BMW M5 vs Hyundai Ioniq 5

What's the difference?

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 Hyundai Ioniq 5 Epiq N-Line AWD leverages an electric powertrain’s best attributes brilliantly well.

It’s ultra smooth and comfortable with ample performance and great dynamics thanks in part to this car’s N Line spec.

Its price tag pits it against formidable competition from the German Big Three, Tesla and others. But it has what it takes in terms of quality and value to fight that battle. It’s an impressive machine.

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.

Is this a big hatchback or a mid-size SUV? I’m on team hatchback, while Hyundai defines the Ioniq 5 as an SUV.

But who cares? They’re just words and the fact is even after close to three years in market this five-seater looks fresh and contemporary thanks to its confident, chiselled lines and wide stance.  

For car-spotters the N Line exterior treatment consists of flat aluminium badging, specific bumpers front and rear, with a deeper nose spoiler incorporating larger vents to cool the front brakes.

There’s also body-coloured cladding and side skirts, gloss black mirror caps, unique 20-inch alloy rims and a ‘hidden’ lighting signature across the top of the front bumper.

Inside there are Alcantara- and leather-appointed seats, an N Line-exclusive partially-perforated leather steering wheel, red contrast stitching and accents, and brushed metal covers on the pedals.

Add in the twin 12.3-inch screens display and this understated, super-cool interior comes to life with a sporty twist. 

The Ioniq 5 scores points for a manual dial for audio control and an Ioniq 5 update earlier this year included a row of simple-to-use buttons for the ventilation system and another on the centre console for seat comfort settings and more. A sensible blend of physical and digital controls.

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.

At just over 4.6m long, a little under 1.9m wide and a fraction more than 1.6m tall the Ioniq 5 comfortably fits the medium SUV profile.

But arguably its most significant dimension is a 3.0m wheelbase which is huge for a car of this size as evidenced by the wheels pushed out to the corners.

What that means is plenty of space inside, but before you can even get in the capacitive touch power door handles may look cool and help aero performance with their flush fit design but I’m not a fan. They’re hard to grip most of the time and don’t work well from an ergonomic point-of-view.

That said, once inside the front seats are adjustable six ways to Sunday and at 183cm tall I have plenty of head space and breathing room in general.

In terms of storage there are big pockets in the doors with room for bottles and thanks to the ‘shift-by-wire’ gear controller located on the steering column there’s room between the seats for a substantial console including a pair of cupholders, a slot for devices and a lidded tray (which doubles as a centre armrest) with that whole rear section able to swing up to allow access to a large lower shelf underneath.

In fact, the entire console unit easily slides fore and aft to liberate more legroom for the centre rear position. There’s also an oddments cubby in the lower part of the dash and a decent glove box.

Then, for connectivity and power there are three USB-C sockets (one in the dash switchable to streaming), a wireless device charging pad and a 12-volt outlet.

In the back that long wheelbase comes into its own. Sitting behind the driver’s seat set for my position I have loads of foot, leg and headroom.

Storage runs to door pockets with room for bottles, a fold-down centre armrest with a pair of cupholders, there are netted map pockets on the front seat backs and pull-up sun shades on the rear windows.

There are controls for the front passenger seat on the inner edge of the front passenger seat backrest which allows rear seaters to adjust its position. Thoughtful.

For power there’s a pair of USB-C sockets and individual ventilation controls in the back of the B-pillars is welcome. 

Then, not only is the electrically-adjustable rear seat split 60/40 in the backrest, it’s in the cushion, as well, which adds extra flexibility in terms of a balance between rear passenger space and room in the boot.

The boot is generous at 527 litres (VDA) with the rear seat upright and 1587L when it’s folded down.

There’s also a handy 24L ‘frunk’ under the bonnet, a decent portion of which is devoted to the (included) charging cable.

Interestingly, the Ioniq 5 AWD is rated to tow a 1600kg braked trailer with a trailer pre-wiring package standard. 

There’s a repair/inflator rather than a spare tyre, which is never a good thing, but there is a ‘smart’ power tailgate and a ‘Vehicle-to-Load’ function that allows you to power and/or charge three-pin appliances from the car. Handy.

It shows how far the Hyundai brand has come over its close to 40 years in the Australian new-car market that one of its five-seat SUVs wearing a price tag in excess of $90K doesn’t knock the Earth off its axis.

But a sticker price of $91,300, before on-road costs, does apply the pressure because it puts this primo Ioniq 5 Epiq N Line AWD in the same orbit as versions of the Audi Q4 e-tron, BMW iX3, Mercedes-Benz EQB, Tesla Model Y and Volvo’s XC40 Recharge.

In fact, our test car’s price includes the N Line Pack which is technically a $2500 option and its digital mirrors add a further $3000 for an as-tested price of $94,300, before on-road costs.

So, you should rightfully expect a handsome standard equipment list and this full-fat Ioniq 5 doesn’t disappoint.

Aside from the safety and performance tech we’ll get to shortly this car includes 20-inch alloy rims, all LED exterior lights (with auto LED projection headlights), dual-zone climate control, power driver and front passenger seats (heated/ventilated), heated rear seats, ambient lighting, a head-up display, wireless Android Auto and Apple CarPlay, Bose eight-speaker audio, digital radio, built-in nav and voice control for key functions.

There’s also Alcantara- and leather-appointed seat trim, BlueLink connected car services (with a five-year complimentary subscription), configurable ambient lighting, wireless device charging, a fixed glass roof, a heated steering wheel, heated and power-folding exterior mirrors, auto rain-sensing wipers, keyless entry and start, and ‘Remote Smart Parking Assist’.

That last one allows you to start and move the car forwards and backwards remotely (via the key) to insert it into or extract it from tight parking spots… or just impress your friends.

Suffice it to say the Ioniq 5 Epic N Line AWD stands up well against its competitors when it comes to included features for the money.

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 Ioniq 5 Epiq AWD is powered by a permanent magnet synchronous electric motor on each axle, both powerful, but the rear unit packs a bigger punch.

And combined peak outputs of 239kW and 605Nm are substantial with especially the latter delivering eye-widening acceleration.

Drive goes to all four wheels via a single-speed, reduction gear auto transmission on both axles. And a ‘Disconnector Actuator System’ is able to disengage the front wheels to reduce drag losses from the front motor and improve energy efficiency.

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.

The Ioniq 5 Epiq AWD is powered by an 84kWh liquid-cooled lithium-ion battery, borrowed from the high-performance Ioniq 5 N.

Thanks to 800-volt compatibility it can accept a 350kW DC charge which translates to an up to 80 per cent charge time of around 18 minutes, which expands to just over an hour using a more typical 50kW charger.

Connect to AC at the Ioniq 5’s maximum 10.5kW capacity and quoted charge time is just over six hours.

Official energy consumption on the combined (urban/extra-urban) cycle is 19kWh/100km and claimed range is a useful 495km.

Over a mix of urban, suburban and freeway running on test we saw a real-world average of 16.8kWh/100km, which is impressive for a car with this much performance potential.

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.

In terms of straight line performance we’re talking 0-100km/h in a tick over 5.0 seconds and I see anything in the five-second bracket as properly quick.

With more than 600Nm of peak pulling power at your disposal there’s always plenty of pulling power for efficient in-traffic moves and safe highway overtaking.

The shift-by-wire gear selector on the steering column takes some getting used to but once you’re in tune with it, it’s surprisingly convenient, especially during slow speed parking or turning manoeuvres. 

There are multiple modes - ‘Eco’, ‘Normal’, ‘Sport’ and ‘Snow’. Sport mode spices things up a bit with more urgent responses and the ‘HTrac’ AWD system uses multiple sensors to manage potential wheelspin and optimise drive in wet conditions or on loose dirt surfaces.

Suspension is by struts at the front and multi-links and the rear and the Ioniq 5 in this configuration is ultra-smooth and comfortable.

Even hitting pretty aggressive speed bumps and ruts in the road and the car soaks them up without fuss. You’re used to EVs being a little harsh in terms of ride compliance thanks to their relative weight, but that’s not the case here.

As part of a model upgrade introduced earlier this year Hyundai says it undertook a “comprehensive revision to the suspension tune”, which includes high-performance dampers on this N Line. And despite low-ish profile (255/45) Michelin Pilot Sport EV tyres on the 20-inch rims it remains comfortable and quiet.

The upgrade also included body reinforcements in the B- and C-pillar, door surrounds and under the body for a stiffer platform overall.

That pays off in the dynamics. Despite its 2.1-tonne weight the Ioniq 5’s steering is accurate and nicely weighted. It doesn’t feel lumbering or ponderous despite its relative heft.

The physical brakes are ventilated discs front and rear with regenerative available through four levels, the most aggressive setting being ‘i-Pedal’ which allows single-pedal driving.

It will slow the car to a full stop, harvesting the most energy possible in the process, although you might need a dab on the brake pedal if things are tight.

Miscellaneous observations include a 12m turning circle, so be ready for three-point turns where you didn’t think you’d have to.

Hyundai's (and Kia’s) default over-speed warning is present in full-force taking clicks through multiple screens to switch off and avoid its incessant audible alarm saying you've exceed what the car believes is the posted limit (every time you restart the car).

The recently released Tucson Hybrid features a short-cut function to do away with this issue and it would be welcome here.

The CPU underpinning the multimedia system is more powerful and response is speedy without a hint of lag.

And the camera based ‘mirrors’ take some getting used to. For many, they’re the answer to a question no one was asking. I mean, conventional mirrors work pretty well and any aero benefit from the smaller camera units has to be modest. But once you’re in tune with them the hi-def screens are excellent.

A flip of the switch on the interior rear view mirror allows you to side-step tall heads or loads in the back of the car but minimal depth of field is also (visually) awkward at first.

The Ioniq 5 received a maximum five-star ANCAP score from assessment in 2021, receiving its highest scores for adult and child occupant protection and the on-board safety assist systems.

The Ioniq 5 stacks up well relative to its competitors when it comes to safety. In fact, there’s so much crash avoidance tech on-board, courtesy of the Hyundai ‘SmartSense’ active safety suite, it would be straight up boring to list it all, but the highlights include AEB (with car-to-car, pedestrian and cyclist detection as well as junction turning and crossing functions), blind-spot monitoring and collision avoidance, lane keeping assist and lane departure warning, rear cross-traffic alert and rear AEB as well as active cruise control (with stop and go).

There are even more assists, warnings, monitors and alerts, but it’s important to note they (almost) all operate with relative subtlety. I did switch off the steering assist/lane-keeping functionality when it became confused and overly intrusive on twisting city curves.

If a crash is unavoidable, there are seven airbags on-board including a front centre bag to minimise head clash injuries in a side-on impact, as well as ‘Automatic Collision Notification’ and an emergency SOS call function operated through the Bluelink system.

For baby capsules/child seats there are three top tether points across the second row with ISOFIX anchors in the outer positions.

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. 

Hyundai covers the Ioniq 5 with a five-year/unlimited-km warranty, which is the mainstream market norm, with a separate eight-year/160,000km warranty for the drive battery; also an expected term.

Roadside assistance and sat-nav updates are renewed annually if the vehicle is serviced at an authorised Hyundai dealer.

Service interval is two years/30,000km which is appropriate for an EV given its relative mechanical simplicity and a ‘Lifetime Service Plan’ locks in scheduled maintenance costs for the life of the vehicle.

Service cost for the first five years is $1220, with each of the two services required in that time coming in at $610. Competitive for an EV in this part of the market.
