Just a couple weeks ago, BMW announced that it will offer a $550 Performance Edition package on single-turbo (N55 engine) 335i coupes and sedans; better still, existing 335i owners could retrofit the package to their cars. In a press release today, however, we discovered a small addition BMW snuck in: owners of the 135i with the N55 also can have the dealer-installed package added to their rides.
The 335i Performance Edition package is a massive bargain and includes such goodies as special badging, black grilles and grille surrounds, and an output increase of 20 hp, for a total of 320. Torque increases to 332 lb-ft on cars with an automatic transmission and 317 lb-ft for those with a stick. BMW hasn’t announced pricing for the retrofit package yet—it will do so in August—but we can’t imagine it will be much more than the $550 it takes to bolt this kit to a new Bimmer. We have clocked a stock 300-hp 135i to 60 mph in just 4.8 seconds, and we look forward to seeing what sort of whittling another 20 hp could do to that time.
