Designed around the whole retractable hard top concept, the 488 Spider has a spaceframe chassis made of 11 different aluminium alloys combined with other noble metals such as magnesium, each one used in a highly specific way. This yields the same torsional rigidity and beam stiffness figures as the Coupé, improving the chassis’ performance by 23% over that of its predecessor.Subscribe ferrariworld: http://www.youtube.com/subscription_center?add_user=ferrariworldFollow us on Facebook http://www.facebook.com/Ferrari and Twitter http://twitter.com/ferrariFerrari Since 1947http://www.ferrari.com
