Denza B5 vs Volvo C40

What's the difference?

Denza has made a huge statement with the B5 and for the most part the hype is deserved. It packs an incredible amount of luxury and tech inside and out which is even more surprising given the impressive asking price.

There are only a few flaws like the busy ride, over-the-top body roll and the occasional infotainment quirk. Hopefully these can be fixed with future over-the-air software updates.

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

The C40 becomes a compelling option in the electrified small SUV space, offering a premium look and feel, great range and tech inclusions at the price, as well as awesome on-road dynamics.

Its main downsides are the rear seat, which is compromised by its platform and design-led roofline, and the overwhelming power and added traction of the dual-motor makes the single motor less attractive on the value front.

Still, regardless of variant chosen, the C40 looks to offer a stand-out balance of price, range, and performance, against its traditional rivals and newcomers alike.

It’s worth calling out straight away that the Denza B5 is essentially an SUV version of the BYD Shark 6 as the two share underpinnings, but it’s much more luxurious and blingy.

Externally it has a big, boxy and bluff design that helps it stand out on the road. It looks even tougher when the suspension is in its lifted mode.

I particularly like the front fascia with the big headlights and the prominent Denza badge on the grille, but there are some strange body creases around the side.

While the boxy looks make the B5 stand out, it’s not necessarily unique. There are elements that are reminiscent of the Land Rover Defender, plus many angles look similar to the GWM Tank 300.

Inside is where the luxe is dialled to the max. There are so many soft touches around the cabin that it makes a lovely place to spend time.

Additionally there is a lot of high-quality physical switchgear which is surprising given how prominent the large 15.6-inch central touchscreen is.

Lastly, I like how substantial many of the finishes are. There are large grab handles on either side of the dashboard which you do need to use to hoist yourself into the cabin, plus chunky interior door handle pulls that are satisfying to use.

Volvo has become a brand with a distinctive and consistent design language which embodies the kind of beautiful minimalism normally associated with Scandinavian brands.

I have always liked how Volvo says more with less design elements, with only gentle touches of chrome or gloss black, and a lack of over-the-top sporty pieces avoiding the temptation to over-sell the sporty potential of the brand’s range.

The C40 takes the small SUV formula, well established by its XC40 relation, and gets a bit weird and experimental. It’s slightly lower and has a more coupe-styled rear, with a strongly raked rear window giving it a sportier and more aggressive look than the rest of Volvo’s SUV range.

The styling is sold by an angular spoiler piece running atop the boot, and the rear light clusters have gone all minimalist, constructed of individual pieces rather than a single transparent housing, and they give a nod to the C30 hatchback which this car is the spiritual successor to, by name and nature.

The interior offers up no surprises, sticking to the formula Volvo has established across all of its current models. An effortlessly premium space with, again, a minimalistic dash dominated by the portrait touchscreen, the C40’s premium nature is confirmed by its finely patterned inlays, simple chrome pieces, and abundance of soft-touch surfaces.

The big upright vent fittings with clever rhomboid patterns on their adjustment dials are always a highlight piece of modern Volvos, and the pattern work is continued on the central volume adjust dial and even on the little rotating pieces of the light and wiper stalks. Clever.

Even the software is paired back on the multimedia suite and digital dashboard, with easy to use shortcuts and simple menus which suit the car.

Volvo might turn off some buyers with the more unconventional shape of the C40. But for those looking for a more traditional SUV it also offers the XC40 in the same two variants, and the Polestar 2 caters to those not looking for an SUV at all.

Many Chinese cars have lots of bling but lack actual substance when it comes to comfort and usability. This is where the Denza differs.

Take the driver’s seat, for example. In a number of Chinese cars they look plush and comfy, but in reality they are firm after longer drives and lack adjustability.

The B5’s driver’s seat, however, is very comfortable, offering almost limitless adjustment, plus heating, ventilation and even a massage function as standard. The latter is great for longer road trips.

Ahead of the driver the steering wheel has plenty of adjustment, allowing people of different heights and statures to get comfortable behind the wheel. There are also lots of physical buttons and switches that have a satisfying click when pressed.

The digital instrument cluster is high-resolution and clear, and there's a number of different informative pages that you can cycle through. It’s nice to have this level of customisation.

Moving across, the aforementioned 15.6-inch touchscreen multimedia system dominates the dashboard. If you’re familiar with the user interface in other BYD vehicles, it’s virtually identical in the B5.

It’s very easy to navigate around and if you do get lost there are a number of shortcut buttons at the bottom of the screen that can either take you back home or to other key functions.

One of my favourite features about the screen is the swipe-down control centre menu. You can customise it to have key shortcut functions. It’s much better than having to dig through countless submenus.

It’s clear Denza still has a few kinks to iron out with the translations from Chinese to English as some don’t make sense. Denza will likely sort this with future software updates.

As standard there is wireless Apple CarPlay and Android Auto and it takes up the full screen when connected. It’s a stunning set-up, though reaching the far left-hand side of the screen from the driver’s seat can be a little tricky on the move.

As I touched on earlier, there is a lot of physical switchgear around the cabin which is helpful as you don’t need to solely rely on the touchscreen for key functions. The piano key buttons for the drive and EV/HEV modes are particularly handy, plus the rising gear shift lever is premium-feeling.

In terms of storage up front, there are up to two 50W wireless chargers (depending on the variant you opt for) with ventilation, two cupholders with adjustable depths, some shallow storage under the centre console, plus a fridge/hotbox under the centre armrest.

Moving to the second row there is plenty of space for at least two adults to sit comfortably. Pushing it to three may be a little tight with shoulder room, plus the centre seat is raised compared to the outboard ones. It’s worth noting though that there is a flat floor so you don’t need to fight for foot space.

Second-row amenities include chunky grab handles for easy ingress and egress, air vents on the back of the centre console, as well as heated and ventilated outboard seats in the top-spec Leopard trim. It’s properly luxe.

At the back the tailgate is side-hinged which can be problematic if you reverse into a carpark as you need to allow for space for it to open up. It has a soft-close function which is handy as you don’t need to slam it shut.

There’s 470L of boot space with the rear seats upright, expanding to around 1000L when folded. It’s a decent amount of space and is square with a very minimal load lip.

Amenities include a 12V socket, a wide array of hooks and nets, as well as a small storage space under the boot floor for the charging cables.

Lastly the B5 comes with a full-size spare wheel mounted on the tailgate. This is becoming increasingly rare in electrified vehicles and is very handy if you have a puncture.

The C40 is essentially a XC40 with a cropped down roofline, and there are some obvious downsides which this new shape brings.

The front seat throws no surprises, though, offering plenty of room for two adults with a welcome level of adjustability for the seat and wheel. The seats could be more comfortable, though, with a notable lack of padding in the base compared to some luxury (or even non-luxury) rivals. 

I’m a fan of the fabric trim which comes on both grades, bucking the trend of needing to have leather or leather-like trim for a car to feel ‘premium’.

The ample window space up front, including the massive glass roof helps the C40’s cabin feel spacious, but the view out the rear with its aggressive design is all but a very limited letterbox aspect, particularly if the rear seat headrests are in the upright position. 

While some controls are exclusively via touch interface, there is a physical volume dial, and shortcut buttons for the defogger functions. 

Temperature is controlled by touch, however, and the detail settings have some smaller toggle adjustments. Tricky to jab at when you’re on the move.

The digital dash is refreshingly simple, but minimally adjustable, with the choice of either a nifty navigation screen, a blank screen, or trip details being the only options.

Cabin storage is good but not stellar. There are bottle holders and big pockets in the doors, a set of two cupholders in the centre (beats the Polestar 2’s single cupholder), a small tray with a wireless charger under the multimedia screen, and a smallish console armrest box.

The rear seat is where the real problem exists. Unlike the XC40, the C40’s cropped roofline means my head was hard up against the roof (I’m 182cm tall). 

I did have decent knee room behind my own seating position, however the seat comfort in the back still isn’t as good as some rivals. 

The middle position is also compromised, thanks to the raised centre floor piece the C40’s platform needs to facilitate all-wheel drive in its combustion relations.

A bottle holder appears in each door pocket, and in a rare inclusion, there are heated outboard rear seats, adjustable air vents, and USB-C charging ports.

The boot has a quoted capacity of 413 litres with the rear seats up. The floor is comparatively high suggesting a smallish space when loaded with luggage cases, for instance. Stay tuned for a follow-up review so we can see how well it holds our three-piece demo set.

The floor itself has an adjustable, pop-up divider and multiple luggage hooks, making it quite versatile, and there is a cavity beneath which can hold your charging cables as well as the inflator kit in place of a spare wheel.

When it comes to electric vehicles, it’s impossible to consider price alone, as you also have to consider driving range, and the C40 manages to impress on both fronts.

Its refreshingly simplified range consists of just two highly-specified variants, a single motor which starts from $74,990, offering a 434km driving range, or a dual motor starting from $82,490 which offers a 420km driving range.

There’s much more devil in the detail, but to set the scene there are now quite a few direct rivals in this price-bracket, including everything from the Tesla Model Y (from $72,300), Mercedes-Benz EQA (from $78,513), Polestar 2 (from $63,900) and even the Kia Niro which is similarly sized and specified (from $65,300).

Interestingly, the C40 is closely related to the Polestar 2, but has a much higher base starting price. Volvo says this is because it carries a higher standard specification, and offers the C40 without option packs.

Standard gear on the base single motor C40 includes 19-inch alloy wheels, a 9.0-inch portrait multimedia touchscreen (running a Google-based always-online software suite), LED headlights, dual-zone climate control, a fixed panoramic sunroof, electrically adjustable front seats, heated seats for the front two and outboard rear seats, a powered tailgate, as well as keyless entry with touch-free ignition.

Interestingly, Volvo also told us some 90 per cent of customer interest so far has been for the more expensive dual-motor variant, which is particularly impressive for doubling the power output while adding 20-inch alloy wheels, a 360-degree parking suite, premium Harmon Kardon audio, and an alternate interior trim.

Both variants score safety equipment and items which are otherwise part of expensive option packs in the Polestar 2 range. We’ll take a look at the full safety gear later in this review.

Overall, the C40 impresses on the premium car value front compared to rivals, bolstered by solid range and impressive performance.

Power comes from plug-in hybrid set-up combining dual electric motors (one on each axle) and a 1.5-litre turbocharged four-cylinder petrol engine.

It’s a similar set-up to the BYD Shark 6, but the B5 has more power. Total system outputs are a meaty 400kW and 760Nm, which is good for a claimed 0-100km/h sprint in just 4.8 seconds.

Power is sent to all four wheels and for added peace of mind off-road there are front and rear mechanical diff locks as standard, plus a wide range of drive and terrain modes, including a low-range mode.

Backing this up is a 3000kg braked towing capacity and up to 600kg of payload.

Great news here, the C40 can be chosen with two powerful layouts, either a front-wheel drive 170kW/330Nm set-up, or a dual-motor all-wheel drive arrangement, able to make use of nearly double the power at 300kW/660Nm. The dual-motor is capable of sprinting from 0-100km/h in just 4.7 seconds.

The front-drive is backed by a 69kWh battery allowing it a 434km range, while the dual motor ups the battery size to 78kWh to allow a 420km driving range.

Feeding the electric motors is a 31.8kWh lithium iron phosphate (LFP) Blade battery which Denza claims to allow the B5 to travel up to 100km on electric power alone, according to NEDC testing.

There’s also vehicle-to-load (V2L) capability with 6.6kW output through the charging port using an adapter. This allows you to use the battery charge to power appliances. It’s handy if you go camping, for example.

The battery can be AC charged at rates up to 11kW or DC fast-charged at rates up to 100kW.

There’s also an 83L fuel tank. Denza claims the B5 has a total range of 975km, according to NEDC testing.

Fuel consumption depends on whether or not you charge up the battery. Denza claims you’ll use 1.9L/100km from 100 to 25 per cent battery charge and 9.5L/100km under 25 per cent battery charge, both according to NEDC testing. Regardless, this is better than similarly sized diesel-powered SUVs.

Surprisingly, energy consumption is quite high for both C40 variants. The single motor is the more efficient of the two, consuming 16.8kWh/100km on the more lenient ADR testing schedule, while the dual motor officially consumes 22.2kWh/100km to the same standard. I saw around 23kWh/100km overall in my short test of the dual-motor variant.

Energy consumption could be better for both, as I have achieved more consistently impressive results particularly from Hyundai and Kia electric cars.

Where the C40 is more impressive though is its charging specs, which are exactly where they need to be for a car this size. On a rapid DC charger, the C40 can charge at a rate of 150kW meaning a 10 - 80 percent charge in 40 minutes for the dual motor, or 32 minutes for the single motor.

On the slower AC standard, the C40 charges at a rate of 11kW. Expect a 10 - 80 percent charge time of around five or six hours on this standard. 

The C40 uses a European-standard Type 2 CCS charging port, although it misses out on the handy two-way charging feature offered by some rivals.

Behind the wheel the Denza B5 primarily operates as an electric vehicle (EV) first up, meaning it’s largely quiet inside the cabin when driving around normally.

Once the charge starts to drop, 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 actually tell whether it’s on or off.

In some cases where you floor the throttle or go up a steep hill, the engine revs can flare and that’s when it makes its presence known in the cabin.

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 purposefully leaves at least 25 per cent battery charge in reserve.

With 400kW and 760Nm thanks to the combination of the dual electric motors and the 1.5-litre turbo-petrol engine, the B5 absolutely hauls. The peppy feel is largely due 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 a bit harder and when the car actually accelerates. This is reduced in the sport drive mode.

Despite the juicy outputs, the B5 does feel its weight. When you accelerate hard it pitches back extensively, much like the Jeep Grand Cherokee Trackhawk. This never failed to make me smile though.

It’s surprising as we only drove the top-spec B5 Leopard on this launch and it comes fitted with the DiSus-P adaptive hydraulic suspension system which has a self-levelling function.

In the bends the B5 gets a considerable amount of body roll regardless of the drive mode. This is common for many Chinese cars as they typically prioritise floaty comfort-oriented tunes over a firmer and more dynamic-feeling ride.

Despite this, once it leans over it’ll comfortably hold and grip, largely thanks to the chunky 275/55 R20 Pirelli Scorpion tyres that come standard on the top-spec Leopard trim.

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

The steering, while direct enough, can have a vague and artificial feeling. Depending on the drive mode it either artificially adds or reduces the resistance.

Unlike the related BYD Shark 6, the B5 gets a low-range mode which uses a clutch pack on the rear electric motor to allow for more controlled low-speed crawling, plus front and rear mechanical diff locks. This can make a big difference once the going gets really tough.

Additionally, the DiSus-P hydraulic suspension allows for a total of 140mm of travel. In the highest position there’s a wading depth of up to 790mm.

Lastly in terms of noise, vibration and harshness (NVH), the B5 is a very quiet car to drive. As I mentioned above, the electric-first nature automatically makes this a quiet car.

There is very little road and wind noise. This is surprising as the B5 is essentially a 3.0-tonne box on wheels. It seems Denza has put a lot of effort into sound insulation.

If you’ve driven any kind of XC40 or even a Polestar 2 before, the C40 will offer no surprises. It’s pretty much exactly the same from behind the wheel with a few subtle tweaks.

This is a very good thing. The C40 is quiet, easy to drive, and its electric motor and regen system offer a smooth single-pedal experience.

It is also alarmingly, overwhelmingly, rapid. While its massive set of batteries under the floor make it feel heavy off the line in stop-start traffic, sticking your boot into the accelerator will remove any doubt, particularly in the dual-motor variant, that this Volvo means business.

The dual-motor also has an incredible torque-vectoring system, making it extremely difficult to elicit so much as a squeak from its tyres. It also feels as though torque is distributed quite evenly between its two driven axles, making it feel neither prone to over- or understeer.

This has the effect of making the C40 feel somewhat indestructible in the corners, with absurd levels of grip. 

The same feeling is present in top-spec versions of the Polestar 2, only the feeling of ever-present weight is more noticeable in the higher-riding C40, which can make it unsettling to take corners at the kinds of speeds it is capable of.

The steering tune is interesting. Volvo offers two software-controlled modes, either heavy or standard, and the standard mode is heavy enough. 

Despite its electrical assistance, the wheel does continue to offer some organic feedback, making the C40 a pleasure to steer on countryside roads.

The ride is also surprisingly good, despite massive wheel options. I was impressed how easily the C40 handled most bumps and undulations, communicating little to the cabin. 

The ride can approach its limits with such big wheels and the weight of its batteries, generally these are communicated via unsettling thuds from underneath the car. Regular undulations at higher speeds also had the C40 bouncing around a little.

On the whole, though, the cabin is kept relatively insulated and serene, adding an element of total confidence, similar to that offered by Teslas, whilst offering better ride quality with a softer edge. At higher speed, at least on the 20-inch wheels, road noise does pick up, however.

In terms of electric driving, there is a single adjustable setting for regen. The car either offers a full single pedal mode with maximum regenerative braking to bring the car to a halt with the motor alone, or a ‘standard’ mode which tones the regen down and offers it blended in via the brake pedal. 

Single pedal mode is more efficient. I suggest you stick to it if you want to make the most of this car’s efficiency.

I was surprised to have so few complaints about the C40’s drive experience. This is a balanced and capable EV which is yet another example of how even vehicles which use combustion platforms are improved out of sight by full electrification.

Sticking to its brand promise, Volvo offers the full range of active safety equipment on the C40 regardless of variant.

This includes freeway-speed auto emergency braking, rear auto braking, lane keep assist with lane departure warning, blind spot monitoring with rear cross-traffic alert, and one of the best adaptive cruise control systems on the market.

The only item the single motor misses out on is a 360-degree parking camera, which is exclusive to the dual motor variant.

It is notable how the adaptive cruise control, blind spot monitoring rear cross-traffic alert, and rear auto braking are on the options list for the Polestar 2.

These active systems combined with eight airbags (the standard dual front, side, and curtain, as well as a driver’s knee and centre airbag) make for a five-star ANCAP safety rating to the latest 2022 standards.

Denza B5 owners are covered by a six-year, 150,000km warranty, whereas the high-voltage battery is covered for eight years or 160,000km. Owners also receive three years of roadside assistance.

This warranty length is fairly standard in the mainstream segment, but in the luxury segment it pushes past the current five-year benchmark.

Logbook servicing is required every 12 months or 20,000km, whichever comes first. The first five years of servicing totals $3542, which averages out to just over $700 per service. This does seem like a lot, but in the premium space this is rather competitive, especially once you consider both the electric and combustion components are being serviced.

There are currently seven Denza dealers around Australia and it plans to have a total of 20 by the end of 2026. It’s also planning to allow certain BYD dealers to service Denza cars.

The C40 is covered by Volvo’s five year and unlimited kilometre warranty, with a separate eight-year, 160,000km warranty for the battery. There is also eight years of roadside assistance attached.

It is pleasing to see the service intervals for the C40 are long, as they should be for an electric car with so few moving parts, set at two years or 30,000km. 

The first 24 month service is free of charge, and Volvo tells us service pricing after this period will average out to around $100 a year ($200 per visit).
