BMW i Series vs Mercedes-Benz Esprinter

What's the difference?

The BMW iX3 is a rarity in the market, a premium-feeling electric model that's not a whole lot dearer than petrol alternatives.

For those happy to trade some of the Tesla Model 3 and Kia EV6 GT's all-paw performance for a luxurious cabin, slick drive and badge cachet, the iX3 M Sport is a very attractive package. Until Audi's Q4 and Q6 e-tron arrive, the iX3 remains basically peerless in this part of the market.

No wonder, then, that BMW is Australia's third most popular electric car brand after Tesla and BYD. The vehicles capture everything the brand promises at a price that looks good on paper and better in the real world.

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.

Now that we've seen the new X3, the current model is already dated. Not that it was a cutting-edge design at launch but there is precious little offensive about this mid-size SUV.

Fussy wheel designs, strange closed in grilles and clashing blue accents aside the iX3 M Sport remains a plenty handsome option as you approach.

Inside the cabin's shapes feel positively conservative next to BMW's latest efforts like the X2 and 7 Series but, in a way, this is no bad thing.

It's also nice that you can tailor this car's appearance to your liking without spending extra, the combination here rocks a nice blue paint with tasteful brown upholstery for a classy look.

You can have Oyster white leather or simple black and the paint colour palette is refined without being restrictive.

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.

The BMW X3 was developed with family buyers in mind and that has paid dividends because it has an extremely practical cabin with lots of thoughtful storage.

Each of the four doors has a bottle holder and generously-sized pocked for extra storage. There are two cup-holders in the centre with a wireless charging pad, secure spot for the key fob and USB port in easy reach. You can slide a roller cover down to hide valuables.

Key driving controls are smartly grouped together around the iX3's unconventional gear selector. Here, you'll find the start/stop button along with hard switches for drive mode selection, stability control and exterior cameras.

Right next door is where the rotary 'iDrive' controller lives with yet more physical shortcut buttons. Including the extra option to easily interact with the multimedia system on the move is a refreshing delight that you don't see in so many touchscreen-heavy EVs. There's also a physical stack for HVAC and seat heating controls.

The 12.3-inch touchscreen is responsive and bright with BMW's slightly older system having a more conventional appearance than the latest software in the iX2. Apple CarPlay and Android Auto are wireless and still work flawlessly.

If there are some negatives, they would be some build-quality niggles. On the whole the materials are high quality and the car is well screwed together but the indicator stalks feel decidedly flimsy compared to BMWs of old and I noticed a rattle from the parcel shelf on the road.

The eight-way power adjust seats with tilt and under-leg extension are classic BMW, being sporty enough to hold you in but with enough padding to stay comfy. Though we will knock this car down for lacking power lumbar adjust.

Those in the back will be plenty comfortable even if they're taller than 180cm with ample head, leg and toe-room. There doesn't appear to be a major compromise to the floor height despite BMW stacking 10 lithium-ion modules beneath.

Vision out is excellent with an expansive glasshouse and full-length sunroof.

Amenities include two USB-C charge points, a third climate zone, fold-out armrest with pop-up cup holders and generous storage in the doors.

Fitting child seats should be pretty simple with doors that open wide, two sets of ISOFIX ports (that you can't lose the covers of) and three prominent top tether anchors in the recline-adjustable backrest.

The boot is large with 510L of space at a minimum that expands to 1560L if you fold the 40/20/40 split backrest flat. There's a sense of solidity in that process, too, with sturdy levers and components.

So sturdy that the retractable luggage cover is quite difficult to remove, especially for shorter owners. Other niceties include a single shopping bag hook, LED lighting and 12-volt socket in the back.

No BMW X3 comes with a spare tyre so that should come as no surprise. The iX3 instead has a tyre repair kit. There is underfloor storage in the iX3, though, which is the perfect place to store both charging cables — Mode 2 and 3 — that are included.

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.

In this case there isn't much under the bonnet except for electric gubbins. The single electric motor – that uses no rare earth materials – resides at the back and generates 210kW/400Nm.

Those outputs are fairly close to a petrol X3 30i, though of course this model is rear-drive only.

Thanks to the rapid response of electric motors, the iX3 M Sport can sprint from 0-100km/h in 6.8 seconds (claimed).

BMW has chosen to give the iX3 a long-travel progressive throttle pedal that makes grunt easy to meter out. However, the regenerative braking could do with a little more refinement.

There are two settings, 'D' — just like letting off the throttle in a combustion car — and 'B' which is quite strong. The blending between regenerative and physical caliper-on-rotor braking is vague, though, which can make low-speed moves a bit jerky.

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.

The iX3 M Sport's WLTP rating is a respectable but not groundbreaking 461km on the combined cycle. The reality is a little bleaker, our test car displaying 316km on its digital instruments at 100 per cent charge.

Going against what you might expect for an electric car, the iX3 was not very efficient in town, we initially saw 24kWh/100km on the read-out which is quite high.

It is better suited to a longer, steady-state run. Our regular 200km country and suburban test loop dropped the consumption to 18kWh/100km for a real-world driving range of 411km.

When it's time to bring the charge levels back up the iX3 will take on AC electricity at 11kW, for flat to full in seven and a half hours.

Public fast-charging caps out at 150kW (DC) though averages to 104kW over a 10-80 per cent session. This should take 21 minutes, says BMW.

We only observed a maximum of 101kW on a DC charger though the pylon did not appear to be performing at full energy with other vehicles having similar issues.

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.

Despite no saucy straight-six, V8 or twin-cam four-cylinder there is an inherent 'BMW-ness' in the iX3 M Sport. The way it steers, accelerates and rides all match the brand's DNA.

It is not a plush SUV, with some firmness to the suspension even in Comfort mode on the adaptive dampers — this may have something to do with BMW's 40PSI front and 45PSI rear tyre pressure recommendations — but without ever being crashy.

Build up a little more speed, beyond 60km/h for example, and the body settles nicely with a solid, assured stance.

There's no evidence of suspension noise and road noise is very well insulated as well, even without the up-spec M Sport Pro's acoustically insulated glass. 

The steering is light in Comfort mode which makes it ideal for urban driving. It also has three turns lock-to-lock which is a lot for a sporty-ish BMW, however that is largely down to the improved steering angle. Without an engine or AWD system, the iX3 has a great turning circle of just 12.1 metres.

Moving things up a notch into Sport adds extra weight to the steering which helps judge the grip on good roads, which is pretty decent from the 245/45R19 Yokohama Advan Sport V107 tyres.

When you approach the limit, the iX3 is very secure but significant mid-corner bumps can unsettle the car, bringing its 2180kg tare weight (a 325kg penalty over the xDrive20i) sharply into focus. Pull it back a touch, though, and the iX3 M Sport is plenty rewarding on a country road.

Mostly, the iX3 is a refreshingly natural electric car out on the road. You could put anyone in the driver's seat and they'd be smooth just like in a combustion car.

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.

The iX3 M Sport is now covered by a five-year/unlimited kilometre warranty in Australia.

Servicing is due on a conditional basis with the multimedia system prompting the owner when to visit a dealer.

BMW offers serviced packages for electric vehicles that last six years/unlimited kilometres, with the iX3's pack costing a reasonable $2325 over that time.

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.
