To win, vehicles must complete both races with the lowest overall time averaged over all scoring stages while still meeting the requirements for 100 MPGe fuel economy and low emissions of carbon dioxide and other pollutants.
So if the Aptera "only" has to do a 100 MPGe it can do a very good average speed per stage right?

I read this in the draft guidelines:

Energy (Fuel Economy) – 100 Miles per Gallon of Gasoline Energy Equivalent (MPGe)

Electric advantage. Issue: Because AXP will measure fuel-economy pump-to-wheels (PTW), with upstream energy-conversion efficiencies not considered, does electricity have an unfair advantage? Probable Answer: After reconsidering all of the arguments on both sides of this question, we are inclined not to change the current requirement of 100 MPGe. However, we will be more thorough in explaining our position. One relevant point is that pure electric vehicles in fact have to achieve higher than 100 MPGe in order to meet the GHG emissions requirement. For example, given the currently-proposed limit of 200 g/mi based on the 2005 national grid, electric vehicles would have to achieve about 136 MPGe.

I love that the pic they used for the article is the Aptera!

That's cool because when I posted the article here there was a photo of a formula car cut out of box tree. So they changed it for the better. :happy0025:

The Favorites: No ink or expense is being spared on the well-developed projects being put forth by companies like Aptera (pictured) and Tata Motors. Aptera was founded in 2006 and is working on an uber-aerodynamic, three-wheeled electric two-seater with a 120-mile range. Tata Motors is India’s largest automobile maker and builder of the reengineered air-compressed engine.
Nice to be listed as a favorite . . . but it raises expectations.

For me, the Avion will be the one to beat. That's a traditional-looking 2-seater, 4-wheeled car with an ICE that does 130+MPG. Even if the Aptera is more futuristic, the Avion approach is more simple and easier to achieve.
