BYD Seal-U Range, Efficiency, and Performance as a whole

The BYD Seal U brings a strong blend of smooth performance and outstanding efficiency to the plug-in hybrid SUV market. Buyers can choose between two versions: the Boost and the Design. The Boost variant combines a 1.5-litre turbocharged petrol engine with an electric motor, delivering a combined output of 214 bhp. It feels lively and responsive, achieving 0–62 mph in around 8.6 seconds — more than enough for daily driving and confident overtaking. For those wanting even sharper performance, the Design model steps things up with a more powerful electric motor, producing 319 bhp and cutting the 0–62 mph sprint down to just 5.7 seconds. Thanks to the immediate torque from the electric motor, both variants feel quick off the line and deliver a smooth, refined drive.

Efficiency is another strong suit for the Seal U. The Boost model is equipped with an 18.3 kWh battery that provides up to 50 miles of electric-only range under WLTP testing, making it ideal for city commuting without using a drop of petrol. The Design version, meanwhile, features a larger 26.6 kWh battery, extending the electric-only range to an impressive 78 miles — one of the best figures in its class. Whether you're running daily errands or taking longer trips, the BYD Seal U offers the flexibility of zero-emission driving with the reassurance of a petrol engine for when you need it.

You can tailor your finance plan for your used BYD SEAL U to suit you and your budget, there are three main finance agreements to choose from, our most popular which is Personal Contract Purchase, Hire Purchase and Personal Contract Hire.
