Mercedes’s newest E‑class, the W214 that reached buyers in 2023, has quietly become the brand’s most pragmatic mainstream saloon at a moment when drivers are deciding between diesel, petrol and electrified options. Its broad powertrain line‑up and refined ride make it a practical choice for company fleets and families alike — and that versatility matters as emissions rules tighten and fuel costs stay volatile.
Quick takeaways
- Range of powertrains: petrol, diesel, mild‑hybrid, plug‑in hybrid and high‑performance AMG variants.
- Transmission and drive: all models use Mercedes’ nine‑speed automatic; rear‑drive and 4Matic all‑wheel drive are available.
- Practicality trade‑offs: PHEVs give useful electric range but shave boot space; the big diesel still excels for long distances and towing.
Electric cars with 400+ mile range: 44 models that cover long trips on a single charge

The E‑class roster runs from the entry‑level E200 to the electrified E300e and diesel‑strong E450d, up to the performance E53 AMG and the range‑topping AMG variants. Across the board Mercedes relies on its 9G‑Tronic automatic gearbox, and you can have either rear‑wheel drive or the 4Matic all‑wheel‑drive system, depending on model.
Powertrains and real‑world performance
The plug‑in hybrids are the headline for many buyers. The E300e combines a 2.0‑litre turbo petrol engine with an electric motor and a 25kWh battery; Mercedes quotes roughly 70 miles of pure electric running and, when both systems are used, several hundred miles of overall range. In daily use the instant torque of the electric motor smooths urban driving and eliminates the typical “range anxiety” that still puts some buyers off pure electric cars.
That said, the PHEV powertrains carry weight. An E‑class PHEV can weigh more than 2.2 tonnes, but despite the extra mass the electro‑hybrid system feels composed: transitions between electric and petrol propulsion are mostly unobtrusive and the package is well suited to mixed commuting and longer trips where charging isn’t guaranteed.
The standout internal combustion option is the E450d. Its 3.0‑litre straight‑six diesel, twin‑charged and helped by mild‑hybrid technology, delivers strong low‑end torque — more than 550 lb ft in real terms — making overtakes and long motorway journeys effortless. The engine feels immediate without the abruptness of some modern electrified drivetrains; it’s the sort of motor that will appeal to anyone who still values long‑distance range and towing ability.
| Model | Powertrain | Approx. power (bhp) | Electric range (miles) | Drive |
|---|---|---|---|---|
| E200 | Mild‑hybrid petrol | ~230 | — | RWD |
| E300e | PHEV (2.0T + electric) | ~300 combined | ~70 | RWD/4Matic |
| E300de | PHEV diesel | — | ~67 | 4Matic |
| E450d | Straight‑six diesel, mild‑hybrid | ~362 | — | 4Matic |
| E53 AMG | Electrically assisted straight‑six | ~600 (AMG claimed) | ~60 | 4Matic+ |
Ride, handling and refinement
Mercedes aims the E‑class at buyers who prize comfort above razor‑sharp handling. With steel springs and adaptive dampers on standard models, and optional air suspension and rear‑axle steering on higher trims, the car soaks up motorway miles with a composure that approaches S‑class levels when fitted with the air setup.
Body control is assured rather than sporty: there’s limited roll in the E450d when you push, but the steering is tuned light and progressive rather than direct. That’s good for relaxed cruising but less appealing to drivers seeking the tactile feedback of a performance saloon.
Brake feel in the PHEV models is an area where Mercedes hasn’t quite nailed the handover between regenerative and friction braking. It can feel a touch inconsistent at low speeds — something buyers used to one‑pedal regenerative driving in full EVs may notice.
Economy, range and running costs
Real‑world tests in cold weather returned around 60 miles of electric driving from the PHEV battery in mixed traffic and motorway conditions, and prolonged diesel runs delivered between 45–60mpg depending on route and speed. That makes the diesel exceptionally frugal for long distance use, while the PHEVs suit commuters who can charge regularly.
- PHEVs: best for mixed urban and occasional long trips if you can plug in daily.
- Diesel: unrivalled for long, uninterrupted motorway runs and towing.
- Mild‑hybrids and petrols: offer a compromise for buyers who rarely charge and want lower complexity.
Interior, technology and practicality
The W214’s cabin bridges the gap between Mercedes’ executive and flagship models: leather, refined trim and an overall fit‑and‑finish that removes the rattles of older Mercs. There are still a few harder plastics in places, but the arrangement feels premium and coherent rather than showy.
Touchscreens and haptic controls run the multimedia and driver‑assist systems. The interface is generally logical, though the wheel‑mounted haptics and highly sensitive voice‑control can be a little fussy in everyday use. Audiophiles should be cautious: the optional 4D sound set‑up includes seat speakers and immersive effects that some passengers may find overbearing.
Rear occupants get near‑S‑class refinement if the car has air suspension; legroom and headroom are generous for an executive saloon and the estate (wagon) versions add useful load capacity. Note that the PHEV battery reduces boot volume to varying degrees, so buyers should weigh luggage needs against the benefits of electric range.
Price and rivals
Mercedes positions the E‑class as a premium alternative to the BMW 5‑series and Audi A6. The Merc typically trades on engineering breadth rather than outright sporting edge: its powertrain choice is the widest of the three, with more PHEV and diesel permutations than most rivals.
Pricing starts higher than some competitors — the E200 opens north of £57,000, while the range‑topping diesels and PHEVs climb considerably from there. For buyers prioritising long‑distance economy and towing ability the E450d is an emphatic choice, but it comes at a premium. For mixed urban commuter work the E300e and E300de present a flexible alternative.
The practical conclusion is simple: if your driving is mainly urban and you can charge regularly, a plug‑in E‑class will be efficient and quiet. If your life involves long runs, towing or frequent motorway travel, the diesel E450d remains a strong, economical proposition — and one of the last large saloons that still makes a conventional diesel feel relevant.
