BMW 6 Series vs Mercedes-Benz Esprinter

What's the difference?

This isn't a car for everyone's tastes, but if you fit in to the buyer group that just doesn't really know what they want in a luxury car, it could be the perfect fit for your family. The 6 Series GT is a practical large prestige car, albeit one that will likely find very few buyers.

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.

There is no denying the 6 Series GT looks better than the old 5 Series GT. It isn't as frumpy, it looks more sporty, and to me it appears to have grown into its identity with more conviction than its predecessor.

That said, I don't necessarily like the look very much - it's a bit like a BMW X6 that has been rounded off a little and lowered down substantially. But I can appreciate some of the finer design aesthetics that it offers up: the frameless windows are a nice touch, and the swooping roofline looks smoother than a duck's back.

Other things like the active grille shutters and the air breathers ahead of the front doors are nice functional touches, and to my eye it lives up to BMW's hope of it looking "smooth but muscular". You can get the 630i with either the M Sport package, like you see here, or the more sedate Luxury Line, which is, well, more luxurious looking.

The M Sport styling and equipment package you see in the images here - with M aero kit and 19-inch wheels (ours had been upgraded to optional 20s) - help out with the athletic look of this very big vehicle.

It's huge in fact. The length of the 630i is 5091mm long, it measures 1902mm wide and sits at 1538mm tall, with a lengthy 3070mm wheelbase.

All that equates to a lot of room in the cabin, and what a sumptuous and delightful place it is to be - leather, wood and plush finishes abound.

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.

Now, I said before that this is a bit like an X6, but it has heaps better interior space than that SUV.

As soon as you slide into the driver's seat, you feel like your inside a large car. The cabin space is plentiful, and there's an abundance of storage on offer, too: there's a split-lid armrest between the seats, a pair of cupholders, a phone storage nook with wireless charging, and big door pockets with bottle holsters.

In the back you have access to door pockets, a flip-down armrest with cupholders (that middle part of the seat can fold down completely to allow storage of longer items), and there's excellent room on offer. How many seats in the BMW 6 Series GT? Five - like, five full-size seats.

Because the roofline doesn't rake as sharply as a four-door 'coupe', headroom is excellent for adults (even of the 183cm variety, like myself), and legroom and toe room are equally very good. This is bigger in the back than a 5 Series, but maybe not as plush as a 7 Series… so I guess it makes sense numerically for its nomenclature.

Of course you get climate control in the front (and in the rear if you option it), and the materials are excellent. The media screen is tablet-style, proudly displaying 10.25 inches of high-def real estate that is both touch-capacitive and controllable by way of the central rotary controller with touchpad. And get this - you can even use gestures to control certain elements like volume, swiping and changing tracks… but you have to option that.

The fully digital instrument display is bordered by a set of incomplete dial rings, which is just odd. BMW, back yourself - your buyers can handle just having a digital screen in front of them, particularly when it's as good as this one.

This grandiose hatchback's boot is commodious - with the back seats in place it has a huge 610 litres of cargo capacity, which extends to 1800L with the 40/20/40 seats folded down using the quick release levers in the boot area.

There is no spare wheel (the BMW range is fitted with run-flat tyres) but it does have a secondary hidden storage area under the boot floor for hiding items or stowing wet gear, bathers/swimmers or muddy clothes.

For context, the X6 has 580L seats up, 1525L seats down.

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 local eSprinter range, which does not include a cab-chassis variant, offers a choice of van-based models comprising the MWB (Medium Wheelbase) with 81kWh motor for a list price of $104,313 and LWB (Long Wheelbase) with 113kWh motor for $121,041. This six-figure pricing is in the same ballpark as full-electric large van equivalents from Ford (E-Transit) and LDV (eDeliver 9).

Our test vehicle, finished in standard 'Arctic White', is the smaller MWB/81kWh model equipped with the optional High Roof (option code DO3) which adds almost half a metre (489mm) to its external height and $2392 (ex GST) to its price.

Its work-focused standard equipment includes 16-inch steel wheels with 225/75 R16 tyres and a full-size spare, DRLs and side marker lights, sealed cabin bulkhead with central window, electric-adjustable truck-style exterior mirrors, heated driver’s seat and exterior mirror, prestige leather-rimmed steering wheel with multiple remote control functions, colour 5.5-inch driver’s information display, reversing camera, front/rear parking sensors and tyre pressure monitoring to name a few.

The cabin also has an electronic parking brake, electric air-conditioning and heating plus multiple USB ports and 12V sockets. The latest 'MBUX' multimedia system features a large 10.25-inch touchscreen as central command offering voice activation, digital radio, wireless Apple/Android connectivity and more.

Under the bonnet of the 630i is a 2.0-litre four-cylinder turbocharged petrol engine, which produces 190kW of power (at 6500rpm) and 400Nm of torque (from 1550-4400rpm). It uses an eight-speed automatic transmission, and is rear-wheel drive.

That may not seem a lot considering the size of this machine, but consider that some of the steamiest four-cylinder hot hatches have nearly the same outputs, and you realise this engine offers up a far-from slouched approach to propulsion.

The 640i xDrive has a 3.0-litre six-cylinder turbocharged engine with 250kW of power and 450Nm of torque. It gets the same eight-speed auto, but as the xDrive naming indicates, it's all-wheel drive.

But this is the one you'd prefer if you want to hit highway speed in a hurry - the 0-100km/h claim is 5.3 seconds, where the 630i takes a full second longer (6.3sec) according to the company.

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.

BMW claims fuel use of 7.0 litres per 100 kilometres, and you'll need to use 95RON premium unleaded when you fill up.

On my trip with the car, I saw about 9.0L/100km across mostly high-speed driving - some freeway, some highway, some country back road touring, and quite a bit of corners and city stuff thrown in as well. I think that's pretty respectable.

What wasn't so great was the lack of premium fuel in some of the 'away from civilisation' places on my route home. Keep that in mind if planning your own GT long-distance cruise.

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.

I'll put this out there - if you like to drive, there are BMW models for less than this one that will put a much bigger smile on your face. Like, a 440i Gran Coupe, or even just a 330i sedan…

But if you're in BMW's target market - that being older executive buyers who want space and luxury as a priority over thrills at the wheel, you could do a lot worse.

That's because the 6 Series GT lopes along the highway without fuss - the engine easily coping with the demands of overtaking moves, the adjustable drive modes allowing a light steering and wafting suspension feel to wile away the kilometres.

There are 'Comfort' and 'Comfort Plus' modes, but the latter is a bit too spongy and can be boaty feeling. The Comfort setting is made for the highway.

It is actually pretty agile for its dimensions.

If you decide to deviate from the straight sections, you'll be able to explore a little bit of dynamic range, especially when you dial up the 'Sport' mode, which changes the damper settings, steering weight, throttle and transmission response, and even the digital dials in front of the driver to a more aggressive look.

Our car had the 'Integral Active Steering' setting, which is a variable ratio steering system that includes rear steering - that essentially helps make is more turnable in corners at highway speed, and easier to park at lower speeds. It's difficult to say whether the assistance is excellent or not short of driving a car without the tech, but to this tester it was hard to hide the size and weight (1835kg kerb weight) of the vehicle.

That isn't to say it's clumsy or lumbering - it is actually pretty agile for its dimensions, though it makes a lot more sense on long drives and coastal cruises than it does in the narrow and twisty alpine roads of the Snowy Mountains Highway that I tested it on.

There's good grip from the tyres, and strong response from the powertrain - but if it were my money, and I had to have a 6 Series for whatever reason, I'd be looking towards the 640i model, which has a thumping six-cylinder with 250kW/450Nm - certainly an engine that would be more at home in this car. Plus that model comes with AWD.

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.

There’s no ANCAP star rating for commercial vans above 3.5-tonne GVM but the eSprinter did score the maximum Platinum grade in ANCAP’s Commercial Van Safety Comparison in 2024.

It comes standard with six airbags, active distance assist (can automatically brake and accelerate in traffic), lane-keeping, multiple blind-spot monitoring, rear cross-traffic alert, tyre pressure monitoring, reversing camera, front/rear parking sensors, crosswind assist and many more.

BMW runs a condition-based servicing plan, which means the car will tell you when it needs servicing. But you can rest assured it won't (theoretically) cost you much, with the brand's 'Service Inclusive' pack. It covers you for basic maintenance as and when required for five years/80,000km. According to BMW, that includes "annual vehicle checks, oil changes, all filters, spark plugs and labour costs for the duration of the package".

BMW offers a three-year/unlimited kilometre warranty plan, and you get the same cover for roadside assistance.

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.
