BYD Sealion 8 vs Renault ZOE

What's the difference?

There’s no denying the value the BYD Sealion 8 Premium offers as it packs a lot in for the price. Its efficiency and inoffensive looks add up to a good package and reflect what it does well. That said, the underwhelming driving experience and clunky media system are noticeable. Whether they're deal breakers is up to you.

The Renault Zoe is a fun to drive, ultra-efficient, practical little hatch. But the dollar-shaped elephant in the room is its price. Without the government ZEV subsidies offered in other markets, it's wickedly expensive, and with fresh competition in the shape of a new 'normalised' Nissan Leaf coming soon it'll have to work hard to wean more than a handful of small-car buyers off their fossil-fuel addiction.

The Sealion 8 is a big unit, and its design leans more towards soft and rounded than sharp. There’s a sense of restraint with its pillowy panels, smooth curves and flush door handles all contributing to a clean, almost clinical look.

The 21-inch wheels add a bit of presence, as does the full-width LED light bar with its braided design. But overall, it doesn’t try too hard to stand out. It’s inoffensive - clean and easy on the eye, but it stops short of having any sense of identity.

Inside, the cabin carries that same restrained approach. There’s black leather upholstery, some interesting geometric detailing through the panels and speaker grilles and a generous use of soft-touch materials throughout.

The large displays and panoramic sunroof help lift the space, giving it a premium feel, but more importantly, it’s just a comfortable, easy place to spend time. Which, for a family SUV, arguably matters more than anything else.

Renault claims no less than 60 patents came out of the Zoe's development, but while BMW's i3 is as hip as Kendrick Lamar on his third encore, and even Toyota's long-serving Prius hybrid still looks ready to roll onto the set of the next Avengers movie, this little hatch isn't shouty at all.

It seamlessly merges into the automotive landscape. A cute, small car with a few flashy blue bits in its head and tail-lights giving the only clue to its distinctly unusual internals.

Underpinned by the same platform as the Clio (with an identical wheelbase) the Zoe is slightly longer (+21mm), fractionally thinner (-2mm) and quite a bit taller (+114mm) than its conventionally powered sibling.

Lead exterior designer  Jean Sémériva has literally left his mark on the car, with a full-size thumb print applied in low-relief to the rear door handles. Nice touch.

And monsieur Sémériva has shown admirable restraint in a cool design combining soft curves around the nose, front guards and rear end, with sharp character lines top and tailing the car's flanks.

Vaguely diamond-shaped tail-lights mix a clear lens cover with those nifty blue highlights and brilliant LEDs for an arresting brake and indicator display.

Open the door and a similar blend of tech and tradition creates a clean and simple interior, with strategically placed bright-metal finishes highlighting key elements.

A broad TFT digital instrument screen sits under a minimalist hood, with the 7.0-inch 'R-Link' multimedia screen dominating a central stack lifted by a shiny black face and an illuminated blue keyline around the heating and ventilation controls.

A printed circuit pictogram on the front headrests and left-hand side of the dash is a creative reminder of the Zoe's means of propulsion. And the front seats feature a decorative curved panel, defined by dark piping on each side of the backrest.

Tech highlights include the TomTom Live nav system's ability to describe a circle showing the car's operational radius on current charge, determining whether you can reach a nominated destination. It also taps you into weather updates, traffic danger zones and Renault Assistance.

Plus, the drive-management system can report on energy usage and assess driving behaviour, so lead foots have nowhere to hide.

Up front, storage and general usability are well thought out. There’s a handy shelf tucked underneath the centre console with two USB-C ports, while a tray above houses the fast wireless charging pad. You also get a sunglasses holder, two cupholders and decent-sized bottle holders in the doors, so it’s easy to keep things organised.

Seat comfort is a highlight, and the overall layout is clean and easy to live with, but the same can’t be said for the multimedia system. While the graphics are sharp and the touchscreen is responsive, functionality isn’t always its strong suit. Wireless Apple CarPlay and Android Auto are included, but CarPlay required reconnecting on every drive during testing and the digital radio and phone calls experienced noticeable signal dropouts. It’s the kind of friction that chips away at the day-to-day experience and starts to feel out of step with how polished the rest of the cabin is.

There’s also a heavy reliance on the screen for core functions. Climate control is integrated, which is fairly standard, but so too are things like headlight controls. It might suit those who are used to navigating everything through a screen, but needing to dig through menus to adjust something like auto high beam on the move feels like a step too far. Bring back buttons.

The second row is where the Sealion 8 really leans into its family-friendly brief. Space is generous, with enough width to comfortably accommodate three adults and the flat floor helps here too. There are three top tether points and two ISOFIX mounts, while charging is covered by a USB-A and USB-C port.

Amenities are a standout. The outboard seats mirror the front with heating, ventilation and massage functions, which quickly become a favourite, alongside dedicated climate controls, roof-mounted air vents and multiple cupholders. A set of sunshades would round things out nicely, but it’s otherwise a very accommodating space.

Access to the third row is less impressive. The manual slide and tilt mechanism feels a little heavy and fiddly to operate and the space itself is best reserved for kids. In practice, that means younger passengers will likely take the path of least resistance, as mine did and simply climb over the second row instead.

Amenities are fairly basic, with directional air vents and cupholders, but there’s no charging provision back there. You do, however, get two top tether points and ISOFIX mounts, which will be a plus for larger families.

Around the back, the boot is a practical, usable space with a wide opening and flat loading floor. With all three rows in place, there’s 270L on offer, which is enough for a few school bags or a grocery run, expanding to 960L with the third row folded. There’s no spare tyre, just a repair kit, which may be a consideration for regional drivers. A 12-volt socket and powered tailgate round things out in this grade.

Like most compact hatches the Zoe offers plenty of space up front and gets a bit squeezy in the back. Although the first surprise is that there's no height adjustment for either front seat.

Happily that wasn't a big issue. At 183cm I was still able to find a good driving position, with storage running to two cupholders (one small, one laughably tiny), plus a pen slot and two oddments trays in the centre console. The second of those trays houses a 12-volt outlet, SD card slot, 'aux-in' jack and USB port.

There are small bottleholders and storage pockets in each front door, a medium-size (7.0-litre) glove box with an open tray above it, and a small tray on the lower part of the dash on the driver's side.

Rear head and legroom is passable for a car of this size, but storage is limited to modest door bins and a single cupholder at the back of the centre console.

However, it's cargo space where the Zoe really raises eyebrows, with 338 litres available (to the parcel shelf) with the single piece rear seatback (as in, it doesn't split-fold) upright.

That's enough to easily swallow our three-piece hard suitcase set (35, 68 and 105 litres), or the CarsGuide pram. In fact, we were able to fit the largest suitcase and the pram at the same time, which is mighty impressive for a city-sized hatch. Push the rear seat flat and space grows to 1225 litres (to the roof), which is heaps.

Carpeting for the boot has been sourced from the cheap 'n' cheerful bin, but there are D-shaped anchor shackles, decent lighting and handy bag hooks back there.

The boot's unlikely volume is partly due to the absence of a spare of any description, a repair/inflator kit being your only option. And in case you were wondering, towing is "prohibited" (Renault's word, not mine).

Built at Renault's Flins plant, 40km west of Paris, on the same line as the Clio, the Zoe's offered in two grades; Life ($47,490, before on-road costs), and Intens ($49,490 BOC) as tested here.

That's big bucks for a little car. At just under $50,000 you're looking at internal-combustion competitors like the Audi A3, BMW 1 Series, and Merc A-Class. And while the Zoe's a long way from spartan, it's an equal distance away from luxurious.

That said, the standard features list includes, climate control (with remote 'pre conditioning' activation), 16-inch 'Black Shadow' alloy rims, cruise control, 3D Arkamys audio (with DAB radio, voice recognition, two 'boomer' speakers, two rear bi-cone speakers, and two tweeters), 'Renault Smartkey' keyless entry and start, auto headlights, and rain-sensing wipers.

Plus, you also get rear parking sensors, a reversing camera, the 7.0-inch 'R-Link' multimedia system (with 'Text to Speech' function), one-touch driver's window (the base Life grade misses this), a leather-trimmed steering wheel and gear knob plus black and grey cloth trim (with snazzy contrast stitching).

The DRLs may be LED but the headlights are halogen (a sure sign of this car's age), Apple CarPlay and Android Auto are MIA, and metallic paint, as per 'our' car's 'Zircon Blue' finish is $550 extra. 'Glacier White' is the only no-cost option from six available shades.

The BYD Sealion 8 Premium is all-wheel drive and pairs a 1.5-litre, four-cylinder, turbo-petrol engine with two electric motors, one on each axle. Combined outputs sit at a hefty 359kW and 675Nm, which comfortably out-muscles its key rivals.

Those figures do drop back to a more modest 110kW and 220Nm when running on the petrol engine alone.

Performance is strong for a large family SUV, with a claimed 0-100km/h sprint time of 4.9 seconds. You can toggle between pure EV and hybrid modes depending on the drive, which adds a layer of flexibility that suits short daily trips and longer highway runs.

The Zoe is powered by Renault's R90 synchronous electric motor, producing 68kW from 3000-5000rpm and 225Nm from step-off. Drive goes to the front wheels through a single reduction gear auto transmission.

Claimed acceleration for the city-specific 0-50km/h run is a handy 4.0sec, with the more grown-up 0-100km/h sprint taking a leisurely 13.2sec. Flat biscuit is 135km/h.

Charging is handled via a Type 2 CCS port, with support for up to 11kW on AC and up to 74kW on a DC fast charger. BYD claims a 30 to 80 per cent recharge can be done in as little as 20 minutes under ideal conditions.

The 35.6kWh lithium iron phosphate (LFP) battery is a standout, delivering a claimed electric-only driving range of 152km on the NEDC cycle. That figure is on the optimistic side compared to WLTP testing, but even with that in mind, it remains an impressive number for a plug-in hybrid of this size.

With a full battery, the combined fuel consumption is rated at just 1.0L/100km, translating to a theoretical driving range of over 1000km. Real-world results will vary depending on how often you’re able to charge and the type of driving you’re doing, but after a week that included a fair stretch of highway driving, my trip computer was showing 6.3L/100km. Overall, it’s a solid result, particularly for something with this level of performance.

None. Next question...

You can have the argument about fuel consumed and source emissions produced in generating the energy required to charge the Zoe's battery, but the fact is this car doesn't consume any fossil fuel and produces zero tailpipe emissions. Helped by the fact it doesn't have a tailpipe.

When launched in 2016, the Zoe's upgraded 41kWh 'Z.E. 40' high-energy lithium-ion battery ranked as the highest energy density automotive unit available.

Developed in collaboration with LG Chem in South Korea, it houses 12 modules (of 16 cells each) for a total of 912 individual cells and weighs in at 305kg.

Renault lists a driving range of 403km for the New European Driving Cycle (NEDC), with a real-world number of 300km a more realistic estimate. And that's almost exactly the range we achieved over a mix of city, suburban and freeway running in seven days with the car. Using overnight electricity rates, a full charge should average less than $8.00.

The Zoe's on-board 'Chameleon' charger allows it to be charged using different power levels (single or three-phase) through the same socket, from 3kW up to 22kW. A Type 2 charging cable (6.5m) for wall box and public charging points (in a natty canvas Z.E. bag) is included with the car.

According to Renault, a wall-box charger (not included with the car) is typically $1600 to $2000 for a residential installation and a mid-range 11kW unit will allow you to charge up in around four hours. High-powered 'Fast' and even juicier 'Rapid' charging points would reduce that time appreciably.

The dash indicator displays charge level and remaining range calculated over the last 200km of driving. A reset function can drop that to an average of the last 30km.

We'll touch on it further in the Driving section but regenerative braking, low-rolling resistance tyres, and 'Eco' mode (reducing air-con load and motor output) are big contributors to maximum range.

And while cabin cooling comes courtesy of a conventional a/c unit, heating is far more exotic. The Zoe's 'Heat Pump' system traps calories in the ambient air outside the car, with a pump compressing and heating them, then directing the heated air into the car, with no impact on range. Super clever.

On-road performance is where things become a bit of a mixed bag. There’s no denying the Sealion 8 Premium is quick and it leans more heavily into its EV character than many large plug-in hybrids. It’s quiet in hybrid mode and responsive off the mark, which makes it easy to keep pace in traffic and overtake when needed. For something of its size, it also does a good job of masking its weight on the move.

Regenerative braking is offered in two levels, but even the stronger setting feels fairly mild. The upside is smoother low-speed driving, with none of the abruptness you sometimes get in hybrids, and it does still recover a decent amount of energy, particularly on longer descents.

Where it falls short is in its overall dynamics. The steering and suspension are tuned for comfort, which results in a soft, slightly floaty feel on the road. It’s not unpleasant and around town it actually suits the car’s brief, but there’s a noticeable lack of feedback and control if you’re expecting something more composed.

Visibility and driver positioning also take some getting used to. The forward view is decent, but the pillars are quite thick and it can be difficult to find a driving position that doesn’t feel a little enclosed.

Judging the edges of the car isn’t always intuitive, and while the 360-degree camera is clear, its perspective can feel slightly off. Objects tend to appear much farther away than they are, which isn’t the most reassuring combination when you’re trying to manoeuvre in tighter spaces.

Some believe cars have a soul, but the Renault Zoe expresses its feelings with a distinctive accent, the car's 'Z.E. Voice' function giving an audible warning to pedestrians up to 30km/h (when wind and tyre noise take over).

The whirring hum sounds like The Beach Boys warming up the theremin for a rendition of 'Good Vibrations'. Spooky and fun in equal measure.

Like all electric cars the Renault Zoe accelerates quickly from rest, thanks to the motor's ability to deliver maximum torque (225kW) from step off.

At 1480kg (battery 305kg) the Zoe is 177kg lighter than an equivalent Clio, so it's snappy in its natural city habitat, but thrust begins to taper off markedly around the 55-60km/h mark.

The single-speed, reduction gear automatic transmission combines with the motor's sewing-machine smoothness to provide close to perfect drive delivery.

Sitting on the same 'B platform' as the Clio (and 20 other Renault–Nissan–Mitsubishi Alliance models) the Zoe features a strut front, beam rear suspension set-up.

Ride comfort is surprisingly good for such a small hatch, and the battery's location under the floor sets up a centre of gravity 35mm lower than the Clio's, so despite a 59 per cent front/41 per cent rear weight distribution, the car feels well planted in corners.

...the dash graphic – a blue AA-style battery surrounded by rising rings of energy – is reminiscent of 'the machine man' animating in Fritz Lang's Metropolis.

The standard 16-inch alloy wheels are shod with Michelin Energy E-V low-rolling-resistance tyres (195/55), which won't win you pole on a qualifying lap, but are commendably quiet.

There are three driving modes, with the dash graphics aligning to each – Eco (green), Neutral (blue), and Dynamic (violet).

But ECO mode should be reserved for hardcore environmental warriors only. Press the console-mounted button and power from the motor is reduced and air-con output is limited.

It may increase range by a claimed 10 per cent, but what price your sanity? This setting sucks out the car's will to live, and thankfully a second press of the button or pinning the throttle pedal to the floor sees full-strength service resumed. Phew.

The regenerative deceleration and braking system distributes braking force between the clamping of the brake pads and the engine on over-run to maximise battery charge.

While the BMW i3's regen system will have you head-butting the steering wheel (not really) when you get off the throttle, the Zoe's system is more subtle, and watching the dash graphic – a blue AA-style battery surrounded by rising rings of energy – is reminiscent of 'the machine man' animating in Fritz Lang's Metropolis.

Speaking of brakes, the fronts are relatively delicate 258mm vented discs and the 9.0-inch rear drums look like miniature versions of the elaborately fluted units found on 1920s Grand Prix racers. They're beautiful and work well.

Some niggles. The wipers skip and stutter in light rain, the lightweight doors feel clangy when you close them, and the R-Link multimedia system is annoyingly flaky when recognising content (or not) via Bluetooth or USB from a mobile device.

The Zoe hasn't been assessed by ANCAP but was awarded a maximum five-star ranking by EuroNCAP in 2013, with annual reviews allowing it to maintain that score through to April this year.

Active crash prevention tech includes ABS, EBD, EBA, ESC, traction control, tyre-pressure-loss sensors, rear parking sensors and a reversing camera.

But forget about more recent systems like AEB, lane-keeping assistance, blind-spot monitoring, cross-traffic alerts or adaptive cruise.

Interestingly, the Zoe continuously monitors the state of each cell in the battery pack and will switch off current immediately if it senses an overheating-style abnormality.

If an impact is unavoidable the airbag count runs to six - driver and passenger front, front side (head and thorax), and full-length side curtain.

There are three top tethers and two ISOFIX positions for child seats/baby capsules across the back row, and all seats feature Renault's 'Fix4Sure' anti-submarining design.

BYD offers the Sealion 8 with a six-year/150,000km warranty and an eight-year or up to 160,000km battery warranty. Both terms are competitive for its class.

Service is recommended every 12 months/20,000km with each workshop visit averaging a solid $596 for the first five years (year four is $1360). Accessing a BYD service centre is fairly easy as there are around 70 centres nationwide now.

BYD recommends premium unleaded petrol (95RON) to be used for the Sealion 8.

According to Renault, the R90 motor is "maintenance-free", waterproof and requires no lubrication, with servicing costs "20 per cent lower than an equivalent ICE (internal combustion engine) vehicle."

Despite that, servicing is recommended every 12 months/30,000km for an estimated cost of $231 each time.

Warranty is three years/unlimited km with 24-hour roadside assist included for the first year, and three after that if you have your car serviced at an authorised Renault dealer.

The battery is covered by a separate five year/100,000km warranty.
