Renault Megane E-Tech vs Mazda CX-70

What's the difference?

The design for the Renault Megane E-Tech is top-notch and the eco-conscious footprint is even better. It’s an easy and comfortable car to be in but the price is a smidge too high in my opinion when you consider there’s currently only one choice for us Aussies and it’s a mid-spec variant at that. It also misses out on some items its rivals have but is a solid EV to consider for urban dwellers.

For mine, the CX-70 is the pick of Mazda's premium SUV range, and if you can survive without a third row of seats, it's significantly cheaper than its CX-90 twin, too.

The E-Tech’s plump body panelling gives me some cute marshmallow vibes from certain angles but there are enough features to keep it looking slick, like the fun LED headlights, massive 20-inch alloys and optional two-tone paintwork.

I’m also a fan of the door handles on the E-Tech as they add some nice focal points, because the front has auto-flush handles that pop out on approach and the back door handles are positioned on the C-pillar.

If you're eco-conscious the E-Tech ticks the box because Renault has designed it to be 90 per cent recyclable.

The body is made of aluminium and can be reformed and shaped into new products at the end of its life. The interior materials are made from recycled fabrics and trims; even the lithium-ion battery is free from any rare earth minerals.

Head inside the cabin and the grey knit trims and upholstery on the seats, doors and dashboard creates a cabin space that feels warm and inviting. It's a similar feel to the Polestar 2 - simple but refined.

Although, with my kid around I have higher anxiety about dirtying them!

Yes, the Mazda premium SUV range can look a little same-same, but Mazda insists there are critical differences.

That said, if you can immediately spot the difference between the CX-70 and CX-90 without taking a peek inside, you're doing better than me, given it is the same exact dimensions as Mazda's three-row flagship.

Sure, Mazda talks about things like this design being a “passion pursuer” that serves up "dignified performance” – all of which sounds utterly ridiculous – but the less marketing-speak version is that it looks like a shapely large SUV that ditches the boxy dimensions of a proper 4WD for a more sleek and swooping profile.

Inside, it's a plush and premium-feeling space, with lovely cabin materials, plenty of tech, and plenty of space.

The E-Tech’s cabin is fairly roomy up front with plenty of head- and legroom. The front seats are super comfortable with powered lumbar support and I wouldn’t mind them not being powered if the price point was a bit lower. 

The rear seat is comfortable enough once you get seated but the top of the door apertures are low, and I have to duck my head to get in and out.

Your head also brushes against the roof lining in the back which isn't terribly comfortable, especially considering there is no fold-down armrest to lean on.

The front row benefits the most with individual storage and you get a lot of options to choose from but the centre console is one of the most practical I’ve seen for the class. Lots of pockets and nooks that feature adjustable 'walls'.

You get a single permanent cupholder but with the removable walls, accommodation for a second cup or bottle, can be catered for.

Underneath the multimedia screen you get a dedicated phone shelf, which I love using.

In the rear, you get two map pockets and shallow bin storage in each door.

The charging options are good with two USB-C ports in each row as well as a 12-volt outlet and a wireless charging pad up front but you miss out on V2L (Vehicle to Load) functionality in this model.

The 9.0-inch touchscreen multimedia system looks great headlining the dash and is easy to access and use. The system rebooted once on me while driving but other than that everything is responsive.

You get wireless Apple CarPlay and Android Auto and the CarPlay is easy to get started.

The steering wheel has numerous stalks, controls, regen paddle shifters and even the gearshifter on the column, too. It takes a beat to get used to it but I like how driver orientated it is.

The boot offers great storage at 440L but it’s a deep well, which might be annoying if you’re unloading heavier gear. There is underfloor storage for the cables, too, and like I said, you miss out on a powered tailgate.

The CX-70 measures a substantial 5120mm long, 1994mm wide, and 1745mm tall, and it rides on a 3120mm wheelbase.

It will tow 2.5 tonnes no matter which engine you choose, and the expansive boot will swallow between 589 litres and 2015 litres, depending on how you configure the backseat.

All of that space translates to a hugely airy backseat experience, with the second row able to be fixed in a position that either prioritises leg room or boot space.

With the former, you've got tons of space in the second row. I'm 175cm, and my knee and leg room was ample, with only the intrusive tunnel that runs down the middle-centre of the cabin eating into leg room for the middle passenger.

There are also air vents and temp controls, twin USB charge ports, seat heating in the window seats and swathes of very nice materials.

The boot is massive, too. I can't even reach the back of the rear seats when I lean into it, and Mazda says it will swallow smaller surfboard or SUPs without needing to resort to roof racks.

Under-floor storage adds a bit more security for precious items, too.

We'll drill down on this a little more in the practicality section, but it's important to note here that the CX-70 is the same size as the CX-90 – both are 5120mm long, 1994mm wide and 1745mm high — which means the only real difference between the two models is the third row of seats in the CX-90.

And, as it turns out, that's a very expensive pair of chairs. The CX-70 starts with the GT trim at $75,970 before on-road costs for the petrol or $77,970 for the diesel, and then climbs to the Azami trim, which is $82,970 or $84,970.

The CX-90, though, is $82,577 or $85,785 for the GT, or $91,461 or $93,030 for the Azami.

That makes the CX-90's third row at least a $6600 option, but as much as an $8000 upgrade. Mazda has made moves to address this, with a drive-away "plate clearance" that closes that gap, but we suspect those offers will become permanent fixtures to make the jump from 70 to 90 less ferocious.

Anyway, Mazda has thrown just about everything they've got at the CX-70. The GT kicks off with plenty of high-end gear, including 21-inch black alloy wheels, adaptive LED headlights, a panoramic sunroof and a handsfree powered tailgate.

Inside, there are twin 12.3-inch screens with Apple CarPlay and Android Auto, a 12-speaker Bose stereo, leather seats that are heated front and rear, three-zone climate control and a heated steering wheel.

The Azami then adds things like ambient lighting, black Nappa leather seats, which are now ventilated in the front, footwell lighting, body-coloured wheel arches and lower cladding and body-coloured door handles.

The Techno EV60 has a single electric motor. It produces a power output of 160kW and 300Nm of torque, and Renault says it will sprint from 0-100km/h in 7.4-seconds.

That's perfectly adequate for keeping up with traffic or getting  around town. You only notice a sluggishness with power when you have a full load of gear. Flipping it to 'Sport' mode make it feel peppier, if you ever need it.

You can have one of two engines in the CX-70, with the cheapest being a 3.3-litre, six-cylinder turbo-petrol, producing 254kW and 500Nm. There's also a 3.3-litre, six-cylinder turbo-diesel, making 187kW and 550Nm. Both are equipped with a 48-volt mild hybrid system to marginally reduce fuel use.

All models are AWD, and pair with an eight-speed automatic transmission.

The official energy consumption figure is 15.6kWh/100km and I averaged 13.9kWh after a fair mix between urban and open-road driving.

That’s outstanding consumption but the official driving range for this E-Tech’s 60kWh lithium-ion battery is up to 454km, which is similar to the Hyundai Kona Electric but I still had an eye on the range during longer trips.

The E-Tech has a Type 2 CCS charging port which means you can benefit from faster DC charging speeds, however, it can only accept a top speed of 7.4kW on AC power.

On a 7.4kW AC charger, you can go from 0-100 per cent in a little over nine hours but on a standard 2.3kW house plug, that jumps up to over 30-hours. 

On a 130kW DC charger expect to go from 15-80 per cent in as little as 30 minutes, which is pretty convenient if you have access to one.

Sadly, the E-Tech doesn’t have vehicle-to-load capability, so you can’t power or charge bigger items.

Petrol-powered cars will sip 8.1L/100km on the combined cycle, while the diesel drops that to 5.4 litres.

Both models get a 74-litre tank, meaning a theoretical driving range of around 900kms in the petrol, and almost 1400kms in the diesel.

I have mostly loved driving the E-Tech. It's easy to cruise around in and the power is adequate for open-road driving but it prefers an urban environment.

The power can feel a bit lacklustre when you are carrying lots of people or gear but you mostly feel that when you're on a steep incline and trying to keep up your speed.

The steering is crisp and that makes the E-Tech very responsive to drive. The power is delivered smoothly and it feels well-balanced when you put your foot down.

There is more roll in corners than I was expecting but the car still feels firmly planted. 

The ride comfort is great. The suspension is more firm than soft which means you feel the road but it's not a major bother. There is a bit of wind noise at higher speeds, as if the door isn’t properly sealed by a millimetre but it doesn't annoy me. 

The regenerative braking is controlled by paddles on the steering wheel and you have three levels plus a one-pedal function to choose from.

The single pedal set-up is pretty smooth, even in stop/start traffic, but it’s great to be able to quickly change modes on the go.

The smaller size of the E-Tech makes it an easy car to manoeuvre in a small car park. You get front, rear and side parking sensors which is great because the reversing camera isn’t as clear as it should be for this price level. 

Interestingly, the CX-70 has been tagged as the expected smallest seller of Mazda's premium SUV range, but I reckon it just might be the pick of the bunch.

Every one of the CX-0 models (60, 70, 80 and 90) all get slightly different suspension tunes, and while you can find harsh edges in the other models, the CX-70 feels utterly composed and refined, at least on the smooth-ish roads of our launch test route.

Perhaps most surprising, though, is the CX-70's ability to hold its own on a properly twisting road. We expected lots of weight transfer and the high-pitched sounds of tyres screaming out in pain, but instead found Mazda's massive SUV served up grip, composure, and very little in the way of sea-swell-style body roll.

The two big six-cylinder engines also feel perfectly suited to a vehicle in this space. There's tons of power whenever you need it, and solid levels of refinement in terms of engine noise or diesel rattles.

For mine, the petrol engine is the pick though, feeing just a little smoother than the diesel option. The latter can feel a bit jerky at slower speeds, whether that's the power delivery or the gearbox, and it doesn't seem to happen with the petrol engine.

The biggest caveat, though, is that we haven't driven the CX-70 in its natural environment, the city and suburbs, so while it largely shone on flowing country roads, how it performs on roads like the ones near your place remains a bit of a mystery.

The CX-70 hasn’t been ANCAP tested, but it does arrive with a pretty stacked safety offering, including a 360-degree-view camera, blind-spot monitoring, front and rear cross-traffic alert, and a total of eight airbags, including a knee airbag for the driver.

The E-Tech comes with a five-year/100,000km warranty, but it’s usual to see an unlimited km term for the class. The battery is covered by an eight-year or up to 160,000km warranty term.

Service intervals are reasonable at every 12 months or 30,000km and you also get five-years roadside assistance included.

Pricing over the first five years ranges from a low of $230.04 to a high of $519.62, averaging out at pretty competitive $317.72 per service. No capped-price deal is available.

Servicing is not particularly cheap in the CX-70, and the service intervals, at least in the diesel, feel a little short, too.

Buy that one, and you’ll be visiting the dealership every 12 months or 10,000kms, and the first five years of ownership will cost you $3298.

Petrol cars require servicing every 12 months or 15,000kms, and five years will set you back $3436.

The CX-70 is also covered by Mazda's five-year, unlimited-kilometre warranty.
