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.
I think auto journalists are supposed to see vehicles a bit like parents see their children. You know, view them all as equals. No favourites. That kind of thing.
But I'm going to let you in on a tiny little secret, just between us. I liked this potent M2 before I even sat in it. And I like it just a little bit more than I love other bite-sized performance cars.
In fact, I like it more than I like bigger, more powerful, and more expensive models in the BMW M family.
You could almost call the B4 S the anti-M4. It's still fast and practical but from a completely different perspective. It's much more a grand tourer than the M4 and even with the Akrapovic exhaust (usually a byword for joyous, anti-social racket), subtle.
For some, the price won't matter because the Alpina delivers what they want - M4-like straight line performance without the histrionics or the uncompromising chassis. And there's also a bit of that perverse exclusivity of the styling that you won't get anywhere else.
Proving good things still come in small packages, the pint-sized M2 remains my pick of the BMW M range. It's not the perfect daily drive, but I reckon the fun outweighs the foibles.
