BYD Sealion 6 vs Mercedes-Benz Esprinter

What's the difference?

So, should Toyota, Tesla, Hyundai and others be worried about the arrival of the Sealion 6 and BYD’s new DMi powertrains? Yes, but not because it represents any major breakthrough in technology or dynamic prowess. 

Instead, the strength of the Sealion 6 is how average it is. It may not be the obvious class-leader in any particular area, but it does a good job in almost every measurable aspect and doesn’t possess any major flaws.

Yes, there are still questions about the long-term dependability of BYDs but that’s a risk any new owner will need to accept. But the very sharp pricing should tempt plenty of buyers to take that chance and continue BYD’s steady upwards trajectory in the Australian market.

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.

This is one area where BYD has a mixed record. Not to be unkind or create an international incident, but the Chinese car industry has a history of not being totally original with all of its automotive designs.

However, things are improving and the Sealion 6 is a good example of the Chinese industry learning to develop its own style. While there are some subtle hints from European models, overall it’s a smart-looking mid-size SUV with some character to it - rather than being a bland imitation of something else.

One area where the Sealion is a cut above its competition is its size, being longer than and wider than the RAV4, Mitsubishi Outlander and Nissan X-Trail.

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.

That external size translates to a roomy cabin, which also has some flair to the design but thankfully a bit more restrained than the smaller Atto 3 - which is a bit over-the-top in this reviewer’s opinion. 

The element that sticks out immediately is the large central touchscreen which, like other models in the range, can rotate either vertical or horizontal, depending on your preference.

I don’t understand the point of this, because when rotated vertically it impacts your forward vision and can interfere with the air conditioning vents; and I can’t even see it with my polarised sunglasses.

It simply makes more sense horizontally, but I guess all carmakers are looking for catchy gimmicks these days. But while it may seem like a cool party trick it remains somewhat confusing to me, like one more thing to go wrong. But maybe I’m just getting old and grumpy.

What I do like and think is a great idea is double smartphone charging pads in the centre console. And overall the design of the cabin feels well thought out and has plenty of useful storage areas.

The seats are fine, a little flat and the fixed headrests are irritating, but overall they’re soft and supportive enough.

The key in the second row seating is the amount of space, with the extra length of the Sealion 6 compared to its rivals showing up with more knee room in the back for families with growing teenagers or those who need to carry their adult friends.

There’s also a pair of USB ports in the back too, so everyone can keep their electronics charged.

The boot is a good size, measuring 425 litres on paper, and has a nice long and wide floor. But some of that space is thanks to the lack of a spare - so that counts against it in my book.

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.

While BYD has made its name in Australia as an all-electric brand it has always referred to itself as a 'new energy' company, and the Sealion 6 (and upcoming Shark ute) are why.

That’s because these feature BYD’s new 'Dual-Mode Intelligence' (DMi) powetrain - a hybrid system to you and me.

As mentioned above, the biggest difference between the Dynamic and Premium models is the powertrain, with two reasonably different systems.

The Dynamic is powered by a 78kW/135Nm 1.5-litre four-cylinder petrol engine, paired with a 145kW/300Nm electric motor - making for a combined system output of 160kW/300Nm. Notably, this powertrain only drives the front wheels.

In contrast, the Premium has an all-wheel drive set-up, combining a turbocharged version of the petrol engine (good for 96kW/220Nm) with a pair of electric motors, one on the front axle and one on the rear to produce a combined output of 238kW and 550Nm.

Both models get the same 18.3kWh ‘Blade’ battery, which is BYD’s proprietary technology underpinning all of its models and is attracting attention from other brands.

For reference, the Outlander PHEV has a 20kWh battery, Nissan’s X-Trail e-Power has a 2.1kWh battery, while the more conventional RAV4 Hybrid has just a 6.5Ah battery.

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.

There are multiple modes to drive it in, including electric only, with the Dynamic able to go up to 92km on a single charge, while the Premium manages a claimed 81km.

However, it's important to note these are the NEDC standards and not the more real-world like WLTP,  so you may not achieve those in practice.

The claimed fuel consumption is an impressive 1.1L/100km for the Dynamic and 1.4L/100km for the Premium although again achieving those in the real world will take some effort.

With a 60-litre fuel tank BYD claims the Dynamic has a driving range of just over 1000km, while the Premium can manage around 960km.

It's also worth noting the Sealion 6 comes equipped with vehicle-to-load charging which means you can draw power from the batteries to run small electronic devices if you need to.

It’s a bonus feature that may or may not be of use, but is one of those things that may come in handy one day to get you through a camping trip or a BBQ at the park.

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.

We drove the Sealion 6 Dynamic and despite having the less powerful powertrain it feels good on the road. The DMi system offers good performance, with quiet acceleration off the mark and a good integration between the petrol engine and electric motors. We haven’t driven the Premium yet, so we can’t make any comment on how different it feels.

It’s hard to make a definitive call on the Sealion PHEV powertrain because, like every plug-in hybrid, its greatest strength relies on how the owner operates it.

If you don’t charge the battery every day or so, you’ll just end up lugging around a battery and electric motor for little benefit. However, if you do keep the battery topped up, you can do most of your urban commuting without needing to turn the petrol engine on, which should result in some very low fuel consumption figures.

The company clearly knows this, which is why BYD Australia is offering a complimentary home charger to the first 3000 customers who order a Sealion 6.

Not only will that encourage sales but it will also help owners become evangelists for PHEVs in the future, because they’ll have the best possible experience.

So, a large part of its strength or weakness rests on the owner’s behaviour and that’s something we can’t assess.

As for the rest of the driving experience, the ride comfort is fine. It can’t match the class-leaders for compliance or dynamics, but the Sealion feels pleasant to drive around the urban environment and on the freeway at speed.

Biggest criticism is the steering is very, very light. While that makes parking easier, it feels so light you get very little feedback from the front wheels so it can feel vague at times.

Overall the driving experience is best described as fine. It doesn’t have any major vices but neither does it set any new benchmarks. 

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.

BYD is a small company but has partnered with mycar service centres to make maintaining your Sealion 6 easier. The Sealion is covered by BYD's six-year/150,000km warranty as well as its 10-year capped price servicing plan.

Service intervals are every 12 months/20,000km and prices range from $265 up to $1184 for the major eight year/160,000km tune up. Over the first five years, in keeping with most of its rivals, you’ll be paying $1648.

As I’ve written in previous BYD reviews, the biggest question mark hanging over the brand is arguably its long-term prospects. Quite simply, the brand is still too new to know how well it will perform on the used car market.

We also can’t tell you how it will hold up from a reliability point-of-view. We’re not suggesting there’s any doubt over its quality, but each car brand must prove itself reliable and dependable over time, and BYD hasn’t had that time yet.

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.
