“Terrafugia Transition” – blend between car and aircraft that can actually fly as well as drive.

The Terrafugia Transition is a light sport, roadable airplane under development by Terrafugia since 2006. On the road, it can drive up to 70 miles per hour (110 km/h) with normal traffic. The Transition Production Prototype’s folded dimensions of 6 ft 8 in (2.03 m) high, 7 ft 6 in (2.29 m) wide and 18 ft 9 in (5.72 m) long are designed to fit within a standard household garage. When operated as a car, the engine power take-off near the propeller engages a variable-diameter pulley CVT automatic transmission to send power to the trailing-suspension mounted rear wheels via half-shafts powering belt drives. In flight, the engine drives a pusher propeller. The Transition has folding wings, pusher propeller and twin tail.

The experimental Transition Proof of Concept’s first flight in March 2009 was successful and took place at Plattsburgh International Airport in upstate New York using U.S. Federal Aviation Administration (FAA) tail number N302TF. First customer delivery, as of March 2009, was originally planned to take approximately 18 months and occur in 2011. On July 1, 2010 it was announced that the Terrafugia Transition had been granted an exemption from the FAA concerning its Maximum Takeoff Weight (MTOW) allowing the Transition to be certified with a take-off weight up to 1,430 pounds (650 kg); the limit matches the MTOW for amphibious light-sport aircraft. The extra 110 pounds (50 kg) granted by the exemption provides more weight allowance for the mandatory road safety features such as airbags and bumpers

After undergoing drive tests and high-speed taxi tests, the production prototype completed its first flight on March 23, 2012 at the same airport in Plattsburgh, New York that was used for the Proof of Concept’s flight testing.[20][21][22] The production prototype then made its auto show debut at the 2012 New York International Auto Show in April 2012.[23] In June 2012, Terrafugia announced that the Transition had completed the first of six phases of flight testing.[24][25] By July, the second phase of testing was underway, expanding the performance envelope in the sky and continuing drive testing on the ground.[26] In January 2013, development continued and the company announced that it might be necessary to construct a third, completely new prototype, due to the large number of modifications required.[27] The modifications to date are said to appear to have improved the previous handling characteristics.[28] By March 2014, the design of the third, updated prototype had progressed to finalization of the major structural members[29] and a statement to investors said that it would be used in final compliance testing for certification before the first customer delivery which was then estimated to take at least another 18 months and occur “in 2015”.[30] By April 2014, 12 two-person test flights had taken place; this was the first time that anyone other than Terrafugia’s chief test pilot had flown the Transition.[31] As of 22 August 2014, first customer delivery was hoped for in about 18 months “in the second quarter of 2016.”[32]
