When BMW's structural engineers were developing the Z4, they created a body/chassis structure with exceptional stiffness for a roadster. The team achieved 21 Hertz # – truly outstanding for a roadster, and close to the 25-26 Hz of today's BMW sedans. To attain this remarkable rigidity, the engineers incorporated a number of special structural features, including Y-form front structural members, ultra-strong side sills and underbody, 'thrust plates' that add rigidity to the front and rear suspension attachment points, and extensive use of high-strength steels. To save weight and help optimize front/rear weight distribution, the Z4 hood is of aluminum. Rollover protection is provided by an exceptionally strong windshield frame and two rollbars mounted behind the seats. bmw z4 reviews,transmission, structural,front,weight,valves, rigidity,rear,engine,specs, performance,price,cost,sale, interior,exterior |
