Product Information Boxster/Boxster S Foreword After eight successful years, the now classic Boxster (986) is to be succeed- ed by the new Boxster (987). A daunting challenge by any measure, which the new Boxster generation meets with a wealth of technical, design and stylistic innovations. This training brochure provides detailed information on the many innovations of the new Boxster. It also looks at the cars’ strategic competitors. The aim of this brochure is to provide the international Porsche sales organisa- tion with the ability to advise customers extremely competently concerning the two new Boxsters. We have therefore taken particular care to supply extensive background information which encloses not only the description of the technical conversion but also the related advan- tages of the product. Thus, the present Product Information includes information tailored to the customers’ or prospects’ needs and purchasing motives. This knowledge naturally should be used se- lectively when offering professional tech- nical advice. Dr. Ing. h.c. F.
