Renault Scenic E-Tech vs BMW Z4

What's the difference?

The Renault Scenic E-Tech is lining up against some heavy-hitting competitors, but Renault Australia admits it has one top of mind - the Kia EV5. The Kia’s a quality package and if you’re in the market for a mid-size electric SUV, you’ll no doubt have it on your shopping list. And you should have a look at this slightly smaller car, as well. It has the refinement, practicality and safety to stand up confidently in a rapidly expanding segment.

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.

There are some design tips of the hat to Scenics past in this latest electric version, including blacked-out door pillars and a recognisably angular C-pillar treatment.

But despite the fact it debuted at the Munich IAA Motor Show in late 2023, from its slimline headlights and jagged grille to its sculpted flanks and saw tooth rear end, this fifth-generation Scenic looks contemporary from every angle.

A highlight is the large Renault diamond logo sitting at the centre of a faux upper grille, surrounded by a multitude of the same elongated hexagon shape as a cool recurring graphic, the pattern merging neatly into the headlights.

Speaking of which, the LED beams can be set to produce an elaborate welcome sequence as you approach the car.

The interior feels slick and screen-rich but not at the expense of user-friendly physical controls for audio, ventilation and other commonly used functions.

Recycled fabric on the dashboard and headliner looks and feels good while doing its bit to suppress cabin noise.

Speaking of which, the Scenic is Renault’s poster child for the use of recycled materials in its construction and end of life recyclability.

Everything from ferrous components consisting of 37 per cent recycled materials to a bonnet and doors made of up to 80 per cent recycled aluminium.

The dashboard cowling is made from kenaf, a plant fibre similar to jute; the steering wheel cover is 51 per cent bio-sourced; the cockpit uses 26 per cent recycled plastic; the storage bins in the door panels are 45 per cent recycled fibre, the floor mats are 54 per cent recycled plastic bottles and the seat upholstery is 100 per cent recycled fabric. The list goes on and on, but you get the idea.

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.

In terms of how it all works in practice, at just under 4.5m long, close to 1.9m wide and less than 1.6m tall with a 2785mm wheelbase, the Scenic is more compact than the larger BYD Sealion 7 or Zeekr 7X, for example.

But there’s plenty of breathing room up front, with the centre screen angled towards the driver enhancing the cockpit feel for the one doing the steering.

There are large carpeted bins in the doors with room for bottles and a lidded storage box between the seats doubles as a centre armrest. That lid slides forward by 70mm to cover a small storage cubby under the front of it, which is a handy trick.

Locating the gear selector on the right-hand side of the steering column liberates extra space for a centre cupholder and large console storage bin. There’s a generous glove box and a wireless smartphone charger under the centre screen includes a rubberised base and two lugs to stop devices sliding around. Power and connectivity runs to two USB-C ports and a 12-volt socket.

Moving to the second row, sitting behind my 183cm driving position, while toe room is a little tight (with the driver’s seat set low down), there’s heaps of leg and headroom as well as enough shoulder room (and foot room thanks to a flat floor) for three adults on short to mid-length trips. A pair of adjustable centre air vents is also a welcome inclusion.  

Storage includes door bins (again with room for bottles), large and device-sized pockets on the front seat backs and the pièce de résistance is the evocatively named ‘Ingenious armrest’, which includes a storage area and two cupholders at the base of articulated horizontal arms that allow passengers to mount a phone or tablet at various angles in rubberised slots for joint or solo viewing.

It is, indeed, ingenious and four USB-C plugs (two in the armrest, two near the air vents) mean back-seaters won’t be short of power options.

Boot volume with the rear seats upright is useful at close to 545 litres (VDA), expanding to around 1670L with the 40/20/40 split-fold second row lowered. A power tailgate is standard across the range.

There are bag hooks, tie-down anchors, lighting and a 12-volt socket back there, although for V2L (vehicle to load) functionality you’ll need an accessory adapter to plug into the charge port.

Maximum braked trailer towing capacity is a handy 1100kg, but there’s no spare tyre, only a repair/inflator kit, which isn’t good enough.

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.

Like its Megane E-Tech sibling, the Scenic E-Tech uses an excited synchronous motor which Renault says is more efficient than the more commonly used permanent magnet type, with the bonus that it uses no rare earth materials.

The entry-level Scenic E-Tech Techno's fitted with a 60kWh NMC battery. Its electric motor transfers 125kW and 280Nm to the front wheels and Renault claims a 0-100km/h time of 8.6 seconds.

The Techno Long Range and top-spec Esprit Alpine pack an 87kWh battery and a more powerful motor, raising outputs to 160kW/300Nm and lowering the 0-100kmh sprint time to 7.9 seconds.

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.

Official energy consumption numbers for the combined (urban/extra-urban) cycle are close between the two powertrains at 16.3kWh/100km for the Techno and 16.8kWh/100km for the Techno Long Range and Esprit Alpine, which are bang on average for the class.

Range for the standard Techno is 430km, which is at the lower end of expectations for a medium electric SUV but adding the bigger battery pushes that number out to 625km, which is much healthier and useful day-to-day.

On the launch drive program, which took in some urban but mostly rural B-road running, we saw an average consumption figure of 17.1kWh/100km in the Esprit Alpine, which is pretty good in those conditions.

The car’s 400V electrical architecture allows for DC charging at up to 130kW for the entry model and 150kW for the bigger-battery variants.

At that speed, claimed 15-80 per cent charge times are 32 and 37 minutes, respectively. Not the best, not the worst. AC charge capability is 11kW on all models and a Mode 3 charging cable is included.

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.

Renault says the entry-grade Scenic Techno will accelerate from 0-100km/h in 8.6 seconds with the more powerful Techno Long Range and Esprit Alpine lowering that number to 7.9sec. So, it’s quick without being scary fast.

It’s certainly nippy in traffic and at the risk of stating the bleeding obvious, quiet. Even in the context of premium EVs the Scenic is quiet and refined.

Suspension is strut front, multi-link rear and the car feels super planted. The launch drive took in some reasonably rapid twisting corners and there’s no hint of lateral movement in the car. Body roll is minimal, too.

Tyres are energy-efficient Michelin e.Primacy (Techno - 205/55x19 / Esprit Alpine - 235/45x20) and the steering is quick with a relatively low number of turns lock-to-lock. It’s never jerky or too sharp. Rather, it means the car starts to turn into a corner the instant you apply steering lock.

That said, the feel between your hands on the wheel and the front tyres on the road is less than intimate.

There are four drive modes - ‘Comfort, ‘Eco’, ‘Sport’ and ‘Custom’. None of them adjust the suspension tune, it’s more about accelerator response and we found Comfort delivers the best blend of right-foot urgency and overall composure.

Most of the braking you’re going to do will be courtesy of the regenerative system and there are five levels, adjustable via steering wheel paddles, including the most aggressive single-pedal mode.

The one-pedal setting pulls the car up nice and progressively and if you do need to use the physical brakes, they’re ventilated discs all around. Some bite on initial application, but even on downhill corner sections, leaning on them quite hard, they perform well without drama.

Under the heading of miscellaneous observations, you can sense the ADAS (Advanced Driver Assistance Systems) including functions like lane-keeping assist doing their thing occasionally, but it’s all quite subtle, which is a good thing.

The Esprit Alpine’s sports front seats remained grippy and comfortable after a couple of hours behind the wheel. And it’s worth noting the Scenic’s relatively compact 10.9-metre turning circle helps in slow-speed manoeuvring.

Speaking of which, some of the modes in the audio system and external warning sounds for pedestrian safety have been designed by French composer and performer Jean-Michel Jarre, noted for his electronic, ambient-style music. Hats off to Renault for commissioning him.

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. 

Warranty is five years/100,000km, which is well off the market pace with many competitors at seven, eight and up to 10 years conditional. The battery warranty at eight-year/160,000km matches the market.

Roadside assistance is included for five years, service is recommended every 12 months/30,000km and fixed price servicing is available at a reasonably sharp average of $325 per workshop visit for the first five years.

Renault has 52 dealers across the country covering major cities and key rural areas.

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.
