Toyota's Prius has been around since 1997 and we've seen its current iteration since 2004. So, four years later, it's sure to have been passed by when it comes to green automotive technology. Right? Maybe not, as the world's most popular hybrid has just won the Greenest Technology of the Year Award of the British Technology Awards. In truth, Toyota's Hybrid Synergy Drive technology still makes the Prius the most fuel efficient vehicle in the United States and a true alternative to diesels in Europe, but it definitely is challenged by the sophisticated 2-Mode hybrid system developed by GM, Chrysler and BMW. In the public's eyes, though, nothing quite touches the Prius when one thinks of green automotive technology. The British Technology Awards are voted on by readers of Computeractive and Personal Computer World as well as online at the Award's home site. Other award-winners include the Apple iPhone, BBC iPlayer and the Nintendo Wii.
