If only this car ran on hype, it would be the fastest car on the planet.

About 40 miles to the blog? Even better if you switch it over to run on clickbait?

Actually, above 50% charge the battery has negative inertial mass - but still it has positive gravitational mass, i.e. weight.


So you are still pushed down by gravity acting on the gravitational mass, giving you grip. But the inertial mass of the battery is negative, up to negative 1600 lbs at full charge, so the car accelerates as if it was ~1200 lbs. The electric part of the hybrid adds 90 HP on top of 200 from the gas engine, making about an equivalent of 4.13 lb/HP with grip of a 2800-lb car.

They are still working on ironing out some kinks, for example at low charge levels the inertial mass becomes larger than the gravitational mass, and quickly. E.g. below 25% charge you need a B747 tug to move the car at all. Below 10% you need a Saturn V rocket. Or you just need to charge the battery. But they will have it all fixed for 2018 MY.


Aren't they supersmart at Toyota, not only this will create the best sports car ever with excellent acceleration AND mileage AND grip, but in the process they figured out how to violate Einstein's equivalence principle and decouple inertial mass from gravitational mass. Which is YUGE, a Nobel Prize in physics is coming for sure.

If I only could find the link to that Australian tech site, you could read about it too.

Those Aussies alway have the most up to date info leaks. Damn them being a day ahead...

And will it come with the Nico Rosberg edition steering wheel . Gotta be ready with that derate mode.

The big problem is mining enough unobtainium to make all those batteries.

He's only saying things to keep people speculating. Keep us entertained and on board.

I'm guessing the entire car isn't fully aluminum and can still be made even more rigid to remove even more body flex. Although I highly doubt it can shave more than 100 lbs, It would need a serious redesign to the new ND miata style of weight savings.

1) With E85, my range is realistically only about 220 miles

2) The design of the current tank makes the car fuel starve on high-G left hand turns. Again, particularly with E85.

Thanks. I was truly baffled since it holds enough for many miles (on normal fuel) and I don't do many high-g left turns. Don't know how they could make a bigger/different style fit up in there though. Also not sure how 1 or 2 more gallons would make enough difference in miles on E85 to make the weight increase worth it.

Yeah, the capacity is just a minor thing. Fuel starvation is a pain in the ass, though. Starts to starve if you're around 1/2 tank, so I have to constantly fill up my car after every session.

Symptom of the split tank design?

Seems to be. I know some people have tried a dual-pump setup. Not sure how well that worked out. I'm not fast enough to need something like that yet.

Current tank is saddle-style. They would/could have to produce a flat bottomed tank so fuel on the side far from the pump would continue to be pumped. That would be a fairly drastic redesign that would apply really only the the racers of this world. As a person who runs e85, I'd love for them to do it, but sadly doubt it would be a priority.

You can see the shape of it here in Michelle Abbate's build.
