BYD Seal vs Peugeot E-Partner

What's the difference?

Those big auto executives have good reason to be worried, because the Seal is yet another impressive offering from China’s most formidable EV player.

It’s not perfect. In some ways it’s trying too hard to be a luxury car, and I think the software in particular could use a little work, but the Seal just does so much right I think it will be hard to be disappointed with one, particularly given its keen entry price.

In fact, if we had to pick one from the range, it would probably be this mid-spec Premium. The range and power on offer are stellar, and all for less money than an entry-level Model 3 or Polestar 2.

It’s a lot of money for a small commercial vehicle that’s well into its current model cycle in Europe, falls short on benchmark safety and requires convenient charging infrastructure to minimise inconvenience for owners. However, its emissions-free drivetrain is quiet and competent under load, with a range that should comfortably cater for the daily urban use small van operators typically require. Whether those positives outweigh the negatives, only a potential buyer can decide.

The Seal looks great. It’s about as modern a take on the traditional three-box sedan as you can get. It’s low-slung with curvy lines and a sporty overall feel.

The design touches, like the headlight and DRL surrounds, side skirts, and wheels are maximalist compared to the minimalist vibes of the Model 3 and the Polestar 2. But I don’t necessarily think that's a bad thing as it offers buyers a genuine alternative.

I also like the way the brand has executed the LED lights and particularly the tail-light fittings. There’s also an admirable restraint when it comes to badging compared to a lot of this car’s Chinese rivals. It doesn’t give off the vibe of a cut-price product at all.

Inside there are elements which are appealing, and some things which fall short. First up, I do think the Seal wears its influences throughout the industry on its sleeve a bit.

The digital dash cluster theme, for example, seems to (poorly) emulate the Mercedes-Benz software, the little plastic crystal shifter piece on the inside seems to have been overtly influenced by a similar (actual crystal) piece available in Volvos, while the centre screen and dual wireless phone chargers are pretty obviously BYD’s take on the similar bits available in the Model 3.

Maybe in this sense, it’s trying a little too hard to be a luxury car and a tech-heavy electric vehicle, with items which aren’t quite up to the same quality (particularly the software). But then, it all works well enough, and can you complain at the price?

One thing I think BYD gets right though is the level of comfort on offer in the cabin and the clever little styling bits which remind you of its namesake.

The door handle pieces and integrated speaker bits are shaped like a Seal flipper. As are the dash-mounted air vents, and if you look closely even the plastic garnish on the steering wheel looks a bit like a top-down cross section of the animal.

I like it because its subtle rather than in-your-face as some of the Atto 3's design elements are.

The quality is also up to muster, big time. There wasn’t a creak, groan, or rattle from this car’s interior in my entire time with it, including on some of Sydney's worst roads. And the seats, which are designed like absolute thrones, are clad in lovely soft leather. You sink into them. Even the two-tone Alcantara finish through the doors and centre console is thoughtfully placed.

The single electric motor is positioned at the front where it drives the front wheels. The 50kWh lithium-ion battery that provides its energy is located beneath the cargo bay’s load floor to ensure that the total load volume, floor loading heights, etc, are identical to the petrol version.

The same applies to its compact 2975mm wheelbase, 4753mm length, 1921mm width and car park-friendly 1880mm height.

The e-Partner rides on MacPherson strut front suspension and coil-spring trailing-arm rear suspension, with electric power steering and four-wheel disc brakes. Its 11.4-metre turning circle is larger than we expected.

There are unpainted dark grey plastic finishes in all the places where bumps, scrapes and wear usually occur in working vans including hubcaps, bumpers, body side-mouldings, door mirrors and handles. The charging port is located above the left rear wheel.

A sealed metal bulkhead with central window separates the cabin and cargo bay, which minimises tyre noise emanating from the rear-wheel housings and doubles as a cargo barrier.

The cabin architecture, with two bucket seats and wipe-clean vinyl floor, is outwardly the same as the petrol version but the driver’s analogue instrument display has been reconfigured for the electric drivetrain.

This includes continual display of energy consumption levels, comprising 'Eco' (minimum consumption), 'Power' (maximum consumption) and 'Charge' (energy recovery from regenerative braking).

It also displays energy consumption by the cabin heating/air-conditioning and battery charge-level, while the dash’s central touchscreen includes an ‘electric menu’ that monitors live energy flows and consumption statistics plus allows scheduling of delayed charging if required.

The Seal has a huge cabin, and in a lot of ways it feels like the large sedans of old. You can sit nice and low in the cabin, and there’s heaps of knee and headroom thanks to its width.

Soft-clad materials for resting your knees and elbows on go a long way towards keeping this car comfortable on longer journeys, and the presence of a digital dash and a holographic head-up display is nice to have compared to the bare-bones dash of the Tesla Model 3.

The wacky rotating central touchscreen feature makes an appearance from other BYDs, but again, it’s a bit silly and I’m not sure how much use you’ll get out of it. Even Apple CarPlay only works in landscape mode, so I didn’t find it useful.

Practicality features are abundant, with a large bottle holder in the doors, and two more in the centre console. One even has a floating floor, so you can push it down to accommodate large bottles if need be.

Dual wireless chargers are always a nice touch, and the bridge-style console has a large pass-through storage area underneath, which also hides the USB-C, USB-A, and 12V outlets. The armrest console box is nice and deep, too.

The back seat is enormous. Possibly one of the largest spaces in this segment. It comes at a cost to boot capacity, but your rear passengers won’t want for space no matter how tall they are.

At 182cm tall I had leagues of airspace behind my own driving position, and the wide cabin, accommodating seats, and flat floor mean the centre position is even useful for a full-sized adult.

Storage comes in the form of three pockets on the back of each front seat, a large bottle holder in the doors, two cupholders in the drop-down armrests, a small tray on the back of the centre console, and a small flip-out cover which reveals a USB-C and USB-A charging port for rear passengers. The rear seat even gets dual adjustable air vents, but no third climate zone.

The massive fixed glass roof looks the business and keeps the cabin airy, just like in the Model 3 and Polestar 2, but I find these big glass fittings tend to cook interiors in the Australian sun.

BYD tells us the tint is so heavy it has a ‘solar transmittance’ of just 16 per cent, but 16 per cent is still a lot in Australian summer. Thankfully, unlike its two rivals, BYD ships the Seal with a fold-out cover screen as standard.

Remember how I said the massive rear seat comes at a cost to boot space? At 400 litres the Seal’s boot is a bit compact, made worse by the fact it’s a sedan and not a liftback, so the access area is a bit narrow.

It could only fit the largest CarsGuide luggage case alongside the smallest one, but not all three including the medium case. This could be a blow to family buyers who need to fit a pram alongside other things.

Under the floor there’s an extra space great for the storage of your V2L adapter and AC charging cable, but there’s also only a tyre repair kit and no spare.

The e-Partner’s 1632kg tare weight is about a quarter of a tonne (247kg) heavier than its 1385kg petrol-engine equivalent, largely caused by the lithium-ion battery pack.

So, even though the electric model has more power (100kW vs 96kW) and torque (260Nm vs 230Nm), the battery ensures it has an inferior power-to-weight ratio, with the e-Partner carrying 16.3kg/kW compared to the petrol’s 14.4kg/kW.

The e-Partner’s 753kg payload rating is also 182kg less than its petrol sibling, so be mindful of these differences if payload is important.

The e-Partner is also rated to tow up to 750kg, but given Peugeot does not publish a GCM figure (how much it can legally carry and tow at the same time) we don’t know if it can haul its maximum payload while towing its maximum trailer weight.

The cargo bay, with 3.9 cubic metres of load volume, is a window-free zone accessed by a sliding door on each side and asymmetrical rear barn-doors that open to 180 degrees for optimum loading access.

With its 2167mm length, 1527mm width, 1243mm height and 1229mm between the rear-wheel housings, it can carry one standard Aussie pallet or two Euro pallets held in place by a choice of six load-anchorage points.

The cargo bay is lined to mid-height and there’s protective mesh over the bulkhead window. However, the bulkhead protrudes into the sliding door openings given the need to allow sufficient cabin space for the seat backrests.

There’s also no load-floor protection provided as standard, so to avoid scratches and dents we’d recommend fitting a floor-liner like the thick rubber one fitted to our test vehicle.

Cabin storage includes a full-width shelf above the windscreen and bins in the base of each door. The dash offers small bottle/cupholders on each side plus a lidded upper glove box and open storage on the passenger side.

The dash extension, where the gear-selector and electronic handbrake reside, offers more open storage as does the floor-mounted centre console.

Our criticisms include the lack of a dedicated storage place for the charging cable, which is supplied in a zip-up vinyl bag.

Although it was sitting on the passenger floor when we collected the vehicle, it was difficult to find a secure place to store it with a passenger aboard. It ended up unsecured in the cargo bay.

The rear barn-doors also do not have any stays to keep them open when positioned at 180 degrees.

As a result, the slightest breeze swings them shut.

And due to the lack of any dedicated bottle-holders in the front door bins, bottles tend to topple onto their sides and can be difficult to extract when driving.

Our test vehicle is available in only one specification, based on the ‘Pro Long Auto’ which means it’s the more work-focused ‘Pro’ model grade with long wheelbase and automatic, which in this application is a single-speed transmission.

With a 100kW/260Nm single electric motor and 50kWh lithium-ion battery, it has an eye-opening list price of $59,990, plus on-road costs.

That represents a substantial 56 per cent increase over its petrol-powered equivalent ($38,388) and optional metallic paint like ours adds $690.

However, the e-Partner has more power and torque with zero drivetrain emissions. It also comes standard with work-focused 16-inch steel wheels and 215/65R16 Michelin tyres with a full-size spare, a toggle-style gear selector, electric parking brake, reversing camera, two-way adjustable leather-rimmed steering wheel, 12-volt accessory socket and USB port plus a four-speaker multimedia system with 8.0-inch touchscreen, digital radio and multiple connectivity including Apple and Android devices.

Each Seal variant gets its own drivetrain outputs, and the mid-spec Premium drives the rear wheels with a 230kW/360Nm electric motor via a reduction gear.

On paper, it’s slightly more powerful than the Model 3 RWD, with more power and less torque than the Polestar 2 Standard Range.

The single electric motor and 50kWh lithium-ion battery combination produces 100kW of power and 260Nm of instant torque.

It also offers three switchable drive modes including Eco (60kW, 190Nm) for minimal performance and energy use, Normal (80kW, 210Nm) which is a happy medium for everyday use and Power (100kW, 260Nm) for maximum performance when hauling heavy loads.

The gear-selector controls Park, Reverse, Neutral, Drive and Brake functions. There's also a button marked B which engages regenerative braking for optimum battery top-ups when driving.

The Mode 3 Type 2 wall-box/public station charging cable is supplied as standard, but buyers can also purchase a domestic wall socket cable for home-charging.

Quickest charge time from 0-80 per cent is 30 minutes using a 100kW DC charger while a 0-100 per cent charge using a single-phase wall-box (7.4kW) takes about 7.5 hours.

Home-charging from 0-100 per cent using a domestic wall socket (2.3kW) takes about 24 hours.

Providing power is a sizable 82.56kWh lithium-ion battery pack, using BYD’s signature weight and space-saving ‘Blade’ form-factor, and the more affordable LFP (lithium iron ferrophosphate) chemistry.

On the charging front, the Seal Premium can top up at 150kW on a DC unit (using a Type 2 CCS connector) for a 10-80 per cent charge in roughly 40 minutes, while on AC its a disappointing 7.0kW.

The 7.0kW inverter means it’s hardly worth plugging the Seal in at a slow public charger when you visit the shops, as you’ll only get about 50km of range an hour. It’s for this reason most cars with batteries this size have 11kW inverters.

Unlike the Model 3 or Polestar 2, though, the Seal features a V2L system, allowing you to power household appliances from its Type 2 charging port.

Claimed energy consumption for the Seal is 14.6kWh/100km which is low, and about what we were seeing on test. It’s a little hard to tell because the trip computer only offers total consumption over the entire life of the vehicle, or for the last 50km, but not for a set trip interval. Weird.

Peugeot claims an official WLTP driving range of 258km. The dash display was showing a projected driving range of 280km when we collected the vehicle.

A few days later when we stopped to top-up the battery at a public charging station, after 135km of unladen city and suburban driving, it was displaying average consumption of 20.4kWh/100km.

When charging was completed, the dash display was claiming 270km of driving range. This had dropped to 194km the following day when we stopped to load the vehicle for our GVM test. Average consumption had also dropped to 19.0kWh/100km.

We then drove 52km with a heavy payload in busy traffic, during which consumption dropped again to 18.8kWh/100km with regular switching between the drive modes.

After unloading and then returning the vehicle to Peugeot, there was still 96km of range remaining and energy consumption had dropped again to 18.4kWh/100km.

So, we covered a total of 271km during our test, of which about one quarter was with a heavy payload.

So, based on its lowest consumption figure, Peugeot’s claimed 258km range in real world driving conditions is pretty accurate by our measure.

I wasn’t expecting the Seal to impress me particularly. After all, it’s in this segment against tough competition, amongst recently updated versions of the Model 3 and Polestar 2, and while the previous BYDs I’ve driven have been a cut above their Chinese contemporaries, they also haven’t done a lot to stand out from the crowd.

Clearly, though, BYD has something to prove with its sporting sedan and the Seal is immediately impressive. The cabin is quiet and refined, the seating position is great it's smooth from take-off.

The steering has an artificial tinge to it removing a bit of feedback from the road, but proves at least quick and accurate at speed, and the handling is superb.

I kept pushing the Seal in my test drive, expecting gnarly characteristics to surface but they didn’t. This sedan grabs onto the road with excellent control and traction at the rear, spurred along by its long wheelbase, and improved tyre choice (Continental rather than the sub-par Chinese rubber worn by the Atto 3 and Dolphin).

While on paper it appears to have at least comparable motor output figures to the Polestar 2 and Model 3 - the Seal Premium doesn’t quite feel as rapid, its electric motor having a more relaxed vibe and responsiveness when you stomp on the go pedal.

This can be tweaked a little by dialling it up to Sport mode, and while it still doesn’t feel quite as breakneck fast as the Model 3, in particular, it’s plenty to be going on with.

The most impressive part of the Seal drive experience, though, is its ride. Ride is a constant problem for EVs as manufacturers go to lengths to tame the additional weight of batteries, but the Seal is the most impressive in its cohort, and by quite a margin.

It’s firm enough to be controlled, but has a lovely soft edge to it, so larger bumps, frequent corrugations, or sharper road imperfections don’t ruin your day.

The Model 3 and Polestar 2, even in their improved forms, are not this good. In a lot of ways the Seal’s suspension tune reminds me of the Mustang Mach-e. It has a soft edge, offset by a bit of secondary jiggle as the car settles, which is its only real blemish.

The Seal has no right being this good. It’s now not just matching its far more established rivals but doing some things significantly better.

It has a comfortable driving position thanks to a reasonably spacious cabin, two-way adjustable steering wheel, left footrest and fold-down inboard armrest.

However, the base cushion feels a tad short for proper upper-thigh support and does not have rake adjustment.

The flat top of the rectangular steering wheel provides a clear view of the instrument display while the flat bottom allows ample driver clearance.

The electric motor with its muted hum delivers a liquid-like flow of acceleration that’s different to a petrol engine.

The lack of engine noise also makes other sounds more prominent, including tyre roar on coarse bitumen surfaces and thumps from the rear suspension over larger bumps.

The extra battery weight is not a noticeable hindrance in stop-start traffic, given the instant torque of the electric motor.

Its location under the load floor also contributes to a low centre of gravity which makes the e-Partner feel well-planted on the road. Even so, it takes a leisurely 11.2 seconds to accelerate from 0-100km/h.

To test its payload rating we forklifted 650kg into the cargo bay which with driver was just under its 753kg limit. The rear suspension compressed 70mm, but there was no bottoming-out over bumps due to large rubber cones positioned inside the coil springs that assist in supporting heavy loads.

We covered more than 50km with this weight in city and suburban driving and its performance was good in all modes including the energy-saving Eco. Energy consumption did not spike as expected.

Our only gripes from a driver’s perspective are the absence of blind-spot monitoring and rear cross-traffic alert, which should be mandatory in all solid-walled vans given the huge blind-spot over the driver’s left shoulder. Relying only on the relatively small passenger door mirror is potentially hazardous.

The other is the cruise control stalk located on the steering column, which is hidden from view by the steering wheel arm. Therefore, it must be operated purely by feel, which can be fiddly and distracting when driving.

Only four from a possible five ANCAP stars for the e-Partner (achieved 2018) and the lack of blind-spot monitoring, rear cross-traffic alert and adaptive cruise control, etc, highlight a safety menu in need of updating.

Even so, it does have front, side and curtain airbags for driver and passenger plus AEB, lane-keeping, audible low-speed pedestrian alert and tyre under-inflation warning.

The long-term ownership aspect for a BYD product is still a bit of a mystery as the current crop of cars have only just landed in Australia in the last year or two, but if it offers you any peace of mind, the Seal is covered by a six-year/150,000km warranty with a separate eight-year/160,000km warranty for the battery pack.

In order to avoid having to have a traditional dealer network, BYD has partnered with MyCar to fulfil servicing. Visits to one of these locations is required once every 12 months or 20,000km whichever comes first, and pricing is fixed for the first eight years, working out to an annual average of $299.

Warranty is five years/200,000km plus eight years/160,000km for the battery. There are also three-year paintwork and 12-year corrosion warranties.

Scheduled servicing is every 12 months/25,000km, whichever occurs first.

The pre-paid service plan price of $1000 covers the first five scheduled services, or just $200 per service.
