I posted this in the 2 series forum
Was able to get my hands on this juicy nugget! See full details below.
But in short: Special editions of the 3 & 4 series including:
M Performance Power Kit and M Performance Exhaust, output climbs to 335 HP & 332 lb./ft torque – reducing the 0-100 km/hr time to an estimated 4.5 seconds (M235 total output goes unchanged).
Furthermore, these Editions will come with the full M Performance Aerodynamics kit and segment exclusive 20” Alloy wheels for the 335/435 and 19” for the M235
Some select "individual" colours are available as well. They are really making it hard for me to stay in my current lease
