Aptera Reboot - Improved

Sadly, the vehicles that are becoming more stable from having a low center of gravity, that is to say your typical EV, have terrible braking distances due to their increased mass. The Tesla Model 3 has a stopping distance that's longer than a Ford F150's.

Aptera is evidently half the mass of a Model 3 so will be interesting to see what the braking distance is on that one.

Our paved roads generally support the moose test maneuvers. Our gravel roads (specifically on my route to a summer cabin) on the other hand, are narrow roads with not much room to swerve, coupled with steep ditches (in places) that end up in water (in places). These are not a great place to swerve off the road to miss a moose. But it may be better than hitting the moose ... that's what I'd like to figure out.

Is there version of the 'moose test' (perhaps called something else) where you hit the moose, take out the legs, and have the 1500 lb animal land on the windshield? I'd like to see whether the front seat passenger's survive, if the leading edge of the roof will crumple to reduce deceleration, or if it peels back like a tin can, or maybe maintains structural integrity and keeps the moose out of the cabin.

If it's any consolation, I saw what happened when a brand new diesel excursion attempted that manuever on a steer. Everything front of the front door hinge was kinda missing, however, the occupants lived through it although not unscathed.

Did you ever replace the igbts in your controller?

When I was a kid my uncle had a Subaru we all called the Moose Killer that would only shift into 2nd and 4th. He hit a moose, but in a station wagon like his the moose rolled over the top. The danger of having a moose come in through the windshield is likely more of a problem in a CUV. You can hit dear that will wreck the windshield in a smaller car but the deer are smaller. I hit a mule dear in my first car, a 1984 Toyota Corolla, at about 60mph. Even though it was a large buck, it didn't come through the windshield even though I hit it hard enough for it's guts to come out.

I think that where a road doesn't allow you to steer out of the way should be driven slower. I've driven a lot, sometimes over 50,000 miles per year, and mostly on narrow mountain roads full of deer, elk and even moose at times. I've only hit one other deer after that and hit it much slower with only the headlight. There have been countless times that a deer jumped our right in front of the car or I've came around the corner and there were a herd of deer in the road.

The key is to drive for the conditions, respect speed limits and to pay attention. I've known of others that beat up their vehicles with hitting deer because they insist on driving fast. Even going 60mph instead of 50mph (assuming that 50mph is the speed limit) will double your stopping distance in any vehicle. People that say they're only going to go 5 or 10 mph above the speed limit don't realize the amount of stopping distance they're adding.

Half the weight and 3/4 the wheels.
I'm sure tesla will beat it like a rented mule on a road track.

Teslas already take longer than a Ford F-150 to stop. Are you saying that the Aptera will be even worse? Halt the weight should help. But it does have less wheel contact to the ground with three wheels.

Aerodynamically efficient problems require aerodynamically efficient solutions.

Here's a pretty technical-heavy interview!

You keep repeating that, but it was an ABS bug that was fixed years ago.

Thanks! I need to research more. The internet doesn't allways make it easy.

It went from 152 to 133ft at 60 to 0mph braking with an over-the-air update, a 19ft change!

133ft is the average for a midsized run-of-the-mill car. A sports car will average 120ft, or 13 ft less. A small car will do an average of 130ft.

Of course, that is if Consumer Reports is to be trusted...
