AutoWeek has an interview with DCX board member in charge of R&D Thomas Weber about climbing vehicle weights. Weber wants to halt the seemingly inexorable climb in vehicle weight, which is particularly difficult as we move to alternative power-trains. Batteries are heavy, even lithium ion types. According to Weber, weights have climbed between one-half of 1 percent and 1 percent per year. Some manufacturers have made progress on some vehicles, such as the latest generation of Jaguar XJ, which dropped several hundred pounds thanks to a switch from steel to aluminum construction. Of course that adds cost, so we will have to pay in some way. Go check out the interview at the Read Link.
