Mercedes-Benz GLB vs MG Cyberster

What's the difference?

The Mercedes-Benz GLB is an oddball. While it isn’t my definition of beauty, it's a surprisingly capable and spacious small-to-medium SUV.

The entry-level GLB200, while comfortable, feels a bit underdone in the engine department. Therefore the mid-spec GLB250 with the more-powerful 2.0-litre turbo and mild-hybrid assistance plus all-wheel drive grip is the better pick.

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.

This isn’t the prettiest car ever. It has the Mazda CX-8 or CX-80 effect where you can tell a smaller car has been stretched and extended to create more interior space. It just looks a little awkward as a result.

The rear section of the GLB in particular is much higher and boxier than the GLA which makes it look rather back-heavy. Thankfully roof rails are standard which toughens the look somewhat.

The facelift that was introduced in 2023 brought an updated front bumper, as well as tweaked LED headlight and tail-light signatures. The changes aren’t wildly different from the original car that launched in 2019 but it’s still fresh enough.

Inside is where this car is starting to look its age. While Mercedes-Benz was one of the first to introduce a wraparound screen set-up combining the digital instrument cluster and touchscreen multimedia system into a single unit, many have copied this and it no longer looks unique.

It doesn’t help that the dual 10.25-inch screens are small now in comparison to newer rivals. It’s standard for a digital instrument cluster to be closer to 12.3-inches in diameter now.

A main interior change with this facelift included the removal of the touchpad controller on the centre console. In its place is now a shallow storage area which doesn’t really serve a purpose.

There’s also a new AMG-style steering wheel as standard which has fiddly gloss black touch sliders that get grimy upon use.

While the changes are welcome, the ageing roots are still present. You can’t escape the blingy touches that just end up looking cheap and tacky.

A key example of this are the air vents which have obnoxious interior ambient lighting in them to try and make the cabin look cool.

I’m also not a huge fan of the star pattern trim on the dashboard and the swathes of stainless steel-looking inlays.

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.

Up front the driver’s seat is comfortable, offering electric adjustability and lumbar support, extendable thigh support and heating. Some extra bolstering on the seat base would be nice though as it’s a little flat for my liking.

While the glossy piano black touch sliders on the steering wheel aren’t the most intuitive, I love holding this leather-wrapped wheel as it straddles the line of being thick enough but not too thick. BMW should take note…

The thin stalks behind the steering wheel are a joy to use and have a nice thwack to them. I appreciate the column-mounted gear selector as this frees up more space on the centre console, though it could be utilised better. More on this in a bit.

The digital instrument cluster offers a range of different themes to select from, though the standard version looks the nicest and offers the most customisation. It’s nice being able to put a full-width map display on the instrument cluster.

The touchscreen multimedia system offers a clean and intuitive interface that’s hard to get lost in. For the most part, however, I ended up using smartphone mirroring. Thankfully this update brought wireless Apple CarPlay and Android Auto.

It’s nice having the row of physical climate control switchgear within easy reach especially as carmakers are now integrating these into the touchscreen interface. Even Mercedes-Benz is guilty of this in its newer cars.

There isn’t a tonne of general storage on the centre console beyond the deep central box which has a split-opening lid. The wireless charger barely fits my iPhone 15 Pro Max, the cupholders are on the small side and the aforementioned storage section where the touch slider once was is useless from a storage standpoint.

Moving to the second row, it’s rather spacious for a small-ish SUV. At a leggy 182cm tall, I have plenty of leg and headroom behind my own driving position.

You’re able to slide and recline each individual seat in the second row to prioritise second-row comfort or allow more space for third-row passengers. It’s needed because third-row space is tight!

Second-row amenities include air vents mounted on the back of the centre console, various storage spaces, two USB-C ports, as well as a fold-down armrest with cupholders. Also if you stare at the back of the centre console it looks very much like a screaming face.

As already mentioned, the third row isn’t the most spacious ever, although this is a small-ish SUV so best not to expect palatial levels of room. It’s likely more for occasional use by children and it’s good to note there is airbag coverage back there.

Amenities are few and far between in the third row, limited to just a few storage spots and a USB-C port on both sides. Unfortunately there are no air vents.

At the back there’s a handsfree power tailgate which is handy if you’ve got your hands full. It opens swiftly, though with all three rows of seating upright there isn’t much room at all. Mercedes-Benz doesn’t even quote a boot capacity figure, but it’s only enough for a bag or two.

Thankfully if you’re not using the third row the benefit of this car is there’s much more boot space than the GLA. Mercedes-Benz claims there’s a generous 565L of boot space, which can further expand to 1800L with the second row folded.

Unfortunately there is no spare wheel in the GLB200 as it has run-flat tyres as standard, though regular tyres with a tyre repair kit is a no-cost option.

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 Mercedes-Benz GLB200 is powered by a 1.3-litre turbocharged four-cylinder petrol engine which produces 120kW and 270Nm.

This engine also features in ‘200’ versions of the A-Class, CLA and GLA, plus versions of it also feature in the Renault Arkana, Captur, Duster, and Kangoo, as well as the Nissan Qashqai and now the new Mitsubishi ASX.

It’s mated to a seven-speed dual-clutch automatic transmission with drive sent to the front wheels only.

Unlike the more powerful GLB250 and AMG GLB35 all-wheel drive trims, the GLB200 is the only model to go without 48V mild-hybrid assistance in Australia. It was originally promised when this facelifted model was announced in 2023.

Mercedes-Benz claims the GLB200 can do the 0-100km/h sprint in 9.3 seconds and top speed is 207km/h.

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.

Mercedes-Benz claims the GLB200 has a combined fuel consumption of 7.5L/100km.

During our urban and metropolitan-based testing, however, we saw an average of 9.0L/100km according to the trip computer which isn’t great but also not the worst I’ve seen. Expect this figure to balloon out further if you load more people onboard as the engine will have to work harder.

There is a 52L fuel tank which requires a minimum of 95 RON premium unleaded petrol.

Using my as-tested fuel consumption figure, this means the GLB200 has a theoretical range of up to 578km.

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.

While this 1.3-litre turbo engine may be sufficient in the smaller A-Class and GLA, it barely scrapes by in the GLB200.

Even with one person onboard the engine has to rev out the first few gears to around 3000rpm to keep up with traffic from the lights. It doesn't have the nicest engine note either.

It doesn’t help that the dual-clutch automatic can be a little vague from a standstill, taking a beat to kick into action. This is most noticeable when doing low-speed manoeuvres or reversing.

Although initial acceleration can be on the thrashy side, rolling acceleration while at speed is a lot more linear and calm thanks to peak torque coming on tap from 2000rpm. This means the car will only downshift when it needs to.

There are a few different drive modes you can select from, but the default ‘Comfort’ mode feels the most natural. ‘Eco’ does quell some of the rev flares during initial acceleration, though the engine feels much more tardy in general.

Linked with these drive modes are the adaptive dampers. This is a very comfortable car, especially on the standard smaller 19-inch alloy wheels as there’s plenty of tyre sidewall to absorb bigger bumps.

Coupled with this is sporty steering that’s direct and makes the car feel nimble despite its 1.7-tonne kerb weight.

It really is the best of both worlds because you get the fun and sporty characteristics from the steering, plus the comfort and supple feeling from the suspension. It’s hard to fault this set-up.

In terms of noise, vibration and harshness (NVH), if you look beyond the sometimes shouty engine, this car is quiet and refined. There’s some tyre roar at higher speeds, but many European vehicles have this trait.

It’s also a benefit that this car is a little older as there aren’t many safety system-related bings and bongs that distract from the cabin ambience.

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.

The GLB200 is covered by a five-year, unlimited-kilometre warranty, like the rest of the Mercedes-Benz line-up.

Logbook servicing is every 12 months or 25,000km, whichever comes first, which is good if you do a lot of driving.

You can purchase a three-, four- or five-year service package which costs $3495, $4650 and $6185, respectively. With the latter this equals $1237 per service, which is expensive, although it is cheaper than the slightly larger GLC.

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.
