Unveiled earlier this year as a concept, the BMW M135i takes new shape as it is set to go on sale at the end of this year. While most of the body profile remains the same as the concept, the Twin Turbo power-plant was swapped for a single turbo N55 series engine, aiding in less fuel consumption and lower CO2 emissions. Further improvements were also made to the suspension, steering and powertrain. Shown in this cat-and-mouse style video, the 5-door and the 3-door trims are seen racing down a rain-soaked container yard showcasing the vehicles’ handling capabilities. The distinct sounds of the engine followed by deep exhaust notes remind us why this car features the fabled M badge.
