BYD Sealion 7
VS
The BYD Seal U brings crossover practicality and a higher driving position for buyers after everyday versatility, while the sleeker BYD Sealion 7 swaps that raised stance for a lower, sportier profile and crisper road manners. Choose the Seal U for family-friendly space and comfort, or the Sealion 7 if you want sharper looks and a more engaging drive—both pack BYD’s electric tech, so it’s mostly a matter of shape and attitude.
BYD Seal U
Tesla Model Y
VS
The BYD Seal U punches above its price with a sleek fastback profile, surprisingly sporty handling and a tech-packed interior that makes it a compelling foil to the more familiar Tesla Model Y. If you prize Supercharger convenience, software polish and stronger resale you’ll gravitate to the Model Y, but for outright value, plush appointments and clever battery tech the Seal U is the cheeky underdog your bank account will high-five.
