British designer Philip Pauley has created a concept car called the Halo Intersceptor thats transforms (with the use of a few extras) in to a Helicopter, Jet and Boat. Check out the video after the break.
From the main car section the user would then use either the Halo 120, Halo 46 and Halo 22 to transform.
The Halo 120 section converts the vehicle into a little private jet that can climb 25,890 feet a minute, Halo 46 is a helicopter with a seating capacity for four and Halo 22 is a 36-foot-long powerboat with a race-bred double hull and an engine you can throttle up to 63 knots. All totally conceptual but hey what a concept.
