Denza B8 vs Peugeot 508

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.

The Peugeot 508 Sportswagon GT PHEV proves wagons can be extremely stylish but looks aren’t everything and it is an expensive option compared to its luxury rivals. It earns its place with the premium interior but the safety could be improved on and the tech is more confusing than it needs to be. But this wagon offers an alternative for families who are sick of being in an SUV yet still need a little extra space. 

My son didn’t go nuts over this and complained about his view.

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.

The design of this wagon is what wins it the most points. It is a damn fine specimen with the sleek lines in the body panelling and the sexy rear that looks well-proportioned for its 4790mm length.

Dark, narrow windows, 18-inch alloy wheels and a minimalist-looking nose, with fang-like daytime-running lights, all enhance its sporty look.

The rear lights have Peugeot’s signature ‘claw’ design and there’s something suggestively fun about seeing a twin-exhaust on a wagon!

On the interior, the multimedia system takes centre stage and the dashboard looks quite sleek, despite all of the deep cutaways.

The steering wheel is in the compact style that Peugeot is known for but it makes the cockpit feel driver orientated.

The quilted Nappa leather trims and shiny piano-black accents (with the piano-key controls) make for a refined cabin space.

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.

The front row gets the most space and you’ll be able to get into a comfortable position even if you’re tall.

However, it is a low car with its 142mm ground clearance and there may be a few grunts as you get in and out (or is it just me?).

My seven-year old loves how easy it is to climb in, though he didn’t have the best view out of the windows because the sills sit high.

The footwell lip also sits quite high, which isn’t an issue until you can’t open your door very wide and then it’s clumsy in a tight parking space.

The electric front seats are very comfortable and the extendable under-thigh support helps to minimise leg fatigue on a longer journey.

Surprisingly, for my 168cm (5'6") height, I have to sit much further back than I ordinarily would to get a comfy driving position.

In the back, you have plenty of headroom but behind my driving position, the legroom could be better.

An adult would still find it fairly comfortable on a longer journey so long as they aren’t behind someone tall. The seats themselves are well-cushioned and you sit in, rather than on top of them.

Individual storage options are good for this class with a dual-opening middle console, glove box and a great utility cubby next to the transmission shifter.

There is also a shelf underneath the centre console that houses the wireless charging pad and two USB-A ports but it’s a tad awkward to use and even see the ports when you're seated.

The amenities are good in the rear but for a top-spec model it’s lacking the luxury items you might expect, like heated seats and climate control but you’ll enjoy map pockets, reading lights, two USB-A ports and directional air vents.

It also has a fold-down armrest with two shallow cupholders, that in a quick turn, might spill their cups!

The boot is a great size at 530L with all seats in use and you can bump it to 1780L with the rear seats folded.

You get a level loading space and a 60/40 split with a ski-port in the back seat, which opens up your storage options.

There is a tyre repair kit rather than a physical spare but the tailgate is powered, which I always like.  

The technology is a mixed bag. It looks sharp and the touchscreen multimedia system is responsive but isn’t as easy to use as others I’ve sampled.

It doesn’t have a lot of accessible information or customisations available but it is easy to connect to the wired Apple CarPlay. There is also wired Android Auto for those users and built-in satellite navigation. 

The 12.3-inch digital instrument panel is the prettiest piece of tech in the car and there is more customisation available to make it feel yours.

Considering its price point and top-model status, it's more obvious that you miss out on premium items like three-zone climate control, faster USB-C connections and a head-up display.

Keeping things simple, there are only two variants for the 508 Sportswagon and our test vehicle is the top GT plug-in hybrid model that will cost $82,915 before on road costs.

That’s a $1000 price hike from last year and sets it well above its rivals with the Audi A4 coming closest at $78,169 (MSRP).

Given its rivals are well known for their luxury, the 508 has a fair bit to live up to but its styling and use of premium materials, like the quilted Nappa-leather trims, help it earn its position within the ranks.

The interior gets some other lovely big-ticket items with the eight-way electric front seats and a two-way memory position function on the driver’s seat.

Both front seats feature a heat function, adjustable lumbar support and a fabulous massage function. The ‘Cat Paw’ option is particularly nice!

However, the back seat misses out on these ‘top-end’ creature comforts.

There is a sunroof optioned on our test vehicle which adds $2500 to the price tag but creates an airy cabin in what would ordinarily be a bat-cave-esque space with that black headliner.

Only one colour is included in the price and our ‘Pearl White’ costs an extra $1050.

Technology has been revitalised with a new 10-inch touchscreen multimedia system and a 12.3-inch digital instrument cluster.

Dual-zone climate control, push-button start, keyless entry and a powered tailgate all add some practicality to every day life, too.

Phone mirroring tech like wired Apple CarPlay and Android Auto are easy to connect to and there are a bunch of charging options available throughout the car, including a wireless charging pad up front.

All-in-all, though, the features list isn’t as long as the price point might suggest.

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 GT plug-in hybrid model has a 1.6-litre, four-cylinder turbo-petrol engine, as well as an electric motor that sits on the front axle. It has an eight-speed automatic transmission that produces smooth gear changing driving the front wheels.

The combined outputs are 165kW and 360Nm which means you have a good amount of power for this sized car but it’s not a performance wagon as its 0-100km/h sprint time is 8.3 seconds.

The lithium-ion battery has a small 11.8kWh capacity and will get from 0-100 per cent in three and a half hours on an 11kW system. On my standard house plug, it took closer to six and a half hours.

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.

Peugeot says you can travel up to 55km on pure electric function, however my morning (return) school run is 38.4km and the electric range was spent by the time I parked in my garage after starting on a full charge. 

Under optimal conditions, where you’re utilising both the engine and motor, the GT PHEV has an official fuel cycle consumption of 1.5L/100km.

After charging it three times, travelling 444km on a mix of open/urban roads and using 33 litres of fuel, my real-world usage came to 7.4L/100km.

You absolutely get the best economy when you regularly charge it but sometimes you just don’t get the time to!

You'll need 43 litres of premium 95 RON unleaded fuel to fill the tank which, using our real-world average consumption figure, translates to a driving range of around 580km.

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.

The 508 Sportswagon is an odd car to drive. Around the city, the steering makes it feel like you’re in a go-kart and you may over-correct until you get used to it. 

On the open-road, it feels like it gets into its groove but the power reserves feel a tad too shallow as the engine can complain with only a light load. 

The suspension is well padded and you won’t notice too many bumps but you do get a fair bit of wind and road feedback at higher speeds. 

Because of the narrow windows, I am surprised by how great the visibility is but you feel tiny when you sit next to a big SUV in traffic!

That said, it corners beautifully and taking this on a winding coastal road is super fun.

The brakes are very responsive, which is great in stop-start city traffic but can make it feel a little jerky while navigating a car park.

And on that note, because of the funky steering feel, it takes a moment to calibrate your senses with what the car is doing.

Once you get used to it, it’s simple to park but the quality of the 180-degree camera system is pretty rubbish for where this car sits in the market.

The 508 has most but not all of the safety features you expect to see in a family car.

The active bonnet is a great feature as it lifts up in a collision to help minimise pedestrian injuries. 

However, in the modern market and this being a top-spec model, I am surprised it's lacking a few safety features, namely rear cross-traffic alert.

Other standard safety equipment includes blind-spot monitoring, LED daytime running lights, forward collision warning, lane keeping aid, lane departure warning, intelligent seat belt reminders, front and rear parking sensors, a 180-degree view reversing camera, traffic sign recognition, a driver attention monitor, and adaptive cruise control with stop and go functionality.

The 508 has a maximum five-star ANCAP safety rating from testing done way back in 2018 and it only sports six airbags, which is low for a family vehicle.

The 508 has autonomous emergency braking with car, pedestrian and cyclist detection and is operational from 10.0– 80km/h (5.0 – 140km/h for car).

There are ISOFIX child seat mounts on the outboard rear seat positions and three top tethers in the second row but two child seats will fit best. Front passenger comfort may be compromised when a 0-4 rearward facing child seat is installed.

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.

On the 508 you’ll enjoy a five-year/unlimited km warranty and the battery is covered by an eight-year or up to 160,000km warranty, which is great.

You can pre-purchase either a three- or five-year servicing plan and the five-year plan costs a flat $2100 or an average of $420 per service which is very reasonable for this class. 

Servicing intervals are at every 12months or 20,000km, whichever occurs first.
