Volkswagen Polo vs BYD Sealion 5

What's the difference?

The Polo GTI faces tough competition in the form of Hyundai’s recently arrived, very good, and well-equipped i20 N, as well as Ford’s sleek and super-capable Fiesta ST. But as mentioned at the start, VW occupies the hot-hatch high ground with the GTI badge, and this upgraded Polo is loaded with features, dynamically outstanding and on the leading edge in terms of safety. Time will tell if the higher price, higher spec strategy is the right one, but there’s no doubting this updated Polo GTI is a compelling package.  

Note: CarsGuide attended this event as a guest of the manufacturer, with meals provided.

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.

Not exactly a massive change to the exterior of the Polo GTI with this mid-life refresh, but sharp-eyed car spotters will notice a new front bumper treatment including a revised lower grille, defined by a body-coloured border and flanked by LED driving lights.

The headlights have also been reshaped to mark the arrival of standard matrix LED beams, with the signature horizontal red keyline moves from the centre to the bottom edge of the upper grille. A continuous LED strip across the nose stands the car apart after dark.

Previously part of the GTI’s ‘Luxury Pack’, the ‘Faro’ design 18-inch alloys fill the wheel arches nicely, and overall the car’s compact, tightly wrapped body and finely chiselled lines are familiar.

At the back, the LED tail-light clusters have been extended laterally into the hatch door, but the car’s fundamental shape is unchanged. 

Inside the dash layout is the same, although the centre of the sports steering wheel has been massaged into a more organic shape with the airbag/horn now an oval rather than a circle.

The rest of the interior is relatively understated in typical VW fashion, the neatly sculpted sports seats trimmed with traditional ‘Clark’ tartan cloth on the cushion and backrest centres. And ‘Kings Red’ inlays in the dash, centre console and front door trims, are a reminder of the car’s heritage and sporty intent.

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.

At just under 4.1 metres long the Polo GTI is a decidedly compact hot hatch, but thanks in no small part to a relatively lengthy (2.6m) wheelbase, interior space is impressive.

The driver and front passenger have plenty of breathing room, and the rear is remarkable. At 183cm, sitting behind the driver’s seat set to my position, I enjoyed ample legroom, and more than enough headroom.

Width is another story, because while two adults will be fine in the back, there isn’t enough space for three to sit in comfort for any length of time. 

Storage options in the front include a small lidded box between the seats (which doubles as an adjustable armrest), two cupholders and various oddments spaces in the centre console, as well as the wireless charging bay in front of the gearshift. 

There are also pockets in the doors with room for (medium) bottles, a decent glove box, a shallow drawer under the passenger seat, and an overhead drop-down tray for glasses.

Map pockets on the front seat backrests, and small bins in the doors add extra practicality, but there’s no fold-down centre armrest or individual ventilation control for rear seaters. 

For connectivity and power, there are two USB-C ports in the front, plus another two in the rear, as well as a 12-volt socket in the front centre console.

Boot space is a healthy 305 litres (VDA) with the 60/40 split-folding rear seats upright, that number growing to 1079L with them folded down. 

Tie down anchors are handy for strapping loose loads, while shopping bag hooks help keep smaller bundles under control. And be aware, the spare is a space-saver.

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 Polo GTI is powered by a version of Volkswagen’s 2.0-litre (EA888) four-cylinder turbo-petrol engine, driving the front wheels through a six-speed dual-clutch auto transmission.

The iron block/alloy head unit uses direct- and port-injection, variable valve lift on the intake side, and variable valve timing on the intake and exhaust sides to produce maximum torque of 320Nm from 1450 to 4390rpm, at which point peak power of 147kW takes over from 4390-6000rpm.

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.

VW’s official fuel economy figure for the Polo GTI on the combined (ADR 81/02 - urban, extra-urban) cycle is 6.5L/100km, the 2.0-litre turbo four emitting 150g/km of CO2 in the process. Not bad for hot-hatch with this kind of performance. 

Minimum fuel requirement is 95 RON premium unleaded and you’ll need 40 litres of it to fill the tank. Using the official consumption figure that translates to a range of 615km.

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.

The Polo launch drive program covered around 150km of city, suburban and freeway running from inner Sydney, through twisting B-roads to the city’s south, and sprawling semi-rural areas further west, topped off with a closed track session at the Luddenham Raceway.

Weighing in at a fraction over 1.3 tonnes, with 147kW/320Nm sent to the front wheels, the Polo GTI is capable of sprinting from 0-100km/h in 6.8 seconds, which is satisfyingly quick.

And the 2.0-litre, four-cylinder turbo-petrol engine’s dyno sheet must be a thing of beauty with maximum torque available from from 1450 to 4390rpm, and peak power picking things up at precisely the end of that plateau, remaining on tap all the way to 6000rpm.

So, mid-range punch is always there, and the six-speed ‘DSG’ dual-clutch auto delivers rapid, precise shifts, with wheel-mounted paddles dialling up the fun factor when you want to shift ratios yourself.

Combined engine and exhaust noise is agreeably rorty without tipping over the annoyance threshold, although the high-performance 215/40 Continental ContiSportContact rubber transfers a fair amount of rumble on coarser surfaces.  

The base suspension set-up is strut front/torsion beam rear, with the standard ‘Sport Select’ system built around switchable dampers, offering the choice of ‘Normal’ and ‘Sport’ modes. 

Normal is nicely composed with comfy compliance over longer undulations as well as higher frequency bumps and dips. But if the red mist descends and you’re ready for some fun the (noticeably firmer) Sport setting buttons everything down that bit more. 

As well as the damping, throttle response is faster, the DSG picks up the pace as does the steering. Even the exhaust is enhanced, although it’s via the synthetic ‘Sound Actuator.’ Boo!

Balanced and predictable in quick cornering, the Polo GTI’s electro-mechanically assisted steering is precise and beautifully weighted, with great road feel. And the car’s ‘Extended Differential Lock’ uses the traction control and braking systems to minimise wheel spin, maximise traction, and help limit understeer.

On top of all that, the carefully sculpted sports seats deliver secure location without compromising comfort, and the grippy sports wheel feels great.

Braking is by ventilated discs at the front with solid rotors at the rear, and even under the pressure of a flat-out track session (moderated with the help of some admirably patient tame racing drivers) they remained progressive and firm.

In more civilised surroundings the Polo’s size and excellent all-around vision (not to mention a clear reversing camera) make it a cinch to park. The combination of on-screen touch controls, and physical dials for the multimedia system is welcome. And the connection for Apple CarPlay and Android Auto is wired or wireless which is handy for those who prefer the surety of a wired connection or the flexibility of one less cable in their life.

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.

Volkswagen Australia covers the Polo GTI with a five-year/unlimited kilometre warranty, which is now the volume market standard.

The paint is warranted for three years/unlimited kilometres, “Through Corrosion” is covered for 12 years/unlimited kilometres, and 12 months roadside assistance is included.

Servicing is required every 12 months or 15,000km, with prices over the first five years ranging from a low of $455 to a high of $1498, the average per service coming out at $701, which is a pretty solid number.

Capped price servicing is available, however, over five- and three-year plans. Paying up-front for five years results in a $765 saving over pay-as-you-go.

A nice side benefit is the ability to fold servicing costs into the vehicle’s financing at the time of purchase, and the plan is transferable if you decide to sell the car before the five or three years is up.

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.
