The prohibitive expense of carbon fiber and its painstaking production process has conspired to limit the role of composite chassis to race cars and ultra-pricy supercars like Porsche's Carrera GT. But now, Italy's ATR Group is hoping to change all of that. The firm, having already gained respect (and business) for its work with Porsche, Ferrari and Bugatti, is setting its sights on a lower-priced carbon-fiber composite spaceframe for use in GT-class automobiles. Positioning its flexible technology as an alternative to aluminum chassis construction, ATR believes it can manufacture twenty one-piece tubs per day at a cost that would put it in the realm of many GT offerings. ATR is targeting whips that orbit the Maserati's Spyder's pricepoint.
