Mercedes-Benz C350 E vs LDV D90

What's the difference?

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.

Looking for a cheap, powerful diesel SUV with huge cabin space and a humane third row for adults? The D90 is a really sound offering, especially considering the price of entry for this top-spec diesel which should resonate with Aussies a bit better than the petrol version.

It has plenty of issues that could be ironed out, but they’re all so small and not sale-breaking it’s almost annoying how much better the D90 could be with just a little work. Rivals should be looking over their shoulder for what comes next.

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.

Some colleagues I’ve spoken to like the way the D90 looks. To me, it looks like someone gene-spliced a Hyundai Tucson with a SsangYong Rexton in a lab, then grew it in a stew of peptides and this was the result.

What can’t really be communicated in images is how truly massive the D90 is. At over five metres long, two metres wide and almost two metres tall, the D90 is certifiably huge. Given that’s the case then, it’s admittedly almost admirable that only the side profile makes this thing look a little goofy.

I think LDV has done a pretty good job on the front, and the rear is simple but well resolved for a vehicle that rides on a ladder chassis (just take a look at the Pajero Sport for how ladder-chassis rear designs can get… controversial…).

The wheels, garnishes, and LED headlights are all tastefully applied. It’s not ugly… just confronting… size-wise.

Inside shares some familiar characteristics with sister-brand MG. Look from a distance and it’s all quite nice, get in too close and you’ll see where the corners have been cut.

The first thing I don’t like about the interior is the materials. Apart from the wheel they are all pretty cheap and nasty. It’s a sea of hollow plastics and mixed trims. The faux-wood pattern, which is clearly just a print on a plastic resin is particularly gnarly. Reminds me of some Japanese cars from 20 years ago. It might work for the Chinese audience, but that’s not where the market is in Australia.

On the other hand, you could say “well, what do you expect at this price?” and that is true. Everything is here and works, just don’t expect the D90 to be playing alongside the established players when it comes to fit, finish, or material quality.

The huge screen works to finish the dash, but that darned software is so ugly you’ll wish it didn’t. At least all the major touch-points are ergonomically accessible.

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 D90 is as massive on the inside as it is on the outside. I’m talking better space than a minivan, and nothing says that more than the humane third row. At 182cm tall, I not only fit in the rearmost two seats, but I can do so in as much comfort as any other row. It’s staggering. There’s actual airspace for my knees and head back there.

The second row is massive and on rails too, so you can extend the amount of room available to third-rowers – and there’s so much room in the second row, you’ll have space even with the seats moved forward.

My only criticism here is that the giant rear door is far enough forward to make clambering into the third row a little tricky. Once you’re there though there are really no complaints.

The boot is even usable with the third row deployed, with a claimed 343L of space. That should be hatchback-sized, but the measurement is a little deceptive as the space is tall but shallow, meaning it will only allow you to place smaller bags (a few, if you can stack them) with the remaining space.

The boot is otherwise cavernous with a wild 1350L available with the third row stowed flat, or 2382L with the second row stowed. In this configuration, with the front passenger seat slid forward to its furthest position, I was even able to get a 2.4-metre-long benchtop in the back. Truly impressive.

Without buying an actual commercial van then, this could be the cheapest way into such room, especially in a 4x4 bi-turbo diesel SUV. No arguing with that.

Second-row occupants get their own climate control module, USB ports and even a full-sized household power outlet, with more legroom than you could possibly need. My only complaint was that the seat trim seemed a little flat and cheap.

Front occupants get large cupholders in the centre console, a deep armrest box (with no connectivity in it, just a randomly placed DPF cycle switch), pockets in the doors, and an awkward binnacle under the climate controls that houses the single available USB port. My phone didn’t fit in there.

No complaints about leg and headroom in the front either, though, with plenty of adjustability to boot. The driver’s seat offers a commanding view of the road, although it can be a little unsettling to be so far off the ground in corners… more on that in the driving section.

On paper, the seven-seat D90 is immediately quite appealing. At $47,990, it is literally a lot of car for the money. This latest iteration, the bi-turbo diesel, is only available in Executive trim at this price, but you can pinch pennies further by choosing one of the lesser petrol turbo variants.

Regardless, and much like its MG sister brand, LDV is good at making sure that essential spec boxes are ticked.

This includes screens galore as is popular in the Chinese market, including a massive 12-inch multimedia screen and 8.0-inch digital dash.

A screen is only as good as the software that runs on it though, and let me tell you, the D90’s software is not good. A quick flick through the weirdly small menu reveals barebones functionality, terrible resolution and response time, as well as possibly the worst execution of Apple CarPlay I’ve ever seen.

I mean, it doesn’t even use all of that screen real estate! Not only that, but in a recent overhaul to CarPlay, Apple released software to utilise wider displays – so the car’s own software must simply be incapable of supporting it. Inputs also proved laggy, and I had to repeat myself on multiple occasions to get any use out of Siri. Unlike every other car I’ve used, the software in the D90 wouldn’t return to the radio after you hang up or stop talking to Siri. Frustrating.

I’d rather have a far smaller display that actually worked well. The semi-digital dash was functional, although barely did anything that a small dot-matrix display isn’t capable of and had one screen which for my entire week said ‘loading’. I’m still not sure what it was meant to do…

At least it supports Apple CarPlay at all, which is more than could have been said for segment hero, the Toyota LandCruiser.

The D90 does tick some necessary items that are quite good. LED headlights are standard, as are leather seats with eight-way power adjust for the driver, a heated multi-function steering wheel, 19-inch alloy wheels (which still somehow look small on this huge thing), three-zone climate control, eight-speaker audio system, electric tailgate, keyless entry with push-start ignition, a reversing camera, front and rear parking sensors, tyre-pressure monitoring, as well as a fairly substantial safety suite which we’ll explore later in this review.

Great on paper then, the bi-turbo diesel engine is a boon, as is the fact that the D90 rides on a ladder chassis with an electronically-controlled low-range terrain mode for the transmission, too.

You’d expect to pay more – even from Korean and Japanese rivals for this much specification. No matter which way you cut it, the D90 is good value.

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.

The D90 was initially offered in Australia with a 2.0-litre turbo petrol four-cylinder, but this 2.0-litre bi-turbo diesel makes much more sense, both for towing and long-distance touring.

It’s a four-cylinder offering a healthy 160kW/480Nm. You’ll note that’s pretty close to Ford’s similar 2.0-litre bi-turbo diesel, which is currently offered in the Everest…

The diesel also gets its own transmission, an eight-speed torque converter automatic with computer-controlled ‘Terrain Selection 4WD’.

This gives the D90 diesel a max towing capacity of 3100kg braked (or 750kg unbraked) with a max payload of 730kg.

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.

The D90 diesel is said to consume 9.1L/100km of diesel on the combined cycle, but ours didn’t score near that with a figure of 12.9L/100km after a week of what I’d consider “combined” testing.

The D90 a big unit, so that number doesn’t seem outrageous, it’s just nowhere near the claim… All D90s have 75-litre fuel tanks.

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 D90 is easier to drive than it looks… to a degree…

It lacks some polish of its more established rivals, which results in a drive experience that isn’t bad, but occasionally frustrating.

The ride somehow manages to be soft and harsh at the same time. It undulates over larger bumps, while transmitting the worst parts of smaller, sharper ones to the cabin. It speaks to a lack of calibration between the suspension and dampers.

That having been said, the D90 masks its ladder chassis underpinnings well, with little of that typical body-on-frame jiggle that some rivals still struggle with.

The drivetrain is good, but a little unruly. As you’d imagine from the figures, there’s more than enough power on tap, but the transmission tends to have a mind of its own.

It will occasionally lurch between gears, pick the wrong gear, and off-the-line will sometimes be delayed before shunting the D90’s bulk forward with a sudden mountain of torque. It doesn’t sound particularly good either, with the diesel surging through the rev range with industrial crudeness.

By the time the D90 has reached cruising speed though, there’s really not much to complain about, with the D90 milling along with plenty of power in reserve for overtaking. The view of the road is commanding, but you really feel the D90’s high centre of gravity in the corners and under heavy braking. The physics of such a large object are undeniable.

I have to say, LDV has done a fantastic job of the D90’s steering, with a quick, light feel that betrays the SUV’s size. It manages to stray on the right side of lightness though, not being so disconnected that you lose a feeling of where the wheels are pointing. No mean feat in something this shape.

Overall then, the D90 isn’t bad to drive and has some genuinely great characteristics, it just also has a litany of small issues that get in the way of it being truly competitive with segment leaders.

The LDV D90 carries a maximum five-star ANCAP safety rating as of 2017, and has a fairly comprehensive active safety suite.

Included on the diesel is auto emergency braking (AEB) with front collision warning, lane-departure warning, blind-spot monitoring, driver-attention alert, traffic-sign recognition, and adaptive cruise control.

Not bad for the price, and nice that there’s nothing optional. Expected items include electronic traction, stability, and brake controls, as well as six airbags.

The curtain airbags do extend to the third row, and there’s the bonus of a reversing camera and a tyre-pressure-monitoring system.

There is a full-size steel spare under the boot floor, and the D90 also gets dual ISOFIX and three top-tether child-seat mounting points.

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.

LDV covers the D90 with a five-year/130,000km warranty, which is not bad… but falls behind sister brand MG, which offers seven years/unlimited kilometres. At the very least it would be nice to have the unlimited kilometre promise.

Roadside assist is included for the duration of that warranty, but there’s no capped price servicing offered through LDV. The brand gave us indicative pricing of $513.74, $667.15, and $652.64 for the first three annual services. An initial six-monthly 5000km checkup is free.

All D90s need to be serviced once every 12 months or 15,000km, whichever occurs first.
