GWM Cannon Alpha vs Mazda MX-5

What's the difference?

The Cannon Alpha Ultra PHEV combines five-star safety, a confident warranty, lavish luxury and short-haul electric driving for a competitive price. However, from a pure workhorse perspective, its class-benchmark 3500kg tow rating is offset by a modest payload limit, plus an awkward spare tyre location which could be a deal-breaker for some tradies as it compromises working floor space and the securing of loads.

Ultimately, the design and tech changes to the ND MX-5 will be the biggest day-to-day advantages of the updated model, because the mechanical changes don’t make themselves hugely obvious on the road.

If you’re into track days, it’s still a satisfying car to hustle as fast as you can, but it’s at its most accessible on winding roads for weekend drives, where the new differential and track DSC mode won’t come into play as much.

But in a world where accessible sports cars are becoming a rarity, there’s only one rear-drive convertible with a sticker price appropriate for financial mortals, and it’s a pretty damn good thing that it’s the ND MX-5.

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

Our test vehicle shares the same body-on-frame chassis design, twin A-arm/coil-spring front suspension, four-wheel disc brakes and electric power-assisted steering as the model it replaces, but the previous leaf-spring live rear axle has been replaced by a multi-link coil-spring arrangement. External chrome has also been greatly reduced.

Its luxurious leather-accented interior has a spacious and classy feel with a panoramic sunroof and opulent mix of surface finishes, but some tradies might consider such indulgences too fancy for carting muddy-booted crews.

The PHEV’s larger rechargeable battery pack uses up all the underfloor space behind the rear axle usually occupied by a full-size spare tyre. As a result, the steel-rimmed spare has been moved to a conspicuous location in the load tub, which not only looks like an afterthought but is far from ideal for workhorse duties (see Practicality).

Alright, we’ve all seen ND MX-5s, you don’t need me to tell you about its proportions or explain its design elements to you in too much detail, so I’ll give you the headline changes.

At the front and rear are new pairs of LED head- and tail-lights, respectively… obviously, fitting into the spaces the old ones took up.

The DRLS and reverse lights have come off the bumpers for both, and are now part of the main lights at each end - no more DRLs in the front bumper, and the reverse lights have been replaced by reflectors.

There are new 17-inch wheel designs for the base and GT trim levels, too, and there’s a new colour - Aero Grey.

Inside, it’s a shame that the tan Nappa leather interior of the RF Black Roof can’t be had in a manual roadster, because it’s gorgeous, even though the inside still looks refined enough for a simple sports car in its base cloth trim.

Our test vehicle’s substantial 2810kg kerb weight is 235kg heavier than its hefty Alpha Hybrid predecessor, due largely to the bigger battery and electric motor. That makes it about half a tonne heavier than numerous conventional turbo-diesel 4x4 dual cab utes.

This substantial kerb weight contributes to a sizeable 3495kg GVM, yet results in a 685kg payload rating which is modest compared to some turbo-diesel rivals with genuine one-tonne capabilities.

It’s also rated to tow up to the class-benchmark 3500kg of braked trailer, but with its 6745kg GCM (or how much it can legally carry and tow at the same time) that would require a 250kg reduction in payload (from 685kg to 435kg) to avoid exceeding the GCM.

While it’s unlikely owners would need to tow at the 3500kg maximum, it’s important to be aware of these numbers if the need arises, as that 435kg of payload could easily be used up by a crew of tradies before you could load any of their tools.

The vertical mounting of the spare wheel in the load tub not only reduces floor space and load volume but also restricts the securing of loads, given there’s no anchorage point accessible in the right rear corner of the tub.

So, all load straps extending rearwards must share the same left-side anchorage point, which is far from the ideal even spread provided by four-corner load restraint. This spare wheel location needs a rethink (perhaps a swing-away carrier favoured by 4x4 wagon owners would be better).

We also noted the big button on the two-way tailgate, which enables it to split into a pair of hinged doors, stopped working during our test. Fortunately, it could still open the tailgate as a conventional single unit.

There’s ample interior space, not only for front seat occupants but also those in the back. That includes tall people, given I’m 186cm and have at least 40mm of knee room when sitting behind the driver’s seat when set in my position.

There’s also about 80mm of rear headroom, despite the presence of a full-length sunroof which can often compromise this dimension. However, shoulder-room is tight for three adults, so two would be preferable for long trips.

Front-of-cabin storage includes a large-bottle holder and bin in each front door, plus a large glove box, overhead glasses holder and a pull-out compartment for the driver in the lower dash.

The centre console offers wireless phone-charging and a lidded box (with internal air-con flow available) and two small-bottle/cupholders. Another storage nook in the lower right-side of the console offers two USB ports, a 12-volt socket and enough space for a phone.

Rear passengers get a large-bottle holder and bin in each door, pockets on the rear of both front seat backrests and small pull-out drawers under each outer seat. The rear of the centre console also offers adjustable air-vents, a pair of USB ports plus controls for seat heating/cooling and the sliding rear window.

The fold-down centre armrest offers another wireless phone-charging pad, pop-out twin cupholders and a hidden compartment for storage of phones or other slimline items.

One thing Mazda has significantly changed for the ND is the multimedia screen, now a larger 8.8-inch touchscreen running Mazda’s updated software.

It brings the MX-5 up to date without sacrificing simplicity and makes it a little easier to use. The physical dial and buttons for controlling the screen also remain. The USB-C ports are also new.

Oh, and the MX-5 is the first Mazda model to get Connected Services, which is coming to other Mazda models eventually.

Connected Services allows owners to find, lock, and get alerts for their cars from a phone app, even letting them set curfews to notify them if the car is started during certain hours.

Aside from that, another small tweak is the simplified instrument cluster, which aims to be easier to read even when the roof is open and the sun is bright.

The cabin isn’t built to be plush, it’s built for ‘Jinba Ittai’, Mazda’s philosophy that applies most strongly to the MX-5 which means ‘horse and rider as one’.

And trust me, you feel one with the horse- er, car, when there’s not ample room to move. It’s not restrictive, but it’s cosy. 

Everything’s quite well-placed and it’s not busy with buttons or features in here though, it’s made for focusing on driving. 

One downside is the lack of storage, not even a glovebox, in front of the passenger, and the central storage spot under where your elbow sits is tiny, good for keeping the key fob snug though. Also, the cupholders are able to be removed or swapped between the space behind your elbow, or above the passenger footwell.

There’s also a small storage space between the seats behind where your elbow would sit, though it’s tricky to access while you’re driving.

Then there’s the boot, which is usable for a small amount of luggage at 130 litres in the Roadster and 127L in the RF hardtop.

Finally, as a huge positive, probably the biggest advantage of the ND over any other convertible is how easy it is to open and close the roof in the Roadster. You can do it single-handed, which is great if it starts raining and you’re at a traffic light or able to quickly pull over.

The RF hard-top has a switch that automatically opens and closes the roof section.

Getting into an MX-5 is now a little more expensive, with the base manual Roadster up by $2310 to now start from $41,520 before on-roads.

The top-spec soft-top GT RS is now $51,640, or $2800 more than before.

Pricing for the RF hard top is also similarly bumped up, a base manual costing $46,250, and the most expensive GT RS at $56,140.

There’s also a Black Roof edition which comes with tan Nappa leather inside, but that’s only available in an automatic RF, which is possibly the biggest downside to the 2024 range.

Base models get cloth seats, while GT and GT RS models get heated leather seats. The GT RS also comes with stiffer Bilstein dampers, Brembo front brakes, a bracing strut between the front suspension towers and a DSC-Track mode. The difference there is noticeable, so it's worth the extra spend for the more keen driver.

The higher overall costs bring updated tech, a new 8.8-inch touchscreen and a new limited slip-diff in manual versions, plus tweaked mechanicals like improved acceleration response and lower steering rack friction.

But they do look a tiny bit different too.

The Alpha PHEV drivetrain consists of a 2.0-litre, four-cylinder, turbo-petrol engine that produces 180kW of power and 380Nm of torque. This is paired with an electric motor that adds another 120kW/400Nm, so combined they officially produce 300kW and 750Nm.

The electric motor draws its energy from a 37.1kWh lithium-ion rechargeable battery. GWM claims it can be charged from 30 to 80 per cent in less than 30 minutes using 50kW DC charging, or around 6.5 hours using AC charging.

It also has up to 6.0kW of V2L (Vehicle to Load) functionality, using a dedicated adapter cable which plugs into the vehicle’s charging port and provides a standard three-pin AC outlet for numerous electric tools and appliances.

The nine-speed torque converter automatic, which offers sequential manual-shifting using steering wheel-mounted paddles, is paired with the familiar Borg Warner ‘Torque on Demand’ 4x4 system.

For road use, this has three selectable drive modes ('Standard'/'Sport'/'Eco') with the centre differential remaining unlocked to automatically adjust torque delivery between the front and rear wheels in response to any loss of traction.

For off-road use, selecting '4H' (4x4 High Range) or '4L' (4x4 Low Range) locks the centre differential to provide an even 50:50 torque split between the front and rear wheels. 4L traction can be optimised by engaging the front and rear diff-locks.

Up front, you get one option: a 2.0-litre naturally aspirated four-pot. It makes 135kW and 205Nm, and it’s a delightful little thing, driving the rear wheels only - as it should.

It used to be that the smaller 1.5-litre engine was the more revvy, keen option, rest its soul, but Mazda updated the 2.0-litre to be more eager (and deliver more power) at high revs and basically made the little 1.5-litre redundant.

Anyway, you can have it with a six-speed manual in any variant, or a six-speed automatic in GT guise if you find manual gearboxes difficult or a hassle.

GWM claims official combined average consumption of only 1.7L/100km when the highly-charged battery allows most driving to be done in pure electric mode. GWM also claims an official ‘low charge’ figure of 7.9L/100km, when the battery is depleted and the petrol engine is doing most of the work.

It has an NEDC electric-only driving range of up to 115km and a ‘hybrid’ driving range (petrol engine and electric motor combined) of up to 1060km. The petrol engine drinks standard 91 RON unleaded.

The dash display was showing average petrol consumption of 6.4L/100km at the completion of our 324km test, which comprised a mix of suburban, city and highway driving of which about one third was hauling a heavy payload. This was lineball with our own figure of 6.2 based on fuel bowser and tripmeter readings.

Starting with 90 per cent battery charge, we completed 72km of electric-only driving before it automatically switched to hybrid mode when the charge reached 14 per cent. The system would not allow charge to drop lower than that for the remainder of our test, which was conducted in hybrid mode.

So, based on our own test figures, GWM’s claim of more than 1000km of hybrid driving range is credible from its combined 37.1kWh battery and 75-litre fuel tank capacities.

Mazda says the MX-5 uses 6.8L/100km as a manual Roadster, or 7.0L/100km with an automatic gearbox. Or, in the heavier RF 6.9L for a manual and 7.2L for auto.

Not great for a tiny car like this, but pretty good for a sports car!

It’s got a 45-litre fuel tank, takes premium 95 RON or higher, and while it should hypothetically be able to travel more than 600km with its on-paper claims, expect fuel use to sit closer to 8.0L/100km if you’re driving it anything like it deserves.

It has good steering feel with sophisticated ride quality, the latter thanks to four-coil suspension and substantial sprung weight which helps iron out the bumps and deliver a ride that’s more SUV than ute.

Flatten the accelerator from a standing start and up to 750Nm of torque responds with impressive force, even though you can feel that every one of those Newton metres is required to overcome more than 2.8 tonnes of inertia to get this jigger moving swiftly.

Although the option of sequential manual-shifting is available using the steering wheel paddles, we spent most of the test in auto mode as it felt like it was getting the best out of this complex drivetrain.

It’s a competent highway cruiser, too, with the petrol engine requiring 2200rpm to maintain 110km/h with low noise levels.

To test its GVM rating we forklifted just over half a tonne (505kg) into the load tub, which with driver equalled a 600kg payload that was less than 90kg under its limit. The rear coil springs compressed about 50mm, but there was no evidence of bottoming-out on our test route.

Ride, handling and braking were largely unaffected, along with the drivetrain which made light work of our 13 per cent gradient, 2.0km set climb at 60km/h.

Engine-braking on the way down, in a manually-selected second gear, was equally impressive. It never exceeded the 60km/h speed limit, even though its total vehicle weight of around 3.5 tonnes was being restrained by only a 2.0-litre four and regenerative braking.

It feels like every motoring journo under the sun (literally if the roof is off) owns or has owned an MX-5 of some sort.

And the first time you drive one, you might understand why. 

If you spend your days testing and driving a bunch of different cars that aim to be many things at once, it’s refreshing to drive something that aims to be one: fun.

That’s it, the MX-5 feels like it was built to be fun. Not for convenience, not for power, certainly not for the school run.

And fortunately its simplicity remains with this update. All Mazda has done to change the way it drives is attempt to improve the rear limited-slip differential and improve the steering a little by reducing friction in the rack, as well as improve throttle response.

Has any of that changed the way it feels to drive on-road? No, not massively, but the ND was already such a delight that Mazda could have kept this update to purely design and interior tech changes and it would have still been one of the best-value buys around in terms of fun.

The MX-5 still feels relatively softly sprung while still being a dynamic and communicative sports car that’s engaging to drive even at low speeds, and rewarding (or frustrating) to drive fast.

On tight, winding roads, the MX-5 is at home, its soft suspension keeps you humble with its shifting weight and its relatively meagre outputs keep your licence safe.

In fact, despite being slightly compromised as a daily drive, the MX-5 is still plenty of fun even in traffic, there’s something about the satisfying click as the shifter slips into gear, or the little rev matches heading back down through the cogs when approaching a red light.

The 2.0-litre four-pot is a keen unit, and the six-speed manual is light and easy to work with, plus its steering is light without sacrificing road surface feedback - that feedback can quickly turn into cabin noise on a coarse highway which could become a little irritating on a long trip.

But the MX-5 can still be plenty of fun on track, where you’re more likely to get the most out of its new limited-slip differential and Track DSC mode.

It’s equally frustrating and satisfying to hustle the MX-5 around the East Circuit at The Bend in South Australia, where the track is twisty, busy, and unforgiving. Get it wrong, and the MX-5 lurches or slides to let you know you’ve made an error. 

Get it right, however, and the little roadster glides through the corners, camber changes and even over apex kerbs smoothly and carrying impressive speed.

Plus, the electronic assistance won’t usually kick-in until you really need it, a welcome change from cars that are constantly trying to keep you from having fun behind the wheel.

The ND MX-5 actually scored five stars with ANCAP back in 2016, even though its score has now expired. It’s not obvious how well it would fare under newer, stricter tests, given the small car’s lack of advanced driver assistance - not that that’s a bad thing in the case of a sports car.

Still, for a two-seat convertible, the MX-5 has a decent list of kit to keep you safe including front and side airbags, alerts for driver attention, blind spots, lane departure and rear-cross traffic, parking sensors and a reversing camera, belt pretensioners and side-impact door beams and even automatic Smart City Brake Support.

Warranty cover is seven years/unlimited km with an eight years/unlimited km traction battery warranty and seven years of roadside assist.
