Mercedes-Benz Esprinter vs Subaru Liberty

What's the difference?

With the convenience of back-to-base charging the eSprinter would be well suited to last-mile logistics or other urban delivery roles, as its driving range is ample for many of these urban tasks with the added benefit of zero tailpipe emissions. However, at more than $100K it is a big spend (like its full-electric rivals) so only a thorough cost-benefit analysis can decide if it’s the right choice for your business.

The Liberty has a lot going for it - a great reputation for reliability, it isn't terribly priced (although servicing is a little steep) and has that signature all-wheel drive. While I've complained about the ride and handling, apart from STi and RS-badged versions, that has never been the Liberty's strong suit.

While it might be a shrinking part of the market - and Subaru is a founding architect of the modern SUV cult - Subaru and its competitors still care. The Liberty, like Forester and Outback, remains a stand-out in the sector with a boxer 2.5 and all-wheel drive. Sometimes that kind of individuality is enough.

This is a substantial vehicle riding on a 3665mm wheelbase and spanning almost 6.0 metres in length (5932mm) and more than 2.0 metres in width (2020mm without mirrors), yet it has a tight kerb-to-kerb turning circle of only 12.4 metres.

And with the optional High Roof as fitted to our example it stands almost 3.0 metres tall (2867mm), so drivers need to be conscious of this extra dimension when accessing underground loading zones, driving under height-restricted bridges etc.

Its rear-wheel drive unitary chassis features simple and rugged McPherson strut front suspension paired with a De Dion-style rigid beam/leaf spring rear axle, along with four-wheel disc brakes and electrically assisted power steering.

There’s prominent use of unpainted dark grey plastic in external areas where bumps, scrapes and wear are usually inflicted, including the grille, front bumper, hubcaps, doorhandles, door mirror shells, side bump-strips and rear bumper.

The cabin design is spacious, neat and functional, with unique instrumentation which replaces the traditional tachometer with a gauge that monitors driving efficiency. There’s also a digital info screen that displays average energy consumption, battery charge, estimated driving range, gear selection and more.

Here's a thing - this week I regularly parked my car in the same street as a fourth-generation Liberty. I kept heading for it at the end of each day because that design feels a lot more contemporary than the current car.

I came to my senses every time before trying to get in, but it does tell you that today's machine is a little on the dowdy side. While not the horror of the lines-everywhere-slab-sided fifth-generation model, I don't think the styling has escaped unscathed from the mess of the car it replaced.

This one won't scare small children or start pub arguments, though, and is a more cohesive, gracefully-ageing design. The LED daytime running lights and, in the case of the Premium, LED headlights, give it a modern feel and its less imposing headlight design is rather more pleasing. 

Little has happened as part of the refresh, with just the requisite number of visual tweaks. The front and rear bumpers (now with subtle diffuser) are a bit sharper and new wing mirrors and grille all add a little extra - but not much - to the 2014 original.

Inside is pretty much the same as before. The touchscreen has a flat, glare-prone screen but the rest of the cabin is well thought through, if entirely conventional. The flashy alloy pedals are a fun touch, though, and the materials choices are solid if uninspiring.

With its hefty 2727kg kerb weight (largely due to the battery) and 4250kg GVM, the eSprinter has a sizeable 1523kg payload rating. It’s also rated to tow up to 2000kg of braked trailer but with its 5000kg GCM (or how much it can carry and tow at the same time) that big payload must shrink to only 273kg to legally tow its maximum trailer weight.

That’s only enough payload capacity to cater for the weight of a two-man crew and little more so it’s important to be aware of these numbers if you’re planning to tow this heavy (although we suspect few if any owners would do so).

The cargo bay with the High Roof option is enormous, with 2009mm from floor to roof allowing even tall people to stand without stooping. Its load volume is a cavernous 10.5 cubic metres.

The load floor, which is protected by a hard non-slip surface, is 3375mm long and 1732mm wide with 1350mm between the rear-wheel housings. This allow up to two Aussie pallets or up to four Euro pallets to be carried, secured using a choice of 10 load anchorage points which fold flush with the floor when not in use.

Cargo bay access is through a sliding kerbside door with a big 1260mm-wide opening and a pair of rear barn doors which can open to a full 270 degrees on each side to optimise access to forklifts and loading docks.

The walls and sliding door are neatly lined to roof height and large handles inside both door openings assist access. There’s also bright LED lighting plus handy storage pockets in each rear door.

Its spacious cabin provides a comfortable and efficient workspace. The fabric-trimmed bucket seats offer generous head and legroom for driver and passenger and the ample open floor space between them features a sturdy cradle in which to carry the charging cable (see image).

There’s also ample storage including a large bottle-holder and multiple bins in each door plus a full-width overhead shelf with a key-lockable security box and a central glasses holder.

The top of the dash has two cupholders on each side (so, four in total) plus a large compartment with clamshell lid in the centre equipped with a 12V socket and three USB-C ports. There’s another shelf in the lower dash on the passenger side, a quartet of cupholders in the centre console and yet another compartment hidden beneath the passenger seat.

The Liberty has a terrifically spacious interior. Rear seat passengers have a huge amount of legroom, with a ton of room behind my driving position (I'm 178cm) for long-legged teenagers. There's also plenty of legroom and even air vents.

The cabin has four cupholders in total and four USB ports, two up front and two in the back.

If you found a way to fill the boot with water you'd get 493 litres aboard and you can drop the 60/40 split fold seats for yet more space.

The Liberty's sixth-generation has arrived at middle age and Subaru took the opportunity to tweak the specification as well as the looks. Second in the three car range is the 2.5i Premium, which sits between the 2.5i entry-level and the 3.6R, and carries a $36,640 price tag.

Standard on the Premium are 18-inch alloys, a six speaker stereo with Bluetooth and USB, dual-zone climate control, keyless entry and start, active cruise control, powered and heated front seats, sat nav, auto high beam, active LED headlights, a very impressive safety package, partial leather seats, leather steering wheel, power everything, sunroof and a full-size spare.

The 7.0-inch touchscreen now not only features sat nav and a half-decent media system but also has Apple CarPlay and Android Auto, which is still a rarity in this class. Also a rarity is the standard all-wheel drive system (good) and the CVT auto (maybe not so good).

The eSprinter is powered by a single electric motor producing 150kW of power and 400Nm of torque. It’s mounted under the rear floor where it drives the rear wheels through a single-speed transmission.

This compact motor-trans unit shares underfloor space with an 81kWh lithium-ion battery that provides the motor’s energy. This battery occupies most of the underfloor between the front and rear axles and features a slimline design to optimise ground clearance.

Drivers have a choice of three drive modes comprising 'Comfort', 'Economic' and 'Max Range', plus different levels of energy recuperation using steering wheel-mounted paddles that adjust the intensity of regenerative braking.

The electric motor also features a ‘boost’ function which temporarily increases power output when fast acceleration or overtaking is required. The eSprinter’s maximum speed is capped at 120km/h.

Like the overall specification, the drivetrain has received some attention. While power outputs are the same as before - 129kW/235Nm - the CVT auto with which Subaru's 2.5-litre boxer engine is paired is slightly improved. Even in the quiet of the cabin you hear that 'flat' four-cylinder's trademark gravelly growl.

Being a Subaru, all four wheels receive their share of power. The Liberty's published towing capacity is 1500kg for braked trailers and 750kg unbraked. If you need a bit more, the six-cylinder 3.6R can handle another 300kg.

Mercedes-Benz’s official driving range for the 81kWh eSprinter, based on combined WLTP testing, is up to 264km. When we collected the vehicle for our test, the battery was fully charged but the estimated driving range displayed was only 234km, or 30km less than the official figure.

The eSprinter’s towering height also stopped us accessing local charging infrastructure (located inside multi-storey car parks) so our test was conducted using the initial single charge. This included a mix of suburban and city driving best suited to electric van use and covered a total distance of 190km.

At the completion of our test, the dash display claimed average energy consumption of 29kWh/100km, with 25 per cent battery charge remaining and 63km of estimated range. So, based on these figures, the official WLTP range of up to 264km is credible.

The eSprinter comes standard with a Mode 3/Type 2 charging cable and the charging port is in the centre of the grille behind a spring-loaded flap displaying a three-pointed star badge.

Mercedes-Benz claims 11kW AC charging of the 81kWh battery from 10-80 per cent takes around eight hours while 115kW DC fast charging reduces that to around 32 minutes.

Subaru says the combined cycle fuel figure is 7.3L/100km and I got 9.3L/100km with a mix of suburban and 80km/h running.

The fuel tank is a generous 61 litres.

There are large handles on the front door window frame and overhead shelf to assist climbing aboard, where you’ll find a comfortable and commanding driving position.

This is thanks to supportive seating (albeit with no lumbar adjustment), ample steering wheel height/reach positioning and a spacious footwell, combined with a clear rear view through the bulkhead window and along the sides thanks to large truck-style mirrors.

The leather-rimmed steering wheel feels nice in your hands, all major controls are easy to see and operate and the electric air-conditioning and heating systems are effective.

It’s a pleasant vehicle to drive as the most noise you hear is the tyres, given the near silence of the rear-mounted motor and drivetrain. The underfloor location of the battery also creates a low centre of gravity, which optimises handling with minimal body lean when cornering.

Unladen ride quality is excellent, enhanced by the weight of the battery which helps the suspension iron out bumps. And the electric motor’s 400Nm of torque provides energetic performance, with acceleration delivered in a smooth liquid-like surge.

Selecting the strongest regenerative braking not only optimises energy harvesting for the battery but also creates enough retardation to ensure mostly single-pedal driving (accelerator only) as the brake pedal is rarely required. This mode is also handy on steep descents.

To test its payload rating we forklifted 975kg into the cargo bay, which combined with our two-man crew equalled a total payload of 1155kg that was still comfortably below its legal limit.

The rear leaf springs compressed less than 30mm under this loading, leaving ample bump-stop clearance to ensure no bottoming out on our test route. The e-motor’s response was more subdued as you’d expect but it still hauled this payload with apparent ease.

Overall, the driving experience was hard to fault, apart from the vertical pillar between the fixed and sliding glass in the driver’s door blocking the outer third of the exterior mirror’s view, at least with the driver’s seat positioned far enough rearwards to suit my 186cm frame.

We also noted, when travelling at highway speeds on a windy day, that our test vehicle was prone to being moved within its lane by strong crosswinds, even though ‘Crosswind Assist’ is included in the active safety menu.

We suspect the High Roof option was responsible for this given the larger bodysides it creates and is something to be mindful of when driving in high wind conditions.

Subaru says the Liberty has undergone some changes to improve the driving experience. To my backside, that hasn't worked out perhaps as intended. At least I hope so, because the results aren't terrific. The ride is particularly odd - in the corners there is noticeable body roll but it bangs and crashes over bumps, the rear passengers suffering worse than those up front.

In the cruise it's perfectly reasonable and the car is very quiet, indeed it's pleasant at speed. At lower speeds, there is a lack of feel contributing to the feeling that the wheel lacks accuracy. Nothing dramatic, but I felt like I was constantly correcting it the way Parisians correct my high school Francais.

Cheeringly, what I expected to be my least favourite part of the car was quite good. I am monotonously on record dissing CVTs because generally, they're pretty terrible. After six months with one in the Forester, I was never comfortable with it. 

Here in the Liberty, it seems better integrated with the engine, with much better control of the trademark flaring and it's only when you really get the accelerator up against the firewall that you're reminded you're driving a rubber band. When you switch from I (Intelligent) to S (Sport) mode, it also responds accordingly, but there's never going to be fireworks.

The brake pedal is a bit on the mushy side, too, but its stopping ability was never in doubt. I guess the final verdict is that some parts of the experience are dreamily isolating while others are not as good as you might expect.

The Liberty ships with seven airbags (including driver's knee), lane-keep assist, adaptive cruise with brake light recognition, ABS, traction and stability controls, reversing camera, forward and side view cameras, reverse cross traffic alert and blind spot monitoring. 

Bafflingly, there are no parking sensors at all on any Liberty. I know that sounds churlish, but I don't park watching a camera and like the beepers so I can watch somewhere else. Give me a beeper and a dipping left-hand mirror any day.

On top of all that, the 'EyeSight' system is also fitted. EyeSight is a pair of cameras pointing forward that not only powers the lane keep assist, but lets you know if you're drifting or approaching an obstacle too quickly. It also detects pedestrians and in this latest iteration will work up to 50km/h rather than 30km/h as before.

As you might expect, the Liberty scored five ANCAP stars in December 2014.

Then eSprinter comes standard with a five-year/250,000km warranty including 24/7 roadside assist for the same duration. There’s also a separate eight years/160,000km warranty covering the lithium-ion battery.

Scheduled servicing is every 12 months/40,000km whichever occurs first. Capped pricing applies to the first five scheduled services totalling $1920, or an average of $384 per service. Pre-paid service packages offer additional savings.

At three years/unlimited kilometres, the Subaru warranty is now starting to look a bit thin compared to, say, Korean rivals. Over the three years of the capped-price servicing you'll wear $2281.66 for up to 75,000km of servicing. 

Subaru expects to see you every six months or 12,500km, so that averages out to $380 per service.

Hyundai's Sonata will cost you just $795 over the same period (for fewer visits), a Mazda6 will only hit you for between $308 and $336 per service, and a Camry will cost just over half what Subaru charges every year.
