BMW 230i vs BMW Alpina B4

What's the difference?

If one is good, two must be better, right? Or twice as good. The question is whether that simple equation adds up for BMW's upgraded 1 and 2 Series siblings – the former, a range of five-door hatches, the latter, a line-up of cabriolets and coupes, with a major addition in the shape of the full-house, performance-focused M2.

Prices are up, and changes are mostly under the skin, so you're not getting  big visual bang for your extra bucks. But the new and improved 2 has plenty to offer when it comes to added spec and tech.

BMW invited us to the new car's Australian launch program along Tasmania's wet and wild west coast.

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.
