Holden Astra vs BYD Sealion 5

What's the difference?

The Astra's biggest problem is probably the Holden badge. Despite the company's best efforts, some buyers are wary of the company's longevity and some of the other cars in the range do the Astra no favours - Trax, Colorado and Barina feel cheap, because they are. The Astra isn't cheaply made and holds up very well in excellent company.

Cars that don’t always appeal to enthusiast buyers are often seen by manufacturers as a way of not bothering with the dynamics. Good enough is, apparently, good enough. Thankfully, BYD hasn’t taken that path here and the local suspension tweaks have turned what could have been a me-too product into a bit of a dynamic class leader. And even if buyers can’t verbalise the benefits of that, they will still be subliminally enjoying them with every kilometre.

The other stand-out feature is the price-tag which represents an awful lot of car for the money. And, in such a price-sensitive market as this one, that will get the BYD over the line for a lot of families. That it also offers a vastly better driving experience simply makes the value equation – and the purchasing proposition – even stronger.

The Astra is a sleek if slightly anonymous-looking thing. Having said that, it's a really nice design that looks more expensive than it is. That's important in this segment. Holden is at pains to tell us it's from Germany (the Astra is manufactured in Poland) and it does look Euro-influenced. Despite its coupe roofline, it's an easy in-and-out proposition but does sit a little lower than, say, an i30.

The odd blacked-out section of the C-pillar takes a bit of getting used to but the sheetmetal is otherwise faultless and well put together.

Inside it's a sea of grey plastic and various shades thereof, but again, it hangs together really well and is a welcome change from the Teutonically angular Golf. The materials are largely reasonable, but for some reason the stalks feel flimsy to touch and use.

The cloth trim is hardy but comfortable and I was grateful for its relative coolness versus what you might expect from the textile leather you're more likely to get at this level.

The interior of the Sealion 5 feels pretty well-made and there are soft-touch surfaces on most of the touch-points. The steering wheel, too, is thick and chunky and nice to hang on to. But there’s a lot going on in terms of different colours, textures and surfaces, and it can all look a bit busy, despite the high-tech boardroom overall flavour. It’s also worth mentioning the trim material is synthetic but does a great job of looking and feeling like real leather.

Externally, there’s not a lot to grab the eye. Sure, it’s not an unpleasant looking vehicle, but neither does it stand out from the mid-size SUV pack. At least BYD decided against those cheap-looking plastic tack-ons on each wheel-arch.

Riding in the front, there's room aplenty for passengers, with good headroom and a well-designed space to maximise what's available. Rear seat passengers do okay as long as the front occupants are being generous, but the seat itself is comfortable and there's even good headroom, despite the falling roofline.

Only the front scores cupholders, with the rear passengers making do with door pockets that might swallow a small bottle. There isn't an armrest or air vents back there either.

There's somewhere for one front occupant to put their phone, a horizontal slot that doesn't like phones with covers or the larger format iPhones or Androids. If your phone does fit (iPhone Xs do, as it happens), it's useful because it's in your eyeline, although a bit untidy if you're plugged into the USB.

The boot starts at a class-compeititve 360 litres, rising to 1210 when you fold the seats down.

Here’s the other big shock relative to the price-tag of the Sealion 5: This is not a small car. Based on the price, you might have been thinking the vehicle would be a compact SUV. And you’d have been wrong. This is a proper mid-sized SUV with room for five and luggage and an overall length of 4.7 metres and change. And to put that into some kind of perspective, that’s just 30mm shorter than the Sealion 6 which costs about $9000 more at its starting point.

The wheelbase is long, too, and the 2712mm between the axles helps make the interior even more spacious. That means there’s lots of stretching room in the front, but also that a grown adult can comfortably sit in the back seat behind another grown adult at the wheel and still have enough room in every direction. The window sills are commendably low in the rear seat, too, ensuring even littlies can see out.

The biggest problem in the back is that the seat cushion is a bit flat, but, like the front chairs, it’s still pretty plush.

With all five seats in place, the Sealion 5 boasts 463 litres of luggage space and the cargo area is well done with storage pockets at each side, a light and an under-floor tray designed to transport charging cables and a tyre repair kit. Yep, that’s right, there’s no spare tyre of any sort here. No surprise, really.

Fold the rear seat down and you’re suddenly looking at 1410 litres of cargo space and your SUV is now a panel van.

As well as the dual-zone climate control, the Sealion 5 also offers a single USB -C and a USB-A charging port in the front and rear compartments.

The Sealion 5 also offers a V2L (Vehicle to Load) function, meaning it can power camping or on-site work equipment and even act as your home’s battery.

The plug-in hybrid in question is the BYD Sealion 5. It has a claimed EV-only range of better than 100km, relatively quick charging, a decent sized battery, adequate performance, enough interior space for a family, good safety and lots of equipment. Oh, and it costs just $33,990, before on-road costs, in its entry-level Essential form. Incoming!

Equipment-wise, that sub-34K sticker gets you a 10.1-inch central info-screen, an 8.8-inch driver display, digital radio, a six-speaker stereo, wireless connectivity for Android Auto and Apple CarPlay and dual-zone climate control.

Throw another four grand on the table and you move up to the Premium version which adds plenty of kit for the $37,990 ask. That includes a panoramic sunroof, automatic tailgate, roof rails, heated and electrically folding mirrors, one-touch power windows, a six-way powered drivers seat and four-way powered co-pilot’s chair, a heated and ventilated driver’s seat and wireless charging.

The step up from Essential to Premium also includes a battery upgrade, and we’ll cover that off in the Under the Bonnet section below.

The whole Astra range is turbo, but here in the cheaper seats it's a surprisingly capable 1.4-litre unit with 110kW and a healthy 240Nm. Power finds the road via the front wheels and a six-speed automatic. It's an otherwise unremarkable technical story, with start-stop to help cut fuel use.

The Astra is rated to tow 750kg unbraked and 1200kg braked.

Both variants of the Sealion 5 have the same driveline – mostly. They each use a 1.5-litre petrol engine teamed with a single electric motor, both driving the front wheels. Unlike the bigger Sealions, there’s no all-wheel drive version. Power peaks at 156kW and torque at 300Nm.

Why a non-turbocharged engine? BYD tells us the non-turbo engine helps keep cost out of the vehicle and, since the engine really only runs to power the electric motor and charge the batteries, it does so at a relatively constant engine speed, negating the need for a wide spread of petrol power.

The only major difference is that the Essential version has a 12.9kWh battery-pack, while the Premium gets a bigger, 18.3kWh pack for longer range, but precisely the same output and, therefore, performance.

A single-speed transmission is part of the BYD driveline package, also made possible by the fact that the vast majority of the driving of wheels is done by the electric motor.

Holden claims the Astra will drink standard unleaded at the rate of 5.8L/100km on the combined cycle.

Our time with the car, which was a 70/30 mix of suburban and highway, yielded 8.3L/100km, and it's worth noting it was stinking hot for most of the time, so the air-con had to work hard.

The fuel tank is a little on the small side at 48 litres, between five and 10 litres smaller than some of its competitors, like i30 and Golf.

The Premium’s bigger battery claims to up the official NEDC range from the Essential’s 71km to 100km. BYD reckons with the 52-litre fuel tank brimmed and the car operating at its claimed 1.2 litres per 100km efficiency, the range of either version is just on 1000km. In the real world, that’s likely to be closer to 800km (especially with some highway running thrown in) but it’s still one heck of a solution to range anxiety.

There’s no DC charging function for the Sealion 5, so forget about commercial fast chargers. But on a 3.3kW AC power outlet, the maker claims the Essential can reach full charge in under four hours, while the Premium’s bigger battery will take under six hours to fully charge. A Type 1 charge cable is included.

I'm going to get my biggest gripe with the Astra out of the way first - the driving position is rendered awkward by the pedal placement. Every other part of the driving experience is perfectly fine, with good adjustment in the seat and steering wheel but the pedals are Not Right. The transition from accelerator to brake means a big lift of the right foot rather than a sideways shuffle and that gets boring. Perhaps I'm getting old and my knees are weak, but I ended up left-foot braking for a lot of the time.

On with the show. The Astra's 1.4 litre turbo is a punchy thing, more than vaguely reminiscent of Peugeot's excellent 1.2 in the 308. The six-speed auto isn't quite as well sorted, occasionally lurching a bit on light throttle like a dual-clutch. The pay-off for that is crisp shifts and a positive feel for most of the time.

The thing about the Astra is that it really takes it to its competition from behind the wheel. It feels almost as good as a Golf, i30 and arguably is as good as a Mazda3 thanks to its extra torque and better refinement.

It's very quiet, composed and is good fun if you like that sort of thing. Otherwise, it's streets ahead of the Corolla which continues to sell like it's going out of fashion.

You don’t have to drive very far to realise that the local input into the Sealion 5’s suspension and steering have been worth the effort. BYD Australia has a local engineering team on call these days, and it shows here.

Actually, the steering is not the highlight; it has some weight but not a whole lot of feel, or, indeed, feedback for the driver. The ride and handling combination is what stars. Obviously well-damped, the suspension allows for a ride that is both complaint and quiet, without causing the car to wallow around like some jacked-up designs can with their higher centre of gravity.

In fact, the BYD is athletic to the point where keener drivers will find it an entertaining drive; hardly something that can be said for the majority of medium SUVs.

Performance is strong without being overwhelming and even though the Sealion 5 has that signature electric-drive feeling of effortlessness, the accelerator pedal has been calibrated to avoid the neck-snapping surge of grunt off the line. As such, it emerges with a fairly flat acceleration curve, and no hint that the petrol motor is cutting in or out.

Until, that is, you bury the throttle all the way at which point the petrol engine takes a few second to join in. And when it does, it’s pretty vocal – shrill, almost – as it catches up with the rest of the car and starts directly driving the wheels. To be fair, though, this is not going to be a common occurrence in everyday life thanks to the flexibility of the petrol-electric system for 99 per cent of circumstances.

On the move, the cabin is perhaps most notable for its soft, plush seats that are a nice change from the church pews of some manufacturers. And although the driving position is about right, taller drivers might prefer a steering column that extends out another few millimetres.

The driver display screen is another source of annoyance. It’s pretty small and contains lots and lots of information, to the point where the typeface is too small to be read on the run by anybody who relies on reading glasses.

Passive safety in the Sealion 5 starts with no fewer than seven airbags including full-length side-curtain bags. 

There’s also a front-centre airbag, something we’d like to see in more cars, particularly at this price-point. Child restraint points in the rear seat are the ISOFIX type.

The BYD gets pretty much the full suite of driver aids, including autonomous emergency braking, blind-spot monitoring, rear-cross traffic alert with active assistance, stability control, active cruise-control, traffic-sign recognition, front and rear collision warning and tyre pressure monitoring.

The Sealion 5 also incorporates a driver-attention monitor which seems better calibrated than some earlier efforts from some of the Chinese carmakers. Also improved in calibration terms is the lane-keeping assistance which is still too violent for our tastes, but more subtle than some of the competition’s systems. But while the savagery of this system has been toned down, it appears to have been at the expense of sensitivity and, time and time again, the cameras missed road markings that were faded or dirty.

The major safety benefit in paying more for the Premium variant is the addition of front parking sensors and a 360-degree camera instead of the Essential’s simple reversing camera.

The Sealion 5 has not been ANCAP tested as yet, although BYD says this is largely down to ANCAP’s scheduling rather than any hesitance on BYD’s part.

Holden's three year/100,000km warranty includes roadside assist for the duration. You can also extend the warranty by up to three years or to 175,000km, for an extra cost.

Servicing is scheduled every nine months or 15,000km. Holden calls its fixed-price servicing 'Know Your Price' and it applies for the first six services (63 months or 105,000km). The first four services are set at $249 each, and the final three $309.

Like other BYDs, the Sealion 5 comes with a six-year/150,000km warranty. Some of the competition have unlimited kilometre warranties, but to be honest, 150,000km in six years is going to be beyond the need and aspirations of most owners.

The EV battery is covered by an eight-year/160,000km warranty, and let’s not forget, BYD was a battery manufacturer before it started making whole cars. Certainly, the company is very bullish about the quality and safety of its 'Blade' battery technology, claiming it easily passes the technically-daunting 'nail-puncture' test.

BYD plans to have capped-price servicing for the Sealion 5, but no pricing announcements have been made yet.

Servicing also falls into line with other BYD models, so that means 12 months or 20,000km intervals.
