Mercedes-Benz GLB-Class vs Holden Spark

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.

The marvels of local engineering strike again: the Spark LT definitely feels a cut above some of its budget competition from behind the wheel. It is well-equipped, too, and packed with connectivity and technology features. In short, it could be just the spark Australia's city-car segment needs.

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.

There's only so much that can be done with a car in this bracket (there's hardly an abundance of surface metal to play with), but Holden's Korean design team have done an admirable job of inserting some excitement into what is traditionally a fairly bland category.

More youth appeal arrives courtesy of a huge array of personalisation options.

A powerful front end, with two fog lights sitting below the headlights, is dominated by a vaguely Kia-esque grille. And when viewed side on, the Spark looks to be sitting low, courtesy of standard 15-inch alloys that fill the wheel arches and tarmac-kissing side skirting that runs front to back. Two fairly heavy body creases also break up the metal monotony, running along the front and rear doors.

It's an energetic-looking package, and even more youth appeal arrives courtesy of a huge array of personalisation options, with Holden promising 33 different changes a buyer can make, including the wheel inserts, wing mirror caps and roof rails.

Inside, the focus is more on connectivity than luxury, so you can expect fake leather, hard plastics and fairly ordinary seat cushioning, but it's all nicely put together, and the basic feel is broken up by some well-placed style elements, like the coloured insert that runs the length of the dash.

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.
 

Nope. This is a pocket-sized car, namely because it has the same cargo capacity as your pocket.

Holden has stretched the space between the wheels to maximise passenger space, and as a result there's actually plenty of room in either row. But to add space somewhere, you need to take it from somewhere else, and that somewhere else is the boot, where you'll find a mere 185-litres of luggage space. The situation is improved by dropping the 60:40 split rear seats, but you'll be forever choosing between passengers and luggage.

Front seat passengers share a pair of cupholders, but rear seat passengers get none. They don't get room for bottles in their door pockets. Or door pockets at all, for that matter. The backseat does, however, get two ISOFIX attachment points, one in each window seat.

While the cheap and cheerful entry-level Spark, the $13,990 LS, plays smack-bang in the middle of the micro-car segment, the top-spec LT has bigger, and considerably more expensive, shoes to fill. At $18,990, the LT sails perilously close to its bigger and equally well-equipped competition.

For that money, the Spark needs to arrive wanting for little, and in most respects it does exactly that. For a start, a CVT automatic is standard, and is joined by some stand-out features in this segment, like cruise control, keyless entry with proximity unlocking, push-button start and a fake leather trim that Holden calls Sportec.

While navigation isn't standard, the Spark LT's seven-inch touchscreen is both Android Auto and Apple Car Play equipped, so phone maps fill the blank with ease.

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 just the one engine available across the Spark range, and that's a 1.4-litre petrol unit that'll generate 73kW and 128Nm.

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.

Spring for the LT, and that's paired with a CVT automatic transmission, with Holden promising that combination will sip a claimed/combined 5.5L/100km (though we recorded a less impressive 8.0 litres on our test).

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.

Holden's Aussie engineering team say they were able to get their hands all over the new Spark pre-launch, launching lap after lap of the company's proving ground as they tweaked the steering and suspension tune to better suit local conditions. And the results are very good.

The 1.4-litre engine doesn't generate a huge amount of power (though it is good for its class), but it's delivered in a way that makes the Spark feel like it's punching well above its weight, rarely feeling underpowered in everyday situations.

There is a certain skittishness to the way it drives at times.

The Aussie magic sprinkled over the suspension and steering transforms the way the Spark LT drives, both in the city and further afield. The ride nudges the firm side of the spectrum (but not enough to bother you over inner-city ruts and bumps) which translates to a low, flat feeling through corners.

All in all, the little Spark more than holds its own on more challenging roads. The steering, too, helps the Spark outshine the regular city commuters, with a naturally engaging set-up that always feels connected to the road below.

There is a certain skittishness to the way it drives at times, though, with the gearbox wanting to continue lurching forward for a split-second after you take your foot off the accelerator, which takes some getting used to.

Standard safety fare comes courtesy of six airbags, along with hill-hold assist, ABS and ESC, but it does miss out on more advanced technologies like autonomous brakes.

Springing for the LT will add rear parking sensors, a rear-view camera and cruise control as standard fare, though the lot can be added to the entry-level LS as part of Holden's Driver Assistance Pack.

The Spark range scored the maximum five-star ANCAP safety rating when tested early this year.

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 Spark range is covered by a three-year, 100,000km warranty and requires servicing every 15,000kms. The Spark range falls under Holden's lifetime capped price servicing scheme, with trips to the dealership capped at $1,145 total for the first five services.
