Mercedes-Benz GLB-Class vs Skoda Octavia

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.

While other brands may have a higher profile, the quality of this Octavia RS proves Skoda deserves a greater share of the limelight. If you’re thinking about a primo mid-size sedan, or wagon, or even a medium SUV, this car combines satisfying performance with low-to-the-ground dynamics, immense practicality, top-shelf safety and solid value-for-money. It’s nicely put together using quality materials and the ownership package is class competitive. Do yourself a favour and add it to your new-car shopping list.

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.

The current Octavia complies with Skoda’s sharp and angular approach to exterior design, with cool, jagged LED headlight clusters sitting either side of a blacked-out octagonal grille.

A brand signature is the bonnet shutting low and flush over the front guards to create a broad hood panel with longitudinal character lines running down its length. Similar creases flow confidently along the car’s flanks with 19-inch alloys filling the wheel wells nicely.

A smoothly tapering turret ends with a steeply raked rear screen on the sedan and wagon with angular LED tail-lights following a similar pattern to the headlights.

As well as the black grille, car-spotters should look out for the RS’s black finish on the window frame surrounds, roof rails (wagon only) wing mirrors and tailpipes as well as red brake calipers and RS sports bumpers front and rear.

Always a subjective call, but I for one think this car looks distinctive and contemporary while avoiding unnecessary flashiness.

Inside, the treatment is relatively reserved, with a grey through to black colour palette and high-quality materials, including soft-touch surfaces around the dash, doors and console, as well as ‘mouse fur’ and faux carbon sections on the upper dash.

The sports front seats are trimmed in a combination of synthetic leather and synthetic suede with quilted panels in the centre of the cushion and backrest. They feel as good as they look and are easy to get in and out of. Red contrast stitching throughout the interior dials up the racy tone.  

A sizeable central media touchscreen sits proud of the dash with the VW Group’s ‘Virtual Cockpit’ ahead of the driver configurable through multiple set-ups. And a smattering of dark chrome and brushed metal highlights (including on the pedals) finish off a beautifully executed interior.  

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.
 

Practicality is an area where Skoda comes into its own. At every turn the brand’s design and engineering teams have obviously kept day-to-day usability in mind with thoughtful tweaks to make life easier.

Some have become low-key famous like an umbrella slotted into the driver’s door (Rolls-Royce-style) and a small lidded rubbish bin in the driver’s door pocket.

But over and above that, the Octavia’s efficient packaging means in a car measuring just on 4.7m long there’s heaps of room up front for the driver and passenger, with lots of handy storage options. 

Aside from generous door pockets there’s a box between the seats with a padded lid (adjustable for height and length when in use as an armrest), a 15W wireless charging pad (with ventilation from below to keep devices cool), a big glove box (with pen holder), multiple cupholders, a cupholder insert able to hold a phone and/or some coins, numerous oddments trays and a sunglasses compartment overhead (not fitted with optional panoramic sunroof).

And in the back, sitting behind the driver’s seat, set for my 183cm height, there’s tons of leg and headroom with more practical design thinking on display.

For example, map pockets on the back of the front seats have a phone-sized slot stitched into them. There are pull up shades for each window, big bins in the doors with plenty of room for bottles and more, a pull-down centre armrest with fold-out cupholders (plus some oddments space), adjustable climate control vents plus a box on the floor for extra bottles and ‘stuff’ (removable if you need foot room for a centre passenger).

Power and connectivity runs to five USB-C sockets (two front, two rear and one near the rear-view mirror for dashcam duty) plus a 12-volt outlet in the boot. 

Speaking of which, head to the boot and the ‘plenty of room’ theme continues. With the 60/40 split folding rear seat upright there’s 600 litres of space in the sedan and 640 litres in the wagon. Lower the backrest and that number increases to 1555 and 1700 litres, respectively. That’s plenty, and more than the Mazda6.

The sedan and wagon feature anchor points for securing loose loads, extra storage bays behind the rear wheel wells, there’s a ski-port door behind the rear armrest, load divider rails in the sedan, remote release handles for the rear seat, bag hooks, a luggage net… the lot. 

The powered tailgate includes hands-free opening, there’s a space-saver spare under the floor and towing capacity for a braked trailer is 1600kg (750kg unbraked).

Priced at $58,490 for the sedan and $59,990 for the wagon, both before on-road costs, the Octavia RS has one competitor that meets the mid-size sedan and wagon criteria with cost-of-entry somewhere in the same ballpark. And that’s the current Mazda6 20th Anniversary Edition.

Pitched at $54,385, before on-road costs, for the sedan and $55,685 (BOC) for the wagon, the Mazda goes toe-to-toe with the Skoda on size, equipment and performance, although the ‘6’ leans more towards a premium rather than outright performance vibe. And the Mazda has recenetly been discontinued in Australia.

The Accord VTi-LX Hybrid ($59,900, drive-away) puts Honda in the sedan mix and if you’re considering a pure electric medium sedan, the BYD Seal Premium comes in at $58,798, before on-roads while the Tesla Model 3 Single Motor RWD sits at $54,900.

So, aside from the safety and performance tech, covered a little later, what can you bank on in terms of included features for a price tag giving $60K a serious nudge?

The answer is… heaps. Standard equipment on the Octavia RS includes three-zone climate control, adaptive cruise control, a 13-inch multimedia touchscreen, sat nav, 12-speaker Canton audio (with digital radio), a 10-inch configurable digital instrument display, a head-up display, sports front seats (heated with six-way power adjust, memory and massage function), heated rear (outboard) seats, a power tailgate (with hands-free opening), keyless entry and start and rain-sensing wipers.

There’s also ‘Intelligent Park Assist’, LED external lighting (including matrix LED headlights), 19-inch alloy rims, heated and power-folding exterior mirrors (with memory function), synthetic leather and synthetic suede trim, a flat-bottom leather-trimmed steering wheel, alloy finish pedals and rear privacy glass as well as wireless Android Auto and Apple CarPlay. 

Worth noting solid, metallic and pearlescent paint options (seven colours) are included as standard, with the single premium metallic ‘Velvet Red’ colour adding $770. 

That’s as much fruit as you should expect in this part of the market and a bit more.  

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.

The Octavia RS is designated ‘195TSI’ which relates to the power output of its 2.0-litre, four-cylinder, turbo-petrol engine driving the front wheels through a seven-speed dual-clutch auto transmission.

It’s a fourth-generation evolution of the Volkswagen Group’s long-serving ‘EA888’ engine series, an iron block/alloy head unit featuring direct-injection and variable valve timing to produce (you guessed it) 195kW and 370Nm.

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.

The Octavia RS’s official fuel consumption figure on the combined (urban/extra-urban) cycle is 7.0L/100km, the 2.0-litre turbo-petrol engine emitting 159g/km of CO2 in the process (wagon 160g/km).

A start/stop function is standard and on a launch drive program through rural Victoria, covering several hundred kilometres’ worth of urban, B-road and freeway running we saw a (dash-indicated) figure of 6.9L/100km. With a 50-litre fuel tank on board, the RS’s theoretical range is around 715km.

In the city, expect an average in the high 8.0 range, which isn’t out of order for a 1.5-tonne sedan (1.6-tonne wagon).

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.

Skoda claims 0-100km/h acceleration in 6.4 seconds for the Octavia RS sedan and 6.5sec for the wagon and it feels willing with solid mid-range punch available. 

Peak power comes on stream up high (5250-6500rpm) but maximum pulling power is on tap from 1600-4500rpm, which is spot-on for urban running, easy highway cruising and safe overtaking.

A sports exhaust dials up a rorty note when pushing on and the seven-speed dual-clutch transmission proved quick and smooth on a launch drive covering mainly rural B-roads and some freeway sections.

Steering wheel-mounted paddles add extra involvement when you’re in the mood to push through some twisty stuff and select ratios manually.

Speaking of corners, suspension is by struts at the front and a multi-link arrangement (unique to the RS grade) at the rear, with an electronically controlled limited slip differential and ‘Dynamic Chassis Control’ standard. Ride height is 15mm lower than the standard Octavia.

DCC is Skoda code for an adaptive damper set-up and the system offers a ‘Comfort’ mode to help manage bumps, although it adds an air of floatiness on the open road. As the name implies, ‘Sport’ buttons everything down and road imperfections immediately make their presence felt. ‘Normal’ is surprisingly comfortable without upsetting the car’s balance and overall compliance. 

Standard rubber is 225/40 Bridgestone Potenza S005, providing a good grip vs comfort compromise, and the electrically assisted progressive rate rack and pinion steering is accurate, providing good road feel without being too sharp or ‘pointy’. Braking is by ventilated discs all around and the pedal is strong and progressive.

Under the heading of miscellaneous observations, engine, wind and road noise are modest, the grippy sports front seats remained comfortable over several hours behind the wheel, plus a relatively tight 10.4m turning circle and standard 360-degree camera view system make parking easy.  

The current Skoda Octavia was given a maximum five-star ANCAP rating following assessment in 2022. High scores in the adult and child occupant protection categories focused on the stability of the car’s passenger compartment in front offset, full front, side and pole impact crash tests.

For the 2025 model year, standard active (crash-avoidance) tech now includes turn assist and advanced driver fatigue detection, which is on top of auto emergency braking (AEB) operating from 5.0-250km/h (with car and ‘vulnerable road user’ detection plus junction assist), lane keeping assist (and emergency lane keeping), rear AEB, blind-spot monitoring, rear cross-traffic alert, a reversing camera, a 360-degree camera view, tyre pressure monitoring, front and rear parking sensors and more. 

If, despite all that, a crash is unavoidable the airbag count runs to 10 - dual front, front side, rear side, side curtain, front centre and driver's knee.

There are three top tether points for securing child seats across the second row with ISOFIX anchors on the two outer rear positions. 

That’s an impressive safety run down, as good or better than any category competitor.

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 Octavia is covered by Skoda’s seven-year/unlimited kilometre warranty, which is ahead of the mainstream five-year warranty pack, although a little short of some, like MG and Mitsubishi at 10 years.

Service is recommended every 12 months/15,000km and a four-year/60,000km service pack will set you back $2000, with 12 months’ roadside assistance topped up for another year after each trip to an authorised workshop.

That $500 per service charge is a solid amount but not outrageous for a premium, especially Euro, mid-sizer. For reference the Mazda6 20th Anniversary averages $552 per service over the same period.
