Gac M8 vs McLaren 750S

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.

Not just a love letter to the intoxicating delights of the mighty V8 engine, the McLaren 750S is a genuine joy across the board.

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. 

McLaren concedes the cosmetic updates for the 750S are “relatively subtle”, but there have been some key changes.

The front bumper and splitter are new, as is the rear bumper, while the rear wing is now bigger, with 20 per cent more surface area.

Also at the back, a new (and lighter, of course) stainless steel exhaust is now centre-exit, rather than off to either side.

Like the 720S before it, the 750S looks more like a statement of intent than a designer’s dream, with aerodynamic function over form the order of the day.

In the cabin, you’re looking at two sports seat, a grippy Alcantara steering wheel, and two relatively small screens by today’s sizeable standards.

You can have your cabin trim in full Nappa leather, or the leather mixed with Alcantara, and the audio is taken care of by Bowers & Wilkins.

Still, the 750S delivers everything you need and nothing you don’t in a car in this category.

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.

Next question, please. This is a stripped-back, lightweight, two-seat supercar designed to get you to, and then around, a corner in the least amount of time possible. So, no, you can’t fit much in the way of grocery shopping in the back.

You can, however fit a total 150 litres (front) and 210 litres (rear) in the 750S, and it gets bonus points for having deep cut-outs in the roof that make slipping in under those scissor doors far easier than you might expect.

The McLaren 750S can be yours in hardtop ($585,800) or drop-top Spider ($654,600) guises, both of which have travelled north from the pricing applied to the 720S, which was $489,900 at launch, and its Spider equivalent, which was $556,000.

What you’re getting, though, is more — and less— of everything. More power, more performance, more downforce and more stiffness, combined with less weight, with McLaren having taken a forensic approach to stripping kilos from the 750S.

What you're not getting, though, is much in the way of niceties, with the McLaren 750S offering less interior tech and comforts than a mid-range hatchback (“it now has Apple CarPlay,” they exclaimed excitedly).

But for mine, that only enhances the drive experience, with the 750S offering a genuinely pure-feeling drive — a steering wheel free of buttons, a cabin largely free of distractions, no safety chimes bonging, and a nuclear reactor attached to your right foot. These are all good things.

Elsewhere, the McLaren 750S rides on ultra-lightweight forged alloy wheels (19-inch front / 20-inch rear) wrapped in Pirelli P Zero rubber as standard, and there are thinly cushioned carbon-fibre-shelled racing seats that hold you snuggly in place, and are every bit as comfortable on bumpier roads as cuddling a cactus.

In the cabin, McLaren has worked to up the tech, though its best to remember this is pared-back over plush.

A steering column-mounted driver display is new, and delivers all your key driving info, and it’s framed by all your go-to switches, like your 'Drive Mode' options. 

In the centre, an 8.0-inch portrait-style screen now has Apple CarPlay as standard (but not Android Auto), and there are USB-C and USB-A connections for your devices, too.

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.

Ah, now we’re talking. In the huge-displacement world of supercars, a 4.0-litre twin-turbo V8 might sound a little on the small side when put up against V10s and V12s out of Italy. 

But this mid-mounted, twin-turbo powertrain perfectly compliments the overall balance of the 750S, and when its 552kW and 800Nm (fed through a seven-speed automatic) meets the lightweight McLaren, the results are staggering.

The zero to 100km/h dash is dispatched in 2.8 seconds, while 200km/h flashes by in 7.2 seconds. Want to push to 300km/h? You’ll need just 19.8 seconds.

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.

McLaren says you can expect 12.2L/100km on the combined cycle, with emissions pegged at 276g/km. But you can also expect to win the lottery. It doesn’t make it likely.

It’s hard to imagine how softly you’d have to treat the 750S to get anywhere near those numbers, but I know you almost certainly won’t. The temptation is simply too great.

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.

Usually we wouldn’t be dedicating much space to the kilogram’s shaved here and there off the total weight of a vehicle, but it’s important in this case.

In the 750S, that starts with a bespoke carbon-fibre monocoque platform, which is not only light, but also so inherently stiff that even chopping the roof off for the Spider version required no extra bracing or supports, and only marginally impacts the performance figures.

Then, there are the lightest alloys ever fitted to a series McLaren, which reduce unsprung weight by up to 14 kilos.

That rear wing isn’t just bigger, but also lighter, saving another 1.6 kilos, the carbon-fibre-backed seats save a whopping 17.5kg, the new suspension springs shave another two-or-so kilograms. The list goes on and on.

All up, they've found 30 kilos between 720S and 750S, which is now 1389kg total.

The result is a vehicle that feels endlessly athletic — light, lithe and perfectly balanced — but also one that, when you’re feeding on that endless power, feels as though it might suddenly take flight.

Flat-footed acceleration is laugh-out-loud fun, the tyres scrabbling for grip with each donkey-kick gear shift, even past 100km/h, with the rear end shifting around slightly as the Pirelli rubber deals with the physics of what’s happening. It’s loud, visceral and intoxicating, and you absolutely never tire of it.

But the magic in this McLaren is that it's more than just brutally fast in a straight line, it's also one of the most engaging vehicles I've ever driven, and one that provides a near-telepathic connection to the car, its tyres, and the tarmac below.

The more time you spend behind the wheel, the more tameable it feels, and even at warp speeds (somewhere above 270km/h), you feel connected and in control, owing mostly the open lines of communication between the tyres, the steering and the driver.

Also ferocious is the McLaren's braking force, combining carbon ceramic discs with a rear wing that doubles as a jet-style air brake, and stamping on the brake pedal produces vision-blurring force that leaves you feeling like you're not just stopping, but hurtling backwards through time.

So, race track, tick. But away from it, the McLaren – with its 'Proactive Chassis Control' hydraulic suspension – is surprisingly compliant when you want it to be, with its 'Comfort' drive mode delivering exactly that, softening the important bits so you don’t rattle yourself to death on the freeway.

If the 720S was a benchmark, then this 750S is something else entirely, shifting the needle in every important way to create a vehicle that sparks pure, unadulterated joy from behind the wheel.

Safety systems hardly abound here, and nor is McLaren or ANCAP likely to pony up for the 750S for crash testing.

You do get front and front-side airbags, front and rear parking sensors and a reversion camera, as well as a handy nose-lift function which should stop you scraping over steep speed bumps and the like.

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.

The 750S is covered by a standard three-year, unlimited-kilometre warranty, which is fully transferable.

Owners can also spring for an extended warranty, which can cover the McLaren for up to 15 years.

Servicing is required every 12 months or 15,000km.
