Its aluminum and carbon fiber frame yield a weight of only 1500 pounds.

Its aerodynamic shape gives it a coefficient of drag of only 0.20cd. (Can someone provide something we can compare this to?)

It has an intentionally sparse interior that exposes the frame of the vehicle, much like a bicycle's frame is exposed.

It gets approximately 95 miles per gallon (or 40km/l)

It looks cool too!

Nice car. You probably would need to take out a second mortgage for it and insurance payments on that would be through the roof. Otherwise, it's a nice car.

I don't know... it is probable that Honda won't release it stateside for several years (I could be wrong) but their Insight vehicle is very similar:

1850 pounds, aluminum construction, 65mpg. Insurance for me for 6 months is $832.90. Invoice on an Insight is $20,000 or so.

One point worth mentioning is that I heard Honda is actually losing money on the Insight. I don't know what that means for the sales of the IMAS if they sell it in the USA... they may accept a loss on that car as well.

This isn't an actual car, and won't be for sale ever. It looks interesting though I couldn't get excited about driving with an exposed frame. Get in an accident and it would likely mess you up that much worse.

It does look like an Insight. Funny, I just saw an Insight on the freeway today that was going in excess of 80mph. It tried to pace it, but I stopped after a certain point.

What, were you on your bike or something? :D

That's pretty aero. I remember the Honda CRX having a CD of around .29

That's pretty light. The mclaren F1's about 350 lbs heavier but it seats 3, gets around 20mpg, and has a 620bhp V12 with an aero coeff of 0.3.

The 2nd generation Toyota Prius has a .26 Cd

The Honda Insight has a .25 Cd.

These are some of the lowest for production cars.

It's most likely not passive bodywork on a tube-frame, that's old-school 1970s stuff. Looks like monocoque construction which yields the highest strenght-to-weight ratio. Probably uses aluminium for bolt-on attachment points for engine, bumpers, suspension, seats, etc and carbon-fibre to connect those alloy pieces. Similar to the Mclaren or Enzo construction methods.

I just like having something between me and the part of the car that would absorb energy from an impact. Even crate paper would be nice, then I wouldn't have to look at it and worry about crumple fragments flying into my eyes :p

hoping this will become the new honda insight..

If you are saying the F1 is heavier than an Insight... just think of what you could do with this car...

You could put a nice turboed Hayabusa engine in it... like they did:

http://zcars.org.uk/ultima/index.htm

They put dual Hayabusa motorcycle engines in a (finished weight) 980KG car for a BHP of 1000.

So I'm assuming you could pull 500BHP out of one engine?

I don't know how much those engines weigh but we could say 500lbs (They go in motorcycles, this is probably way over the actual weight).

So remove about 300 lbs from your base of 1500lbs for the stock engine, and add 500lbs, and you have an 1800lb vehicle with 500bhp and a cd of 0.20. Freakin insane. Of course, you would have to make some other adjustments as well, like adding some really awesome brakes, and you'd probably need a non-stock transmission. Well... you'd also need an electric motor in there so you could go in reverse.

But that's pretty crazy potential for a mad-crazy-fast vehicle. Almost or better than F1 specs at probably half to a third or quarter of the price.

But that would require someone who had a clue about autos and what they were doing. Not me.

Oh... and some money.

And I forgot... that would also kind of destroy the whole point of this vehicle: to get insane crazy gas mileage.

jakemoffatt 09-09-05 02:52 PM

I'll bet it has a sealed undercarriage.

The Honda company actually started out with bicycles.

Therefore, ALL of their cars have been designed after a bicycle.

(Just looking for trouble.)

"I don't know how much those engines weigh but we could say 500lbs (They go in motorcycles, this is probably way over the actual weight)."

Stock Busa motor weighs about 175lbs... Add about 50-lbs for the extra plumbing of turbos.

There is the Ariel Atom. Not the most aerodynamic, but that thing is fast with it's great power to weight ratio. Weighs 456kg and has a Honda 1.8L VTEC engine. 220BHP.

Rumor has it, it's going to be sold in the US and may come with a 2.4L engine.

BMW put together a turbodeisel that has a drag coeff. of .14. It moves pretty well, and gets about 90 mpg.

They have no plans to release it. Just proving that they can do gas milage too, they just dun wanna.

Then there's the Lotus Elise and Exige. I did the 2001 OTC where there was a Lotus Elise and 340R. They kicked butt!!! I would imagine the Exige can offer Ferrari-F40/Enzo levels of performance... :)

How would that come close to passing even 10% of American safety requirements. Don't get me wrong, seeing the Atom in the USA would be awesome, but if it did make it I doubt it would be the same car.

Perhaps it will be limited to track use only? I dunno. Or perhaps it'll come into the States as a "kit car"??

Actually, Honda originally made engines that were installed onto bike frames, not bicycles themselves.

My 1985 Honda CRX HI got 51 MPG. It used less gas than my Honda motorcycle. The motorcycle only got 44 MPG. Some impressive technology for 1985.
