A car running on compressed air

[Karlos]

...but for a brief moment there was a glorius 8g acceleration, straight upwards :lol:

Compressed air isn't that lightweight, especially when you are talking about 300 bar. That's 300x denser than usual (roughly 315 kg/m^3 at 20 Celcius), even before you get to the weight of the material needed to contian it. However, it said they used a form of carbon fibre for that.

-edit-

It says on the site (under the FAQ) that the car holds 90 m^3 (at 300bar), so that's ~92kg just for the compressed air itself. I think standard batteries are a good bit lighter.

On the plus side, it get's lighter as you expend it :-D

fully electric cars with a range of 200km would have a pack closer to the 500kg range and be very slow to accelerate.

You obviously haven't seen the Tesla Roadster ;-)

That thing delivers more torque at 8000 rpm than most petrol engines do immediately after starting...

0-60 in about 4-5 seconds acceleration enough for you?

I meant it delivers more torque at 8000 rpm that a typical petrol engine does at much lower rpm, or indeed at any rpm, if the following is to be believed:



See for yourself

i obviously have seen the tesla
it also has a lithium battery (very expensive)
its also a two seater right?

Indeed it is. And so obviously styled by lotus ;-)

btw they dont state it on the site but the 200 mile range is probably at 40 to 45 mph

They quote 200 miles between charges on a standard driving cycle (whatever that actually is). I strongly doubt it manages anything that if you are constantly testing out the torque...

You can say what you like about electic cars, but I'd love to test drive that model :-D

Especially given their total inability to steer normally...
