Based on the terminology from various Bosch technical books and the Automotive Engineering Handbook, as well as various writings and collections of terms, automotive professionals are provided with a compilation of the current technical vocabulary in German, English, French, and now also in Spanish. This is important for anyone who needs to remain conversationally competent in international business and requires accurate translations for new systems and products. The expansion of the technical dictionary to include Spanish addresses the increasing internationalization of business. All terms are now listed in this fourth language. The vocabulary has been thoroughly reviewed, with outdated terms removed and new terms added.
