Mercedes-Benz S400 vs Lotus Emira

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.

If this really is the final petrol-powered Lotus sports car then it’s a sad day for fans of the brand and its history. But it’s also worthy of celebration because they have made a car that is genuinely impressive.

It may not be perfect, and it will have to fight hard to lure buyers away from Porsche, BMW and co. but for anyone who enjoys a dynamic, engaging and incredibly fun sports car the Emira should be on your short-list.

Alternatively, if you’ve always dreamed of buying a traditional Lotus sports car and haven’t got around to it until now, this is your last chance so don’t wait too long.

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.

As mentioned earlier, the Emira is meant to be a bridge between Lotus’ past and its future - combining elements of its previous sports cars while also laying the visual tone for future models.

The design does a good job of that, because there’s clearly a link to the Exige and Evora of the recent past, but it also takes heavy influence from the limited-run Evija hypercar.

In turn, this new design language will spread out across the all-new electric models, including the Eletre SUV and Emeya sports sedan.

The styling does a good job of making the Emira look and feel like a premium sports car, without the need for any flashy wings or similar. It’s a simple, compact but stylish sports car.

This trend carries over to the cabin, with the more premium finish with the carpets, leather and good quality switchgear, as well as the digital instrument display and 10.2-inch multimedia touchscreen. Gone are the days of a Lotus having a minimalist, exposed aluminium interior with only the bare necessities. This is a proper premium sports car.

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.

While it’s a more luxurious Lotus, it remains a compact and impractical sports car - and that’s very much on brand. In terms of storage inside the cabin, there are two cupholders and a small lidded console box, but the size of the cabin means everything is quite narrow and feels a little tight for space.

There is a decent sized, although not very deep, shelf behind the seats, so you can put smaller, softer items there and hope they don’t slide around too much.

In terms of actual luggage space, there isn’t much. There’s a small boot behind the engine, and while deep, it’s pretty narrow so you’ll only get soft bags in there if you plan on taking your Emira on a road trip.

In terms of size and price, the Emira lines up almost directly against the Porsche 718 Cayman, which is a formidable adversary, but also the likes of the BMW M4. Notably, it’s significantly cheaper than anything offered by the likes of Ferrari, Maserati and McLaren.

The MY24 Emira range begins at $155,900, before on-road costs, for the entry-level model but stretches up to just over $206,000 for the i4 First Edition we’re driving here.

The Emira has been designed as a more premium and luxurious sports car compared to the stripped down and basic models of the recent past, such as the Elise and Exige, so it gets a range of items not previously seen on many Lotus models - such as carpeted floors and the choice of either Nappa leather or Alcantara trim.

Also included are LED headlights, climate control, keyless ignition, cruise control, rear parking sensors, a premium sound system and a 12.3-inch digital dashboard.

It's worth noting the MY25 Emira line-up was detailed earlier this month. You can read all about it, including pricing and specification, here.

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 MY24 Emria first arrived in Australia with the same Toyota-built 3.5-litre V6 engine Lotus had used in recent years in the likes of the Exige and Evora. However, this new AMG-built four-cylinder provides a fresh choice.

Importantly, while built by Mercedes-AMG, the tuning and calibration is unique to Lotus (but we’ll discuss that in detail later).

That means the 2.0-litre unit is tuned to make 268kW/430Nm, which is less potent than AMG offers in its 310kW/500Nm A45 hot hatch, although a more potent version of the four-pot Emira has been confirmed for MY25.

The engine is paired with an eight-speed dual-clutch auto transmission, which you can either leave in automatic mode or change gear manually using the F1-style paddles on the steering wheel.

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.

Given the Emira is a sports car, the four-cylinder turbo is tuned for performance over economy and that’s reflected in an 10.1L/100km return on the combined (urban/extra-urban) cycle. That’s not too bad for a sports car, but is relatively thirsty given the engine capacity and the overall size of the car.

The Emira is equipped with a 60-litre fuel tank, so it has a driving range of approximately 594km.

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.

Just to be clear right up front, the score for this section is heavily biased towards the car's dynamic attributes, because frankly the Emira can be hard to live with at times.

At urban speeds the powertrain feels like a dog straining at its leash, which can result in some awkward moments.

For example, there were multiple instances where the gearbox refused to change out of second gear when exiting a roundabout, letting the engine rev quite hard and likely annoying my neighbours.

Some of the gear changes can be clunky too, not slotting as sweetly as they should on a sports car costing in excess of $200K.

However, you forget all that when you get the Emira onto a stretch of twisty, winding open road (preferably smooth tarmac) and move it from the 'Tour' to 'Sports' mode. The car comes alive, revving hard, shifting with precision and feeling like a puppy running through a field in pure ecstasy.

Like the great cars to come before it from Lotus, the Emira is in its element carving through corners. The steering is incredibly accurate, direct and responsive - as good as any sports car I’ve driven in recent memory. The chassis responds to those inputs with immediacy, too, feeling nimble, agile and engaging.

This is Lotus at its best.

Sports cars are not typically beacons of safety, not that they’re dangerous but the priority is speed, not complex and often weighty safety technology. It’s part of the reason these types of cars are rarely crash tested by the authorities, as is the case of the Emira.

But this more modern and luxury focused Lotus comes with a raft of safety items including adaptive cruise control, an anti-collision system (Lotus-speak for AEB), fatigue alert, road sign information, a vehicle speed limiter, lane departure warning, rear cross-traffic alert and lane change assist.

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.

Lotus Australia offers a three year warranty, which is in line with Porsche's cover, so that’s competitive in the sports car market. 

However, the brand does not offer capped price servicing, so you’ll need to discuss with your local dealer how much regular maintenance will cost you. The service intervals are every 12 months/15,000km.
