One of our lovely specialist BMW tuners is readying a pretty important unveil for the upcoming Geneva Motor Show. Scratch that, it’s several months away but we know what’s happening.

The Swiss show will be the stomping ground for the unveiling of the Alpina B3 S. The current model has it’s charm, but once it goes F30, it should be even more interesting.

With the new car there’s plenty going to change but apart from the name, Alpina is going to stick with the familiar idea of B3 BiTurbo power.

BMW manages it pretty great but we know that Alpina will churn out some serious extra grunt from that 3.0 liter straight six cylinder engine well beyond the current stages.

400 horsepower was what they were capable of producing with the previous version of the car so the new one should go beyond that with at least some 20-30 extra ponies.

Aside from the fact the performance figures are pushed into M3 territory, the Alpina B3 S will almost certainly stick to the family theme.

That means it will ride brilliantly and the suspension will still be sporty when it’s called upon. That’s something BMW themselves have had a few issues with taming.

It will be interesting to see just how Alpina will do afterwards. Though there’s plenty of customers interested in a great cruiser with some performance on it, the 328i still makes a case for itself.

Seeing an Alpina badge on it, some 300 or more horses under its bonnet and a properly comfy ride should certainly tempt plenty of customers.

Then again, is that what Alpina is really about?
