Chrysler plans to bring a four-door retractable-top car to market. The new convertible sedan will based on the next-generation Chrysler Group LX platform and will arrive no earlier than the 2010 model year.
Helios concept (ASC design), based on a 300C four-door sedan, was unveiled at the Detroit show last year. The Helios is a rag top with a lattice structure to provide expected levels of body rigidity. But Chrysler has rejected the ASC design and chosen another designers to build its 300 retractable sedan. A complex folding steel roof covering four doors in a large sedan seems difficult, but if Chrysler can carry this off, a Chrysler 300 Convertible will add more prestige to keep it at the forefront of leading-edge design.
