Mazda BT-50 vs Mercedes-Benz C350 E

What's the difference?

Key to the success of the BT-50 XS will be acceptance by fleet buyers. The vehicle, however, seems to be pretty well considered as far as that goes, although as with any stripped-down model, there are features that will be missed. Things like the manual air-conditioning probably won’t make much difference, but the lack of a tyre pressure monitoring system is a bigger issue for a working vehicle. Performance from the smaller engine is still well within acceptable parameters, but we reckon any buyer considering using much of the 3500kg touring capacity would be better off with the 3.0-litre engine offered in the rest of the BT-50 range.

The Mazda is not the best riding of its ilk, and there are competitors with bigger cabins, although, notably, at this point on the pricing ladder, these are often from China rather than Thailand where the Mazda is built. Ultimately it will come down to whether the smaller engine and reduced performance is an issue and also whether the money saved over the bigger-engined BT-50 is enough to justify that and the loss of some creature comforts. But since fleet managers are notoriously hard-nosed about this stuff, there’s a good chance to BT-50 XS will find a market.

Plug-in hybrids will probably not appeal to all buyers, but in the premium space they make sense.

Smooth electric driving paired with the potential for weekend trips outside the 100km-or-so range make the C350e a decent thing, let alone its price parity with the C300.

It still doesn’t top the charts for value or practicality, but even aside from the PHEV tech, the C350e remains a fun-to-drive sedan that holds its own in the executive space.

Targeting tradies and fleet customers has meant Mazda has embraced the concept of factory accessories. Right now, there are options for tougher front bumpers, bull-bars, snorkels, drop-side trays, an awning, wheel-arch flares (for bigger, aftermarket wheel and tyre packages) driving lights, roof racks, canopies, tub-drawer systems and even a dual battery set-up. All these factory options carry the full Mazda warranty.

But Mazda has gone even further with accessory packs aimed directly at different fleet markets. For instance, there’s the Mine-Spec Pack which incorporates a park-brake alarm, high-mounted brake lights, a reversing buzzer, work-lights, LED rear lighting and pre-wired switches for auxiliary and beacon lighting.

Externally, Mazda's design brief for the BT-50 has clearly been to not frighten the horses. But it's better than that, because it has actually emerged as one of the better looking utes out there. In XS trim, even the steel wheels add a no-nonsense flavour to the overall effect. And where some of the competition appear to be trying very hard to ape the full-sized US-made pick-ups, the Mazda is its own thing.

Inside, the smaller info screens and simple layout in basic black tell the budget story. At the same time, there's a lot to like in terms of the clear, simple analogue gauges and the no-fuss controls including the conventional T-bar, park-brake and ignition key. There's a look and feel that also suggests this is a ute that should be able to take a few knocks in the course of earning a living.

The C350e doesn’t depart massively from the familiar visual formula that is the current ‘206’ generation C-Class and that’s no bad thing.

Call it conservative if you like, but having seen what’s possible when Mercedes takes risks (hello EQ models), the traditional Mercedes design language is put into healthy perspective. 

Handsome proportions and lines without any fuss - there are no unnecessary creases or panels or materials.

The plug-in C350e comes, as mentioned, with the AMG Line pack, adding 18-inch five-spoke AMG wheels, an AMG front apron, grille insert, and of course EQ Hybrid badging.

The pack also includes AMG Line styling inside, where you’d have to be a Mercedes regular to spot the specifics. The AMG-style steering wheel and seats are the biggest giveaways.

With a choice of cab-chassis of pick-up tub, not to mention the option of a single or dual-cab body in cab-chassis form, the XS allows for a fair bit of creativity in how it’s configured. The cab-chassis, for instance, will accept a conventional drop-side alloy tray or any number of service body configurations right up to camper bodies.

The stock tub on the pick-up version gets a drop-in liner but there’s no power outlet or light that some of the competition offer. The tie-down points are also a bit disappointing with two lower points in the rear of the tub and a pair of higher points in the front. Experience tells us that high-mounted tie-down points are vastly less practical than anchor points mounted close to the cargo floor.

The move to the larger engine has, however, increased the Mazda’s towing ability. From the previous version’s 3000kg towing limit, the new 2.2 can now legally tow 3500kg (with a braked trailer and approved tow-hitch). Payloads vary according to specification, but range from about 1000kg right up to 1379kg for the XS singe-cab-chassis.

The factory-option drop-side tray carries it’s load up high, but offers a flat floor with no wheel-arch intrusions. The standard tub is not as large in any direction, but does have a damped tailgate for safety (you can’t drop it) and convenience (the gas struts help raise it).

In the cabin, you get USB charging ports (two in the front, one in the rear seat) and there are central air-vents for the rear seat of dual-cab models. The dual-cab also has an under-seat storage area, two gloveboxes and a 60/40 split fold rear bench. The doors feature bottle holders and there’s a flip-down glasses compartment in the roof lining.

While the front seats are comfy enough for bigger drivers, the rear seat also goes against dual-cab tradition a little by having plenty of room in every direction, as well as a rational seat-back angle.

The space inside the C-Class remains straight-forward as ever. The layout and features don’t stray from convention, meaning there’s a sizable central screen, digital driver display, central cupholders, and places to put things like a phone, with wireless charging included.

The electrically adjustable seat and steering column make getting into a comfortable position easy, and the memory settings keep it that way.

While physical buttons are scarce, the key controls are easy to access via the central multimedia touchscreen and there’s a lack of complicated sub-menus. It's a refreshingly straightforward system compared to some from rivals, especially that of former category benchmark BMW.

There are fewer than a dozen main tile buttons on the menu, and they’re clear and easy to work out. The main screen also defaults to the navigation, and the climate controls are always visible on the touchscreen.

The central storage area is laid out so a phone sitting in the charging pad is slightly hidden, meaning it’s not a distraction, plus the cover means the cupholders and storage can be hidden away. Tidy!

The AMG-style steering wheel’s haptic controls can be used as regular buttons, but more than once on the test drive I nudged the volume and turned my music back on, just a minor annoyance.

In the second row, there’s generous space for a mid-size sedan, and the seats are comfortable for an adult to ride along for a lengthy trip.

There’s a centre armrest, hidden cupholders, and a generally light and open feeling thanks to the panoramic sunroof.

The battery for the hybrid system sits under the second row seats, which means there’s no uneven flooring in the 315L boot.

The Mercedes-Benz C350e kicks off from $98,200, that’s before options and on-road costs.

And there are some key options, the main one being the ability to DC fast-charge which costs $1500 and brings the total to $99,700.

Pricing sits par with the C300 non-PHEV because of its similar specification, and Mercedes Australia said it wanted to give buyers the choice of internal combustion engine (ICE) or PHEV without having to consider the costs.

There’s a decent stack of standard kit in the C350e, including power adjustable heated leather seats, a 12.3-inch multimedia touchscreen and same-size digital driver display, head-up display, and wireless Android Auto and Apple CarPlay.

The C350e also scores some more fun stuff as standard, including a Burmester surround sound system, panoramic sunroof, the Driving Assist Plus pack, augmented reality MBUX, and the AMG Line pack which adds some sportier-looking design features.

It also comes with Mercedes’ Comfort Suspension which includes self-levelling suspension, and Digital Lights with adaptive high beam.

The new engine capacity of 2.2 litres is up from the 1.9 of the previous XS version but still well short of the 3.0 litres of the more expensive BT-50 versions. And the specifications are pretty much exactly what you’d expect with the new 2.2 just about splitting the difference between the old 1.9 and the 3.0.

In this case, that equates to 120kW of power and 400Nm of torque, while the 1.9 was good for 110kW and 350Nm, and the 3.0 sports 140kW and 450Nm. So, yep, somewhere right about the middle. And that makes sense given the new 2.2 uses the basic mechanical architecture of the 1.9.

But the switch up to the new engine brings one very important change and that’s the adoption of an eight-speed automatic to replace the six-speed unit fitted to the previous XS and the other BT-50s. That has an obvious potential benefit for drivability, but also for fuel economy.

Mazda has also added stop-start tech to the XS in the name of efficiency. But, as we’ve found many times before, the fuel economy benefits seem restricted to the official test results rather than the real world where this technology serves to annoy many drivers more than anything else.

If you opt or the four-wheel-drive variants, you’ll get a rear diff lock but you miss out on an on-road 4x4 setting. Considering the 2.2-litre’s newfound towing capacity (the full 3500kg of the competition), that lack of a 4x4 Auto setting is a shame, but not an unexpected one at this price-point.

The C350e’s plug-in hybrid drivetrain consists of a 2.0-litre turbo-petrol four-cylinder engine and an electric motor that drives the rear wheels via a nine-speed automatic transmission.

The combustion engine’s peak outputs are 150kW and 320Nm, while the 95kW/440Nm electric motor works with it to land on a total system output of 230kW and 550Nm.

While it’s not lightning quick, the C350e has a decent claimed 0-100km/h sprint of 6.1 seconds, and from the driver’s seat it certainly feels brisk enough to get out of its own way.

While one of the expected benefits of the 2.2-litre engine compared with the three-litre unit is a reduction in fuel consumption, the new 2.2 engine goes one big step further by actually being more frugal than the 1.9-litre engine it replaces. Well, in terms of the official government test, anyway.

The single cab-chassis model in new 2.2-litre, two-wheel-drive form posted a combined (urban-highway) fuel number of a creditable 6.9 litres per 100km. Compared with the mechanically similar 1.9 single cab-chassis, that’s a saving of 0.1 litres per kilometre, and a corresponding drop in tailpipe carbon emissions of 1 gram per kilometre.

To be honest, this small improvement is probably largely due to the stop-start system now fitted, which many drivers will turn off at the first opportunity. Even so, the new eight-speed transmission must also be playing a part, so let’s call the old and new engines line-ball in the real world.

The rest of the XS line-up scored official figures of 6.3 litres per 100km for the double-cab pick-up 4x2, 7.1 litres for the double cab-chassis 4x4 and 6.6 litres per 100km for the dual-cab pick-up 4x4.

With the BT-50’s standard 76-litre fuel tank, the theoretical range is more than 1000km. In reality, that’s going to be closer to 800km.

The BT-50 engines do not require AdBlue additive to reduce exhaust emissions.

Mercedes officially claims the C350e has a driving range of 104km under NEDC testing, with a 25.4kWh battery supplying the juice.

Official fuel use is just 1.5L/100km, but Mercedes says that becomes 7.6L without any battery charge to help it out.

Under standard 11kW AC charging, it’s about two hours from flat to full, but with the optional 55kW DC fast-charging, it takes about 20 minutes from flat to 80 per cent.

Striking the right balance between ride comfort and load-lugging capacity has always been the big trick with utes in general. The fact is, there’s probably no ideal setting, especially considering the range of payloads a ute can be expected to carry on any particular day. In the BT-50’s case, Mazda has opted to go for a stiffer suspension tune. That means it can technically tow and haul with the best of them, but it also dictates that ride quality is far from what you’d call plush, even in this market segment.

The ute handles bumps best when the undulations don’t come too hot and fast. But strike a patch of high-frequency lumps and bumps and the suspension, particularly at the rear, starts to pogo about with a corresponding decline in ride control. The steering, too, seems to lack a little feel and is relatively slow-geared (although that has its benefits off-road).

The engine certainly does the job in isolation, but it’s likely to struggle a little with the full three-and-a-half tonnes on the hitch. It’s pretty noisy, too, and definitely sounds like a diesel, unlike some modern diesel designs that are more refined. There’s also a sense that Mazda has ditched some of the sound deadening of other BT-50 models, as the engine is certainly heard and felt. The optional snorkel moves the induction noise right into the driver’s window when it’s open, too.

But the new eight-speed automatic transmission is a beauty. Upshifts are crisp and smooth and even the downshifts as you approach a full stop are measured and calibrated to never intrude. And it’s nice to see a conventional T-bar shifter with no separate park button or non-intuitive movements required.

We didn’t get a chance to try the BT-50’s off-road chops, but past experience tells us that the Mazda will be pretty good. As with many four-wheel-drive utes, the limiting factor will be the standard tyres fitted at the factory.

The C350e has a few drive modes that are mostly self-explanatory, those being Battery Hold, Electric, Hybrid, Sport and Individual.

You’ll likely find yourself using Electric and Hybrid most of the time, so we’ll focus on those. Sport is fine but somewhat defeats the purpose of the plug-in system for day-to-day driving.

In electric mode, the C350e doesn’t feel like it’s lacking any power without the engine helping it along. Acceleration is smooth, brisk enough, and a 130km/h top speed means you won’t need the engine on your commute.

Realistically, its 104km range is probably somewhere closer to 80km, but covers you for a decent daily distance.

Let the car use the engine to help out via Hybrid mode and, if you’ve got music playing, you might not notice the engine starting and cutting. The system is smooth and it means a much longer life out of the battery before needing to charge. That, and there’s the benefit of more brisk acceleration thanks to the hefty 230kW/550Nm total outputs.

Everything else about the C350e is classic C-Class - the ride is controlled and the suspension does a decent job of soaking up bumps and rough roads, the comfort and self-levelling suspension makes cornering smooth and inspires confidence.

The most noticeable shortcoming for the car is its transmission hesitation if you put your foot down quickly, though the ability to use the paddles to choose your own gears in Sport mode avoids this.

In Electric or Hybrid, the paddles decide how much braking regen to apply, a useful feature that lets you recuperate some power for the battery if your drive includes a lot of downhill slopes or if you’re avoiding relying on the brake pedal.

The C530e’s extra weight doesn’t dull its driving characteristics as you might expect from a car laden with PHEV tech, so it’s a welcome surprise that you could pick up a plush plug-in for the same price as a combustion C300.

The C-Class has a five-star ANCAP rating, but it was tested in 2022 before the plug-in variant arrived.

Still, 10 airbags and an advanced list of safety features provides peace of mind.

The C-Class benefits from the brand’s Pre-Safe collision protection system to minimise occupant injuries from an impact, even to your hearing.

It also has emergency collision avoidance via steering input, driver monitoring, speed limit assist with adaptive cruise control, and parking sensors with surround-view cameras.

Mazda’s standard five-year/unlimited-kilometre warranty applies to the BT-50 range, and includes the first five years of roadside assistance, too.

Service intervals are every 12 months or 15,000km, whichever comes first. Capped-price servicing is available with the first five years of servicing costing $2188 on 4x2 versions and $2302 for 4x4 variants.

It’s worth mentioning that the BT-50’s new engine is Euro 5 compliant but doesn’t require AdBlue, reducing running costs.

Mercedes has a five-year, unlimited kilometre warranty which is decent for a premium brand.

Servicing is pricey, though. 

A three-year pack covering a service every 12 months (or 25,000km, whichever comes first) costs $3355, that being just three services.

Four years costs $4630, or five includes a more expensive service and brings the total to $6890. That’s an average of $1378 per service.

Finding somewhere to spend that money shouldn’t be hard as there are 100 dealers listed in Australia.
