I'm happy very good site http://fittor.fun/ying-noey/ momsn The most crucial battle of all – these are performance cars after all. The Porsche Boxster has the performance edge, on paper at least. It uses a comparatively huge mid-mounted 3.4-litre six cylinder engine that produces a whopping 315hp at 6,700rpm. The Alfa Romeo 4C, in contrast, uses a tiny 1,750cc four cylinder turbocharged engine that manages just 240hp at 6,000rpm.
