The body weighs around 360kg, with a 60kwh battery it supposedly weighs around 800kg (the smallest and lightest option is 25kwh), with a drag coefficient of 0.13.
In comparison to some of the most efficient cars - the Hyundai Ioniq 6 is around 1,860kg with a drag coefficient of 0.21. Tesla Model 3 is around 1760kg with a drag coefficient of 0.219.
It's going to be a whole lot more efficient than the average car just based on these numbers.
Now it depends on how much of the car's surface will be covered by the solar panel and what's the panel's efficiency.
The Honda civics in the 1980's weighed around 800 or so kg as well. You know one of the reasons they got heavier? Crash ratings and safety features.
So once again I'm calling bs that they will get 45 miles out of this. Even if they got it classified as a motorcycle and scape around the car safety requirements, it still won't get a real world 45 miles a day from solar charging. Your math will never add up to that.
The Honda Civics of the 1980s did not have a drag coefficient below 0.2
Come back in a year or so and we'll see who has to eat their words.
That's a weird comparison to make. The Aptera is smaller and uses different materials.
Afaik it's going to be classified as a motorcycle in many states in the USA, but they're still aiming for a high rating. I know they have crumple zones and a safety cell made from composites akin to F1 cars.
Whether what they're planning will be enough, we'll only know for sure once they test it.
The math works quite well as long as the information is accurate.
Of course things can always turn up to be different in the end product.
But from the information we have now, ~4 hours of good sunlight conditions will be enough for 43 miles.
