The Aeromobil 3.0 flying car looks like something straight out of Robotech, and it really does fly!
MotorAuthority has the whole story:
The Aeromobil transforms from plane to car by folding its wings behind the cockpit. They fit alongside a boom that houses a shaft for the rear-mounted propeller, and serves as the mounting point for the flying car's tail. Despite all of the extra bodywork, the Aeromobil will supposedly fit in a standard parking space, and run on pump gas. However, given that the Transition's Rotax 912 engine runs on 91 octane, Aeromobil owners may have to splurge for premium as well.
