I suppose it does have 4 wheels and (mostly) meet the length and width of the other cars. The question I have now is I wonder how badly it messes with the aerodynamics of the car if you turn it around into a Y configuration like a Can am Spyder. My guess is it should be more stable in corners like the Can-Am (in comparison to other trikes which are prone to roll over) and while it might not have the same coefecient drag as the deltawing the aerodynamics would be better than the rest of the rectangle configuration vehicles. I have no idea how it would impact tire wear though. The DeltaWing config seems like it works for that. Beisswenger Design October 26, 2012 11:20 AM It's the pre-Tumbler bat-mobile! Mirmillion October 26, 2012 12:27 PM Lower drag is the holy grail - nice work. Does it need to have a certain length to width ratio to achieve this? What about the application of this config to passenger cars and, in particular, electric and/or hybrid? YuraG October 26, 2012 12:54 PM the theory says that delta trikes are less stable while cornering than tadpoles, needless to say 4-wheelers. thanks nissan for new evidence to the contrary! Bruce H. Anderson October 26, 2012 01:21 PM As one of the earlier non-naysayers, I say YAY Nissan. jerryd October 26, 2012 02:38 PM As an EV trike and reverse trike with extremely low CG builder/driver I'm still skepitcal on this unit because in cornering it's the width of the front that matters for traction. Maybe they make up enough in the straights to make up for losing speed in the curves. While neither of my 3wheeler are likely to roll, in fact almost impossible on the RT, the trike has less cornering ability that the RT does by a large amount. I too go for the lightweight, low drag route to high performance, EV range but the aero drag comes mostly to frontal area which the Delta still has, just in the rear. We'll just have to see if it really works by comparing it to a similar weight, power, aero with 2 normal width front axle/wheels. An Indy car or F-1 against it would be a more fair comparison.

Chris7527 October 26, 2012 09:42 PM Yes it may be faster due to more aerodynamic design but there may be a reason other manufacturers dont use the same kind of chassis. The reason may be that seems more unstable than conventional racecars so gaining speed but sacrificing stability. Bruce Miller October 26, 2012 11:03 PM With these concepts in mind and Ultra Light construction materials involved through-out, will this Asian engineered 'miracle' prototype an economical commuter to save hard pressed American 'burb dwellers long enough to get out of the massive debt they have incurred, or will Feds actions as money printers extra-odinaire force the purchasing power of the U.S. Dollar and therefore U.S. paychecks so low they can no longer afford gasoline for their commute? Dawar Saify October 27, 2012 01:39 AM A low center of gravity has made up for the instability in design but promoting less wind resistance. With an engine and wings, anything can be made to fly. The design remains at the basis, unstable and technology and research cannot be carried forward on a similar platform, because even though it can be done, it's in the wrong direction. This same thing could be made to fly, entirely possible, but not the right direction. One solution for cornering and making It viable is that. During turns, the engine power in the inner back wheel is eliminated.
