I've been following advances in electric cars for nearly 50 years and advances in hybrids for 15. I started following electric cars while writing a paper in history class in seventh grade on current events. I started following hybrids when the Honda Insight was released in 1999. I also started following fuel-cell cars about that same time. The Xybrid expands on hybrid technologies, discussing new, potential, and conceptual technologies. If you're interested in cars, and especially if you're interested in hybrids and electric cars, then this book is for you, whether you understand how cars work or not.
