MG Cyberster vs BMW Z4

What's the difference?

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.

The Z4 didn’t make me feel like Peirce Brosnan’s 007. It’s way too serious – a proper gritty reboot. Maybe it’s meant for Daniel Craig. Either way, its brave design makes it one of the best-looking BMWs of recent memory, and it’s a tech- and comfort-fest that the Bavarian automaker should be proud of. I just wish it was a smidge more fun behind the wheel.

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.

The Z4 is a sight to behold. It’s brave, especially for a BMW, it even betrays the brand’s strongest styling pillars, making its own way with its more horizontal grille design, flat body and curved out rear.

It’s more than that, though. In black, this car looks sinister, brooding. The more you look at it, the more you notice tiny details - the scooped-out sides, or the way the entire rear seems to flick up into the integrated spoiler. I couldn’t get enough of staring at it – it manages to look even better with the roof down.

That’s probably when it hit me. To my eyes, at least, this is the most stunning BMW in years. Sure, the X7 is a sight to behold due to its sheer dimensions and borderline offensive grille, but the Z4 is the opposite. It’s subtle, it hides its details away in its silhouette.

It’s designer, Calvin Luk (an Australian no less), was inspired at least in part by the Z8 – another Brosnan bond car – and you can see the Fisker design reflected in the Z4’s low, flat grille and almost bulbous rear.

Inside, sadly, the Z4’s strong design doesn’t quite play out. There’s no wily Fisker touches here, just a standard set of BMW switchgear. While it all works well, it just dumbs down the Z4’s character.

The big, chunky steering wheel in particular is a let-down. It’s the same wheel that sits in the brand’s X5 SUV, and it feels right there, but not here in a convertible where you’re so close to the ground. A smaller wheel would not only suit this car better, it would make it feel just a smidge more alive. I miss the three-spoke M sport wheel from previous-generation BMW cars.

I do like the dash, which is seemly carved from rhomboid shapes - a theme that rolls into the doors, screens, and vents elegantly. I’m normally not a fan of gloss plastics and chrome touches, but in the Z4 they’re all tastefully applied.

The seats, too, are lovely. I’m not sure about the contrast bright-red leather our car came with, but they’re nice and close to the ground and have excellent trim that you seem to sink into just enough to be comfortable and sporty all at once.

It’s a slick place to be, I just wish it felt less like you were at the helm of an SUV and more like you were driving something that looks this damn good.

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 Z4 is a convertible, so it’s naturally compromised on space. As far as convertibles go though, you’ll be hard pressed to find one you can fit more stuff into.

The Z4 is wide - the same width, in fact, as a 5 Series - and this carries into the cabin. There are only two seats, but those seats are wide, and occupants will find themselves with luxurious amounts of airspace for their arms, as well as excellent leather-trimmed and padded surfaces for landing elbows on.

Legroom is also great, as the seats have a surprising amount of rail-travel on them, so that even taller folk won’t struggle to fit their limbs in.

A genuinely impressive characteristic of the Z4 is much head room there it is. Despite its low-slung looks from the outside, the roof towers over my 182cm tall head when I’m inside, so this isn’t one of those convertibles that feels like braking too hard might simply decapitate those above six-foot tall.

In terms of storage areas you get some long but shallow trenches in the doors, a bay with connection ports and a Qi wireless charging pad under the air-conditioning controls, a glovebox (hey, not all convertibles have them) and a trick centre console that houses two deep cupholders inside.

There’s also a netted shelf behind the seats that could fit small bags, and given the length of the cabin, you could even fit laptops and the like behind the seats provided you haven’t used the full extent of the seat’s rearward movement.

The boot is deep, wide and long for a drop-top, and offers a total of 281-litres which is more than some popular hatchbacks. It even offers tie-down points and netting either side. To top it off, the fabric roof folds away into its own compartment, so the boot space is unaffected if you choose to drop the lid.

For a convertible – the Z4 is a practicality wizard.

The Z4 isn’t cheap, but it plays in a field of expensive Deutsche drop-tops. Our car was the mid-spec 30i which comes in at an MSRP of $104,900 (before on-road costs).

For that you’ll get a more highly tuned version of the base 20i’s four-cylinder turbocharged engine, producing 190kW/400Nm, 19-inch alloy wheels, M Sport brakes, Adaptive M suspension, and adaptive LED headlights.

That’s on top of the already impressively-specified 20i’s kit which includes dual 10.25-inch screens – one for the multimedia functions, the other as a digital dashboard, a head-up display, full Vernasca leather interior trim, auto-dimming rearview mirror, power adjustable and heated front seats with memory function, dual-zone climate control, 10-speaker 205W stereo, a Qi wireless charging pad, and adaptive cruise control as part of a marginally upgraded safety package (more on that in the safety section).

It’s a pretty plush set of equipment, although a challenging value proposition as the almost-as-well-equipped 20i starts from $84,900, a full $20k cheaper.

Rivals for this 30i model? You’ve got the soon-to-be-discontinued Mercedes-Benz SLC300 ($102,500), all-wheel drive Audi TT S quattro ($105,661), and, at a stretch, the entry-level Porsche Boxster ($122,960).

Of course, being a premium European car, there is an extensive options list. Our car was fitted with the excellent and probably-worth-the-money M Sport differential ($2400), as well as the rudely priced M seat belts (literally just the M pattern embroidered in - $560!) and interior ambient lighting package (lovely, perhaps not worth $550).

The Z4 is only offered in five colours, three of which – including our car’s Black Sapphire – come at a cost of $2000. The red interior, surprisingly, is a no-cost option.

If you’re keeping track that brings the car you’re looking at here to $110,410. Not cheap, and it doesn’t have six-cylinders - but given its other attributes explored later in this review, the fact that it still manages to undercut an entry-level Boxster is actually reasonable.

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.

Welcome to the age of ridiculously powered four-cylinder turbo engines. Despite a capacity of just 2.0-litres, the engine in the Z4 30i produces a whopping 190kW/400Nm.

That’s probably enough for a car this size. I’m keen to drive the six-cylinder, but surprisingly it seems to offer diminishing returns for extra cylinders offering a 60kW/100Nm power boost for an extra $20,000. Perhaps a six-cylinder is the way to go in a BMW, and given this car’s other seriously sporty attributes, it might be the only way to make it a bit more… fun. More on that in the driving section.

All Z4s are rear-wheel drive, using an eight-speed torque converter automatic. Sorry, no option for a manual this time around.

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.

It’s claimed that the Z4 will drink just 6.5 litres per 100 kilometres on the official combined cycle test, but I found that sticking my foot in occasionally resulted in a slightly more realistic sounding figure of 8.4L/100km.

That’s still a great fuel consumption number for a car like this, and perhaps one of the strongest benefits of having just four cylinders.

A discerning vehicle, the Z4 will drink nothing less than the best-quality 98RON unleaded to fill its 52-litre tank.

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.

A car that looks this good better live up to the promise behind the wheel, right?

For the most part, the 30i does, but it’s a victim of its own performance credentials and luxuriousness.

See, a drop-top should be fun-packed, you should feel close to the road, connected. Sadly, a combination Z4’s excellent suspension and not-so-excellent SUV-like interior separates you too much from the surface below.

An advantage, of course, is the refinement on offer. The Z4 is easily one of the quietest, most refined convertibles I’ve ever driven, but it’s a little too insulated.

I can’t help but feel like it’s all business and no pleasure. It feels a little more like I should be cruising to work on the autobahn and a little less like I should be flinging it around corners on a tight B-road.

It feels almost wrong to drive it in a T-shirt. It’s serious and doesn’t want you to mess around, it wants you to wear a suit and tie.

This grand-tourer style feel is one that will keep a lot of buyers in the premium space happy, but I’m of the opinion that BMW will have that segment well and truly covered by the new 8 Series. If the budget allows.

Regardless, the 30i’s four-cyl engine feels like any six-cylinder would have a few years ago. It’s got a surge to it in the straights that’s quite satisfying, and it responds via the exhaust with an angry tone that makes it feel a little more alive, especially with the roof down.

This feeling was all helped along by our car’s M active differential which simply won’t let the fat tyres at the rear slide unless you’ve got high-speeds and loads of tarmac to play with – for better or worse.

The Z4 also has ‘variable sport steering’ which reacts to the car’s speed and position of the wheels to adjust the input ratio. It’s good when you’re at speed, but the weight and response of the steering can make the Z4 feel bigger than it actually is at lower speeds. 

The suspension is firm, and can be a little bouncy over rough surfaces, but seems well suited to the Z4’s chassis.

Other than those notable characteristics you’ll find that the Z4 is wonderfully tuned in terms of its inputs, everything is slick and smooth, suited perfectly for long meandering drives.

Convertibles and safety don’t often fall in the same sentence, unless its one where a concerned relative is trying to convince you not to buy one.

In any case, the Z4 benefits from four airbags (dual front and dual side), as well as the expected electronic stability controls. That optional M Sport differential will have the added bonus of preventing any unexpected slip and slide at the rear.

On the active side the Z4 gets ‘Driving Assistant’ which includes forward collision warning (FCW), lane departure warning (LDW), rear cross traffic alert (RCTA), and rear collision warning. The 30i grade also gets 'active cruise control with stop & go' which allows for full auto emergency braking (AEB) with pedestrian and cyclist detection. Not on the spec sheet, but apparently present in the car I drove was some form of traffic sign recognition (TSR) and lane keep assist (LKAS).

A nice high-res reversing camera displayed on the massive touchscreen is a welcome standard addition.

Considering the meagre safety specification of most convertible cars, the Z4 30i shines with a half-way decent active safety suite. But you can forget ISOFIX child-seat anchor points. There aren't any. 

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.

If recent quotes are anything to go by BMW is set to stick by its lacklustre three-year unlimited kilometre warranty, as it says its customers simply aren’t interested in five years (or longer) when it comes to warranty coverage.

It’s a shame, as even Volkswagen has upped its warranty to five years, and Mercedes has considered a 10-year coverage plan in the past.

In terms of servicing, there are two fixed-price plans available – the suspiciously cheap ‘Basic’ plan which comes at a cost of $1373 for five years (or $274.60 per year) and the more realistic-sounding ‘Plus’ which costs $3934 over five years (or $786.80 per year).

Like every other BMW, the Z4’s computer tells you when its service time: how often it needs maintenance will depend on how often – and how hard – you drive it.
