Gac M8 vs Hyundai Ioniq 6

What's the difference?

The GAC M8 PHEV Luxury is a people mover that carves out a very specific niche, largely thanks to its plug-in hybrid powertrain and ambitious price point. It’s undeniably well specified and genuinely luxurious inside, but it never quite escapes its chauffeur-like identity as it's a vehicle built around passenger comfort rather than driver engagement.

Being a new brand in our market limits ownership appeal, at least for now. Where the M8 really impresses, though, is efficiency, and that alone may be enough to justify its unusual positioning.

The Hyundai Ioniq 6 will stand out in any automotive crowd, thanks to its distinctive aero-influenced design.

It’s well-equipped for the money, surprisingly roomy, energy efficient and notwithstanding some niggles around the ride and steering feel, comes up to scratch dynamically.

Does it do enough to apply the thumb screws to the likes of Tesla's Model 3? I think it’s got a pretty good shot, and it will be interesting to see if EV buyers embrace the car’s unusual streamlined look.

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

The GAC M8’s design is… well, it’s out there. This isn’t a people mover that fades politely into the background. There are clear parallels with the Lexus LM, right down to the towering grille (complete with a vague hint of spindle shaping), which may well be the tallest grille I’ve encountered!

It’s a big unit, too, measuring 5212mm long, 1893mm wide and 1823mm high. The overall shape is sharply squared-off and prioritises presence over dynamism. It also comes standard with a full suite of LED exterior lighting.

The cabin claws back some design cred, though, as it’s downright plush with its semi-aniline two-tone leather upholstery - finished in a lush burgundy/black duo in our test vehicle. Accent panels vary between a diamond-design for the dashboard and doors, to suede soft-touchpoints and rose-gold inserts liberally scattered across the cabin. 

The only accent that doesn’t land is the large swathes of piano black on the centre console as it’s hard to keep clean.

There are some nice little surprises, too, like the fidget spinner-style crystal gear lever, which is surprisingly fun to fiddle with at traffic stops and two sunroofs with the rear fixed panel illuminating with internal ambient light.

Some of the finishes aren’t the best as there are joinery and door handles that don’t line up properly, which is surprisingly more annoying than you’d think once you notice it. But overall, the cabin feels well-considered and luxurious, even if the execution isn't always flawless. 

Lots of cars are said to be “shaped by the wind” but all you have to do is look at the Ioniq 6 to know that in this case it’s 100 per cent true.

In fact, images of the car in Hyundai’s wind tunnel show it performing more like a perfectly shaped wing than a four door sedan.

With a drag co-efficient (Cd) of 0.21 it’s slicker than the ultra low-drag Tesla Model 3 and Porsche Taycan. And while not conventionally pretty it’s certainly a striking and unusual design.

Flush door handles? Of course. Carefully sculpted spoilers front and rear? Yep. Active air flaps? Check. The RWD Dynamiq’s 18-inch alloy rims are shaped for aero efficiency, while the top-spec Epiq grade even swaps out conventional side mirrors for super-cool digital cameras and interior OLED screens.

And the sleek looks continue inside with a two-section dash divided horizontally by a swoopy winged insert and topped with a pair of 12.3-inch screens covering multimedia and instrumentation.

The look and feel is minimalist. A lot of the controls are on screen or digital, but a physical dial for audio volume gets a big safety and convenience tick. 

No gearshift in the bridge-like centre console. A rotary stalk is located behind the steering wheel on the right-hand side.

There’s configurable ambient mood lighting with six pre-selected themes and the materials used inside are suitably eco-friendly.

Cloth seat trim is recycled PET plastic, as is the headliner, the dashboard skin is manufactured using bio-ethanol, the carpet is made from recycled fishing nets (!), and bio paint (partially derived from vegetable oils) is used on the doors. 

Yes, there’s leather, but its dyeing process uses biodegradable flaxseed oil rather than conventional pigments, which is a good thing in terms of fewer harmful microorganisms in waste water, and is claimed to reduce CO2 emissions by 3.8kg per car. 

On the outside, recycled pigment paint made using ‘end-of-life’ tyres is applied to the body cladding, and bamboo charcoal pigment paint is used in the ‘Digital Green’ pearl colour option.

Speaking of which, there are seven other colours available; three more pearl shades - ‘Abyss Black’, ‘Ultimate Red’ and ‘Biophilic Ink’, as well a single metallic ‘Nocturn Gray’ and a solid ‘Byte Blue’. ‘Gravity Gold’ matt finish is the only extra-cost choice at $1000. 

The front row has plenty of space and the seats feature heating and ventilation, making longer journeys comfortable. However, there’s no extendable under-knee support and only the driver gets lumbar adjustment. I’ve spent much of the week feeling like a chauffeur, as my husband and child insisted on sitting in the back!

The middle row is where the M8 really shines. The captain’s chairs are indulgent, offering full recline, footrests, heating, ventilation, and massage. Comfort is excellent, though the footrest extension limits space for the third row, and even at 168cm I found it a snug fit when fully reclined. Access is straightforward with grab handles and a low 143mm step-in height, though be mindful of kerbs as the doors aren’t forgiving when it comes to tall council strips.

The third row is one of the few that genuinely accommodates adults. Head- and legroom are ample, and the seats feel firm but comfortable, especially with the foldable armrest. Amenities aren't forgotten with four cupholders, two USB-A ports and directional air vents. Access requires sliding through the middle row, so it’s best if those seats are unoccupied, but otherwise it’s not too taxing.

Front-row storage is practical, with a mid-sized glove box, dual-opening middle console, cupholders and a clever phone cradle that integrates a wireless charging pad and cable routing for a tidy set-up. There’s also a USB-A and USB-C port and a 12-volt socket in the large shelf underneath the centre console.

The middle row enjoys three USB-A ports, a USB-C port, directional air vents, retractable sunblinds, tray tables (though not usable while driving) and climate control. Storage is decent, with six cupholders, one of which has heating and cooling, two map pockets, a pull-out drawer and a 220-volt AC outlet.

The 10.1-inch touchscreen multimedia system is serviceable but feels slightly small for the luxury segment. Graphics aren’t the sharpest, the layout isn’t always intuitive and some functions, like the heated steering wheel, require digging through menus. Wireless Apple CarPlay and Android Auto performed flawlessly throughout the week and the 12.3-inch digital instrument cluster is clear and well laid out.

Boot space is modest for a people mover, offering 280L with all rows in place which is enough for a small grocery run but not for a fully-loaded family outing. Folding the third row expands capacity to 1500L, though that leaves you with a four-seater. The loading height is low, which helps, but it has a tall lip which prevents it from being ideal for sitting on during tailgates or picnics. There’s a small underfloor compartment housing the tyre repair kit and a powered tailgate rounds out the package.

The Ioniq 6 is just under 4.9m long and the wheelbase is close to three metres, so no surprise there’s an impressive amount of space inside the car.

A flat floor enhances the roomy feel, plus controls for windows and mirrors are located in the centre console or on the dash rather than the front doors, which has allowed the armrests to be trimmed down for some extra breathing space.

As mentioned earlier, there’s no gearshift in the centre console, either. It takes the form of a rotary stalk on the right hand side of the steering column. It doesn’t take long to get used to and I found it pretty handy to use.

There are large bins in the doors with space for bottles, two cupholders in the console and a medium-sized lidded storage box (which doubles as a centre armrest) between the seats.

A lengthy tray underneath the main console keeps additional loose items under control and a generous glove box slides out from the dash rather than flipping open. So, there’s plenty of storage on offer.  

Move to the rear and it feels like you’ve teleported into the back of a stretch limo. With the driver’s seat set to my 183cm position there is huge legroom.

Hyundai says thanks to the use of high strength steel the backs of the front ‘relaxation’ seats fitted to the AWD models are appreciably thinner than normal, also increasing rear space.

Rear headroom is fine sitting in a normal, relaxed position, although sitting bolt upright my bonse grazes the headliner. 

Three abreast for adults will be okay for short runs, but not a goer for lengthy road trips. Three up to teenage kids will be fine, though.

Speaking of kids, parents will appreciate ‘Quiet Mode’ which limits audio to ‘25’ in front and mutes the rear. Perfect for uninterrupted sleep back there, or keeping the noise to a minimum for those furiously focused on their favourite game or a movie.

Backseaters are provided with bins in the doors, although the section scooped out for bottles is small, there are two cupholders in the fold-down centre armrest, netted map pockets on the front seat backs and a small slot for keys or a phone under the adjustable air vents at the rear of the front console.

Connectivity and power options run to three USB sockets in the front (one Type-A for media and charging, plus two Type-C for power only), a 12-volt socket under the front console, and two Type-C ports in the back. That’s plenty. 

Boot space is 410 litres (VDA), and the rear backrest split-folds 60/40 to liberate more room. Worth noting there are no tie-down anchors in the boot, but there is an underfloor storage compartment, plus a 45L ‘frunk’ under the bonnet of the RWD and a 14.5L storage space in the front of AWD models.

The boot lid is powered but there’s no spare, just a mobility kit. Grrrr!

If you want to hook up the tinny or camper trailer, towing capacity is 1500kg for a braked trailer and 750kg unbraked.

A bi-directional ‘Integrated Charging Control Unit’ (ICCU) allows for ‘Vehicle to Load’ (V2L) functionality on the inside and the outside of the car. There’s a house power-style three-pin outlet at the base of the rear seats or a simple adapter plugs into the charging outlet. Super-handy for camping, picnics, you name it.

Hyundai is offering the Ioniq 6 in three grades, the RWD Dynamiq at $74,000, before on-road costs, then the AWD Techniq at $83,500 and top-spec Epiq at $88,000.

At those prices you’re going to want a substantial list of included features, and aside from the performance and safety tech we’ll get to shortly, the standard equipment list is long.

The entry-grade Dynamiq features remote start, capacitive touch front door handles, dual-zone climate control, twin 12.3-inch screens covering multimedia and instrumentation, sat nav, a head-up display, Bose eight-speaker audio (with digital radio), Android Auto and Apple CarPlay, leather-appointed seats, leather-appointed steering wheel, alloy pedal covers, 10-way power-adjustable and heated front seats, LED headlights and tail-lights, auto rain-sensing wipers, a power (hands-free) boot lid and 18-inch alloy wheels.

Hyundai’s Bluelink connected car services are on board as is over-the-air software update capability. 

The Techniq adds a glass sunroof, 20-inch alloys shod with Pirelli P Zero rubber, ventilated front ‘relaxation’ seats, a heated steering wheel and heated rear seats.

Then the Epiq tips in digital side mirrors, a battery conditioning system, and high-efficiency (heat pump) heating.

Tesla’s three-grade Model 3 line-up is similar with a RWD entry model. It’s well specified and roughly $10K cheaper, but can’t match the Dynamiq’s driving range. The two more premium Model 3 variants are AWD and close on price to their Ioniq 6 equivalents.

Like the Ioniq 5 this car will be sold via a ‘direct to consumer’ online model, with dealer “delivery partners” charged with getting it into peoples’ hands.

Both M8 grades share the same plug-in hybrid powertrain, pairing a 2.0L, four-cylinder, turbo-petrol engine with a single electric motor. Combined, they produce up to 274kW of power and 630Nm of torque which is impressive on paper, though it only manages 0‑100km/h in 8.8 seconds. Once the battery is depleted, outputs drop to a more modest 140kW/320Nm. Power is sent to the front wheels through a two-speed automatic transmission, and the M8 is not rated for towing.

To get the best performance from this type of set-up will require diligent recharging.

The entry-grade Ioniq 6 is the rear-wheel drive Dynamiq, featuring a 168kW/350Nm permanent magnet synchronous electric motor on the rear axle powered by a liquid cooled lithium-ion battery.

The all-wheel drive Techniq and Epiq models feature an additional permanent magnet motor at the front for a combined output of 239kW and 605Nm.

Drive is fed to the wheels via a single-speed reduction gear auto transmission on the rear or both axles.

The M8 is equipped with a Type 2 CCS charging port, accepting up to 6.6kW on AC and 39kW on fast DC power. Being able to use a DC charger is a definite plus for a plug-in hybrid and you can charge the battery on this type of charger from zero to 80 per cent in around 30 minutes.

Its 25.57kWh lithium-ion battery is generous for a plug-in, delivering an electric-only range of up to 106km (WTLP). With a combined cycle (urban/extra-urban) fuel consumption figure of 6.1L/100km and a 56L fuel tank, the M8 offers an overall driving range of more than 1000km which is excellent for a vehicle of its size. As with any plug-in, regular charging is key to achieving these figures; over my week of driving, I averaged 6.2L/100km, which is very excellent.

GAC recommends a minimum 91 RON unleaded petrol.

All versions of the Ioniq 6 carry the same 77.4kWh lithium-ion Polymer battery and the car’s 800V architecture allows it to use 350kW DC fast charging for a 10-80 per cent fill in 18 min.

The number of genuinely fast chargers available is increasing rapidly and that fill time is impressive.

Drop to 400V (50kW charging) and that time increases to 73 min, while 7.0kW AC charging from 10 to 100 per cent will take close to 12 hours.

The ports behind the not-fuel flap are a Type 2 for AC and CCS Combo2 for higher powered DC charging.

And if all else fails, you’re also equipped with a portable charger/cable so you can access house power for a full charge in, wait for it… 34 hours 20 min.

Quoted WLTP range for the RWD Dynamiq is 614km, that number dropping to 519km for the more powerful, dual-motor Techniq and Epiq models.

The WLTP combined cycle energy consumption figure for the Dynamiq is 14.3kWh/100km, with the Techniq and Epiq models at 16.9kWh/100km.

A ‘Disconnector Actuator System’ (DAS) on the front axle of the AWD grades is able to automatically engage and disengage drive to the front wheels as required, to reduce mechanical drag, lower energy consumption and increase driving range.

On test, in the Dynamiq, over a mix of suburban, b-road and freeway running we saw an average of 16.1kWh/100km which is a pretty good result.

Around town, the M8 delivers plenty of power and is whisper-quiet when running in electric mode. Once the battery depletes or you switch over to the petrol engine, that sense of instant oomph fades. Overtaking on hills is achievable, but even with an empty car it can feel a little underwhelming.

Steering is light, but the car feels solidly planted in most situations. Handling isn’t as dynamic as a Kia Carnival and the M8 can feel a touch ungainly through bends, though it’s more than manageable for everyday driving.

Ride comfort is high, especially for passengers, due to forgiving suspension and a cabin that doesn't let a whole lot of road or wind noise in. The M8 is a comfortable cruiser.

Visibility is surprisingly good for a 5.2m-long vehicle with minimal blind spots from the driver’s seat. The bonnet and dash, however, stretch further than they appear, which can make judging the nose a little tricky at first.

Ground clearance is only 143mm, so it’s easy to scrape the nose over speed bumps or when parking. The 360-degree camera system is decent, but manoeuvring into tight spaces still requires some care as it fills out a space. You also have to leave about a metre of clearance behind you if you want to open the tailgate.

Hyundai claims the RWD Ioniq 6 Dynamiq will accelerate from 0-100km/h in 7.4 seconds, which is not hanging around, and it feels every bit that quick. 

In fact, it has more than enough performance for sharp response in the city and easy cruising on the highway.

Step up to the AWD Techniq or Epiq and you’re hitting 100km/h in just 5.1 seconds, which is properly rapid. 

A single-speed ‘shift-by-wire’ reduction gear auto transmission sits on the rear or both axles and you have the choice of ‘Normal’, ‘Eco’, ‘Sport’ and ‘Custom’ drive modes, which fine-tune power output, accelerator response, steering weight as well as power distribution between the axles on AWD models.

Hyundai’s ‘E-Active Sound Design’ (e-ASD) changes the ‘sound texture’ as you drive with a noise roughly approximating Luke Skywalker’s Landspeeder coming through the speakers.

It’s fun for a while, but I found myself turning it down, then off, for the majority of the launch drive. And in that silent mode you can feel and hear (or not?) the impact of the car’s super-slippery shape. No wind noise and only modest tyre rumble at 110km/h on the freeway. 

The Ioniq 6 sits on Hyundai’s ‘Electric Global Modular Platform’ (E-GMP) which features the flat battery pack mounted low down, skateboard-style, between the axles. 

Suspension is strut front, five-link rear, and although the set-up hasn’t been tuned locally, Hyundai Australia says it’s been involved in the development. 

The front seat remained comfy after hours behind the wheel, but it must be said bumps and thumps from typical highway surfaces made their presence felt on a regular basis.

That’s not unusual for a full electric vehicle, but with the RWD Dynamiq riding on relatively cushy Hankook 225/55 ventus S1 evo3 rubber, it’s surprising.  

In corners you can feel the effect of the car’s low centre of gravity with the battery and motor(s) mounted low in the chassis. It hunkers down and remains beautifully balanced and secure through sweeping bends.

But even though the car points nicely, a meaningful connection between the front tyres and your hands on the steering wheel is MIA. 

The physical brakes are vented discs at the front and solid rotors at the rear, adjustable through ‘Normal’ and ‘Sport’ settings, and they’re nice and progressive.

However, there’s more fun to be had with the regenerative braking, adjustable through three levels (‘Strong’, ‘Medium’, ‘Soft’) via steering wheel-mounted paddle shifters.

Move to the highest setting and you’re in ‘i-Pedal’ mode which means for the majority of the time easing off the accelerator is all that’s required to wash off speed before coming to a reasonably prompt halt.

In terms of ergonomics, the simple dash layout works well thanks to a sensible mix of digital and physical controls, the head-up display is crystal clear, and the big screens for media and instrumentation are hard to fault.

A word of warning, though. An over-speed chime fires four times when you even marginally exceed the detected limit. It quickly becomes intensely annoying, the saviour being an off button in the vehicle settings menu. Downside is it defaults to ‘on’ every time you stop and re-start the car. Ugh!

The Ioniq 6 showcases the latest version of Hyundai’s ‘SmartSense’ active safety suite - Everything from front and rear auto emergency braking (AEB) to a bunch of assists, including lane change, blind spot, rear cross-traffic, and heaps more. No surprise it’s scored a maximum five-star ANCAP rating.

The airbag count runs to seven - dual front for the driver & passenger), front side (covering the thorax and pelvis), full-length side curtains and a front centre/side bag to minimise head clash injuries in a side impact.

There are three top-tether points and two ISOFIX anchors for baby capsules and child seats across the rear row.

The GAC M8 is backed by a seven-year, unlimited-kilometre warranty, along with five years' complimentary roadside assistance, which is competitive against several of its nearest rivals. Service pricing has yet to be confirmed, though servicing is scheduled at 12-month or 15,000km intervals.

For now, the service network is limited, with around 10 centres nationwide, though GAC offers authorised servicing through third-party providers such as MyCar, which helps broaden access in the short term.

Hyundai covers the Ioniq with a five-year, unlimited km warranty, with eight-year, 160,000km protection for the high-voltage battery. Both are industry standard these days.

There’s a lifetime servicing plan with maintenance intervals set at an impressive two years/30,000km. 

At this stage cost is $560 a throw, which is pretty handy when you consider the lengthy service intervals. 

A ‘Premium Roadside Support Plan’ is complimentary for the first 12 months and renewed annually while the vehicle is serviced by Hyundai.

Also complimentary is a ‘Sat Nav Update Plan’ which includes nine updates to be used within 10 years.
