BYD Sealion 8 vs Peugeot Boxer

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.

It has its faults like any vehicle but it’s a competent all-rounder, that combines sub-$50K pricing with a big payload capacity, mostly user-friendly design, improved safety and a compelling warranty. It also faces stiff competition in the 3501-8000kg GVM class, particularly from rivals with an automatic option. 

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.

It comes ready for work with hard-wearing black plastic in the most vulnerable places for scrapes and dents, including the front and rear bumpers and down the sides. The same black finish can be found on the window surrounds, door handles, huge door mirrors (which would not look out of place on a Kenworth) and the housing for the high-mounted third brake light.

It’s a large vehicle measuring 5413mm long, 2050mm wide and, thanks to the conspicuously high roof line, stands 2522mm tall. So, like numerous rivals in this weight class, it can’t access most shopping centre and underground carparks.

The front-wheel drive chassis, with its 3450mm wheelbase and 12.6-metre turning circle, features a simple and rugged combination of coil-spring strut front suspension, four-wheel disc brakes, power-assisted rack and pinion steering and single-leaf/solid beam rear suspension. Long rubber bump-stop cones, attached to the underfloor above each end of the rear axle, provide extra support when the springs compress under heavy loads.

The steel bulkhead, which separates the cabin from the cargo bay, insulates the driver/passenger from cargo bay noise and doubles as a robust cargo barrier. Its window is large enough to allow the driver to make a quick over-shoulder glance at any time to check the load is secure.

Criticisms? The relatively small 5.0-inch media screen can make the reversing camera’s vision difficult to see in detail. The height adjustment on the driver’s seat, using two levers on the lower right side, is clunky to operate. And although the rear barn-door windows are heated, there are no wiper/washers, which we didn’t get to test in wet conditions, which is most unusual for Melbourne.

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.

The Boxer 160’s 1865kg tare weight and 3510kg GVM results in a sizeable 1645kg payload rating. However, we always quote kerb weights (full tank of fuel) rather than tare weights (10 litres of fuel) to keep things consistent.

So, in this case, adding the missing 80 litres of diesel (67kg) results in a kerb weight of 1932kg, which reduces the payload by the same amount to 1578kg. That’s still almost 1.6 tonnes which is more than ample for this category. It's also rated to tow up to 2500kg of braked trailer and, based on European figures at least, can do this with a full payload.

The cargo bay provides a competitive 11.5 cubic metres of load volume and 10 sturdy load-anchorage points. Its floor, which is 3120mm long and 1870mm wide with 1420mm between the wheel housings, can  accommodate two 1165mm-square standard Aussie pallets or three 1200 x 800mm Euro pallets. There’s ample forklift access through the rear barn-doors with full 270-degree openings or sliding side doors with their big 1250mm openings.

The high roof cavity means even tall adults can stand inside with headroom to spare. It also provides a large and very useful open storage area over the driver’s cabin, which is ideal for storing ropes, straps, load-padding and any other gear a hard-working van might need.

Although the side doors and barn-doors are lined to mid-height, the cargo bay walls are unlined which leaves numerous cavities exposed that could make small items like pens, keys, phones etc disappear if they were dropped. The load floor is also unprotected.

Cabin storage options include upper and lower bins in each door, with the lower bins being wide and deep enough to hold several large bottles. There’s also a full-width map shelf that sits about forehead height for tall drivers, which is easy to access and can hold heaps of stuff.

The dashboard also has numerous storage choices including open shelves to the right of the steering column and underneath it, cup/small-bottle holders in the centre of the dash and on top a fixed clipboard with spring-loaded clamp. There’s also a glovebox with another large open storage bin below it plus even more storage, about the size of a baking tray, under the driver’s seat.

The Boxer 160 (which denotes its European horsepower or ‘PS’ rating) is available only with a 2.0 litre turbo-diesel engine and six-speed manual transmission, plus a choice of 4035mm long wheelbase or 3450mm standard wheelbase like our test vehicle, for a list price of $47,490.

It comes equipped with 15-inch steel wheels and 215/70 R15C tyres with a full-size spare, plus cargo bay bulkhead, hard-wearing rubber floor, 12-volt accessory socket and USB ports, height/reach adjustable steering wheel, two bucket seats with fold-down inboard armrests and lumbar adjustment and multimedia system with 5.0-inch touchscreen and sat-nav plus ample storage and more. There’s also AEB on the upgraded safety menu.

The only options available are three paint colours (Imperial Blue, Red and Aluminium Grey) in addition to our test vehicle’s standard Bianca White.

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 2.0-litre Blue HDI four-cylinder turbo-diesel engine, which meets the toughest Euro 6 emissions standard using AdBlue, produces peak values of 120kW at 3500rpm and 310Nm of torque at 1500rpm.

Peugeot claims this engine was tested for more than 10,000 hours, subjected to more than 1.3 million km of drive-testing and 16,000 thermal shock cycles (cold starting and accelerations), corresponding to 15 years of intensive use. In short, it should be tough enough. Transmission is a sweet-shifting six-speed manual.

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.

Peugeot’s official combined average is a fanciful 6.4L/100km. The dash readout was claiming a more realistic 9.0L/100km when we filled the tank after 282km of testing, which included more than a third of that distance lugging its maximum payload.

However, our own figure calculated from fuel bowser and tripmeter readings came in at 9.9L, which is more than 3.0L/100km above the official figure. Even so, sub-10L economy is very efficient  for a vehicle of this size, so based on our figures you could expect an excellent real-world driving range of around 900km from its big 90-litre tank.

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.

You sit up high with the huge windscreen providing a commanding view of the road ahead. Clear eye-lines to the large door mirrors (with wide-angle mirrors in their lower thirds) provide ample coverage of side and rear traffic.

Vision through the central rear-view mirror is also relatively clear compared to the cluttered views found in numerous rivals we’ve tested. The join of the barn-doors obscures the mirror’s central portion, but the driver still has a good view of what’s behind.

The fold-down inboard arm-rests combined with the door contours provide balanced support for arms and elbows to reduce strain on neck and shoulders. This support is particularly good for the driver, as it also allows your hands to rest comfortably on the steering wheel.

There’s negligible cargo bay noise thanks to the bulkhead. However, engine noise is noticeable and tyre noise can be quite intrusive, particularly at highway speeds on coarse bitumen surfaces. Cruising in top gear results in a fairly relaxed 2100rpm at 100km/h and 2300rpm at 110km/h.

The engine, with maximum torque at 1500rpm, has good all-round performance and pulling power under heavy loads, but lacks the sharper throttle response of some rivals. Even so, the manual gearshift has a light but well-defined action combined with a light clutch pedal weight.

Steering is nicely weighted and the quartet of disc brakes have plenty of bite. Handling and stability are also good regardless of load. The rear suspension tuning is commendable when running without loads on bumpy roads, providing a surprisingly smooth ride given spring rates that are designed to cope with 1.5 tonne-plus payloads.

Our only gripes are that the driver’s seat’s adjustable lumbar support presses too firmly against the spine for our liking, even on its softest setting. We also detected a couple of rattles and squeaks on bumpy roads, which sounded like they were coming from the dashboard area.

There’s no ANCAP for this vehicle segment but the Boxer would probably score well if there was thanks to the latest features like video autonomous emergency braking, forward collision warning, lane-departure warning, LED daytime running lights, reversing camera, rear parking sensors and more. There’s also driver and passenger front and side-curtain airbags.

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.

The Boxer is covered by Peugeot's five years/200,000km warranty and scheduled service intervals of 12 months/20,000km, whichever occurs first. Capped-price servicing applies for the first five scheduled services with a total cost of $3445 valid until June 30, 2020.
