What's the difference?
Meet the world’s most aerodynamically efficient passenger car. Mercedes-Benz says the drag co-efficient for this new sedan version of its fourth-generation A-Class is the lowest ever measured for a passenger vehicle.
Which is quite a claim, but you only have to look at it to see how much work has gone into marrying good looks with slippery aero performance.
The A-Class sedan is substantially longer and fractionally taller than its hatchback sibling, but does that mean it’s better, or simply different?
So, you want an SUV with seven seats for the family (and maybe friends), but also want it to be premium and have a performance focus. There hasn’t been a model that fits the bill this side of six figures… until now.
Yep, Mercedes-Benz’s mould-breaking GLB mid-sizer has officially been given the AMG treatment. Enter the ‘entry-level’ GLB35, which is out to prove you can have your cake and eat it too, especially if you’re the above buyer.
But is the GLB35 trying to do too many things at once? Is it really a jack of all trades, or a master of none? As always, there’s one way to find out: put it to test. We’ve done exactly that, so please read on.
Mercedes-Benz knows its way around a sedan, and this A-Class is a well-equipped, comfortable and efficient city-sized four-door.
But more than that, to my eyes anyway, it’s a perfect example of restrained form matching aero function with beautiful results.
Note: CarsGuide attended this event as a guest of the manufacturer, with travel and meals provided.
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.
A global carmaker can’t hold its head up in public without a formal design strategy, and Mercedes-Benz uses ‘Sensual Purity’ as a guiding principle in developing the look and feel of its current models. It may sound airy-fairy, but I for one reckon it’s accurate in describing the A-Class sedan.
The overall form is flowing and minimalist, the major exception being a hard character line running down the side of the car from the trailing edge of the angular LED headlights and along the top of the doors to link with the tail-lights.
A rear-biased glasshouse emphasises the length of the bonnet, at the same time delivering a broad, muscular stance with short overhangs front and rear.
Ultra-fine panel gaps, careful sealing around the headlights and curved strakes either side of the bonnet keep the look clean and simple, not to mention super-slippery.
The interior has been styled to within an inch of its life, the dash dominated by the slick twin 10.25-inch widescreen ‘MBUX’ display covering instruments, ventilation, media and vehicle settings.
Five signature, turbine-style air vents (three in the centre, and one at each edge) lift the dash’s visual interest, and the quality of fit and finish is top-shelf.
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.
At a bit over 4.5m long, a fraction under 1.8m wide, and close to 1.5m tall the A-Class sedan is 130mm longer and 6.0mm higher than the hatch version.
The A-Class sedan driver is presented with the same sleek widescreen display as found in the hatch, and storage runs to two cupholders in the centre console, a lidded bin/armrest between the seats (including twin USB ports), decent door pockets with room for bottles and a medium-size glove box.
In a swap to the rear, sitting behind the driver’s seat set to my (183cm) position, I enjoyed adequate knee and headroom, although stretching up a to a straight-back position led to a scalp to headlining interface.
In the A 200 a centre fold-down armrest incorporates two cupholders, again there are generous pockets in the doors with room for bottles, and adjustable ventilation outlets are set into the back of the front centre console. Always a plus.
There are three belted positions across the rear, but the adults using them for anything other than short journeys will have to be good friends and flexible. Best for two grown-ups, and three kids will be fine.
One snag is the size of the rear door aperture. Okay for taller people on the way in, but a limb-unfolding gymnastic exercise on exit.
But of course the reason we’re all here is the boot, and the sedan’s extra length translates to an additional 60 litres of luggage space for a total cargo volume of 430 litres (VDA).
Extra space is one thing, but usability is another. The benefit of a hatch is a large opening that allows bulky stuff to find a home, and Merc has pushed the sedan’s boot aperture to just under a metre across and there’s half a metre between the base of the rear window and the lower edge of the boot lid.
That’s made a big difference and access is good, with the rear seats folding 40/20/40 to add extra flexibility and volume. There are also tie-down hooks at each corner of the floor (a luggage net is included) and a netted pocket behind the passenger side wheel tub (with 12-volt outlet).
At the time of writing Mercedes-Benz wasn’t quoting towing specifications, and don’t bother looking for a spare wheel, the tyres are run-flats.
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 A-Class sedan is launching with two variants, the A 200 at $49,400, before on-road costs, and an entry-level A 180, arriving in August 2019 at $44,900.
We’ll cover active and passive safety tech in the safety section, but above and beyond that standard equipment for the A 180 runs to 17-inch alloy wheels, ‘Artico’ faux leather upholstery, the ‘MBUX’ widescreen cockpit display (two 10.25-inch digital screens), auto LED headlights and DRLs, keyless entry and start, auto-dimming rearview mirror, climate-control, sat nav, multi-function sports steering wheel, cruise control, rain-sensing wipers, ‘Active Parking Assist’ (with ultrasonic proximity sensors front and rear), tinted glass, plus nine-speaker, 225W audio with digital radio, as well as Apple CarPlay and Android Auto.
The A200 steps up to 18-inch alloy rims, and adds a dual exhaust system, four-way electrical adjustment for the driver’s seat (with lumbar support), a folding rear armrest (with twin cupholders), adaptive high-beam assist, and a wireless device charging bay.
Priced from $88,535 plus on-road costs, the GLC35 currently sits atop the GLB range, above both the $59,900 GLB200 and $73,535 GLB250.
Standard equipment not already mentioned in the GLB35 includes dusk-sensing lights, rain-sensing wipers, power-folding side mirrors, black roof rails, rear privacy glass and a power-operated tailgate.
Inside, satellite navigation with live traffic, Apple CarPlay and Android Auto support, digital radio, a 225W sound system with nine speakers, keyless entry and start, power-adjustable front comfort sports seats with heating and memory functionality, auto-dimming mirrors, illuminated ‘AMG’ scuff plates and ‘AMG’ floor mats feature.
As is commonplace for Mercedes-Benz models, the GLB35 has plenty of options with most expensive, so you could drive away with a vehicle that’s dearer than you originally thought.
But aside from a spare wheel and some safety equipment we’ll cover in a moment, the GLB35 doesn’t leave much to be desired, which is always a good thing.
Nonetheless, our test vehicle was finished in $1490 Iridium Silver Metallic paintwork, which is one of eight extra-cost exterior colour options.
As mentioned, the GLB250 is a unique proposition, so it’s only comparable rival, the more affordable but less sporty Land Rover Discovery Sport P250 HSE ($78,432).
Both models are powered by the same 1.3-litre (M282) direct-injection four-cylinder turbo-petrol engine as the hatch, the A180 tuned to deliver 100kW (at 5500rpm) and 200Nm (at 1460rpm), with the A 200 bumping that up to 120kW (at 5500rpm) and 250Nm (at 1620rpm).
Drive goes to the front wheels only via a seven-speed dual-clutch automatic transmission.
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.
Claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle is 5.7L/100km for both models, with a CO2 emissions figure of 130g/km.
Over roughly 250km of open highway driving on the launch program the A 200’s on-board computer coughed up a figure of 6.3L/100km. So, the real-world highway cycle figure is higher than the claimed combined number. Which is a miss, but not a massive one, and fuel-efficiency is still pretty impressive.
Minimum fuel requirement is 95 RON premium unleaded, and you’ll need 43 litres of it (plus a 5.0-litre reserve) to fill the tank.
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.
Three things stand out on first meeting with the A-Class sedan – ride comfort, steering feel, and road noise, or rather the lack of it.
The ‘biggest’ compliment you can pay a small car is that it rides like a bigger one, and behind the A 200’s wheel you’d swear the wheelbase was appreciably longer than the 2.7 metres it actually measures.
Over long undulations, even higher frequency bumps and ruts, the A-Class remains stable and composed thanks to a thoroughly sorted (strut front, torsion beam rear) suspension, with beautifully progressive damping a particular highlight.
Electromechanically-assisted steering points accurately and delivers good road feel without any undue vibration. And despite the A-Class launch drive loop covering typically coarse-chip bitumen roads through rural Victoria, overall noise levels remained impressively low.
Acceleration is brisk rather than properly sharp, but in the A 200 there’s more than enough oomph to keep things on the boil for easy highway cruising and overtaking.
With maximum torque available from just above 1600rpm, and a seven-speed dual-clutch auto transmission keeping revs in the sweet spot, the A 200 breezes through the cut and thrust of city traffic, too.
Auto shifts are smooth and quick, with manual changes via the wheel-mounted paddles adding even more direct access to your ratio of choice. And the bonus is no sign of the slow-speed shuntiness sometimes exhibited by dual-clutch autos, especially in twisting, three-point parking manoeuvres.
Special call-out for the cruise control which responds to adjustments quickly (including 10km/h jumps up or down with a firm press of the thumb) and rapidly retards downhill speeds.
Several unbroken hours in the front seat couldn’t generate a twinge of discomfort, the brakes are strong, and over-shoulder visibility is marginally better than in the hatch (not that it’s a weakness in the latter).
Add the sleek and intuitive multimedia system, high-quality audio, plus excellent ergonomics and you have a neatly resolved compact sedan that’s easy to use in the city and suburbs, keeping solid road-tripping ability up its sleeve as well.
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.
Think automotive safety and Mercedes-Benz will be one of the first names to pop into your mind, and the A 180 offers in impressive suite of active features including ABS, BA, EBD, stability and traction controls, a reversing camera (with dynamic guidelines), ‘Active Brake Assist’ (Merc-speak for AEB), ‘Adaptive Brake’, ‘Attention Assist’, ‘Blind Spot Assist’, ‘Cross-wind Assist’, ‘Lane Keep Assist’, a tyre pressure warning system, the ‘Pre-Safe’ accident anticipatory system, and ‘Traffic Sign Assist’. The A 200 adds ‘Adaptive Highbeam Assist’.
If all that fails to prevent an impact you’ll be protected by nine airbags (front, pelvis and window for driver and front passenger, side airbags for rear seat occupants and a driver’s knee bag), and the ‘Active Bonnet’ automatically tilts to minimise pedestrian injuries.
The A-Class was awarded a maximum five ANCAP stars in 2018, and for smaller occupants there are three child restraint/baby capsule top tether points across the back seat, with ISOFIX anchors on the two outer positions.
ANCAP awarded the GLB range its maximum five-star safety rating in 2019.
Advanced driver-assist systems in the GLB35 extend to autonomous emergency braking (AEB) with pedestrian and cyclist detection, lane-keep assist, blind-spot monitoring, rear cross-traffic alert, traffic sign recognition, driver attention alert, tyre pressure monitoring, hill-descent control, hill-start assist, park assist, a reversing camera and front and rear parking sensors.
Is anything missing? Well, steering assist, adaptive cruise control, active blind-spot monitoring and front cross-traffic alert form the optional Driving Assistance Package ($1990), which definitely should be standard at this price point.
And let’s not forget the two other noticeable absentees: surround-view cameras and high-beam assist. They’re annoyingly part of the optional Vision Package ($1190), which was fitted to our test vehicle.
Nonetheless, other standard safety equipment includes nine airbags (dual front, front-side, curtain and rear-side plus driver’s knee), anti-skid brakes (ABS), electronic brake-force distribution (EBD) and the usual electronic stability and traction control systems.
Mercedes-Benz covers its passenger car range with a three year/unlimited km warranty, like the other two members of the German ‘Big Three’ (Audi and BMW) .
That lags behind the mainstream market where the majority of players are now at five years/unlimited km, with some at seven years.
On the upside, Mercedes-Benz Road Care assistance is included in the deal for three years.
Service is scheduled for 12 months/25,000km (whichever comes first) with pricing available on an ‘Up-front’ or ‘Pay-as-you-go’ basis.
Pre-payment delivers a $500 saving with the first three A-Class services set at a total of $2050, compared to $2550 PAYG. Fourth and fifth services are also available for pre-purchase.
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.
