Mercedes-Benz C43 vs Peugeot Boxer

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.

It has its faults like any vehicle but it’s a competent all-rounder, that combines sub-$50K pricing with a big payload capacity, mostly user-friendly design, improved safety and a compelling warranty. It also faces stiff competition in the 3501-8000kg GVM class, particularly from rivals with an automatic option. 

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.

It comes ready for work with hard-wearing black plastic in the most vulnerable places for scrapes and dents, including the front and rear bumpers and down the sides. The same black finish can be found on the window surrounds, door handles, huge door mirrors (which would not look out of place on a Kenworth) and the housing for the high-mounted third brake light.

It’s a large vehicle measuring 5413mm long, 2050mm wide and, thanks to the conspicuously high roof line, stands 2522mm tall. So, like numerous rivals in this weight class, it can’t access most shopping centre and underground carparks.

The front-wheel drive chassis, with its 3450mm wheelbase and 12.6-metre turning circle, features a simple and rugged combination of coil-spring strut front suspension, four-wheel disc brakes, power-assisted rack and pinion steering and single-leaf/solid beam rear suspension. Long rubber bump-stop cones, attached to the underfloor above each end of the rear axle, provide extra support when the springs compress under heavy loads.

The steel bulkhead, which separates the cabin from the cargo bay, insulates the driver/passenger from cargo bay noise and doubles as a robust cargo barrier. Its window is large enough to allow the driver to make a quick over-shoulder glance at any time to check the load is secure.

Criticisms? The relatively small 5.0-inch media screen can make the reversing camera’s vision difficult to see in detail. The height adjustment on the driver’s seat, using two levers on the lower right side, is clunky to operate. And although the rear barn-door windows are heated, there are no wiper/washers, which we didn’t get to test in wet conditions, which is most unusual for Melbourne.

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 Boxer 160’s 1865kg tare weight and 3510kg GVM results in a sizeable 1645kg payload rating. However, we always quote kerb weights (full tank of fuel) rather than tare weights (10 litres of fuel) to keep things consistent.

So, in this case, adding the missing 80 litres of diesel (67kg) results in a kerb weight of 1932kg, which reduces the payload by the same amount to 1578kg. That’s still almost 1.6 tonnes which is more than ample for this category. It's also rated to tow up to 2500kg of braked trailer and, based on European figures at least, can do this with a full payload.

The cargo bay provides a competitive 11.5 cubic metres of load volume and 10 sturdy load-anchorage points. Its floor, which is 3120mm long and 1870mm wide with 1420mm between the wheel housings, can  accommodate two 1165mm-square standard Aussie pallets or three 1200 x 800mm Euro pallets. There’s ample forklift access through the rear barn-doors with full 270-degree openings or sliding side doors with their big 1250mm openings.

The high roof cavity means even tall adults can stand inside with headroom to spare. It also provides a large and very useful open storage area over the driver’s cabin, which is ideal for storing ropes, straps, load-padding and any other gear a hard-working van might need.

Although the side doors and barn-doors are lined to mid-height, the cargo bay walls are unlined which leaves numerous cavities exposed that could make small items like pens, keys, phones etc disappear if they were dropped. The load floor is also unprotected.

Cabin storage options include upper and lower bins in each door, with the lower bins being wide and deep enough to hold several large bottles. There’s also a full-width map shelf that sits about forehead height for tall drivers, which is easy to access and can hold heaps of stuff.

The dashboard also has numerous storage choices including open shelves to the right of the steering column and underneath it, cup/small-bottle holders in the centre of the dash and on top a fixed clipboard with spring-loaded clamp. There’s also a glovebox with another large open storage bin below it plus even more storage, about the size of a baking tray, under the driver’s seat.

The Boxer 160 (which denotes its European horsepower or ‘PS’ rating) is available only with a 2.0 litre turbo-diesel engine and six-speed manual transmission, plus a choice of 4035mm long wheelbase or 3450mm standard wheelbase like our test vehicle, for a list price of $47,490.

It comes equipped with 15-inch steel wheels and 215/70 R15C tyres with a full-size spare, plus cargo bay bulkhead, hard-wearing rubber floor, 12-volt accessory socket and USB ports, height/reach adjustable steering wheel, two bucket seats with fold-down inboard armrests and lumbar adjustment and multimedia system with 5.0-inch touchscreen and sat-nav plus ample storage and more. There’s also AEB on the upgraded safety menu.

The only options available are three paint colours (Imperial Blue, Red and Aluminium Grey) in addition to our test vehicle’s standard Bianca White.

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 2.0-litre Blue HDI four-cylinder turbo-diesel engine, which meets the toughest Euro 6 emissions standard using AdBlue, produces peak values of 120kW at 3500rpm and 310Nm of torque at 1500rpm.

Peugeot claims this engine was tested for more than 10,000 hours, subjected to more than 1.3 million km of drive-testing and 16,000 thermal shock cycles (cold starting and accelerations), corresponding to 15 years of intensive use. In short, it should be tough enough. Transmission is a sweet-shifting six-speed manual.

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.

Peugeot’s official combined average is a fanciful 6.4L/100km. The dash readout was claiming a more realistic 9.0L/100km when we filled the tank after 282km of testing, which included more than a third of that distance lugging its maximum payload.

However, our own figure calculated from fuel bowser and tripmeter readings came in at 9.9L, which is more than 3.0L/100km above the official figure. Even so, sub-10L economy is very efficient  for a vehicle of this size, so based on our figures you could expect an excellent real-world driving range of around 900km from its big 90-litre tank.

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.

You sit up high with the huge windscreen providing a commanding view of the road ahead. Clear eye-lines to the large door mirrors (with wide-angle mirrors in their lower thirds) provide ample coverage of side and rear traffic.

Vision through the central rear-view mirror is also relatively clear compared to the cluttered views found in numerous rivals we’ve tested. The join of the barn-doors obscures the mirror’s central portion, but the driver still has a good view of what’s behind.

The fold-down inboard arm-rests combined with the door contours provide balanced support for arms and elbows to reduce strain on neck and shoulders. This support is particularly good for the driver, as it also allows your hands to rest comfortably on the steering wheel.

There’s negligible cargo bay noise thanks to the bulkhead. However, engine noise is noticeable and tyre noise can be quite intrusive, particularly at highway speeds on coarse bitumen surfaces. Cruising in top gear results in a fairly relaxed 2100rpm at 100km/h and 2300rpm at 110km/h.

The engine, with maximum torque at 1500rpm, has good all-round performance and pulling power under heavy loads, but lacks the sharper throttle response of some rivals. Even so, the manual gearshift has a light but well-defined action combined with a light clutch pedal weight.

Steering is nicely weighted and the quartet of disc brakes have plenty of bite. Handling and stability are also good regardless of load. The rear suspension tuning is commendable when running without loads on bumpy roads, providing a surprisingly smooth ride given spring rates that are designed to cope with 1.5 tonne-plus payloads.

Our only gripes are that the driver’s seat’s adjustable lumbar support presses too firmly against the spine for our liking, even on its softest setting. We also detected a couple of rattles and squeaks on bumpy roads, which sounded like they were coming from the dashboard area.

There’s no ANCAP for this vehicle segment but the Boxer would probably score well if there was thanks to the latest features like video autonomous emergency braking, forward collision warning, lane-departure warning, LED daytime running lights, reversing camera, rear parking sensors and more. There’s also driver and passenger front and side-curtain airbags.

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 Boxer is covered by Peugeot's five years/200,000km warranty and scheduled service intervals of 12 months/20,000km, whichever occurs first. Capped-price servicing applies for the first five scheduled services with a total cost of $3445 valid until June 30, 2020.
