I'm not believing they'll get even close to that in a production vehicle that's US street legal.
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.
They are skirting the “street legal” and safety stuff by making an electric motorcycle instead of a car. Months (years?) ago I read something about how they are planning to tackle helmet laws in court because of this. Accident safety features are heavy, this thing is going to be a death trap on US roads in order to be as light as possible.
Overall I think that’s the right move, but I wouldn’t get in rush hour traffic in this thing.
That'll help keep it as light as they're planning. They still won't get 45 miles a day on solar unless they're doing 15mph on a flat road in Nevada during the summer. No way would it be an expected rating.
You should actually watch their videos and do some research before spewing your speculations. Seems like it's going to be pretty safe to me.
I’ve watched plenty of their videos. Despite how you took my message, I’m actually very excited and hope they make it to full production. But if you think that thing is going to be safe enough when some a-hole in a Tahoe t-bones you, you’re going to be very disappointed. The problem isn’t the Aptera, it’s the ridiculous sized SUVs already on the road.
