Ford Fiesta vs BMW M5

What's the difference?

The Fiesta ST is an addictive car to drive. It's a modern classic and hard to beat when it comes to engaging performance and smile-inducing dynamics. Add in excellent value for money and you have a certified performance car bargain. 

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.

The styling changes ushered in by the 2022 update are subtle. The Fiesta ST gains a revised front fascia with LED Matrix headlights, a larger grille with a repositioned Ford badge, and restyled bonnet and bumper. 

It gets a fresh 18-inch alloy wheel design and black tail-light surrounds at the rear. It also comes in two new exterior paint colours - 'Mean Green' and the 'Boundless Blue' of our test car.

The current-generation Fiesta ST has an appealing design that represents a clear evolution of its predecessor, and, arguably, it didn’t need much work this time around.

The ST’s sporty bodykit adds a touch of aggression but not in a boy racer sort of way. It’s a classic hatchback design with a bit of an edge. 

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.

As part of the update, the Fiesta ST gains new Recaro front sports seats that are firm and hug the body tightly. You feel well supported when cornering. The mix of synthetic leather and suede looks spot-on.

Like a number of sports-focused models, the ST features red stitching throughout the cabin - on the steering wheel, gearbox gaiter and air vent surrounds - and while it’s ubiquitous, it’s still a nice touch.

The chunky perforated leather steering wheel feels nice to touch, as does the metal gear knob. 

Cabin materials are a mix of soft-touch and hard plastics, and there’s carbon-fibre-look inserts on the dash.

There’s no denying Ford’s dash design is a huge improvement over the previous-generation Fiesta that ran from 2009, but the current model still lacks the polish of the VW Polo. It’s about on par with the Hyundai i20 N, although the Ford’s layout is a little busier.

In saying that, it’s hard to fault the cabin’s functionality. It has a deep central storage bin, which is larger than most cars in this category, a decent sized glove box, two-and-a-half cupholders in the centre console and storage for narrow bottles in the doors.

There’s a wireless charging dock behind the gear shifter, two USB ports (one in the storage bin and one next to the charger), as well as a 12-volt charger.

It’s nice to see the ST still has a manual park brake, too.

The facelift introduced a 12.3-inch fully digital instrument cluster, and while some may lament the loss of analogue dials, it’s nice to see Ford taking the opportunity to improve the tech.

The multimedia is housed in a smallish 8.0-inch digital screen sitting atop the centre stack and it runs Ford’s Sync 3 system. 

Sync 3 functions well, is hard to fault and the menu layout is easy to navigate, but it is being left behind by competitors with more modern and appealing graphics. The latest version in the new Ranger will no doubt be a major improvement, but we won’t be seeing it in this generation of Fiesta.

The diminutive size of the Fiesta ST is more apparent when sitting in the rear seats. It’s pretty tight behind my 183cm (6ft) driving position, with my knees hitting the rear of the front seats. 

It’s a cramped space that’s not designed for long trips by adults. It has redundant tiny rear-side windows behind the C-pillar, but on the plus side, there’s acres of headroom. 

It lacks rear-seat air vents and the closest USB port is in the front centre storage compartment. Taller bottles won’t fit in the doors and it lacks a centre fold-down armrest, but it has map pockets.

The rear seats are flat and the Fiesta has outboard ISOFIX points for child seats.

Realistically, most people buying a car like this aren’t using it to haul children around so think of it as a two-seater with handy rear-seat storage.

The rear seats fold 60/40 but not flat. A space-saver spare wheel lives under the boot floor and it has a high boot lip, meaning you have to lift items up and over to get them in. 

At 311 litres, it’s a decent sized boot with usable space. It’s just one litre more than the Hyundai i20 N, and six litres more than the Polo GTI.

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.

Under the Fiesta’s cute bonnet is Ford’s 1.5-litre three-cylinder turbocharged petrol engine delivering 147kW at 6000rpm and 320Nm at 4000rpm - the latter is an increase of 30Nm over the pre-facelift model.

Interestingly, it now matches the power and torque outputs of the Polo GTI. The i20 N pumps out 150kW and 304Nm.

The engine is exclusively paired to a six-speed manual gearbox - there is no auto transmission available - and it is front-wheel drive.

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.

Ford claims the Fiesta ST has an official combined cycle fuel use figure of 6.3 litres per 100 kilometres. 

After a week of predominantly inner city and freeway driving, we recorded a much higher 10.2L/100km. However, that was very shortly after an enthusiastic back-road blast to test its performance chops. We did see single-digit numbers throughout the week prior to that.

The Fiesta requires premium 95RON petrol and it has a 45-litre tank. CO2 emissions are 144g/km of CO2.

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.

It’s easy to find your ideal driving position in the Fiesta ST, thanks to the reach and height adjustable steering wheel and the adjustable seat.

Aside from the extra 30Nm dollop of torque, Ford hasn’t changed anything else about the Fiesta ST mechanicals for 2022, but arguably, it didn’t need to.

The pre-facelift model could cover 0-100km/h in 6.7 seconds, and while Ford has not revealed whether that has changed with the facelift, it feels about right.

It’s brisk from a standing start, without being neck-snappingly quick, but there is strong urge and a lack of noticeable turbo lag. There is, however, some axle tramp on take-off, particularly in the wet. We also detected some torque steer when pushing hard up a hill, but it was minimal. 

Speaking of, the little three-pot turbo engine is utterly unfazed by steep hills - it just keeps adding speed. A light kerb weight of 1218kg helps here. 

The three-pot turbo engine sounds wonderful when accelerating, and the Fiesta ST begs to be driven hard.

The engine is perfectly matched with the slick shifting six-speed manual gearbox that has lovely short throws and is a joy to use. Even if Ford offered an auto with the Fiesta ST, it would take away from the driving experience.

'Sport' mode ups the growl from the engine and throttle response, but it’s not a dramatic departure from 'Comfort' mode.

The ST’s strong brakes are bordering on sensitive, but the heavily weighted steering is incredibly sharp.

On a back road run, the front-wheel drive Fiesta ST comes alive, hugging corners confidently. 

On bends that would’ve seen many other cars come undone, the Fiesta’s tight, balanced chassis, grippy tyres and the standard mechanical limited slip differential ensure it maintains its composure.

The ride is undeniably firm, particularly around town in urban areas - you feel every speed bump. My partner found the ride a bit too much at times, but I was far more forgiving.

The Fiesta feels solidly built and has a level of refinement that’s missing from the likes of the Suzuki Swift Sport and Hyundai i20 N.

However, the cabin could do with more noise deadening materials as it can be quite rowdy at speed and on coarse chip roads. Another negative is the massive turning circle - a bit odd for a city-focused light hatchback.

But these are things I could happily live with. During my week with the Fiesta ST, I made any excuse to jump behind the wheel and go for a drive.

Me: “I’m just going to run to the shops to get pasta.”

My partner: “We’re not cooking pasta this week.”

Me: “Yeah but you never know when you need pasta. Bye!”

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. 

The Fiesta is covered by Ford’s five-year/unlimited kilometre warranty and you get free roadside assistance and state/territory auto club membership each year that you service your car at a dealer, for up to seven years.

The servicing schedule is every year or 15,000km, whichever comes first. There’s a four-year/60,000km capped-price servicing program, which costs $299 per service. 

Ford also offers a free service car loan that can be booked in ahead of your service.

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.
