When choosing a BYD, one of the biggest decisions buyers face is selecting the right trim level. Many BYD models, including the popular BYD SEAL and BYD SEALION 7, are available in two premium trim options: Design and Excellence.
Both trims deliver BYD’s signature blend of cutting‑edge technology, high‑quality interiors, and impressive electric performance. However, each is engineered with a different type of driver in mind. Here’s a clear, straightforward guide to help you decide which one suits your lifestyle best.
BYD Design: premium, efficient, and balanced
The Design trim is the entry point into BYD’s premium offering, but ‘entry‑level’ doesn’t tell the full story. In fact, Design is often praised for offering an exceptional balance of performance, comfort, and range, making it a popular choice for everyday UK driving. Design models feature a single electric motor (usually rear‑wheel drive), which helps maximise efficiency and driving range without sacrificing refinement. This makes the Design trim ideal for commuters, families, and long‑distance drivers who want effortless electric performance with lower running costs.
Even at this level, Design comes generously equipped. Depending on the model, you can expect features such as LED headlights, panoramic glass roof, heated front seats and steering wheel, BYD’s signature 15.6‑inch rotatable touchscreen infotainment system, and advanced driver assistance and safety technology. Thanks to its lighter drivetrain, Design trims typically offer the longest driving range in the line‑up, making them a strong choice for drivers who regularly travel further afield or rely on motorway journeys.
Models available in the Design trim are the BYD DOLPHIN, BYD SEAL U DM-i, BYD ATTO 3, BYD SEALION 5 DM-i, BYD SEALION 7, and BYD SEAL.
BYD Excellence: high performance and ultimate specification
If you’re looking for maximum power, enhanced traction, and the highest level of equipment, the Excellence trim delivers exactly that. Sitting at the top of the range, Excellence models are designed for drivers who want their electric vehicle to feel as exciting as it is luxurious. Excellence variants introduce a dual‑motor all‑wheel‑drive system, significantly increasing power and acceleration while providing added grip and confidence in all weather conditions. This performance‑focused setup allows certain BYD models to achieve rapid 0–62mph times, transforming everyday drives into something far more engaging.
In addition to increased performance, Excellence also builds on the already strong Design specification with extra technology and comfort enhancements. Depending on the model, these may include a head‑up display, electrically adjustable and memory front seats, and additional interior refinement and premium detailing. While the extra performance does result in a slightly reduced driving range compared to Design, many drivers find this a worthwhile trade‑off for the added power, reassurance of all‑wheel drive, and flagship features.
Models available in the Excellence trim are the BYD SEAL and BYD SEALION 7.
Design vs Excellence: which one is right for you?
Choosing between Design and Excellence ultimately comes down to how you plan to use your BYD. Design is ideal if you prioritise driving range and efficiency, want a premium specification without unnecessary extras, mainly drive in urban or motorway conditions, or are looking for excellent value in a high‑quality electric vehicle.
Excellence is best if you enjoy stronger acceleration and performance, want all‑wheel drive for added confidence, prefer the highest level of in‑car technology, or are looking for a true flagship EV experience. Both trims reflect BYD’s commitment to generous standard equipment, advanced battery technology, and refined design, ensuring there’s no wrong choice – just the right one for your needs.
