Mercedes-Benz E-Class vs Renault ZOE

What's the difference?

It's nice to see the E-Class still embody the ancestral heritage of Mercedes-Benz, a brand which has had much change forced upon it in the last decade.

This hybrid one in particular does a remarkable job of blending the future and the past in one deeply capable and customisable package, but not one without its flaws.

While the E 300 e manages to unite these elements nicely, it's ultimately held back by its classic rear-drive underpinnings which have consequences for packaging and electric range.

The Renault Zoe is a fun to drive, ultra-efficient, practical little hatch. But the dollar-shaped elephant in the room is its price. Without the government ZEV subsidies offered in other markets, it's wickedly expensive, and with fresh competition in the shape of a new 'normalised' Nissan Leaf coming soon it'll have to work hard to wean more than a handful of small-car buyers off their fossil-fuel addiction.

The E-Class recently received a significant facelift to bring it in line with the brand's latest design ethos, and it serves to refine an already elegant sedan.

The E-Class isn't just the brand's definition by reputation, but by its look, too. While some may be disappointed by how similar it now looks to the C-Class below, or the S-Class above, giving the core Mercedes sedan range near identical silhouettes, it cuts a unique path from its traditional rivals.

BMW's 5 Series leans into a sharper and more aggressive design language, while Audi's A6 does much the same with a post-modernist edge.

I'd argue the stoic Germanic stare of the E-Class’ softer face places the Mercedes exactly where it needs to be, but it doesn't stray from its sporty rear-drive underpinnings entirely.

The car's new blacked-out highlights accentuate its width, and the 10-spoke alloys on our test car fill the wheelarches and draw your eye to the car's low stance and big brakes.

A classic Benz beltline runs from the front lights to the rear, uniting a tidy and clearly well-built package.

Inside and the more luxury-focused touch of the E-Class compared to rivals is evident. Lavish wood trims work their way through the doors and across the grandiose dash, and while the flashy screen fittings from the wider Benz range are present here, the interior is toned down several notches from the glitz of the brand's smaller vehicles.

This offers it a much more stately ambiance, matched by the synthetic leather ‘Artico’ seats which are more like lounge chairs you sink into.

The overall design links the E-Class with its siblings nicely, and there are a lot of the brand's re-imagined classic touches present, like the circular climate vents, wooden panel inserts, and silver-tinged toggles which run down the centre.

It's not all retro, though, with the E-Class wowing observers with its giant single gloss panel hosting the multimedia suite and digital dash elements.

Obviously, you can go further here, with a long list of optional interior colour and trim combinations to customise the E-Class to your heart's content, although I was happy with the classic black on brown woodgrain of our test car.

Renault claims no less than 60 patents came out of the Zoe's development, but while BMW's i3 is as hip as Kendrick Lamar on his third encore, and even Toyota's long-serving Prius hybrid still looks ready to roll onto the set of the next Avengers movie, this little hatch isn't shouty at all.

It seamlessly merges into the automotive landscape. A cute, small car with a few flashy blue bits in its head and tail-lights giving the only clue to its distinctly unusual internals.

Underpinned by the same platform as the Clio (with an identical wheelbase) the Zoe is slightly longer (+21mm), fractionally thinner (-2mm) and quite a bit taller (+114mm) than its conventionally powered sibling.

Lead exterior designer  Jean Sémériva has literally left his mark on the car, with a full-size thumb print applied in low-relief to the rear door handles. Nice touch.

And monsieur Sémériva has shown admirable restraint in a cool design combining soft curves around the nose, front guards and rear end, with sharp character lines top and tailing the car's flanks.

Vaguely diamond-shaped tail-lights mix a clear lens cover with those nifty blue highlights and brilliant LEDs for an arresting brake and indicator display.

Open the door and a similar blend of tech and tradition creates a clean and simple interior, with strategically placed bright-metal finishes highlighting key elements.

A broad TFT digital instrument screen sits under a minimalist hood, with the 7.0-inch 'R-Link' multimedia screen dominating a central stack lifted by a shiny black face and an illuminated blue keyline around the heating and ventilation controls.

A printed circuit pictogram on the front headrests and left-hand side of the dash is a creative reminder of the Zoe's means of propulsion. And the front seats feature a decorative curved panel, defined by dark piping on each side of the backrest.

Tech highlights include the TomTom Live nav system's ability to describe a circle showing the car's operational radius on current charge, determining whether you can reach a nominated destination. It also taps you into weather updates, traffic danger zones and Renault Assistance.

Plus, the drive-management system can report on energy usage and assess driving behaviour, so lead foots have nowhere to hide.

The E-Class takes many forms around the world, and one of them is a taxicab which makes a lot of sense because the E-Class is one of the few cars I've had on test of late that I'd actually like to be driven around in rather than always take the helm myself.

The rear seat space is enormous behind my own driving position, and the detailed luxurious trims continue, complete with the dazzling milled silver speaker fittings, woodgrain trim, and in our test car, rear heated seats.

Again, the seats are ones you simply sink into, and the window is nice and wide for great visibility.

Alongside rear heated seats in our car, amenities include large bottle holders in the doors, flip-out ones in the armrest, hard shell pockets on the back of the front seats, as well as dual adjustable air vents with a lock-off.

The front seats also offer generous space, comfortable and supportive designs, and a lavish space for full-sized adults with a high level of adjustability.

As much as I hate the fact that you have to tick pricey option boxes on an already pricey car, the amenities they afford are properly luxurious.

The seat heating, for example, extends to the armrests in the doors and centre console, and the third climate zone is a necessary touch if you're ferrying around rear passengers often.

While a sedan like this is never going to have the ease of seating of an SUV, there are lots of little areas where this Benz shines.

Proper four-door keyless entry is a nice touch. As is the ability to pre-condition the cabin, the way the doors open nice and wide, and the 40/20/40 split fold of the rear seats allow you to use the centre fold as a ski-port in European style.

Up front, you can customise the digital dash how you see fit, and while the touch panel controls on the wheel and centre console can be clumsy at times, at least there are multiple ways to interact with the system, and a physical dial for volume control hasn't been forgotten.

Over time I've even warmed to the centrally-located touchpad controller. It's easier to use than the one in Lexus products, and it's nice that I have a way to interact with the piano-gloss screen without needing to reach over to it while I'm concentrating on the road (leaving finger prints all over it in the process).

Even things as simple as the car's instruction manual being entirely digitized into the multimedia suite, complete with search function, is just smart.

The layout of the E-Class creates a significant reduction in boot space in this hybrid version, however.

Because it's a rear-drive sedan, it requires the batteries to be awkwardly packaged under the floor and on top of the axle, so the boot floor is an odd, tiered surface, with space reduced from a decent sedan-sized 540 litres (VDA) in purely petrol variants to a hatchback-sized 370L in this PHEV.

As you might be able to tell from the pictures, this shelf arrangement makes the space hard to use, although it did manage to fit our largest (124L) CarsGuide travel case on an angle.

Like most compact hatches the Zoe offers plenty of space up front and gets a bit squeezy in the back. Although the first surprise is that there's no height adjustment for either front seat.

Happily that wasn't a big issue. At 183cm I was still able to find a good driving position, with storage running to two cupholders (one small, one laughably tiny), plus a pen slot and two oddments trays in the centre console. The second of those trays houses a 12-volt outlet, SD card slot, 'aux-in' jack and USB port.

There are small bottleholders and storage pockets in each front door, a medium-size (7.0-litre) glove box with an open tray above it, and a small tray on the lower part of the dash on the driver's side.

Rear head and legroom is passable for a car of this size, but storage is limited to modest door bins and a single cupholder at the back of the centre console.

However, it's cargo space where the Zoe really raises eyebrows, with 338 litres available (to the parcel shelf) with the single piece rear seatback (as in, it doesn't split-fold) upright.

That's enough to easily swallow our three-piece hard suitcase set (35, 68 and 105 litres), or the CarsGuide pram. In fact, we were able to fit the largest suitcase and the pram at the same time, which is mighty impressive for a city-sized hatch. Push the rear seat flat and space grows to 1225 litres (to the roof), which is heaps.

Carpeting for the boot has been sourced from the cheap 'n' cheerful bin, but there are D-shaped anchor shackles, decent lighting and handy bag hooks back there.

The boot's unlikely volume is partly due to the absence of a spare of any description, a repair/inflator kit being your only option. And in case you were wondering, towing is "prohibited" (Renault's word, not mine).

Built at Renault's Flins plant, 40km west of Paris, on the same line as the Clio, the Zoe's offered in two grades; Life ($47,490, before on-road costs), and Intens ($49,490 BOC) as tested here.

That's big bucks for a little car. At just under $50,000 you're looking at internal-combustion competitors like the Audi A3, BMW 1 Series, and Merc A-Class. And while the Zoe's a long way from spartan, it's an equal distance away from luxurious.

That said, the standard features list includes, climate control (with remote 'pre conditioning' activation), 16-inch 'Black Shadow' alloy rims, cruise control, 3D Arkamys audio (with DAB radio, voice recognition, two 'boomer' speakers, two rear bi-cone speakers, and two tweeters), 'Renault Smartkey' keyless entry and start, auto headlights, and rain-sensing wipers.

Plus, you also get rear parking sensors, a reversing camera, the 7.0-inch 'R-Link' multimedia system (with 'Text to Speech' function), one-touch driver's window (the base Life grade misses this), a leather-trimmed steering wheel and gear knob plus black and grey cloth trim (with snazzy contrast stitching).

The DRLs may be LED but the headlights are halogen (a sure sign of this car's age), Apple CarPlay and Android Auto are MIA, and metallic paint, as per 'our' car's 'Zircon Blue' finish is $550 extra. 'Glacier White' is the only no-cost option from six available shades.

The E 300 e has a 2.0-litre turbocharged four-cylinder petrol engine producing 155kW/350Nm mated to a nine-speed torque converter automatic transmission, driving the rear wheels.

The transmission contains an electric motor which is capable of producing 90kW/440Nm on its own, allowing full range of motion in the ‘Electric’ driving mode.

It is also capable of hybrid assistance to the petrol motor, making the E 300 e the fastest non-AMG-badged E-Class model to 100km/h, with a claimed sprint time of just 5.7 seconds.

It also has a 13.5kWh lithium-ion battery pack, which is good for a claimed electric-only driving range of 51km (on the more lenient NEDC testing cycle).

It's a complex mix of gear, and the electric range I experienced was certainly less than 40km. In other words, it's used up very quickly.

The Benz offers some interesting driving modes to help with this, which we'll explore later in this review.

The Zoe is powered by Renault's R90 synchronous electric motor, producing 68kW from 3000-5000rpm and 225Nm from step-off. Drive goes to the front wheels through a single reduction gear auto transmission.

Claimed acceleration for the city-specific 0-50km/h run is a handy 4.0sec, with the more grown-up 0-100km/h sprint taking a leisurely 13.2sec. Flat biscuit is 135km/h.

All of this hybrid gear leads to impressive consumption figures. Officially the E 300 e will consume just 2.2L/100km on the combined driving cycle, with around 13.0kWh/100km of energy consumption worked in as part of that calculation.

However, the hybrid Benz requires 98 RON premium fuel, has a smaller tank (60L) than its all-combustion counterparts, and its claimed 51km of NEDC range is more in the late thirties or early forties in the real-world in my experience.

That said, our car consumed a blend of 5.6L/100km and 8.3kWh/100km in my time with it, which is a nice balance of fuel and energy consumption.

I drove it with a lot of electric mode in the mix, but also had a day solely on the engine, and some experimenting with 'Sport' mode and 'Battery Saver' which is designed to maintain the battery level whilst using hybrid mode where it can.

The E300 e accepts a European-standard Type 2 ‘Mennekes’ charging cable in AC form only. It can charge at a theoretical max speed of 7.4kW, although the max I extracted from my local solar-charged AC outlet was 7.2kW.

It took around an hour and a half to get my E 300 e to about two-thirds charge. It would have charged to 100 per cent in around two hours using this method.

Expect somewhere between four and five hours for it to charge to 80 per cent from a 2.4kW wall socket with the included charger.

The system as a whole works well, but I wish it had more purely electric range. A battery closer to 20kWh would offer 60 or 70km of real-world range for a car of this weight, but would eat significantly more boot capacity.

None. Next question...

You can have the argument about fuel consumed and source emissions produced in generating the energy required to charge the Zoe's battery, but the fact is this car doesn't consume any fossil fuel and produces zero tailpipe emissions. Helped by the fact it doesn't have a tailpipe.

When launched in 2016, the Zoe's upgraded 41kWh 'Z.E. 40' high-energy lithium-ion battery ranked as the highest energy density automotive unit available.

Developed in collaboration with LG Chem in South Korea, it houses 12 modules (of 16 cells each) for a total of 912 individual cells and weighs in at 305kg.

Renault lists a driving range of 403km for the New European Driving Cycle (NEDC), with a real-world number of 300km a more realistic estimate. And that's almost exactly the range we achieved over a mix of city, suburban and freeway running in seven days with the car. Using overnight electricity rates, a full charge should average less than $8.00.

The Zoe's on-board 'Chameleon' charger allows it to be charged using different power levels (single or three-phase) through the same socket, from 3kW up to 22kW. A Type 2 charging cable (6.5m) for wall box and public charging points (in a natty canvas Z.E. bag) is included with the car.

According to Renault, a wall-box charger (not included with the car) is typically $1600 to $2000 for a residential installation and a mid-range 11kW unit will allow you to charge up in around four hours. High-powered 'Fast' and even juicier 'Rapid' charging points would reduce that time appreciably.

The dash indicator displays charge level and remaining range calculated over the last 200km of driving. A reset function can drop that to an average of the last 30km.

We'll touch on it further in the Driving section but regenerative braking, low-rolling resistance tyres, and 'Eco' mode (reducing air-con load and motor output) are big contributors to maximum range.

And while cabin cooling comes courtesy of a conventional a/c unit, heating is far more exotic. The Zoe's 'Heat Pump' system traps calories in the ambient air outside the car, with a pump compressing and heating them, then directing the heated air into the car, with no impact on range. Super clever.

For all the electrification and evolution in Mercedes-Benz’ greater range, it's almost like coming home to sit in the E-Class.

Not only does the E 300 e stay true to the brand's luxury sedan roots with the comfort and refinement on offer, but it's perhaps the one variant in the E-Class range that makes a significant stride toward the future of the nameplate.

I'm sure we'll see a fully electric version of the E-Class in the near future (the brand is shifting to electric-only with an aggressive timeline), but for now, at this price, hybrid is the way forward for luxury sedan refinement.

The way this car blends its electric and combustion modes is notably smooth, and the engine is so distant it's genuinely hard to tell when it turns on, unlike this car's smaller A 250 e PHEV hatch sibling which takes a major drop in refinement when the rattly 1.3-litre four-cylinder engine needs to be relied upon.

This is likely due to the higher-end nature of the 2.0-litre engine and nine speed longitudinally mounted transmission in a much larger and heavier car. One thing I've never liked about the Mercedes PHEVs (and is a common problem among many PHEVs) is the ‘hybrid’ mode could be a bit smoother and more transparent on how it divides its time between electric and with the engine on. At times it runs the engine at the lights for no reason, and it seems unusually keen to turn it on when it could be using electric power. Perhaps we are spoiled by the simplicity and twenty years of refinement of Toyota's Hybrid Synergy drive, but it has the affect of making you wish every hybrid was as good.

The default ‘Comfort’ mode, while the most forgiving in terms of this car's ride, is weighted toward entirely draining the battery before it uses combustion power. The extra drive modes and customisation this PHEV offers are very useful though. Battery Saver mode lets you rely predominantly on combustion power. It's better to use on the freeway where combustion power is at its most efficient, allowing you to switch back to Comfort or Electric when you're stuck in traffic.

Sport hunkers the E-Class down for a sportier and firmer experience, and it also tweaks the accelerator response and auto transmission for a far more aggressive driving tune. As this mode won't use the electric motor at all, even at low speeds, it can be handy to use it to charge the battery via regenerative braking for times when you might not have access to a charger.

In fully electric mode, the regen braking can be tweaked to the max using the paddle shifters to increase your electric efficiency and range.

Like the smaller A 250 e, it's a highly customisable experience, letting you experience as much or as little electrification as you want in the moment, although in this case it's let down a little by the limited battery capacity.

Still, the E 300 e is an E-Class, quieter and sleeker than before. The ride is as stately as the interior suggests, and even on those 19-inch wheels little noise or discomfort makes its way into the plush cabin. The transmission is as close to an old ‘slush-o-matic’ you can get, and I mean that in a good way. Unless you're in one of the Sport modes, it will never interfere with the experience from behind the wheel.

Once you do awaken it in Sport or Sport + though, it shifts, even via paddles, with a surprising urgency, and it's in those modes where the air suspension transforms the cosy barge-like ride from Comfort or Electric into something far more rigid and responsive.

The dynamic breadth of ability in this car is a reminder of what premium money like this can buy. On the one hand you have the luxury of an economical comfort saloon, and on the other you have at least an inkling of semi-electrified performance at the flick of a switch.

Just remember to plug it in when you get home, or you're lugging around a lot of battery for no good reason.

Some believe cars have a soul, but the Renault Zoe expresses its feelings with a distinctive accent, the car's 'Z.E. Voice' function giving an audible warning to pedestrians up to 30km/h (when wind and tyre noise take over).

The whirring hum sounds like The Beach Boys warming up the theremin for a rendition of 'Good Vibrations'. Spooky and fun in equal measure.

Like all electric cars the Renault Zoe accelerates quickly from rest, thanks to the motor's ability to deliver maximum torque (225kW) from step off.

At 1480kg (battery 305kg) the Zoe is 177kg lighter than an equivalent Clio, so it's snappy in its natural city habitat, but thrust begins to taper off markedly around the 55-60km/h mark.

The single-speed, reduction gear automatic transmission combines with the motor's sewing-machine smoothness to provide close to perfect drive delivery.

Sitting on the same 'B platform' as the Clio (and 20 other Renault–Nissan–Mitsubishi Alliance models) the Zoe features a strut front, beam rear suspension set-up.

Ride comfort is surprisingly good for such a small hatch, and the battery's location under the floor sets up a centre of gravity 35mm lower than the Clio's, so despite a 59 per cent front/41 per cent rear weight distribution, the car feels well planted in corners.

...the dash graphic – a blue AA-style battery surrounded by rising rings of energy – is reminiscent of 'the machine man' animating in Fritz Lang's Metropolis.

The standard 16-inch alloy wheels are shod with Michelin Energy E-V low-rolling-resistance tyres (195/55), which won't win you pole on a qualifying lap, but are commendably quiet.

There are three driving modes, with the dash graphics aligning to each – Eco (green), Neutral (blue), and Dynamic (violet).

But ECO mode should be reserved for hardcore environmental warriors only. Press the console-mounted button and power from the motor is reduced and air-con output is limited.

It may increase range by a claimed 10 per cent, but what price your sanity? This setting sucks out the car's will to live, and thankfully a second press of the button or pinning the throttle pedal to the floor sees full-strength service resumed. Phew.

The regenerative deceleration and braking system distributes braking force between the clamping of the brake pads and the engine on over-run to maximise battery charge.

While the BMW i3's regen system will have you head-butting the steering wheel (not really) when you get off the throttle, the Zoe's system is more subtle, and watching the dash graphic – a blue AA-style battery surrounded by rising rings of energy – is reminiscent of 'the machine man' animating in Fritz Lang's Metropolis.

Speaking of brakes, the fronts are relatively delicate 258mm vented discs and the 9.0-inch rear drums look like miniature versions of the elaborately fluted units found on 1920s Grand Prix racers. They're beautiful and work well.

Some niggles. The wipers skip and stutter in light rain, the lightweight doors feel clangy when you close them, and the R-Link multimedia system is annoyingly flaky when recognising content (or not) via Bluetooth or USB from a mobile device.

The Zoe hasn't been assessed by ANCAP but was awarded a maximum five-star ranking by EuroNCAP in 2013, with annual reviews allowing it to maintain that score through to April this year.

Active crash prevention tech includes ABS, EBD, EBA, ESC, traction control, tyre-pressure-loss sensors, rear parking sensors and a reversing camera.

But forget about more recent systems like AEB, lane-keeping assistance, blind-spot monitoring, cross-traffic alerts or adaptive cruise.

Interestingly, the Zoe continuously monitors the state of each cell in the battery pack and will switch off current immediately if it senses an overheating-style abnormality.

If an impact is unavoidable the airbag count runs to six - driver and passenger front, front side (head and thorax), and full-length side curtain.

There are three top tethers and two ISOFIX positions for child seats/baby capsules across the back row, and all seats feature Renault's 'Fix4Sure' anti-submarining design.

Mercedes covers all its passenger cars with a five year and unlimited kilometre warranty, beating out its primary Audi and BMW rivals which persist with three-year offerings, and generally out-performing the premium segment.

The E-Class needs to be looked at once every 12 months or 25,000km, whichever occurs first, and like many German automakers, service packages can be bundled in at the time of purchase to bring overall costs down.

In the case of the E-Class, this will set you back $2450 for three years, $3200 for four years, or $4800 for five years, at a claimed minimum saving (three years) of $550 compared to paying-as-you go.

It's not as expensive or as unknown as it used to be here, but at close to $1000 per year, even when purchasing via the pre-paid packs, it's still very much at the premium end.

According to Renault, the R90 motor is "maintenance-free", waterproof and requires no lubrication, with servicing costs "20 per cent lower than an equivalent ICE (internal combustion engine) vehicle."

Despite that, servicing is recommended every 12 months/30,000km for an estimated cost of $231 each time.

Warranty is three years/unlimited km with 24-hour roadside assist included for the first year, and three after that if you have your car serviced at an authorised Renault dealer.

The battery is covered by a separate five year/100,000km warranty.
