'''Moller Skycar M400''' er et personligt [[VTOL]] (Vertical Take-Off and Landing) [[luftfartøj]]: en "[[flyvende bil]]" -- kaldet en "volantor" af dets opfinder [[Paul Moller]].
Hensigten med M400
Den bliver beskrevet som en [[bil (køretøj)|bil]], da den skal kunne anvendes som et almindeligt [[transportmiddel]] med automatisk flykontrol enhver kan styre. Føreren skal kun angive [[retning]] og [[hastighed]] og [[pilot]]erfaring er ikke nødvendigt.

'''Skycar''' anvender billige [[Wankelmotor]]er og hardware, og dens masseproducerede pris vil ligge i omegnen af en kvalitetsbil. Prototype M400 Skycar koster pt (2007) 1 million [[USD]].

Dens egenskaber omfatter en flyvehastighed på 600 km/t, 1.450 km rækkevidde på én tank, 8 low-emissions Wankelmotorer, [[garage]]størrelse,
En mindre udgave af de 8 low-emissions Wankelmotorer som er i M400, er i [[Moller M200X]] og disse motorer kører på en blanding af 70% ([[bioætanol|bio]])[[ætanol]] og 30% [[vand]]. Tidligere modeller kørte på [[benzin]]. Ætanol/vand brændstofblanding gør brændstoffet stort set ikke-brændbart udenfor motorerne, hvilket mindsker brændrisikoen betydeligt. Vandet gør at motorene køles, kan klare højere kompressionsforhold og dermed kan yde mere, end med 100% ætanol. Blandingen gør også at motorene opfylder [[Californien]]s strenge krav; SULEV (''Super Ultra Low Emissions Vehicle'').
Den største ulempe er [[brændstof]]forbruget - sålænge fossilt brændsel benyttes - og [[støj]]en. Selv hvis brændstoføkonomien bliver ligeså god som en almindelig bil, er det klart, givet de højere hastigheder, at disse fartøjer vil blive brugt til meget længere pendling og rejser.▼

▲Den største ulempe er [[brændstof]]forbruget,
En mulig anvendelse af Skycars er i redningssituationer.

Investorer fra Kina er interesseret i bilen, og der er forlydener om at bilen kan ankomme til OL 2008 i Beijing.

A sister NASA entity is called the Personal Air Vehicle program. Together, the groups are trying to figure out how to create an infrastructure and the flying contraptions that would allow us to get around like the Jetsons...To do that, the nation would need a new air traffic system, autonomously run by computers and guided by global positioning satellites. It would have to make sure that thousands of small aircraft could buzz around without bumping into one another. That's the technology NASA will demonstrate next year..."
