Germans do speak English, especially among the youth. In fact, it’s highly improbable to find anyone who is NOT proficient in English, or not willing to use it. Obviously they’d prefer to speak in their own language in their own country. However, they are quite flexible on this matter and will try everything to understand you and be understood. They are quite amazing about the language barrier. If they notice your German is poor but you understand some words and are making an effort, they will answer in German in order to help you improve your skills.
Not anymore! Of course, most new designs lose money when first introduced anyway. It is true that Prius initially lost money. Building the hybrid did cost more than it was sold for, at first. But over the years, Toyota managed to overcome production expenses to reduce that cost to below the window-sticker price. By late 2002, the THS design had proven so successful that Toyota decided to invest again. That made Prius, once again, unprofitable. Fortunately, the new HSD design was created for use in the entire fleet of Toyota passenger vehicles, every single model... which means it is quite inappropriate to place the entire burden of that research & development solely on just one vehicle, Prius.
