Mercedes-Benz S400 vs Skoda Karoq

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.

This new entry-level Karoq gives the already accomplished mid-size SUV an even sharper value-for-money edge. On top of that it's space efficient, hugely practical and economical. Safety's up to speed, the ownership package is solid and it's a quiet, refined drive. Before joining the RAV4 queue, we'd suggest giving this Skoda some serious thought.

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

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.

Skoda's distinctively broad, vertically slatted grille stands the brand apart, and even after six years in market the Karoq looks crisp and contemporary with chiselled character lines and jagged head and tail-lights blending successfully with more gently curved surfaces along the car's flanks and turret.

It might be a subconscious side-effect of knowing Skoda is part of the VW Group, but I can't help seeing hints of Tiguan here and there, particularly around the side windows and rear end.

But cool touches like aero-influenced inserts in the 18-inch alloy rims reinforce the Karoq's individual look.

Move to the inside and while the 8.0-inch central media touchscreen and 8.0-inch digital instrument display are on the pace the overall design shows the car's age.

Quality trim materials lift the tone, the cloth seats with contrast stitching look (and feel) great, but the understated dash design in particular is 'traditional', the vibe accentuated by liberal use of piano black highlight elements.

That said, the mix of on-screen functions and physical controls works well ergonomically and the leather-trimmed, partially-perforated, flat-bottom steering wheel is hard to fault.

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.

In terms of dimensions, at just under 4.4m long, a bit more than 1.8m wide and a fraction over 1.6m tall the Karoq is a relatively small medium SUV.

Yet, its 2638mm wheelbase means there's enough space between the axles for generous accommodation front and rear with enough room left over for a decent boot.

There's ample room for me, at 183cm, in the front with plenty of breathing space between driver and co-pilot. Not to mention heaps of storage including big door bins with room for large bottles, an open area in the centre console under an extending and height-adjustable centre armrest, various coin and oddments slots, a good size glove box, a broad lidded dash-top compartment and a drop down box near the driver's right knee.

Move to the rear, and sitting behind the driver's seat set to my position, I've got good head, leg and shoulder room. Best for two adults, although three would be possible for (cozy) short trips.

Three up to teenage kids will be fine back there, but if your kids are in a capsule, child seat or booster you'll be good with two but three will be a bridge too far.

Again there are door bins with enough room for oversize bottles, three cupholders in the fold-down centre armrest (one is 'venti'-sized) as well an oddments tray at the back of the front centre console and map pockets on the front seat backs. Adjustable ventilation is another plus.

With all seats up the Karoq offers a healthy 588 litres (VDA) of storage space, expanding to 1810L with the 60/40 split rear seat folded. A rear seat 'ski-port' style door also increases flexibility.

There are numerous bag and tie-down hooks as well as thoughtful storage spaces around the boot space. A full-size (speed limited) spare sits under the floor and while the tailgate misses out on power assistance, there's a typically useful dangling grab handle to help with closing.

For those keen on towing the FWD Karoq is rated up to a 1.5-tonne braked trailer (750kg unbraked).

To tempt people away from the Toyota RAV4 juggernaut you need a distinctive brand personality, which the Karoq has in spades, as well as a standard features list long enough to entice but not so lengthy that it sends the asking price over the top.

And this new Karoq entry-grade model is set at $39,990, drive-away, which is a shot across the bow of the base RAV4 GX 2WD sitting at $39,760, before on-road costs.

It's also in the same ballpark as the X-Trail ST five-seat 2WD ($37,250 before on-roads) and Outlander ES five-seat 2WD ($37,740 BOC).

So, the balancing act between price and equipment lands with standard feature highlights including dual-zone climate control, adaptive cruise control, 18-inch alloy rims, auto LED headlights, an 8.0-inch multimedia touchscreen, wireless Android Auto and Apple CarPlay, a reversing camera, built-in nav and eight-speaker audio.

That's pretty handy, although it's worth noting while the start is keyless, entry to the car isn't, and while the Karoq Style and SportLine boast an auto tailgate, this grade misses out.

Clearly, there's been careful fine-tuning of the value equation but the car maintains a premium look and feel that stacks up well in the segment.

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.

The Karoq is powered by a 1.4-litre, all-alloy, direct-injected, turbo-petrol four-cylinder engine sending 110kW (at 6000rpm) and 250Nm (from 1500-3500rpm) to the front wheels via an eight-speed automatic transmission.

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.

Skoda's official combined cycle fuel economy number for the Karoq is 6.5L/100km, the 1.4-litre turbo-petrol engine emitting 147g/km of CO2 in the process.

On the launch drive program for this new entry-level model, covering city, B-road and freeway running along the coast south of Sydney, NSW, we recorded an average of 7.6L/100km.

That's useful for a conventional combustion engine without the benefit of electric hybrid assistance. Worth noting, however, minimum fuel requirement is the pricier 95 RON premium unleaded.

You'll need 50 litres of it to fill the tank which equates to a theoretical driving range of 770km using the official figure or around 660km using our on-test result.

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.

Despite riding on sizeable 18-inch alloys (shod with 215/50 Goodyear Eagle F1 rubber), first impressions behind the Karoq's wheel are dominated by how composed and refined it is.

Even on coarse, irregular B-roads the car remains supple yet balanced and well buttoned down in the corners. The steering is nicely weighted and road feel is good.

Skoda says the Karoq will accelerate from 0-100km/h in 9.2 seconds, which isn't ferociously fast but the 1.4-litre turbo four delivers its peak pulling power from 1500-3500rpm, which means you're never short of mid-range urge.

The smooth eight-speed auto also helps keep things on the boil although power delivery isn't always linear. Squeeze the throttle and the engine can take half a beat before responding in something of a rush.

Shift from 'Normal' to 'Sport' mode and the transmission will respond more urgently, holding on to ratios longer and changing down more readily. And if you want full control, move the lever over into the 'Tiptronic' manual position for satisfyingly rapid changes on-demand.

The engine remains quiet, only making its presence felt at higher revs, the supportive front seats remain comfortable over lengthy stints and the brakes (vented discs front, solid rotors rear) deliver firm, progressive stopping power even under the pressure of an enthusiastic twisty backroad run.

Under the heading of miscellaneous observations, the multimedia system is easy to navigate and quick to respond, the extending, height-adjustable front centre armrest is brilliant and the adaptive cruise system responds to changes quickly yet calmly.

The Skoda Karoq's previous five-out-of-five ANCAP star rating has timed out, given the assessment was from 2017, so it's now unrated.

But that doesn't mean it's underdone in terms of active crash-avoidance tech, this base version featuring AEB (operational from 4.0-250km/h) with pedestrian and cyclist detection, adaptive cruise control, 'Lane Assist', 'Side Assist' (with rear cross-traffic alert), Parking Distance Control (front and rear), a reversing camera, rear AEB as well as tyre-pressure and fatigue monitoring.

If a crash is unavoidable, there are seven airbags on-board - dual front, front side, full-length side curtain and a driver's knee bag.

Multi-collision brake minimises the chances of subsequent collisions following an initial impact and there are three top tethers and two ISOFIX anchors for baby capsules and/or child seats across the second row.

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.

Skoda is ahead of the mainstream pack, offering a seven-year, unlimited kilometre warranty, which is two years up on the majority of the Karoq's competitors.

Roadside Assist is complimentary for the first year, renewed annually if you have your Karoq serviced at an authorised Skoda dealer.

The main service interval is 12 months/15,000km, which is in line with most of the competition, and Skoda offers a seven-year service pack for $2750, or $393 per workshop visit, which is competitive with much of the segment but some way off the Toyota RAV4 non-hybrid at $215 per service on a capped-price deal.

On top of that, through Skoda Choice you can opt for a Guaranteed Future Value offer ranging up to five years, with variable deposit and finance currently at a 6.99 per cent rate.

At the end of the term you can trade-in for a new Skoda, pay out the balloon amount and keep the car or simply hand it back.
