MG Cyberster vs BMW M5

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.

Let’s get one thing out of the way: the new M5 is a very good car. Considering the emissions limitations and size increase of its base model, it is an impressive bit of engineering. 

What’s trickier is deciding whether the new car is really better to drive. Less edgy but supremely comfortable and quiet; BMW leaned into the daily usability of the plug-in hybrid M5 rather than amping the petrol-electric system for maximum thrills. And do you know what? That’s fine with me. 

The new M5 still performs on road and track and does an incredible job of hiding its weight (most of the time). Perhaps the G90 is a little more Audi RS6 than F90 in its demeanour but some would argue that’s no bad thing. 

The concept of the BMW M5 is not static, it evolves with the times, and the G90 is no exception. Expect future Competition and CS variants to unlock some extra lunacy. 

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

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 M5’s raw size is what you notice first. The G90 M5 is a whopping 113mm longer, 67mm wider and 37mm taller than the car it replaces, with the wheelbase stretched 24mm.

It is also the most pumped M5 yet, compared to a 520i it is 70mm chubbier at its flared wheel arches. The ‘M5’ insignia on the C-pillar means you’ll know this is the fast one. 

Presence is not in question, then, but beauty? Not the right word. The G90 makes its predecessors — especially the original ‘E28’ — look demure. 

The cabin layout builds on the concept debuted by the iX electric SUV, with twin integrated screens and focus on technology and minimal buttons. Materials are mostly high quality and feel fitting for the M5’s asking price.

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.

BMW has persevered with its twin-screen, minimal-button approach for its 'Operating System 8.5' in the M5. 

The 14.9-inch central touchscreen is bright, responsive and high resolution but the software remains a little strange. The main interface is classy but when looking for settings to adjust you’re presented with a Windows 95-esque panel of small square touch targets. It’s not intuitive. 

Wirelessly mirroring Apple CarPlay or Android Auto works a treat, at least. Digital climate controls keep temp adjustment persistently on screen and a shortcut to fan speed. The nipple-like vent direction adjustment grows on you, as do the digital vent sliders. 

The 12.3-inch digital driver’s display still doesn’t have the freedom of customisation and clarity of Audi’s interface. 

The M5 has two cupholders, a deep central storage cubby, door bins that swallow two 600mL plastic bottles and twin wireless charging pad that resolutely grips smartphones even under the sort of tummy-churning G-Forces this M5 can manage. 

Setting the M5 apart from the regular sedan is a unique centre console bunching 'M Drive' modes, 'M Hybrid' modes and other shortcut functions together next to the gear toggle and M-engraved crystal 'iDrive' controller.

Comfortable front seats are power adjustable with in/out, up/down lumbar support and have two memory positions. 

The 5096mm long M5’s back seat is very spacious. Headroom is good for those beyond 182cm (six-foot), the bench is extremely supportive, while leg and toe room are adequate.

A fold-down centre armrest has two cupholders and there are USB-C charge ports in the back of each bucket seat for a total of four. 

You can buy an accessory mount that holds tablets or smartphones for rear seat passenger entertainment, too.

When you look in the boot, BMW offering a Touring version of the latest M5 makes even more sense. The load aperture is big but the usable space is narrow; the sides intrude on load space. 

The 466-litre space will make fitting suitcases for an airport run tricky and, even with the 40/60 split-fold rear bench, you will struggle to fit a bike in the back. There’s no spare tyre, either.

The last M5 was well equipped but the new car is wanting for nothing. Australian cars have just about every option for $259,900, before on-road costs.

Australian M5s wear staggered 20-inch front and 21-inch rear alloy wheels paired with standard metallic paint, 'M Carbon Exterior' package (including carbon roof and rear lip spoiler), adaptive LED headlights and BMW’s 'Iconic Glow' illuminated kidney grille surrounds. 

Keyless entry, a heated steering wheel, heated and ventilated front seats, interior camera, powerful 18-speaker Bowers & Wilkins sound system, M seatbelts, four-zone climate control and a power tailgate are the cabin highlights. 

Optional extras are thin on the ground; you can choose from (eight) no-cost paint colours and all manner of 'Individual' shades (from $4100), four interior trims including classy 'Dark Oak' wood and four leather colours. There’s classic black ‘Merino’ leather, or you can have it dyed with a mix of 'Silverstone', red or 'Kyalami Orange'. 

Aside from that, the only major option is carbon ceramic brakes at a staggering $18,500, and an M5 Touring wagon costs $263,900. 

Though the M5 is more expensive than Audi’s closest rival, the RS6, the gulf isn’t huge considering you get a lot more punch in the BMW. Mercedes-AMG does not have an E-Class answer, yet.

Good value, then? Well, an equally potent Porsche Panamera is twice the price. So yes, in a sense.

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.

Unlike the Mercedes-AMG C63, BMW has kept the M5’s eight-cylinder heart and this has proven to be a good decision. 

The 4.4-litre twin-turbo petrol engine has been optimised with “a cross-bank exhaust manifold and optimised oil separation”, says BMW.

The V8 spins to 7200rpm though it isn't a screamer, outputting a full-bodied 430kW (5600-6500rpm) and 750Nm (1800-5400rpm).

Augmented with a transmission-mounted 145kW electric motor that can produce up to 450Nm, thanks to pre-gearing, maximum combined outputs are 535kW and 1000Nm. 

Weight blunts punch, though, so despite nearly 100kW and 250Nm more, the new M5 is a tenth slower to 100km/h than its predecessor (claimed), at 3.5 seconds for the sprint.

You can thank a 220kW/tonne power-to-weight ratio, worse than the old car's 233kW/tonne figure. The new G90 claws some time back with brute force, hitting 200km/h in just 10.9 seconds and goes on to a limited top speed of 305km/h.

You can choose from five powertrain settings, starting with 'Electric' and 'Hybrid' for everyday use, while 'eControl' lets you store battery power for urban use.

'Dynamic' provides the best balance, says BMW, while 'Dynamic Plus' is like a qualifying mode. Think maximum combined punch for up to 10 minutes, at which point you’ll have drained the battery. 

Driving in pure electric mode, the take-off can be a little jerky but the quietude and decent power make it pleasant. Power sources are combined expertly in Hybrid and giving it some stick in Dynamic is more than enough to make your passengers feel queasy.

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.

Electric-only range is rated up to 69km in WLTP testing, but the 18.6kWh battery is more likely to give you around 60km in real-world driving. It can be topped up in about two hours using an 11kW AC charger, or overnight on a three-pin socket. 

BMW includes both Mode 3 (public) and Mode 2 (home) charging cables with the M5. 

The M5 uses 3.2L/100km of 98 RON premium unleaded in ADR testing, corresponding to just 72g/km of CO2, so it should sail through the first rounds of Australian emissions regulations. 

Indulging in what the V8 has to offer sees that consumption spike, though. An enthusiastic road drive saw the M5 gulp 12.4L/100km, according to the trip computer.

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 three M5 elements start with daily usability. We trundled out of Bathurst in electric mode, with the adaptive dampers (and other myriad settings) in Comfort. 

The M5 has steel springs, double wishbone front suspension and a five-link rear axle, all of which has been heavily reworked by the boffins at M. Naturally, the ride is firm, though in Comfort the body moves through its motions smoothly. 

The M5 is an effortless tourer, its eight-speed automatic shmoozing through ratios as it climbs and descends steep gradients. Wind and tyre noise insulation is good on coarse chip tarmac, though a bit more burble from the V8 would be appreciated. 

The M5 has nine adjustable parameters to wake it up: 'Drivetrain', 'Energy Recovery', 'Drivelogic' (gear shift aggression), 'Chassis', 'Steering', 'Brake', 'M xDrive', stability control settings and 'M Sound'. Favourite settings can be stored to the wheel-mounted M1 and M2 buttons. 

With the dampers still in Comfort the M5 remains fantastically capable with power delivery from the xDrive mighty rewarding on corner exit. Sport dampers sharpen the experience up further, amplifying the M5’s surprising agility. Thank the rear-wheel steer for this big sedan’s switchback performance. 

Step beyond the limit of grip, brake too late, or get on the power too early, though, and the M5’s mass reveals itself rapidly. It doesn’t help that the accurate steering is devoid of feel. The brake-by-wire pedal is too numb and light, as well, making it tricky to judge grip levels on the road.

Feel is less of an issue on a dry Mount Panorama circuit, where the M5 turns out to be a total pussycat. The all-wheel drive, consistent dynamics, strong brakes and well-tuned stability control make for an approachable but seriously fast sedan.

The responsive transmission will hold gears to redline and is eager on the downshift in its most aggressive setting while tactile shift paddles make commanding ratio changes yourself that bit more engaging. 

Prodigious punch out of corners is matched by the impressive consistency of the carbon ceramic brakes. The M5 pulled up for The Chase every time with minimal fuss, even from above 250km/h.

Similar credit goes to the 285mm front and 295mm rear Hankook S1 Evo tyres which remained consistent and predictable all day despite reaching temperatures over 130 degrees, according to the tyre pressure monitor.

The regular BMW 5 Series range scored a maximum five stars in 2023 ANCAP safety testing but this does not apply to the M5.

The M5 features nine airbags and a host of active safety systems, including auto emergency braking (AEB), blind-spot monitoring, rear cross-traffic alert, lane-keep assist, auto parking and speed limit assist. 

Lane-keep can easily be turned off via two taps but the other systems require more menu navigation, though are mostly unintrusive. A 'Track' mode disables lane-keep, AEB and other systems along with switching the central display off. 

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.

In Australia, BMW has moved to match other manufacturers in offering a five-year/unlimited kilometre warranty on all its cars. 

Servicing is recommended on a condition basis, with the M5’s multimedia system prompting a visit to the mechanics. BMW offers pre-paid service packs for five years/80,000km at a price of $5059 for the basic offer and $8152 for 'Inclusive Plus', which covers brake pad and rotor replacements. 

It is expensive next to a regular 5 Series but when you consider the purchase price and performance level, the M5’s service pricing is not astronomical.
