BMW Alpina B4 vs BYD Sealion 7

What's the difference?

If you're looking for a sleek, two-door coupe with a sparkling chassis, rear-wheel drive and a charismatic turbo straight-six, BMW has you covered with about eight choices. That should be that, then. But wait. There's more. 

Since 1965, Alpina - the name of a resurrected a typewriter company - has collaborated closely with BMW to produce distinct, high performance Alpina-badged cars. It actually started with a Weber dual-carburettor unofficial conversion for the BMW 1500 in 1962 and over the years built into a racing operation winning championships and races like the Spa 24 Hours.

Alpina returned to Australian shores in 2017 after a long hiatus with a new range including the BMW 4 Series based B4. Not long after, BMW updated the 4 in what it calls LCI (Lifecycle Impulse), so Alpina followed suit with a price drop, new gear and called it the B4 S.

Looking across BYD's line-up, you'd think you were reading the attractions for the local aquarium! And now the Sealion 7 has entered the splash zone, or more accurately, the most popular car segment - the mid-size SUV.

It fights for pole position against the long-running electric favourite, the Tesla Model Y but newcomer Cupra Tavascan also offers some sporty competition.

For this review we're testing the flagship Performance grade to see whether or not it offers family-friendly fun.
