Alpina’s range of 3 Series and 4 Series-based B3 and B4 models have been treated to an engine upgrade of 23kW/60Nm taking output to 324kW/660Nm. The update brings an S to the boot badge and drops the 0-100km/h dash to between 4.2 and 4.3sec for the range of sedan, coupe, wagon and convertible options.

Pricing has also been revised, chopping between $11,000 and $13,000 from the ask, but is it enough to steer buyers away from something with an M-badge?
