Chrysler 300 vs Mercedes-Benz GLB

What's the difference?

The Chrysler 300 SRT is a big, fast, well-equipped and super-comfortable point-to-point tourer that’s also able to soak up the stresses of a city commute with ease. It’s also showing its age in terms of design, obscenely thirsty, dynamically flawed, and offered with a bottom-of-the-class ownership package. A fun place to visit but make sure you’re ready for permanent residency.

The Mercedes-Benz GLB is an oddball. While it isn’t my definition of beauty, it's a surprisingly capable and spacious small-to-medium SUV.

The entry-level GLB200, while comfortable, feels a bit underdone in the engine department. Therefore the mid-spec GLB250 with the more-powerful 2.0-litre turbo and mild-hybrid assistance plus all-wheel drive grip is the better pick.

The NSW Highway Patrol has adopted the 300 SRT as its weapon of choice, and psychologically I reckon they’re onto a winner.

A high waistline, small glasshouse and big 20-inch rims combine to give the 300 a chunky, take-no-prisoners stance. And this intimidating beast filling the mirrors is enough to make even the most determined speedster drop their bundle.

Except for the SRT badge at the back, the exterior is a chrome-free zone, with black finish on the big honeycomb grille, window frames, and dark chrome wheels dialing up the overall air of menace.

The rear view is similarly imposing, with a large slab of almost right-angular boot lid topped by a pronounced body-colour spoiler.

At this point, we have to call out less than perfect panel fit. On our test car for example the intersection of the bonnet and front clip above the headlights was messy with inconsistent shut lines and poor alignment.

Inside not much has changed over the current 300’s seven years on sale, and the design lacks the integrated approach of more modern competitors.

An 8.4-inch colour media touchscreen sits in the centre of a squared oval panel between the central air vents and under an analogue clock, that shape bearing no resemblance to the form of the heating and ventilation control panel below it or the instrument binnacle alongside.

A mass of buttons confronts the driver across the centre stack, steering wheel and door, while genuine carbon fibre inserts add a racy if slightly ironic touch in a close to 2.0-tonne car.

Leather and suede sports front seats look (and feel) the business, and the strongly illuminated gauges are divided by a 7.0-inch multifunction display including a clear digital speed read-out. Which is just as well, because the fussy increments on the analogue dial are hard to read.

This isn’t the prettiest car ever. It has the Mazda CX-8 or CX-80 effect where you can tell a smaller car has been stretched and extended to create more interior space. It just looks a little awkward as a result.

The rear section of the GLB in particular is much higher and boxier than the GLA which makes it look rather back-heavy. Thankfully roof rails are standard which toughens the look somewhat.

The facelift that was introduced in 2023 brought an updated front bumper, as well as tweaked LED headlight and tail-light signatures. The changes aren’t wildly different from the original car that launched in 2019 but it’s still fresh enough.

Inside is where this car is starting to look its age. While Mercedes-Benz was one of the first to introduce a wraparound screen set-up combining the digital instrument cluster and touchscreen multimedia system into a single unit, many have copied this and it no longer looks unique.

It doesn’t help that the dual 10.25-inch screens are small now in comparison to newer rivals. It’s standard for a digital instrument cluster to be closer to 12.3-inches in diameter now.

A main interior change with this facelift included the removal of the touchpad controller on the centre console. In its place is now a shallow storage area which doesn’t really serve a purpose.

There’s also a new AMG-style steering wheel as standard which has fiddly gloss black touch sliders that get grimy upon use.

While the changes are welcome, the ageing roots are still present. You can’t escape the blingy touches that just end up looking cheap and tacky.

A key example of this are the air vents which have obnoxious interior ambient lighting in them to try and make the cabin look cool.

I’m also not a huge fan of the star pattern trim on the dashboard and the swathes of stainless steel-looking inlays.

At just under 5.1m long, 1.9m wide and close to 1.5m tall the 300 SRT is a sizeable machine, so it’s no surprise there’s plenty of room inside.

Those up front are provided with a pair of cupholders in the centre console (complete with heating or cooling at the press of a button), storage bins and medium-size bottle holders in the doors, a long oddments tray and a small storage cubby (with 12-volt outlet) near the gear shifter, as well as a sunglasses holder in the overhead console and a big glove box.

There’s also a lidded storage box between the seats, complete with sliding tray, two USB ports, an ‘aux-in’ jack and a 12-volt outlet. Even old school nicotine enthusiasts are catered for with an ashtray insert ready to slip into one of the cupholders and a cigarette lighter to drop into the main 12-volt socket.

Rear seat passengers pick up a fold-down centre armrest with two cupholders and a lidded oddments box, decent door bins with bottle holders, as well adjustable vents at the back of the centre console, two USB ports, and switches for the standard heated rear seats.

Sitting behind the driver’s seat set for my 183cm position I had ample legroom but only adequate headroom. There’s enough shoulder room for three adults across the rear, but the broad transmission tunnel throws a spanner in the works when it comes to centre foot room.

The fully-lined boot is nicely trimmed, with a pair of flip-out bag hooks (22kg capacity), load tie-down anchors, and useful lighting included.

Volume is 462 litres, enough to fit our three-piece hard suitcase set (35, 68 and 105 litres) lying flat on the floor, or the CarsGuide pram, with heaps of room to spare. A 60/40 split-folding rear seat adds extra space and flexibility.

In the case of a flat tyre your only option is a repair/inflator kit, and it’s worth noting towing capacity for the SRT is the same 450kg for a braked or unbraked trailer, where the standard V6-powered 300C can tow a 1724kg braked trailer.

Up front the driver’s seat is comfortable, offering electric adjustability and lumbar support, extendable thigh support and heating. Some extra bolstering on the seat base would be nice though as it’s a little flat for my liking.

While the glossy piano black touch sliders on the steering wheel aren’t the most intuitive, I love holding this leather-wrapped wheel as it straddles the line of being thick enough but not too thick. BMW should take note…

The thin stalks behind the steering wheel are a joy to use and have a nice thwack to them. I appreciate the column-mounted gear selector as this frees up more space on the centre console, though it could be utilised better. More on this in a bit.

The digital instrument cluster offers a range of different themes to select from, though the standard version looks the nicest and offers the most customisation. It’s nice being able to put a full-width map display on the instrument cluster.

The touchscreen multimedia system offers a clean and intuitive interface that’s hard to get lost in. For the most part, however, I ended up using smartphone mirroring. Thankfully this update brought wireless Apple CarPlay and Android Auto.

It’s nice having the row of physical climate control switchgear within easy reach especially as carmakers are now integrating these into the touchscreen interface. Even Mercedes-Benz is guilty of this in its newer cars.

There isn’t a tonne of general storage on the centre console beyond the deep central box which has a split-opening lid. The wireless charger barely fits my iPhone 15 Pro Max, the cupholders are on the small side and the aforementioned storage section where the touch slider once was is useless from a storage standpoint.

Moving to the second row, it’s rather spacious for a small-ish SUV. At a leggy 182cm tall, I have plenty of leg and headroom behind my own driving position.

You’re able to slide and recline each individual seat in the second row to prioritise second-row comfort or allow more space for third-row passengers. It’s needed because third-row space is tight!

Second-row amenities include air vents mounted on the back of the centre console, various storage spaces, two USB-C ports, as well as a fold-down armrest with cupholders. Also if you stare at the back of the centre console it looks very much like a screaming face.

As already mentioned, the third row isn’t the most spacious ever, although this is a small-ish SUV so best not to expect palatial levels of room. It’s likely more for occasional use by children and it’s good to note there is airbag coverage back there.

Amenities are few and far between in the third row, limited to just a few storage spots and a USB-C port on both sides. Unfortunately there are no air vents.

At the back there’s a handsfree power tailgate which is handy if you’ve got your hands full. It opens swiftly, though with all three rows of seating upright there isn’t much room at all. Mercedes-Benz doesn’t even quote a boot capacity figure, but it’s only enough for a bag or two.

Thankfully if you’re not using the third row the benefit of this car is there’s much more boot space than the GLA. Mercedes-Benz claims there’s a generous 565L of boot space, which can further expand to 1800L with the second row folded.

Unfortunately there is no spare wheel in the GLB200 as it has run-flat tyres as standard, though regular tyres with a tyre repair kit is a no-cost option.

The Mercedes-Benz GLB200 is currently priced at $67,600 before on-road costs.

There aren’t many premium seven-seat SUVs that are this compact out there. The closest rivals would be the mid-size Volkswagen Tayron and related Skoda Kodiaq.

But for this price you can easily get something larger like a Kia Sorento, Hyundai Santa Fe or Mazda CX-80. You do have to ditch the premo badge though.

For your money you do get a generous amount of standard equipment. This includes 19-inch alloy wheels, LED headlights, dual 10.25-inch screens, wireless Apple CarPlay and Android Auto, interior ambient lighting, as well as heated front seats with electric adjustment.

However our tester was optioned with a panoramic glass sunroof ($1900) and black leather upholstery ($1539), bringing the as-tested price to $71,039 before on-road costs. This is still around $18,000 off the cheapest GLC.

A nifty reason for opting for this car over the GLA is because there’s a third row of seating. It's not the most spacious row, but when folded there is more boot space. More on this later.

Forget hybrid, forget turbos, the Chrysler 300 SRT is powered by 392 cubic-inches of Detroit iron… although the 6.4-litre ‘Apache’ V8 is actually built in Mexico.

The engine’s block is indeed cast iron although the heads are aluminium, with the ‘Hemi’ name derived from its hemispherical combustion chamber design.

It’s naturally aspirated, direct fuel-injected and produces 350kW (470hp) at 6150rpm and no less than 637Nm of torque at 4250rpm.

Drive goes through an eight-speed automatic transmission to the rear wheels with a limited-slip diff standard.

The Mercedes-Benz GLB200 is powered by a 1.3-litre turbocharged four-cylinder petrol engine which produces 120kW and 270Nm.

This engine also features in ‘200’ versions of the A-Class, CLA and GLA, plus versions of it also feature in the Renault Arkana, Captur, Duster, and Kangoo, as well as the Nissan Qashqai and now the new Mitsubishi ASX.

It’s mated to a seven-speed dual-clutch automatic transmission with drive sent to the front wheels only.

Unlike the more powerful GLB250 and AMG GLB35 all-wheel drive trims, the GLB200 is the only model to go without 48V mild-hybrid assistance in Australia. It was originally promised when this facelifted model was announced in 2023.

Mercedes-Benz claims the GLB200 can do the 0-100km/h sprint in 9.3 seconds and top speed is 207km/h.

A model of fuel efficiency this car is not. Claimed economy for the combined (ADR 81/02 - urban, extra-urban) cycle is 13.0L/100km, the 300 SRT emitting 303g/km of CO2 in the process.

Over roughly 300km of city, suburban and freeway running we recorded 18.5L/100km (at the bowser), and the on-board computer threw up some horrifying short-term numbers as we explored the car’s performance potential.

Minimum fuel requirement is 95 RON premium unleaded and you’ll need 70 litres of it to fill the tank… regularly.

Mercedes-Benz claims the GLB200 has a combined fuel consumption of 7.5L/100km.

During our urban and metropolitan-based testing, however, we saw an average of 9.0L/100km according to the trip computer which isn’t great but also not the worst I’ve seen. Expect this figure to balloon out further if you load more people onboard as the engine will have to work harder.

There is a 52L fuel tank which requires a minimum of 95 RON premium unleaded petrol.

Using my as-tested fuel consumption figure, this means the GLB200 has a theoretical range of up to 578km.

Roll onto a smooth, dry surface, engage the SRT’s standard launch control function and you’ve dialled in the ability to storm from 0-100km/h in a ludicrously rapid 4.5sec.

Unlike smaller capacity turbo engines, the big atmo Hemi takes a while to develop maximum torque (637Nm), hitting peak pulling power at 4250rpm. Keep the throttle pinned and full power (350kW) is achieved on the cusp of the rev limiter at 6150rpm.

All this fire and fury is accompanied by a beautifully brutal V8 roar courtesy of an active exhaust which tweaks the pulsing note it produces according to drive mode and throttle position. It’s hard not to love it, complete with rude pops and crackles on the over-run.

Beware though, this car is relatively loud all the time, so you’ve got to hope the love affair is a long-term one.

Suspension is by a short and long arm (SLA) and upper A-arms at the front, with a five-link set-up at the rear, and Bilstein adaptive dampers all around.

The switch between Comfort and Sport is swift and marked, with the latter best kept for billiard tables and race circuits. Around town ride in the more compliant setting is agreeably smooth.

Push the big 300 along your favourite backroad and you know you’re asking two tonnes of metal, rubber and glass to move against its will.

The eight-speed auto responds well in manual mode (with wheel-mounted paddles), and the grippy sports front seats do decent job of keeping their occupants stable and balanced, but the sheer mass of this car means you’re never going to get a corner-carving hot hatch-like experience.

And despite a chunky, leather-trimmed sports wheel, the hydraulically-assisted ‘SRT Tuned’ steering isn’t exactly the last word in road feel or sharp response.

Having said that, the fat 20-inch (245/45) Goodyear Eagle F1 rubber grips hard with minimal impact on ride quality, and in a more relaxed mode the SRT is a stress-free and comfortable tourer.

Big acceleration is balanced by big brakes, with beefy ventilated rotors (360mm fr / 350mm rr) clamped by Brembo four-piston calipers front and rear.

The system’s outright power is impressive but can be abrupt on initial application at around town speeds, until you get used to greasing the pedal pressure in.

‘SRT Performance Pages’ allows you to scroll through multiple real-time data screens (timers, G-force, engine performance, etc), which is fun, with outputs downloadable to a USB stick or SD card. The 19-speaker harman/kardon audio system absolutely cranks, and the active cruise control works intuitively, without the frustrating conservatism (taking forever to pick up the throttle) of some other systems

While this 1.3-litre turbo engine may be sufficient in the smaller A-Class and GLA, it barely scrapes by in the GLB200.

Even with one person onboard the engine has to rev out the first few gears to around 3000rpm to keep up with traffic from the lights. It doesn't have the nicest engine note either.

It doesn’t help that the dual-clutch automatic can be a little vague from a standstill, taking a beat to kick into action. This is most noticeable when doing low-speed manoeuvres or reversing.

Although initial acceleration can be on the thrashy side, rolling acceleration while at speed is a lot more linear and calm thanks to peak torque coming on tap from 2000rpm. This means the car will only downshift when it needs to.

There are a few different drive modes you can select from, but the default ‘Comfort’ mode feels the most natural. ‘Eco’ does quell some of the rev flares during initial acceleration, though the engine feels much more tardy in general.

Linked with these drive modes are the adaptive dampers. This is a very comfortable car, especially on the standard smaller 19-inch alloy wheels as there’s plenty of tyre sidewall to absorb bigger bumps.

Coupled with this is sporty steering that’s direct and makes the car feel nimble despite its 1.7-tonne kerb weight.

It really is the best of both worlds because you get the fun and sporty characteristics from the steering, plus the comfort and supple feeling from the suspension. It’s hard to fault this set-up.

In terms of noise, vibration and harshness (NVH), if you look beyond the sometimes shouty engine, this car is quiet and refined. There’s some tyre roar at higher speeds, but many European vehicles have this trait.

It’s also a benefit that this car is a little older as there aren’t many safety system-related bings and bongs that distract from the cabin ambience.

The Mercedes-Benz GLB received a five-star ANCAP safety rating based on Euro NCAP testing conducted in 2019.

It received 92 per cent in Adult Occupant Protection, 88 per cent in Child Occupant Protection, 78 per cent in Vulnerable Road User Protection and 76 per cent in Safety Assist.

As standard there are nine airbags, autonomous emergency braking (AEB), blind-spot monitoring, rear cross-traffic alert, lane-keep assist, adaptive cruise control, front and rear parking sensors, as well as a surround-view camera.

A nifty safety feature is the Pre-Safe system which tightens the seatbelts and plays a tone when it detects an imminent crash.

There are ISOFIX child seat anchor points on the outboard second-row seats, as well as on the two third-row seats. All three second-row seats, plus the two third-row seats also have top-tether points.

The warranty world has moved significantly in recent months, and the 300 SRT’s three year/100,000km warranty is now well off the pace.

Yes, it includes corrosion cover and 24-hour roadside assistance, but with the likes of Ford, Holden, Honda, Mazda, and Toyota now at five years/unlimited km, Chrysler is way behind.

Kia moved to seven years/unlimited km in 2014, and there are whispers of the Korean brand shifting to 10 years sooner rather than later.

Service is required every 12 months/12,000km, and no capped price servicing program is currently offered.

With the caveat that labour rates will inevitably vary between dealerships, Chrysler Australia estimates five year standard servicing cost at $2590 (including GST).

The GLB200 is covered by a five-year, unlimited-kilometre warranty, like the rest of the Mercedes-Benz line-up.

Logbook servicing is every 12 months or 25,000km, whichever comes first, which is good if you do a lot of driving.

You can purchase a three-, four- or five-year service package which costs $3495, $4650 and $6185, respectively. With the latter this equals $1237 per service, which is expensive, although it is cheaper than the slightly larger GLC.
