Lowest Cd of Production Car
 

Lightyear has just released the results of their recent windtunnel tests. :cool:

A record-breaking drag coefficient (Cd of 0.20) has been reached. It's built to perform on energy efficiency. Read more on the Lightyear website News section.

What do you think? Will other EV's follow in striving towards energy efficiency?

Other EVs aside from tesla are all based on gas burner or gas burner hybrid bodies and they just don't need to be all that aerodynamic.
To get below about .25 or .23 the vehicle has to be designed around aerodynamics.

Latest entry is Sept 19.................still not seeing it...............oh, now I see it.

Still do not see where it a projected or test results number, but still watching the long video.

First you need to consider both Cd and frontal aera. I could make a jumbo jet with a low Cd but it would take an enormous amount of power because of the frontal aera.
Second, I don't think that classifies as a production car. The VW XL1 was actually in production even If not available in the USA. It was .189 Cd so it beats the Lightyear's goal.

Good points.

Looks like the earlier VW-L1 (Diesel - tandem seating) never made it into production.

The XL1 was not a 5 seater.

Who said anything about 5 seaters only?

They produced 250 right? The price was better than the zero production vehicles so far by Lightyear.

The VW XL1 is no longer in production.

But the Lightyear isn't a current production car either. That being said, once one car sets a record it holds the record until being beaten. It doesn't lose the record just because it isn't currently being produced. I have a feeling VW (and other makers) may have a few other pre-production projects out there that also might be better as well, the difference is they aren't making promises looking for deposits. Build the car, deliver it to customers, then you can start claiming record this or record that.

PS I just re-read the quote. They said "Lightyear One will likely be the most aerodynamic car available in the market." Of course the VW XL1 is available on the market, just used (although the few that have shown up are actually still actually new with like 10 miles on the odometer). So they say "likely" and they actually mean "new market".
