Renault ZOE vs Mercedes-Benz A-Class

What's the difference?

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 new AMG C 43 may lack the drama and excitement we’ve come to expect from the German performance brand, but that doesn’t mean it’s a bad car. Yes, it could be more extroverted and the ride could be improved, but this is still a sharp-looking sports sedan with loads of punch.

This is a car that speaks to its times, with ever-stricter emissions regulations making it harder and harder for car companies to produce loud, wild and charismatic cars. So Mercedes-AMG has worked within those boundaries and come up with a car that retains at least some of those core elements that has made the brand so desirable over the years.

Note: CarsGuide attended this event as a guest of the manufacturer, with accommodation and meals provided.

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.

Mercedes has created something of a problem for itself with its decision to introduce AMG styling packages for the majority of its range, including the C-Class.

It means the C 43 has to walk a fine line between looking like a unique AMG model, rather than just a C300 with a bodykit and not out-doing the C63.

To that end it has AMG’s now familiar grille with vertical bars, the unique and complex-looking 20-inch alloy rims and a small lip spoiler on the boot. But otherwise it is surprisingly understated for an AMG, lacking the more obvious and muscular stance of previous AMG offerings.

Inside, there’s a similar theme, with the typical Mercedes-Benz luxury appointments but with a sportier, AMG twist. The steering wheel is chunky and comes with AMG branding, metallic shift paddles and a pair of rotary dials/buttons that allow you to alter the various drive modes and settings.

The one on the right allows you to switch between the pre-set Comfort, Sport, Sport+ and Individual modes, while the one on the left can scroll between the various individual aspects to tailor the settings to the conditions.

In typical modern fashion the design is tech-laden, with a digital display for the instrument panel (that can be switched between various graphics) and a large, tablet-style central multimedia touchscreen that controls the majority of the car’s non-driving functions.

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).

The new C-Class has grown slightly in size compared to the model it replaces, most notably with a 26mm increase in the wheelbase which you can feel in the cabin.

The front seat space is good, with excellent adjustability for the power-adjustable seats and steering column. I had no trouble finding my ideal seating position which makes for a more enjoyable and uncompromised driving experience.

Rear space is a bit tighter (which is typical for this segment/size of vehicle), but thankfully the standard seats do have very deep sculpting in the backs which allow for more knee space and foot room.

However, at approximately 180cm (six-foot), I wouldn’t like to sit behind my seating position for long periods as my knees were touching the seat back, and headroom is compromised with the panoramic glass roof.

In terms of small item storage there’s a lidded console box in between the front seats as well as a pair of cupholders and a small tray where you can place your mobile phone.

It’s worth noting, though, that early examples of the C 43 in Australia do not have a wireless smartphone charging pad, with that reportedly being introduced from February production.

While that’s good news, it’s not really competitive in this day and age to offer a car costing six-figures without such technology.

There’s also only a single USB-C power outlet in the front, which is another disappointment, but there is a pair in the back.

Mercedes does win some points back for a respectable 455-litre boot, which has a nice wide load opening that will make packing luggage easier.

We’ll get to the major change under the bonnet shortly, but another significant alteration for this latest C 43 is the price.

It now starts at $134,900 (plus on-road costs), which pushes it well above its market rivals, the BMW M340i xDrive and Audi S4, which start at $104,900 and $106,200, respectively.

However, Mercedes has added more technology under the bonnet and loaded the C 43 up with standard equipment, including its '4Matic' all-wheel drive system, adaptive damping, rear-wheel steering and 20-inch alloy wheels.

In terms of creature comforts, the C 43 is well-appointed, with leather upholstery, a head-up display, augmented reality navigation, a panoramic sliding sunroof, and a Burmester 3D surround sound system.

There are two option packages for the C 43. The 'Digital Light Package' costs $2400 and adds Multibeam LED headlights with 'Ultra Range' highbeam, 'Adaptive Highbeam Assist Plus' as well as active light function and cornering light function.

The 'Performance Ergonomics Package' includes AMG Performance front seats, an AMG Performance steering wheel in Nappa leather and microfibre and the 'AMG Track Pace' system for an additional $5200.

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.

The biggest talking point about this new car is the engine, with AMG downsizing from the old C 43’s six-cylinder to a 2.0-litre four-cylinder turbocharged petrol engine.

But it’s not just any turbocharged four-pot, because it is fitted with technology that Mercedes claims has been inspired directly from its Formula One team.

While the F1 team engine facility is based in England, this engine was designed and developed by the Mercedes-AMG team at its Affalterbach headquarters, but the concept of the electric turbocharger reportedly comes from the engine that powered Lewis Hamilton to multiple world championships.

The electric exhaust gas turbocharger - to give it its official name - uses a small electric motor on the turbocharger shaft to spin up the blades without having to wait for any exhaust gases to pass through it first.

To power the electric turbo the C 43 is equipped with a mild-hybrid 48-volt electrical system.

Mercedes claims this means reduced lag and improved throttle response for a sportier driving experience. 

It also helps make this small engine produce big amounts of performance, with AMG extracting 300kW of power and 500Nm of torque from this 2.0-litre, which is more power than the previous six-cylinder C 43 managed.

The engine is paired to a nine-speed multi-clutch transmission, which isn’t a dual-clutch with a pair of clutches operating on every second gear ratio, but instead uses a “wet start-off clutch” for better take-offs and smoother shifting on the move (at least in theory).

Power is sent to the road via all four wheels thanks to Mercedes’ 4Matic all-wheel drive system.

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.

Despite the smaller engine you can hardly call the C 43 miserly, with a claimed combined urban/highway cycle rating of 9.1-litres per 100km. That’s only a 0.2L/100km improvement over the old six-cylinder.

On test, which included a return trip from Sydney to Bathurst via motorways and some dynamic back road driving, we saw a return of 11.8L/100km on the car's onboard computer.

While hardly hybrid-worrying, it’s impressive to think that driven modestly, such a potent engine can return a single-digit fuel figure.

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.

Let’s start with the good news. The new Mercedes-AMG C 43 is a quick car. The engine may be small in size but the electric turbocharger does its thing and provides plenty of punch.

You can get a performance boost, too, thanks to the belt-driven starter generator, which acts as a mild hybrid and gives you a surge of 10kW for a brief period if you need a sudden burst of extra speed.

The chassis is well-sorted, too, at least from a dynamic point-of-view. The rear-wheel steering can provide up to 2.5 degrees of turning, which improves handling at speed and manoeuvrability when parking.

However, there are some less-impressive elements to the C 43, too. The obvious one is the drama, or rather the lack thereof.

As I said at the beginning, the C 43 has never been as wild or raucous as the V8-powered C 63, but when you buy an AMG there’s a rightful expectation that it will provide some thrills.

The C 43 simply doesn’t have that character about it. Yes, it’s fast, but it produces that speed with efficiency rather than excitement.

And it’s not an engine size problem, because even the 2.0-litre four-cylinder A 35 and CLA 35 offer more ‘wow factor’ than the C 43.

Yes, the engine makes noise under acceleration (and it can be altered between discreet and sporty) but even at its best it sounds muted and lacks the evocative tone of a V8 or six-cylinder engine. 

Another disappointment is the transmission calibration, with the gearbox awkwardly shifting out of first gear on multiple occasions during our test drive.

In the taller gears it felt smooth enough cruising along, but given its low speed shifts we’d like to spend more time in the urban environment before passing final judgement. 

The other notable element of the driving experience we struggled with was the ride quality. While fine on the smoother motorways, our test drive included time on some patchy country back roads and the C 43, even in the ‘Comfort’ suspension setting, was simply too firm.

Riding on low profile tyres, the adaptive dampers struggled to isolate the cabin from the imperfections in the road, leading to a fussy ride at times.

Overall the C 43 is a good car, but it feels like there are still some areas where Mercedes could improve it to make it really live up to the AMG badge.

The C43 gets a comprehensive list of safety equipment that leaves little out. Obviously there are the usual passive safety items, like 10 airbags, including dual-front combined pelvic/thorax airbags and a front centre bag that drops between the front seat passengers to minimise the chances of a head clash.

Also included as standard is autonomous emergency braking front and rear (covering speeds between 7.0-200km/h), adaptive cruise control with active stop/go, a 360-degree parking camera, 'Active Parking Assist', 'Active Lane Keeping Assist', 'Blind Spot Assist' and, of course, anti-lock brakes with 'Brake Assist' and 'Adaptive Brakes' with Hold function and electronic stability control.

Also included are dusk-sensing LED lights, rain-sensing wipers and run-flat tyres with tyre pressure warning.

The C43 also comes equipped with Mercedes’ 'Driving Assistance Package Plus', which adds even more safety gear. This includes 'Active Blind Spot Assist', 'Active Brake Assist with Cross-Traffic Function', 'Active Emergency Stop Assist', 'Active Lane Change Assist', 'Active Lane Keeping Assist', 'Active Steering Assist', and 'Active Stop-and-Go Assist'.

While the C43 hasn’t been specifically crash-tested, the latest C-Class was rated by ANCAP with a five-star score for all models except the upcoming C 63 S E Performance.

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.

The C 43 is covered by Mercedes’ five-year, unlimited kilometre warranty, which has become the new standard for the luxury car market.

Service intervals for the car are at 12 months/25,000km, which is on par with industry standard.

Mercedes-Benz Australia will offer a service plan for the C 43, prices were yet to be confirmed at the time of publication but the company has indicated it will be similar to the C300. 

That means $550 for year one, $900 for year two, the third service costs $1000 and the fourth year service costs $2450 - for a total of $4900 for the first four years of ownership.
