Aston Martin Vanquish vs Denza B5

What's the difference?

The definition of luxury is having something you want, rather than something you need. And the Vanquish is definitely something you don’t need, but will desperately want once you’ve experienced it. It’s opulence on wheels, the kind of car you buy mostly because you can. Because owning a V8-powered Aston Martin wouldn’t cut it in your circle of friends. Or because you just want the very best things in life, cost be damned.

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.

While the engine is the unique heart of the Vanquish, the design is the first element that grabs your attention. Even for a brand renowned for its GT cars with imposingly long bonnets, the Vanquish stands out.

That’s because the designers deliberately added 80mm of space between the front axle and the A-pillar (the front windscreen pillar) to elongate the bonnet even more for what it calls a “rakish and indulgent” profile. 

The lines flow across the length of the Vanquish, from its trademark grille to its Kamm Tail, giving it a look that is somehow simultaneously classically Aston Martin - with elements of its multiple generations of GT cars - while also being contemporary. 

Some of the modern touches are derived from Formula One, as the brand looks to leverage its racing team, with bonnet louvres to help cool the engine without unsettling the air-flow too much.

Aston Martin’s Chief Creative Officer Marek Reichman calls the Vanquish “an iconic halo model” and explained the design was deliberately pushing “beyond the expected, rational, and thoughtful.” Which sums up this dramatic piece of automotive art quite nicely.

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.

Despite measuring nearly five metres long, the Vanquish is a surprisingly small car from a practicality perspective. Because the added wheelbase is ahead of the cabin, it remains strictly a two-seater, with no room for rear passengers.

There’s limited small item storage, too, aside from a couple of cupholders and a lidded console box. Although, on the plus side, the lack of rear seats creates room for some small shelves in case you need to store some loose items.  

It also has a surprisingly small 248-litre boot, which means limited storage for anything, including luggage, for a road trip in what would otherwise be a great road trip car.

As for the multimedia system, while not at the cutting edge (although Aston Martin will debut Apple CarPlay Ultra in its DBX model) the system works well for this type of car.

It’s unlikely too many under 25s will be grabbing this $700K luxury GT, so the fact the media system has a touchscreen and an array of physical buttons is a welcome detail.

As for the 1170-watt, 15-speaker Bowers & Wilkins sound system, it performs incredibly well, as you would probably expect. Like the car it has loads of power but excellent attention-to-detail with fantastic clarity, too.

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 2026 Denza B5 is offered in two trim levels – entry-level and the top-spec Leopard. Pricing for the former is $74,990 before on-road costs, while the latter is $79,990 before on-road costs.

This is very competitive and it undercuts many top-selling rivals like the diesel-powered Toyota Prado and Ford Everest by a significant margin if you want similar levels of specification.

It’s worth noting however, the GWM Tank 300 PHEV, which is the B5’s closest rival in terms of powertrains, is even cheaper at $59,990 drive-away.

As a base, the B5 is loaded with standard equipment. You get 18-inch alloy wheels, adaptive LED headlights, a glass panoramic sunroof, 12.3-inch digital instrument cluster, 15.6-inch touchscreen multimedia system, 16-speaker Devialet sound system, leather upholstery, heated and ventilated front seats with a massage function, plus heated outboard rear seats.

If this isn’t enough, the B5 Leopard gets larger 20-inch alloy wheels, adaptive hydraulic suspension, a digital rear-view mirror, a second wireless phone charger, Nappa leather upholstery and ventilated outboard rear seats.

This amount of standard equipment is wild, especially because the asking price is firmly below $100K.

The engine is undoubtedly the star attraction of the Vanquish, with the twin-turbo 5.2-litre V12 being the last of its kind in the British brand’s line-up now that the DB12 has switched to an AMG-sourced twin-turbo V8. 

While that engine is arguably better with its excellent performance, smaller dimensions and lighter weight, the fact remains that for many of Aston Martin’s long-time buyers, it’s V12 or nothing.

It also helps that the V12 produces an extremely potent 614kW and 1000Nm, which is way ahead of the 611kW/678Nm the Ferrari 12Cilindri makes. So you get bragging rights at the golf club with your Ferrari mates.

The engine features a unique titanium exhaust and is paired with an eight-speed automatic transaxle that drives the rear wheels.

That is enough to propel the Vanquish to a top speed of 345km/h, making it the fastest production car the brand has ever produced, with a 3.3 second 0-100km/h time.

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.

To say the Vanquish isn’t the most fuel frugal vehicle on the market is an obvious statement, but even its claimed 13.7L/100km is best described as optimistic.

That’s not surprising given its size and performance, but with an 82-litre fuel tank that’s a driving range of less than 600km, at best.

In the real world, during our time in the Vanquish, the car’s trip computer was indicating that we stayed in the high teens; although that featured limited freeway/extra-urban driving.

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.

As cars go, few can match what the Vanquish offers. Even in my 20+ years of driving every type of car imaginable, the Vanquish stands out as being something distinct, bold and special.

Sitting behind the wheel, the bonnet looks like it stretches out to the horizon and you feel like you’re sitting on the back axle of the car. And yet, when you start driving, the Vanquish feels like it shrinks around you.

At normal speeds it feels like a classic grand tourer, relaxed, refined and easy to drive. Obviously it's a firmer ride than your average luxury car, but that’s a small price to pay for the breadth of capability this car offers. 

Because once you get out of the urban environment, the Vanquish becomes something else entirely. On a winding road this British beast is surprisingly agile for such a big car.

The steering feels direct and the front end responds with much more precision and poise than you should reasonably expect from a car with such an exaggerated bonnet.

No, it doesn’t have the dynamic aggression the more compact Vantage offers, but it manages to take elements of that car and combine it with the GT nature of the DB12 to give you the best of both Aston Martin’s coupes.

Of course, the catch is it’s much too fast for Australian roads and isn’t really designed to be a track day car, so in Australia - without autobahns or more liberal views on speeding - the Vanquish in many respects doesn’t make sense.

But that is arguably its driving essence, you buy it because you know what it’s capable of, even if you’ll rarely use it, and that is an absolute luxury.

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.

The Denza B5 received a five-star ANCAP safety rating based on testing conducted in 2025.

As standard there are 11 airbags, autonomous emergency braking (AEB), blind-spot monitoring, front and rear cross-traffic alert, adaptive cruise control, a driver attention monitor, front and rear parking sensors, plus a surround-view camera.

While a number of the active safety systems operate well and only intervene when required, some are intrusive and over the top. The worst offender is the driver attention monitor which struggles to detect your eyes with sunglasses on, plus only requires a brief glance at the touchscreen to get it saying, “Tiredness detected, please take a rest”.

Thankfully you can turn this off using the touchscreen with the handy swipe-down control centre menu, but it needs to be done every time you drive the car.

Despite the extraordinary price tag the Vanquish is covered by a very standard three-year/unlimited kilometre warranty. It’s a surprising, and some might argue disappointing, short period of coverage for a car that is not only expensive but should have a long life.

However, it does redeem itself in some way by including the first five years of servicing into the cost of the car. Ferrari offers seven for its models, so Aston Martin is still behind the market, but included servicing feels right for a car costing nearly $1 million once you put it in traffic.

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.
