2018 BMW Alpina B4 Summary

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.

2026 BMW i Series Summary

There are a lot of big numbers surrounding the BMW iX3, the German brand’s new-from-the-ground-up EV that acts as the flagbearer for its future-facing Neue Klasse (or New Class) architecture, designed to distil all the ingredients that make a BMW a BMW, and then electrify for them for the post-ICE (internal combustion engine) era.

But the one that really stood out? 805. That’s how many kilometres of driving range the iX3 will deliver, though admittedly in its most efficient and least exciting driving modes. That is bonkers, right?

It’s worth pointing out the first BMW i3, which only launched a decade-or-so ago, delivered more like 150km on what would have been the WLTP cycle, if it had existed then. Talk about leaps and bounds.

A good start for the newest BMW EV, then. But what else does the iX3 have to offer?
