What's most stunning about the BMW i8 Concept Spyder isn't the 350-hp plug-in hybrid technology, the laser-powered headlights or the auto-show touches such as folding electric kickboards. It's that BMW plans to build something with most of these features, in a car looking much like this, within a few years. This is not a dream. Displayed at the Paris Motor Show, the concept wears an exterior that while still futuristic, represents a viable look at what BMW will build in two years. When BMW chief designer Adrian von Hooydonk told the production i8s would strongly resemble the concepts, this -- the layered bodywork, the laser headlights and the tri-tone accents -- was what he meant. Even the i8 Concept Spyder's scissor doors look less showy than purposeful here.
