Gac M8 vs Lexus RX350L

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.

Lexus has seemingly added two extra seats to its RX range without any design or dynamic drawbacks. If you're a fan of the five-seat car, there's little doubt you'll be a fan of this one, too. 

What it will come down to, though, is how often you use the third row of seats, and how big the humans that will be sitting in them in are. If they're for kids or for occasional use, the space will be ample. But if your child has undergone a Tom Hanks in Big-style growth spurt, you will likely find the space back there too tight for everyday use. 

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. 

All the action takes place at the back end here (essentially from the rear wheels back), with Lexus adding 110mm in length to form the RX L, which sits on an identical wheelbase to the five-seat car.

They deserve credit for not making this seven-seat version feel like a behemoth, with the extension in keeping with the style of the five-seat car (same 'floating roof' sitting above a kinked pane of glass), with only the more vertical and extended boot line hinting at the third row inside.

Elsewhere, it’s business as usual for the RX L, with the bigger model sharing the sharply angled body styling, narrow headlights and ferocious-looking grille of the standard RX.

Inside, expect a premium-feel interior, with leather seats in the first and second rows (the third gets the man-made stuff), elegant wood finishing and a sleek and simple dash set-up dominated by a floating screen in its centre.

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.

You know how there are some seven-seat SUVs in which, at a pinch, you can squeeze two adults into the third row? Well, the RX L isn't one of them.

For one, climbing over the second row (after pulling a manual handle that Lexus says is quicker than an electric set-up) requires some acrobatics. And once in the seat, my head (I'm 175cm) found itself in an intimate relationship with the roof. My knees were forced into the seat in front, and most worryingly, my presence pushed the second row far enough forward to make that passenger uncomfortable, too. 

Still, how often are you really going to squeeze adults back there? There is certainly enough room for younger kids, or - as I suspect is more likely - for the third row to be used as an in-case-of-emergency option. It can house a child seat, too.

There's not a bad ambiance back there, though, with artificial leather seats, two central cupholders and tri-zone climate with vents and temperature controls. Middle-row riders now get an extra 45mm of forward adjustability (to compensate for the third row), and there are two cupholders hidden in the pull-down seat divider and bottle room in each of the rear doors.

Up front, expect two cupholders, along with a pocket in each door, while the large central storage bin is home to two USB connection points and a power source, the latter matching a second power source underneath the air-conditioning controls. 

And so, to the boot. All three rows in place, you'll find 176 litres of storage to the seat-tops (211 litres to the roof). Lower the third row, and that number climbs to 433 litres. Drop the second and third row, and you'll find 966 litres of storage.

First, the bad news. There's a price punish for opting for the seven-seat RX. How much, though, depends on which trim level you decide on. 

The RX L arrives in 'Luxury' and 'Sport Luxury' trim levels, and with two engines; a petrol-powered V6 or a hybrid option that adds an electric motor. Luxury prices start from $84,700 (a $3280 increase over the five-seat car), while the Sport Luxury models start from $101,500 (a $1630 rise). 

Opt for a Luxury car ($84,700 for the 350L, $93,440 for the 450hL) and you'll find leather seats in rows one and two, and artificial leather in the third. You'll also get heated and ventilated front seats, a leather-wrapped steering wheel and tri-zone climate control.

Outside, expect proximity unlocking, 20-inch alloys, LED headlamps and DRLs as well as standard roof rails. Technology is handled by a nav-equipped, 8.0-inch display that pairs with 12 speakers. There is no Apple CarPlay or Android Auto, though, and the entire system is operated via the 'Lexus Remote Touch' mouse pad thingy that I can't get used to no matter how hard I try.

Spring for the Sport Luxury ($101,500 for the 350L, $110,240 for the 450hL) and you'll add a colour head-up display and moon roof, as well as adaptive suspension, heated second-row seats, a nicer interior treatment and LED headlights with adaptive high beam. Your screen is bigger (now 12.3 inches), and it now pairs with a 15-speaker Mark Levinson stereo, 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.

There are two engine options on offer here; the V6 of the 350L or the hybrid powertrain of the 450hL.

The six-cylinder petrol engine is good for 216kW at 6300rpm and 358Nm at 4600rpm, sending that power to all four wheels via an eight-speed automatic transmission. 

The hybrid option uses the exact same engine, just with lower outputs of 193kW at 6000rpm and 335Nm at 4600rpm. It's paired with an electric motor that lifts the total output to 230kW. That combination pairs with a CVT auto, sending power to all four wheels. 

Lexus claims identical performance figures for both options, with a 0-100km/h sprint of 8.0 seconds and a top speed of 200km/h.

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.

The petrol V6 will require a claimed 10.6L per 100km on the combined cycle, with the hybrid predictably performing better, returning 6.0L/100km on the same cycle. Emissions of CO2 are pegged at 234g/km (V6) and 137g/km (hybrid).

The V6-powered RX boasts a 72-litre tank, while the hybrid shaves several of those off, offering 65 litres.

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.

Let’s start with the good news: having admittedly only been behind the wheel for a shortish stretch (and a lot of that was on a freeway) I’ll be damned if I can spot the difference from five- to seven-seater.

Its 110mm longer than the five-seat car, of course, and it's heavier, too. And a more thorough test might well reveal those extra kilograms from behind the wheel. But I suspect you'd have to be truly pushing the RX L around some serious corners to have any chance of noticing.

Keep in mind, this isn't the sportiest option in the segment, and this L version isn’t either. The steering feels a little vague and flat on-centre, and neither engine offers face-peeling acceleration. But the ride is terrific, the cabin is comfortable and polished and both the Luxury and Sport Luxury are ferociously well-equipped. 

We'll wait until we get the RX L into the office for a more thorough examination, but after our brief taste test, we reckon there'll be no on-road penalty in opting for the seven-seat option.

Lexus has a strong reputation on this front, and the RX L is predictably well-sorted from a standard safety viewpoint.

Expect 10 airbags (with the curtain bad extended to the third row), a reversing camera, blind-spot monitoring, rear cross-traffic alert and rear parking sensors. 'Lexus Safety Sense+' also arrives as standard, which adds active cruise control, lane-keep assist, auto high beam and an AEB pre-collision safety system the now includes pedestrian detection for the first time. 

The five-seat RX was awarded the maximum five-star ANCAP crash rating when tested in 2015.

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.

Expect a four-year/100,000km warranty (that's 12 months longer than both Germans), and the RX L will require a trip to the service centre every 12 months or 15,000kms. Your first service is free, and total maintenance costs for the first 60,000km will run you $2031.31.
