Denza B5 vs BMW 128TI

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.

It might not be rear-wheel drive, but the 128ti is a thoroughly enjoyable BMW to steer, proving the 'f' in front-wheel drive can stand for fun. It’s a very good hot hatch.

And given how expensive mainstream hot hatches have become, the 128ti is a bargain, giving would-be Golf GTI, Focus ST and i30 N buyers a thing or two to think about.

After all, the 128ti is a premium hot hatch by virtue of the BMW badges it wears and the higher quality of its parts, but not its price. And for that reason, it cannot be ignored.

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.

You can count me among those who aren't fans of the 1 Series' version of BMW’s 'kidney' grille. It’s not just out of proportion, but arguably, misplaced.

In fact, it just spoils the front end, although I'm also not a fan of the bumper's 'smiling' centre air intake.

But, thankfully, that’s where my unfavourable opinion ends, as the angular headlights and hexagonal DRLs look the part, while the 128ti's red-trimmed side air intakes bring a sense of occasion.

And you better be a big fan of red trim, as the 128ti liberally applies it around the side, where the brake calipers have some presence behind the attractive 18-inch Y-spoke alloy wheels. And don’t forget the side skirt insert and 'ti' decal!

At the rear, aside from the obligatory '128ti' badge and the relatively subtle red-trimmed side air intakes, there isn’t much to separate the 128ti from a garden variety 1 Series, but that’s no bad thing as it's its best angle.

The sporty rear spoiler, sleek tail-lights, stupendous diffuser insert and scintillating dual exhaust tailpipes are gorgeous. And the 128ti is attractive in profile, thanks to its appealing silhouette and smoothly sculpted lines.

Inside, the 128ti stands out from the 1 Series crowd with the red stitching applied to the steering wheel, seats, armrests and dashboard, while the floor mats have – you guessed it – red piping.

The most interesting design flourish, though, is the red-stitched ti logo on the centre armrest. That's one way to make a statement, and it all combines to make the 128ti feel special.

And being a 1 Series is a leg-up in the first place, as high-quality materials are used throughout, in concert with a simple but effective design.

Mercifully, the centre stack features physical climate and audio controls, while the centre console has an appropriately sized gear selector and a rotary dial to control the multimedia system.

That's right, the 128ti has multiple input methods aside from the 10.25-inch central touchscreen and voice control, making it a relative breeze to operate, especially with Apple CarPlay and Android Auto support of the wireless variety.

That said, there's plenty of room for improvement for the 128ti's 10.25-inch digital instrument cluster, which lacks the breadth of functionality of its competitors.

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.

Measuring 4319mm long (with a 2670mm wheelbase), 1799mm wide and 1434mm tall, the 128ti is a small hatchback in every sense of the term, but it makes the most of its size.

The boot's cargo capacity is competitive, at 380L, although it can be increased to a more accommodating 1200L by stowing the 60/40 split-fold rear bench.

Either way, there's a decent load lip to contend with, but four tie-down points, two bag hooks and a side storage net are on hand for securing loose items.

In the second row, there's a welcome four centimetres of legroom behind my 184cm driving position as well as a centimetre or two of headroom, even with our test car’s optional panoramic sunroof.

Three adults can sit on the rear seats on short journeys, but they will have next-to-no shoulder-room, plus a large central tunnel (necessary for AWD 1 Series variants) to deal with.

Young children are accommodated, though, with two ISOFIX and three top-tether anchorage points available for fitting child seats.

Amenities-wise, those in the back have access to the storage nets on the front seat backrests, clothes hooks, the centre console's directional air vents and two USB-C ports.

The door bins can take a regular bottle each, but there isn't a fold-down armrest with cupholders.

Up front, the glove box is surprisingly large, while the driver-side cubby is not only decently sized, but two-tiered. The central storage bin is also solid, and has a USB-C port hidden inside.

Ahead of that are a 12V power outlet, a pair of cupholders, a USB-A port and a narrow, open cubby that should house a wireless smartphone charger (but doesn't). And yes, the door bins are ready to swallow a regular bottle apiece. So, pretty damn good overall.

Priced from a tempting $55,031, plus on-road costs, the 128ti finds itself right in the thick of the hot-hatch action, with its M135i xDrive big brother at least $10,539 dearer, while its most direct rival, the Golf GTI, is just $541 cheaper.

Of course, more affordable FWD hot hatches are available, and they're more potent than the 128ti and GTI, including the Ford Focus ST X ($51,990) and automatic Hyundai i30 N Premium ($52,000).

Either way, the 128ti stands out from the 1 Series crowd with its bespoke steering tune, lowered sports suspension (-10mm), black grille, unique two-tone 18-inch alloy wheels with 225/40 Michelin Pilot Sport 4 tyres, upgraded brakes with red calipers, and black side-mirror caps.

There's also red trim on the front and rear air intakes, and side skirts, with 'ti' decals positioned above the latter. The steering wheel, seats, armrests, dashboard and floor mats have similarly coloured accents.

Other standard equipment includes a body kit, dusk-sensing adaptive LED headlights, rain-sensing wipers, a tyre repair kit, power-folding side mirrors with heating and puddle lights, keyless entry and start, a 10.25-inch touchscreen multimedia system, satellite navigation, wireless Apple CarPlay and Android Auto support, digital radio and a six-speaker sound system.

And then there’s a 10.25-inch digital instrument cluster, a 9.2-inch head-up display, dual-zone climate control, a sports steering wheel, power-adjustable front sports seats with memory functionality, an auto-dimming rearview mirror, black/red cloth and synthetic leather upholstery, 'Illuminated Boston' trim, ambient lighting and M seat belts.

Options include a $3000 'Enhancement Package' (metallic paintwork, panoramic sunroof and adaptive cruise control with stop and go functionality), which was fitted to our test vehicle for an 'as tested' price of $58,031.

Other key options include a $1077 'Convenience Package' (power tailgate, boot storage net and ski port), a $2000 'Executive Package' (alarm, rear privacy glass, 10-speaker hi-fi sound, gesture control and tyre pressure monitoring) and a $1023 'Comfort Package' (heated steering wheel, and front seats with lumbar support).

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.

The 128ti is motivated by a familiar 2.0-litre turbo-petrol four-cylinder engine, with its version producing a promising 180kW of power at 6500rpm and 380Nm of torque from 1500-4400rpm.

Disappointingly, Australian examples are detuned relative to their European counterparts, which are 15kW/20Nm more potent due to their market-specific set-up.

Either way, drive is sent to the front wheels via a dependable ZF eight-speed torque-converter automatic transmission (with paddle-shifters) and a determined Torsen limited-slip differential.

This combination helps the 128ti sprint from a standstill to 100km/h in a brisk 6.3 seconds while on the way to a not-in-Australia top speed of 243km/h.

For reference, competitor outputs are: M135i xDrive (225kW/450Nm), Golf GTI (180kW/370Nm), i30 N Premium (206kW/392Nm), and Focus ST X (206kW/420Nm).

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.

The 128ti's fuel consumption on the combined cycle test (ADR 81/02) is a promising 6.8L/100km, while its carbon dioxide (CO2) emissions are 156g/km.

However, in real-world testing, I averaged a reasonable 8.4L/100km over an even combination of urban and highway driving. Without my heavy right foot, an even better return could be had.

For reference, the 128ti's 50L fuel tank takes more expensive 98 RON premium petrol at minimum. Its claimed driving range is 735km, but in my experience, I got 595km.

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.

So, can a FWD BMW be fun to drive? As far as the 128ti is concerned, the answer is a resounding yes.

Yes, you get the feeling you’re being pulled rather than pushed, but the 128ti attacks corners with entertaining vigour.

Of course, the 2.0-litre turbo-petrol four-cylinder engine’s 180kW/380Nm outputs can easily overwhelm the front wheels off the line, and torque steer is a threat, particularly when pushing hard around bends, but they’re welcome characteristics.

After all, corner exits are improved by the 128ti’s Torsen limited-slip differential, which works hard to optimise grip when you need it most.

When going for the jugular, understeer still rears its ugly head, but wrestling the 128ti into shape is half the fun.

That said, body control isn't quite as strong as hoped. Turn in sharply and the 1445kg 128ti generates a surprising amount of roll.

It’s worth noting the lowered sports suspension goes without adaptive dampers, its fixed-rate set-up attempting to find the delicate balance between comfort and dynamic response.

All in all, the 128ti's ride is firm but well judged, with short, sharp imperfections the only real bother. Needless to say, it’s capable of being a daily driver, and so it should be.

As mentioned, the electric power steering has a unique calibration, and it's nice and direct, with a good amount of feel. But if you prefer more heft, simply engage 'Sport' mode.

Speaking of which, the Sport drive mode also releases the full potential of the engine and the eight-speed auto, sharpening up the throttle and raising the shift points.

The 128ti engine is a gem, offering up plenty of punch, especially throughout the mid-range, where torque is at its fattest and power is about to peak. The accompanying soundtrack also has some presence, even if it is artificially 'enhanced.'

But the smooth yet relatively quick shifting automatic transmission can take plenty of credit for the brisk performance on offer.

That said, the 128ti's first and second ratios are surprisingly short, so pay attention if you take matters into your own hands via the steering wheel’s paddle shifters.

The 128ti and the wider 1 Series range received a maximum five-star rating from independent Australian vehicle safety authority ANCAP in 2019.

Advanced driver-assist systems in the 128ti extend to autonomous emergency braking (AEB) with pedestrian and cyclist detection, lane-keep assist, cruise control, speed sign recognition, high-beam assist, driver attention alert, blind-spot monitoring, active rear cross-traffic alert, park assist, rear AEB, a reversing camera, front and rear parking sensors, and 'Reversing Assistant.'

That said, annoyingly, adaptive cruise control with stop and go functionality is part of the 128ti’s optional Enhancement Package fitted to our test vehicle, or as an individual option.

And tyre pressure monitoring is tied to its extra-cost Executive Package. Both should be standard.

Also included are six airbags (dual front, side and curtain), anti-skid brakes (ABS) and the usual electronic stability and traction control systems.

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.

Like all BMW models, the 128ti comes with a three-year/unlimited-kilometre warranty, which is two years off the five years/unlimited km premium benchmark set by Audi, Genesis, Jaguar/Land Rover, Lexus, Mercedes-Benz, and Volvo.

The 128ti also comes with three years of roadside assistance, while its service intervals are average, at every 12 months or 15,000km, whichever comes first.

Capped-price servicing packages are available, with three years/40,000km starting from $1350, while five years/80,000km kicks off at $1700. The latter, in particular, offers great value.
