The electric SUV market has never been more competitive. In 2025, the global best-seller – the Tesla Model Y – faces a formidable new challenger from China: the BYD Sealion 7. So the burning question is: Has BYD really built a better car than Tesla?

Design & Aesthetics

The 2025 Tesla Model Y retains its familiar minimalist design language – smooth lines, flush door handles, and a clean front fascia. Inside, the controversial “no-buttons” cabin continues, with everything controlled through a central 15-inch touchscreen.

In contrast, the BYD Sealion 7 brings a fresh and aggressive look. Sleek LED headlights, a bold and muscular body, and available 21-inch alloy wheels give it a strong presence. The interior is where BYD truly shines: a digital cockpit, a 15.6-inch rotating center screen, eco-leather materials, and customizable 128-color ambient lighting create a more premium, high-tech feel.

Score: Sealion 7 – 1, Model Y – 0

Performance & Technology

The Model Y Dual Motor AWD version goes from 0–100 km/h in about 5 seconds, while the Performance variant does it in just 3.5 seconds. Tesla has tweaked the suspension and steering, and introduced FSD Beta v12 for improved driver assistance.

Sealion 7 holds its ground impressively. The AWD variant delivers 530 horsepower and accelerates from 0–100 km/h in just 3.8 seconds. BYD also introduces its new iTAC (Intelligent Torque Adaption Control) system, designed for better handling on slippery surfaces.

However, Tesla still dominates in software ecosystem and over-the-air (OTA) updates, especially in self-driving tech.

Score: Sealion 7 – 1, Model Y – 1

Range & Charging

The 2025 Model Y offers between 455 to 542 km (WLTP) depending on the battery version. Tesla also boasts the most extensive fast-charging network globally, with its Supercharger system supporting up to 250 kW.

BYD’s Sealion 7 uses its innovative Blade Battery, renowned for safety. The AWD version achieves around 520 km of range, but its DC fast charging peaks at 150 kW, which is noticeably slower than Tesla’s.

Score: Model Y – 2, Sealion 7 – 1

Price & Value

In China and several Asian markets, the BYD Sealion 7 undercuts the Tesla Model Y by 10–20%, despite offering more upscale features and finishes. This makes it a highly attractive value proposition.

BYD is also rapidly expanding its global service and dealership network. While it can’t yet rival Tesla’s global reach, its momentum is impressive.

Score: Model Y – 2, Sealion 7 – 2

Verdict: Who Wins?

This 2025 showdown between Tesla Model Y and BYD Sealion 7 shows just how far Chinese EVs have come.

If you prioritize longer range, faster charging, and a mature software ecosystem, the Model Y remains a strong contender.

But if you value modern design, a luxurious cabin, and a better price-to-feature ratio, the BYD Sealion 7 may actually outshine Tesla in key areas.

So, has BYD built a better car than Tesla?
The answer is: Possibly – depending on what you’re looking for.
