Renault Symbioz vs BMW M8

What's the difference?

There’s certainly a lot to like about the Renault Symbioz. It may cost more than its direct competition, but it looks, feels and drives with an edge on many of its rivals. And the integration of the Google system will no doubt appeal to some, especially a younger audience which craves the latest tech.

But the extra cost coupled with the image problem French cars have had in Australia - justified or not - will make it a hard sell. The small SUV market is dominated by the big name brands and cut-price models - and the Symbioz is neither. 

Renault Australia has no ambition for this to out-sell the Tiggo 4 Pro and Kona, but even attracting modest sales in such a highly competitive segment will be a hard slog.

If you’re willing to make an unconventional choice, though, you will likely enjoy your time with this little French alternative.

With dramatic looks, a luxurious spec, and impeccable quality, the BMW M8 Competition Gran Coupe remains supremely well controlled as it delivers eye-widening performance and amazing dynamics. But there’s an ‘edge’ to the experience you need to be ready for. If I was determined to head for the Aussie ‘fast lane’ in a BMW 8 Series Gran Coupe I’d opt for the M850i and pocket a lazy $71K (enough for a cheeky M235i Gran Coupe to add to your collection).

The Symbioz effectively replaces the Captur in the local range and brings with it the French firm’s latest design language; which debuted on the recently launched Scenic.

Certainly, compared to some of the more conservative and simple models in the small SUV contest the Renault stands out. It has the look and feel you expect from a European car, on the outside and in the cabin.

One of the reasons for this is Renault Australia is offering seven colours, but only Flame Red is standard rather than the typical white and the other more muted hues cost an additional $900.

In terms of its size and where it fits into Renault’s slightly crowded SUV line-up, the Symbioz is 4412mm long, while the all-electric Scenic E-Tech is 4470mm, the more rugged Duster is 4345mm and the Megane E-Tech is 4200mm. So they’re all quite close, but thanks to unique designs and powertrains (and the fact the Duster isn’t designed to be a Renault), they fit together to form a cohesive line-up for you to choose from.

Want to start a vigorous car enthusiast discussion (more a verbal punch-up)? Simply ask whether a four-door car can be a coupe.

Traditionally, the answer is no, but over time numerous automotive brands have applied that description to cars with more than two doors, including SUVs!

So, here we are. A four-door ‘Gran Coupe’, and the M8 Competition version retains the smoothly tapering turret and frameless side glass that help give selected BMW four-door models the same swoopy, coupe look.

At close to 4.9m long, a fraction over 1.9m wide, and under 1.4m high, the BMW 8 Series Gran Coupe has a firmly planted, low-slung, wide-track stance. Always a subjective call, but I for one, think it looks stunning, especially in our test car’s ‘Frozen Brilliant White’ matt paint finish.

In an era of comically oversized BMW grilles, things are relatively under control here, with a bright black finish applied to that ‘kidney grille’, as well as the huge front bumper air intakes, front splitter, front fender vents, exterior mirrors, window surrounds, 20-inch rims, lip spoiler on the boot, rear valance panel (incorporating a functional diffuser), and quad exhaust tips. The roof’s black, too, but that’s because it’s made of carbon-fibre.

Overall the M8 Competition Gran Coupe is a compelling combination of strong, confident character lines along the bonnet and lower flanks, with tightly wrapped curves following the high hip line, and more organically irregular, yet distinctly BMW shapes in the head- and tail-lights. 

The interior is a beautifully balanced design with a broad centre console sweeping up to the middle of the dash and wrapping around to focus on the driver, in typical BMW fashion.

 The multi-adjustable sports front seats are immaculate, with high-end quilting in the centre section matching a similar treatment in the doors. The dark grey (full) leather trim is offset by carbon and brushed metal trim elements for a cool, calm and focused feel.

Crack the bonnet open and a spectacular ‘BMW M Power’ carbon cover dressing the top of the engine is guaranteed to impress friends and family.

There are two elements that really stand out inside the Symbioz when it comes to practicality and technology, and how they are integrated.

The first element is that Renault has partnered with Google and this new model features the latest Google Automotive Services (GAS) which includes integrated Google Maps as well as access to the Google Play Store for downloading apps, but does so much more. Google Assistant is offered by default but you can also upgrade (via an over-the-air update) to Gemini, the tech giant’s artificial intelligence (AI).

This means with a simple ‘Hey Google’ voice command you can search for not only an address but anything you might need when you’re behind the wheel. So, if you are driving and want to stop for a coffee, you can ask Google Assistant or Gemini to find you a suitable spot to stop.

We were able to sample both systems and there is a clear difference between the two, with Gemini able to provide more detailed answers. But you have the freedom to choose if you want AI in your car or not, and can simply decline to update and stick with Assistant.

The second stand out feature is the amount of physical switchgear used throughout. Despite the switch to Google, Renault has stuck with physical controls for all the key functions - climate control, stereo, etc - which adds to the cost but makes for a much easier and safer driving experience.

While it may be a small SUV in size, Renault’s designers have created a surprisingly spacious and well-considered interior.

Up the front there are plenty of small item storage spaces, with an emphasis on small. But what they lack in size they make up for in quantity. There is a small ledge ahead of the stubby gear selector, with the wireless charging pad hidden underneath it. There are two cupholders and a small lidded console box as well, plus small door pockets.

In terms of space for people, up front the seats are comfortable and roomy, while in the rear the back of the driver and passenger seats have been heavily sculpted out to create a good amount of kneeroom.

As for the boot, Renault claims it is one of the best in the segment thanks to the back seats being on a slider, which allows you to trade-off rear passenger space for more cargo capacity.  It means the mild hybrid has between 563-695L depending on the rear seat position, while the full hybrid is smaller, between 460-592L; with the difference attributed to the different position of the spare tyre.

The fact both models include a temporary spare tyre is notable in itself, as it’s something increasingly rare in this segment and very much a welcome addition in Australian conditions.

Of the M8 Competition Gran Coupe’s 4867mm overall length, 2827 of it sits between the front and rear axles, which is a pretty healthy wheelbase for a car this size (and 200mm more than the 8 Series two-door coupe).

Space up front is generous, and one upside of a four-door, rather than two-door coupe, is you’re not struggling quite so much for space to get in and out when parked next to other cars.

Once inside, there’s plenty of storage up front, with a large lidded box/armrest between the front seats, twin cupholders in the centre console, as well as another covered area for wireless phone charging and extra bits and pieces in front of that. Long door pockets provide space for bottles, and the glove box is a decent size. There’s 12V power as well as USB sockets for media connection, with charging outlets in support.

At first glance you’d swear the rear seat was designed as a two-seater only, but when push (literally) comes to shove a centre passenger can squeeze in, legs straddling the rear console.

In terms of legroom, at 183cm (6’0”) I could sit behind the driver’s seat set for my position with knee room to spare, but headroom is another matter, with my noggin making solid contact with the soft Alcantara headlining. It’s the price you pay for this car’s racy profile.

There’s a neatly trimmed storage box and two cupholders in the fold-down centre armrest, plus door pockets with enough room for small bottles. The rear console houses dual climate controls, twin USB power sockets, and a small oddments tray, as well as buttons for the optional rear seat heating fitted to our test car ($900).

The 440-litre boot is a bit like the car itself - long and wide, but not very high. The rear seat split-folds 40/20/40 if you need more space, and the boot lid is automatic with a hands free function. But don’t bother looking for a spare of any description, a tyre repair kit is your only option.

At $349,900, before on-road costs, the BMW M8 Competition Gran Coupe sits in an interesting part of the upper-luxury, high-performance market, the unifying theme being a forced induction V8 engine under the bonnet. 

On price, it lines up almost exactly with Bentley’s twin-turbo Continental GT V8 ($346,268), but that’s a more conventional, two-door coupe. 

If it’s four doors you’re after, some compelling options, within shouting distance of the M8’s price, include the supercharged V8 Jaguar XJR 575 ($309,380), twin-turbo V8 Maserati Quattroporte GTS GranSport ($299,990), and the presidentially powerful and imposing twin-turbo V8 Mercedes-AMG S 63 L ($392,835).

But, arguably, the competitor that lines up best in terms of intent, performance, and personality is Porsche’s Panamera GTS ($366,700). You guessed it, a twin-turbo V8, also designed to prowl the autobahn’s left lane. 

So, in this exalted company you need to bring your quality and features A-game, and the M8 Competition Gran Coupe doesn’t disappoint. 

Running through all the car’s standard equipment would be a tedious exercise, if only for the sheer volume of features, and hopefully, the following highlights package will give you a feel for the level we’re talking about here.

Aside from copious amounts of active and passive safety tech (covered in the Safety section) this brutal Beamer features, four-zone climate control, configurable ambient (interior) lighting, keyless entry and start, ‘Merino’ leather trim covering the seats, doors, dash, M steering wheel, and gearshift, ‘Anthracite’ Alcantara headlining, 20-inch alloy rims, active cruise control, a digital instrument panel, head-up display, and laser headlights.

The electrically-adjustable sports front seats are ventilated and heated, while the leather-trimmed steering wheel, front centre armrest, and even the front door armrests can also be dialled up to a toasty setting.

You can also add a 10.25-inch multimedia display featuring navigation (with real-time traffic updates), Apple CarPlay and Bluetooth connectivity, as well as gesture control and voice recognition. The exterior mirrors are heated, folding, and auto-dimming. The Bang & Olufsen surround sound audio system boasts 16 speakers and digital radio.   

There’s also a digital dash display, panoramic sunroof, rain-sensing wipers, soft-close doors, power sunblinds on the rear, and rear side windows, and a l-o-t more. Even in this price range, that standard fit-out is impressive.

As mentioned earlier, Renault is offering two powertrains - a mild hybrid and a conventional hybrid. Remarkably, despite this being 2026, this is the first time Renault has ever offered a hybrid powertrain in Australia.

It’s a decent hybrid option too, making a respectable 116kW and 265Nm from its 1.8-litre four-cylinder petrol engine and electric motor.

Meanwhile, the mild hybrid features a 1.3-litre four-cylinder petrol engine and makes a more modest 104kW and 245Nm.

The M8 Competition is powered by an all-alloy, 4.4-litre twin-turbo V8 engine, featuring direct-injection, as well as the latest version of BMW’s ‘Valvetronic’ variable valve timing and ‘Double-VANOS’ variable camshaft control, to produce 460kW (625hp) at 6000rpm, and 750Nm from 1800-5800rpm.

Designated ‘S63’, the engine’s two twin-scroll turbos are located, along with a cross-bank exhaust manifold, in the engine’s (90-degree) ‘hot vee.’ 

The idea is consistent transmission of exhaust energy to the turbos for improved response, with the reversal of usual practice completed by inlet manifolds positioned on the engine’s outer edges.

Drive goes to all four wheels via an eight-speed ‘M Steptronic’ (torque converter) auto transmission with ‘Drivelogic’, and dedicated oil cooling, as well as BMW’s ‘xDrive’ all-wheel drive system.

The xDrive set-up is built around a central transfer case housing an electronically-controlled, variable multi-plate clutch, with front to rear drive distribution set to a default 40:60 split.

The system monitors multiple inputs including, wheel speed (and slip), acceleration and steering angle, and is able to vary the ratio up to 100 per cent rear thanks to the ‘Active M Differential.’ 

Renault Australia management was keen to push the convenience of a traditional hybrid, which requires no outside charging and is therefore easier to use - even if that means it can’t match the efficiency of a plug-in hybrid.

According to the company, the so-called ‘multimodal hybrid gearbox’ is the key to its efficiency. On paper it’s a four-speed automatic, but it’s integrated with the engine, motor, starter and generator, which means the engine and electric motor can both drive the front-wheels, while also helping the Symbioz return a claimed 4.7L/100km.

The battery is quite small at just 1.4kWh battery, but there is an ‘E-Save’ button that allows you to prioritise the petrol engine if you want to hold on the silent power for later.

With a 48-litre fuel tank and the 4.7L return, the Symbioz has a theoretical driving range of more than 1000km on a single fill.

As for the mild hybrid, it gets a more conventional seven-speed dual-clutch transmission and has a claimed fuel economy rating of 6.4L/100km. 

It has the same fuel tank, so its theoretical range is 750km, which is still a good return but obviously not as attention grabbing as the full hybrid.

Claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle is 10.4L/100km, the M8 Competition emitting 239g/km of CO2 in the process.

Despite the standard auto stop/start function, over a week-long combination of city, suburban, and freeway running we recorded a (dash-indicated) average of 15.6L/100km.

Pretty thirsty, but not outrageous when you consider this car’s performance potential, and the fact that (purely for research purposes) we exploited it regularly.

Recommended fuel is 98 RON premium unleaded, and you’ll need 68 litres of it to fill the tank. That equates to a range of 654km in line with the factory claim, and 436km using our real-world number as a guide.

If you’re going to pay a premium for your non-conformist small SUV, one of the perks should be an above-average driving experience and thankfully the Symbioz delivers in this regard.

It’s not that it channels the iconic Renault Sport hot hatches of the past, or even sets a new dynamic benchmark for the class, but amid the sea of more-affordable models the Symbioz feels more composed on the road.

It’s responsive to your inputs as the driver and inspires confidence that not all of its rivals do. A big part of that is likely down to the tyres, with Renault avoiding the trap of cheaper, less impressive rubber that detracts from some of its competitors and instead offer Continental tyres on the Techno and Michelin rubber on the Esprit Alpine.

The ride is firmer than average, which helps with the responsiveness but means you can feel bumps in the road a bit more sharply than some, although it’s never uncomfortable.

It’s worth noting that we did see a trip computer fuel economy figure below the claimed 4.7L/100km, but an extended stretch of our drive was on motorways, which obviously helps keep that number down.

There’s something teutonically symmetrical about the way the M8 Competition Gran Coupe delivers its prodigious thrust.

Peak torque of no less than 750Nm is available from just 1800rpm, remaining on full song across a broad plateau all the way to 5800rpm. Just 200revs later (6000rpm) peak power of 460kW (625hp!) takes over to finish the job, with the rev ceiling sitting just over 7000rpm.

That’s enough to slingshot this 1885kg bruiser from 0-100km/h in 3.2 seconds, which is supercar fast. And the engine and exhaust noise produced by the 4.4-litre twin-turbo V8 during such rapid acceleration is suitably brutal, courtesy of electronically-controlled flaps in the system opening up. 

On a more civilised drive you can reduce the exhaust noise via an ‘M Sound Control’ button on the centre console.

The eight-speed auto is fast and positive, especially in manual mode, which dials up the fun via wheel-mounted paddles. And when it’s time to direct this car’s forward momentum into lateral movement BMW has brought in the engineering heavy artillery.

Despite its frameless door body structure the M8 Competition Gran Coupe feels solid as a rock thanks in no small part to its ‘Carbon Core’ construction, using four primary components - carbon-fibre-reinforced plastic (CFRP), aluminum, high-strength steel, and magnesium.

Then the ‘Adaptive M Suspension Professional’ (with active anti-roll stabilisation), the tricky xDrive continuously variable AWD system, and active M Sport diff combine to keep everything under control.

Suspension is a double wishbone front, five-link rear arrangement, with all key components in alloy to minimise unsprung weight. In concert with the electronic wizardry on-board, it helps keep the M8 buttoned down with only modest body roll in enthusiastic cornering, as the rear-biased AWD system seamlessly distributes drive to the axle and wheels that can make best use of it.

The price you’ll pay for the track-ready tune is in compromised ride comfort. Even in the ‘Comfort’ setting, the M8 Competition is firm, and feels corrugations and imperfections to a surprising degree.

An alignment of the BMW 8 Series planets left me with the keys to this car and the M850i Gran Coupe (also using the Carbon Core body) at the same time, and the difference between their softest settings is appreciable.

Also be aware that at 12.2m the M8 Gran Coupe’s turning circle is substantial, and it’s just as well all that camera, sensor and self-parking tech is available to help you guide this ship into port.

The M8’s electrically-assisted, variable-ratio steering features an ‘M’ specific calibration to deliver satisfying precision and good road feel. But in similar fashion to the ride a noticeable amount of unwelcome feedback comes through to the wheel.

The fat Pirelli P Zero rubber (275/35 fr / 285/35 rr) grips hard, and the monster brakes (ventilated all around, with 395mm rotors and six-piston calipers up front) wash off speed without fuss or fade.

But overall, you’ll have to live with a less refined drive when you sign on for the M8 Competition. Straight away it feels faster but lacks the M850i’s lighter touch. No matter which drive or suspension mode you select, responses are more aggressive and physical.

To fully explore and enjoy the M8 Competition’s abilities it feels like the race circuit is its most appropriate habitat. On the open road, the M850i is all the Gran Coupe you’re going to need.

The BMW M8 Competition Gran Coupe hasn’t been assessed by ANCAP or Euro NCAP, but that doesn’t mean it’s lacking in terms of active and passive safety tech.

As well as expected crash avoidance features like stability and traction controls, this M8 features the ‘Driving Assistant Professional’ suite which incorporates active cruise control (with ‘Stop & Go’ function) and ‘Night Vision’ (with pedestrian recognition).

Also included are AEB (with pedestrian and cyclist detection), ‘Steering and Lane Control Assistant’, ‘Lane Keeping Assistant’ (with active side collision protection”, an ‘Evasion Assistant’, a ‘Crossroads warning’, ‘Wrong-way warning’, as well as front and rear cross traffic alert.

The headlights are ‘Laserlight’ units incorporating ‘BMW Selective Beam’ (with active high-beam control), there’s a tyre pressure indicator, and ‘Dynamic Brake Lights’ to warn those behind of an extreme braking event.

Plus, M8 Competition owners score complimentary enrollment in the BMW Driving Experience Advance 1 and 2 courses.

To help guide your parking efforts there’s a hi-def reversing camera (with panoramic view monitor), rear parking distance control, and ‘Reverse Assist’. But if all else fails the car can park itself anyway (parallel and perpendicular).

If all of that isn’t enough to avoid an impact, you’re protected by 10 airbags (dual front and front side, knee bags for the driver and front seat passenger, as well as side airbags for the second row, and curtain airbags covering both rows).

An automatic emergency call function contacts the BMW call centre for connection to relevant services in the event of a crash. And as has been the case with BMW since the dawn of time, a first-aid kit and warning triangle are on-board. 

The Symbioz is covered by Renault’s standard five-year/unlimited km warranty, which was fine a few years ago but when more affordable models are offering seven years and longer, it feels like a missed opportunity for the French firm.

The company offers ‘Assured Servicing Pricing’ which covers the first five years or 150,000km - whichever comes first. Intervals are every 12 months/30,000km and cost $2715 for the hybrid and $2695 for the mild hybrid.

Renault, which is looked after by an independent distributor in Australia, has 52 dealerships spread across the country.

BMW offers a three year/unlimited km warranty, which is at least a couple of years off the mainstream market pace, and lagging other premium players like Mercedes-Benz and Genesis, both sitting at five years/unlimited km.

Roadside assistance is included for the duration of the warranty period, and the standard ‘Concierge Service’ provides everything from flight information, to global weather updates, and restaurant recommendations, from a real human.

Technically, service is ‘condition based’ with the car telling you when it’s time to hit the workshop, but you can use every 12 months/15,000km as a guide.

BMW Australia offers ‘Service Inclusive’ packages that require customers to pre-pay for servicing, allowing the cost to be covered off in finance or leasing packages and reducing the need for concern about paying for maintenance further down the track.

BMW says there are different packages available, from three to 10 years, or between 40,000 and 200,000km.
