Mercedes-Benz CLA-Class vs Maserati Quattroporte

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.

Beauty is way more than skin-deep in the Quattroporte and while the 330 doesn't have the punch of the S, it's hardly that much slower. Maserati reasons you will want to spend the $25,000 saved on options, concentrating on the Italian craftsmanship rather than the outright performance available in the V8 or the efficiency of the less aurally attractive diesel.

As with any car of this type, you've got to want one in the first place, but for a big, beautiful sedan, there's nothing as good looking this side of an Aston Rapide. The Quattroporte 330 does nothing to dim the allure of Modena's big mover and, if you're that way inclined, nobody on the outside will ever know.

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.

Long, flowing lines mark out the Maserati as something quite different to its German, British and Japanese competition. This Quattroporte has increased in every dimension but the lines cover its size beautifully.

Big wheels, long wheelbase, low ride but it still looks like a sedan rather than pretending to be a coupe.

The elegance of the lines is complemented by a distinct lack of bling – there's little in the way of chrome work or shouty details. There's plenty satin finishes available and the beautiful paint, while available in pretty much any colour you like, is best kept to a restrained, deep hue. Or silver.

The cabin will doubtless age well. Classic shapes house a fairly conventional but hugely comfortable cabin. The front seats have heaps of adjustment and are large but supportive. Naturally, the leather is soft and supple.

The central screen isn't the dominant feature, like a 50-inch LCD screen in a small living room while buttons are kept to a minimum.

The rear seat is sensationally comfortable, with hectares of available space and a seat comfortable for either lounging or working.

The current Quattroporte has been with us now for a couple of years in diesel and petrol turbocharged V6s and turbo V8 forms.

The 330BHP uses the same, Ferrari-built V6 but detuned to 'just' 330 bhp. The price has been detuned too, dropping $25,000 from the V6 S's entry price to kick off at $210,000.

Maserati 330bhp benefits from an overall specification improvement across the range, landing in your garage with a ten-speaker stereo with USB and Bluetooth, power everything, dual-zone climate control, keyless entry and start, front and rear parking sensors with reversing camera, cruise control, sat-nav, auto headlights and wipers, double glazed windows and an interior covered in leather and wood.

Only very occasionally does it become clear that Maserati is part of the Fiat Group and that moment comes when you use the 7.0-inch central screen in the dash.

The software is based on the group's UConnect and it isn't great. It's not bad, but it feels its age (however, it's much better than the system on the Gran Turismo), needing a lot more work or a quick surrender to Apple's CarPlay or Android Auto.

Once you work your way through the weird menus, it's fine to use and is miles ahead of the not-much-cheaper Lexus LS unit which is almost unusable.

Sound from the ten speaker stereo is crystal clear and the phone performance is also very good.

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.

Like the S, the 330bhp is powered by Maserati's twin turbo 3.0 litre V6, made with more than a dash of Ferrari involvement. As the name suggests, it produces 243kW and a chunky 500Nm. With just under two tonnes to shift, the ubiquitous eight-speed ZF automatic transmission whisks the Quattroporte 100km/h in 5.6 seconds, only half a second down on the 301kW V6 S.

Maserati claims 9.1L/100km on the combined cycle (with the help of stop-start), which seems reasonable given our figure of 10.8L/100km, which we got a with a mix of city and highway running as well as a very enthusiastic blast through some secret back roads.

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.

Just a few hundred metres behind the wheel is all it will take to convince you the Maserati belongs in the same class as the competition. It's incredibly quiet – courtesy of the acoustic double glazing – and all occupants benefit from supreme comfort.

While the 330 is 58kW down on the full fat V6, you won't really miss them. There's a fat torque curve, with all 500Nm available from 1750 to 5000rpm, meaning easy progress for the 5.2 metre sedan.

The Quattroporte has two sport buttons to choose from – one looks after the drivetrain and exhaust valving while the second stiffens up the Skyhook suspension.

With the first sport button pressed, you get a more lively throttle, sharper shifts and a glorious noise from the exhausts, although they are a long way from your ears.

It's still a fast car, with strong acceleration from standstill and in the gears, the power as linear as you like with no real turbo lag and a most un-turbo noise to go with the performance.

The only dynamic problem is the electric steering – it seems to get confused between your inputs and feedback from the road, the tyres feeling like they're 'nibbling' an uneven surface, tweaking the wheel in your hands. 

The assistance is a little spotty, too, unexpectedly changing weight. It's just a bit weird. In normal driving, you'll never notice it.

Six airbags, ABS, stability and traction controls, brake assist, blind spot monitoring and rear cross traffic alert.

There is no ANCAP or EuroNCAP safety rating for the Quattroporte.
