Cars are rarely as crucial to their makers or buyers as this E-Class model is to Mercedes. This full-sized Executive segment contender is the backbone of the German company's range and a perennial favourite of the corporate car park. This sixth generation 'W214'-series model retains a sensible side but dials up the desirability, aiming to offer a smarter, more prestigious approach to Executive class motoring than close competitors. It does so with more efficient engines, cutting-edge drive technology and comfort that makes you question the need for a larger luxury saloon. Arch-rivals from Audi and BMW still have quite a benchmark to aim at.

Full-Sized Executive Cars
Driving experience
Class is permanent: fame is transitory. Well this 'FAME' is anyway, the letters in this case apparently standing for 'FAmily of Modular Engines', the portfolio of four and six cylinder combustion units chosen for this sixth generation E-Class. All of which are merely transitory electrified stepping stones to the time, not far off, when EV powertrains rule all. There's no full-EV option here to rival the BMW i5 or the Audi A6 e-tron because of course the brand already has the similarly sized EQE model for that.
Instead, there's a selection of combustion powerplants defiantly still built around two formats currently falling from industry favour, diesels and PHEVs. For the time being, diesel E-Class sales are expected to continue strongly, primarily with the 194bhp 2.0-litre four cylinder E 220 d 48V mild hybrid model, which is offered in conventional rear-driven form. If you want the brand's 4MATIC AWD system (now improved), you'll need the E 450d 4MATIC, a six cylinder 3.0-litre diesel.
What about the green pump models? well the mild hybrid petrol alternative is the E 200, another 2.0-litre four cylinder variant, which has 201bhp and, like the E 220d diesel, is boosted by a 23bhp electric motor. That motor, by the way, is now built into the improved 9G-TRONIC 9-speed auto transmission that all E-Class models have to have. The same 2.0-litre engine also features in the E 300e Plug-in petrol model, which offers 312bhp and now gets a larger 25.4kWh battery capable of taking the car up to 69 miles without troubling combustion power. Also a PHEV is the top Mercedes-AMG E 53 HYBRID 4MATIC+ model, which can offer up to 603hp, has up to 59 miles of EV range and can get to 62mph in just 3.8s.
Whatever mainstream E-Class you decide upon, your dealer will want you to consider the pricey optional 'Technology Pack', which adds AIRMATIC air suspension and a rear axle steering system that can add 4.5-degrees of turning angle, reducing the turning circle to just 10.8m.

Design and build
Design chief Gordon Wagener describes this E-Class as 'the business icon of Mercedes-Benz', something you don't mess with, hence an evolutionary take on the 'Sensual Purity' styling theme already established in current versions of the C-Class and S-Class. With 4,949mm of length, 1,880mm of width and 1,468mm of height in saloon form, this MK6 E-Class is slightly larger than before and it's 0.23Cd drag coefficient is slightly sleeker. But you're more likely to notice the smarter gloss black-framed front grille, which can now be back-lit and is flanked by slim LED headlights. The tail lamps are narrower too and get a Three-Pointed Star illuminating signature. As before, there's an estate body style option, but this time round, there will be no Coupe or Cabriolet versions, these body shapes relocated to a newly-created CLE model line-up.
Accessing the cabin can be done via a 'Digital Vehicle Key' stored on your phone. And once inside, the promised 'digital experience' continues, though as with the EQE, the dash seems primarily designed around a premium screen format most models won't have. The 'Superscreen' dash, like the bigger 'Hyperscreen' layout of top EQ saloons, sees driver, passenger and central displays bonded together into one expansive (and expensive) layout. Replaced by acres of empty trim space if, as is more likely, your E-Class has merely a big central portrait monitor and a digital instrument display. Either way, you're treated to a new generation version of the brand's MBUX infotainment system, which can take on third-party apps, access social media services like TikTok and even allow you to run Zoom meetings via an in-built camera. There's more built-in Artificial Intelligence to learn your habits and routines (suggesting new routes or automatically switching heated things on when it's cold). And there's an active ambient lighting bar on the top of the dash that works with the various camera safety systems.
A longer wheelbase means slightly more rear seat space, but the more conventional Modular Rear Architecture platform in use here doesn't of course free up anything like as much leg room for folk at the back as the full-EV platform in the EQE allows for. Boot capacity is 540-litres for conventionally-engined E-Class saloons - and 370-litres for PHEV-powered ones.

Market and model
Expect pricing in the £55,000 to £70,000 bracket for mainstream versions of this E-Class, with a premium of £2,640 if you'd prefer the estate body style. There's a choice of six trim levels - 'Urban Edition', 'AMG Line', 'AMG Line Premium', 'AMG Line Premium Plus', 'Exclusive Premium' and 'Exclusive Premium Plus'. The AMG 53 models start from around £91,000.
There are lots of key options to consider: we'll brief you on just a few of them here. The 'THERMOTRONIC automatic climate control' Digital Vent Control system automatically adjusts the front air vents to a desired ventilation scenario. This can be done for each seat via the car's user profile, but the nozzles can also be aligned by hand as usual. Mercedes has also improved its 'ENERGIZING COMFORT' system with a clever Anti-Travel Sickness programme.
You might also like to add the clever Active Ambient Lighting with Sound Visualisation system, which allows occupants to 'see' music tracks and the sounds of films or apps. Visualisation takes place on dashboard's top Active Ambient Lighting light band. For example, fast sequences of beats can cause rapid light changes, while flowing rhythms can create softly merging lighting moods.
As you'd expect, there's also loads of advanced camera safety and drive assist kit. 'ATTENTION ASSIST', in conjunction with the optional camera in the 3D driver display, can detect signs of microsleep. If the driver's eyes are not focused on the road for several seconds, 'ATTENTION ASSIST' can detect a distraction and warn the driver acoustically and visually. If the driver still fails to turn their attention to the traffic situation, there is an escalation with a second warning and a continuous warning tone. If the driver still fails to respond to the warning, the system will initiate an emergency stop.

Cost of ownership
No matter how advanced this sixth generation E-Class might be, if it doesn't return the right efficiency figures, business folk won't consider it. But of course, Mercedes has covered that off thoroughly here. The volume E 220 d mild hybrid diesel variant that many will want manages 58.9mpg on the combined cycle. Of course, if you really want efficiency in your E-Class, then you'll need to stretch to the E 300e PHEV, which has a segment-leadingly long EV range of up to 69 miles thanks to a now-larger 24.1kWh battery. The E 53 is also now a PHEV and can go up to 59 miles between charges, hence a CO2 return of 21-23g/km.
And otherwise? Well this model series is designed for the long haul. There's plenty of proof of that: Greek taxi driver Gregorios Sachinidis clocked up 2.9 million miles in his 1976 240D and though build quality took a bit of a dip with the W120 series range we had between 1995 and 2003, it's now better than ever with this current 'W214'-series version. This car will easily out-last you, one reason why all-important residual values have traditionally been strong with diesel and lower-order petrol engines. Unless you do something silly like specify an overly bright colour scheme, you can expect to get over 60% of your initial purchase price back after three years.
Another thing we'll need to tell you is that the comprehensive three year unlimited mileage warranty is built upon by Mercedes' Mobilo scheme which delivers breakdown cover for up to thirty years, as long as you continue to have your car serviced at a Mercedes main dealer. And it's worth knowing that your maintenance outlay can be kept a little in check by going for the optional Service Care package that takes care of routine maintenance, spreading the cost of regular servicing, guaranteeing the price of parts and labour for up to four services and covering the cost of all recommended service items such as brake fluid, spark plugs, air filters, fuel filters and screen wash.

Summary
The E-Class remains a cutting-edge statement of Mercedes style and technology - and this 'W214'-series version puts in an impressive performance. Beforehand, it felt like quite an expensive car. Now it feels like one that's pricey but which offers a compelling value proposition. The changes made here future-proof this E-Class a little further against the constant assault from its key rivals. Perhaps the most interesting thing about this sixth generation model though, is the fact that its appeal has broadened so far. It was once hard to see anybody under the age of fifty contemplating an E-Class. A more dynamic image and a focus on sharper design and driving dynamics has seen that demographic become younger. What's more, all this has been achieved without diluting this design's Stuttgart DNA - and without alienating its legacy market. That is the mark of a very special car.
In summary, this is, in short, very much a 21st century full-sized Executive sector conveyance. True, it's slightly more expensive than the competition. Also, there are rivals you could choose that'd be more dynamically rewarding to drive, though as Mercedes well knows, that kind of thing doesn't tend to be prioritised by many likely customers. Certainly if you can see beyond these two issues, then what's on offer here remains arguably the ultimate statement of technology and luxury in this part of the market - and possibly even a package good enough to leave you questioning the need to spend more on a larger S-Class model. 'The best or nothing' was the slogan that Mercedes founder Gottlieb Daimler's lived by. If it's yours too, then we think you'll like this car.
