The BYD Seal U DM-i is a significant step forward in plug-in hybrid technology, offering real-world versatility for families and business users alike.
With up to 78 miles of pure electric range on the larger battery variant, most daily commutes can be completed on electric power alone, whilst the efficient petrol engine extends total range to approximately 671 miles for longer journeys without range anxiety.
Built on BYD's advanced DM-i (Dual Mode intelligent) super hybrid platform, this intelligent SUV seamlessly switches between electric and hybrid modes to deliver optimal efficiency.
As such, the system prioritises electric driving wherever possible, only engaging the petrol engine when needed for acceleration or to extend range, resulting in exceptionally low running costs and emissions.
A Grainger Motor Group we stock the BYD Seal U-DM i and offer test drives at our showrooms in Mantles BYD Royston and EMG BYD Bury St Edmunds, King's Lynn, and Spalding.
The BYD Seal U DM-i is available with two battery configurations, each offering different electric range and performance characteristics. The 18.3kWh battery in Boost and Design trims delivers up to 43 miles of electric range, whilst the larger 26.6kWh battery in the Comfort model extends pure electric capability to an impressive 78 miles.
Power outputs range from 217PS in the front-wheel-drive Boost and Comfort models to a muscular 323PS in the all-wheel-drive Design variant, which features dual electric motors for enhanced traction and performance. The Design accelerates from 0-62mph in just 5.9 seconds, delivering sports car performance with family SUV practicality.
DC rapid charging support reaches up to 80kW on the Comfort model, enabling a 30% to 80% charge in approximately 30 minutes at compatible charging stations. Home charging using a 7kW wallbox takes around 4 hours for the larger battery, making overnight top-ups convenient and cost-effective.
The efficient petrol engine also charges the battery whilst driving, ensuring you always have electric range available.
At 4,775mm long, 1,890mm wide and 1,670mm tall, the Seal U DM-i offers generous SUV proportions whilst remaining easy to manoeuvre in urban environments. The long 2,765mm wheelbase maximises interior space, creating a spacious cabin with excellent headroom and legroom for all passengers.
Following BYD tradition, the Seal U DM-i features a 12.8-inch rotating touchscreen that switches between landscape and portrait orientations to suit your preference.
The system supports wireless Android Auto and Apple CarPlay connectivity, whilst voice control allows hands-free operation of navigation, media and climate functions.
A 10.25-inch digital instrument cluster provides comprehensive driver information, including speed, battery level, range, navigation guidance and hybrid system status. The clear graphics and customisable layouts ensure essential information remains easily visible in all driving conditions.
The cabin showcases high-quality materials throughout, including vegan leather upholstery, soft-touch dashboard surfaces and brushed aluminium accents. Ambient lighting with multiple colour options creates a sophisticated atmosphere, whilst the panoramic sunroof enhances the sense of space and airiness.
Heated front seats and a heated steering wheel ensure comfort during colder months, whilst dual-zone climate control allows the driver and passenger to set individual temperature preferences.
The Seal U DM-i's heat pump climate system significantly improves efficiency in cold weather, preserving electric range whilst maintaining cabin comfort. This advanced technology uses waste heat from the electric motors and battery to warm the interior, reducing energy consumption compared to traditional resistive heating systems.
Standard safety equipment across the range includes Adaptive Cruise Control with Stop & Go functionality, Lane Keeping Assist, Lane Departure Warning, Blind Spot Monitoring and Rear Cross Traffic Alert.
The 360-degree surround-view camera system makes parking and manoeuvring in tight spaces effortless, displaying a bird's-eye view of the vehicle's surroundings on the central touchscreen.
The Seal U DM-i's suite of driver assistance systems includes Automatic Emergency Braking with pedestrian and cyclist detection, Traffic Sign Recognition, Driver Attention Alert and Intelligent Speed Assist. These technologies work together seamlessly to reduce driver workload and enhance safety on every journey.
Built using high-strength steel construction with strategically reinforced crumple zones, the Seal U DM-i provides comprehensive occupant protection in the event of a collision. Expect six airbags as standard, including side curtain airbags protecting front and rear passengers, which complements the robust body structure.
BYD's innovative Blade Battery technology, featured in the Seal U DM-i, has passed the rigorous 'nail penetration test' without thermal runaway or fire, demonstrating exceptional safety credentials. The battery pack's structural integration also contributes to overall vehicle rigidity whilst maintaining a low centre of gravity for improved handling dynamics.
Thanks to the efficient packaging of the hybrid powertrain, the Seal U DM-i offers a genuinely spacious five-seat cabin with ample headroom and legroom in both rows.
The flat rear floor ensures comfortable seating for three adults across the back seat, whilst large door apertures provide easy access.
Front seat passengers benefit from electrically adjustable seating on Comfort and Design models, including lumbar support for enhanced long-distance comfort.
The boot provides 425 litres of storage space with all seats in use, sufficient for family luggage or weekly shopping. Folding the 60:40 split rear seats creates a generous load area ideal for larger items, whilst underfloor storage compartments keep valuable items secure and out of sight.
Throughout the cabin, clever storage solutions maximise everyday practicality. A large centre console storage bin, wireless phone charging pad on higher trims, bottle holders in all four doors, rear seat armrest with cupholders and multiple USB-C charging ports ensure occupants remain comfortable and connected on every journey.
