smart #5 和极氪 7X 是什么关系？同平台兄弟怎么选？

They're built on the same SEA3 platform and share the same 100 kWh battery and 800V architecture . Think of it this way: the Zeekr 7X is the tech-focused, performance-oriented choice (air suspension on Performance variant, slightly higher power) . The smart #5 is the lifestyle, design-led choice – with Mercedes-Benz styling, a luxurious Sennheiser sound system, and unique "Leo" the lion AI avatar . If you want raw specs, go Zeekr; if you want character and cabin experience, go smart .
