@LiiMuRi So build one. That’s what this is about. You can do it.

I’ve always loved those small convertibles. And the electric version would be my dream car. So cool.

Thank you for your reply Jack. I have to admit, I am a fan of the Aptera, and it is a pity that the vehicle looks like it will never reach production. Glad to hear you are doing OK with your batteries. Good luck with the Mini.

mid thirties….as in thousand??

marionrickard September 15, 2010 at 2:22 AM

The basic roller is mid thirties with no engine. We’re working with Special Editions Inc to do a turnkey electric completed in the high fifties.

There won’t ever be a production Aptera I’m afraid.

If anything, we are seeing an increase in range. This is normal during the first part of battery life with these cells.

Prismatics are much easier. The small cells put out a lot of peak current, but have a lot of issues.

so this is like a kit car then? how much does it cost to get something like that?

ccoasterdesigner September 15, 2010 at 2:56 AM

Yes but think of the engine that a lot of people will be more amazed with. :) It is a bit sad though…

marvinbenz September 15, 2010 at 3:42 AM

should have showhoned the 993 gt2 motor in there instead hehehe

marionrickard September 15, 2010 at 4:08 AM

There IS no production ready Aptera. There apparently never will be. The company founders are “out” and unless a government “bailout” loan appears, it is most likely the end of Aptera.

Pioneers – you can identify them pretty easily. They are usually found face down on the side of the road with arrows in their backs.

re 27/11/09 friday programme
Hi jack

The porduction ready aptera will have roll-down windows.

Have you seen a reduction in range in the roadster?

Nissan have almost doubled the capacity of their battery, and they use prismatic cells.

AC Propulsion, and Teslas idea of using of the shelf batteries is flawed, some things dont scale-up very well. As far as I know, all other companies are using prismatics, GM, Nissian, Aptera etc

Seriously, you ought to start your own company. Honestly, i think a bunch of you guys should get together with calm heads, the right people, and modest budget, it can be done. What kills the electric car i think is price. Tesla is overpriced, i think their cars look nice, but not for me, and most of the population. You can’t have rich people without poor people. I’d rather spend $50,000 on 3 like new saturns that i can covert latter into EVs.

whatyouwannamyfriend September 15, 2010 at 5:31 AM

Thank You so much for your very wise and excellent video Sr.

silon2 September 15, 2010 at 6:23 AM

I’d prefer just 4 motors inside the car, not in the wheels. It’d be great for 4WD.

smcc44 September 15, 2010 at 6:46 AM

Jack Rickard has cut a classic with this video.
He is well thought out in what he says and makes the right call each time.But the real star of this movie is the car, a 1957 356 Speedster Porsche. Middle of the road and able to charm just about anyone with it’s fiber glass body and amazing elegance. I would take this newly-built classic Porsche any day before the Tesla Roadster. That is saying a lot.
This movie serves as an eye opener to all about the road ahead and what it can be.Wonderful!

marionrickard September 15, 2010 at 7:30 AM

Pretty much. 24kWh in a 2190 lb car is actually pretty much an energizer bunny on steroids.

2point6x4 September 15, 2010 at 8:11 AM

do you have the energizer bunny under that hood : )

ez3usx2 September 15, 2010 at 8:38 AM

wow great car and nice conversion.

i like your ride a lot better than the goverment motors(GM)chevy volt.who wants to pay 40 grand for something that makes a pinto look like a caddy?your ride is so cool.

the world needs more people like you and less people that throw sticks at people like you.

have you seen the lincvolt neil young is working on?its on youtube check it out.

many thanks to you and people like you for trying to make the world a better cleaner place.

Thanks. “Design” can vary from engineering specifications, to Architectural specifications, to product/ architectural “form” design without specs.

Think “Industrial Design.”

marionrickard September 15, 2010 at 9:40 AM

It’s a pretty loud design, the music I mean. The shape is nice. I think of “design” as a schemati type diagram showing component selection and connections.

TayouJin September 15, 2010 at 9:41 AM

That’s a nice car. I like the idea of a classic EV. Check out my design and tell me what you think.

nd318865 September 15, 2010 at 9:43 AM

Marion: Sure seems like an idea though. Unsprung weight is certainly an issue. We’ll see one day. Thanks again for your thoughts and imagination. Jim T.

marionrickard September 15, 2010 at 9:47 AM

Not really. This concept comes up a lot, and disappears from the landscape a lot. It’s a very interesting concept, but it appears to be one of those things that always has “just one more thing” to be worked out.

I guess I think the forces acting on a traction wheel are not a good match for an electric motor design. And the unsprung weight problem probably leads to some real problems of reliability. If it works great for 4000 miles, that’s not working.

nd318865 September 15, 2010 at 10:22 AM

Marion; A quick question re. in-wheel electric motors like the concept Volvo ReCharge. Their website months ago gave little information. Land Rover is/was showing a diesel/ generator/ 4 in-wheel motor concept as well. Any thoughts? Jim T.

nd318865 September 15, 2010 at 11:00 AM

M O N E Y. I’ve worked my — off driving for 40 years. Somehow managed to survive but never prosper. In the 70′s I remember seeing a truck equipped with an electric driveline retarder. Helped control speed on downgrades. Byproduct was heat! A heat exchanger like train engines use for the same purpose today. Whats needed is the retarder/ motor, controllers, nanofilm roof and assorted wiring/ batteries and money. Your 356 is much more possible, than a nation of hybrid big rigs powered by the sun.
