That makes sense, Debera. This seems like a smart way to accomplish that, given that sports cars tend not to be driven on long trips.

Jennifer, i read in some article that Nissan said they have always seen parents having a sports car their aim is to make the sports car affordable so that it becomes appealing for the young ones as well.

I didn't know that, Chuck. I know woefully little about race cars in general. But that's really interesting...and to have the support of Leonardo DiCaprio. I suppose it's politically correct for him to do that, especially if he is an enthusiast of the sport. I will take a look at that story--thanks for pointing it out to me.

Liz, EV race cars are here now. I recently saw a story about Leonardo DeCaprio investing in electric race cars. Also, we did a story about them in 2009, which is strangely missing from our site, but here's a link to a reprint of the story.

Good point, Turbineman, but maybe a future iteration of this car will have a bigger driver's seat. Still an interesting concept, even if it never makes it to production.

Nissan's position

Following is Nissan's position on the narrow front track, with no editorial comment on my part:

"While the traditional enthusiast may scratch their respective heads wondering how a car with such a narrow track can take corners, the answer is relatively simple. The narrow front track of the BladeGlider allows less weight to be placed on the front wheels. While some may say that more weight on the front tires equals better grip, the complete opposite is actually true.

"Sure, with super wide tires, extra load may result in more grip, but this is not an efficient solution, nor is it always true. For example, front-heavy cars are prone to excessive understeer -- the loss of grip at the front wheels, where the car does not turn as much as the steering demands. The thinner tires up front allow the BladeGlider to turn in crisply because only 30% of the car's total weight rests upon them. An added benefit is improved steering in terms of effort, feel and precision.

"Also, the narrow front track allows the car to have minimal lateral weight transfer through corners, at both the front and rear ends. Cars with wider front tracks dramatically shift their weight to the outside tire when turning, leaving the inside tire to do nothing. Thus, only one tire is steering the car through a corner, but with BladeGlider, both tires stay in good contact with the road surface and share nearly the same cornering load, virtually working as one unit, And thanks to the independent suspension system, each tire's effectiveness is augmented through turns."

Tadpole versus Arrowhead

The streamlining we often seen is based upon bird shapes. But, birds have that shape not for aerodynamics but, to elevate the view when walking or sitting on the ground to give greater warning of preditors. look instead to the larger fish, except for a few with weapons in the front most fish have a blunt rounded front and long tapered the tail and their medium is far more viscous than air. Look to modern aircraft, except for supersonic they do not have pointed noses. round is more efficient up to seven or eight hundred mph. The arrow head is intended to penetrate skin and muscle, not for streamlining. It is pretty looking but not the best it could be. even the BMW Isetta had a wide front stance and a rounded front which opened for the two in the front to enter and exit. That combined with two wheels placed close together on the rear gave amaizing performance for a two cylinder two cycle casoline engine, but they did not "Look" sleek enough... and BMW quit making then in only a short time. Look to the Morgan 3 wheelers or the Electric "Sparrow" for exampled of successful tadpole designs.  And for effective streamligning, look at modern submarines (Like the "L.A.class" in "Red October") Rounded nose more parabula then hemisphere and long tapered tail. That is Streamlining! actually the modern submarines are faster underwater than on the surface as the air/water interface creates a discontinuity being submerged generates less turblence in the water.

It seems a bit claustrophobic in the driver's seat.  More like a 4 wheeled trike than regular car.  How would the NHTSA crash test this; as a regular automobile or trike, which I don't think they test?

Copy of Delta Wing racecar

This is NOT a new concept, but a commercial (civilized) version of the DeltaWing race car designed by Ben Bowlby and universally panned by the racing community.  I might also add that this car, the Nissan race car derived from the original DeltaWing prototype, and Ben Bowlby himself, have been sued by Don Panoz who has patents on this concept.
