Toyota Prius C vs BYD Sealion 5

What's the difference?

It's as if the the future is firmly rooted in the past at Toyota. The Prius is still undoubtedly clever, frugal and easy to drive, but it is feeling so old in places that the bad had begun to weigh on the good. If you're a tech-head or have a right foot crafted from lead, then there's nothing to see here. But if the thought of saving money at the bowser sets your heart aflutter, then step right this way.

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 good news is that it doesn't look quite so quirky as the full-size Prius. The not-as-good news is that it's still no beauty-contest winner. Not helping matters was the fact our test vehicle was painted in a retina-burning yellow (they call it Hornet Yellow, and it's new for 2018) that looked almost nuclear.

Viewed front on, the blacked-out section of grille and bumper gives the littlest Prius a vaguely manta ray-shaped front-end, while the headlights climb both upwards and back into the body, lending a sense of sportiness to this very unsporty hybrid. From the back, the chunky bumper, vertical taillights and rear windscreen spoiler all add a little attitude to the design.

Inside, you'll find a small but premium-in-places space, with a gloss-black stereo surround that angles the main controls toward the driver, while the digital driver's binnacle is pushed toward the centre of the car, displaying speed, fuel and other key info above the stereo, rather than in front of the steering wheel.

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.

Not very. This is a Yaris-based city car, let's not forget.

That said, it never feels cramped up front, with enough shoulder and headroom to ensure you feel separated from your fellow passengers, where you'll also find two cupholders, and an infuriating USB connection housed in the touchscreen - so your cord dangles from the dash when connected.

Climb into the back, and you'll find yourself in a pretty snug space. Sitting behind my own (5ft-8inch) driving position, it's only the scalloped back of the driver's seat that affords me any clear air between my knees and the seat in front, and the space behind my head and the roof lining is minuscule, too. But again, we're talking city car space here, so you can't expect to lounge about back there.

The ambience in the backseat leaves a little to be desired, though. The door trim pushes into the passenger space, and the plastics used in the rear are rock hard. There's a single cupholder to share, and a seat-back pocket on the rear of the passenger seat, but that's it; there's no vents, USB or power sources. There's no bottle-room in the rear doors, either.

An easy-access boot space will swallow 260 litres with the 60:40 rear seats in place. And there are two ISOFIX attachment points, one in each window seat in the back.

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.

Under that little hood lives a 1.5-litre, four-cylinder petrol engine good for 54kW, which pairs with a 45kW electric motor. Toyota lists combined outputs at 74kW at 4800rpm and 111Nm at 4000rpm.

That hybrid setup partners with a CVT automatic, pumping power to the front wheels.

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.

If that last section didn't impress, this one surely will. The little Prius c will sip a claimed 3.9L/100km on the combined cycle.

That's very low, and the fact it accepts cheaper 91RON fuel makes it a very affordable car to run. Except... the onboard computers revealed a slightly less-impressive 5.1L/100km after my time with the car.

Emissions are a claimed 90g/km of CO2, which is very good.

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.

In much the same way that you don't buy an exotic performance car for its ability to run to the shops, you're unlikely to be buying the Prius for its ability to set your pulse racing.

But happily, it doesn't feel wobbly or disconnected, either. It's aided by being such a small package, and when you're not wafting silently about in electric mode, and you've coaxed that little petrol engine into life, it serves up more than enough poke to navigate the city, and even to leave the slow-reactors in your rear-view mirror at traffic lights.

The ride is good, too, feeling connected to the road below without feeling uncomfortable, although the little Prius does tend to track with the corrugations in the road, leaving you to wrestle it back into line. That's a job made easier by light and surprisingly direct steering, which feels tailor-made for the city.

Finally, the leather-look seats are comfortable, even over long distances, the razor-thin A-pillars make forward vision easy and it's a very simple thing to drive and manoeuvre  into parking spaces. And all of those are good things.

Not so good? Well, the entire drive experiences feels a little beige and emotionless, it can get noisy and there are parts of the cabin that feel downright cheap. Worst of all, though, is that for a car that once heralded the future, it's feeling very, very dated.

But there are some amazing quirks attached to driving an (almost) electric car, including the delivery of eco awards for using the least amount of fuel (they were awarded for 2.6, 3.2 and 3.6L/100km over as much as 25km - none of which occurred during my tenure). The hardest thing to get used to was the absolute silence served up in electric mode. I counted four seperate occasions when I walked away from the car with it still turned on.

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.

Toyota offers a three-year/100,000km warranty, while the batteries are covered for eight years or 160,000km. The car's six-month service intervals might sting a little, though, but with each service capped at $140 for the first three years, even taking two trips to the dealership a year isn't too expensive. Just annoying.

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.
