Mercedes-Benz CLA-Class vs Genesis G70

What's the difference?

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.

The updated Genesis G70 3.3T Sport Luxury is beautiful to look at and drive. It features premium features, trims and great power but the cabin is tight on space. Which makes it a little awkward to use, so this will suit a small family best or families where this may not be the primary mover. That said, I love the after-care program and it suited my small family of three, so it gets an 8.0/10 from us. 

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.

The G70 sedan is absolutely gorgeous to look at and the our test vehicle's 'Kawah Blue' paintwork makes the crisp pleating across the body stand out.

The G70 has a muscular stance, much like its BMW rival, but the rear is softer in its shaping.

The front looks sophisticated with the wide-set LED lights and black air-intake vents. The sporty 19-inch alloy wheels and red calipers behind them hint at what the powerful V6 engine can do.

The interior looks high-end with our test vehicle’s white quilted Nappa leather upholstery and a soft-touch black headliner. The dashboard looks solid and robust but the slick looking 10.25-inch touchscreen multimedia system and digital climate control panel elevate the overall design. 

The only thing I didn’t like about the design was the ambient lighting. It’s limited to two panels on the roof and is a little distracting when you drive at night. I think if it was scattered more throughout the cabin, it would be less intrusive.

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.

The practicality is hurt a little by the space available for passengers. The front row benefits the most when it comes to head- and legroom but if you’re ferrying passengers in the back seat, you’ll have to scoot your seat forward to accommodate them.

Especially if they’re tall because my knees brush the back of the driver’s seat when it’s in my driving position and I’m only 168cm tall!

The individual storage options throughout the car are okay for the class with the front enjoying a small middle console and glove box, two cupholders and two small drink bottle holders in each door.

The rear gets map pockets, two cupholders in a fold down armrest and two very small storage bins in the doors.

The other amenities are great in both rows and a high-level of comfort will be found for adults with the heat and ventilation functions on the front seats and the heat function on the rear outboard seats.

However, the width of the rear seat and the tall transmission tunnel means the middle seat should be strictly reserved for a kid. Think of the G70 as more of a four-seater if you have adults to carry.

The boot has a 330-litre capacity and it’s not too hard to reach to the very back if items roll that way. The back seat has a 60/40 split and there is a temporary spare tyre underneath the floor. 

In terms of technology, you get a USB-A and USB-C port up front, as well as, a 12-volt socket and wireless charging pad to choose from. Rear passengers get two USB-C ports and the boot features another 12-volt outlet.

The 10.25-inch multimedia system looks great and is easy to use with a responsive touchscreen. It also has built-in satellite navigation, wired Apple CarPlay and Android Auto and the system now features over-the-air updates and Genesis Connected Services functionality.

The digital climate panel is responsive and very simple to operate, which is handy when on the go. The 12.3-inch digital instrument cluster is semi-customisable and it’s handy that the 8.0-inch coloured head-up display pulls through satellite navigation directions and traffic sign information. 

The G70 3.3T Sport Luxury sedan on test here is priced at $88,000, before on-road costs, which is $7000 more expensive than the 2.0T Shooting Brake version. That positions it right in the middle of its nearest competitors and you get some fab features included. 

The premium items include electric front seats with heat and ventilation functions, heated rear outboard seats, Nappa leather upholstery and other leather trims, a sunroof, a heated leather-wrapped steering wheel and a premium 17-speaker Lexicon by Harman sound system.

The update sees the G70 now have an intelligent speed limit assist feature, the 'Genesis Connected Services' app and over the air updates to its software.

Other standard features include keyless entry, keyless start, remote start from the key fob, a powered tailgate, 19-inch alloy wheels, a temporary spare wheel, dual-zone climate control and extendable sun visors.

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.

The G70 3.3T Sport Luxury sedan has a 3.3-litre V6 turbo-petrol engine with a maximum power output of 274kW and 510Nm of torque. The G70 sedan is a rear-wheel drive and features an eight-speed auto transmission.  

The V6 engine responds eagerly, being able to do a 0-100km/h sprint time in just 4.7-seconds. Suffice it to say it’s fun to drive.

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.

The compromise for getting all of the power is that she’s a thirsty gal and the official combined cycle fuel consumption figure is 10.4L/100km and my real-world usage came to 10.6L/100km.

However, that’s after mostly doing open-roading – expect the fuel usage to be higher in an urban setting.

Based on the combined cycle and the 60L fuel tank, expect a driving range of around 577km on average. Which means you’ll be filling up more on a longer journey than more efficient sedans.

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 G70 sedan is a lovely car to drive with graceful handling and a good well of power to dip into.

That oomph is there when you need it and it’s as easy to drive in the city as it is on the open-road.

The responsive steering makes the G70 sedan feel nimble and well-balanced in turns, even when you accelerate out of a hair-pin corner.

The suspension is on the firm side and that can lead to a few grunts when you hit bigger bumps but the ride is not unpleasant, even for back-seaters. 

The cabin is generally quiet but you can get road/wind noise at higher speeds. It’s not enough to intrude on chatting but you don’t forget it’s there, either.

The G70 sedan is easy to park because it has an outstanding 11m turning circle. The 360-degree camera system is clear and the front and rear parking sensors make light work of a tight car park.

The Genesis G70 has a great suite of safety features and it’s almost a case of what doesn’t it have.

But a real highlight is the blind-spot view monitor which pops a video feed of your blind spot onto your instrument cluster. Very handy to have in a city setting!

The G70 has a maximum five-star ANCAP safety rating from testing done in 2018, with the update now featuring 10 airbags, which is fantastic for the class.

Other standard safety features include blind-spot monitoring, blind-spot collision avoidance assist, driver attention warning, forward collision warning, lane keeping aid, lane departure alert, rear cross-traffic alert, rear occupant alert, adaptive cruise control with stop and go function and a tyre pressure monitoring system.  

A clear 360-degree camera system as well as front and rear parking sensors also come standard.

The G70 has AEB (operational from 10–180km/h) with pedestrian and cyclist detection.

There are ISOFIX child seat mounts on the rear outboard seats and three top tether anchor points but only two child seats will fit. Front passenger comfort may be compromised for front occupants when a 0-4 rearward facing child seat is installed.

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.

The Genesis after-purchase program is hard to beat and such a treat because you get five years or up to 50,000km complimentary servicing with the G70. How good is that? 

The G70 also comes with a five-year/unlimited km warranty and the servicing intervals are every at 12-months or 10,000km, whichever occurs first. The interval could be annoying if you travel a lot but any annoyance will be softened by the fact that the services are free.
