But yes, the point of a car like this is to be able to run supercar performance with an electric car, to show that EVS aren't just golf carts, and that performance EVs don't have to have a useable range of 40 miles before you have to charge them overnight.


You can't be serious can you? I own a Hybrid and fully aware what the engine is for. I thought it was overkill to have 2 turbines when no one will be needing all that power all the time (Meaning using 2 turbines to charge the batteries while they are being depleted). 10 seconds is more than enough time to get to highway speeds. They must be going very slim on batteries since the 1 turbine has one billion hp.

Owning a hybrid doesn't mean you understand the difference between a parallel hybrid, which describes every hybrid currently on the road, and a series hybrid, which is what this car and the Chevy Volt are. So I'm not altogether certain you do know what the engine is for in this case.

And could you explain please why one turbine is all that will be necessary, particularly as pertains to the performance they're trying to achieve with this car, or for that matter why you believe one turbine has 1 billion HP? What I've read is that each turbine is 95HP.

That's not the whole story. While any fuel that burns may work chances are there is a time limit to how long you can burn it. For example certain fuels in the CF34-3B1 engines can be used in a pinch but can't be burned day in and out without causing damage.

I'm pretty sure turbine output is measured in units of thrust, not horse power, and it's difficult to convert between the two.

Engineers have managed to express turbine output in horsepower for decades. And the ones proposed for this car are measured at a combined total output of 188HP.
