Mercedes-Benz A200 vs BYD Seal

What's the difference?

Meet the world’s most aerodynamically efficient passenger car. Mercedes-Benz says the drag co-efficient for this new sedan version of its fourth-generation A-Class is the lowest ever measured for a passenger vehicle.

Which is quite a claim, but you only have to look at it to see how much work has gone into marrying good looks with slippery aero performance.

The A-Class sedan is substantially longer and fractionally taller than its hatchback sibling, but does that mean it’s better, or simply different?

BYD. The three letters which keep auto executives from the world's top brands up at night.

The brand’s meteoric rise in Australia from a trickle of imports to a torrent of Chinese-built EVs, outselling even Tesla in the first month of 2024, is testament to this relative newcomer’s ability to surprise and impress its buyers and the industry as a whole.

The car we’re looking at for this review, the Seal, could be its biggest challenge yet. Not only does it have to compete head-to-head with the car which put EVs on the map for mainstream buyers - the Tesla Model 3 - but it also has to vie for a share of the increasingly shrinking sedan market.

So, what’s the deal with the Seal? Is it any good? And, why did BYD choose to name it after a marine mammal? Read on to find out.
