ECO MOTORS NEWS had the opportunity to get hands-on with the BYD SEAL 6 DM-i Super-Hybrid, the Chinese manufacturer’s plug-in hybrid saloon that aims to shake up European standards. A vehicle that embodies the new generation of electrification: accessible and with a long range. For two days, we put it to the test in a variety of conditions: local roads, city centres, motorways and expressways.
First impressions: dynamic elegance, Chinese style
At first glance, the SEAL 6 shows its ambitions. At 4.84 metres long and almost 1.88 metres wide, it is positioned in the large saloon segment. What sets it apart from its competitors is its fastback silhouette, which gives it a resolutely dynamic look. Even though it ends in a conventional boot rather than a hatchback, this rearward-sloping line gives the car a sporty character.
True to what BYD calls ‘Ocean Aesthetics’, the design remains modern and uncluttered. At the front, the SEAL 6 is adorned with sharp, double-L-shaped LED headlights that catch the eye and give it the air of a large European sports saloon, which is quite successful. The flowing, taut lines of the bonnet reinforce this impression of dynamism, while the active grille optimises aerodynamics with a drag coefficient of just 0.25 Cx.
At the rear, it’s modern, recognisable and as faithful as ever to the brand’s maritime inspirations, even if personally, we’re still a little divided on the fastback/classic hatchback combination, as a matter of taste.
A detail that could make all the difference to city-dwellers: the 18-inch wheels with their ‘Flying Axe’ design are set slightly lower than the tyres, which have particularly thick sidewalls. It’s a detail we found pleasing, since this configuration favours comfort and protection for the rims when manoeuvring in town.
The boot has a volume of over 490 litres, which is certainly appreciable and generous, but – and there is a but – access is a little narrow. When it comes to stowing bulky items, such as a large suitcase, this quickly becomes a problem. This is due to the fastback design: you gain in aesthetics, but lose a little in practicality. But that’s far from being a problem: everyday needs are largely covered, and weekends away or holidays are still perfectly feasible for a family.
The interior: sleek, digital and efficient
Let’s climb aboard, where the BYD philosophy is immediately apparent: sobriety, minimalism and everything done digitally. The first thing that strikes you when you get behind the wheel is how accessible the controls are. The controls fall quite naturally to hand. Whether it’s starting the car, operating the electric windows (a classic, but one that can sometimes get lost) or opening the panoramic sunroof fitted to our test model, everything is intuitive and logical.
As with most modern vehicles, everything is centralised on a large touchscreen. Here, BYD has fitted a large 15.6-inch screen, compatible with Android Auto and Apple CarPlay, positioned right in the centre of the dashboard. Compared to what’s available on the market, what I found particularly appreciable was being able to navigate the interface at the click of a button, without plunging into complex menus. Our Comfort version is equipped with heated seats that can be adjusted directly from this same panel. It’s ergonomically designed for real-life use, so there’s no need to fiddle around. On the other hand, as part of the ongoing development process, you have to accept the almost total absence of physical buttons: only a few controls remain, notably on the steering wheel.
As far as the quality of materials is concerned, BYD is pretty well off the mark. There are very few hard plastics in the cabin. The seats are made of perforated textile, are ventilated and heated, and also have a memory function. The materials are sober and of a frankly very satisfactory quality, even if you can imagine that you won’t find the level of finish of a German premium saloon or a British SUV; in any case, that’s not the brand’s ambition. A package perfectly suited to the vehicle’s price positioning.
At the rear, for a vehicle almost 5 metres long, there’s plenty of room to spare. And the SEAL 6 delivers. Thanks to a generous wheelbase of 2.79 metres, three real seats are available, with a bench seat of the same quality as up front. Long journeys are no torture. There’s plenty of legroom and decent headroom, so when it comes to transporting children, friends or even belongings, it clearly gets the job done.
Behind the wheel of the BYD SEAL 6 DM-i Super-Hybrid
This 2ᵉ hybrid model from BYD that we tested benefits from Dual Mode Super Hybrid technology, which intelligently combines pure electric propulsion and a combustion engine in series or parallel. The system features a combustion engine developing around 98 bhp, combined with an electric motor delivering up to 212 bhp in Comfort trim, for a combined output of 217 bhp.
In pure electric mode, it’s silent and smooth when you ramp up the power – exactly what you’d expect from city driving in a hybrid. It also handles well for its size. The range in 100% electric mode can reach up to 140 km WLTP thanks to the 19 kWh battery, which more than covers the daily needs of most motorists.
But as soon as you apply a little more pressure to the accelerator, the vehicle reveals its true character. The SEAL 6 DM-i has the punch of an electric car, with very strong instantaneous power. Personally, I really enjoyed driving the SEAL 6. BYD has clearly aimed for the best of both worlds: the range and versatility of the combustion engine combined with the power, smoothness, silence and environmental credentials of electric motors. The system intelligently manages the transition between modes, and most of the time you don’t even feel when the combustion engine takes over.
Driving the SEAL 6 on fast roads is just as enjoyable. It’s well anchored to the ground, thanks in particular to its high weight (over 1.7 tonnes), and its 2.79-metre wheelbase gives it reassuring stability, even at high speeds. Handling is firm and confident. Dynamic handling is well-balanced, and the steering is sufficiently precise, even if it can sometimes lack a little sparkle in tight sequences.
In terms of fuel consumption, the hybrid system is extremely efficient. The combined range can reach around 1,350 kilometres WLTP, with a claimed fuel consumption of around 1.5 to 1.7 L/100 km in the combined cycle. In reality, in a variety of driving conditions (city, road, motorway), fuel consumption remains very low, well below what an equivalent internal combustion vehicle would achieve: another point for the hybrid.
Conclusion: the affordable hybrid that keeps its promises
It’s hard to remain unmoved after this test drive. The BYD SEAL 6 DM-i Super-Hybrid brilliantly combines efficiency, range, versatility and a formidable price tag. With an entry-level price of under €40,000, it is clearly aimed at customers looking for efficiency and rationality, without sacrificing driving pleasure or comfort. It’s not perfect, but its qualities far outweigh its faults. It was a very pleasant test drive: we enjoyed ourselves, and driving pleasure is ‘almost’ the most important thing.
Admittedly, the interior materials don’t rival those of a Mercedes E-Class, BMW 5 Series or Audi A6. But for the price on offer, the value for money is undeniable. BYD is true to its ambitions: to be the market leader by focusing on technology, range and price.
