Fiat Ducato vs Mercedes-Benz CLA35

What's the difference?

The latest Fiat Ducato, in MWB MR configuration with optional nine-speed auto, is a competent competitor in the 3501-8000kg GVM segment. Its class-leading two-tonne-plus payload rating would have considerable appeal for those who need to carry exceptionally heavy loads and we couldn’t find any major flaws in its design and performance. However, the warranty is short and there are niggling issues in terms of driver comfort, which if addressed would increase the Ducato’s appeal.

Is the Mercedes-AMG CLA 35 the perfect choice in the sleek sedan’s line-up?

Well, if you are after outright performance, then the answer still clearly lies with the CLA 45. But for those that just want a little more pep compared to the standard CLA range, the 35 is undoubtedly the one to get.

It’s not without its flaws, though, commanding a $15,000 price premium over the CLA 250 and a tougher-than-we’d-like ride, but if you value a more engaging drive and a brisk 0-100km/h time, the CLA 35 should definitely be on your shopping list.

The MWB MR's front-wheel drive chassis rides on a 3450mm wheelbase with 12.5-metre turning circle. It’s 5413mm long, 2050mm wide and 2539mm tall, so like numerous van rivals in this GVM class it can’t access shopping centre and underground carparks which typically have a 2.2-metre height limit.

Underpinnings are simple and rugged, combining coil-spring strut front suspension with a leaf-spring rigid-tube rear axle that’s well designed for heavy load-carrying, with compressible rubber cones between body and axle that provide a second stage of support. There’s also four-wheel disc brakes, power-assisted rack and pinion steering and ample hard-wearing black plastic protecting the most vulnerable areas of the bodywork from scrapes and dents.

A sealed steel bulkhead separates the cabin from the cargo bay, insulating driver and passengers from load area noise and doubling as a robust cargo barrier. Its sliding window is ideally positioned to allow the driver or passenger to make a quick over-shoulder glance to check that their load is secure. Leg room for the centre passenger is unusually generous, even for tall adults, which would be appreciated by a crew of three.

Interestingly, the rear barn-door windows are heated but there are no wiper/washers fitted. At first this appeared to be an oversight, but having driven the Ducato in heavy rain we were surprised at how spray-free the rear screens remained and how clean they were afterwards.

Our only gripes are that the driver’s left footrest is so short you can only rest your toes on it. It’s a shame the excellent full-length one that resides in the passenger footwell (which of course is the driver’s footwell in LHD models) can’t migrate across the cabin for RHD versions. Driver comfort would be further improved with more rake adjustment in the base cushion.

The small 5.0-inch infotainment screen also makes it difficult to see much detail in the vision provided by the reversing camera. The optional 7.0-inch screen would be an improvement here, but is only available as part of the Comfort and Tech Pack.

From the front, the CLA 35 exterior oozes style and luxury.

Up front, the sleek and slender headlights emphasise the width of the fascia, while the large Mercedes logo sits proudly front and centre of the CLA’s nose.

There are subtle hints to the CLA 35’s sportiness too, with a slightly bulging bonnet and chiselled lower chin.

The grille is also unique on the 35, with a dual-horizontal slat design instead of the non-AMG CLA’s diamond pattern or the CLA 45’s Panamericana grille.

To my eye, the front of the CLA 35 is actually a bit too tame in styling for an AMG model. I prefer the in-your-face aggression of the CLA 45’s widened track and front grille, while the CLA 35 opts for more subtle styling cues. To each their own, though.

The silver paintwork of our test car probably doesn’t help, and if it was my choice I'd pick 'Sun Yellow' or 'Denim Blue' to stand out a bit more from the sea of black, grey and white German cars out there.

Move to the rear of the car though, and a large rear diffuser, big dual-exhaust outlets and a bootlid spoiler are much more befitting an AMG model.

Step inside the CLA and you will see it adopts the same dashboard design as all new-generation Mercedes vehicles built on the MFA2 platform, with the 'MBUX' dual-screen layout, large air-vents and central touchpad.

Our car was specced out with red-leather interior, which is a bit too loud for my tastes, but a two-tone black leather/titanium grey combo can also be had at no extra cost.

Sitting inside the CLA 35, you can tell it’s a modern car thanks to the clean layout of all the controls, while the screen-heavy dashboard definitely makes it feel tech-focused.

The Ducato’s 2060kg kerb weight and 4250kg GVM results in a huge 2190kg payload rating which dwarfs rivals we've tested including the Mercedes-Benz Sprinter, Ford Transit and its Peugeot Boxer sibling. It's also rated to tow up to 2250kg of braked trailer but given that Fiat does not publish a GCM (Gross Combination Mass) number, we can’t confirm if it can tow that weight while carrying a full payload.

The cargo bay, with a competitive 11.5 cubic metres of load volume, has an unprotected load floor that’s 3120mm long and 1870mm wide with 1422mm between the wheel housings. Therefore, it can easily carry two 1165mm-square standard Aussie pallets or three 1200 x 800mm Euro pallets, held in place by eight sturdy load-anchorage points.

There’s also ample forklift access through either the rear barn-doors, which can swing open to 270 degrees with a combined 1562mm-wide opening, or the sliding side doors with their 1250mm-wide openings.

All doors and walls are lined to mid-height and the raised roof cavity allows even tall adults to stand inside without stooping. It also provides a large and very useful storage area over the driver’s cabin, which is ideal for stowing ropes, straps, load-padding etc.

There’s plenty of cabin storage too, with large-bottle holders and two levels of storage bins in each front door. The dashboard offers numerous open storage bins plus small-bottle/cup holders, a glovebox, large overhead map shelf and storage tray under the driver’s seat. The centre seat’s backrest also folds forward to reveal a handy work desk on the back of it, complete with a spring-loaded clip to hold documents in place, a pen holder and two more small-bottle/cup holders.

Measuring 4695mm long, 1834mm wide, 1399mm tall and with a 2729mm wheelbase, the CLA 35 is definitely a sizeable sedan in the metal.

This actually makes the CLA 35 slightly longer and wider than a non-AMG C-Class sedan that measures 4686 and 1810mm respectively, but don’t expect the same level of practical interior space.

With a heavily sloped roofline, rear-seat comfort takes a hit. My 183cm (6.0ft) frame could not sit upright behind my driving position without tilting my head, while legroom was also slightly lacking.

With such large C-pillars and a small rear window, the second-row can actually feel a little claustrophobic for full-sized adults, but will seat children quite comfortably.

Second-row amenities include air-vents, two USB-C ports, back-of-seat storage nets, bottle holders in the doors, and two cupholders in the fold-down arm rest.

Just like at a music concert though, the best seats in the CLA 35 are up front, with plenty of room for heads, shoulders and legs.

The cabin is also much more light-filled up front, making for a more pleasant experience.

The front seats are electronically adjustable, as is the steering column, but the headrests are fixed.

Storage options include sizeable door bins, a centre console cubby, glove box, two cupholders and a wireless smartphone charger.

Boot space is 460 litres, but can expand with the rear split-fold 40/20/40 rear seats stowed.

Though the boot looks small and shallow on the outside, the aperture is actually quite large, and can easily accommodate a large suitcase with plenty of room to spare.

Priced at $85,500 before on-road costs, the CLA 35 sits $15,300 upstream of the CLA 250 but is $25,700 cheaper than the $111,200 CLA 45.

Standard equipment includes leather interior, dual-zone climate control, electronically adjustable front seats with heating and memory function, keyless entry and push-button start, 64-colour ambient lighting, and a wireless smartphone charger.

AMG specific appointments include 19-inch wheels, a flat-bottomed steering wheel, sports exhaust, high-performance brakes with silver-painted calipers, blacked-out exterior highlights, sports suspension, a racy bodykit and speed-sensitive steering.

Instrumentation is displayed on a 10.25-inch screen, which can be customised and features AMG readouts.

The multimedia system, which includes satellite navigation, digital radio and Apple CarPlay/Android Auto connectivity, is also outputted to a 10.25-inch screen, with inputs including touch, voice commands, centre touch pad or steering wheel controls.

Our test car also came with a ‘Mojave Silver Metallic’ paint finish and 'Vision Package', adding $1190 and $990 to the bottom line each.

The Vision Package adds LED headlights with adaptive high beams, a panoramic glass sunroof and surround-view monitor.

Straddling the lines between a small- and mid-size sedan, the CLA 35 doesn’t really have any direct competitors, which is reflected in its pricing that slots it between the Audi S3 and S4 sedans.

Though the CLA 35 features a long list of equipment, it is still a sizeable chunk of coin, costing more than the C300 sedan and Volvo S60 T8 PHEV, the latter boasting higher engine outputs.

The all-new drivetrain features Fiat’s latest 2.3 litre four-cylinder turbo-diesel with Multi-Jet 2 electronically-controlled common rail direct injection, variable-vane turbocharging, intercooler and Euro 6-emissions compliance using AdBlue. It produces 130kW at 3500rpm and (in automatic models) 450Nm of torque which peaks at 1500rpm. In case you’re wondering, the red ‘180’ body badges denote European metric horsepower.

The new ZF nine-speed torque converter automatic is a sweet-shifting transmission which Fiat claims is designed to optimise the engine’s torque delivery and fuel economy. It has a sequential manual-shift function if required, which could be useful if hauling big payloads in hilly terrain, but works most efficiently when left alone.

Powered by a 2.0-litre, turbo-petrol four-cylinder engine, the CLA 35 punches out 225kW/400Nm.

Drive is sent through a seven-speed dual-clutch automatic transmissions to the road via Mercedes’ '4Matic' all-wheel-drive system, enabling a 0-100km/h sprint in the 1603kg sedan in just 4.7 seconds. Top speed is electronically limited to 250km/h.

Though I didn’t get a chance to test the latter, the former certainly feels accurate when taking off from a freeway on ramp, however, there is some hesitation from the turbo in getting on boost.

Peak power comes in at 5800rpm, while maximum torque is available from 3000-4000rpm.

Fiat does not publish a combined average consumption figure for the Ducato, but the dash display was claiming 10.2L/100km at the end of our test, which covered almost 300km of which more than a third was with a heavy payload. We also had the auto stop-start function switched off. That consumption figure was very close to our own, calculated from fuel bowser and tripmeter readings, of 10.6L. So, based on our numbers you could expect a real-world driving range of around 850km from its 90-litre tank.

Officially, the CLA 35 sips 7.5 litres per 100km on the combined cycle, but we managed a 9.9L/100km figure in our week with the car.

The majority of our driving was done in inner-city environments, with the two trips down the freeway to seek out twisty country rounds.

Minimum fuel grade in the CLA 35 is 98 RON.

There’s a commanding view for the driver thanks to a panoramic windscreen and clear eye-lines to the truck-sized door mirrors. There’s also reasonable but cluttered vision through the central rear-view mirror, which is partly obscured by the centre seat’s headrest.

The cabin bulkhead is effective in all but eliminating cargo bay noise and engine/wind noise volume is commendably low even on the highway. The highest audible intrusion at those speeds comes from the front tyres, which is acceptable on smooth bitumen surfaces but increases on coarser grades.

Its leather-rimmed steering wheel is nice to use and thanks to the driver’s door moulding and fold-down in-board armrest, there’s evenly balanced elbow support to relieve strain on the neck and shoulders.

The engine and nine-speed auto transmission are well matched, providing energetic performance when prodded and crisp, decisive shifting. Long-legged highway gearing allows 100km/h at 1500rpm (which is also bang on maximum torque) and less than 1700rpm at 110km/h. Ride quality when empty or lightly loaded can get bouncy on bumpy roads, which is not unexpected from suspension with a two-tonne-plus payload capacity.

Our main criticism is insufficient rake adjustment in the driver’s seat base cushion. There’s not enough angle available to stop the driver sliding forwards, requiring constant repositioning that becomes tiring after a while. More rake in the base cushion, combined with a decent-sized left footrest, would solve this issue.

Also annoying is the audible lane-departure warning, which is too loud and sounds like you’re being zapped by a ray-gun in an old sci-fi movie if you step out of line. A less confronting warning would be welcome.

The CLA 35 might not offer the outright thrills or breadth of capability of the CLA 45, but don’t think the cut-price AMG offers up a cut-rate driving experience.

From the driver’s seat, one of the cool things about the CLA 35 is that it doesn’t actually look any different from its more expensive sibling.

The drive-mode selector that is now embedded on the steering wheel is fantastic, a feature first seen on the Mercedes-AMG GT 4-door, and makes changing the driving dynamics on the fly an absolute breeze.

In fact, we think all cars where you can select drive modes should have a selector on the steering wheel like this, which lets you quickly and easily dial it up or down while keeping your hands on the wheel.

'Comfort', 'Sport', 'Sport+' and 'Individual' modes are available, while the transmission can also be put into manual mode independently for those that prefer to use the flappy paddles.

Suspension settings can also be tweaked regardless of which drive mode you are in, and it’s this level of customisability that we appreciate.

You want loud exhaust pops and the engine in full attack with manual shifting and the softest suspension? Sure, that’s doable here in the CLA 35. And toning it down to its most comfortable settings is just a flick of the wrist away.

The steering feels a little numb on centre and at slower speeds, though feedback picks right up with speed and is communicative enough when the road starts to get twisty.

Fitted with wide and sticky Michelin rubber, as well as the aforementioned all-wheel drive system, the CLA 35 is certainly not lacking in grip.

The suspension does an okay job of absorbing bumps, but uneven surfaces, like Melbourne’s tram tracks, can send uncomfortable jolts into the cabin if travelling quickly.

In fact, we think the ride comfort of the CLA 35 is probably its weakest aspect, offering not enough variability in its Comfort and Sport settings, and instead settling somewhere in between, regardless of drive mode.

The CLA 35 is ultimately still a fun and engaging sports sedan, though there are some sacrifices made to get it there.

The CLA 35 has not been tested by ANCAP or Euro NCAP, but the standard CLA range was awarded a five-star rating in September 2019.

Standard safety equipment in the CLA 35 includes autonomous emergency braking, automatic high beams, nine airbags, drive attention alert, blind-spot monitoring with exit warning, lane-keep assist, traffic sign recognition and tyre pressure monitoring.

The standard CLA also comes with these features, and was awarded 96 and 92 per cent respectively in ANCAP adult occupant and child occupant protection tests.

For the vulnerable road user and safety assist examinations, the standard CLA scored 91 and 76 per cent respectively.

ANCAP says the AEB system works from seven-200km/h.

Of note, adaptive cruise control is not standard in the CLA 35 like it is in the CLA 45. Instead, buyers will have to tick the 'Driving Assistance Package' box for the feature, which also comes bundled with cross-traffic alert and lane change assist.

Three years/200,000km warranty looks undercooked compared to the five years/unlimited km offered by some rivals. Scheduled servicing, though, is excellent for hard-working vans at 48,000km/12 months whichever occurs first. Five years of Fiat Professional servicing, based on a total distance of 240,000km, equals $6756.99 or an average of $1351.40 per year.

As with all new Mercedes-Benz models, the CLA 35 comes with a five-year/unlimited kilometre warranty, which is one of the best assurance periods offered by a premium carmaker.

It also comes with five years of roadside assist.

Scheduled service intervals are every 25,000km or 12 months, whichever comes first.

A three-year service plan is available for $2150 for new CLA 35 buyers, saving $500 when priced individually.

Four- and five-year plans are also available, and are priced at $4200 and $4950 respectively.
