Sportec, a Swiss tuner, presents their M135i F21 hatchback at the Geneva Motor Show 2013. The two stages of the tuning program include software tuning which upgrades the M135i’s N55 power output to 355 hp (from the factory 315 hp), and the software upgrades plus downpipes and new exhaust system (with titanium tail pipes) which give the M135i a total of 370 hp and achieves 0-62 mph in 4.6 seconds, with a
top speed of 171 mph. The Sportec M135i sits on lightweight 19″ forged SP10 wheels. What do you think of its look?
