Hyundai Genesis vs Mercedes-Benz CLA-Class

What's the difference?

The Genesis is not quite a match for cars twice its price but it makes you think what's possible. It doesn't have the dynamic brilliance of a BMW or the self-assured faultless execution of a Mercedes. Lexus ought to be worried, though - why would you have an LS when you could have this? The only answer is 'badge'.

The Genesis is an epoch-making car for the Korean manufacturer. As the company has got better, there are fewer excuses for overlooking it. While the Genesis is pitched into a shrinking market, it's not really meant for the average i30 buyer to buy, but to see.

It's bristling with tech and is not only a halo car but a shot across the bows of both Lexus and the Germans. Attached to that shot is a note: "We're coming for you." In other words, Hyundai got it right.

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.

The Genesis is like no other Hyundai. For a start, it's gigantic - it looks easily as big as a BMW 7 Series (it isn't) with the road presence to match. There's a lot of BMW from most directions, but with a sharper approach to the creasing and character of the sheet metal.

Towards the rear it's more BMW 6 Series Gran Coupe and is all the better for it. The style is understated and technocratic.

Inside is also very Germanic, but with a bit more of a Lexus feel

The big wheels from the Ultimate pack help make it look lower and sleeker, too.

Inside is also very Germanic, but with a bit more of a Lexus feel. Our car had the lighter leather which meant that the wood and the metal materials didn't necessarily work well together.

The interior is expertly put together and feels like it will last forever.

The only jarring moment is the gear selector is shared with our long-term Hyundai i30 - it looked a bit cheap in what is otherwise a beautifully executed cabin - it needs more heft.

On Australian-delivered cars there is just one Hyundai badge, sitting proudly on the boot - you get the feeling this was debated long and hard and when the decision was made to go for it, a big one was chosen.

However, the winged Genesis branding takes pride of place everywhere else. When you approach the car at night and the puddle lamps come on, the Genesis logo is projected on to the ground, crisp and clear.

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.

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 Genesis is powered by Hyundai's own 3.8-litre V6 developing 232kW and 397Nm, mated to Hyundai's eight-speed automatic transmission.

Despite weighing just under two tonnes, the Genesis completes the dash to 100km/h in 6.5 seconds.

It has a claimed 11.2L/100km on the combined cycle. In what must be a first, we got below that, averaging 10.8L/100km over two weeks. And that's without stop-start fuel-saving to blunt the effect of lot of city driving.

The Genesis is not going to tempt you into a track day, even with rear wheel drive

We'd still like to try the V8 - only available in left-hand drive markets - though.

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.

At five metres long, with a ride firmly pitched in the luxury camp, the Genesis is not going to tempt you into a track day, even with rear wheel drive.

Blindfold your passengers and swap them between a Lexus, a BMW and a Genesis and the overwhelming impression they'll get is one of incredible smoothness.

If you're wanting sudden movements, this isn't the car for you

Sitting in the back of the Genesis, it's easily as good as the German and luxury Japanese competition. The seats are hugely comfortable, there's ample head, leg and shoulder room and it feels lot nicer than anything within a bull's roar of its price.

No matter where you sit, it's an incredibly quiet car. The engine is a distant whoosh, the tyre noise muted and there's almost no wind or ambient noise. It's supremely comfortable and the excellent stereo will wash away what little noise does invade.

It certainly feels its weight from the driver's seat, with a competent, soft turn-in, but if you're wanting sudden movements, this isn't the car for you.

The Genesis is an epoch-making car for the Korean manufacturer

On fast flowing roads you can have some fun, but things will get floaty and that will quickly kill that fun. The ride and isolation from the rest of the world is completely worth it.

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.
