A few weeks back, BMW announced that it would make a Performance Edition Package available to owners of N55 powered 335i coupes and sedans.
Now, the company has announced that a variation of that same $550 package will also be offered on the 135i as well, with dealers providing it as a retrofit on current models. Said package includes black grille surrounds, special badging and some tweaks to the single turbo engine, resulting in an additional 20 horsepower (for a total of 320 hp) and a boost in torque (to 332 lb-ft on automatic equipped cars; 317 on those fitted with a proper gearbox. Should be the other way around if you ask us.
