Mercedes-Benz GLB-Class vs BYD Dolphin

What's the difference?

It’s easy to say the GLB35 doesn’t deserve to be called an AMG when looking at its credentials on paper, but get behind the wheel and it’s evident Affalterbach played a key role in making it feel as special to drive as it should be.

The GLB35 has all of the great qualities of the GLB250 and other GLB variants, but successfully adds a performance focus to make for an even more compelling package.

Indeed, the GLB35 proves you can pretty much have it all.

Chinese manufacturers have been impressing us lately with the strides they’ve been making, and BYD is no exception with its Dolphin.

Not only does this hatch help bring the price down for prospective EV buyers, but it leaves a solid impression of a cohesive, well-built car, which is also quite a bit of fun to drive.

It’s not the fastest, nor is it the most practical, and there are a handful of downsides to its design and software, but when it comes down to it, this is simply a great value entry-level electric car.

With the boxy and therefore rugged-looking GLB laying some great foundations, it’s no surprise the GLB35 looks pretty damn good – to these eyes, at least.

Being an AMG model, it stands out from the crowd with an aggressive body kit, with the chunky bumpers, aerodynamic roof spoiler and racy rear diffuser all unique alongside the now-signature Panamericana grille insert.

A set of 20-inch alloy wheels with 255/40 tyres ups the ante at the side, where the carryover black plastic wheel-arch and skirt cladding serves as an obligatory reminder that this is an SUV.

Also of note are the nicely designed LED headlights and tail-lights, which literally light the way, but there’s no getting past the bespoke diffuser element, which integrates the sports exhaust system’s dual 90mm tailpipes.

Inside, the GLB35 is a technological tour de force, with a pair of 10.25-inch high-resolution displays proudly sitting side by side atop the dashboard, with one the central touchscreen and the other the digital instrument cluster.

Both are powered by Mercedes-Benz’s MBUX multimedia system, which arguably remains the best there is today thanks its speed and breadth of functionality and input methods.

The GLB35 is also properly premium. Lugano leather upholstery covers the seats and armrests, while Nappa trims the sports steering wheel. Even the door shoulders and inserts get ‘cow hide’, although theirs is of the artificial variety.

Soft-touch materials are used for the upper dashboard, leaving hard plastics to the lower sections, which is what you’d expect for the price.

While the black headliner makes for a dark cabin, brightness comes from the metallic trim used throughout, notably on the steering wheel, dashboard, doors and centre console. And let’s not forget the pop of colour provided by the addictive ambient lighting.

And mercifully, scratch- and fingerprint-hungry gloss-black accents are limited to the surrounds of the turbine-style front air vents, dual-zone climate controls and centre console.

Unique to the GLB35 are Carbon Structure trim and stainless-steel sports pedals, just in case you forgot you weren’t driving a regular GLB.

You wouldn’t know it in Australia, but BYD has a huge and diverse range of vehicles with lots of different styling approaches in its home market of China.

The cars we get here, though, consisting of this Dolphin hatch, the Atto 3 small SUV, and the upcoming Seal sedan all seem to share more or less the same curvy, futuristic theme.

Contemporary touches on the exterior of the Dolphin include the bar light and full ‘Build Your Dreams’ typeface embedded in the rear, the blocky gloss black alloy wheels (17-inch on the Premium we tested), the two-tone colour scheme, and of course, the grille-free face.

Short overhangs and a tall body seal the EV deal, with the Dolphin looking closest in its aesthetic to something like the Volkswagen ID.3 than anything else on the market. It perhaps won’t be for everyone - it’s a little more experimental than the more conventional look worn by the MG4 - but then, for others this distinctiveness may be a selling point.

The interior look and feel is the biggest surprise. Somehow, the Dolphin, despite being more affordable than its larger Atto 3 sibling, feels a cut above when it comes to its design theme and build quality.

The weirdly organic touches designed to mimic muscle fibres in the Atto 3 have been traded out in favour of something a bit slicker.

I really like the material choices here. The use of neoprene across the lower half of the dash, in the doors, and down the centre of the seats feels a lot less pretentious than the standard synthetic leathers you usually get at this price-point, and there’s an agreeable mix of plastics as well as gloss and matt finishes. 

The nods to this car’s name which are present are a bit more toned down and fit with the design in a more subtle way.

The floating door handles, designed to resemble a fin, are a much nicer piece than the weird rotary ones in the Atto 3, and the wavy touches across the top of the dash aren’t too in-your-face and add an element of intrigue. I like it much more than I expected to.

It’s clear this space is designed around the giant multimedia panel, for better or worse. It looks spectacular, it’s nice and sharp, and the software, which looks as though it’s trying to emulate Tesla, does a pretty good job.

It’s quick, sharp, colourful, and has nice large iconography to jab at while you’re on the move, although some of the driving settings are ambiguously labelled and require clicking through to a sub-menu to alter. You’d get used to it, but it isn’t as slick as a Tesla operating system.

It also rotates, because of course it does, although one quirk I found with this is the polarised coating on the screen made it impossible to see when in portrait mode if you were also wearing polarised sunglasses.

Also, Apple CarPlay doesn't work in portrait mode. A gimmick? You decide.

The floating physical rotary controls jutting out below are a also a brilliant little piece of design. On one side you have your gear shifter, and on the other you’ve got your volume control, between them there are core functions, an on/off switch and an auto button for the climate, as well as the hazard light and drive mode controls.

It would be nice to also have a fan speed and temperature toggle, as these functions can only be used through the touchscreen, but there are worse offenders for clumsy climate controls on the market.

Measuring 4650mm long (with a 2829mm wheelbase), 1845mm wide and 1660mm tall, the GLB35 is more like the GLC43 in size than the GLA35, making it a mid-size SUV despite its small underpinnings. And that is good news for practicality.

Cargo capacity with the 50/50 split-fold third row stowed is more than solid, at 565 litres (VDA), but it can be increased to a cavernous 1800L with the 40/20/40 split-fold middle bench also not in use. If six or seven passengers are onboard, though, there’s very little room to move.

Nonetheless, the boot is still well packaged, featuring a huge aperture, no load lip, and a flat floor, which make loading and unloading bulkier items a hell of a lot easier. And even the load cover can be stored underfloor when out of action. How good.

There are also four tie-down points, two bag hooks, a side storage net and a 12V power outlet on hand to make matters even easier, while the rear seats can be stowed from the boot.

While we’re on the topic, Mercedes-Benz says the third row can accommodate passengers up to 168cm tall, with the middle bench able to slide fore and aft by up to 140mm.

Yes, I'm too tall, at 184cm, but I can still sit in the very back, although not in total comfort. All in all, about a centimetre of legroom and negligible headroom and toe-room are on offer there for me.

That said, getting in and out in the first place is the real challenge here, with the middle bench unable to tumble forward for easy ingress and egress. Yep, you’re not going to look smooth either way. Children can deal with it, but adults won’t be thrilled.

Therefore, the middle bench is the place to be, even when it’s slid all the way forward. Behind my driving position, it offers about a centimetre of legroom, but this can be increased to several inches by sliding it all the way back.

Either way, plenty of toe-room is available alongside more than an inch of headroom. The latter is more impressive when you consider that’s what you get with the standard dual-pane panoramic sunroof fitted.

Even better, the second row can seat three adults at a pinch, partly thanks to the low transmission tunnel, which means there’s the right amount of space for six fully grown feet across the two footwells. It goes without saying children will again be fine.

Speaking of which, four ISOFIX and five top-tether anchorage points are on hand for fitting up to four child seats across the second and third rows, which makes the GLB35 a serious option for families that like to be sporty.

There are plenty of in-cabin storage options, with the large central storage bin featuring a pair of USB-C ports, while the glovebox is also quite useful, even if it is oddly shaped. And there’s also a sunglasses holder in front of the rearview mirror.

The centre console’s cubby isn’t really designed for storage, with it basically taken up by two cupholders, another USB-C port and a wireless smartphone charger.

The front door bins can accommodate one small and two regular bottles each, which is great, while their rear counterparts can take one small and one regular apiece.

Second-row occupants also have access to a fold-down armrest with another pair of cupholders, but being of the retractable variety, they’re flimsy.

These passengers also have two USB-C ports, with the pair folding out below a small cubby and air vents, which are found at the back of the centre console. Storage nets are also fitted on the front seat backrests.

And don’t worry; the third row gets in on the action, with two cupholders (one regular, the other small) splitting the seats, which have individual USB-C ports and device straps to the sides.
 

The clever design bits don’t end with the controls and themed motifs, either. While the Dolphin’s cabin feels a bit smaller than many of its rivals (because, physically, it is), efforts have been made to make it a versatile space. 

There are plenty of little storage areas throughout. There’s the floating one below the touchscreen, which suits wallets and sunglasses. There’s one with a roll-out cover set low below the controls which is good for smaller objects you don’t want moving around the cabin.

A large cubby is located underneath the armrest between the two seats for bigger objects and a slick wireless phone charger cut out from the top.

The two centre bottle holders are a little small, as are the cut-outs in the doors, so if you’re negotiating with an XL takeaway soft drink you might run into trouble.

The dark theme for the interior in our car doesn’t help the more closed-in feel, but the standard panoramic fixed sunroof (mercifully with a rolling shade) helps to keep the space airy.

I found it easy to set up my driving position, another clever touch being the little digital instrument panel perched on the steering column, so no matter how you adjust it you can always see it.

I was a little concerned the rear seat would be tiny, because this car doesn’t look big from the outside, but I was most definitely wrong.

Behind my own seating position, at 182cm tall, I had leagues of knee room and plenty of space for my feet thanks to the flat floor. I also had sufficient but not stellar headroom, and the soft-touch materials continue into the doors and seat trim.

I will say, the abundance of synthetic leather is much more evident for rear passengers, but it feels like a minor complaint.

Again, the bottle holders in the doors are tiny, but at least the ones in the drop-down armrest are generous. The middle seat is very useful thanks to the flat floor, although there are no adjustable air vents for rear passengers.

The backs of the front seats have a variety of pockets in different shapes and sizes, and there are USB-C and USB-A ports on the back of the centre console, alongside a bizarre centre bottle holder which is on an angle.

Boot space is 345 litres if you move the false floor to its lowest position. I was just able to squeeze in the three-piece CarsGuide luggage set with a bit of fiddling around.

With the second row down, room expands to 1310L, and you can bring the false floor up in the boot to make the load area flat.

The space underneath is quite good for storing charging cables and such, but keep in mind the Dolphin doesn’t offer additional frunk storage.

What it does offer is a vehicle-to-load adapter, which lets you power household appliances via its external charging port. Neat, and rare at this end of the EV market.

Yep. This is the new cheapest electric car you can buy in Australia. This title is a frequently moving target, but again, at the time of writing, the entry-level Dolphin variant, at $38,890, before on-road costs and state-based incentives, undercut the MG4 by just $100, and the GWM Ora by $1100.

Importantly, its starting price is now in the realm of relevant combustion rivals. For similar money, you can hop into a high-spec Corolla (ZR Hybrid $39,100) for example, so this is the first time electric cars have become so affordable for the average consumer.

There are two Dolphin variants for now. The entry-level Dynamic, and the top-spec Premium. Both share more or less the same standard equipment levels, although they are differentiated by having different battery sizes and electric motor outputs.

You can’t talk electric car value without talking range, but thankfully, despite its low price, the Dolphin delivers on this front.

The base car scores a 44.9kWh battery, granting it a 340km WLTP-certified driving range, while the top-spec Premium ups this to a 60.5kWh unit, delivering a more substantial 427km range.

The entry battery is more than enough for city commuters, while the larger battery is enough to suit intercity freeway drives.

There are also plenty of longer-range EVs on the market, the Polestar 2 and Tesla Model 3 being chief among them, but for a vehicle at this price and in this market segment, the Dolphin is a huge improvement on some mainstream offerings, like the Mazda MX-30 and Nissan Leaf which can’t offer the same price-to-value ratio.

A lot of BYD’s ability to provide such an appealing price and driving range is down to its battery technology.

Unlike other automakers which need to buy batteries from suppliers, BYD designs and builds its own batteries, using an LFP chemistry which is cheaper and uses fewer scarce materials while offering economies of scale as well as the exact right size and form factor for its vehicles.

If this leaves you thinking the Dolphin must be sub-par when it comes to standard inclusions, you can think again, because this car also delivers with 16-inch alloys, LED headlights and tail-lights, a massive 12.8-inch multimedia touchscreen with built-in nav as well as Apple CarPlay and Android Auto connectivity, a wireless phone charger, electrical adjust and heating for the front seats, keyless entry with push-start ignition, climate control, and a comprehensive suite of active safety items.

Not bad at all, and the interior blend of neoprene and synthetic leather feels a bit nicer than the base MG4's cabin, for example.

The Dolphin might be as cheap as it gets when it comes to an electric car, but the value on offer here speaks for itself.

The GLB35 is powered by an uprated version of the GLB250’s 2.0-litre turbo-petrol four-cylinder petrol engine, with the AMG-fettled version producing a more substantial 225kW of power from 5800-6100rpm and 400Nm of torque from 3000-4000rpm (up from 165kW/350Nm).

This version is also matched to an eight-speed dual-clutch automatic transmission as well as Mercedes-AMG’s front-biased but fully variable 4Matic all-wheel-drive system.

Thanks to this combination, the GLB35 can sprint from 0-100km/h in just 5.2 seconds with launch control enabled, while its electronically limited top speed is 250km/h.

There’s the choice of two powertrains for the Dolphin. Both are single-motor front-wheel drive set-ups.

The base Dynamic can make use of 70kW/180Nm which sounds underpowered to me, but the car we tested for this launch review was the Premium which offers a much healthier 150kW/310Nm.

As well as the increase to battery capacity the Premium upgrades the suspension to a rear multi-link set-up.

While the base car seems like such a value buy, the increase in power, ride quality, and range seems to justify stretching to the Premium if your budget allows.

The GLB35’s fuel consumption on the combined-cycle test (ADR 81/02) is 8.3L per 100km, while its carbon dioxide emissions are 186 grams per km. All things considered, both claims are pretty decent.

In our real-world testing, though, we averaged a high 14.1L/100km over 75km of driving split between highways and country roads, so not your typical mix, then. A heavy right foot also played into that result, so expect a better return after a regular run.

For reference, the GLB35’s 60L fuel tank can be filled up with 98RON petrol at minimum.

As previously mentioned, each variant also gets its own battery capacity. The entry-level Dynamic offers a 44.9kWh battery and 340km of driving range, while the top-spec car offers a 60.5kWh unit with a driving range of 427km.

Charging on a fast DC unit maxes out on 60kW for the Dynamic or 80kW for the Premium.

This sounds slow, with many rivals offering in excess of 100kW charging at a minimum, but because the Dolphin’s battery sizes are so trim, it still means an 80 per cent charge will arrive in a little over half an hour.

On the slower AC charging standard, the max speed is a disappointing 7.0kW. For a fully electric car, we prefer to see at least 11kW as it makes it worthwhile to plug-in to an AC unit at a shopping centre to add roughly 70 - 100km of range an hour.

Because the Dophin is also quite efficient, though, you can still expect about 50km an hour to be added on this charging standard.

Official energy consumption for the Premium as-tested is 14.2kWh/100km, and we saw an impressive 14.1kWh/100km on our brief test program, making it one of the more efficient EVs I’ve ever driven.

Don’t let the GLB35’s family friendliness fool you, this is an SUV that can get up and go.

The engine’s extra power and torque over the GLB250 are immediately felt behind the wheel, with the GLB35 accelerating with the vigour of an all-wheel-drive hot hatch, which makes sense given their similar claims.

And if you have one of the sportier drive modes engaged, the booming noise generated is also special – even if a lot of it is of the artificial variety, pumped into the cabin to make occupants feel like things are getting serious.

What is genuine, though, is the well-rounded transmission, which is characteristically quick with its upshifts. At the same time, it’s also relatively smooth, even at low speed, which has proven to be a challenge for dual-clutch units over time, but not here.

To earn the AMG badge, the GLB35 goes even further with other mechanical upgrades, including sports tunes for the suspension and steering.

Specifically, the GLB35’s independent suspension set-up not only consists of MacPherson-strut front and trailing-link rear axles with adaptive dampers, but also introduces new steering knuckles, transverse control arms on the front axle, and a stiffened subframe.

The resulting ride is actually quite good. Yes, the extra firmness over the GLB250 is noticeable – particularly in the sportier drive modes that stiffen the adaptive dampers all the way – but it’s by no means a deal-breaker.

That said, it’s worth noting our test vehicle was fitted with the optional 21-inch alloy wheels ($1990), so the GLB35’s like to ride even better on its standard package.

This is remarkable considering the handling improvements made, with the GLB35 managing body roll and pitch better than the GLB250 when pushing hard into and around corners, coming out of which grip is plentiful thanks to the all-wheel-drive system.

Thankfully, the standard-fit high-performance braking package consisting of 350mm front and 330mm rear discs with four- and one-piston callipers respectively helped it wash speed away with ease when attacking the twisty stuff with intent, even with 1857kg (kerb) to deal with.

Also on hand is electric power steering, which is speed-sensitive and has a variable ratio in the GLB35. Basically, it’s quicker when you want it to be, remaining on the lighter side in hand until you engage one of the sportier drive modes and weight is increased markedly.

The Dolphin is immediately impressive. From the get-go I was greeted with a feeling of quality from the car in ways I didn’t expect. The steering feels nicely balanced and not too artificial like it can be on some EVs, while the interior is refreshingly ergonomic.

The ride might be the Dolphin’s most impressive trait, with a feeling of balance across both axles, and a spritely feel to the whole car.

It is trim for an EV, with a kerb weight of 1658kg, which no doubt helps the steering feel, and the efficiency.

As it is, I didn’t experience the kind of crashing and wallowing many EVs suffer from on larger bumps, and smaller bumps seemed to be filtered out with ease.

It even feels nicely balanced in the corners, pairing nicely with the great steering feel which is not something we’ve come to expect from Chinese cars.

The motor is also willing, with software tuning keeping power delivery on the right side of overwhelming, although the warm-hatch equivalent's seven second 0-100km/h sprint time is a hint at what it’s capable of.

Unfortunately, it is let down by a pretty sub-standard factory tyre package. The LingLong Comfort Masters are designed for the Dolphin, complete with little Dolphin markings on them, but are hardly inspiring for traction when you plant the accelerator or tip it into a corner with enthusiasm.

They are better than the pretty much no-name Atlas Batman A51 tyres which came on the Atto 3, but even MG has wised up to putting tyres from renowned manufacturers on its Australian-delivered cars.

The Dolphin is also easy to park, thanks to its excellent surround camera suite and tight footprint, but visibility out of the tiny rear window is limited and made worse by the huge headrests for the outboard back seats.

In terms of electric driving characteristics the Dolphin offers two levels of regen braking, one which is virtually non-existent, and another mild tune.

Surprisingly, there’s no single-pedal mode, and the Dolphin leans on blended braking more than some of its rivals. It feels a lot more traditional to drive in this sense, so may be well suited to someone hopping out of a combustion car.

The drive modes are quite dramatic, with 'Eco' mode limiting motor torque and even switching off the climate control, while 'Sport' will make bouts of wheelspin a bit too easy by upping the response time from the motor. I found it best to stick to the nicely-balanced 'Normal' setting.

Tl;dr? The Dolphin is impressive. It’s responsive, relatively light, and has a sense of quality to it through its great ride and decent handling. Not bad for the cheapest EV in Australia.

The Dolphin was recently awarded a maximum five-star ANCAP safety rating and is equipped with seven airbags and a robust list of active safety gear.

There’s auto emergency braking, lane keep assist, blind-spot monitoring, driver attention alert, rear cross-traffic alert, front cross-traffic alert, traffic sign recognition, and adaptive cruise control.

It’s one thing to have great active safety items, it’s quite another to calibrate them well so they don’t interfere with the driving experience.

The Dolphin does okay on this front. I found the lane keep system could occasionally be alarmingly heavy-handed, although it activates less than the very annoying system on my Haval Jolion long-termer.

The pre-collision alert also triggered several times due to parked cars on the side of the road, but turning down the sensitivity seemed to solve this problem.

Also included is an excellent 360-degree camera suite, ISOFIX points on the rear outboard seats, a ‘child presence detection’ system, which apparently sounds a warning if you leave a child in the back seat, and turns the air conditioning on if you ignore it, and there's even a tyre pressure monitoring system to top it off.

As with all Mercedes-AMG models, the GLB35 comes with a five-year/unlimited-kilometre warranty, which currently sets the standard for the premium market. It also comes with five years of roadside assistance.

The GLB35’s service intervals are long, at every 12 months or 25,000km (whichever comes first). Better yet, it’s available with a three-year/75,000km capped-price servicing plan, but it costs $2750, with the third visit alone incurring a $1300 charge.

The Dolphin is covered by a six-year or 150,000km warranty, which beats a lot of mainstream rivals for its duration, but not its distance.

In the EV segment it plays in, though, things are a bit tougher, as its primary Chinese rivals, GWM and MG, are offering seven year and unlimited kilometre warranty promises.

Service pricing is available all the way out to 96 months or 160,000km, averaging $299 per year for the duration, which is pretty good.

Many rivals are offering free servicing for several years, and there are also many electric cars which only need to see a shop once every 24 months or 20,000km, compared to the Dolphin’s more traditional 12 month intervals.
