I research and write blogs on what’s happening in the EV-world.
The electric vehicle market has undergone significant changes in the last ten years.
Unlike the original BMW i3 hatchback, which focused on urban mobility and innovative lightweight construction, the 2026 BMW i3 is an executive electric saloon built on BMW’s dedicated Neue Klasse platform. It has been designed to compete directly with vehicles such as the BYD Seal, Tesla Model 3 and Polestar 2.
On the other hand, the BYD Seal showcases the newest generation of electric vehicles, merging advanced battery technology with remarkable performance and affordability.
While these cars cater to different audiences, many compare them whilst browsing new cars. Understanding the strengths and limitations of each can help you make the right decision for you.
Design and Practicality
The 2026 BMW i3 marks a new chapter for BMW’s electric vehicle line-up. Built on the dedicated Neue Klasse platform, it serves as the all-electric equivalent of the BMW 3 Series, combining executive saloon styling with the brand’s latest EV technology. The cabin is expected to feature BMW’s new Panoramic iDrive display, a minimalist design and a greater emphasis on digital technology and sustainable materials.
In contrast, the BYD Seal adopts a sleek executive saloon design with a modern, high-quality interior. The cabin features a 15.6-inch rotating touchscreen, supportive seating and generous passenger space, making it well suited to both daily commuting and longer journeys. While the Seal places a strong emphasis on practicality and technology, the 2026 BMW i3 is expected to introduce BMW’s latest digital cockpit, giving drivers two distinctly different approaches to interior design and user experience.
Performance
BMW has developed the Neue Klasse platform to deliver improved efficiency, driving dynamics and responsiveness. The 2026 BMW i3 is expected to feature BMW’s sixth-generation eDrive technology, offering greater efficiency and performance than the brand’s current electric models. While final powertrain specifications have yet to be confirmed, a range of variants is anticipated to cater for both everyday driving and performance-focused buyers.
The BYD Seal is available with a choice of rear-wheel drive and all-wheel drive powertrains. The range-topping Excellence AWD model delivers brisk acceleration, reaching 0-62 mph in just 3.8 seconds, while also providing composed handling and a comfortable ride that makes it well suited to both daily commuting and longer journeys.
For drivers considering the latest electric saloons, the BMW i3 is expected to prioritise the engaging driving dynamics the brand is known for, while the BYD Seal already offers impressive performance, refinement and value in a production-ready package.

Range and Charging
One of the biggest expected improvements for the 2026 BMW i3 is its driving range.
BMW has confirmed that its sixth-generation eDrive technology has been developed to improve efficiency and extend range. The company has stated that certain Neue Klasse models are targeting up to 562 miles (WLTP), although the final range and battery specifications for the production BMW i3 have yet to be confirmed.
The BYD Seal offers a WLTP range of up to 354 miles, depending on the model, with real-world driving typically delivering around 250 to 300 miles depending on conditions. Combined with BYD’s Blade Battery technology, which is designed to maximise safety, durability and efficiency, the Seal provides a practical balance of range and everyday usability.
When it comes to charging, BMW has confirmed that Neue Klasse models will feature an 800-volt electrical architecture, enabling faster charging and shorter charging times than previous BMW electric vehicles. Meanwhile, the BYD Seal supports DC rapid charging of up to 150kW, allowing it to charge from 10% to 80% in around 37 minutes under ideal conditions.
Technology
Technology is expected to be one of the key strengths of the 2026 BMW i3. It is set to introduce BMW’s new Panoramic iDrive display and Operating System X, alongside enhanced voice controls, over-the-air software updates and advanced driver assistance features.
The BYD Seal is equally well equipped, featuring a 15.6-inch rotating touchscreen, wireless Apple CarPlay and Android Auto, a comprehensive suite of driver assistance systems and over-the-air software updates. Together, these features help keep the vehicle connected, secure and up to date throughout ownership.

Through salary sacrifice
The BYD Seal has attracted plenty of attention by offering premium features at a competitive price. With generous standard equipment and impressive performance, it represents excellent value in the electric saloon segment. Through salary sacrifice, you can drive the BYD Seal from £488/month for a 20% taxpayer, or £429/month for a 40% taxpayer.
The 2026 BMW i3 is expected to sit at the premium end of the electric saloon market, reflecting its next-generation technology, executive positioning and advanced electric platform. While official pricing has yet to be confirmed, it is expected to cost between £50,000 and £60,000, placing it alongside models such as the BMW i4 and BMW i5. Both are already available through salary sacrifice, with monthly costs typically ranging from around £700 to more than £1,000, depending on the model and specification.
For drivers seeking BMW’s latest electric technology, the new i3 could become an attractive addition to salary sacrifice schemes when it becomes available.
