MonoTracer by the Swiss-based company Peraves. The current gas-powered version features a Kevlar cockpit, iPod connectivity, electric sunroof, navigation system, and even storage space for your luggage. In addition, this sleek two-seater can reach a top speed of 160 mph and get up to 60-70 mpg. An electric version which can hit 200 mph won the Progressive Insurance X Prize last Fall and will go into production this Spring. The current MonoTracer starts at $75K, but sorry, it doesn't come with cupholders.
