Mercedes-Benz GLB-Class vs Jeep Wrangler

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 changes to this updated Jeep Wrangler are small but meaningful. The inclusion of airbags, the updated media screen, and a feisty engine which suits the plucky nature of this off-roader make it a better Wrangler than ever.  

Note: CarsGuide attended this event as a guest of the manufacturer, with travel, accommodation and meals provided.

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 Jeep Wrangler looks like a cartoon of a four-wheel drive, that’s how familiar and well-known the design is. It’s almost generic, like the word Jeep.

You could say the design is iconic, given that the roots of this SUV stretch back to the little Willys off-roader built for the US army in World War II. And to this day the slotted grille, pronounced wheel guards, short and upright windscreen, even the removable doors are still with us in this latest incarnation.

That’s why each generation of the Wrangler only sees very subtle tweaks to famous shape and look, in much the same way a Porsche 911’s design changes at the rate of dripping water reshaping a rock.

Changing the styling completely would destroy the look which connects the Wrangler to its past and the nostalgic appeal would be over. 

So, this update sees more than subtle styling changes in the form of a tweak to the grille with the addition of a metallic-look trim around each of the slots while the mesh insert now has larger openings.   

Along with this there’s a new front bumper. The Wranglers we tested had the optional heavy duty steel front bumpers.

There’s also some interior changes in the form of a new dashboard trim, horizontal air vents and then there’s the 12.3-inch media display which goes a long way to making the cabin look more modern.

Still, the interior is busy with buttons and switches in a design that seems to mix the look of heavy machinery controls with a prestige car. The Nappa leather of the Rubicon grade lifts the quality feel higher.

All Wrangler interiors also have an internal roll-over cage which covers the entire cabin, for the fixed metal roof and removable roof body style which are standard on the Overland and Rubicon.

Only the Rubicon is offered in a two-door and a four-door, while the Overland and Sport S are four-door only.

The Rubicon two-door looks cute and fun to my eyes, while the four-door versions look a bit more serious and beefy, but both definitely still give off tough and adventurous vibes.

The wheelbase difference between the two is as giant as it looks. The Rubicon two-door’s wheelbase is 2459mm while the four-door Rubicon’s, along with the Sport S and Overland, is 3008mm.

The Wrangler ranges in length from 4334mm for the Rubicon two-door to 4882mm for the four-door Wranglers. Width is the same for all Wranglers at 1894mm and the height ranges from 1879mm in the Rubicon two-door to 1901mm in the four-door versions.

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.
 

When we review most SUVs practicality is scored on things like legroom, storage space and boot size. But in the case of a vehicle with removable doors and roof, and a cabin that has one-way drainage valves so you can hose the interior out, practicality takes on a different meaning.

The Wrangler’s practicality seems focussed on serving adventurous folks in search of a muddy off-road expedition and, so, while there is storage it’s mainly nets for door pockets, moulded wells on top of the dash, and smaller hidey holes to makes sure loose items don’t get flung around the cabin.

Given the roof can be removed there’s also a lockable glove box and centre console storage box.

When it comes to cabin space the Wrangler’s interior feels a bit cramped. The footwells up front don’t offer much space and headroom throughout is restricted by the roll cage which stretches from the front to the boot.

The four-door Wrangler has five seats and good legroom in the second row, even for me at 189cm tall. As mentioned above, headroom is limited in places because of the safety structure. Boot space behind those rear seats is 898 litres.

The two-door Rubicon has four seats. The back ones aren’t the most spacious and the boot behind them is almost too small to mention at 365L, Two pieces of carry-on luggage wouldn’t fit back there and we had to put our bags on the rear seats.

The rear tailgate for all Wranglers is side-hinged (opening left to right) and splits to allow just the window section or lower part to open separately.

For charging and powering devices all Wranglers have two USB ports up front (one -A and one -C) and four USB ports in the second row (two -A and two -C). There are also two 12V outlets on board (front and rear).  

There are two cupholders, seatback map nets and directional air vents for the second row.

The Wrangler sits high and climbing into the rear seats might be a challenge for smaller kids or even fully-grown humans, but there are chunky handholds at the pillars for extra help.

So, the Wrangler has excellent practicality, but this is geared more to its intended purpose of adventuring off-road rather than the city commute and school pick-up.

The Jeep Wrangler range comes in three grades. There’s the entry-grade Sport S which can only be had with four doors, the Overland which is also a four-door and the top-of-the-range Rubicon comes as a shorter wheelbase two-door and the four-door. 

The Sport S replaces the Night Eagle as the entry-point into the Wrangler range and with a list price of $75,950 it’s $5500 cheaper, too. 

Above this is the Overland for $84,950 and at the top of the line-up is the hardcore Rubicon which is $83,950 for the two-door and $90,450 for the four-door.

This update sees all Wranglers now coming with a (damage and scratch-resistant) 'Gorilla Glass' windscreen and a 12.3-inch media screen. But each grade also comes with its own new features. 

The Sport S has been given heated front seats, a heated steering wheel and ambient cabin lighting. Meanwhile, the Overland now has power front premium 'McKinley' seats and soft spare tyre cover.

And finally the range-topping Rubicon receives Nappa leather seats and a forward-facing 'Trailcam'.

There are mechanical upgrades across the range, too, especially for the Rubicon and we’ll get to those in the engine and driving sections of this review.

As for the rest of the features, coming standard on the Sport S are LED headlights, 17-inch alloy wheels, proximity key and push button start, sat nav, Apple CarPlay and Android Auto, a nine-speaker Alpine sound system and dark tint windows.

Along with its new features the Overland also comes standard with all of the Sport S’s equipment plus a three-piece removable hardtop, 18-inch wheels and a leather-wrapped shifting knob and hand brake handle.

Then there’s the Rubicon which has all the Sport S features, but 17-inch wheels instead of the 18s and an enormous amount of engineering hardware that makes this grade the off-road king of the Wranglers, which we’ll get to.

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.

One of the biggest changes Jeep could make to the Wrangler without causing complete mayhem for fans is to the engine and even then there will be folks who don’t like what they’re about to read.

Deep breaths, okay? Right, so, in this update the V6 petrol engine has been replaced by a 2.0-litre turbo-petrol four-cylinder. 

At 200kW the new four-cylinder makes a smidge less power than the V6 but more torque at 400Nm. An eight-speed automatic transmission shifts gears and sends the drive to all four wheels.

If you’re a Wrangler fan you’ll most likely know about this engine swap, but you’re wondering how this four-cylinder feels.

The answer is, really good. Jeep has got it right. It’s a torquey, responsive engine that feels energetic and suits the Wrangler's personality well.

In the short time I’ve spent on and off the road I’m convinced this turbo-four will be a good companion wherever you decide to go.

And go pretty much anywhere you can, with all Wranglers being ridiculously capable off-road thanks to their ladder frame chassis, high- and low-range gears, outstanding ground clearance (233mm-257mm, depending on variant ), excellent approach angle (41.4 to 44 degrees, depending on variant) and a departure angle to match (37 degrees for the both Rubicons; 36.1 for the Sport S and Overland).  

The Rubicon comes standard with Jeep’s 'Rock-Trac' on-demand four-wheel drive system and this update adds a full float rear axle. Sport S and Overland grades have Jeep’s 'Selec-Trac Active' on-demand 4WD set-up.

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 new turbo-petrol, four-cylinder means better fuel economy than the V6 it replaces. We have yet to test Jeep’s claims that after a combination of open and urban roads the four cylinder uses 9.2L/100km in the sport S and Overland grades and 9.9L/100km in the Rubicon.

In comparison, Jeep says the previous V6 uses 10.1L/100km in the Rubicon and 9.9L/100km in the Overland. Our own testing saw consumption closer to 13L/100km.

We’ll have the new Wrangler in our garage soon and we’ll be able to put the fuel consumption claims to a real world test.

In terms of range, the two-door Rubicon has a 61-litre fuel tank and in theory a range of up to 680km. The Sport S and Overland have an 81-litre tank and can get up to 880km, while the four-door Rubicon’s 81-litre tank should manage 830km.

Of course if you’re off-roading you’ll use more fuel and the range will drop accordingly.

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.

Every one of the Jeep launches I’ve attended over the past 15 years has involved a pretty decent off-road component and it’s clear the company has a lot of faith in its product.

This Wrangler launch’s off-road test had been scaled back due to days of flooding rain beforehand, but the section that was passable was enough to remind us of what we already know and that is the Wrangler is formidable.

A Queensland bush off-road course full of steep, muddy hills, ruts, rocks, dirt and slippery descents was still all there for us to test the Wrangler Rubicon four-door.

Fun and comfortable are the first words that pop into my head when recalling how the Rubicon fares. This is a super-capable beastie that feels planted, secure and adept at all times.

We tested low- and high-range four-wheel drive, locked the rear differential and let the hill descent mode do its thing and get us down the sides of hills that felt so close to vertical all we could see through the windscreen was the ground.

What's also clear is the new turbo-petrol, four-cylinder feels well suited to the job, with plenty of torque along with a feisty and responsive nature that fits the Wrangler better than the old V6.

There was also plenty of time spent on the road in the four-door Rubicon and its smaller two-door sibling. And was here it was also super clear the Wrangler felt like we’d taken it out of its natural habitat.

At 110km/h on the motorway the two door Rubicon feels light and floaty in its suspension, with steering adjustments having to be made constantly, like actors pretending to drive cars in movies, as the Wrangler wanders around in its lane. The Wrangler wander is a known trait and isn’t specific to this updated car. 

And even though our launch drive took us on some great winding country roads which would have been perfect for a Mazda MX-5, the Wranglers found the fast tight turns difficult to handle.

I’m sure I heard a sigh of relief from our Rubicon as we pulled off the road and selected low-range four-wheel drive before bouncing up what looked to be a sheer cliff, with ease.  

Of course, our Adventure Expert Marcus 'Crafty' Craft will put the Wrangler though its paces once we have one in the CarsGuide garage.

The Jeep Wrangler has a three-out-of-five star ANCAP rating from testing in 2019. This isn’t an adequate safety score for a modern vehicle and the relatively modest advanced safety tech compared to other new SUVs and its structural integrity in crash tests caused ANCAP enough concern to award it lower scores.

Surprisingly the ANCAP report scored its child occupant protection at 80 per cent which is excellent.

This update to the Wrangler now adds curtain airbags which cover the front and second rows. Along with these there are dual front airbags plus safety tech which includes AEB (city and inter-urban) and blind spot warning. There’s also adaptive cruise control and front and rear parking sensors.

For child seats you’ll find two ISOFIX and three top tether mounts across the second row of the four-door variants.

The standard full-sized spare wheel is mounted on the tailgate. 

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 Wrangler is covered by Jeep's five-year/100,000km warranty, which is off the mainstream market standard of five years/unlimited km.

Service intervals are recommended every 12 months and 12,000km and service prices are capped at $399. Jeep also offers lifetime roadside assistance if you service your Wrangler though Jeep.
