Renault Arkana vs Mercedes-Benz C350 E

What's the difference?

The Arkana is a stylish alternative in a sea of same-same compact SUVs. It's relatively well equipped and has some hidden gems in its ownership and running costs that elevate it above some of the competition.

It’s not a bad thing to steer, either, but the lurchy dual-clutch could be a deal breaker for some.

The sweet spot is the Techno, which misses out on the Esprit Alpine’s special touches but represents the most bang for your buck.

Plug-in hybrids will probably not appeal to all buyers, but in the premium space they make sense.

Smooth electric driving paired with the potential for weekend trips outside the 100km-or-so range make the C350e a decent thing, let alone its price parity with the C300.

It still doesn’t top the charts for value or practicality, but even aside from the PHEV tech, the C350e remains a fun-to-drive sedan that holds its own in the executive space.

This update isn’t a massive overhaul of the Arkana, rather its “refreshing and enhancing” what was already there according to Renault Australia.

And this remains true with the car’s styling. Not much has changed on the outside except for a few minor garnishes and flourishes, especially on the Esprit Alpine variant.

The coupe styling isn’t for everyone. It’s more popular in Europe than Australia but if you want to stand out from the crowd it’s a good place to start.

The Arkana has curves in all the right places and its little grille made up of little Renault badge diamonds is a welcome addition in a world of wide mouth front ends. The C-shaped LED headlights and a large Renault badge add a bit of pop to its look.

The pinched rear end has LED lighting that runs from the tail-lights to the centre badge and Arkana is spelled out in big, bold letters.

The Esprit Alpine stands out with gunmetal highlights on the front bumper and the front and rear skid plates in the same colour. It also adds a Esprit Alpine badge below the side mirror and front door sill plates.

The Esprit Alpine has 'Tricolour' stitching in red, white and blue on the door trim and steering wheel, which is complemented by blue contrast stitching on the gear shifter, seats and centre console.

Cabin quality is variable. There are some nice feeling materials used on the dash and on the door trims but below eye level there are lots of hard wearing plastics. A big slab of faux wood running along the dashboard doesn’t feel as high-quality as you would like. The quality drops a bit in the back row, which is where carmakers often try to cut costs.

Solid white is the only no cost paint colour, but it is not available on the Esprit Alpine. Metallic white, blue, black, grey and red cost $750.

Buyers can also option a black roof for a two-tone look for $600.

The C350e doesn’t depart massively from the familiar visual formula that is the current ‘206’ generation C-Class and that’s no bad thing.

Call it conservative if you like, but having seen what’s possible when Mercedes takes risks (hello EQ models), the traditional Mercedes design language is put into healthy perspective. 

Handsome proportions and lines without any fuss - there are no unnecessary creases or panels or materials.

The plug-in C350e comes, as mentioned, with the AMG Line pack, adding 18-inch five-spoke AMG wheels, an AMG front apron, grille insert, and of course EQ Hybrid badging.

The pack also includes AMG Line styling inside, where you’d have to be a Mercedes regular to spot the specifics. The AMG-style steering wheel and seats are the biggest giveaways.

The Arkana isn’t a family SUV, but rather is pitched at younger couples and empty nesters. 

Up front there is great forward vision with a higher seating position than hatchbacks and sedans. Electronically adjustable seats and a manually moveable steering wheel means there’s a good seating position for pretty much everyone.

The seats are comfy and the multimedia screen and climate controls are easy to reach. The centre console has a wireless device charger, two USB-A charging ports and a 12-volt socket to keep various devices juiced up. 

Two cupholders take up most of the space with minimal storage space leftover. There are decent sized storage bins in the doors and a little net in the passenger seats footwell to stop small items rolling around. 

Back seat passengers have their own air con vents and USB charging ports, which is a welcome addition.

In the rear pew is where the Arkana’s stylish coupe-like design dents its practicality. The sloping roof shrinks the windows and reduces headroom, which makes it feel a bit gloomy compared to more boxy-shaped SUVs that makes it no-no for smaller kids.

The boot is a decent size, but it’s longer and lower than other SUVs, which is the price you pay for looking good. 

The space inside the C-Class remains straight-forward as ever. The layout and features don’t stray from convention, meaning there’s a sizable central screen, digital driver display, central cupholders, and places to put things like a phone, with wireless charging included.

The electrically adjustable seat and steering column make getting into a comfortable position easy, and the memory settings keep it that way.

While physical buttons are scarce, the key controls are easy to access via the central multimedia touchscreen and there’s a lack of complicated sub-menus. It's a refreshingly straightforward system compared to some from rivals, especially that of former category benchmark BMW.

There are fewer than a dozen main tile buttons on the menu, and they’re clear and easy to work out. The main screen also defaults to the navigation, and the climate controls are always visible on the touchscreen.

The central storage area is laid out so a phone sitting in the charging pad is slightly hidden, meaning it’s not a distraction, plus the cover means the cupholders and storage can be hidden away. Tidy!

The AMG-style steering wheel’s haptic controls can be used as regular buttons, but more than once on the test drive I nudged the volume and turned my music back on, just a minor annoyance.

In the second row, there’s generous space for a mid-size sedan, and the seats are comfortable for an adult to ride along for a lengthy trip.

There’s a centre armrest, hidden cupholders, and a generally light and open feeling thanks to the panoramic sunroof.

The battery for the hybrid system sits under the second row seats, which means there’s no uneven flooring in the 315L boot.

The Mercedes-Benz C350e kicks off from $98,200, that’s before options and on-road costs.

And there are some key options, the main one being the ability to DC fast-charge which costs $1500 and brings the total to $99,700.

Pricing sits par with the C300 non-PHEV because of its similar specification, and Mercedes Australia said it wanted to give buyers the choice of internal combustion engine (ICE) or PHEV without having to consider the costs.

There’s a decent stack of standard kit in the C350e, including power adjustable heated leather seats, a 12.3-inch multimedia touchscreen and same-size digital driver display, head-up display, and wireless Android Auto and Apple CarPlay.

The C350e also scores some more fun stuff as standard, including a Burmester surround sound system, panoramic sunroof, the Driving Assist Plus pack, augmented reality MBUX, and the AMG Line pack which adds some sportier-looking design features.

It also comes with Mercedes’ Comfort Suspension which includes self-levelling suspension, and Digital Lights with adaptive high beam.

The Arkana keeps the 1.3-litre four-cylinder turbocharged petrol engine from before. It makes 115kW and 262Nm and is paired with a seven-speed dual-clutch auto that drives the front wheels. 

That’s plenty of grunt for a car this size, but it’s let down by a glitchy transmission that hesitates a lot at lower speeds and doesn’t do its best work when asked to hustle, either.

The C350e’s plug-in hybrid drivetrain consists of a 2.0-litre turbo-petrol four-cylinder engine and an electric motor that drives the rear wheels via a nine-speed automatic transmission.

The combustion engine’s peak outputs are 150kW and 320Nm, while the 95kW/440Nm electric motor works with it to land on a total system output of 230kW and 550Nm.

While it’s not lightning quick, the C350e has a decent claimed 0-100km/h sprint of 6.1 seconds, and from the driver’s seat it certainly feels brisk enough to get out of its own way.

Efficiency is the name of the game with the Arkana’s little turbo engine. The French brand claims it drinks 5.9L/100km on the combined (urban/extra-urban) cycle but we averaged 7.5L/100km on our circa two-hour country road drive according to the trip computer.

The higher speed twisting and turning country roads we drove on aren’t conducive to low fuel use, though.

It has a 50-litre fuel tank and only requires cheaper 91 RON petrol, which is rare for little turbo engines that usually have premium tastes.

Mercedes officially claims the C350e has a driving range of 104km under NEDC testing, with a 25.4kWh battery supplying the juice.

Official fuel use is just 1.5L/100km, but Mercedes says that becomes 7.6L without any battery charge to help it out.

Under standard 11kW AC charging, it’s about two hours from flat to full, but with the optional 55kW DC fast-charging, it takes about 20 minutes from flat to 80 per cent.

The Arkana is a bit of a mixed bag on the road. Its engine is a nice little unit but the dual-clutch auto deflates the drive experience.

At lower speeds it hesitates and then gives too much oomph all at once, which can result in some wheel spin. It means you need to be mindful at T-intersections and when turning across traffic and feather the pedals. 

This is a symptom of most dual-clutch autos but the Arkana’s is less sophisticated than say ones fitted to Volkswagens, and the Arkana doesn’t have the meaty power and torque bands of performance cars. A conventional torque converter auto would suit it better.

The Arkana does some of its best work at higher speeds, where the dual-clutch is more decisive and it's an admirable highway cruiser. 

It isn’t a bad operator through the bends where it exerts excellent body control to minimise rolling. This is complemented by nice steering that is well weighted and accurate. Pedal feel is excellent with no woody or doughy feel to them.

The suspension is on the firmer side and you’ll feel some harsh bumps, especially over consistent smaller ones that it will crash over.

Its rear torsion beam suspension set-up is less sophisticated than the multilink arrangements found in an increasing number of competitors in the segment.

Road noise is noticeable at higher speeds. There's a fair bit of wind noise, too, but it was an especially windy day on our test drive.

The Arkana isn’t a sports car but is a stylish SUV for punting around town and facilitating weekend getaways, but there are other compact players that answer this brief better.

The C350e has a few drive modes that are mostly self-explanatory, those being Battery Hold, Electric, Hybrid, Sport and Individual.

You’ll likely find yourself using Electric and Hybrid most of the time, so we’ll focus on those. Sport is fine but somewhat defeats the purpose of the plug-in system for day-to-day driving.

In electric mode, the C350e doesn’t feel like it’s lacking any power without the engine helping it along. Acceleration is smooth, brisk enough, and a 130km/h top speed means you won’t need the engine on your commute.

Realistically, its 104km range is probably somewhere closer to 80km, but covers you for a decent daily distance.

Let the car use the engine to help out via Hybrid mode and, if you’ve got music playing, you might not notice the engine starting and cutting. The system is smooth and it means a much longer life out of the battery before needing to charge. That, and there’s the benefit of more brisk acceleration thanks to the hefty 230kW/550Nm total outputs.

Everything else about the C350e is classic C-Class - the ride is controlled and the suspension does a decent job of soaking up bumps and rough roads, the comfort and self-levelling suspension makes cornering smooth and inspires confidence.

The most noticeable shortcoming for the car is its transmission hesitation if you put your foot down quickly, though the ability to use the paddles to choose your own gears in Sport mode avoids this.

In Electric or Hybrid, the paddles decide how much braking regen to apply, a useful feature that lets you recuperate some power for the battery if your drive includes a lot of downhill slopes or if you’re avoiding relying on the brake pedal.

The C530e’s extra weight doesn’t dull its driving characteristics as you might expect from a car laden with PHEV tech, so it’s a welcome surprise that you could pick up a plush plug-in for the same price as a combustion C300.

The C-Class has a five-star ANCAP rating, but it was tested in 2022 before the plug-in variant arrived.

Still, 10 airbags and an advanced list of safety features provides peace of mind.

The C-Class benefits from the brand’s Pre-Safe collision protection system to minimise occupant injuries from an impact, even to your hearing.

It also has emergency collision avoidance via steering input, driver monitoring, speed limit assist with adaptive cruise control, and parking sensors with surround-view cameras.

There is one part of Renault’s ownership credentials that others can’t match.

Its service intervals are every 12 months and a whopping 30,000km, which is double the industry norm of 15,000km. 

If you need to do big kays such as a sales rep or rideshare driver might this will be extremely important.

Five years or 150,000km of capped price servicing visits costs $2385, which is one the expensive side compared to Honda, Hyundai and Toyota but is in the ballpark of similar-sized Kias and Volkswagens.

Renault covers the Arkana with a five year/unlimited km warranty - par for the course in the mainstream market - and five years of roadside assistance.

Mercedes has a five-year, unlimited kilometre warranty which is decent for a premium brand.

Servicing is pricey, though. 

A three-year pack covering a service every 12 months (or 25,000km, whichever comes first) costs $3355, that being just three services.

Four years costs $4630, or five includes a more expensive service and brings the total to $6890. That’s an average of $1378 per service.

Finding somewhere to spend that money shouldn’t be hard as there are 100 dealers listed in Australia.
