Denza B8 vs Kia Rio

What's the difference?

The Denza B8 is an incredibly luxurious car that has a lot going for it, including three rows of seating, a 3.5-tonne braked towing capacity and an eye-popping price tag, but it's held back by its overall heft and cumbersome ride.

If you don’t absolutely need the third row of seating, the smaller B5 is arguably the better pick and while it’s also not perfect, it’s a very compelling package and you’ll be saving thousands of dollars in the process.

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

The Rio S Manual is a fun-to-drive little car with a big practicality and multimedia offering in a segment rapidly heading towards extinction.

While some elements of the drive experience are reminiscent of budget cars from 10-20 years ago, Kia makes up for it by wrapping the Rio in a contemporary looking and feeling package, ready for the buyer who needs no frills and demands no nonsense. Until the manual transmission goes the way of the dodo, there is almost no better option.

There’s no way around it, the Denza B8 is a big car. It’s almost 5.2 metres long which makes it larger than a LandCruiser 300 Series and more in line with the likes of the Land Rover Defender 130.

It looks quite boxy and tough on the outside, though it doesn’t have any features that define it specifically as a Denza beyond the inconspicuous badging. There are many angles that are reminiscent of the aforementioned Defender.

The body lines look crisper than the smaller B5, as does the semi closed-off grille and LED light script that connect the big LED headlights.

Unlike the B5, the tailgate-mounted spare wheel is much more prominent in the B8 and this therefore exaggerates its heft, not in a good way.

Inside, it’s luxurious and high-end with lots of visual appeal. I particularly like the amount of soft-touch finishes around the cabin and the overall lack of glossy piano black.

While luxurious, there’s also a rugged edge to the interior. This is most present in the large grab handles which you do need to use when getting in and out.

The amount of physical buttons and switches inside is a nice touch as you don’t need to relate on the touchscreen all the time. The fact the gear shift lever rises up when you turn on the car also adds to the special, luxurious feel.

While notable equipment is missing, the Rio reclaims lost ground with the way it looks, and to a degree, the way it feels.

Ever since this new generation hatch launched, I’ve thought it brings a slick modern design to the city-car space, and even in its most rudimentary form as-tested (our car even came in the most basic ‘Clear White’ paint) it’s a great looking little hatch.

Sure, it doesn’t have the romance factor of the Fiat 500, nor the more delicate curvature of the much more expensive new-generation Toyota Yaris, but it certainly has a more refined visage than, say, the MG3 whilst feeling a bit more grown-up than the Suzuki Swift.

Solid, squared-off lines give this car a sporty pose, and its frowny-face and blocky rear round out a stout city-car persona, and I especially like the way even this most basic trim is adorned with contrast pieces, a spoiler above the boot lid, and body-coloured door handles and mirrors.

Sure, the 15-inch steelies dress it down a bit, but on the Rio these leave the impression of financial prudence rather than cost-cutting.

Inside is basic but tidy. The overall look maintains a hint of sportiness, with an appealing symmetrical finish to the dash.

There’s no question the Rio is a budget model when it comes to the touch though, with everything either a soft polyurethane or a nasty hard plastic, so while it all might look neat it’s far from the most comfortable place to be for long periods of time.

The basic dot-matrix multifunction display, chunky plastic air-conditioning controls, and polyurethane items from the wheel to the handbrake and shifter are reminders of a bygone era, but the overall aesthetic of the driver’s space is pleasing.

Hopping into the B8 you need to acquaint yourself with how the flush door handles operate. Generally they pop open when you unlock the car but sometimes they can be a little delayed.

Also inside the car there are electronic door release buttons which are nowhere near as intuitive as regular door pull handles. Sure you’d likely get used to this over time but you’ll need to explain it to new passengers all the time.

The seats in Chinese cars usually look nice but aren’t that comfortable or supportive for long-distance journeys. The B8’s are the opposite, offering great support and almost limitless adjustability. Adding to this is the standard heating, ventilation and massage functions.

Ahead of the driver is a leather-wrapped steering wheel which feels nice and has plenty of physical buttons with a tactile click when pressed.

Behind this, the digital instrument cluster is clear and high-resolution and offers a number of different layouts and informative pages you can cycle through. This allows you to customise the display.

In the centre of the dashboard is the mammoth 17.3-inch touchscreen multimedia system which is the largest central screen I have seen in a car to date. It’s a big screen for a big car and Apple CarPlay satisfyingly takes up the entire screen.

Thankfully, the screen is snappy and has a native user interface that is easy to navigate around without getting lost. I particularly like the swipe-down control centre menu that allows you to change key settings without diving into sub-menus.

My only hassle with the screen is I struggle to reach the far left-hand side due to its overall size. Perhaps a trackpad would solve this.

As I noted previously, the amount of physical switchgear around the cabin makes adjusting key functions easy. Examples include physical buttons to change the drive mode, activate the surround-view camera, adjust the suspension position and switch between EV and hybrid driving.

In terms of storage up front there are two non-ventilated 50W wireless phone chargers, two cupholders with adjustable depths, a shallow storage section under the centre console, plus a fridge/hotbox under the centre armrest.

Moving to the second row and the luxury continues. The seven-seat model features a three-seat bench that three people can easily fit across as the floor is flat, whereas the six-seat model gets uber-plush captain’s chairs.

Regardless of variant, there’s plenty of room in the second row, even for adults.

Second-row amenities include a small screen on the back of the centre console box that allows you to change the climate control and change the seat heating/ventilation, among other functions.

There’s also a button that opens the fridge/coolbox so the second-row passengers can access it. This is a nifty touch though you’d want to make sure small fingers don’t get caught as the anti-pinch function isn’t the strongest.

A feature that’s unique to the six-seat version is a massaging function on the second-row captain’s chairs. This is a very cool touch that no other SUV at this price point offers.

Accessing the third row in the six-seat version is rather easy as you only need to walk down between the captain’s chairs. It’s also simple enough in the seven-seat version as long as you access it from the kerb side.

Third-row space is decent for adults, but this shouldn’t be surprising as the B8 is such a hulking vehicle. The backrests also recline allowing for extra comfort. Amenities include air vents in the headliner, USB-C ports and scattered storage. It’s enough for seats that will likely only get occasional use.

Around the back the B8 has a side-hinged tailgate which is a little problematic as you need to allow space for it to open up in parking spaces. This is hard when the car is already 5.2m long…

With all three rows upright there is 147L of boot space, which is fine, but this expands to a much more usable 920L with the third row folded.

The boot space is square and usable, though there is a large load lip which is body-coloured and would easily get scratched if you drop something on it. Not the best in a family-oriented vehicle.

Boot-related amenities include buttons to electronically fold the second and third row seats and lower the suspension to make things easier to load into the boot, a 12V socket, scattered hooks, as well as a small underfloor section to store the changing cables.

Although it stands out like a sore thumb, it’s great to have a full-size spare wheel on the back of the tailgate. This is very helpful in the unlikely and unfortunate event you get a puncture.

I'd argue the key reason to buy the Rio at this end of the market is that it has the most space and largest cabin relative to its rivals, bar maybe the Suzuki Baleno.

All-round practicality is great, with front passengers scoring a low, sporty seating position with a high roof, and so much width in the cabin it almost feels like the Rio belongs in the next segment up.

Storage options up front include a large bottle holder and bin in each of the doors, dual cupholders next to the handbrake up front, and a large storage tray underneath the climate unit. Unlike the Yaris or Mazda2, the Rio features a small armrest console box, which gives a small lift to the ambiance of the cabin.

Back seat passengers are treated to great space for this segment, which feels nice and open courtesy of the large rear windows. At 182cm tall, I have airspace for my knees behind my own driving position, as well as relatively healthy headroom and ample width, which is again more like a car in the next segment up.

Rear passengers don’t get adjustable air vents, but there is a single USB port, a single pocket on the back of the passenger seat, and small bottle holders in each of the doors.

Perhaps the Rio’s biggest drawcard is its boot capacity, which at 325 litres is one of the largest in the city car class. Unlike the Yaris, Mazda2, or Suzuki Swift, the Rio will actually accept the CarsGuide three-piece luggage set with the rear seats up, although the rear view was obscured by the medium case.

Thanks to the boxy roofline, the Rio offers a cavernous 980L with the rear seats folded down, and despite its abundance of room, maintains a space saver spare wheel under the floor.

Value seems less important here when you’re contending with a limited list of potential options at this end of the market.

The Rio S manual currently wears an MSRP of $19,690, and if you’re able to shuffle cogs yourself, it counts its rivals as the Suzuki Baleno GL ($18,490), Suzuki Ignis GL ($19,490), or Fiat 500 Lounge ($19,550).

There’s also the option of the MG3 (from $18,990) or Kia’s own much smaller Picanto (from $15,990).

I’m pleased to report the Rio S is one of the best among these options, though. Not only is this car much more modern in terms of its platform and design than pretty much anything on that list, it packs great standard equipment, too.

The major wow-factor item is the Rio’s best-in-class multimedia system, consisting of an 8.0-inch touchscreen with wireless Apple CarPlay and Android Auto connectivity, just one of the areas where this car will grab eyes over rivals.

Elsewhere is a predictably honest list of standard equipment, including basic halogen headlights, 15-inch steel wheels, manual air conditioning, cloth seat trim with a polyurethane steering wheel, a small multifunction display in the dash, two USB ports, a six-speaker audio system, and surprisingly, steering-wheel mounted controls.

There’s no keyless entry or push-start ignition, and this level of equipment makes you feel lucky to have automatic headlights. Sadly, the S manual also misses out on the basic luxury of cruise control.

It’s cheap, missing a lot of gear, and feels it with an abundance of plastic trims, but somehow this car gets by with almost everything you really, truly need. Sure, it’s a bit of a hark back to the equipment lists of the early 2000s, but if you’re just looking for a basic car to get the job done, you could do far worse than this Kia with its impressive multimedia offering.

Power comes from a plug-in hybrid set-up combining dual electric motors and a 2.0-litre turbo-petrol four-cylinder engine.

Total system outputs are a meaty 425kW and 760Nm. They need to be, as the B8 has a kerb weight of 3.3 tonnes. Despite this, Denza claims it can still do the 0-100km/h sprint in just 4.8 seconds.

Power is sent to all four wheels with a rear mechanical diff lock as standard across the line-up. A front diff lock is only offered on the six-seat version.

What’s most surprising about this big beast is it offers a segment-meeting 3500kg braked towing capacity. It also has up to 700kg of payload, depending on the variant.

The Rio is beginning to fall behind here with an antiquated 1.4-litre four-cylinder non-turbo petrol engine. Peak outputs aren’t far off where they should be for this segment, with 74kW of power and 133Nm of torque, although they arrive at the most distant end of the rpm range (6000rpm and 4000rpm respectively) so you need to rev it.

It can be clumsy to extract this power, too, with the engine paired in this circumstance to a six-speed manual which leaves a lot to be desired in terms of action and clutch feel.

While the abundance of ratios can be beneficial for fuel consumption, it’s clear this car was designed to be paired with the more modern three-cylinder turbocharged engine only available on the top GT-Line trim.

Feeding the dual electric motors is a 36.8kWh lithium iron phosphate (LFP) battery. Denza claims it allows for an electric range of 115km, according to NEDC testing.

The battery can also be used as a power source for appliances using vehicle-to-load (V2L) functionality at rates up to 6.6kW.

AC charging is offered at rates up to 11kW, whereas DC fast-charging is offered at rates up to 120kW.

Additionally, there’s a 91L fuel tank. Denza claims this allows the B8 to have a total range of 1040km (NEDC).

Fuel consumption depends on how often you charge the battery. Denza claims the B8 will use 2.0L/100km from 100 to 25 per cent battery charge and 9.9L/100km under 25 per cent battery charge, both according to NEDC testing. Regardless, this is better than all similarly sized petrol- or diesel-powered SUVs.

The Rio S manual has an official combined cycle fuel consumption rating of 5.6L/100km, which is about right for a light car with a small engine.

On test, covering largely urban kilometres, I saw a higher but not unreasonable 7.4L/100km. Still, this number isn’t too far off what some larger cars with 2.0-litre engines are capable of.

Rios with this engine accept entry-level 91RON unleaded fuel, and have 45-litre fuel tanks. They are only compliant with Euro 5 emissions regulations.

Behind the wheel, the Denza B8 primarily acts as an electric vehicle (EV), meaning it’s largely quiet inside the cabin when driving around normally.

Once the battery charge gets down lower, the petrol engine typically switches on to top up the battery. It largely acts as a generator and a lot of the time you can’t tell whether it’s on or off.

You’ll likely only notice it if you floor the accelerator or go up a steeper hill. Even then the engine largely stays quiet and in the background.

When the battery charge gets down low enough and you gun it, the petrol engine can directly power the front wheels. This is rare, though, because the car leaves at least 25 per cent battery charge in reserve.

With 425kW and 760Nm thanks to the dual electric motors and 2.0-litre turbo-petrol engine, the B8 is far from slow. In fact, for a 3.3-tonne beast it absolutely hauls thanks to the instantaneous torque the electric motors provide.

However in the standard drive mode there is a noticeable input lag from when you push the accelerator pedal hard and when the car starts accelerating. This is reduced in the 'Sport' drive mode.

Although the B8 may produce lots of power and torque, it feels its weight. When you accelerate hard it pitches back dramatically, much like the Jeep Grand Cherokee. It’s much more pronounced than in the smaller B5, but still smile-inducing.

As standard, the B8 line-up gets an adaptive hydraulic suspension system that is claimed to be able to self-level the car. Despite this, the B8 gets a considerable amount of body roll regardless of which drive mode you select.

Many Chinese cars have floaty, comfort-oriented suspension tunes over firmer and a more dynamic-feeling ride, and the B8 is no exception. It feels like a 3300kg+ SUV.

The kicker is, like many body-on-frame vehicles, the ride gets busy on harsher roads with more frequent bumps. As a passenger you get jostled about in the cabin.

The steering tries to disguise the overall heft of this SUV but as a result it can feel overly assisted and vague at certain points. Depending on the drive it either artificially adds or reduces resistance.

Unlike the related BYD Shark 6, the B8 gets diff locks and a low-range mode which uses a clutch pack on the rear electric motor to allow for more controlled, low-speed crawling.

The adaptive hydraulic suspension allows the car to be lowered down or lifted up. In its highest mode there is a 890mm maximum wading depth.

Interestingly, compared to the smaller B5, the B8 feels more sorted off the beaten path. Its added heft helps round off bumps more easily, plus there’s added momentum behind it.

Lastly, in terms of noise, vibration and harshness (NVH), the B8 is a very quiet car to drive. As I mentioned above, the electric-first nature automatically makes this a quiet car.

Surprisingly, given the B8 is a huge 3.3-tonne box on wheels, there is very little road and wind noise. It seems Denza has put a big emphasis on sound insulation.

A six-speed manual with a tiny non-turbo engine is an absolute oddity in today’s new car market, but as a result of its rudimentary approach, there’s something refreshingly honest about the Rio S.

The engine requires a wringing to extract the desired result, and a lot of action on the gears, as six speeds proves to be quite a few to work your way through before you achieve cruising speed.

As so much interaction is required with the transmission, I wish it was tighter when it comes to the clutch which feels a bit doughy at the best of times.

The Rio is very organic, though, with next to no electrical assistance for any of its interaction points offering the driver a high level of control.

The steering is direct, but as a result of a cheaper rack (with less teeth compared to this car’s Stonic relation), it feels simple and brittle when it comes to feedback.

The same criticism can be levelled at the suspension, which errs on the side of firm. This attribute combines with the low seating position to make even this most basic Rio an absolute hoot in the corners.

But it can be a little crashy over every-day potholes and corrugations, despite the abundant amount of rubber cladding the 15-inch steel wheels.

Visibility is superb out of this little car’s big windows, making you feel in control of your surroundings (necessary in the multi-lane confines and tight parking conditions of a city), and ergonomics in the cabin are absolutely on-point with the large touchscreen elements easy to reach and the instruments taking a basic no-nonsense form.

While noise levels are okay at urban speeds, they pick up above 80km/h, making the Rio more unpleasant to drive over long distances than, say, the more upmarket-feeling Yaris.

The Rio does find its place in this price bracket as a fun-to-drive, but predictably rudimentary experience, for the niche audience of drivers seeking an entry-level car who are still able to shift gears themselves.

Sadly, the Rio S misses out on any advanced active safety items. This is one area where city-sized cars are struggling to keep up, as expensive active safety systems tend to push them well into the mid-$20,000 region.

Unlike the mid-range Rio Sport, the S has no auto emergency braking, lane keep assist, or driver attention alert.

It makes do with the more basic array of brake, stability and traction controls, with the addition of a great reversing camera, three top-tether and two ISOFIX child seat mounting points, and six airbags.

The Rio carries a valid five-star ANCAP safety rating, to an earlier 2017 standard before its missing modern active safety items were mandated.

The Denza B8 is covered by a six-year, 150,000km warranty, whereas the battery pack is covered by an eight-year, 160,000km warranty. There’s also three years of roadside assistance.

This isn’t a standout warranty in the mainstream market, though compared to premium marques it’s a notable step up.

Logbook servicing is required every 12 months or 20,000km, whichever comes first.

The first five years' of servicing totals $3762, which averages out to just over $750 per service. This is just a tad more than the smaller B5, but it’s much cheaper than premium rivals.

The Rio again gets the edge on its budget competition with a lengthy seven-year, unlimited kilometre warranty. In this space it only butts heads with the MG3, which offers a matching promise.

Roadside assist is included for up to eight years if you continue to service with Kia, and there's also a capped price service program for the duration of the warranty, covering up to 105,000km.

The Rio needs to be serviced once every 12 months or 15,000km, and prices range from $269 and $608 per visit, for an annual average of $409.40.

Not the cheapest servicing schedule we’ve seen, particularly when compared with the likes of Toyota.
