sporty European sedan with a combustion engine is calling out to you don’t miss your opportunity to drive the Giulia while it still exists in this form.

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.

Like any good Alfa Romeo should be, the Giulia is a work of art. It’s sleek, sharp, and immaculately proportioned.

This most recent update has artfully refined a formula too good-looking to mess with. The increasingly dorky headlamps from the previous car have been swapped out for a more contemporary all-LED set, with a three-bar DRL pattern.

The grille has also been tweaked for this update for a more modern style, and the Veloce is now graced with the iconic and more aggressive sport two-tone alloy wheels in the traditional five-hole 'tele-dial' style.

It’s effortlessly attractive, and instantly recognisable as an Alfa on the road. I can’t think of a better way to stand out in today’s executive sedan landscape.

The interior has received less of an upgrade for the 2024 model year, with the same core parts. The major change is the old-school analogue instrument cluster being swapped out for a slick 12.3-inch digital unit.

The puzzling thing about this is the 8.8-inch central multimedia screen hasn’t been upgraded in-kind, making a strange contrast between the sharp and fast digital instruments, and the laggy and dull multimedia panel.

At least it effortlessly sits behind the curvaceous design of the dash as to not interrupt a good shape.

There are of course plenty of other touches which I love. The leather seats look and feel the part, as do the real metal paddle shifters which float behind the simple yet refined and sporty steering wheel.

The push-to-start button on the wheel is reminiscent of other Italian sports machines, while the tasteful smattering of leather, gloss plastic, and textured surfaces keep the premium feel on-track.

Some areas I’m not so keen about: Some of the interior plastics, particularly for buttons and toggles, feel cheaper than they should, and the door cards are oddly basic considering how much attention has been given to every other part of this car’s look and feel.

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.

The Giulia is an old-school low-slung sports sedan. Many will prefer the SUV sensibilities of the Stelvio, with its bigger hatch-opening boot, and its higher ride height can better accommodate less mobile passengers, and makes it easier to fit child seats and the like.

For those willing to trade those things away for a superior drive experience, the Giulia is still solid to live with every day, but has a few drawbacks.

For example, those strangely basic door cards offer only a tiny map pocket with a nook I’d hardly describe as a bottle holder.

The centre console offers two larger bottle holders with variable edges, but there’s also not much else in the way of storage in the cabin aside from a smaller-than-average glove box and armrest console box.

The big win for me is the physical dial set and shortcut buttons for all the key climate functions, making it easy to operate while you’re concentrating on driving.

At least the seats are well bolstered, and front passengers are treated to plenty of adjustability. Visibility is okay, and it was easy for me to find a comfortable driving position at 182cm tall.

The rear seat is a similar story. It’s tighter, and you have to duck down below the roofline to get into it.

Once inside, I was pleasantly surprised to find enough room for my knees and somewhere for my feet to slide behind my own driving position, although the centre position is all but useless thanks to an enormous raise for the driveshaft.

Headroom is passable, but you wouldn’t want to be much taller than me. 

There are, again, tiny bottle holders in the doors, and a further two in the drop-down armrest. Rear seat passengers get dual adjustable air vents on the back of the centre console, one USB 2.0 outlet, and elastic nets on the backs of the front seats.

The boot measures 480 litres which is up there with a lot of mid-size SUVs, but because it’s a sedan, access is more limited, and it won’t accommodate as many awkwardly-shaped objects.

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 Veloce might not pack a Ferrari-derived six-cylinder engine like the Quadrofoglio, but its smaller 2.0-litre four-cylinder turbocharged petrol engine hardly wants for power.

Packing 206kW/400Nm it outpunches six cylinders of old easily, and is still capable of sprinting to 100km/h in a hot-hatch baiting 5.7 seconds to a Vmax of 240km/h.

It even sounds fantastic, as it flies up the rev-range living up to every bit of the Alfa promise. Peak power arrives at 5250rpm, but peak torque hits at 2250rpm.

Smooth shifts are provided courtesy of an eight-speed traditional torque converter automatic transmission.

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 2.0L turbocharged engine has an official combined cycle fuel consumption figure of just 6.1L/100km, although I saw 9.0L/100km in my time with it.

I’ll admit it was being enthusiastically driven, and treated to lots of urban commuting.

The Giulia has a 58-litre fuel tank and requires mid-shelf 95 RON premium unleaded fuel. Its approximate range on a full tank at the official consumption is 951km.

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.

Put simply: The Giulia is a celebration of Alfa Romeo. Yes. Even with a humble 2.0-litre turbocharged engine and an automatic transmission, this is a deeply emotional car. A riveting experience from behind the wheel.

Fly round corners, your eyes wide, exclaiming ‘magnifico!’ as the Giulia gracefully leans in, the rear LSD, sporty tyres, and wonderfully tight steering working together in harmony as you eke out just a smidge of tyre roar.

Laugh out loud to yourself, as you plant the accelerator, hear the muted rumble of the surprisingly angry little engine, and feel the turbocharger kick in half a second later as you power out.

‘Eccezionale!’ You’ll think, as you feel the click of the immensely satisfying metal paddle-shifters, and the transmission responds in-kind, the engine roaring up the revolutions with enthusiasm.

Sure, the Veloce grade is not as raw, or as wild, or near as fast as the top-grade Quadrofoglio, but all of the exciting spirit of  that car is still here, and at a little over half the price, too. The Veloce is an absolute delight to drive.

It has such poise, makes such a fine sound, and does it all so gracefully. This is how you make a car feel as one with the driver.

Even the ride is deeply impressive. It’s not too harsh or noisy, while gifting the chassis just the right amount of lean in the corners and allowing enough play for it to remain controlled over bumps.

Not only does it work well when you’re driving as it's clearly intended to be driven, but around town it’s quiet and refined inside, living up to the promise of a luxury sedan.

The seats and bolstering are great, the visibility isn’t too bad, and while I’ll complain about the slightly laggy software on the multimedia screen, the digital dash is responsive and the physical climate controls are welcome.

It’s not all perfect. If it were, I think it might cease to be an Alfa Romeo and start sprouting BMW badges.

For example, our test car, with less than 2000km on the odometer, had various inconsistent rattles emanating from the plastic garnish around the digital dash, and somewhere behind the back seat.

Regardless, driving this car has made me a little sad Alfa will be putting this wonderful platform behind it in pursuit of more electrified goals.

I can only hope wherever the Giulia nameplate goes next, it retains the spirit of this version.

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. 

Alfa finally updated its warranty to a more industry-standard five-years and unlimited kilometres in 2022.

Service intervals occur at 12 monthly or 15,000km intervals for the 2.0-litre turbocharged variants. Pricing was not available for the model year 2024 version yet in the brand’s online calculator, but to give you an idea for the pre-facelift version, pricing came in between $345 and $1065 per visit, averaging $573 per year for the first five years of ownership. Not cheap, but not as expensive to run as you might expect.

One thing you might want to keep in mind is depreciation. Boring, I know, but even late model examples of the Giulia and Stelvio have been hit particularly hard by the depreciation stick according to residual values we searched up on Autotrader.

For reference, the Genesis G70 and BMW 3 Series have both fared much better in equivalent 2.0-litre turbo forms.

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.
