Aston Martin DB12 vs Mercedes-Benz S400

What's the difference?

Typically when a car company makes a bold claim in their press release it's hyperbole designed simply to grab attention. But in the case of the DB12, Aston Martin truly has built something different than before, elevating it beyond its previous ‘Grand Tourer’ status.

While ‘Super Tourer’ may be a bit dramatic in name, this is a very impressive car across the board. It’s fast, fun, luxurious, comfortable, opulent, stylish and liveable, so while it may require a heavy financial investment, you are duly rewarded.

Plus you also get to pretend to be James Bond…

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.

Personally, I felt like Aston Martin peaked with its ‘DB’ design nearly two decades ago with the DB9. It was a masterpiece of simplicity, elegance and heritage and the subsequent DB11 just looked more fussy and complicated for the sake of being different.

The DB12 manages to correct that mis-step from the designers, getting back to the classic silhouette of an Aston Martin, maintaining the trademark elements (specifically the unique grille shape) and the elegance of simplicity.

Aston Martins don’t need to be attention-grabbing like a Ferrari or Lamborghini. Instead, they attract attention with an understated but unmissable presence that just attracts eyeballs. You don’t need to know anything about cars to know that the DB12 is a very expensive, luxury sports coupe - it says all that the second you get a look at it.

The interior of DB12 looks and feels every bit as prestigious as the exterior does. High-quality materials have been used throughout and there is a level of fit and finish that elevates beyond most other cars on the market. It feels like a hand-made car, built with patience and detail, rather than something rushed down a production line.

The cabin design itself manages to feel both classical and modern, in the same way the exterior takes inspiration from Aston Martins of previous years but gives them a 21st century update.

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.

Inside Aston Martin’s designers have understood the typical customer isn’t a Gen Alpha who does everything on their smartphone, so there’s a neat array of proper buttons, switches and dials to take care of all the functions without taking your eyes off the road. If you are into technology you may be disappointed by the relatively small infotainment screen, but from a usability perspective it does the job well.

As you’d expect the level of fit and finish is impressive and the diamond quilting on the leather seats looks exceptional. The seats themselves are comfortable and supportive, with generous cushioning rather than the sportier, less comfortable seats found in purebred sports cars.

The DB12 is a 2+2, with a pair of seats in the rear, but to be frank you’d need to be desperate to use them. They are ‘emergency use only’ seats that will deeply compromise the front seat occupants just to squeeze anyone in the back.

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.

If you can call a car that starts near two-hundred grand good value, then you have much more money than I do. But there is no escaping it: the new S-Class 2018 range is better value than before.

The starting point in the range is entry-grade S 350 d, which is $195,900 plus on-road costs. 

Standard kit for that model includes 19-inch alloy wheels, leather trim, heated and cooled front seats, nappa leather-wrapped steering wheel, those great new headlights and the new ambient lighting system, a panoramic sunroof, head-up display, dark brown 'Eucalyptus' trim, auto-dimming rear-view and side mirrors, a wireless phone charging system, keyless entry and push-button start. The entire S-Class range now gets auto-closing doors and an electric boot lid, too.

The media system in the S 350 d includes sat nav with traffic monitoring, a 13-speaker Burmester sound system, digital TV, DAB+ digital radio, Apple CarPlay and Android Auto, and the 'Comand Online' system with internet capability.

Next up the model range is the S 400d L (at $222,500), and the S 450 L ($227,500) - both of which are specified identically. Over the base model car they feature the extended wheelbase, as well as electronically adjustable rear seats with memory function, side window blinds, a rear blind, rear climate control, and 20-inch wheels. 

The S 560 sees the price head north to $270,000 (for the short-wheelbase model, which loses the abovementioned stuff in the L models), or $295,000 for the S 560 L. It adds the following nice features: nappa leather, brown burr walnut trim, a wood/leather steering wheel, 'Energizing Comfort Control', different (five-spoke design) 20-inch wheels, laminated glass and an anti-theft protection package. The S 560 L has luxury rear head restraints - they’re more like pillows, honestly - an individual rear-seat entertainment system and two wireless headsets.

The top of the regular S-Class model range is the Mercedes-AMG S 63 L, which is a princely $375,000. It builds on the kit offered in the models below, and pushes the sports luxury aspect further, with a full AMG body kit, 20-inch AMG wheels, AMG specific drive programs, AMG brakes, an uprated exhaust, sports steering and retuned suspension. Inside there are model-specific elements, special wood trim, front seats with active bolstering, and heated and ventilated rear seats.  

If you’re shopping at this end of the market, then you’ll likely also be tossing up between a BMW 7 Series, or maybe a Bentley Flying Spur. An all-new Lexus LS will arrive in April 2018, and the all-new Audi A8 isn’t far away, either.

Aston Martin was once famous for its V12 engines, but with the brand changing hands so many times over the years and the pressure to develop increasingly expensive powerful, yet fuel-efficient engines means the brand now outsources some of its powertrains. So while the brand is developing a new V12 engine, the DB12 is powered by the 4.0-litre twin-turbo V8 built by Mercedes-AMG.

While Aston Martin fans may bemoan the use of a German engine in this British car, the truth is it’s a much better engine than the previous V12 used in the DB11, Vantage and other models. It offers up 500kW/800Nm and delivers all that performance in a broad spread across the rev range (unlike the old V12).

It gives the DB12 a sportier, more urgent and responsive driving character than its predecessors and helps to explain the new ‘Super Tourer’ name. Aston Martin claims it can run 0-100km/h in just 3.6 seconds and has a top speed of 325km/h.

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.

Aston Martin claims a combined fuel cycle return of 12.2 litres per 100km, which is not what you would call sipping the unleaded, but given this is a large, grand tourer (sorry, Aston Martin, Super Tourer) it’s actually a solid return. If you’re in the market for a car like this, anything sub 15L/100km should be considered acceptable; if you’re worrying about emissions or the cost of petrol you probably shouldn’t be buying a $455k sports car.

Unfortunately we didn’t have the DB12 long enough to get a real-world fuel economy figure, so we’ll just have to take Aston Martin’s word for it.

With its 78-litre tank the DB12 does have a theoretical driving range of approximately 630km.

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.

The defining characteristic of a ‘Grand Tourer’ is that while fast, they aren’t typically agile and as responsive as a sports car. In other words, a grand tourer is best suited to a long, cross-country trip on faster, flowing roads, rather than a winding mountain pass or twisty switchbacks.

So, in keeping with the ‘Super Tourer’ theme that the brand is selling, the DB12 is notably more responsive and therefore more engaging to drive across any condition. It still has the comfortable, laid-back nature of a ‘GT’ but when you want to have some fun it’s capable of hiding its size and feeling very sporty.

The handling is highlighted by how quickly the front end of the car reacts. Typically with this front-engined 'GT' cars you feel like you're sitting at the very back of the car, so it feels slow to respond to inputs and that can create a feeling of laziness. But not in the DB12. The front end feels sharp and responsive, making you feel like you are right at the centre of the action.

It's helped by the engine that feels lighter than the old V12s but more urgent with its power delivery, too. It adds to that feeling of a more sporty and focused driver's car, rather than a 'GT' for just soaking up the kays. It shouldn't be surprising though, AMG doesn't really build relaxed, laid-back engines, rather ones designed for maximum excitement - and that's what the DB12 delivers when you bury your right foot.

Remarkably, it also plays the role of ‘daily driver’ well too. Which is an unusual way to think of a car like this, but for those fortunate enough to have the means to afford it, the DB12 could ferry you from home to work and back again in luxury and comfort.

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.

Easily one of the safest cars, if not the safest car, on the road today if technology is anything to go by. Well, we can’t go by a crash test score, because the S-Class hasn’t been crashed by EuroNCAP or ANCAP. So I can’t really give it a 10/10 for safety…

But when the standard safety kit list is as lengthy as the S-Class’s, it seems a safe bet. Items fitted include a 360-degree camera system, parking sensors front and rear, auto emergency braking, active blind-spot monitoring, active lane-keeping assist, adaptive cruise control with active steering assist, drowsiness detection, crosswind assist, and pedestrian detection with evasive steering assist (which allows you to turn the wheel harder to avoid impact with a pedestrian).

Plus there are other items like the company’s Pre-Safe crash detection system which can flash the car’s hazard lights at other road users, and tighten the occupant’s seatbelt in anticipation of being hit. And if that happens, there are eight airbags (dual front, front side, rear side, curtain).

The standard Aston Martin warranty covers three years/unlimited kilometres, which is unusually short by current industry standards; a curious case of the top end of the market lagging behind the mainstream brands.

Servicing is handled by individual dealers, so there’s no set cost structure, but the intervals are every 12 months/16,000km. Instead you’ll need to discuss what sort of costs are involved with keeping your DB12 running smoothly when you speak to a salesperson.

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.
