Mazda BT-50 vs MG Cyberster

What's the difference?

The MY25 Mazda BT-50 benefits from its robust Isuzu underpinnings to excel in this dual cab-chassis configuration, particularly with Mazda’s premium heavy-duty aluminium tray as fitted to our test vehicle. Fact is, apart from the big drop in payload required to tow 3500kg (but it’s not alone there) it’s hard to find any major flaws. Overall, it’s an excellent workhorse that would be well suited to a multitude of tradie tasks. 

The Cyberster is certainly an impressive thing in a lot of ways, but if you were expecting a perfect sports car from MG, you'll be a bit disappointed. 

It's quite expensive if you're looking for a nice EV, but on the flip side it's quite cheap if being fast is your main concern.

If anything, the Cyberster is an exciting look at what the brand is capable of, even if it's a bit rough around the edges.

It must be said that Mazda’s stylists did a commendable job with the third-gen BT-50 when it launched in 2020. Five years later it still looks fresh and we’re yet to find anyone who doesn't like its styling, which is in stark contrast to its polarising predecessor.

Its exterior sculpting embodies Mazda’s design language to maintain a strong family resemblance to the popular CX line of SUVs, yet does not detract from the tough and purposeful appearance expected of a 4x4 ute.

The MY25 facelift includes a newly designed front bumper, radiator grille and unique LED headlights. At the rear, pick-up models incorporate what Mazda describes as a ‘mountain-inspired ridged design’ along the bottom edge of the tailgate, along with new LED tail-lights and a larger Mazda logo.

Apart from the mountain-inspired ridged design, also evident on the glove box lid, the latest XTR interior is largely unchanged, blending different shades of grey with satin chrome highlights on the dashboard and door linings, contrasting fabric seat trim, exposed stitching on seams and adjustable centre console air conditioning vents for rear seat passengers.

MG reckons the Cyberster draws on the proportions of classic roadsters like its MG A and B from the ‘50s and ‘60s.

And I reckon that’s about where the comparison ends, really.

But don’t get me wrong, I think it’s got some pretty angles and nice elements.

It’s got the long bonnet, but its cabin isn't set so far back and its aerodynamic lines and curves probably weren't a priority back then either.

This is the standard colour, English White, which is more like off-white or cream or beige.

You can have a red roof on the lighter colours, white, silver, and grey, but red and yellow Cybersters have black ones.

The tail-lights at the back were inspired by the union jack, but they’re probably one of the elements on this car I'd put in the ‘tacky’ column.

Our test vehicle’s 1910kg kerb weight and 3100kg GVM results in a meaty 1190kg payload rating. However, that drops to 891kg after you deduct the combined weight of the premium heavy-duty aluminium tray (243kg), nudge bar (9.0kg) and towing kit (47kg).

It’s also rated to tow up to the class-benchmark 3500kg of braked trailer but with its 6000kg GCM (or how much it can legally carry and tow at the same time), towing that weight would require a substantial 590kg reduction in payload to avoid exceeding the GCM.

Even though few (if any) BT-50 owners would need to tow 3500kg, it’s important to be aware of these numbers if the need arose, to ensure the combined weight of your vehicle and trailer does not exceed the legal limit.

The premium heavy-duty aluminium tray from Mazda’s genuine accessories range is a nice bit of kit with its Mazda-branded tailgate decals and mudguards.

The tray is almost square with internal dimensions of 1800mm length and 1777mm width. And it has numerous internal load-anchorage points, external rope-rails and a sturdy mesh-style rear window protector, plus removable ‘quick-lock’ ladder racks with fold-down load retainers up top.

There’s also a 1500mm-long underbody drawer with adjustable internal dividers and a four-stage incremental locking system. An HDP (High Density Polyethylene) 25-litre water tank complete with tap and handwash bottle-holder resides under the right side of the tray, with a sizeable and lockable HDP toolbox under the left side.

The driver and front passenger have comfortable bucket seats and the rear bench is also accommodating, with ample head and kneeroom even for tall people.

However, shoulder room would be tight for three big tradies, so like most dual cabs short of a full-size US pick-up it’s tolerable for short trips as a five-seater but works best as a four-seater for longer drives.

Cabin storage includes a large-bottle holder and bin in the base of each front door and the dash has upper and lower glove boxes, an overhead glasses holder and a pull-open compartment to the right of the driver’s knee for small items.

The centre console has an open tray at the front, dual small-bottle/cupholders in the centre and a small box at the rear with a contoured lid that doubles as a driver’s elbow rest.

Rear passengers get a large-bottle holder and small bin in each door, plus storage pockets on the front seat backrests and a pair of pop-out cupholders in the fold-down centre armrest.

The 60/40-split rear bench seat’s cushions can also swing up and be stored vertically if more internal load space is needed. This also reveals two underfloor compartments with lids for keeping valuables out of sight.

A three-screen dash sounds a little daunting at first, but it’s not that far from the giant screens in some new cars now.

The central 10.25-inch screen is info only, while the flanking 7.0-inch screens are touchscreens, as is the climate control screen in the console.

As much as I’m a fan of physical buttons where possible, this car shows that multiple screens means you don’t need many sub-menus.

Basically, this feels like a lot, but you get used to it relatively quickly.

And while it also seems like MG’s software has become more intuitive and less laggy, the placements of the screens is a little annoying - the side screens on the dash are blocked by the steering wheel, and the central touchscreen is a bit fiddly.

Like I mentioned, no wireless phone mirroring is a let-down and there’s not really an obvious place to put a phone, but the ability to level out the cup holders is kind of interesting and the central storage where the USB-A and C ports are is big enough.

There’s a narrow bit of storage behind the seats, but the boot is actually 249 litres and seems much more usable than you might expect.

It's also worth noting the Cyberster comes with an AC slow charging cable as standard, but not a DC fast-charging cable for plugging in at some charging stations.

The MG Cyberster finds itself here as the only electric convertible sports car on offer, which means it’s hard to compare its $115,000 price tag to any direct rivals.

The Kia EV6 GT and Hyundai Ioniq 5 N are the wrong shape, the Porsche Cayman has the wrong running gear and most other things with doors like this are a lot more expensive.

So what does $115,000, before on-road costs, get you?

It’s only available in one variant, with pretty much the only cost-option being paint colours.

Aside from the scissor doors, there’s the electric folding roof, triple-screen cockpit with another centre panel, an eight-speaker Bose sound system, heated electric seats and steering wheel, and ambient lighting.

The exterior lights are all automatic intelligent LEDs, and you can open the doors with the key fob.

It is, however, missing a couple of things.

No phone charger might be down to space, but no wireless phone mirroring is a bit annoying, and the manual steering wheel adjustment feels a little cheap in a six-figure EV.

The BT-50’s drivetrain, shared with its D-Max donor, comprises Isuzu’s proven Euro 5-compliant 3.0-litre, four-cylinder, turbo-diesel that produces 140kW of power at 3600rpm and 450Nm of torque between 1600-2600rpm.

This is paired with an Aisin-sourced six-speed torque converter automatic featuring ‘intelligent’ protocols that prompt downshifting to assist with engine-braking on steep descents (great when towing) and overdrive on the top two ratios optimises fuel economy during highway driving.

It also offers the choice of sequential manual-shifting, which can be handy when hauling and/or towing heavy loads particularly in hilly terrain.

The part-time, dual-range 4x4 transmission features 2.482:1 low-range reduction and a switchable locking rear diff

Okay, here’s where the Cyberster gets impressive.

Its dual-motor set-up combines a 150kW front motor and a 250kW rear motor for a total of 375kW.

Peak torque is a hefty 725Nm.

All that is enough to get you and two tonnes of MG from zero to 100km/h in 3.2 seconds.

Sure it tops out at 208km/h, but the rush of hitting highway speeds is already enough to put your licence at risk.

Mazda claims an official combined cycle (urban/extra-urban) average of 8.0L/100km and the dash display was showing 10.2 at the completion of our 369km test, which comprised a mix of city, suburban and highway driving of which about one third was hauling a near-maximum payload.

Our own figure, calculated from fuel bowser and tripmeter readings, was slightly higher again at 10.6L/100km but still within the usual 2.0-3.0L/100km discrepancy between official and real-world figures and not bad for a two-tonne-plus 4x4 ute.

So, based on our figure, you could expect a realistic driving range of around 700km from its 76-litre tank.

The MG Cyberster has a 77kWh battery and a claimed efficiency of 19.1kWh/100km.

While that means its claimed driving range of 443km relies on a bit of energy to be recuperated from braking, something you don’t really get on the highway, it actually works in the car’s favour during dynamic driving.

After 264km of driving on a test loop that included some urban but mostly highway and rural driving, the Cyberster’s trip computer displayed a 19.4kWh/100km average consumption.

The battery sat at 27 per cent, with 108km estimated range remaining.

While 443km of total range seems optimistic for a car that’s likely to be driven relatively quickly a lot of the time, the efficiency of the Cyberster held up better than you might have expected.

The cabin is spacious and, with side-steps plus large handles on the front windscreen pillars, it’s easy to climb aboard and find a comfortable driving position.

All-around vision is good and active driver aids like blind-spot monitoring, rear cross-traffic alert and reversing camera instil confidence, particularly when hauling taller loads that block rear vision through the central mirror.

The engine is responsive in city and suburban use, thanks largely to its broad spread of torque across a 1000rpm-wide band from 1600-2600rpm that showcases its useful flexibility. The six-speed automatic has well-spaced ratios and shift calibrations that feel like they get the best out of this engine, either unladen or when hauling heavy loads.

It feels well-planted on the road and displays sure-footed handling if driven at appropriate speeds for a high-riding 4x4 ute, combined with excellent steering feel and responsive braking.

The unladen ride is firm, as you’d expect given the heavy-duty rear suspension unique to cab-chassis models, but the combined sprung weight of the tray and tow bar ensure it’s not too harsh.

To test its payload rating we strapped 830kg onto the load tray, which with driver and half a tank of diesel was a snip under its GVM limit. Even so, the rear leaf-springs only compressing 40mm under this loading, which left more than 40mm of bump-stop clearance that ensured no bottoming-out on our test route.

It hauled this big load with competence and a smoother ride quality, given the large increase in sprung weight allowed the heavy-duty rear suspension to do what it’s primarily designed to do.

There was also minimal effect on steering and braking response and the engine’s ample torque was not phased by this payload, particularly on our 13 per cent gradient, 2.0km-long set climb at 60km/h.

Engine-braking on the way down was also robust, highlighting the advantage of larger displacement engines (3.0-litres-plus) on overrun when restraining heavy loads on steep descents.

It also has low engine, tyre and wind noise at highway speeds, where the engine requires less than 2000rpm to maintain 110km/h thanks to its overdriven top gear with full torque converter lock-up.

This ensures the BT-50 is a comfortable and economical highway cruiser, with average fuel consumption that quickly drops into single figures on long hauls.

There’s good news and bad news about the Cyberster from behind the wheel.

The good news is it’s quite easy to drive this thing very fast. 

The bad news is it feels like it would be quite easy to get sick of as a day-to-day car, depending on your situation.

The first thing I noticed is the seat feels a bit high, even at its lowest setting. That's likely due to the placement of the battery pack under the floor of of the car.

Following that, if you’re taller than me (I'm five foot 11), it feels like the wrong road surface will have you nudging your head into the roof liner.

That mechanical roof should take about 15 seconds to lower or raise, and that can be done at speeds up to 50km/h.

It could be a symptom of trying to keep 1985kg tied down, but some of Melbourne's highways and arterial roads between 70 and 100km/h had the Cyberster bobbing quite a bit.

But the suspension doesn't let individual bumps intrude too much into the cabin, so it’s not all bad.

Similarly, there’s good and bad when it comes to the steering and braking.

The first being that the steering seems pretty accurate, even though the feedback is a bit numb. 

The braking on the other hand is handled by some pretty capable Brembos up front that pull the heavy roadster up quickly, but don’t always clamp as hard as you might expect when approaching a traffic light at 60km/h.

But stopping’s one thing, and going’s another.

There are three main drive modes, Comfort, Sport, and Super Sport, which mainly alter the acceleration intensity. And they feel well calibrated.

Comfort keeps things calm and cruisy, Sport is plenty for the road, and Super Sport has the potential to draw the attention of the authorities.

There’s good adjustability when it comes to regen braking, and even a decent single-pedal driving mode.

Aside from a couple of particularly heinous roads, the Cyberster held mostly flat when cornering at high speeds, but the potential for its suspension to let its wheels lose their footing might - or should - stop you from pushing the MG too hard.

At high speeds, there’s a bit of wind noise that you really can’t complain about if you’ve just purchased a drop-top, but the noise, vibration and harshness is decent, all things considered.

My only gripe with the interior fit out is that the passenger seat wobbles a little, and rattles on the surface behind it before moving it forward.

It’s impressive what this car can do in terms of performance, it’s just a shame it’s not more playful.

The Cyberster hasn’t been tested by ANCAP but as a niche sports car, it may never get tested.

The good news is it rides on the same platform as the MG4, which has five stars.

It’s got frontal and side airbags, plus all the usual new-car tech like adaptive cruise, lane-keep assist, blind spot warnings, collision warnings and avoidance, and speed limit warnings.

The Cyberster’s active safety is actually mercifully restrained, giving a couple of relatively quiet dings when exceeding the limit before you turn it off, letting you do the steering even when lane-keep is on, and in my case, only giving me a driver attention alert when I yawned while at a red light.

Our test vehicle comes with a five-year/unlimited km warranty.

Scheduled servicing is every 12 months/15,000km whichever occurs first.

Mazda’s ‘estimated service cost’ for the first five years/75,000km totals $2547 which is an average of $509 annually.

MG has a 10-year/250,000km warranty that’s pretty impressive by industry standards, and the warranty also covers its EVs.

It’s important to note that the convertible roof is one of a few items (including 12-volt batteries and light bulbs) that MG covers for less than 10 years. In the case of the roof it’s only five.

It’s worth closely reading the fine print before you crack into buying a car, regardless.

There are also ten capped-price services which occur every 12 months or 25,000km, ranging from $246 to $785. The average price per service is $503.40.

MG also offers free roadside assist for the period of the warranty.
