BMW I3 vs Mercedes-Benz Esprinter

What's the difference?

Yes, it’s pricey for a small hatch, but this little BMW is a city car like no other. The i3s is tailor made for the urban environment, and six years on retains the quirkiness and charisma that stood it apart at launch, and it can still hold its head high among the current EV crop. 

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.

Built around a carbon-fibre reinforced plastic (CFRP) tub, the i3s is ultra-light (for a battery-electric vehicle), super strong, and unlike anything else on the road.

At just over 4.0m long, close to 1.8m wide, and a fraction under 1.6m tall, the i3s is compact, upright, and boxy. A classically polarising design, with some crossing the street to avoid it, and others (like me) loving its unique proportions and stand-out styling.

The nose is tall, short and upright, with the distance from the base of the front windscreen to the front axle (car designers call it the ‘dash-to-axle ratio’) unusually short.

That’s because the electric motor sits in the back of the car driving the rear wheels, with only a small front boot compartment required to house charging cables and other bits and pieces.

Despite the lack of anything of substance behind it, BMW’s signature ‘kidney grille’ is present and accounted for, with swoopy LED headlights (and DRLs) either side. Our test car’s ‘Fluid Black’ finish with ‘i Blue’ highlights dialed up the little car’s charismatic personality.  

One of the i3’s most impressive party tricks is its counter-opening ‘clamshell’ doors, and the engineering trickery used to create a B-pillar free side opening (including the strength of the carbon body structure) means the high window line follows a jagged path from front to back, the rearmost hatch windows shrinking the rear glass area appreciably.

The i3s’s standard 20-inch (dual) five-spoke alloy rims, although slightly wider in this performance model, are alarmingly skinny. But taking the car’s relatively light weight (1245kg) and urban-centric purpose into consideration, the narrow, low-rolling resistance rubber makes sense.

With the roofline and sides of the car tapering distinctly towards the back, the rear view is suitably idiosyncratic, highlighted by flush-fit, vaguely U-shaped LED tail-lights. 

The hatch window is small, and the bumper sits high to marry with the load space floor sitting on top of the motor and transmission.

And when it comes to moving inside, BMW offers a choice of three ‘interior worlds - ‘Loft’, ‘Lodge’, and ‘Suite’ - featuring renewable natural fibres, recycled plastics, naturally tanned leather, and open-pore wood (sourced from 100 per cent Forest Stewardship Council-certified forestry).

But irrespective of where everything comes from, the end result is inviting, comfortable and sub-zero cool. Our car’s ‘Suite’ interior was combined with ‘Oak dark matt’ wood, and ‘Vernasca’ brown leather to stunning effect.

A tunnel-free floor, gently curved dash and digital screens for instruments and media let you know you’re in something different and special. It might be six years old, but the i3 still feels contemporary and distinctive. 

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.

Wide-opening clamshell doors make getting in and out of the i3s a breeze. But bear in mind you have to open the front door to get to the latch for the back one, which can be a pain.

The driver and front passenger enjoy heaps of room, in an open environment, but there’s only a single cupholder in the centre console, so let the coffee cup wars begin.

Aside from that there are seriously big bins in the front doors, a modest glove box, and a handy elasticised pocket near the floor at the base of the bulkhead.  

Outlets for 12-volt and USB are provided, and there’s a small oddments tray at the rear of the centre console.

Slip around to the rear and you’re in anything but limousine territory. Sitting behind the driver’s seat set for my 183cm height, head and legroom are modest but do-able. And remember it’s two seats only back there.

In terms of storage, there are two cupholders between the seats but no storage pockets or bottle holders in the doors. You won’t find adjustable ventilation outlets either, but that’s not a huge factor in car of this stature.

The boot’s volume is quoted at 260 litres with the 50/50 split-fold rear seatback upright, which is enough to easily swallow the largest 124-litre suitcase in the CarsGuide three-piece set. The smaller 95- and 36-litre cases will sit side-by-side without a problem.

Fold the rear seat down and you have 1100 litres of space at your disposal, with tie-down anchors, an elasticised pocket and 12-volt power provided.

Don’t bother looking for a spare of any description, a repair/inflator kit is your only option. And not surprisingly, the i3 is a no-tow zone. 

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.

The i3s is powered by BMW’s ‘eDrive’ hybrid synchronous electric motor, producing 135kW at 7000rpm, and 270Nm from 0-4500rpm. Yep, that’s right, maximum torque is delivered the instant you depress the right-hand pedal, and we’ll get to what that brings to the driving experience a little later.

The unit incorporates a charging and generator function for braking energy recuperation, the latter delivering up to 50kW.

Drive goes to the rear wheels via a single-speed (fixed-ratio) automatic transmission.

The battery powering the whole show is a 352-volt/120 amp-hour (Ah) Lithium-ion unit with a (gross) energy rating of 42.2kWh.

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.

When it comes to an electric car’s energy use and projected range, there are two main things to consider - the motor’s power consumption and the battery’s capacity.

And according to BMW, the i3s’s power consumption for the combined (urban/extra-urban) cycle is 14.6–14.0kWh/100km.

Over a week, and roughly 250km of urban driving (with some brief freeway runs thrown in) we saw 19.3kWh/100km staring back at us from the on-board computer.

When BMW launched the i3 in Australia in 2014, the pure EV version came with a 60Ah battery pack delivering a claimed 130 kilometre range (a range extender model featuring the addition of a two-cylinder petrol motorcycle engine was also offered). 

In 2016 a 94Ah version arrived to boost range up to 183km, and the i3s launched in 2018, with its 120Ah battery pushing range out to BMW’s current, real-world estimate of 260km.

Then, there’s charging time, which is like asking how long is an electric piece of string.

According to BMW, for a 0–80 per cent charge from a (50 kW DC) fast-charging station, you’re looking at 45min.

From a (11kW/16A/380V) high-output home/office wall unit, that pushes out to 3.10h, and using a (3.7kW/16A/240V) low-output home/office unit stretches the wait time to 9.40h.

BMW offers the ‘WallBox plus’ charging suite as a dealer accessory priced from $1990 (not including GST or install costs).

Plug into a domestic (2.4kW/10A/240V) socket, and you’re staring down the barrel of 15.00h. But at least you can use low-cost, off-peak energy overnight, right? Nah, I don’t buy that line either.

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.

It might not look like a conventional sports car, but the BMW i3s certainly accelerates like one, with a claimed 0-100km/h time of 6.9sec. The i3s is a smile-inducing hoot to drive.

Every one of this little hatch’s 270 newton metres of torque is available from the minute you hit the accelerator pedal, and remain in service until 4500rpm, at which point torque delivery drops off a cliff.

But peak power steps in at exactly 7000rpm, so if you’re determined to make that overtaking move you won’t be left in the lurch. In fact, BMW says it only takes the i3s 4.3 seconds to surge from 80km/h to 120km/h.

However, the i3’s forte is 100 per cent the city, rather than the open road. Its ‘point and squirt’ ability making it the perfect partner for the cut and thrust of the urban jungle.

The i3s features an upgraded ‘Sports Suspension’ incorporating firmer dampers, re-tuned springs and revised anti-roll bars. It’s also lowered 10mm, the track is widened (+21mm front / +2.0mm rear) and the wheels go plus one inch to 20-inch alloys.

The standard i3 (no longer offered in Australia) rolls on 19-inch rims shod with 155/70 rubber all around. And while the i3s’s 175/55 front and 190/50 rear tyres are still exceptionally narrow, from the side the low-profile Bridgestone Ecopias look like fan belts wrapped around pulleys rather than tyres around wheels..

No surprise then that ride comfort isn’t exactly cushy, and in signing on for the i3s experience you’ll need to be ready for more than occasional bumps and thumps.

But the pay-off is super-sharp dynamics, Suspension is by alloy struts at the front, and a five-link alloy set-up at the rear..The steering responds to inputs quickly yet smoothly, and with 48/52 front to rear weight distribution, the car always feels balanced, eager, and taut.

And if you really want to dial things up the ‘driving experience control’ allows a switch to Sport mode for a further tweak of the suspension, steering, and traction control set-ups.

A tight 10.3m turning circle makes for easy parking and stress-free U-turns. But if things get too tight, rapid three-point turns are assisted by the gear shift controller bring mounted on a chunky stalk on the right-hand side of the steering column. Too easy.   

Braking is by vented discs front and rear, but they’re tiny. That’s because the ‘Brake Energy Regeneration’ system does most of the work. 

Effectively turning the motor into a generator, the system not only slows the car dramatically but feeds energy to the battery in the process. It takes a while to get used to the sensation, but soon becomes a fun, and surprisingly easy game to use the brake pedal as little as possible… often not at all, for long periods.

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 offers a three year/unlimited km warranty, which is off the pace given the majority of mainstream brands have stepped up to five-year cover, with some at seven. And the pressure is on with Mercedes-Benz recently announcing its shift to five years/unlimited km.

That said, the BMW's body is warranted against rust (perforation) for 12 years/unlimited km, and roadside assistance is provided free-of-charge for three years/unlimited km.

Maintenance is 'condition based' with sensors and on-board algorithms (mileage, time since last service, driving style) determining whether an annual vehicle inspection is required.

The 'BMW Service Inclusive' package, offering a single, one-off advance payment to cover selected service and maintenance costs, is available in two levels - 'Basic' ($850) or 'Plus' (dealer quote)

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.
