BYD Sealion 8 vs Toyota Prius C

What's the difference?

There’s quite a bit to like here. There’s plenty of equipment, and lots of choice in price, trim level and mechanical complexity.

The driving dynamics are fine if you’re not looking for anything sporty although the performance offered by the dual-motor variants must be considered excessive, even if it’s pretty exciting the first time.

Perhaps what’s missing from the Sealion 8 experience is anything that stamps the car as something special within its hotly-contested market segment. Which is another way of saying it offers up the same limitations, most notably in the third row accommodation and access.

You only need to drive a one-box people mover and utilise the rearmost seat, to understand that the two-box SUV, while a pretty marketable thing, is compromised once the passenger count exceeds five. Nothing new there, but nothing new in the BYD, either, to change that narrative.

At which point, the front-wheel drive variant emerges as the most pragmatic choice and probably the one that meets all the important family tasks headed its way for the smallest outlay.

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.

BYD has done its best to give the Sealion 8 its own character and vibe. In fact, it’s a pretty smart looking thing - although still very much a two-box wagon concept - and that’s no given when you consider how much some big SUVs can start to look like large blobs of nothing when you look closely.

There’s the usual Darth Vader stuff at the front, but in profile, the diagonal vent across the front door makes a bit of a statement. The 'plaited' motif of the tail-lights might be stretching things a bit, though.

Inside, the modern board-room feel is invoked by the angular lines and high-tech look and feel of the large info-screens. The panoramic sunroof of the Premium grade also helps brighten up an otherwise pretty dark space.

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.

BYD has made sure all three rows of the Sealion 8 are fit for purpose while attempting to make the rearmost row (traditionally the trickiest to get right) less of a downmarket place to be. With that in mind, both rear rows get air vents and climate-control adjustment for that part of the car. There's also a pair of USB-C charge ports in the second row and a single USB-C and USB-A port in the third row. The third row also has cupholders bult into the wheel arch on each side.

With the third row in place, there’s a decent amount of luggage space (270 litres) largely thanks to the Sealion’s five-metre overall length. There’s no spare tyre, but a puncture repair kit lives under the floor (as does the removable cargo blind) and the rearmost luggage space also incorporates a 12-volt socket and luggage hooks.

A pair of pull-tabs drop the headrests and then the entire split third row in a single movement, at which point you suddenly have a five-seater with a huge, 960 litres of luggage space. And if you need to cart gear over people, the second row also folds flat to open up 1960 litres of space.

Up front, the feeling of spaciousness is amplified due to the low scuttle height and what the aviation industry calls the glass cockpit (no analogue dials or gauges at all). The 15.6-inch central info-screen runs the usual apps and control displays but, thankfully, the climate control touch-controls are tethered to the bottom of the screen, so they’re always visible regardless of what else is going on.

The 10.2-inch driver’s display adds a head-up function in Premium trim and displays the usual array of information required to operate the vehicle. But even better is the steering wheel which features a thick, well-padded rim that looks and feels pretty luxe. It also houses the usual buttons for stereo, phone and cruise-control functions.

A really nice touch is the addition of an extra set of tilt controls on the inside of the passenger’s front seat, allowing the driver to control that seat to allow people in or out without leaving their own seat. Nice one.

It is, of course, the centre row of seats that will make or break a car like this for many families. Even though many clans will not use the rearmost seat much of the time, the central row will get a huge workout. So it’s nice to see that leg, foot and headroom are all sufficient for even growing teenagers. Again, the car’s overall length appears to be the key, but it’s also worth noting the centre row seat is comfy and supportive. The outboard positions in the second row also feature heating and ventilation functions.

The third row, however, follows SUV tradition by being strictly for smaller kids. Access past those huge wheel arches is tight, and once you’re in, there’s a combination of dark trim and tiny windows to limit joy.

While it won’t matter to many buyers, the front-drive Sealion 8 is rated to tow 1800kg with a braked trailer, and up to two tonnes in the all-wheel drive version. But there’s no spare tyre fitted, and roadside flats need to be addressed by the included tyre repair kit.

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.

We've just spent a week behind the wheel of the Prius c i-Tech; the top model in the two-variant range, sitting above a cheaper model known simply as the Prius c.

At $26,540, it ain't cheap for a city car (and it's $4k more than the most-expensive Yaris on which it is based; more worryingly, it's only $1500 cheaper than an Audi A1), and the standard features list is more a novella than War and Peace.

Outside, you'll find 15-inch alloy wheels, remote unlocking, LED headlights and front fog lamps, while inside you'll leather-look seats (they're actually vinyl), sat-nav and climate-control.

Tech is covered by an  (old-school feeling) 6.1-inch touchscreen that pairs with a six-speaker stereo, but there's no Apple CarPlay or Android Auto.

BYD has managed to keep a lid on the price of the entry-level version of the Sealion 8, by specifying it with front-wheel drive rather than the all-wheel drive of the other two variants. It still gets the same driveline beyond the lack of a driven rear axle, although battery capacity is the other difference.

As such, you’re looking at a 1.5-litre petrol engine (kind of the default powerplant for Chinese SUVs right now) with a turbocharger. With the 19kWh battery chiming in to power the electric motor, the driveline can achieve outputs of 205kW and 315Nm.

In the case of the AWD variants, the larger 35.6kWh battery and extra electric motor ups the potential outputs to 359kW and 675Nm which is a huge jump any way you look at it and gives the Sealion 8 a huge bandwidth when it comes to matching buyer performance aspirations.

All the variants have the potential for a claimed electric-only range of greater than 100km if owners use the plug-in facility to charge either at home or at work. For the AWD variants, the larger battery stretches the EV range to a claimed 152km. On longer journeys or whenever the battery has reached about 25 per cent capacity, the Sealion 8 acts just as any other hybrid with regenerative braking and electric assistance to aid performance.

In suspension terms, the BYD is pretty conventional but if you do pay the extra for the Premium variant, you’ll gain adaptive dampers.

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.

BYD claims a range of more than 1000km for both variants of the Sealion 8, provided you start with a fully charged battery and a full 60-litre fuel tank.

The BYD can also make use of commercial fast-chargers and, when using the maximum 40kW on the FWD version and the 74kW possible for the AWD variant, the charging times from 30 to 80 per cent are both under 20 minutes. The Sealion 8 can also charge at 11kW on an AC socket and the vehicle also offers V2L (Vehicle to Load) capability, meaning it can power on-site work tools, camping gear or even your house at night.

Provided the EV battery is kept at 25 per cent capacity or above, BYD claims a 1.0-litre per 100km fuel consumption figure for the car based on the laboratory test. In the real world, the results will vary enormously depending on where you drive and how the car is used. Deplete the battery and continue to drive at highway speeds, and your actual fuel consumption might easily increase to many times that 1.0-litre claimed figure.

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 first thing you’re going to do in a Sealion 8 is wonder where the gearshift is. It’s a column-shift, but it's not only located where a traditional indicator stalk would be, it looks very much like one, too.

This promises two things. One, you’ll spend a few seconds finding it and two, you’ll try to turn the indicators on with it at least once every drive. (The real indicators are on the other side of the steering column.)

Another note to those test driving a Sealion 8. Sample the front-drive version first. (I’ll get to why in a minute.) When you do, you’ll soon figure out this is a driveline that prioritises electric running. That is, the petrol motor barely ever actually drives the wheels (only at full throttle and higher speeds). Any other time, if the petrol engine is running, it’s to charge the battery that keeps the electric motor purring away. This is how efficiency is defined by BYD.

You’ll also find that the Sealion’s acceleration is purposeful in that electric-motor way, but hardly startling. And when you do smash the throttle and force the petrol engine to drive the axle, you’ll notice that this takes a fair time to play out, and that when everything is grunting as hard as possible, the petrol engine is quite noisy and even a little harsh sounding. Use the driveline sensibly, though, and it’s all smooth and quiet, even if that then means you can hear a little suspension noise creeping into the cabin.

That done, you’re now free to drive the AWD variant. Why wait? Because this thing is seriously off the leash. Bear in mind that 359kW of power is getting on for the thick end of 500 horsepower in the old money, so even though the Sealion 8 is a hefty critter at about 2.5 tonnes, all that power and torque will get it from rest in under five seconds, or thereabouts. The relevance of this to family-car technology is hugely debatable, but it’s one heck of a party trick the first time you try it.

The huge torque also magnifies the Sealion 8’s natural tendency to lift its inside front wheel when accelerating out of a turn. A small tyre squeak can sometimes be heard before the traction control gathers it all together, but even the single-motor variant displays the same trait.

In steering and suspension terms, it’s probably fair to say the Sealion 8 doesn’t unlock any new depths of talent. The ride is pretty comfy but at the expense of body control and the steering points the wheels but doesn’t convey much else to the driver.

That said, the fact everything seems to be tuned to the same frequency means it all works okay. You don’t have too-fast steering fighting the tyres or too firm suspension upsetting the interior calm. Use it as a family would, and it’s 100 per cent fit for purpose.

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.

Every Prius c arrives with seven airbags, along with a reversing camera and... wait, that can't be it, can it? Oh... Forget AEB, lane-departure warning and the like, this future-focused Prius has a safety package firmly rooted in the past.

It was awarded the maximum five-star ANCAP safety rating, but was tested back in 2014.

Servicing any hybrid can be a bit more expensive thanks to the presence of two propulsion forms.

In any case, the Sealion 8 requires routine servicing every 12 months or 20,000km.

Warranty is BYD’s normal six-year/150,000km cover, although there’s also eight years and 160,000km of cover for the EV battery.

BYD also claims its 'Blade' battery technology is among the safest in the business, and says the design resists damage (and, therefore, the risk of fire) better than the competition.

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.
