2012 BMW 328i dyno run suggests it's underrated

BMW is earning quite the reputation of underrating its turbocharged engines. From the early days of the N54 twin-turbo inline six, through the later N55 single-turbo iteration and straight on to the 2012 M5's turbocharged V8, the crafty Bavarians have always erred on the low side with their factory-quoted power figures. According to the dyno run that you'll see after the break, the tradition continues with BMW's new twin-scroll turbocharged four-cylinder inline N20 engine that sees duty in the 2012 328i.
