Mercedes-Benz S500 vs Chrysler 300

What's the difference?

The 2018 Mercedes-Benz S-Class remains a technological tour de force, a luxury sedan to be reckoned with - one that has safety, technology, comfort, finesse and performance all rolled into a stylish package. 

It's hard to see why you'd need anything more than the S 350 d, which is now much more attractively priced. It'd be my pick, but I'd have to get the Energizing Comfort Control package, and probably the AMG styling pack, too. And even then it would cost less than its predecessor.

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.

I swear it has been facelifted, and the changes are bigger than they might appear. There is no doubt that the S-Class shape is largely unchanged, but the German company has kept the modifications minimal in the scheme of things.

That doesn’t mean those changes are unnecessary, though. The new headlights, for example, are standard on every model, and are constructed with 84 LEDs (including three for the daytime running lights), and of course they’re adaptive with automated high-beam - meaning they’ll shield other road users from the glare of the lights at night. And the lights themselves will throw a main beam up to 650 metres, according to the company. 

Other things are slightly more cosmetic, like the revised three-bar grille treatment, new front and rear bumper designs that feature broader sculpted sections to widen the stance of the car, and there are new LED tail-lights as well.

The smallest set of wheels used to consist of 18-inch rims, but now the base car rolls on 19s, while the rest of the expansive range sits on 20s. 

The inside has seen some changes, too, but the appearance of things in the cabin isn’t the focal point - its the usability of the technology that's the big change. 

Oh, but I should tell you there are now 64 ambient lighting colours to choose from, which is up from seven, and now you can also set the lighting in three different zones - so theoretically you can have blue, orange and green areas of the cockpit, if you’re gross.

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.

If you’re buying a Mercedes-Benz S-Class there’s a good chance you’re more interested in the back seat than the front: you could be buying it for a business, or you could like to be driven around - and there are definitely worse places you could be.

We would suggest, though, that the best place you could be if that’s your caper is in the back of a long-wheelbase S-Class model, which has extra legroom. 

And if you happen to be in a LWB model with the 'Business Class Package', you’ll enjoy two individual rear seats rather than a three-seat bench, folding tables for your bento box or laptop, and an ‘executive seat’ on the passenger side that features a foot rest and allows you to slide the front seat forward to liberate more room. Deluxe. 

No matter if you are in one of the stretched models demarcated as such by the ‘L’ suffix or not, you will enjoy excellent seat comfort and good head- and shoulder-room. Legroom in the regular models isn’t as plentiful as you might expect: much more affordable cars like the Hyundai Sonata give the S-Class a run for its money in that regard.

There are good storage options for odds and ends, with the back seat featuring a fold-down armrest with pop-out cupholders and a storage box, as well as map pockets - and the boot space varies depending on the model, but the S 350 d has a 510-litre cargo capacity (VDA). All four doors have bottle holsters, and a bit of extra room besides. Of course there are rear-seat air-vents, and if you’re kids are lucky enough to ride around in a S-Class, the two ISOFIX/three top-tether points will be welcome.

Up front there are two cupholders between the seats, and a new wireless phone charger in the centre console (Qi compatible phones only). There are two USB ports as standard in most models, while models with the rear seat entertainment package fitted get rear USBs. 

The huge screen that runs across two-thirds of the dashboard has seen the noticeable join marker removed for this update, with the monitors being upgraded to a higher resolution and the graphics have been reworked, too. The codpiece-style controller of the Comand media interface remains, and while it still isn’t as simple as other controllers, it is reasonably easy to get used to. 

So … what about Beyonce? 

She comes in as part of the Energizing Comfort Control system, which is standard in some models and a $1400 option in those that don’t have it fitted. 

Essentially it allows you to choose between different set moods: 'Joy', 'Freshness', 'Vitality', 'Warmth', 'Comfort' and 'Training', the latter of which offers three different stretching/exercise programs that last for 10 minutes to stop fatigue. The instructions are given by voice over the sound system.

Each of the moods will adjust the temperature and ventilation (the Freshness setting offers ‘gusts’ of fresh air as if you’re at the beach!), ambient lighting, air fragrance and intensity, and the massage function for the seats. And the music bit - there are predefined songs the system can cue up to suit the mood, or it can identify songs on a hard-drive or USB that suit the programs by analysing the tempo of the tune. Amazing, right?

The new steering wheel looks a lot sportier than the one in the pre-update car, and it has finally done away with the awkward cruise control stalk in favour of steering wheel buttons for the adaptive cruise control system.

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.

A list price of $74,950 (before on-road costs) buys a whole lot of car, equipment, and performance, with that figure only gaining entry to a pack of next-size-down options from Europe and Japan.

A $5k spread from $71-76,000 covers the Alfa Giulia Veloce ($72,900), Audi A4 45 TFSI Quattro ($73,300), BMW330i M-Sport ($70,900), Infiniti Q50 Red Sport ($74,900), Jaguar XE P300 HSE R Dynamic ($71,940), Lexus GS300 Luxury ($75,931), and Merc C 300 ($71,800).

And aside from the extra cubic inches under the hood and sheetmetal in the body, the 300 SRT’s standard features list is long, including dual-zone climate control, keyless entry and start (plus remote start), heated and ventilated front seats, heated rear seats, heated leather-trimmed SRT flat-bottom steering wheel, heated/cooled front cupholders, power boot lid release, electric steering column adjust (height and reach), plus eight-way electrically-adjustable driver and front passenger seats (with four-way power lumbar adjust on both and radio/seat/mirror memory on the driver’s side).

Also standard are auto headlights (with auto level and auto high beam), rain-sensing wipers, power-folding exterior mirrors (with defrost), nappa leather and suede seat trim, 825-watt, 19-speaker harman/kardon audio (including digital radio), sat nav, Android Auto and Apple CarPlay, a 7.0-inch instrument cluster display, the 8.4-inch colour media touchscreen, and 20-inch forged alloy wheels.

There are plenty of other safety and performance features, which we’ll cover in later sections, wrapping into an impressive standard package at this price point. And ‘our’ test car featured the ‘SRT Luxury Package’ ($4750) adding a monster dual-pane glass sunroof, premium leather trim on the instrument panel, centre console and door trims, as well as premium floor mats front and rear.

The standard colour choice is black and white… ‘Gloss Black’ or ‘Bright White’, with ‘Silver Mist’, ‘Ceramic Grey’, ‘Granite Crystal’, ‘Maximum Steel’ and ‘Velvet Red’ optional, and ‘Ocean Blue’ available to specific customer order.

The big news for the majority of S-Class buyers is the new engine in the S 350d, which is a 2.9-litre in-line six-cylinder turbo-diesel with 210kW of power and 600Nm of torque. It has a nine-speed automatic and is rear-wheel drive (RWD).

That same diesel engine is wicked up in the S 400d L, with that model churning out 250kW and 700Nm, and remains rear-drive with a nine-speed auto.

The petrol model range is opened by the S 450 L with a 3.0-litre six-cylinder twin-turbo mill producing 270kW/520Nm. Again, nine-speed auto, RWD.

The S 560 and S 560L run the same 4.0-litre twin-turbo V8 petrol with 345kW of power and 700Nm of torque. Nine-speed auto, rear-drive - naturally!

The AMG-fettled S 63 has a thumping twin-turbo 4.0-litre V8 petrol engine with 450kW and 900Nm, with a nine-speed MCT multi-clutch auto and - you guessed it - RWD.

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 diesel models are - unsurprisingly - the most frugal in the range, with the entry-level S 350 d using a claimed 5.4 litres per 100km across a range of disciplines.

The S 400 d L - which uses a higher-output version of the same diesel drivetrain as the model above - uses only a minuscule amount more: its claim is 5.5L/100km. 

The most frugal of the petrols is the S 450 L, with its six-pot petrol twin-turbo using a claimed 8.4L/100km.

Every model has stop-start - including the AMG - and the V8 petrols also feature cylinder deactivation when in 'Eco' mode.

That cylinder deactivation system helps the S 560 achieve an incredibly low claimed consumption of 8.5L/100km. So does the longer, slightly heavier S 560 L.

The higher-out Mercedes-AMG S 63 L uses 9.0L/100km, according to its claim. Amazing for the outputs of the engine.

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.

Smooth. It wasn’t even because I’d chosen the Energizing Comfort Control mood to elicit that vibe. It’s smooth - and so it should be.

Whether it’s the near-silent new six-cylinder diesel, which hauls the near two-tonne sedan along with less fuss than a medical centre receptionist dealing with a room full of coughing patients. There is no fuss. You just hand over control to the engine, and trust it will get you where you need to be.

The V8 petrol in the S 560 also has a bit of a silent killer vibe to it. There’s perhaps not as much noise as a V8 fan might want, but the mumbo is there, and in both cars the gearshifts are sublimely timed and super smooth.

Admittedly, the stiff-sided run-flat tyres on both the 19- and 20-inch wheels can exhibit a slight terseness over sharp edges, but when it comes to rolling over pockmarked surfaces or rougher country backroads, the ride offered up by the air suspension with variable dampers is superb. Put it in Sport mode and it stiffens up to the degree you’d expect, but Comfort is no doubt the best place to be.

The steering is super light but accurate, meaning it’s easier than you’d think to pilot this behemoth of a sedan through corners. The grip on offer is excellent, too, even if traction can be an issue - I had a full couple of seconds of strobe light action from the traction control light when I buried the throttle in the S 560. 

I didn’t get a chance to drive the six-cylinder petrol S 450 L, or the S 400 d L. And, I’m really sad to report, there was no opportunity to drive the AMG S 63 L, either. 

But the overall feeling of the updated range is that it remains a deluxe and delightful limousine - whether you have the good fortune of being in the driver’s seat or not.

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

The 300 SRT hasn’t been assessed by ANCAP or Euro NCAP, but the NHTSA in North America has given the 2019 Chrysler 300 a four-star safety rating (from a possible five).

In terms of active tech a lot of major boxes are ticked, with AEB a notable exception.

Standard features include, ABS, ‘Ready Alert Braking’ (primes system when driver lifts off the brake pedal quickly), ESC, ‘Electronic Roll Mitigation’, traction control, forward collision warning, lane departure warning, blind spot monitoring, rear cross path detection, and advanced brake assist.

A ‘Rain Brake Support’ function is triggered by the rain-sensing wiper system to periodically ‘wipe off’ the brake rotors with the brake pads, keeping them as dry as possible in the wet. And Chrysler has cleverly piggy-backed ‘Knock Back Mitigation’ into the arrangement.

In aggressive cornering front wheel assemblies can flex, pushing the brake rotor against the brake pads and ‘knocking’ them back into the caliper, potentially leading to an alarmingly long pedal the next time the brakes are applied. Not a factor in the 300 SRT, with the pads automatically pushed up into their optimum position.

Also included are, adaptive cruise control (with stop function), a reverse parking camera, front & rear parking sensors, and a tyre pressure monitoring system.

If, despite all that, a crash is unavoidable, the airbag count runs to seven (dual front, dual front side, dual curtain and driver’s knee), and the front head restraints are active.

There are three child seat/baby capsule top tether points across the back seat, with ISOFIX anchors on the two outer rear positions.

Mercedes-Benz offers a standard three-year/unlimited kilometre warranty.

Servicing is due every 12 months or 25,000km on all engines except AMG drivetrains, which require servicing every year or 20,000km. 

Mercedes-Benz has a (pricey!) capped-price servicing plan. The standard diesel and petrol models in the S-Class range cost $596 for the first service, and $1192 for the second and third visits. The costs for the sole AMG model is $736 for the first service, then the second and third visits are $1472 per.

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).
